PHARMACEUTICAL ASSOCIATION FOR CONVERTING A NEOPLASTIC CELL INTO A NON-NEOPLASTIC CELL AND USES THEREOF FIELD OF THE INVENTION

The invention relates to associations, combinations, compositions, kits, methods and processes for the design, preparation, manufacture and/or formulation thereof, and methods and uses thereof for converting or recoding a neoplastic cell into a non-neoplastic cell and treating and/or preventing a neoplastic disease.

BACKGROUND

Neoplastic cells, such as cancer cells, are generally characterized by abnormal and/or uncontrolled proliferation leading, in most cases, to the development of a neoplastic disease, such as cancer. Conventional methods for treating neoplastic diseases include surgical treatments, radiotherapy and chemotherapy.

Surgery is usually practised in order to extract localised (non-circulating) neoplastic cells from a patient's body and is most generally combined with radiotherapy treatments. As well as being limited to the treatment of very early stage, non-metastatic tumors, surgery is an invasive medical procedure which remains traumatic for the treated patient, involves the permanent removal of tissues or organs (which is sometimes not possible as some organs or organ parts are not accessible or cannot be removed due to life threatening consequences), in some cases has been shown to "unblock" dormant tumors, while only offering a "visual" selectivity to distinguish between healthy and tumor cells. Radiotherapy also presents some significant drawbacks for the treated patients including the high cost of the radiation therapy equipment, the high cost of the treatment itself, side effects associated with the damage or destruction of healthy cells, limited effectiveness against metastasized neoplastic diseases, skin rashes caused by external beam radiation, the potential deleterious impact on the functioning of tissues, glands or organs located near the site of treatment, and the possible development of secondary cancers as a result of exposure to the radiations.

Conventional chemotherapy methods generally involve the administration of small synthetic regulatory molecules which inhibit specific intracellular target proteins thought to be responsible for the neoplastic phenotype of the cell. One example is the inhibition of tyrosine kinase signal transduction by small molecule inhibitors to regulate uncontrolled cell proliferation. Typical chemotherapy methods also include treatments wherein DNA is covalently altered by e.g. DNA strands crosslinking, or treatments wherein the polymerisation and depolymerisation of microtubules is enhanced prevented thus provoking apoptosis of the damaged cell.

Another method for treating neoplastic diseases includes gene therapy wherein a missing or defective gene is replaced with a functional, healthy copy, which is delivered to the target dysfunctional cells using a "vector." Gene transfer therapy can be done outside the body (ex vivo) by extracting bone marrow or blood from the patient and growing the cells in a laboratory. The corrected copy of the gene is then introduced and allowed to penetrate the cells' DNA before being injected back into the body. Gene transfers can also be done directly inside the patient's body (in vivo). Gene therapy has been applied to a few specific cases of blood cancers (chronic lymphocytic leukemia (CLL), acute lymphocytic leukemia (ALL) and multiple myeloma) through a particular form thereof in which the genetically modified cells were not the neoplastic cells themselves but instead the immune T-cells. Modified T-cells could then target and destroy specific blood cells (neoplastic as well as healthy). The body of the patient is then able to produce healthy blood cells and eventually provide a treatment to certain blood cancer types. However, gene therapy is generally best suited for the treatment of diseases caused by a single defective gene, not neoplastic diseases, which often involve multiple defective genes. Overall, issues such as the correct integration of therapeutic DNA into the genome; the immune system response to the introduction of foreign DNA into the cell; the toxicity, immune and inflammatory responses; gene control and targeting issues of the vectors (usually viral) required to transport the DNA inside the cell; the difficulties associated with the treatment of multigene-associated neoplastic cells; the possibilities of inducing tumors if the DNA is integrated in the wrong place in the genome; and/or the significant cost usually involved with such a therapy, have greatly undermined the development of gene therapy.

Other intracellular therapies have been contemplated for the treatment of neoplastic diseases using, for instance, micro-ribonucleic acids (miRNAs) or small interfering ribonucleic acids (siRNA). Under these conditions, the neoplastic cell is generally forced to down-regulate or repress the expression of one or more specific target genes (e.g. oncogenes) thus inhibiting the expression of defective and/or defecting proteins (e.g. oncoproteins). One example is the repression of genes encoding key proteins in the proliferation of cancer cells such as vascular endothelial growth factor (VEGF) and kinesin spindle protein (KSP), thus controlling cancer proliferation.

Neoplastic diseases may also be treated using immunotherapy such as antibody therapies wherein the antibodies bind to a target antigen typically on the surface of the neoplastic cell. Cell surface receptors are common targets for antibody therapies and include the epidermal growth factor receptor, HER2, CD52, the vascular endothelial growth factor-A and CD30. Once bound to an antigen (e.g. a cancer antigen), antibodies can induce antibody-dependent cell-mediated cytotoxicity, activate the complement system, prevent a receptor interacting with its ligand or deliver a payload of chemotherapy or radiation, which may all lead to the induction of neoplastic cell death. For instance, Cetuximab (Erbitux) is a chimeric IgG 1 monoclonal antibody that targets the extracellular domain of the epidermal growth factor receptor (EGFR). Once a ligand binds to the EGFR on the surface of the cell, signalling pathways are activated inside the cell that are associated with malignant characteristics such as cancer cell proliferation and invasion. Cetuximab competitively inhibits ligand binding, thereby preventing EGFR activation and subsequent cellular signalling. It also activates programmed cell death (apoptosis).

Other intracellular treatments such as messenger ribonucleic acids (mRNAs) -based therapies have also been used in the treatment of neoplastic disease wherein administration of mRNA material into a neoplastic cell causes the neoplastic cell e.g. to express specifically encoded antigens and causing the neoplastic cell to be eliminated by the host immune system.

Differentiation therapy is another technique which was developed on the concept that the acquisition of the malignant phenotype (such as neoplasia) in a cell is considered as a progressive de-differentiation or a defective differentiation of that cell. Thus, as e.g. tumor cell populations evolve to greater degrees of malignancy, they usually lose more and more differentiation markers. This led to the suggestion that it may be possible to treat cancer by inducing differentiation of cancer cells. However, some scientific reports have shown that the differentiation therapy does not in fact induce cancer cells differentiation but instead restrains their growth thus allowing the application of more conventional therapies (such as chemotherapy) to eradicate the malignant cells. Examples of differentiation therapy involve the forced (re- )expression of some specific micro-RNAs and thus rely on an intracellular action generally presenting the same drawbacks as in any other intracellular therapies such the siRNA and gene therapies.

A shortcoming of the medical therapies relying on previously reported methods of treatment are numerous and mainly resides in the incapacity of providing a sustainable therapeutic effect i.e. the treated cells are not healed but instead are either destroyed (e.g. through induced apoptosis) or their proliferation reduced or temporarily halted using a sustained administration of therapeutic molecules until, in most case scenarios, neoplastic cells are able to adapt themselves and render the therapy ineffective. Interrupting a known therapy will usually lead to resumption of the neoplastic cell state.

Other drawbacks associated with previously reported therapies are numerous. For example, they may be very invasive and traumatic for the patient; they may necessitate permanently removing neoplastic tissues or organs which may be in some cases not practicable or feasible (organs or organ parts not accessible) or not possible due to life-threatening consequences; they may not be applied to or have limited effectiveness against metastatic neoplastic cells; they may not possess the ability to remove or treat all neoplastic cell types (i.e. neoplastic cells having different invasiveness levels and/or of different lineage origins); they may potentially "unblock" dormant tumors; they are often expensive; they may damage or destroy healthy cells alongside neoplastic cells thereby causing adverse treatment side effects; they may cause skin rashes and skin sensitivity; they may not target cancer stem cells as these are not proliferating; they may have a mutagenic action even towards healthy cells; they may require sustained administration to maintain treatment therapeutic effects; they may display very high cytotoxicity; they may cause multi-drug resistance whereby a drug having an intracellular action is no longer imported inside the cancer cell or is systematically exported outside of the cell.

None of these previously known methods allows for the effective recoding of a neoplastic cell thus permitting conversion of a neoplastic cell into a non-neoplastic cell. The present invention thus provides associations, combinations, compositions, kits, methods and processes for the design, preparation, manufacture and/or formulation thereof, and methods and uses thereof for converting a neoplastic cell into a non-neoplastic cell including converting or recoding the neoplastic cell to induce, provide and/or reintroduce self-recovery or self-healing capabilities thereto.

Neoplastic diseases start when a cell (or neoplastic cell) is somehow altered so that it multiplies out of control. Tumors and cancers are some examples of neoplastic diseases. A tumor is a mass composed of a cluster of such abnormal cells. Most cancers form tumors, but not all tumors are cancerous. Benign, or non-cancerous, tumors - such as freckles and moles - stop growing, do not spread to other parts of the body, and do not create new tumors. Malignant, or cancerous, tumors crowd out healthy cells, interfere with body functions, and draw nutrients from body tissues. Cancers continue to grow and spread by direct extension or through a process called metastasis, whereby the malignant cells travel through the lymphatic or blood vessels, eventually forming new tumors in other parts of the body.

The term "cancer" generally encompasses more than one hundred diseases affecting nearly every part of the body, and all are potentially life threatening. The major types of cancer are carcinoma, sarcoma, melanoma, lymphoma, and leukemia.

Carcinoma is a type of cancer that develops from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that generally arises from cells originating in the endodermal or ectodermal germ layer during embryogenesis.

Sarcoma is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancerous bone, cartilage, fat, muscle, vascular or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Human sarcomas are quite rare. Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.

Melanoma is a type of skin cancer, which forms from melanocytes (pigment-containing cells in the skin).

Lymphoma is a group of blood cell tumors that develop from lymphocytes. It is sometimes used to refer to just the cancerous ones rather than all tumors. There are two main types: Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), with two others, multiple myeloma and immunoproliferative diseases, also included by the World Health Organization within the category. Non-Hodgkin lymphoma makes up about 90% of cases and includes a large number of sub-types. Lymphomas are part of the broader group of neoplasms called tumors of the hematopoietic and lymphoid tissues.

Leukemia is a group of cancers that usually begins in the bone marrow and results in high numbers of abnormal white blood cells. These white blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding and bruising problems, feeling very tired, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically by blood tests or bone marrow biopsy.

Cancers include, but are not limited to, Adrenal Cancer, Anal Cancer, Bile Duct Cancer, Bladder Cancer, Bone Cancer, Brain/CNS Tumors In Adults, Brain/CNS Tumors In Children, Breast Cancer, Breast Cancer In Men, Cancer in Adolescents, Cancer in Children, Cancer in Young Adults, Cancer of Unknown Primary, Castleman Disease, Cervical Cancer, Colon/Rectum Cancer, Endometrial Cancer, Esophagus Cancer, Ewing Family Of Tumors, Eye Cancer, Gallbladder Cancer, Gastrointestinal Carcinoid Tumors, Gastrointestinal Stromal Tumor (GIST), Gestational Trophoblastic Disease, Hodgkin Disease, Kaposi Sarcoma, Kidney Cancer, Laryngeal and Hypopharyngeal Cancer, Leukemia, Leukemia - Acute Lymphocytic (ALL) in Adults, Leukemia - Acute Myeloid (AML), Leukemia - Chronic Lymphocytic (CLL), Leukemia - Chronic Myeloid (CML), Leukemia - Chronic Myelomonocytic (CMML), Leukemia in Children, Liver Cancer, Lung Cancer, Lung Cancer - Non-Small Cell, Lung Cancer - Small Cell, Lung, Carcinoid Tumor, Lymphoma, Lymphoma of the Skin, Malignant Mesothelioma, Multiple Myeloma, Myelodysplastic Syndrome, Nasal Cavity and Paranasal Sinus Cancer, Nasopharyngeal Cancer, Neuroblastoma, Non- Hodgkin Lymphoma, Non-Hodgkin Lymphoma In Children, Oral Cavity and Oropharyngeal Cancer, Osteosarcoma, Ovarian Cancer, Pancreatic Cancer, Penile Cancer, Pituitary Tumors, Prostate Cancer, Retinoblastoma, Rhabdomyosarcoma, Salivary Gland Cancer, Sarcoma - Adult Soft Tissue Cancer, Skin Cancer, Skin Cancer - Basal and Squamous Cell, Skin Cancer - Melanoma, Skin Cancer - Merkel Cell, Small Intestine Cancer, Stomach Cancer, Testicular Cancer, Thymus Cancer, Thyroid Cancer, Uterine Sarcoma, Vaginal Cancer, Vulvar Cancer, Waldenstrom Macroglobulinemia, Wilms Tumor.

The activation of growth factor receptors (GFR) is commonly known to promote neoplastic cell proliferation. For instance, many cancer treatments rely on the inhibition of growth factors, growth factors receptors and/or downstream signalling proteins such as protein kinases. Such inhibitors include, non- exhaustively, anti-Met (e.g. ARQ-197), anti-VEGF (e.g. Bevacizumab), anti-VEGFR (e.g. Sunitinib or Semaxinib), anti-Her2 (e.g. Trastuzumab), anti-EGFR (e.g. Cetuximab, Gefitinib or Erlotinib), anti-PDGFR (e.g. Imatinib), anti-IGF-1 (e.g. IMC-A12), anti-Ras (e.g. Tipifarnib), anti-Raf (e.g. Sorafenib), anti-src (e.g. Dastinib or Saracatinib), anti-Mek (e.g. C1040 or PD-0325901 ), anti-PI3K (e.g. LY294002), anti-PDK (e.g. UNC01 ), anti-HSP90 (e.g. 17-AGG or IPI-504), anti-CDK (e.g. Flavopiridol) and anti-mTOR (e.g. Everolimus).

Unlike previously reported treatments, it has been surprisingly demonstrated that the pharmaceutical associations, combinations and compositions disclosed herein can be used to treat, prevent and/or diagnose neoplasms (e.g. tumors or cancers) by activating growth factor receptors of vertebrate cells (such as mammalian cells, especially human cells).

As used herein and unless otherwise indicated or contradictory in context, the term "substantially" refers to the qualitative condition of exhibiting total or near-total extent or degree of a characteristic or property of interest. One of ordinary skill in the biological arts will understand that biological and chemical phenomena rarely, if ever, go to completion and/or proceed to completeness or achieve or avoid an absolute result. The term "substantially" is therefore used herein to capture the potential lack of completeness inherent in many biological and chemical phenomena.

In addition, it is to be understood that any particular embodiment of the present invention that falls within the prior art may be explicitly excluded from any one or more of the claims using the appropriate disclaimer(s) or proviso(s). Since such embodiments are deemed to be known to one of ordinary skill in the art, they may be excluded even if the exclusion is not set forth explicitly herein. Any particular embodiment of the compositions of the invention (e.g., any peptide or peptidomimetic; any method of production; any method of use; etc.) can be excluded from any one or more claims, for any reason, whether or not related to the existence of prior art.

All cited sources, for example, in certain embodiments, references, publications, databases, database entries, and art cited herein, are incorporated into this application by reference in their entirety, even if not expressly stated in the citation. In case of conflicting statements of a cited source and the instant application, the statement in the instant application shall control.

As the case may be, and unless otherwise indicated or contradictory in context, macromolecules molecular weights should be understood in the present description as being number averaged molecular weights.

The peptides mentioned in the present description may not follow the usual representation conventions. For instance, the N-terminal amino acid of a peptide sequence may be the first amino acid in the sequence or the last amino acid. Likewise, the C-terminal amino acid of a peptide sequence may be the first amino acid in the sequence or the last amino acid. For example, in the peptide sequence NAIS, "N" may be N-terminal or C-terminal, and "S" may be N-terminal or C-terminal. Consequently, for the purpose of the present disclosure, e.g. NAIS also covers SIAN, SAIS also covers SIAS, SPIN also covers NIPS, etc.

In the present application, when reference is made to a certain peptide (e.g. a GFR-binding compound as provided herein) comprising one or more other peptide(s), said one or more other peptide(s) is(are) understood to be stably (in most cases, covalently) attached/bound to at least one part of said peptide. The attachment/binding may be located anywhere on the peptide unless indicated otherwise, contradictory in context or contradictory to general scientific rules. No specific attachment/binding location of said one or more other peptide(s) to said peptide shall be assumed unless specifically mentioned.

Peptide or polypeptide: As used herein, the term "peptide" or "polypeptide" are used interchangeably and refers to a polymer of less than or equal to 100 amino acids long, e.g., about 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or 100 amino acids long. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers, non- naturally occurring amino acid polymers, peptide analogs, peptide variants and peptide mimetics. Conventional techniques for synthesising peptides involve the activation of the carboxylic acid function of an amino acid or of a peptide, using a coupling agent. This activated acid is then contacted with an amino acid or a peptide in which the N-terminal amino acid is not protected, thus forming an amide bond also called peptide bond. Coupling reaction conditions together with coupling agents are well known in the art and described, for instance, in Greene, "Protective Groups in Organic Synthesis", Wiley, New York, 2007 4th edition. In addition, suitable peptide synthesis routes are described, for instance, in Hojo H., Recent progress in the chemical synthesis of proteins, Curr Opin Struct Biol. 2014; 26C:16-23 and Saranya Chandrudu, et al. , Chemical Methods for Peptide and Protein Production, Molecules, 2013, 18, 4373- 4388, each of which is incorporated herein by reference in its entirety. There are two main strategies for peptide synthesis i.e. liquid-phase peptide synthesis and solid-phase peptide synthesis (SPPS) which is now most commonly used for peptide synthesis. Instead of C-terminal protection with a chemical group, the C-terminus of the first amino acid is coupled to an activated solid support, such as polystyrene or polyacrylamide. This type of approach has a two-fold function: the resin acts as the C-terminal protecting group and provides a rapid method to separate the growing peptide product from the different reaction mixtures during synthesis. As with many different biological manufacturing processes, peptide synthesizers have been developed for automation and high-throughput peptide production. SPPS allows the synthesis of natural peptides which are difficult to express in bacteria, the incorporation of unnatural amino acids, peptide/protein backbone modification, and the synthesis of D-proteins, which consist of D- amino acids. Very long peptide can be accessed by using native chemical ligation to couple two peptides together with quantitative yields.

Peptide analogs: As used herein, unless indicated otherwise or contradictory in context, the term "peptide analogs" refers to polypeptide variants which differ by one or more amino acid alterations, e.g., substitutions, additions or deletions of amino acid residues that still maintain one or more of the properties of the parent or starting peptide.

In one particular example, a peptidomimetic is a hybrid molecule containing both, at least one peptide, and at least one of a polysaccharide, a polynucleotide or a linear or branched, saturated or unsaturated, hydrocarbon chain.

Linear peptide: As used herein, unless indicated otherwise or contradictory in context, the term "linear peptide" means a peptide in which the C-terminal and the N-terminal amino acid residues do not covalently interact with each other and none of the C-terminal or the N-terminal amino acid residues covalently interacts with another amino acid residue of the peptide chain.

Cyclic peptide: As used herein, unless indicated otherwise or contradictory in context, the term "cyclic peptide" means peptide in which the C-terminal and N-terminal amino acid residues do covalently interact with each other or the C-terminal and/or the N-terminal amino acid residues covalently interact with at least one other amino acid residue of the peptide chain so as to form a ring-like structure. Amino acid: As used herein, unless indicated otherwise or contradictory in context, the term "amino acid" refers to naturally occurring and non-naturally occurring amino acids including amino acid analogs.

Synthetic peptide: As used herein, unless indicated otherwise or contradictory in context, the terms "synthetic peptide" or "non-natural peptide" means a peptide which may not be found in nature without human direct intervention (except for its extraction and/or isolation). For example, in certain embodiments, a synthetic peptide may have the amino acid sequence of a natural peptide except for at least one amino acid deletion or substitution relative to the natural sequence. In the case of a substitution, an amino acid from the natural sequence is replaced by another, different, naturally-occurring or non- naturally occurring amino acid. For example, in certain embodiments, a synthetic peptide may not possess a post-translational modification of the natural peptide such as the attachment of an acetate group, a phosphate group, a lipid, a carbohydrate, or the formation of a disulfide bridge.

Examples of such interactions are σ-bonding and π-bonding.

Non-covalent interaction: As used herein, unless indicated otherwise or contradictory in context, the term "interact non-covalently", "non-covalent interaction" or "non-covalent bond" are interchangeably used and means a chemical bond or interaction that does not involve the sharing of electron pairs between atoms but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. Non-covalent interactions can be generally classified into four categories, electrostatic interactions, π-interactions, van der Waals forces, and hydrophobic interactions.

Electrophile: As used herein, unless indicated otherwise or contradictory in context, the term "electrophile" means an organic molecule attracted to electrons that participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile. Most electrophiles are positively charged, have an atom that carries a partial positive charge, or have an atom that does not have an octet of electrons. Nucleophile: As used herein, unless indicated otherwise or contradictory in context, the term "nucleophile" means an organic molecule that donates an electron pair to an electrophile to form a chemical bond in relation to a reaction. All molecules or ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Polysaccharide: As used herein, unless indicated otherwise or contradictory in context, the term "polysaccharide" means polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and which upon hydrolysis provide monosaccharides or oligosaccharides. They range in structure from linear to highly branched polymers.

Antibody: As used herein, unless indicated otherwise or contradictory in context, the term "antibody" encompasses the various forms of antibodies including, but not limited to, whole antibodies, human antibodies, humanized antibodies and genetically engineered antibodies like monoclonal antibodies, chimeric antibodies or recombinant antibodies as well as fragments of such antibodies as long as the characteristic properties according to the present disclosure are retained.

Monoclonal antibody: As used herein, unless indicated otherwise or contradictory in context, the term "monoclonal antibody" refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific, being directed against a single antigenic site. Furthermore, in contrast to polyclonal antibody preparations which include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. In addition to their specificity, the monoclonal antibodies are advantageous in that they may be synthesized uncontaminated by other antibodies. The modifier "monoclonal" is not to be construed as requiring production of the antibody by any particular method. For example, the monoclonal antibodies useful in the present invention may be prepared by the hybridoma methodology described by Kohler et al., Nature, 256:495 (1975), or may be made using recombinant DNA methods in bacterial, eukaryotic animal or plant cells (such as in U.S. Pat. No. 4,816,567). The "monoclonal antibodies" may also be isolated from phage antibody libraries using the techniques described in Clackson et al. , Nature, 352:624-628 (1991 ) and Marks et al. , J. Mol. Biol., 222:581 -597 (1991 ), for example. All previously cited references being hereby incorporated by reference in their entirety.

Chimeric antibody: As used herein, unless indicated otherwise or contradictory in context, the term "chimeric antibody" refers to a monoclonal antibody comprising a variable region, i.e., binding region, from one source or species and at least a portion of a constant region derived from a different source or species, usually prepared by recombinant DNA techniques. Chimeric antibodies comprising a murine variable region and a human constant region are especially preferred. Such murine/human chimeric antibodies are the product of expressed immunoglobulin genes comprising DNA segments encoding murine immunoglobulin variable regions and DNA segments encoding human immunoglobulin constant regions. Other forms of "chimeric antibodies" encompassed by the present invention are those in which the class or subclass has been modified or changed from that of the original antibody. Such "chimeric" antibodies are also referred to as "class-switched antibodies." Methods for producing chimeric antibodies involve conventional recombinant DNA and gene transfection techniques now well known in the art such as in Morrison, S. L, et al. , Proc. Natl. Acad. Sci. USA 81 (1984) 6851-6855 and U.S. Patent No. 5,204,244, which are hereby incorporated by reference in their entirety.

Humanized antibody: As used herein, unless indicated otherwise or contradictory in context, the term "humanized antibody" refers to antibodies in which the framework or "complementarity determining regions" (CDR) have been modified to comprise the CDR of an immunoglobulin of different specificity as compared to that of the parent immunoglobulin.

Human antibody: As used herein, unless indicated otherwise or contradictory in context, the term "human antibody" includes antibodies having variable and constant regions derived from human germline immunoglobulin sequences. Based on this technology, human antibodies against a great variety of targets can be produced. Examples of human antibodies are for example described in Kellermann, S. A., et al., Curr Opin Biotechnol. 13 (2002) 593-597, which is hereby incorporated by reference in its entirety.

Recombinant human antibody: As used herein, unless indicated otherwise or contradictory in context, the term "recombinant human antibody" includes all human antibodies that are prepared, expressed, created or isolated by recombinant means, such as antibodies isolated from a host cell such as a NSO or CHO cell or from an animal (e.g. a mouse) that is transgenic for human immunoglobulin genes or antibodies expressed using a recombinant expression vector transfected into a host cell. Such recombinant human antibodies have variable and constant regions derived from human germline immunoglobulin sequences in a rearranged form. Antigen: As used herein, unless indicated otherwise or contradictory in context, the term "antigen" is a predetermined antigen to which an antibody can selectively bind. The target antigen may be polypeptide, carbohydrate, nucleic acid, lipid, hapten or other naturally occurring or synthetic compound. Preferably, the target antigen is a polypeptide of the transmembrane receptor family such as integrins, syndecans, selectins or dystroglycans. An antibody "which binds" an antigen of interest, e.g. an integrin expressed on the surface of a neoplastic cell, is one that binds the antigen with sufficient affinity such that the antibody is useful as a therapeutic agent in targeting a cell or tissue expressing the antigen, and does not significantly cross-react with other proteins. In such embodiments, the extent of binding of the antibody to a "non-target" protein will be less than about 10% of the binding of the antibody to its particular target protein as determined by fluorescence activated cell sorting (FACS) analysis or radioimmunoprecipitation (RIA). With regard to the binding of an antibody to a target molecule, the term "specific binding" or "specifically binds to" or is "specific for" a particular polypeptide or an epitope on a particular polypeptide target means binding that is measurably different from a non-specific interaction. Specific binding can be measured, for example, by determining binding of a molecule compared to binding of a control molecule, which generally is a molecule of similar structure that does not have binding activity. For example, specific binding can be determined by competition with a control molecule that is similar to the target, for example, an excess of non-labeled target. In this case, specific binding is indicated if the binding of the labeled target to a probe is competitively inhibited by excess unlabeled target. The term "specific binding" or "specifically binds to" or is "specific for" a particular polypeptide or an epitope on a particular polypeptide target as used herein can be exhibited, for example, by a molecule having a Kd for the target of at least about 10 ^"4 M, alternatively at least about 10 ^~5 M, alternatively at least about 10 ^~6 M, alternatively at least about 10 ^~7 M, alternatively at least about 10 ^~8 M, alternatively at least about 10 ^~9 M, alternatively at least about 10 ^~10 M, alternatively at least about 10 ^~11 M, alternatively at least about 10 ^~12 M, or greater. In one embodiment, the term "specific binding" refers to binding where a molecule binds to a particular polypeptide or epitope on a particular polypeptide without substantially binding to any other polypeptide or polypeptide epitope.

Constant domains: As used herein, unless indicated otherwise or contradictory in context, the term "constant domains" refers to domains that are not involved directly in binding the antibody to an antigen but are involved in the effector functions (ADCC, complement binding, and CDC).

Variable region: As used herein, unless indicated otherwise or contradictory in context, the term "variable region" (variable region of a light chain (VL), variable region of a heavy chain (VH)) refers to each of the pair of light and heavy chains which is involved directly in binding the antibody to the antigen. The domains of variable human light and heavy chains have the same general structure and each domain comprises four framework (FR) regions whose sequences are widely conserved, connected by three "hypervariable regions" (or complementarity determining regions, CDRs). The framework regions adopt a b-sheet conformation and the CDRs may form loops connecting the b-sheet structure. The CDRs in each chain are held in their three-dimensional structure by the framework regions and form together with the CDRs from the other chain the antigen binding site.

Hypervariable region: As used herein, unless indicated otherwise or contradictory in context, the term "hypervariable region" or "antigen-binding portion of an antibody" refers to the amino acid residues of an antibody which are responsible for antigen-binding. The hypervariable region comprises amino acid residues from the "complementarity determining regions" or "CDRs". "Framework" or "FR" regions are those variable domain regions other than the hypervariable region residues as herein defined. Therefore, the light and heavy chains of an antibody comprise from N- to C-terminus the domains FR1 , CDR1 , FR2, CDR2, FR3, CDR3, and FR4. Especially, CDR3 of the heavy chain is the region which contributes most to antigen binding. CDR and FR regions are determined according to the standard definition of Kabat, et al., Sequences of Proteins of Immunological Interest, 5th ed., Public Health Service, National Institutes of Health, Bethesda, Md. (1991 ), and/or those residues from a "hypervariable loop". Biocompatible: As used herein, unless indicated otherwise or contradictory in context, the term "biocompatible" means compatible with living cells, tissues, organs or systems posing little to no risk of injury, toxicity or rejection by the immune system.

Biologically active: As used herein , unless indicated otherwise or contradictory in context, the term "biologically active" refers to a characteristic of any substance that has activity in a biological system and/or organism. For instance, a substance that, when administered to an organism, has a biological effect on that organism, is considered to be biologically active. In particular examples, a compound, substance or pharmaceutical composition of the present disclosure may be considered biologically active even if a portion of the compound, substance or pharmaceutical composition is biologically active or mimics an activity considered biologically relevant.

Stem cells: As used herein, unless indicated otherwise or contradictory in context, the term "stem cell" refers to the term as it is generally understood in the art. For example, in certain embodiments, stem cells, regardless of their source, are cells that are capable of dividing and renewing themselves for long periods, are at least to a degree unspecialized (undifferentiated), and can give rise to (differentiate into) specialized cell types (i.e., they are progenitor or precursor cells for a variety of different, specialized cell types).

Mesenchymal stem cells: As used herein, unless indicated otherwise or contradictory in context, the term "mesenchymal stem cells" generally means multipotent adult stromal cells that can differentiate into a variety of cell types, such as osteoblasts, chondrocytes, and adipocytes.

Stem cell-like: As used herein, unless indicated otherwise or contradictory in context, the term "Stem cell-like" refers to a cell which is not a stem cell by its origin but functions as a stem cell and presents similar characteristics such as, for example, the expression of stemness markers like Stro-1 and/or is multipotent thus has the ability to differentiate into various cell types. Progenitor cells: As used herein, unless indicated otherwise or contradictory in context, the term "progenitor cells" generally means a biological cell that, like any stem cell, has a tendency to differentiate into a specific type of cell, but is already more specific than a stem cell and is pushed to differentiate into its "target" cell. Stem cells can generally replicate indefinitely, whereas progenitor cells can divide only a limited number of times.

Adult stem cells: As used herein, unless indicated otherwise or contradictory in context, the term "adult stem cells" means undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in juvenile as well as adult animals and human bodies.

Differentiation: As used herein, unless indicated otherwise or contradictory in context, the term "differentiation" refers to the process by which a less specialized cell becomes a more specialized cell type and involves a switch from one gene expression pattern to another.

Differentiated cells: As used herein, unless indicated otherwise or contradictory in context, the term "differentiated cells" generally means any cell of a specific lineage at the exception of cells containing stem cell specific markers. Non-terminally differentiated: As used herein, unless indicated otherwise or contradictory in context, the term "non-terminally differentiated", when used in relation to a cell, refers to a differentiated cell as defined herein which has not reached its final state of differentiation. For example, in certain embodiments, in the Osteoblast cell lineage, a non-terminally differentiated cell is any differentiated cell of the lineage at the exception of an osteocyte.

Terminally differentiated: As used herein, unless indicated otherwise or contradictory in context, the term "terminally differentiated", when used in relation to a cell, refers to a differentiated cell as defined herein which has reached its final state of differentiation. For example, in certain embodiments, in the Osteoblast cell lineage, a terminally differentiated cell is an osteocyte.

Methods for obtaining stem cells: Methods for obtaining such stem cells and providing initial culture conditions, such as a liquid culture or semi-solid culture medium, are known in the art. The cells are initially expanded in vivo or in vitro, by contacting the source of the stem cells with a suitable reagent that expands or enriches such cells in the tissue source or in culture. Preferably, adult stem cells are isolated from a tissue source and then expanded or enriched in vitro by exposure to a suitable agent. Cells are obtained from an individual by any suitable method for obtaining a cell sample from an animal, including, but not limited, to, collection of bone marrow collection of a bodily fluid (e.g., blood), collection of umbilical cord blood, tissue punch, and tissue dissection, including particularly, but not limited to, any biopsies of skin, intestine, cornea, spinal cord, brain tissue, scalp, stomach, breast, lung (e.g. , including lavage and bronchioschopy), fine needle aspirates of the bone marrow, amniotic fluid, placenta and yolk sac.

Cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "cell lineage" refers to the developmental history of a particular cell from its primary state in the fertilized egg or embryo through to its fully differentiated state. The different steps and phases involved in the development of a cell produces many intermediate cells which may be referred to as progenitor or precursor cells in the present application and form an integral part of the cell lineage.

Bone: It is conventionally known that mature osteoblasts are the cells responsible for bone formation and are derived from osteoblast precursors. Differentiation of human bone marrow mesenchymal stem cells and osteoblast precursors is one of the important processes for bone regeneration. Osteoblasts differentiate from mesenchymal stem cells. Mature osteoblasts differentiate from osteoblast precursors and into osteocytes which are non-dividing cells. Bone-related neoplastic diseases include, but are not limited to, bone primary tumors (benign tumors or cancers) such as osteoma, osteoid osteoma, osteochondroma, osteoblastoma, enchondroma, giant cell tumor of bone, aneurysmal bone cyst, fibrous dysplasia of bone, osteosarcoma, chondrosarcoma, Ewing's sarcoma, fibrosarcoma; and secondary tumors (i.e. metastasize) such as, for example, in certain embodiments, carcinomas of the prostate, breasts, lungs, thyroid, and kidneys.

Osteoblast cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "osteoblast cell lineage" refers to bone cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, osteoblasts, osteocytes or any precursors thereof.

Cartilage: Native chondrocytes are responsible for the synthesis and turnover of the cartilage extracellular matrix (ECM), which provides an environment of nutrition diffusion for chondrocytes and provides the joint surface with biomechanical competence. Chondrogenic cells arise from pluripotential adult mesenchymal stem cells (MSCs) through a series of differentiation pathways. Chondrogenic differentiation of MSCs is induced by various intrinsic and extrinsic factors. Growth factors play an important role in this process. For instance, in the hyaline cartilage, growth factors regulate homeostasis and integrity, as well as development. Cartilage-related neoplastic diseases include, but are not limited to, Chondroma/ecchondroma/enchondroma (Enchondromatosis, Extraskeletal chondroma), Chondrosarcoma (Mesenchymal chondrosarcoma, Myxoid chondrosarcoma), Osteochondroma (Osteochondromatosis), Chondromyxoid fibroma, and Chondroblastoma,

Chondrocytic cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "chondrocytic cell lineage" refers to cartilage cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, chondroblasts, chondrocytes or any precursors thereof.

Muscles: Skeletal muscle is a highly complex and heterogeneous tissue serving a multitude of functions in the organism. The process of generating muscle - myogenesis - can be divided into several distinct phases. During embryonic myogenesis, mesoderm-derived structures generate the first muscle fibers of the body proper, and in subsequent waves additional fibers are generated along these template fibers. In the perinatal phase, muscle resident myogenic progenitors initially proliferate extensively but, later on, decrease as the number of myonuclei reaches a steady state and myofibrillar protein synthesis peaks. Once the muscle has matured, these progenitors will enter quiescence and henceforth reside within it as satellite cells. Adult skeletal muscle, like all renewing organs, relies on a mechanism that compensates for the turnover of terminally differentiated cells to maintain tissue homeostasis. This type of myogenesis depends on the activation of satellite cells that have the potential to differentiate into new fibers. The most comprehensively studied form of myogenesis takes place when mature muscle is damaged and large cohorts of satellite cells expand mitotically and differentiate to repair the tissue and reestablish homeostasis. It is now generally accepted that satellite cells are closely related to progenitors of somitic origin. The activation of the network of transcription factors that controls skeletal muscle development depends on paracrine factors that are released by adjacent tissues, such as the neural tube, notochord, surface ectoderm and lateral mesoderm. Several secreted factors have been identified that determine the spatial and temporal onset of myogenesis. Signalling molecules, such as Noggin and bone morphogenetic proteins (BMPs) - which inactivate and activate receptors of the transforming growth factor-β (TGF ) superfamily, respectively - are reported to participate in the orchestration of the activation of myogenesis. Muscle-related neoplastic diseases include, but are not limited to, Rhabdomyosarcoma, and Leiomyosarcoma.

Muscle cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "muscle cell lineage" refers to muscle cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, myoblasts, myocytes or any precursors thereof.

Vascular: The vasculature in the human body forms through two distinct processes: vasculogenesis and angiogenesis. Vasculogenesis is defined as the process of de novo blood vessel formation occurring when endothelial precursor cells (angioblasts) migrate and differentiate into endothelial cells which form the new vessel. These vascular trees are then extended through angiogenesis which is defined as the new vessel formation secondary to proliferation of endothelial cells from pre-existing vessels. Vasculogenesis as well as angiogenesis occur during the embryologic development of the circulatory system but also in the adult organism from circulating endothelial progenitor cells (derivatives of stem cells) able to contribute, albeit to varying degrees, to neovascularization. Vascular-related neoplastic diseases include, but are not limited to, Hemangiosarcoma, Kaposi's sarcoma, Lymphangiosarcoma, and Infantile hemangio-pericytoma.

Vascular cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "vascular cell lineage" refers to vascular cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, angioblast, pericytes and endothelial cells or any precursors thereof.

Neurons: It was recently reported that neural cells can be regenerated from neural stem cells (NSCs). These are self-renewing, multipotent adult stem cells that generate the main phenotype of the nervous system. They undergo asymmetric cell division into two daughter cells, one non-specialized and one specialized. NSCs primarily differentiate into neurons, astrocytes, and oligodendrocytes. NSCs are generated throughout an adult's life via the process of neurogenesis. NSCs can be differentiated to replace lost or injured neurons or in many cases even glial cells. NSCs are stimulated to begin differentiation via exogenous cues from their microenvironment, or the neural stem cell niche. This niche defines a zone in which stem cells are retained after embryonic development for the production of new cells of the nervous system. This continual supply of new neurons and glia then provides the postnatal and adult brain with an added capacity for cellular plasticity. Critical to the maintenance of the stem cell niche are microenvironmental cues and cell-cell interactions that act to balance stem cell quiescence with proliferation and to direct neurogenesis versus gliogenesis lineage decisions. Several proteins like different growth factors are involved in the mechanisms of the neural stem cell niche as well as in the maintenance and growth of the newly formed neurons. These include the BMPs, FGFs, PDGF, VEGF, TGF β, BDNF and others. Neuron-related neoplastic diseases include, but are not limited to, Anaplastic astrocytoma, Astrocytoma, Central neurocytoma, Choroid plexus carcinoma, Choroid plexus papilloma, Choroid plexus tumor, Dysembryoplastic neuroepithelial tumour, Ependymal tumor, Fibrillary astrocytoma, Giant-cell glioblastoma, Glioblastoma multiforme, Gliomatosis cerebri, Gliosarcoma, Hemangiopericytoma, Medulloblastoma, Medulloepithelioma, Meningeal carcinomatosis, Neuroblastoma, Neurocytoma, Oligoastrocytoma, Oligodendroglioma, Optic nerve sheath meningioma, Pediatric ependymoma, Pilocytic astrocytoma, Pinealoblastoma, Pineocytoma, Pleomorphic anaplastic neuroblastoma, Pleomorphic xanthoastrocytoma, Primary central nervous system lymphoma, Sphenoid wing meningioma, Subependymal giant cell astrocytoma, Subependymoma, and Trilateral retinoblastoma.

Eye retina: The vertebrate retina is a light-sensitive layer of tissue, lining the inner surface of the eye. Retinal development involves a complex progression of tissue induction, proliferation of retinal progenitor cell (RPC) populations and terminal differentiation of these cells into specific functional types. Bone morphogenetic protein (BMP), is a member of the transforming growth factor (TGF)^ family of signaling molecules plays an important role in the retinal cell development. BMP-2, -4, and -7 and their receptors (BMPRs) are expressed in the eye during embryogenesis and are essential for multiple aspects of retinal development. Retina-related neoplastic diseases include, but are not limited to, Retinoblastoma. It should also be noted that eye cancers can be primary (starts within the eye) and metastatic (spread to the eye from another organ). The two most common cancers that would spread to the eyes from another organ are breast cancer and lung cancer. Other, less common, sites of origin include prostate, kidney, thyroid, skin, colon and blood or bone marrow.

Retinal cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "retinal cell lineage" refers to eye retina cells at any stage of their development and thus include, but are not limited to, photoreceptor, bipolar cells, rod and cone cells or any precursors thereof. Kidneys: The kidneys are composed of complex tissues consisting of several different cell types including glomerular podocytes, endothelial cells, mesangial cells, interstitial cells, tubular epithelial cells, and connecting duct cells. These cell types interact to establish a precise cellular environment that functions as an efficient tissue. Kidneys-related neoplastic diseases include, but are not limited to, Squamous cell carcinoma, Juxtaglomerular cell, tumor (reninoma), Angiomyolipoma, Renal oncocytoma, Bellini duct carcinoma, Clear-cell sarcoma of the kidney, Mesoblastic nephroma, Wilms' tumor, Mixed epithelial stromal tumor, Clear cell adenocarcinoma, Transitional cell carcinoma, Inverted papilloma, Renal lymphoma, Teratoma, Carcinosarcoma, and Carcinoid tumor.

Renal cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "renal cell lineage" refers to renal cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, podocytes, or any precursors thereof.

Ligaments and Tendons: Tendons and ligaments (T/L) are dense connective tissues of mesodermal origin. They connect and transmit force from muscle to bone and bone to bone, respectively. Both tissues are able to store elastic energy and withstand hightensile forces, on which locomotion is entirely dependent. T/L are predominantly composed of collagen type I fibrils organized in a highly hierarchical manner that is unique for the T/L. Other collagens (types lll-VI, XI, XII, XIV, and XV) and various proteoglycans (decorin, cartilage oligomeric matrix protein (COMP), byglican, lumican, fibromodulin, tenascin-C, etc.) are building the remaining T/L substance. The cellular content of T/L is dominated by tendon-specific fibroblasts named tenocytes. During embryonic development, the tendon-specific cells descend from a sub-set of mesenchymal progenitors condensed in the syndetome, a dorsolateral domain of the sclerotome. L/T-related neoplastic diseases include, but are not limited to, Fibrosarcoma, Malignant fibrous, Hystiocytoma, and Dermatofibrosarcoma.

Ligament and tendon cell lineage: As used herein, unless indicated otherwise or contradictory in context, the term "ligament and tendon cell lineage" or "L/T cell lineage" refers to bone or cartilage cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, fibroblasts, fibrocytes, or any precursors thereof.

Skin: The skin constantly renews itself throughout adult life. Stem cells (SCs) residing in the epidermis ensure the maintenance of adult skin homeostasis, but they also participate in the repair of the epidermis after injuries. The skin protects the body from dehydration, injury and infection. The skin consists of an underlying dermis, separated by a basement membrane from the multilayered overlaying epidermis. The dermis is of mesodermal embryonic origin and contains as adult stem cells fibroblastic mesenchymal stem-cell-like cells. These cells have a multi-lineage differentiation potential, being also able to form adipose tissue or bones. Skin-related neoplastic diseases include, but are not limited to, basal cell carcinoma, squamous cell carcinoma, malignant melanoma, dermatofibrosarcoma protuberans, Merkel cell carcinoma, Kaposi's sarcoma, keratoacanthoma, spindle cell tumors, sebaceous carcinomas, microcystic adnexal carcinoma, Paget's disease of the breast, atypical fibroxanthoma, leiomyosarcoma, and angiosarcoma. Fibroblast lineage: As used herein, unless indicated otherwise or contradictory in context, the term "fibroblast lineage" refers to skin cells at any stage of their development and thus include, but are not limited to, mesenchymal stem cells, fibroblasts, keratinocytes, Merkel cells, melanocytes, Langerhans cells, and any precursor cells thereof.

Reproduction: Reproduction (or procreation) is the biological process by which new offspring individual organisms are produced from their parents. Sexual reproduction is a biological process by which organisms create descendants that have a combination of genetic material contributed from two (usually) different members of the species. The development and physiological functions of basic structures in the mammalian reproductive system are influenced by the tissue-specific expression of members of different growth factors families like the BMP family. The establishment of the germ line is a fundamental aspect of reproduction. Germ cell determination is induced in epiblast cells by the extraembryonic ectoderm, and is not acquired through the inheritance of preformed germ plasma. There is some strong evidence that BMP-4 and -8b play a central role in determining primordial germ cell (PGC) formation in the embryo. The genes encoding BMP-4 and -8b have overlapping expression in the extraembryonic ectoderm before gastrulation, i.e., before PGCs are seen. Thus, PGC formation requires BMP-4 expression. There is also evidence from knockout mammals that BMP-8b is required for PGC formation. Furthermore, there is increasing evidence that locally produced BMPs play a major role in the differentiation of the pituitary gonadotrope. Reproduction-related neoplastic diseases include, but are not limited to, Prostate cancer, Ovary cancer (adenocarcinoma, or glandular cancer) also known as carcinoma of the prostate or prostatic intraepithelial neoplasia. Reproduction system lineage: As used herein, unless indicated otherwise or contradictory in context, the term "reproduction system lineage" refers to Sertoli cells, Leydig cell and Germ cell at any stage of their development, in particular, mesenchymal stem cells.

Blood: Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those cells. When it reaches the lungs, gas exchange occurs wherein carbon dioxide is diffused out of the blood into the alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the bicuspid valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. Hematopoietic stem cells (HSCs) are the blood cells that give rise to all the other blood cells and are derived from the mesoderm. They are located in the red bone marrow, which is contained in the core of most bones. The HSCs give rise to the myeloid lineage (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic cells), and to the lymphoid lineages (T-cells, B-cells, NK-cells). The most abundant cells in the vertebrate blood are red blood cells (also called RBSs or erythrocytes). These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. Blood-related neoplastic diseases include, but are not limited to, acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML).

Blood cell lineages (myeloid lineage and lymphoid lineage): As used herein, unless indicated otherwise or contradictory in context, the term "blood cell lineages" refers to blood cells at any stage of their development from the myeloid or from the lymphoid lineage, and thus include, but are not limited to, hematopoietic stem cells (HSC), myeloid progenitors, lymphoid progenitors, mast cells, myeloblasts, monocytes, macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes, thrombocytes, dendritic cells, small lymphocytes, T-lymphocytes (T-cells), B-lymphocytes (B-cells), natural killer (NK)-cells, and any precursor cells thereof.

Adipose tissue: Adipose tissue is loose connective tissue composed mostly of adipocytes. In addition to adipocytes, adipose tissue contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells (i.e. adipose tissue macrophages (ATMs)). Adipose tissue is derived from preadipocytes. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. Pre-adipocytes are thought to be undifferentiated fibroblasts that can be stimulated to form adipocytes. The pre-adipocytes originate from mesenchymal stem cells. Areolar connective tissue is composed of adipocytes. The term "Npoblast" is used to describe the precursor of the adult cell. The term "Mpoblastoma" is used to describe a tumor of this cell type. Adipose tissue-related neoplastic diseases include, but are not limited to, lipoma, Adenolipomas, Angiolipoleiomyomas, Angiolipomas, Corpus callosum lipoma, Cerebellar pontine angle and internal auditory canal lipomas, Chondroid lipomas, Hibernomas, Intradermal spindle cell lipomas, Neural fibrolipomas, Pleomorphic lipomas, Spindle-cell lipomas, Superficial subcutaneous lipomas, Lipoblastoma, Liposarcoma.

Digestive system: The human digestive system is composed mainly of the gastrointestinal tract (including the esophagus, stomach, small intestine, large intestine, rectum and anus) and the accessory digestive glands (the liver, the gall bladder and the pancreas). To achieve the goal of providing energy and nutrients to the body, six major functions take place in the digestive system: ingestion, secretion, mixing and movement, digestion, absorption, excretion. The gastrointestinal wall refers to the specialized series of tissue layers surrounding the lumen of the gastrointestinal tract. The general structure involves the four following layers (ordered from the lumen outward): mucosa, submucosa, muscularis externa, serosa (if the tissue is intraperitoneal) / adventitia (if the tissue is retroperitoneal). Gastrointestinal cancer refers to malignant conditions of the gastrointestinal tract (Gl tract) and accessory organs of digestion. The symptoms relate to the organ affected and can include obstruction (leading to difficulty swallowing or defecating), abnormal bleeding or other associated problems. Gastrointestinal tissue-related neoplastic diseases include, but are not limited to, Esophageal cancer, Stomach cancer, Pancreatic cancer, Liver cancer, Gallbladder cancer, MALT lymphoma, Gastrointestinal stromal tumors and Cancers of the biliary tree, including cholangiocarcinoma.

Gastrointestinal cell lineages: As used herein, unless indicated otherwise or contradictory in context, the term " gastrointestinal cell lineages" refers to gastrointestinal cells and cells of the digestive accessory organs at any stage of their development and thus include, but are not limited to interstitial cells of Cajal, gastrointestinal epithelial cells, parietal cells, acinar cells, chief cells, mucus cells, goblet cells, G cells, endocrine I cells, endocrine S cells, endocrine K cells, endocrine M cells, ECL (enterochromaffin) cells, D cells, enteroendocrine cells, APUD cells, hepatocytes, sinusoidal hepatic endothelial cells, Kupffer cells, hepatic stellate cells, centroacinar cells, pancreatic stellate cells, a-cells, γ-cells, β-cells, δ-cells, centroacinar cells, basophilic cells, ductal cells, columnar cells, cholecystocytes and any precursor cells thereof.

Lung: The lung is the essential respiration organ in many air-breathing animals. In mammals the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. A large surface area is needed for this exchange of gases, which is accomplished by the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli. Lung cells include, but are not limited to, type I pneumocytes, type II pneumocytes, clara cells and goblet cells. Lung tissue-related neoplastic diseases include, but are not limited to, lung cancer also known as carcinoma of the lung or pulmonary carcinoma, Epithelial cells or small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC).

Head and neck cancer: As used herein, unless indicated otherwise or contradictory in context, the term "head and neck cancer" refers to a group of cancers that usually starts in the lip, oral cavity, nasal cavity, paranasal sinuses, pharynx, and larynx. About 90% of head and neck cancers are squamous cell carcinomas. Thus, neoplastic diseases such as head and neck cancers include, but are not limited to, oral cancer, nasopharynx cancer, oropharyngeal cancer, hypopharynx cancer and laryngeal cancer.

The cell lineage involved in head and neck cancers includes all the cells involved in the formation of such cancers at any stage of their development and thus include, but are not limited to, cells of the oral cavity, cells of the pharynx, cells of the larynx, cells of the paranasal sinuses and nasal cavity, cells of the salivary glands and any precursor cells thereof.

Ratio: As used herein, unless indicated otherwise or contradictory in context, the term "ratio", when used in relation to GFR-binding compound with respect to the adhesion protein inhibitor in the pharmaceutical association or composition disclosed herein, refers to the (molar, weight or part as specified) ratio between the quantity of GFR-binding compound and the quantity of adhesion protein inhibitor. The ratio may be a molar ratio, a weight ratio or a part ratio and will be specified as needed on a case by case basis. Quantity units may conventionally be mole, millimole, gram, milligram or parts. For example, in certain embodiments, it is convenient to express the relative quantity between GFR-binding compounds and adhesion protein inhibitors using densities. It shall be understood that this ratio may be varied according to the neoplastic cell type to be treated.

Density: As used herein, unless indicated otherwise or contradictory in context, the term "density", when used in relation to GFR-binding compound with respect to the adhesion protein inhibitor in the pharmaceutical composition disclosed herein, refers to the quantity of GFR-binding compounds, expressed in e.g. mole, millimole, gram, or milligram, with respect to one standardised surface unit e.g. squared millimetre (mm ² ), squared micrometre (μm ² ), or squared nanometre (nm ² )). For example, in certain embodiments, the ratio between a GFR-binding compound and an adhesion protein inhibitor in the pharmaceutical association or composition disclosed herein may be expressed in pmol per mm ² or pmol/mm ² . Cell cycle: As used herein, unless indicated otherwise or contradictory in context, the term "cell cycle" refers to the process through which a vertebrate cell self-replicate. In eukaryote cells, cell cycle consists of four discrete phases: G1 , S, G2, and M. Together, the G1 , S, and G2 phases make up the period known as interphase. During the S or "synthesis" phase, the cell replicates its DNA creating an exact copy of all of its chromosomes. In the M or "mitotic" phase, the cell division actually occurs and separates the chromosomes in its cell nucleus into two identical sets in two nuclei. The first phase within interphase, from the end of the previous M phase until the beginning of DNA synthesis, is called G1 . During this phase the biosynthetic activities of the cell, which are considerably slowed down during M phase, resume at a high rate. This phase is marked by the formation of millions of proteins and later on enzymes that are required in S phase, mainly those needed for DNA replication. The G2 phase, or pre-mitotic phase, is the third and final sub-phase of Interphase in the cell cycle directly preceding Mitosis. It follows the successful completion of S phase and ends with the onset of prophase, the first phase of mitosis. In order to move from one phase of the cell cycle to the next, a cell must "validate" numerous checkpoints. At each checkpoint, specialized proteins determine whether the necessary conditions exist. If so, the cell is free to enter into the next phase. If not, progression through the cell cycle is halted. For example, in certain embodiments, during G1 , the cell passes through a "validation" window punctuated by the restriction point R. During the "validation" phase, different checkpoints ensure that environmental conditions are favourable for replication. If conditions are not favourable, the cell may enter a resting state known as GO. The GO phase or resting phase is a period in the cell cycle in which cells exist in a quiescent state. GO phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle. Typically, a healthy vertebrate cell undergoes cell division when needed e.g. to regenerate damaged tissues or simply replace old tissues by new ones, by switching from a GO resting state into the G1 state of the cell cycle and resume cell division. In contrast, neoplastic cells (such as cancer cells) have lost their ability to suspend cell division and switch to the GO phase therefore undergoing permanent cell division which is generally referred to uncontrolled cell division or proliferation. Another "validation" window takes place later in the cell cycle, just before a cell moves from G2 to mitosis. Here, a number of proteins scrutinize the cell's DNA ensuring proper replication has taken place. Finally, another cell cycle "validation" window takes place during mitosis in which different checkpoints determines whether chromosomes are correctly attached to the spindle, and to the network of microtubules that will separate them during cell division.

Quiescence: As used herein, unless indicated otherwise or contradictory in context, the term "quiescence", when used in relation to a cell, refers to a resting state during which the cell does not divide, duplicate or proliferate. This state is also called the GO state. As used herein, "inducing quiescence of a neoplastic cell" thus means to provoke the passage from G1 to GO of a neoplastic cell which usually has lost the ability to do so. One method to detect the passage from G1 to GO is, for instance, to monitor the state of phosphorylation of the protein Rb via Western Blot. The Rb protein is normally not phosphorylated during the GO phase but becomes phosphorylated or even hyper- phosphorylated during the rest of the cell cycle. Consequently, observing the absence (or substantial reduction i.e. at least 90% reduction, in comparison with the quantity present in the G1 phase) of phosphorylated Rb protein on a western blot confirms that a neoplastic cell has undergone (at some point in time) a switch to the GO phase.

Cell division or cell proliferation: As used herein, unless indicated otherwise or contradictory in context, the term "cell division" or "cell proliferation", refers to the process by which a cell self-replicate, replicate or is caused to replicate. Proliferate: As used herein, unless indicated otherwise or contradictory in context, the term "proliferate" means to grow, expand or increase or cause to grow, expand or increase. "Proliferative" means having the ability to proliferate. "Anti-prol iterative" means having properties to counter, reduce, or inhibit proliferation. Hyperproliferation: As used herein, unless indicated otherwise or contradictory in context, the term "hyperproliferation" or "uncontrolled proliferation" means the abnormal growth, expansion or increase or causing the abnormal growth, expansion or increase. Abnormal growth typically originates from the abnormal regulation of the cell cycle preventing the cell to reach the GO state and stop cell division and replication. One consequence of hyper or uncontrolled proliferation is the development of neoplastic diseases such as tumours and cancers.

Hyperproliferative diseases: As used herein, unless indicated otherwise or contradictory in context, the term "hyperproliferative diseases" is used interchangeably with "neoplastic diseases" and refers to diseases that are characterized by uncontrolled cellular proliferation and/or disruption in programmed cell death. The loss of a cell's ability to control cellular proliferation is often caused by genetic damage to the cellular pathways responsible for regulating cellular functions, including but not limited to, for example, in certain embodiments, metabolism, cell cycle progression, cell adhesion, vascular function, apoptosis, and angiogenesis. Anti-mitogen activity: As used herein, unless indicated otherwise or contradictory in context, the term "anti-mitogen activity", refers to biological pathways that down-regulate, partially inhibit or suppress cell mitosis i.e. cell division. As used herein, a substance or pharmaceutical association which promotes, induces or favours anti-mitogen activity thus means a substance or pharmaceutical association which provides at least part of its effective biologic or therapeutic action by down-regulating, partially inhibiting or suppressing mitosis of the neoplastic cell to be treated. Tumor suppressor pathways: As used herein, unless indicated otherwise or contradictory in context, the term "tumor suppressor pathways" refers to biological pathways that down-regulate, partially inhibit or suppress tumor activity i.e. protect the cell against cell defects which could cause tumors or cancers. As used herein, a substance or pharmaceutical association which promotes, induces or favours tumor suppressor pathways thus means a substance or pharmaceutical association which provides at least part of its effective biologic or therapeutic action by up-regulating, activating or promoting the tumor suppressor genes or proteins of the neoplastic cell to be treated. Known tumor suppressor proteins which have a dampening or repressive effect on the regulation of the cell cycle or promote apoptosis include, but are not limited to, p53, pRb, pVHL, APC, CD95, ST5, YPEL3, ST7, and ST14. Anti-oncogenic activity: As used herein, unless indicated otherwise or contradictory in context, the term "anti-oncogenic activity" refers to any molecule having the ability to inhibit, repress or down-regulate the gene or protein expression of oncogenes. An oncogene is a gene that has the potential to cause neoplastic diseases such as cancer. Examples of anti-oncogene molecules include tumor suppressor proteins.

By "without temporarily or permanently damaging or killing a neoplastic cell", is meant, unless indicated otherwise or contradictory in context, that a neoplastic disease, such as cancer, is treated without inducing the entry of the neoplastic cells into apoptosis as it may be assessed by the positive expression of proteins caspase 3, 6 and 7.

By "without permanently inducing a quiescent state in a neoplastic cell", is meant, unless indicated otherwise or contradictory in context, that a neoplastic disease, such as cancer, is treated by inducing a temporary quiescent state in the neoplastic cells (the cells enter the GO phase) and then differentiate into a more specialised state.

Non-mutagenic: As used herein, unless indicated otherwise or contradictory in context, the term "non- mutagenic", when used in relation to a therapy or treatment, refers to a therapy which does not involve the alteration or modification of a cell's genome. Recoding: As used herein, unless indicated otherwise or contradictory in context, the term "recoding" or "converting", when used in relation to a cell (in particular a neoplastic cell such as a cancer cell), refers to the action of providing, to a neoplastic cell to be treated, a suitable extracellular micro-environment (e.g. in the form of a pharmaceutical association or composition as defined herein) providing appropriate extracellular signals so that the cell may undergo self-recovery or -healing and be converted into a partially or fully differentiated non-neoplastic cell.

Recoding therapy: As used herein, unless indicated otherwise or contradictory in context, the term "recoding therapy" refers to a therapy that promotes and stimulates the cell's natural abilities to redirect its own fate by integrating accurate micro-environmental recoding signals.

Extracellular micro-environment: As used herein, unless indicated otherwise or contradictory in context, the term "extracellular micro-environment" refers to the environment surrounding (in functional proximity with) a specific cell which is characterized by biophysical, mechanical and biochemical properties specific for each tissue and is able to regulate cell behavior. Modification of the extracellular micro-environment of a neoplastic cell using, for instance, pharmaceutical associations or compositions as defined herein allows for the conversion or recoding of said neoplastic cell into a healthy, functional, non-neoplastic cell.

Self-recovery or self-healing: As used herein, unless indicated otherwise or contradictory in context, the term "self-recovery" or "self-healing", when used in relation to a neoplastic cell such as a cancer cell, means that the neoplastic cell operates its own internal biological changes once it has been recoded or treated using a pharmaceutical association or composition as defined herein, so that it becomes a functional, healthy, non-neoplastic cell. The cell heal itself when in contact with the pharmaceutical composition or association as defined herein and, in contrast with previously reported methods wherein the neoplastic cell is forced to die or maintained in a temporarily reduced or non-proliferative state. Physiologically functional cell: As used herein, unless indicated otherwise or contradictory in context, the term "physiologically functional cell" refers to a cell which is able to perform normally all of the cell functions associated with a particular cell type and necessary for the normal physiology of a cell. These functions include all of the intracellular molecular mechanisms but also all of the activities necessary for a normal communication between the cell and its microenvironment. One method which may be used to verify if a cell is physiologically functional is the grafting of the cell, after the introduction of fluorescent markers, in other mammalian model organisms such as mouse models. The cell is grafted in the tissue corresponding to its cell type. The cell characteristics and normal functions are monitored after a period of time with various methods such as in vivo microscopy or histological staining. The term "functional" when used in relation to a molecule, compound or substance refers to a biological molecule in a form in which it exhibits a property and/or activity by which it is characterized.

Healthy cell: As used herein, unless indicated otherwise or contradictory in context, the term "healthy cell" refers to a cell which presents a normal morphology, normal cell functions and normal cell growth which are not damaged, altered or inactivated by a neoplastic disease.

Shorter period of time: As used herein, unless indicated otherwise or contradictory in context, the term "shorter period of time", when used in relation to conversion or recoding duration, means substantially shorter to provide a substantial benefit for the treated patient in comparison with existing treatments. In certain embodiments, a shorter period of time includes at least 1 .5-fold, at least 2-fold, at least 2.5-fold, at least 3-fold, at least 3.5-fold, at least 4-fold, at least 4.5-fold, at least 5-fold, at least 6-fold, at least 7-fold, at least 8-fold, at least 9-fold or at least 10-fold reduction with respect to an existing treatment. Exogenous: As used herein, unless indicated otherwise or contradictory in context, the term "exogenous" refers to a substance coming from outside a living system such as a cell, an organ, or an individual organism. For example, in certain embodiments, exogenous factors in medicine include pathogens and therapeutics. DNA introduced into a cell via transfection or viral infection may be considered as an exogenous factor. Carcinogens are also commonly referred to as exogenous factors.

Endogenous: As used herein, unless indicated otherwise or contradictory in context, the term "endogenous" refers to substances that originate from within an organism, tissue, or cell. Intracellular: As used herein, unless indicated otherwise or contradictory in context, the term "intracellular" generally means "inside the cell". In vertebrates, such as animals, the cell membrane is the barrier between the inside of the cell and the outside of the cell (the extracellular milieu). Thus, treatments and therapies in which at least one substance, compound, pharmaceutical association, combination or composition penetrates the cell wall of a cell to be treated in order to produce/deliver its (effective) biological effect are considered as intracellular treatments and therapies.

Extracellular: As used herein, unless indicated otherwise or contradictory in context, the term "extracellular" means "outside the cell". In vertebrates, such as animals, the cell membrane is the barrier between the inside of the cell (the intracellular milieu) and the outside of the cell. Thus, treatments and therapies in which no substance, compound, pharmaceutical association, combination or composition requires penetration of the cell wall in order to produce/deliver its (effective) biological effect (e.g. by interacting with trans-membrane receptors) are considered as extracellular treatments and therapies. However, a therapy using a plurality of substances in order to provide the desired biological effect wherein one or more of these substances require the entry into the intracellular compartment to provide (or deliver) its biological effect is still considered as an extracellular therapy in the sense of the present disclosure insofar as at least one of these substances provide (or deliver) its biological effect without entering the intracellular compartment. In one example, a therapy involving the extracellular action of a GFR-binding compound and the intracellular action of an adhesion protein inhibitor (e.g. via gene silencing using si-RNAs or transcription inhibition using micro-RNAs) would still be considered as an extracellular therapy for the purpose of the present disclosure.

Cytostatic: As used herein, unless indicated otherwise or contradictory in context, the term "cytostatic" refers to inhibiting , reducing, or suppressing the growth , division, or multiplication of a cell (e.g. , a mammalian cell (e.g. , a human cell)), bacterium, virus, fungus, protozoan, parasite, prion, or a combination thereof.

Cytotoxic: As used herein, unless indicated otherwise or contradictory in context, the term "cytotoxic" refers to killing or causing injurious, toxic, or deadly effect on a cell (e.g., a mammalian cell (e.g., a human cell)), bacterium, virus, fungus, protozoan, parasite, prion, or a combination thereof.

In vitro: As used herein, unless indicated otherwise or contradictory in context, the term "in vitro" refers to events that occur in an artificial environment, e.g. , in a test tube or reaction vessel , in cell culture, in a Petri dish , etc., rather than within an organism (e.g. , animal, plant, or microbe).

In vivo: As used herein, unless indicated otherwise or contradictory in context, the term "in vivo" refers to events that occur within an organism (e.g., animal, plant, or microbe or cell or tissue thereof).

Ex vivo: As used herein, unless indicated otherwise or contradictory in context, the term "ex vivo" refers to events that occur in an external environment on tissues sourced from an organism (e.g. , animal, plant, or microbe) in an attempt to replicate natural living conditions outside such an organism. Syndecans: As used herein, unless indicated otherwise or contradictory in context, the term "syndecans" refers to single transmembrane domain proteins that are thought to act as co-receptors, especially for G protein-coupled receptors. These core proteins carry three to five heparan sulfate and chondroitin sulfate chains, which allow for interaction with a large variety of ligands including fibroblast growth factors, vascular endothelial growth factor, transforming growth factor-beta, fibronectin and antithrombin-1 . Interactions between fibronectin and some syndecans can be modulated by the extracellular matrix protein tenascin C. The syndecan protein family has four members. Syndecans 1 and 3 and syndecans 2 and 4, making up separate subfamilies, arose by gene duplication and divergent evolution from a single ancestral gene. The syndecan numbers reflect the order in which the cDNAs for each family member were cloned. All syndecans have an N-terminal signal peptide, an ectodomain, a single hydrophobic transmembrane domain, and a short C-terminal cytoplasmic domain. All syndecans are anchored to plasma membrane via a 24-25 amino acid long hydrophobic transmembrane domain . In mammalian cells, syndecans are expressed by unique genes located on different chromosomes. All members of the syndecan family have 5 exons. The difference in size of the syndecans is credited to the variable length of exon 3, which encodes a spacer domain. In humans, the amino acid length of syndecan 1 , 2, 3 and 4 is 310, 201 , 346 and 198 respectively. Glycosaminoglycan chains, a member of the heparan sulfate group, are an important component of syndecans and are responsible for a diverse set of syndecan functions. The addition of glycosaminoglycans to syndecan is controlled by a series of post- translational events.

Cyclin-dependent kinases: As used herein, unless indicated otherwise or contradictory in context, the term "Cyclin-dependent kinases" or "CDKs" refers to a family of protein involved in the regulation of the cell cycle. They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved . By definition, a CDK binds a regulatory protein called a cyclin. It is reported that, without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is considered to be an active kinase. CDKs phosphorylate their substrates on serines and threonines, so they can be said to belong to the serine-threonine kinase family. CDKs and cyclins are thus highly conserved across species and are present in all cell types including those having a neoplastic phenotype (e.g. cancer cells). Most of the known cyclin-CDK complexes regulate the progression through the cell cycle. Animal cells contain at least nine CDKs, four of which, CDK 1 , 2, 3, 4 and 6, are reported to be directly involved in cell cycle regulation: CDK1 regulated by cyclin A, cyclin B; CDK2 regulated by cyclin A, cyclin E; CDK3 regulated by cyclin C; CDK4 regulated by cyclin D1 , cyclin D2, cyclin D3; CDK5 regulated by CDK5R1 , CDK5R2; CDK6 regulated by cyclin D1 , cyclin D2, cyclin D3; CDK7 regulated by cyclin H; CDK8 regulated by cyclin C; CDK9 regulated by cyclin T1 , cyclin T2a, cyclin T2b, cyclin K. Cyclins: As used herein, unless indicated otherwise or contradictory in context, the term "cyclins" refers to a family of proteins that control the progression of cells through the cell cycle by activating cyclin- dependent kinase (CDK) enzymes. Cyclin D is one of the major cyclins produced in terms of its functional importance. It is known to interact with four CDKs: CDK2, 4, 5, and 6. In proliferating cells, cyclin D- CDK4/6 complex accumulation is of great importance for cell cycle progression. For instance, cyclin D- CDK4/6 complexes partially phosphorylates retinoblastoma tumor suppressor protein (Rb), whose inhibition can induce expression of some genes important for S phase progression. Patient/subject: As used herein, unless indicated otherwise or contradictory in context, the term "patient" or "subject", which are used interchangeably, refers to any organism to which a composition in accordance with the invention may be administered, e.g., for experimental, diagnostic, prophylactic, and/or therapeutic purposes. Typical subjects include animals (e.g., mammals such as mice, rats, rabbits, non-human primates, and humans) and/or plants. As used herein, patients/subjects include those individuals who may seek or be in need of treatment, requires treatment, is receiving treatment, will receive treatment, or a subject who is under care by a trained professional for a particular disease or condition.

Purified: As used herein, unless indicated otherwise or contradictory in context, the term "purify," "purified," "purification" means to make substantially pure or clear from unwanted components, material defilement, admixture or imperfection.

Targeted Cells: As used herein, unless indicated otherwise or contradictory in context, the term "targeted cells" refers to any one or more cells of interest. The cells may be found in vitro, in vivo, in situ or in the tissue or organ of an organism. The organism may be an animal, preferably a mammal, more preferably a human and most preferably a patient.

Molecule length: As used herein, unless indicated otherwise or contradictory in context, the term molecule or peptide "length" or "size" means the longest 2D or 3D distance which may possibly be measured within the molecule. For cyclic molecules, "length" or "size" means the longest measurable distance across the cyclic structure. Throughout the present disclosure, when a molecule size or length is given (in general using the nanometre, nm, unit), the following procedures were used to calculate them:

The so-called « 2D » procedure: a 2D chemical structure was drawn in e.g. the ChemDraw®

Software. Then, size measurement was carried out via the available ChemDraw length measurement tools. The length value given herein corresponds to the longest 2D length of the molecule using the default settings 2D bond sizes and angles of the software.

Alternatively, the so-called "3D" procedure may be followed:

(1 ) Drawing of the chemical structure of the molecule using suitable softwares (such as ChemDraw).

(2) Creating a 3D structure model of the molecule hereby drawn using SCWRL (Protein Sci. 2003;

12(9):2001 -14) or MODELLER (Current Protocols in Bioinformatics. 15:5.6:5.6.1-5.6.30), each of which is hereby incorporated by reference in its entirety.

(3) Incubating the obtained 3D structure model in a box simulation containing water for few milliseconds using AMBER (J. Computat. Chem. 2005; 26, 1668-1688), which is hereby incorporated by reference in its entirety.

(4) Measuring the size of the molecule hereby obtained using softwares such as Pymol® using available Pymol length measurement tools (DeLano Scientific LLC, http://www.pymol.org).

Root Mean Square Deviation: As used herein, unless indicated otherwise or contradictory in context, the term "Root Mean Square Deviation" or "RMSD" is well known in the art and means the square root of the arithmetic mean of the square of the distances between certain matched atoms. One can represent a molecular conformation as a vector whose components are the Cartesian coordinates of the molecule's atoms. Therefore, a conformation for a molecule with N atoms can be represented as a 3N-dimensional vector of real numbers. To calculate the RMSD of a pair of peptides or peptidomimetics (e.g. x and y), each one of them must be represented as a 3N-length (assuming N atoms) vector of coordinates. The RMSD is therefore the square root of the arithmetic mean of the square of the distances between corresponding atoms of x and y. It is a measure of the average atomic displacement between the conformations of the two structures:

In other words, the RMSD is the measure of the average distance between the atoms (usually the backbone atoms) of superimposed polypeptides or peptidomimetics. In the study of globular protein conformations, one customarily measures the similarity in three-dimensional structure by the RMSD of the Ca atomic coordinates after optimal rigid body superposition.

The RMSD value of a given peptide or peptidomimetic with respect to a specifically selected reference structure (hereinafter may also be referred to as "PEPREF") may be calculated using various methods all well know by the skilled person. However, for the purpose of the present disclosure and for the avoidance of doubts, the RMSD of a given peptide or peptidomimetic as used in the present disclosure is obtained precisely using the following procedure:

STEP 1 : Creating a 3-dimensional model of (i.e. obtaining 3D structure coordinates for) a peptide or peptidomimetic for which the RMSD is to be calculated, by:

STEP 1.1 : Obtaining a set of polypeptide 3D structure coordinates based on the alignment with the sequence of a peptide or peptidomometic for which the RMSD value is to be calculated, using the BLAST algorithm according to the following procedure:

1. Open the following link to access the "Standard Protein Blast" tool:

http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastp&P AGE_TYPE=BlastSearch&LINK_LO C=blasthome

2. Enter the amino acid sequence of the peptide or peptidomimetic of interest in the "Enter Query Sequence" section. The alignment is performed one sequence after the other (this is not a multiple alignment tool).

3. In the section "Choose Search Set", choose the following database: Protein Data Bank Proteins (pdb).

4. In the section "Choose Search Set", do not exclude « Models (XM/XP) » and do not Exclude « Uncultured /environmental sample sequences ».

6. Leave other fields as shown on the screenshot in Figure 20.

7. Run BLAST.

8. The results obtained from the query are presented in the form of several pdb files.

9. From this output results, the first ten (10) PDB files corresponding to the best sequence alignments are retained. This set of 10 PDB files or structures will be used in the next step (Step 2: structural alignments with STAMP).

10. Finally, clean up the 10 structures contained in the 10 PDB files by removing all e.g. additional small molecules, receptors or portions thereof, dimers or portions thereof, so as to retain only the polypeptide chain of interest.

The set of pdf files contains the polypeptide 3D structure coordinates of the 10 structures having the highest sequence homology with the peptide or peptidomometic for which the RMSD value is to be calculated. STEP 1.2: Performing the structural alignment of the set of 3D structure coordinates obtained in STEP 1.1 , thereby obtaining a set of aligned polypeptide 3D structure coordinates, by using STAMP (Structural Alignment of Multiple Proteins Version 4.2) according to the following procedure:

1. Open the following link to access the "STAMP superposition" tool: http://www.russelllab.org/cgi- bin/pdc/stamp.pl

2. In the section entitled "Structure A", input the PDB file corresponding to the first structure from the set of ten 3D structure coordinates obtained in STEP 1.1 , which corresponds to the best sequence alignment with BLAST.

3. In the section entitled "Structure B", input the PDB file corresponding to the second structure from the set of ten 3D structure coordinates obtained in STEP 1.1 , which corresponds to the second best sequence alignment with BLAST.

4. Run STAMP.

5. Repeat steps 2 to 4 with the other eight pdb files from the set of ten 3D structure coordinates identified in STEP 1.1 by successively entering the PDB files in the field "Structure B".

6. As a result, the structural alignment of the 10 structures contained in the set of PDB files obtained in STEP 1.1 is obtained in the form of 9 disctinct PDB files each containing a pair of aligned polypeptide 3D structure (structure 1 with structure 2, structure 1 with structure 3, structure 1 with structure 4, ... , structure 1 with structure 10).

7. From these 9 "pair" PDB files, 10 PDB files each containing one of structures 1 to 10 are created. 8. 10 PDB files containing the aligned 3D structure coordinates are thus obtained from STEP 1.2. for use in the next step. STEP 1.3: Modelling the sequence of peptide or peptidomometic for which the RMSD value is to be calculated against the set of aligned polypeptide 3D structure coordinates obtained in STEP 1.2, thereby obtaining a set of 3D structure coordinates for the peptide or peptidomometic for which the RMSD value is to be calculated, using SCWRL (reference: "SCWRL and MollDE: computer programs for side-chain conformation prediction and homology modeling", Nature Protocols VOL.3 NO.12 2008, Qiang Wang et al.; which is hereby incorporated by reference in its entirety) according to the following procedure:

5. Repeat steps 1 to 3 using the 9 remaining PDB files obtained in STEP 1.2.

6. 10 PDB files are obtained from STEP 1.3 for use in the following STEP 1 .4.

STEP 1.4: Minimizing the free energy (AG) of the set of 3D structure coordinates for the peptide or peptidomometic for which the RMSD value is to be calculated obtained in STEP 1.3 using GROMACS (Reference: Hess B, Kutzner C, Van Der Spoel D, Lindahl E (2008). "GROMACS 4: Algorithms for Highly Efficient, Load-Balanced, and Scalable Molecular Simulation". J Chem Theory Comput 4 (2): 435; which is hereby incorporated by reference in its entirety) according to the following procedure: 1. Create a Gromacs topology (gmx) file from the first PDB file of the modeled peptide or peptidomometic for which the RMSD value is to be calculated obtained in STEP 1 .3, by using the command « pdb2gmx -f NOMDUFICHIERPDB.pdb -water spc». "NOMDUFICHIERPDB" is the name of the input PDB file.

2. Create a box around the imported modeled peptide or peptidomometic by using the command « editconf -f conf.gro -bt cubic d 0.7 o box.gro».

3. Add solvent (water) molecules into the box by using the command « genbox -cp box.gro -cs spc216.gro -p topol.top - o solvated.gro».

4. Prepare the input for the molecular dynamics (MD) run with the command « vim em.mdp ». Default run is set to 1000 nsteps.

8. As a result, a first XMG file is obtained. To view the XMG file run the command « xmgrace em.xvg ». 9. Repeat steps 1 to 8 with the 9 remaining structures obtained in STEP 1 .3. 10 XMG files are thus obtained.

10. The structure of lowest energy is obtained from each XMG file in the form of a PDB file. 10 PDB files each containing one structure of lowest energy are thus obtained from STEP 1 .4 for use in the next step.

STEP 2: Calculating the RMSD of the peptide or peptidomimetic for which the RMSD value is to be calculated by comparing the 3D structure coordinates of the peptide or peptidomimetic obtained in STEP 1.4 with the 3D structure coordinates of PEPREF to obtain the lowest possible RMSD value using FATCAT (Flexible structure AlignmenT by Chaining Aligned fragment pairs allowing Twists) according to the following procedure: 1. Open the following link to access the "FATCAT" software: http://fatcat.burnham.org

2. Open the "pairwise alignment" tool.

3. Import the PDB file containing the structure coordinates of PEPREF in the "Get the 1 st structure" section.

4. Import the first PDB file of the peptide or peptidomimetic for which the RMSD value is to be calculated with minimized energy obtained in STEP 1.4.

5. Run FATCAT.

7. Repeat steps 1 to 5 with the 9 remaining structures (PDB files) obtained from STEP 1 .4.

8. The peptide or peptidomimetic structure with the lowest RMSD (out of the ten RMSD values successively obtained) is the value taken into account in the present application.

3D structure coordinates of PEPREF: As used herein, unless indicated otherwise or contradictory context, the 3D structure coordinates of PEPREF are as follows:

Structure coordinates: As used herein, unless indicated otherwise or contradictory in context, the "structure coordinates" refers to Cartesian coordinates derived from mathematical equations related to the patterns obtained on diffraction of a monochromatic beam of X-rays by the atoms (scattering centers) of a protein, protein complex or peptide in crystal form. The diffraction data are used to calculate an electron density map of the repeating unit of the crystal. The electron density maps are then used to establish the positions of the individual atoms of the molecule or molecular complex.

STAMP: STAMP (Structural Alignment of Multiple Proteins) is a tool for aligning protein sequences based on a three-dimensional structure. Its algorithm minimizes the Ca distance between aligned residues of each molecule by applying globally optimal rigid-body rotations and translations. This program provides some information on the equivalence of the residues between the selected models. SCWRL: This program predicts and optimizes the protein side-chain conformations. It is using the backbone of a support protein and a backbone-dependent rotamer library. The possible conformations are explored by minimizing the steric hindrance between the side-chains and between the side-chains and the backbone. GROMACS: GROMACS is a molecular dynamics package. The "gmx rms" tool included in GROMACS compares two structures by computing the root mean square deviation (R SD).

In one aspect, the present disclosure provides for non-mutagenic extracellular therapies having the ability to direct cell fate. It is thus possible to convert or recode a neoplastic cell by modifying its surrounding extracellular micro-environment, in-vitro, ex-vivo or in-vivo, so that the cell operates self-recovery or self- healing and a subject possessing such a neoplastic cell may be protected from a neoplastic disease.

In one example, a neoplastic cell may operate self-recovery or self-healing e.g. by inducing a quiescence state so that the neoplastic cell may remain inactive or dormant for seconds, minutes, hours, days, weeks, months or years, in particular, will never resume neoplasia; and/or by preventing, reducing or suppressing cell division and/or cell proliferation, preferably uncontrolled cell division and/or cell proliferation of said neoplastic cell; and/or by regulating or promoting anti-mitogen activity and/or tumour suppressor pathways and/or anti-oncogenic activity in said neoplastic cell; and/or by inducing cytostaticity and not cytotoxicity in the neoplastic cell; and/or by inducing differentiation; and/or by regulating and/or modulating the adhesion or interactions between the cell and its micro-environment (i.e. the surrounding ECM) so as activate, reactivate or restore cell adhesion checkpoints in said neoplastic cell.

In one aspect, the present disclosure provides a pharmaceutical association or combination having the ability to convert or recode, extracellularly, a neoplastic cell, in-vitro, ex-vivo or in-vivo, so that it may be used in the treatment, prevention and/or diagnostic of a neoplastic disease, said association comprising at least one growth factor receptor-binding compound which activates at least one growth factor receptor of a cell (in particular a neoplastic cell) and at least one adhesion protein inhibitor or antagonist which inhibits or antagonises at least one transmembrane cell adhesion protein of said cell. In certain embodiments, said pharmaceutical association or combination reduces, down-regulates, inhibits or suppresses (i) the gene and/or protein expression of at least one cyclin-D in the cell (in particular a neoplastic cell) and/or (ii) the formation of at least one complex formed between said at least one cyclin-D and at least one of cyclin dependent-kinase (CDK) 4 or 6 in the cell (in particular a neoplastic cell).

II. Growth factor receptor-binding compounds

In this method, a GFR-binding compound is fluorescently labelled using technics well established in the art. Binding of the resulting labelled compound to a growth factor receptor results in a fluctuation of fluorescence anisotropy which is used to construct an affinity binding curve from which the GFR-binding compound binding affinity value is derived. Using this technique, binding affinity values are given in the form of dissociation constants Kd. In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 1 (one) picomolar (p ). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 1 (one) nanomolar (nM). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 10 (ten) nanomolar (nM). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 100 (one hundred) nanomolar (nM). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 1 (one) micromolar (μΜ). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 10 (ten) micromolar (μΜ). In certain embodiments, GFR-binding compounds of the present disclosure have Kd values as measured by fluorescence anisotropy of more than 100 (one hundred) micromolar (μΜ).

There are many ways to test and measure the ability of a given substance to activate a given receptor, but for the purpose of the present disclosure, and for the avoidance of any doubts, a given GFR-binding compound activates a growth factor receptor if it induces growth factor receptor phosphorylation as measured by the western blot method. There are many distinct phosphorylation sites on growth factor receptors and they may widely vary according to the type of growth factor receptor as reported in the published scientific article from Mark A.

In one example, a neoplastic cell of a soft tissue such as a muscle, vascular, skin or kidney tissue (i.e. a neoplastic cell from the muscle, vascular, skin or kidney cell lineage, respectively) has been , may be or will be the cause of the development of a neoplastic muscle, vascular, skin or kidney disease (e.g. Rhabdomyosarcoma, Hemangiosarcoma, basal cell carcinoma or Squamous cell carcinoma, respectively). Inducing the conversion of any of these neoplastic cells into a physiologically functional and/or healthy cell (any physiologically functional and/or healthy cell) of the muscle, vascular, skin or kidney cell lineage, respectively, may protect a subject carrying any of these cells from the diseases mentioned above. In some cases, it may be preferable and/or satisfying and/or more practical to induce the conversion of, e.g. a neoplastic muscle, vascular, skin or kidney cell into a functional and/or healthy cell of a different cell lineage i.e. not a cell from a muscle, vascular, skin or kidney lineage, such as, for example, in certain embodiments, a cell from a bone cell lineage so that a medical practitioner such as a surgeon , may be able to surgically remove the newly converted bone cells more conveniently. The surgery may be carried out purely for aesthetic reasons and/or because of a discomfort and/or to avoid the possibility of e.g. infections, complications, etc.

For example, in certain embodiments, a neoplastic cell of an adipose tissue (i.e. a neoplastic cell from the adipocyte lineage) has been, may be or will be the cause of the development of a neoplastic adipose tissue disease (e.g. adipose tissue cancer or lipoma). Several treatment routes may be envisaged to induce the conversion of this neoplastic adipocyte into a physiologically functional and/or healthy cell and thus protect a subject/patient carrying this cell from a lipoma. In some cases, it may be preferable and/or satisfying and/or more practical to induce the conversion of the neoplastic adipocyte into a functional and/or healthy cell of a bone cell lineage. Once the treatment has been completed i.e. after the conversion of the neoplastic adipocyte into a non-neoplastic bone cell (e.g . an osteocyte) has taken place, surgical removal of the newly converted bone cells may be performed for e.g. aesthetic reasons and/or because of a discomfort and/or to avoid the possibility of e.g. infections, complications, etc. In other cases, it may be preferable and/or satisfying and/or more practical to induce the conversion of the neoplastic adipocyte into a functional and/or healthy cell of a muscle cell lineage. Because the conversion of the neoplastic adipocyte into a non-neoplastic muscle cell (e.g. a myocyte) does not yield hard tissues such as osteocytes, the patient would generally not feel any substantial discomfort and therefore, the surgical removal of the newly converted muscle cells may be avoided, although it may still be performed if the patient were to feel even the slight discomfort. The necessity of performing surgery following the presently defined receding treatment would generally be left to the appreciation of the patient upon supervision of a medical practitioner.

The present disclosure thus provides methods to convert or recode a neoplastic cell of a specific tissue/cell type (e.g. bone, cartilage, neuron, prostate, ovary, muscle, skin, vascular, ligament, tendon, eye retina, kidney, head, neck, blood, gastrointestinal, lung and adipose tissues) into a non-neoplastic cell of any tissue/cell type (e.g. bone, cartilage, neuron, prostate, ovary, muscle, skin, vascular, ligament, tendon, eye retina and kidney).

III. Adhesion protein inhibitor

The present invention achieves its intended therapeutic action(s) i.e. the treatment of a neoplastic disease via extracellular, non-mutagenic, receding or conversion of neoplastic cells, by providing an association (or combination) of at least two bioactive substances, namely, at least one GFR-binding compound as described herein and at least one adhesion protein inhibitor or adhesion molecule inhibitor. In one aspect, the present disclosure thus provides at least one adhesion protein inhibitor, as part of a pharmaceutical association or combination as defined herein, as an active principle for use in methods and uses described herein.

In one example, said GFR-binding compound and said adhesion protein inhibitor may be operably covalently or non-covalently associated, combined, linked or connected as defined herein.

Various methods known in the art may be used to assess the deactivation or inhibitory activity or potency of a given adhesion protein inhibitor on a given adhesion protein such an integrin or a syndecan. However, for the avoidance of doubts and for the purpose of the present disclosure, the assessment of the inhibition or deactivation of adhesion protein(s) by a given adhesion protein inhibitor as defined herein (alone or within a pharmaceutical association, combination or composition as defined herein) is performed using fluorescence resonance energy transfer (FRET). This method is able to measure with high precision the degree of protein conformational changes that are associated with the action of a specific adhesion protein inhibitor on a given adhesion protein and thus quantify the inhibitory effect of the adhesion protein inhibitor. FRET is a well-known and recognised analytical method, but for the avoidance of doubts and for the purpose of the present disclosure, the experimental procedures, parameters and setup are those described in Chigaev, A., Buranda, T., Dwyer, D. C, Prossnitz, E. R. and Sklar, L. A. (2003), "FRET detection of cellular a4-integrin conformational activation", Biophys. , J . 85, 3951 -3962, which is hereby incorporated by reference in its entirety.

As used herein, unless stated otherwise or contradictory in context, the terms "inhibition", "down- regulation", "deactivation" or "inactivation", when used in the context of cell adhesion, refers to a diminution or reduction in activity, function, gene expression and/or protein expression of a molecule, protein or gene, observed when a pharmaceutical association, combination or composition of the present disclosure is provided or administered to a cell or to a subject carrying this cell , using one of the methods defined herein, in comparison with the activity, function, gene expression and/or protein expression of a molecule, protein or gene in a neoplastic cell in the absence of such provision or administration, of more than 10%, 1 1 %, 12%, 13%, 14%, 15%, 1 6%, 17%, 18%, 19%, 20%, 21 %, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31 %, 32% , 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41 %, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50% , 51 %, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61 %, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71 %, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81 %, 82%, 83%, 84%, 85%, 86% , 87%, 88%, 89%, 90%, 91 %, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99%, in particular of more than 20%. In one particular example, said inhibition is more than 30%. In one particular example, said inhibition is more than 40%. In one particular example, said inhibition is more than 50%. In one particular example, said inhibition is more than 60%. In one particular example, said inhibition is more than 70%. In one particular example, said inhibition is more than 80%.

In certain embodiments, the inhibition of cell adhesion comprises (or is exclusively constituted of, or exclusively consists of) the inhibition, deactivation or down-regulation of the gene or protein expression of one or more integrins, syndecans, selectins, dystroglycans or any combinations thereof. In one aspect, the present disclosure also provides a use of an adhesion protein inhibitor as defined herein in the manufacture of a medicament comprising a GFR-binding compound as defined herein, for use in the diagnostic, prevention and/or treatment of a neoplastic disease.

One particular biological checkpoint that the present invention is able to re-establish, repair or restore is the cell adhesion checkpoint. The cell adhesion checkpoint is known to be in charge of monitoring the cells attachments to the extracellular matrix (ECM). In normal conditions, when a cell does not detect a "correct" attachment it should halt further advance through the cell cycle and enter the GO phase.

Cell adhesion is the binding of a cell to a surface or substrate, such as the extracellular matrix (ECM). Adhesion occurs from the action (or engagement) of proteins, called cell adhesion proteins or molecules. Examples of such cell adhesion proteins are cell transmembrane adhesion proteins, such as the integrins, syndecans, selectins and dystroglycans. The most important among these proteins are the integrins, which assemble as alpha-beta heterodimers. 111.1. Integrins

The integrins belong to a superfamily of cell adhesion receptors that bind to extracellular matrix ligands, cell-surface ligands, and soluble ligands. They are transmembrane αβ heterodimers and at least 18 a and 8 β subunits are known in humans, generating 24 heterodimers such as α1 β1 , α2β1 , α3β1 , α4β1 , α5β1 , α6β1 , α7β1 , αΙ_β2, αΜβ2, αΙ^β3, ανβ1 , ανβ3, ανβ5, ανβ6, ανβδ, and α6β4. Members of this family have been found in mammals, chicken and zebrafish, as well as lower eukaryotes. The a and β subunits have distinct domain structures, with extracellular domains from each subunit contributing to the ligand- binding site of the heterodimer. The sequence arginine-glycine-aspartic acid (RGD) was identified as a general integrin-binding motif, but individual integrins are also specific for particular protein ligands. In addition to physically linking the cell to the extracellular matrix, the binding of the extracellular integrin domains to specific components of the ECM activates the integrins and allows binding of different signalling molecules to their intracellular domain. This activates various signalling pathways that mediate signals to the adhesion checkpoint.

The activation of an integrin is associated with structural conformational changes of the protein. Integrins are known to adopt three major conformational states: « inactive » (low affinity), « primed » or « active » (high affinity), and ligand occupied (which may be activated or not depending on the nature of the ligand). The active form of the protein is considered as having an « extended » conformation while the inactive form is considered as « bent » with bending of the ligand-binding headpiece of its extracellular domain. Upon activation the integrin proceeds with an unbending of this domain to acquire the extended conformation, which is able to bind the ECM components. This process initiates further conformational changes, which activate, through the intracellular domain several signaling pathway cascades.

In the present disclosure, the pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein is thus suitable for treating a neoplastic cell or a neoplastic disease (i) by activating one or more growth factor receptors and (ii) by, simultaneously or non-simultaneously, modulating or regulating the adhesion of that cell to its ECM microenvironment by (partially or completely) deactivating or inhibiting at least one integrin expressed on the cell membrane of said neoplastic cell. In certain embodiments, and without wishing to be bound to any specific theory, the deactivation or inhibition of an integrin may be the result of, for example, integrin's inactivation, integrin's dimerisation inhibition, and/or integrin's gene expression inhibition. In certain embodiments, the adhesion protein inhibitor as defined herein comprises (or is) an integrin deactivator or inhibitor which binds to/interacts with at least one integrin and/or to at least one integrin dimer. In one example, said integrin deactivator or inhibitor is a receptor competitive antagonist. In one example, said integrin deactivator or inhibitor is a receptor non-competitive antagonist. In one example, said integrin deactivator or inhibitor is a receptor uncompetitive antagonist. In one example, said integrin deactivator or inhibitor is a receptor silent antagonist. In one example, said integrin deactivator or inhibitor is a receptor partial agonist. In one example, said integrin deactivator or inhibitor is a receptor inverse agonist.

In one aspect, the present disclosure thus provides a pharmaceutical association or combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein comprising at least one GFR-binding compound as defined herein and at least one inhibitor of integrin engagement with the ECM. In certain embodiments, said at least one inhibitor of integrin engagement with the ECM is an anti-integrin antibody. One aspect of the present disclosure thus also provides a pharmaceutical association or combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein comprising at least one GFR-binding compound as defined herein and at least one integrin antibody.

Conveniently, the integrin antibody or antibodies is/are the antibody or antibodies which is/are predominantly expressed on the surface of a given neoplastic cell and will thus vary according to the type and nature of the neoplastic cell to be treated using the recoding therapy as defined herein.

In certain embodiments, said at least one inhibitor of integrin engagement with the ECM is a Arginylglycylaspartic acid (RGD) peptide. One aspect of the present disclosure thus also provides a pharmaceutical association or combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein comprising at least one GFR-binding compound as defined herein and at least one RGD peptide.

In certain embodiments, the adhesion protein inhibitor as defined herein comprises (or is) an integrin deactivator or inhibitor which inhibits or down-regulates the gene or protein expression of at least one integrin by e.g. alteration of the chromatin structure (e.g. through histone modifications), regulation of gene transcription (e.g. by acting on specificity factors, repressors, general transcription factors, activators, enhancers and/or silencers), post-transcriptional regulation, and/or regulation of translation.

In one aspect, the present disclosure thus provides a pharmaceutical association or combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein comprising at least one GFR-binding compound as defined herein and at least one small-interfering RNA (si-RNA) which interferes with or inhibit the gene or protein expression of at least one integrin.

Integrins expressed on the cell membrane of neoplastic cells may be identified using various methods. However, for the avoidance of doubts and for the purpose of the present disclosure, identification of such integrin(s) is performed using e.g. RT-PCR or western blot. Because, the type of integrins expressed on the cell membrane of a given cell (e.g. a neoplastic cell) may differ from the integrins expressed in the cell membrane of another (neoplastic) cell, prior identification of the integrins expressed on the cell membrane of a cell to be treated using a method such as RT-PCR, allows for a more tailored, personalised and/or efficient treatment to be provided.

In certain embodiments, the modulation or regulation of a neoplastic cell adhesion thus comprises (or is exclusively constituted of, or exclusively consists of) the inhibition, deactivation or down-regulation of the gene or protein expression of one or more identified integrins or dimers of integrins expressed by the neoplastic cell to be treated using, for example, conventional techniques known in the art such as gene silencing using small-interfering RNAs, microRNAs or shRNAs, integrin extracellular antibodies and/or integrin antagonists. The identification of said specific one or more integrins or dimers of integrins may be carried for each specific neoplastic cell using conventional methods in the art such as the one described herein.

Various methods known in the art may be used to qualify and/or quantify the degree of deactivation or inhibitory activity of a given adhesion protein inhibitor on the gene expression of integrins. However, for the avoidance of doubts and for the purpose of the present disclosure, assessment of integrins gene expression of a given cell by an adhesion protein inhibitor as defined herein is performed using RT-PCR as already defined herein.

Various methods known in the art may be used to qualify and/or quantify the degree of deactivation or inhibitory activity of a given adhesion protein inhibitor on the protein expression of integrins. However, for the avoidance of doubts and for the purpose of the present disclosure, assessment of integrins protein expression of a given cell by an adhesion protein inhibitor as defined herein is performed using the western blot method as already defined herein.

Various methods known in the art may be used to qualify and/or quantify the degree of activation or inactivation/inhibition state of integrins. However, for the avoidance of doubts and for the purpose of the present disclosure, assessment of the integrins activation or inactivation state of a given cell by an adhesion protein inhibitor as defined herein is performed using FRET as already defined herein.

Also provided is a method of treating a neoplastic cell or a neoplastic disease by (partially or completely) deactivating or inhibiting at least one integrin or dimer of integrins expressed on the cell membrane of said neoplastic cell, comprising administering to a subject in need thereof an effective amount of a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein.

Also provided is a method of treating a neoplastic cell or a neoplastic disease comprising identifying at least one integrin or dimer of integrin expressed on the membrane of said neoplastic cell, and (partially or completely) deactivating or inhibiting said at least one integrin or dimer of integrin by administering to a subject in need thereof an effective amount of a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein. Ill .2. Syndecans

As used herein, unless indicated otherwise or contradictory in context, the term "syndecans" refers to single transmembrane domain proteins that are thought to act as co-receptors, especially for G protein- coupled receptors. These core proteins carry three to five heparan sulfate and chondroitin sulfate chains, which allow for interaction with a large variety of ligands including fibroblast growth factors, vascular endothelial growth factor, transforming growth factor-beta, fibronectin and antithrombin-1. Interactions between fibronectin and some syndecans can be modulated by the extracellular matrix protein tenascin C. The syndecan protein family has four members. Syndecans 1 and 3 and syndecans 2 and 4, making up separate subfamilies, arose by gene duplication and divergent evolution from a single ancestral gene. The syndecan numbers reflect the order in which the cDNAs for each family member were cloned. All syndecans have an N-terminal signal peptide, an ectodomain, a single hydrophobic transmembrane domain, and a short C-terminal cytoplasmic domain. All syndecans are anchored to plasma membrane via a 24-25 amino acid long hydrophobic transmembrane domain. In mammalian cells, syndecans are expressed by unique genes located on different chromosomes. All members of the syndecan family have 5 exons. The difference in size of the syndecans is credited to the variable length of exon 3, which encodes a spacer domain. In humans, the amino acid length of syndecan 1 , 2, 3 and 4 is 310, 201 , 346 and 198 respectively. Glycosaminoglycan chains, a member of the heparan sulfate group, are an important component of syndecans and are responsible for a diverse set of syndecan functions. The addition of glycosaminoglycans to syndecan is controlled by a series of post- translational events.

In the present disclosure, the pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein is thus suitable for treating a neoplastic cell or a neoplastic disease (i) by activating one or more growth factor receptors and (ii) by, simultaneously or non-simultaneously, modulating or regulating the adhesion of that cell with its ECM microenvironment by (partially or completely) deactivating or inhibiting at least one syndecan expressed on the cell membrane of said neoplastic cell. In certain embodiments, and without wishing to be bound to any specific theory, the deactivation or inhibition of a syndecan may be the result of, for example, syndecan's inactivation, syndecan's dimerisation inhibition, and/or syndecan's gene expression inhibition.

III.3. Selectins

The selectins are a family of cell adhesion molecules. All selectins are single-chain transmembrane glycoproteins. Selectins bind to sugar moieties and so are considered to be a type of lectin, cell adhesion proteins that bind sugar polymers. All three known members of the selectin family (L-, E-, and P- selectin) share a similar cassette structure: an N-terminal, calcium-dependent lectin domain, an epidermal growth factor (EGF)-like domain, a variable number of consensus repeat units (2, 6, and 9 for L-, E-, and P- selectin, respectively), a transmembrane domain (TM) and an intracellular cytoplasmic tail (cyto). Selectins have hinge domains, allowing them to undergo rapid conformational changes in the nanosecond range between Open' and 'closed' conformations. Shear stress on the selectin molecule causes it to favor the Open' conformation.

In the present disclosure, the pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein is thus suitable for treating a neoplastic cell or a neoplastic disease (i) by activating one or more growth factor receptors and (ii) by, simultaneously or non-simultaneously, modulating or regulating the adhesion of that cell to its ECM microenvironment by (partially or completely) deactivating or inhibiting at least one selectin expressed on the cell membrane of said neoplastic cell.

Ill .4. Dystroglycans

Dystroglycan is a protein that in humans is encoded by the DAG1 gene. Dystroglycan is one of the dystrophin-associated glycoproteins, which is encoded by a 5.5 kb transcript in Homo sapiens on chromosome 3. There are two exons that are separated by a large intron. The spliced exons code for a protein product that is finally cleaved into two non-covalently associated subunits, [alpha] (N-terminal) and [beta] (C-terminal). The dystroglycan complex works as a transmembrane linkage between the extracellular matrix and the cytoskeleton. [alpha]-dystroglycan is extracellular and binds to merosin [alpha]-2 laminin in the basement membrane, while [beta]-dystroglycan is a transmembrane protein and binds to dystrophin, which is a large rod-like cytoskeletal protein. Dystrophin binds to intracellular actin fibers.

In certain aspects, said pharmaceutical association or composition substantially down-regulates, reduces, inhibits or suppresses the gene and/or protein expression of at least one of cyclin-D 1 , cyclin-D2 or cyclin- D3. Because cyclins D1 , D2 and D3 regulate the activity of Cyclin-dependent kinases (CDKs) 4 and 6 by forming cyclin-CDK protein complexes including Cyclin D1 -CDK4 complex, Cyclin D1 -CDK6 complex, Cyclin D2-CDK4 complex, Cyclin D2-CDK6 complex, Cyclin D3-CDK4 complex and Cyclin D3-CDK6 complex, said pharmaceutical association or composition was also observed to substantially reduce, inhibit, suppress or destabilise the formation of any one of such complexes.

There are many ways to test, measure and represent the inhibitory effect of a given substance on the gene or protein expression of cyclins D, but for the purpose of the present disclosure, and for the avoidance of any doubts, the inhibition values of a given pharmaceutical association or composition as defined herein is a measure of the gene expression of cyclins D as provided by RT-PCR. It is to be understood that the values of the gene expression of cyclins D disclosed herein correspond to the total gene expression of all cyclins D present in the tested cell i.e. D1 , D2 and D3 as known at the date of the present disclosure.

As already stated above, pharmaceutical associations or compositions suitable for implementing embodiments of the present invention reduce the gene expression of cyclins D by at least 20% during at least one part of the G 1 phase of the cell cycle as compared to the wild-type expression. The absolute and relative duration of each cell cycle phase (in other words, the cell cycle duration profile) usually varies (some phases such as the Gap phases may "shrink") amongst healthy cells of different types (e.g. bone cells, skin cells, etc .. ) and between healthy cells and neoplastic cells of the same type (e.g. healthy bone cells and neoplastic bone cells). Typical average cell cycle duration is commonly accepted to be about 24 hours. Typically accepted phase durations for a healthy cell are 1 1 to 14 hours for the G1 phase, 5 to 12 hours for the S phase, 3 to 12 hours for the G2 phase and about 1 hour for the M phase. In neoplastic cells, such as in cancer cells, it is commonly admitted that, although the duration of the S and M phases may generally be conserved, the length of the G1 and G2 phases is generally shortened in order to increase cell division. Cell cycle phase's duration may thus vary significantly from one cell type to another. Consequently, conventionally and for the purpose of facilitating the comparative representation of the inhibition of the gene expression of cyclins D for different cell types, the gene expression is represented as a function of the cell cycle progression (starting from G1 and finishing with M) and not as a direct function of time.

One may thus inject or administer, to a mammal subject, at least one GFR-binding- peptide-encoding polynucleotide or at least one adhesion protein inhibitor- or antagonist-encoding polynucleotide (such as a messenger RNA), wherein said polynucleotide would enable the intracellular production of the encoded GFR-binding peptide or adhesion protein inhibitor or antagonist, which may, once released outside the host cell, exert its extracellular action on the host cell and/or on neighbouring cells and/or distant cells in combination with its complementary extracellular biologically active partner (i.e. a GFR-binding-peptide or an adhesion protein inhibitor or antagonist, as the case may be). In other words, GFR-binding peptides or adhesion protein inhibitors or antagonists may be produced ex-vivo (e.g. using a peptide synthesizer or recombinantly produced) or in-vivo (e.g. via cell expression of encoding polynucleotides), and in all cases have an extracellular combined biological action of (i) activation of growth factor receptors and (ii) inhibition, deactivation, or disengagement action of at least one adhesion protein, to induce cell conversion or recoding of a neoplastic cell into a non-neoplastic cell.

Alternatively, one may also inject or administer, to a mammal subject, at least one GFR-binding-peptide- encoding polynucleotide and at least one adhesion protein inhibitor- or antagonist-encoding polynucleotide (such as a messenger RNA), wherein said polynucleotides would enable the intracellular production of both, the encoded GFR-binding peptide and the adhesion protein inhibitor or antagonist, which may, once released outside the host cell, exert their combined extracellular action on the host cell and/or on neighbouring cells and/or distant cells. In other words, GFR-binding peptides and adhesion protein inhibitors or antagonists may all be produced ex-vivo (e.g. using a peptide synthesizer or recombinantly produced) or in-vivo (e.g. via cell expression of encoding polynucleotides), and in all cases have an extracellular combined biological action of (i) activation of growth factor receptors and (ii) inhibition, deactivation, or disengagement action of at least one adhesion protein, to induce cell conversion or recoding of a neoplastic cell into a non-neoplastic cell.

In one aspect, the present disclosure also provides a medical composition comprising one or more polynucleotide(s), one or more vector(s), or one or more transfected cell(s), all as defined in the present disclosure, and a medically acceptable excipient or carrier. Expression: As used herein, "expression" of a nucleic acid sequence refers to one or more of the following events: (1 ) production of an RNA template from a DNA sequence (e.g., by transcription); (2) processing of an RNA transcript (e.g., by splicing, editing, 5' cap formation, and/or 3' end processing); (3) translation of an RNA into a polypeptide or protein; and (4) post-translational modification of a polypeptide or protein. mRNA: As used herein, the term "mRNA" refers to messenger RNA. Traditionally, the basic components of an mRNA molecule include at least a coding region, a 5'UTR, a 3'UTR, a 5'cap and a poly-A tail. Whereas the 5'UTR, 3'UTR, 5'cap and the poly-A tail are usually required to improve e.g. stability, translation and/or recognition by the ribosome, it is the coding region which comprises the sequence encoding the protein(s), polypeptide(s), or peptide(s) of (therapeutic) interest. Therefore, when the mRNA molecule as disclosed herein is conventionally described with reference to its coding region, any mRNA molecule also comprising at least one of a 5'UTR, a 3'UTR, a 5'cap or a poly-A tail forms an integral part of the present disclosure. Coding region: As used herein, the term "coding region" or "coding sequence" refers to a portion of a polynucleotide that codes for a peptide or peptides of interest.

Primary RNA construct or transcript: As used herein, unless indicated otherwise or contradictory in context, the term "Primary RNA construct" or "Primary RNA transcript" refers to any precursor RNA molecule from a mature and functional (i.e. translatable) RNA molecule may be obtained. For instance, a precursor messenger RNA (pre-mRNA) is a type of primary transcript that becomes a messenger RNA (mRNA) after processing. Newly synthesized primary transcripts are modified in several ways to yield their mature form before they can be translated into a protein of interest. Such modifications include, but are not limited to, excision of introns, splicing of exons, addition of 5'cap and poly-A tail. Therefore, when reference is made to an RNA molecule, it shall be understood that it aims to cover all RNA molecules including, but not limited to, primary RNA transcripts or constructs at any stage of the modification process leading to a mature and functional RNA molecule e.g. with or without introns, exons, 5'cap, poly- A tail and/or any other conventional modifications, insofar as the RNA molecule contains a coding region or a precursor thereof allowing for a peptide of interest encoded by said coding region or precursor thereof to be expressed. 5" Capping: As used herein, unless indicated otherwise or contradictory in context, the term "5' Capping" ou "5' Cap" refers to a 5' cap structure of an mRNA that is involved in nuclear export, increasing mRNA stability and binds the mRNA Cap Binding Protein (CBP), which is responsible for mRNA stability in the cell and translation competency through the association of CBP with poly(A) binding protein to form the mature cyclic mRNA species. The cap further assists the removal of 5' proximal introns removal during mRNA splicing. Endogenous mRNA molecules may be 5 '-end capped generating a 5'-ppp-5'- triphosphate linkage between a terminal guanosine cap residue and the 5 '-terminal transcribed sense nucleotide of the mRNA molecule. This 5'-guanylate cap may then be methylated to generate an N7- methyl-guanylate residue. Poly-A tails: During RNA processing, a long chain of adenine nucleotides (poly-A tail) may be added to a polynucleotide such as an mRNA molecules in order to increase stability. Immediately after transcription, the 3' end of the transcript may be cleaved to free a 3' hydroxyl. Then poly-A polymerase adds a chain of adenine nucleotides to the RNA. The process, called polyadenylation, adds a poly-A tail that can be between, for example, approximately 100 and 250 residues long.

Untranslated regions: As used herein, the term "Untranslated regions" or UTRs of a gene refers to regions that are transcribed but not translated. The 5'UTR starts at the transcription start site and continues to the start codon but does not include the start codon; whereas, the 3'UTR starts immediately following the stop codon and continues until the transcriptional termination signal. The regulatory features of a UTR can be incorporated into the polynucleotides, primary constructs and/or mRNA of the present disclosure to enhance the stability of the molecule.

3'UTR: As used herein, unless indicated otherwise or contradictory in context, the term "3'UTR" or "three prime untranslated region" refers to the section of messenger RNA that immediately follows the translation termination codon. The 3 -UTR often contains regulatory regions that post-transcriptionally influence gene expression.

5'UTR: As used herein, unless indicated otherwise or contradictory in context, the term "5'UTR" or "five prime untranslated region" refers to the section of mRNA that starts at the transcription start site and continues to the start codon but does not include the start codon. There is growing body of evidence about the regulatory roles played by the UTRs in terms of stability of the nucleic acid molecule and translation. Natural 5'UTRs bear features which play roles in for translation initiation. 5 'UTR also have been known to form secondary structures which are involved in elongation factor binding.

Complementary DNA: As used herein, the term "complementary DNA" or "cDNA" refers to a DNA molecule containing an eukaryote gene which has been tailored or engineered to be expressed in a prokaryote host cell. cDNA is also called "intron-free" DNA as it lacks the gene regions encoding introns, its transcription yielding an intron-free mRNA molecule.

Vector : As used herein, unless indicated otherwise or contradictory in context, the term "vector" is used in its most general meaning and refers to any intermediary vehicle for a nucleic acid which enables said nucleic acid, for example, to be introduced into prokaryotic and/or eukaryotic cells and, where appropriate, to be integrated into a genome. Vectors of this kind are preferably replicated and/or expressed in the cells. Vectors may comprise plasmids, phagemids, bacteriophages or viral genomes.

Plasmid: As used herein, unless indicated otherwise or contradictory in context, the term "plasmid" refers to a double-stranded (which may be circular) DNA sequence that is capable of automatically replicating in a host cell.

When water is the solvent, the solvate is referred to as a "hydrate". In one embodiment, the pharmaceutically acceptable solvate is not a naturally occurring solvate.

Pharmaceutically acceptable isotopically-labelled compounds: In one example, the present invention also includes all pharmaceutically acceptable isotopically-labelled derivatives, which are identical to the compounds, substances, combinations or associations described herein but wherein one or more atoms are replaced by atoms having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that may be incorporated into GFR-binding compound(s) as defined herein include isotopes of hydrogen, carbon, chlorine, fluorine, iodine, nitrogen, oxygen, and sulfur, such as ² H, ³ H, ¹¹ C, ¹³ C, ¹⁴ C, ³⁶ CI, ¹⁸ F, ¹²³ l, ¹³ N, ¹⁵ N , ¹⁷ 0, ¹⁸ 0, and ³⁵ S, respectively. It should be understood that compounds, substances, combinations, associations, prodrugs, and pharmaceutical acceptable salts thereof described herein which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of the invention. Certain isotopically labeled of the compounds, substances, combinations, associations, prodrugs, and salts thereof such as, for example, in certain embodiments, those incorporating a radioactive isotope such as ³ H and ¹⁴ C, are useful in drug and/or substrate tissue distribution studies. Tritium, i.e. ³ H, and carbon-14, i.e. ¹⁴ C, are particularly preferred due to their ease of preparation and detection. Further, substitution with heavier isotopes such as deuterium, i.e. ² H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example, in certain embodiments, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Isotopically labeled compounds, substances, combinations, associations, prodrugs, and salts thereof can generally be prepared by carrying out the procedures disclosed in the Schemes and/or in the Examples by substituting a readily available non-isotopically labeled reagent for an isotopically labeled reagent. Prodrugs: As used herein, unless indicated otherwise or contradictory in context, the term "prodrug" refers to a compound, substance, combination or association that is transformed in vivo to yield a compound, substance, combination or association as defined herein or a pharmaceutically acceptable salt or solvate thereof. The transformation may occur by various mechanisms, such as via hydrolysis in blood. A prodrug of a compound, substance, combination or association defined herein may be formed in a conventional manner with one or more functional groups in the compound, such as an amino, hydroxyl or carboxyl group. For example, in certain embodiments, if a compound defined herein contains a carboxylic acid functional group, a prodrug can comprise: (1 ) an ester formed by the replacement of a hydrogen of the acid group with a group such as (C1 -C6)alkyl or (C6-C10) aryl; (2) an activated ester formed by the replacement of the hydrogen of the acid group with groups such as -(CR ² )COOR', where CR ² is a spacer and R can be groups such as H or methyl and R' can be groups such as (C1 -C6)alkyl or (C6-C10) aryl; and/or (3) a carbonate formed by the replacement of the hydrogen of the acid with groups such as CHROCOOR' where R can be groups such as H or methyl and R' can be groups such as (C1 - C6)alkyl or (C6-C10)aryl. Similarly, if a compound defined herein contains an alcohol functional group, a prodrug can be formed via the replacement of the hydrogen of the alcohol with groups such as (C1 - C6)alkanoyloxymethyl or (C1 -C6)alkanoyloxyaryl or by forming an ester via condensation with, for example, in certain embodiments, an amino acid. Where a compound defined herein contains a primary or secondary amino group, a prodrug may comprise, for example, in certain embodiments, an amide formed by the replacement of one or both of the hydrogen atoms of the amino group with (C1 - C10)alkanoyl or (C6-C10)aroyl. Other prodrugs of amines are well known to those skilled in the art. Alternatively, certain compounds defined herein may themselves act as prodrugs of other compounds defined herein. Discussions regarding prodrugs and their use can be found in, for example, in certain embodiments, "Prodrugs as Novel Delivery Systems," T. Higuchi and W. Stella, Vol. 14 of the ACS Symposium Series, and Bioreversible Carriers in Drug Design, Pergamon Press, 1987 (ed. E B Roche, American Pharmaceutical Association). Examples of other prodrug types may be found in the aforementioned reference which is hereby incorporated by reference. In one particular example, alginate may be used as a carrier or matrice for the non-cyclic or cyclic GFR- binding compounds in association with the adhesion-protein-inhibitor, both as defined herein.

VII. Administration routes and procedures

Compounds, substances, pharmaceutical associations or combinations to be delivered and/or pharmaceutical, dermatological, prophylactic, diagnostic, or imaging compositions or formulations thereof in accordance with the present disclosure may be administered by any route of administration effective for preventing, treating, diagnosing, or imaging a disease, disorder, and/or condition and/or treating or alleviating at least one symptoms thereof. Suitable administration protocols include any in-vitro, in-vivo or ex-vivo administration protocol. The preferred types and routes of administration will be apparent to those of skill in the art, depending on the type of condition or disease to be prevented or treated; whether the composition is nucleic acid based, protein based, cell based or combinations or mixtures thereof; and/or the target cell/tissue. Cells, tissues or organs can be contacted ex vivo or in vitro with a pharmaceutical association or combination for uses and methods of the invention by any suitable method, including mixing or the use of a delivery vehicle. Effective in vitro or ex vivo culture conditions include, but are not limited to, effective media, bioreactor, temperature, pH and oxygen conditions that permit cell culture. An effective medium refers to any medium in which a given host cell or tissue is typically cultured. Such medium typically comprises an aqueous medium having assimilable carbon, nitrogen and phosphate sources, and appropriate salts, minerals, metals and other nutrients, such as vitamins. Cells can be cultured in conventional fermentation bioreactors, shake flasks, test tubes, microtiter dishes, and petri plates. Culturing can be carried out at a temperature, pH and oxygen content appropriate for a cell or tissue. Such culturing conditions are within the expertise of one of ordinary skill in the art.

In one aspect, the present disclosure thus also provides a method for converting a neoplastic cell into a non-neoplastic cell, in-vitro or ex-vivo as defined herein, said method comprising the administration to a neoplastic cell of an effective amount of a pharmaceutical association, combination or composition as defined herein.

Ex-vivo administration: As used herein, unless indicated otherwise or contradictory in context, the term "ex-vivo administration" refers to performing the regulatory step outside of the subject/patient, such as administering a pharmaceutical association, combination or composition as defined herein to a population of cells (e.g., neoplastic cells) removed from a subject/patient for e.g. diagnostic, analysis and/or academic purposes. ln-vivo administration: In one example, pharmaceutical, prophylactic, diagnostic, or imaging associations, combinations or compositions are administered by one or more of a variety of routes, including oral, intravenous, intramuscular, intra-arterial, intramedullary, rectal, intravaginal, intrathecal, subcutaneous, intraventricular, transdermal, intradermal, intraperitoneal, topical (e.g. by ointments, creams, powders, lotions, gels, and/or drops), buccal, enteral, mucosal, nasal, vitreal, intratumoral, sublingual, by intra-tracheal instillation, bronchial instillation, and/or inhalation, as an oral spray, nasal spray, and/or aerosol, and/or through a portal vein catheter. In one example, pharmaceutical, prophylactic, diagnostic, or imaging associations, combinations or compositions are administered by systemic intravenous injection. In one example, pharmaceutical, prophylactic, diagnostic, or imaging associations, combinations or compositions may be administered in a way which allows them to cross the blood-brain barrier, vascular barrier, or other epithelial barrier. In one most particular example, pharmaceutical, prophylactic, diagnostic, or imaging associations, combinations or compositions may be administered locally by intratumoral administration or near tumor sites. Local administration may be performed e.g. using patches, syringes, or insertion of permeable macroscopic or microscopic vesicles containing the active principle(s).

Delivery: As used herein, unless indicated otherwise or contradictory in context, the term "delivery" refers to the act or manner of delivering a compound, substance, association, combination, composition, entity, moiety, cargo or payload. Delivery Agent: As used herein, unless indicated otherwise or contradictory in context, the term "delivery agent" refers to any substance which facilitates, at least in part, the in vivo delivery of a pharmaceutical association, combination or composition defined herein to targeted cells.

Forms suitable for oral administration: A pharmaceutical association, combination or composition for uses and methods of the invention, for example, in certain embodiments, includes forms suitable for oral administration as a tablet, capsule, pill, powder, sustained release formulations, solution, suspension, or for parenteral injection as a sterile solution, suspension or emulsion. Pharmaceutical compositions suitable for the delivery of pharmaceutical associations or combinations defined herein and methods for their preparation will be readily apparent to those skilled in the art. Such compositions and methods for their preparation may be found, for example, in certain embodiments, in 'Remington's Pharmaceutical Sciences', 19th Edition (Mack Publishing Company, 1995), which is hereby incorporated by reference in its entirety. Oral administration may involve swallowing, so that the compounds or associations enters the gastrointestinal tract, or buccal or sublingual administration may be employed by which the compound enters the blood stream directly from the mouth. Formulations suitable for oral administration include solid formulations, such as tablets, capsules containing particulates, liquids, or powders; lozenges (including liquid-filled), chews; multi- and nano-particulates; gels, solid solution, liposome, films (including muco- adhesive), ovules, sprays and liquid formulations. Liquid formulations include suspensions, solutions, syrups and elixirs. Such formulations may be employed as fillers in soft or hard capsules and typically comprise a carrier, for example, in certain embodiments, water, ethanol, polyethylene glycol, propylene glycol, methylcellulose, or a suitable oil, and one or more emulsifying agents and/or suspending agents. Liquid formulations may also be prepared by the reconstitution of a solid, for example, in certain embodiments, from a sachet. The pharmaceutical associations defined herein may also be used in fast- dissolving, fast-disintegrating dosage forms such as those described in the art.

Forms suitable for parenteral administration: In one example, the pharmaceutical association, combination or composition for uses and methods of the invention may be administered by parenteral injection. Exemplary parenteral administration forms include sterile solutions, suspensions or emulsions of the pharmaceutical association defined herein in sterile aqueous media, for example, in certain embodiments, aqueous propylene glycol or dextrose. In another embodiment, the parenteral administration form is a solution. Such parenteral dosage forms can be suitably buffered, if desired. Preferred sterile solutions include sodium chloride, 0.9%, UPS solution. Injectable formulations can be sterilized, for example, in certain embodiments, by filtration through a bacterial- retaining filter, and/or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

Forms suitable for rectal and vaginal administration: Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing compositions with suitable non-irritating excipients such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient. Forms suitable for topical and/or transdermal administration: Dosage forms for topical and/or transdermal administration of a composition may include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants and/or patches. Generally, an active ingredient is admixed under sterile conditions with a pharmaceutically acceptable excipient and/or any needed preservatives and/or buffers as may be required.

Forms suitable for pulmonary administration: Dosage forms for pulmonary administration via the buccal cavity may comprise dry particles which comprise the active ingredient (e.g. the pharmaceutical association defined herein) and which have a diameter in the range from about 0.5 nm to about 7 nm. Such compositions are conveniently in the form of dry powders for administration using a device comprising a dry powder reservoir to which a stream of propellant may be directed to disperse the powder and/or using a self-propelling solvent/powder dispensing container such as a device comprising the active ingredient dissolved and/or suspended in a low-boiling propellant in a sealed container. Pharmaceutical compositions formulated for pulmonary delivery may provide an active ingredient in the form of droplets of a solution and/or suspension. Such formulations may be prepared, packaged , and/or sold as aqueous and/or dilute alcoholic solutions and/or suspensions, optionally sterile, comprising active ingredient, and may conveniently be administered using any nebulization and/or atomization device. Such formulations may further comprise one or more additional ingredients including, but not limited to, a flavoring agent such as saccharin sodium, a volatile oil, a buffering agent, a surface active agent, and/or a preservative such as methylhydroxybenzoate.

Forms suitable for nasal administration : Formulations described herein as being useful for pulmonary delivery are also useful for intranasal delivery of a pharmaceutical composition. Formulations suitable for nasal administration may, for example, in certain embodiments, comprise from about as little as 0.1 % (w/w) and as much as 100% (w/w) of active ingredient (e.g. the pharmaceutical association defined herein), and may comprise one or more of the additional ingredients described herein. A pharmaceutical composition may be prepared, packaged, and/or sold in a formulation suitable for buccal administration. Such formulations may, for example, in certain embodiments, be in the form of tablets and/or lozenges made using conventional methods, and may, for example, in certain embodiments, 0.1 % to 20% (w/w) active ingredient, the balance comprising an orally dissolvable and/or degradable composition and, optionally, one or more of the additional ingredients described herein. Alternately, formulations suitable for buccal administration may comprise a powder and/or an aerosolized and/or atomized solution and/or suspension comprising active ingredient. Such powdered, aerosolized, and/or aerosolized formulations, when dispersed, may have an average particle and/or droplet size in the range from about 0.1 nm to about 200 nm, and may further comprise one or more of any additional ingredients described herein.

Forms suitable for ophthalmic administration: Dosage forms for ophthalmic administration include, for example, in certain embodiments, eye drops including, for example, in certain embodiments, a 0.1 /1 .0% (w/w) solution and/or suspension of the active ingredient (e.g. the pharmaceutical association defined herein) in an aqueous or oily liquid excipient. Such drops may further comprise buffering agents, salts, and/or one or more other of any additional ingredients described herein. Other opthalmically- administrable formulations which are useful include those which comprise the active ingredient in microcrystalline form and/or in a liposomal preparation . Ear drops and/or eye drops are contemplated as being within the scope of this present disclosure.

Direct injection : One preferred administration method for delivering a pharmaceutical association, combination or composition as defined herein is by local administration, in particular, by direct injection . Direct injection techniques are particularly useful for administering a composition to a cell or tissue that is accessible by surgery, and particularly, on or near the surface of the body. Administration of a composition locally within the area of a target cell refers to injecting the composition centimeters and preferably, millimeters from the target cell or tissue. Dosage regimens: The dosage regimen of the pharmaceutical associations or combinations and/or pharmaceutical compositions as defined herein may be adjusted to provide the optimum desired response. For example, in certain embodiments, a single bolus may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. The appropriate dosing regimen, the amount of each dose administered and/or the intervals between doses will depend upon the pharmaceutical association being used, the type of pharmaceutical composition, the characteristics of the subject in need of treatment and the severity of the condition being treated. Thus, the skilled artisan would appreciate, based upon the disclosure provided herein, that the dose and dosing regimen is adjusted in accordance with methods well-known in the therapeutic arts. That is, the maximum tolerable dose can be readily established, and the effective amount providing a detectable therapeutic benefit to a patient may also be determined, as can the temporal requirements for administering each agent to provide a detectable therapeutic benefit to the patient. Accordingly, while certain dose and administration regimens are exemplified herein, these examples in no way limit the dose and administration regimen that may be provided to a patient in practicing the present invention. In general, pharmaceutical compositions in accordance with the present disclosure may be administered at dosage levels sufficient to deliver from about 0.0001 mg/kg to about 100 mg/kg, from about 0.01 mg/kg to about 50 mg/kg, from about 0.1 mg/kg to about 40 mg/kg, from about 0.5 mg/kg to about 30 mg/kg, from about 0.01 mg/kg to about 10 mg/kg, from about 0.1 mg/kg to about 10 mg/kg, or from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic, diagnostic, prophylactic, or imaging effect. The desired dosage may be delivered three times a day, two times a day, once a day, every other day, every third day, every week, every two weeks, every three weeks, or every four weeks. In certain embodiments, the desired dosage may be delivered using multiple administrations (e.g., two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, or more administrations). It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that dosage ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the present invention. For example, in certain embodiments, doses may be adjusted based on pharmacokinetic or pharmacodynamic parameters, which may include clinical effects such as toxic effects and/or laboratory values. Thus, the present invention encompasses intra-patient dose-escalation as determined by the skilled artisan. Determining appropriate dosages and regiments for administration of the chemotherapeutic agent are well-known in the relevant art and would be understood to be encompassed by the skilled artisan once provided the teachings disclosed herein.

Effective dose parameters: The dosage regimen of the pharmaceutical associations or combinations and/or pharmaceutical compositions as defined herein may be adjusted to obtain effective dose parameters. Effective dose parameters can be determined using methods standard in the art for a particular disease or condition. In particular, the effectiveness of dose parameters of a therapeutic composition as defined herein when treating cancer can be determined by assessing response rates. Such response rates refer to the percentage of treated patients in a population of patients that respond with either partial or complete remission. Remission can be determined by, for example, in certain embodiments, measuring tumor size or microscopic examination for the presence of cancer cells in a tissue sample. A pharmaceutical composition as defined herein may be prepared, packaged, or sold in bulk, as a single unit dose, or as a plurality of single unit doses.

Unit dose: As used herein, unless indicated otherwise or contradictory in context, the term "unit dose" refers to a discrete amount of the pharmaceutical composition comprising a predetermined amount of the active ingredient. The amount of the active ingredient is generally equal to the dosage of the active ingredient which would be administered to a subject or a convenient fraction of such a dosage such as, for example, in certain embodiments, one-half or one-third of such a dosage. Single unit dose: As used herein, unless indicated otherwise or contradictory in context, the term "single unit dose" refers to a dose of any therapeutic association or composition administered in one dose/at one time/single route/single point of contact, i.e., single administration event.

Split dose: As used herein, unless indicated otherwise or contradictory in context, the term "split dose" refers to the division of single unit dose or total daily dose into two or more doses.

Total daily dose: As used herein, unless indicated otherwise or contradictory in context, the term "total daily dose" refers to an amount given or prescribed in 24hr period. It may be administered as a single unit dose.

The relative amounts of the active ingredient(s), the pharmaceutically acceptable excipients, carriers or vehicles, and any additional ingredients in a pharmaceutical composition defined herein will vary, depending upon the identity, size, and condition of the subject treated and further depending upon the route by which the composition is to be administered. In addition to the active ingredient, a pharmaceutical composition of the invention may further comprise one or more additional pharmaceutically active agents.

Combination therapy: Compounds, associations, compositions or formulations defined herein may be used in combination with one or more other therapeutic, prophylactic, diagnostic, or imaging agents. As used herein, the term "in combination with" is not intended to imply that the agents must be administered at the same time and/or formulated for delivery together, although these methods of delivery are within the scope of the present disclosure. Compounds, associations, compositions or formulations can be administered concurrently with, prior to, or subsequent to, one or more other desired therapeutics or medical procedures. In some embodiments, they are administered within about 90, 60, 30, 15, 10, 5, or 1 minute of one another. In some embodiments, the administrations of the agents are spaced sufficiently closely together such that a combinatorial (e.g., a synergistic) effect is achieved. In general, each agent will be administered at a dose and/or on a time schedule determined for that agent. In one example, the present disclosure encompasses the delivery of pharmaceutical, prophylactic, diagnostic, or imaging compositions in combination with agents that improve their bioavailability, reduce and/or modify their metabolism, inhibit their excretion, and/or modify their distribution within the body. It will further be appreciated that therapeutically, prophylactically, diagnostically, or imaging active agents used in combination may be administered together in a single composition or administered separately in different compositions. In general, it is expected that agents used in combination with be used at levels that do not exceed the levels at which they are used individually. In one example, the levels used in combination will be lower than those utilized individually. The particular combination of therapies to employ in a combination regimen will take into account compatibility of the desired therapeutics and/or procedures and the desired therapeutic effect to be achieved. It will also be appreciated that the therapies employed may achieve a desired effect for the same disorder (For example, in certain embodiments, a composition useful for treating cancer in accordance with the present disclosure may be administered concurrently with a chemotherapeutic agent), or they may achieve different effects (e.g., control of any adverse effects).

In certain embodiments, said adhesion protein inhibitor may be, separately from said GFR-binding compound, administered locally to the tumor or cancer site using appropriate means such as by injection or by incision, using one administration technique and said GFR-binding compound may then be administered locally (immediately or not) using another administration technique to the same tumor or cancer site.

In one aspect, the present disclosure thus provides at least one GFR-binding compound as defined herein for use in the prevention, diagnostic and/or treatment of a neoplastic disease in association or combination with at least one adhesion protein or molecule inhibitor as defined herein.

Also provided is a method of treating a neoplastic disease, comprising administering to a subject in need thereof an effective amount of at least one GFR-binding compound as defined herein in association or combination with at least one adhesion protein or molecule inhibitor as defined herein. Although the descriptions of pharmaceutical associations, combinations or compositions provided herein are principally directed to pharmaceutical associations, combinations or compositions which are suitable for administration to mammals, in particular humans, it will be understood by the skilled artisan that such compositions are generally suitable for administration to animals of all sorts, in particular to any member of the Vertebrate class. Modification of pharmaceutical compositions suitable for administration to humans in order to render the compositions suitable for administration to various animals is well understood, and the ordinarily skilled veterinary pharmacologist can design and/or perform such modification with merely ordinary, if any, experimentation. Subjects to which administration of the pharmaceutical compositions is contemplated include, but are not limited to, humans and/or other primates; mammals, including commercially relevant mammals such as cattle, pigs, horses, sheep, cats, dogs, mice, and/or rats; and/or birds, including commercially relevant birds such as chickens, ducks, geese, and/or turkeys.

In certain aspects, a pharmaceutical association, combination or composition as defined herein is thus useful in the protection of a subject/patient from (e.g. in the treatment and/or prevention of) a neoplastic disease, condition, disorder or pathology and/or at least one symptom thereof such as tumors and cancers.

In one aspect, the present disclosure provides a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein for use in a method of non- mutagenically protecting a subject from a neoplastic disease i.e. without modifying or altering the genome of the treated neoplastic cells. Also provided is a method of non-mutagenically protecting a subject from a neoplastic disease i.e. without modifying or altering the genome of the treated neoplastic cells, comprising administering to a subject in need thereof an effective amount of a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein.

In one aspect, the present disclosure provides a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein for use in a method of extracellular treatment of a neoplastic disease, disorder, condition, pathology, or any symptoms thereof. Also provided is a method of extracellular treatment of a neoplastic disease, disorder, condition, pathology, or any symptoms thereof, comprising administering to a subject in need thereof an effective amount of a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition as defined herein. An extracellular treatment as used herein implies at least one (in particular, all) biological action/effect to be provided or to occur outside the cell to be treated (i.e. a neoplastic cell). In other words, the biologically active agent (e.g. the pharmaceutical association, combination or composition as defined herein) delivers/provides its biological/pharmaceutical effect to the outside of the cell (e.g. on the cell's surface) without the need to penetrate through the cell membrane, inside the neoplastic cell to be treated. Once the extracellular action/effect has been administered/delivered to the neoplastic cell to be treated, said active agent may be, for instance, excreted from the host organism with or without being metabolised, and/or tagged to be destroyed through apoptotic routes, and/or internalised by nearby cells, etc... Without being bound to any specific theory, it is believed that once the extracellular biological action/effect/message/signal has been delivered by the pharmaceutical association or composition defined herein to a neoplastic cell to be treated, said cell then undergo self-healing into a functional , healthy, non-neoplastic cell.

Data have shown (FIGURE 6) that the administration or action of the pharmaceutical association or composition as defined herein on neoplastic cells to be treated, implicates and down-regulates (in particular, reduces, substantially reduces or suppress) the Ras/MAP kinase, FAK Src kinase and/or PIP2 signalling pathways. Without wishing to be bound to any specific theory, it is conventionally known that these pathways control the expression of cyclins D, which in turn controls the activity of CDKs 4 and/or 6 so that down-regulating (in particular, reducing, significantly reducing or suppressing) the Ras/MAP kinase, FAK/Src kinase and/or PIP2 pathways would inhibit, reduce, damper or suppress the expression of cyclins D and/or CDK4 and CDK6 and/or the formation of the cyclins D-CDK4/6 complexes. As already stated herein, cell cycle comprises four main phases: The S phase for DNA duplication, followed by a G2 phase for preparation of the entry into the M phase, the M or mitotic phase wherein the cell divides and finally the G1 phase for cell growth. During the G1 phase the cell makes decisions on whether to continue the cell cycle and undergo cell growth and further divide, or to exit the cycle in the GO phase and remains quiescent, die or initiate differentiation. The progression through the cell cycle is governed by phosphorylation signals emitted by different bimolecular complexes composed of CDKs and cyclin proteins, both as defined herein.

The cyclin D-CDK4/6 complexes are capable of leading a cell through the restriction (R)-point which is generally known for controlling the passage of the cell from the G1 phase to the S phase of the cell cycle. This control gate is generally thought to be located at the end of the cell cycle's G 1 phase, just before entry into S phase, and is involved in the decision of whether the cell should divide or proliferate, delay division, or enter the GO resting state.

This control gate ensures that a series of surveillance or monitoring mechanisms are completed successfully before proceeding through to the next phase. These monitoring mechanisms are also commonly termed "checkpoints" or "checkpoint controls". If a checkpoint is not validated by the control gate, the cell should halt further advance through the cell cycle and enter the GO phase. However, neoplastic cells, such as cancer cells, have developed mechanisms that somehow "disconnect" or "impair" one or more checkpoints from the control gate so that the cell is "tricked to "believe that all checkpoints are validated (or, in other words, "tricked to ignore" the non-validated status of relevant checkpoints) and thus never or rarely enter into the GO phase.

Without wishing to be bound to any specific theory, it is thought that the pharmaceutical associations, combination or composition as defined herein can restore or re-establish (the integrity of) one or more impaired cell cycle checkpoints so as to restore the lost ability of a neoplastic cell to detect a malfunction or a defect in the cell cycle regulation, induce the cell cycle arrest and exit the cell cycle in GO. One particular checkpoint that the present invention is able to restore is the cell adhesion checkpoint. In one aspect, the present disclosure provides a pharmaceutical association, combination or (therapeutic, dermatologic, ophthalmologic, diagnostic, etc.) composition defined herein for use in a method of treating a neoplastic cell or a neoplastic disease by restoring the cell adhesion checkpoint of said neoplastic cell.

The cell adhesion checkpoint is known to be in charge of monitoring the cells attachments to the extracellular matrix (ECM). When a cell does not detect a "correct" attachment it should halt further advance through the cell cycle and enter the Go phase. The ECM attachment is normally achieved via cell transmembrane proteins, such as the integrins, syndecans and different proteoglycans. The most important among these are the integrins, which assemble as alpha-beta heterodimers. In addition to physically linking the cell to the extracellular matrix, the binding of the extracellular integrin domains to specific components of the ECM activates the integrins and allows binding of different signalling molecules to its intracellular domain. This activates various signalling pathways that mediate signals to the adhesion checkpoint including the Ras/MAP kinase, FAK/Src kinase, and PIP2 pathways. These pathways are involved in the regulation of the expression of cyclins D, which in turn controls the activity of CDK4/6. The cyclins D-CDK4/6 complexes are capable of leading the cell through the R-point gate.

Data have also shown (FIGURES 6 and 7) that the administration or action of the pharmaceutical association or composition as defined herein on neoplastic cells to be treated down-regulated (in particular, substantially reduced) the expression of FAK genes and proteins and/or MAP kinase and/or reduced (in particular, substantially reduced) the expression or activity of GTPase Ras, Rho (Rho, Rac, Cdc42).

Focal adhesions are integrin-containing, multi-protein structures that can form mechanical links between the intracellular actin bundles and the extracellular substrate in many cell types. Focal adhesions are highly dynamic structures that grow or shrink due to the turnover of their component proteins in response to changing mechanical stresses (e.g. actomyosin-generated forces, external forces exerted by or through the surrounding matrix). Focal adhesions are consistently found at the end of stress fibers and are therefore highly integrated with the bulk of the cytoskeleton. Consequently, focal adhesions serve to transmit force, internally generated by the cytoskeletal network, to the ECM and vice versa vian adhesion receptors. Adhesion assembly and maturation are highly dependent on the presence of force, which is believed to instigate structural rearrangements that in turn foster the recruitment of additional proteins (growth) and induce signaling cascades leading to actin polymerization (strengthening). Focal adhesions serve as a biochemical signaling hub to concentrate and direct numerous signaling proteins as part of signal transduction cascades at sites of integrin binding and clustering.

Focal Adhesion Kinase (FAK) is a cytoplasmic tyrosine kinase that plays a role in integrin-mediated signal transductions and also participates in signalling via other cell surface receptors. FAK is typically located in structures known as focal adhesions. These are multi-protein structures that link the extracellular matrix (ECM) to the cytoplasmic cytoskeleton. FAK is known to be phosphorylated in response to integrin engagement, growth factor stimulation, and the action of mitogenic neuropeptides. This cytosolic kinase has been reported to participate to diverse cellular mechanisms including cell locomotion, mitogen response and cell survival. FAK has four defined regions, or tertiary structure domains. Two of these domains, the N-terminal FERM domain and the Kinase domain, form an auto-inhibitory interaction. This interaction is thought to be the result of hydrophobic interactions between the two domains and prevents the activation of the Kinase domain, thereby preventing the signalling function of FAK. Release of this auto-inhibitory interaction has been shown to occur within focal adhesions but not in the cytoplasm and therefore is thought to require interaction with focal adhesion proteins.

MAP kinase Mitogen-activated protein kinases or MAP kinases (or MAPK) include a large group of related serine/threonine eukaryotic protein kinases whose regulatory cell functions include proliferation, gene expression, differentiation, mitosis, cell survival, and apoptosis. All have been reported to become activated when they have been phosphorylated at a Tyrosine and a Threonine amino acid. MAP kinases are catalytically inactive in their basic form. In order to become active, (potentially multiple) phosphorylation events is required to occur in their activation loops. MAP kinases typically form multi-step pathways, receiving input signals at several levels above the actual MAP kinase. These pathways can effectively convey stimuli from the cell membrane to the nucleus or to many other subcellular targets.

GTPases (singular GTPase) are a large family of hydrolase enzymes that can bind and hydrolyze guanosine triphosphate (GTP). The GTP binding and hydrolysis takes place in the highly conserved G domain common to all GTPases. The hydrolysis of the γ phosphate of GTP into guanosine diphosphate (GDP) and Pi, inorganic phosphate, occurs by the SN2 mechanism of nucleophilic substitution via a pentavalent intermediate state and is dependent on the magnesium ion Mg ²⁺ . Regulatory GTPases, also called the GTPase superfamily, are GTPases used for regulation of other biochemical processes. Most prominent among the regulatory GTPases are the G proteins. Small GTPases have a molecular weight of about 21 kDa and generally serve as molecular switches for a variety of cellular signalling events.

According to their primary amino acid sequences and biochemical properties, the Ras superfamily is further divided into five subfamilies: Ras, Rho, Rab, Arf and Ran. The Rho subfamily is further divided into RHOA, RAC1 , and CDC42. Ras/MAP kinase signalling pathway (also known as the Ras-Raf-MEK-ERK pathway) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell. The signal starts when a signalling molecule binds to the receptor on the cell surface and ends when the DNA in the nucleus expresses a protein and produces some change in the cell, such as cell division. The pathway includes many proteins, including MAPK (mitogen-activated protein kinases, originally called ERK, extracellular signal-regulated kinases), which communicate by adding phosphate groups to a neighbouring protein.

The FAK/Src kinase signalling pathway involves focal adhesion kinase (FAK) and steroid receptor coactivator (Src) which are intracellular (non-receptor) tyrosine kinases that physically and functionally interact to promote a variety of cellular responses. The linked activities of these two kinases are a common intracellular point of convergence in the signalling initiated by the integrin-extracellular matrix (ECM) interaction. Integrins, a family of transmembrane receptors, interact with the ECM and the intracellular actin-cytoskeleton. The integrins cluster upon binding to the ECM to form focal adhesion (FA) contacts. In response to this clustering, FAK associates to the cytoplasmic tail of the integrins and undergoes phosphorylation at its tyrosine 397 residue (Y397). This phosphorylated tyrosine provides a docking site for Src which is then able to phosphorylate additional sites on FAK, leading to a further increase in FAK activity and allowing the recruitment of proteins that contain Src homology 2 (SH2) domains such as Grb2 and PI3K.The mutually activated FAK/Src complex then initiates a cascade of phosphorylation events of new protein-protein interactions to trigger several signalling pathways that eventually leads to different cellular responses. Phosphatidylinositol 4,5-bisphosphate or PIP2 is a minor phospholipid component of cell membranes. PIP2 is enriched at the plasma membrane where it is a substrate for a number of important signalling proteins. PIP2 is phosphorylated by the Class I PI 3-kinases. Class I PI 3-kinases are a subgroup of the enzyme family, phosphoinositide 3-kinase that possess a common protein domain structure, substrate specificity, and method of activation. Class I PI 3-kinases are further divided into two subclasses, class IA PI 3-kinases and class IB PI 3-kinases. Class IA PI 3-kinases are activated by receptor tyrosine kinases (RTKs). Class IB PI3-kinases are activated by G-protein-coupled receptors (GPCRs). After their activation these kinases phosphorylate PIP2 to form phosphatidylinositol (3,4,5)-trisphosphate PIP3. Both PIP2 and PIP3 not only act as substrates for enzymes but also serve as docking phospholipids that bind specific domains that promote the recruitment of proteins to the plasma membrane and subsequent activation of signalling cascades. PIP3 functions to activate downstream signalling components, the most notable one being the protein kinase AKT, which activates downstream anabolic signalling pathways required for cell growth and survival.

Paxillin is a signal transduction adaptor protein. The C-terminal region of paxillin contains four LI domains that target paxillin to focal adhesions through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal region of paxillin is rich in protein-protein interaction sites. The proteins that bind to paxillin are diverse and include protein tyrosine kinases, such as Src and focal adhesion kinase (FAK), structural proteins, such as vinculin and actopaxin, and regulators of actin organization, such as COOL/PIX and PKL/GIT. Paxillin is tyrosine-phosphorylated by FAK and Src upon integrin engagement or growth factor stimulation, creating binding sites for the adapter protein Crk.

Vinculin is a focal adhesion protein that is involved in linkage of integrin adhesion molecules to the actin cytoskeleton. Vinculin is a cytoskeletal protein associated with cell-cell and cell-matrix junctions, where it is thought to function as one of several interacting proteins involved in anchoring F-actin to the membrane. Vinculin is a 117-kDa cytoskeletal protein of 1066 amino acids. The protein contains an acidic N-terminal domain and a basic C-terminal domain separated by a proline-rich middle segment. Vinculin consists of a globular head domain that contains binding sites for talin and a-actinin as well as a tyrosine phosphorylation site, while the tail region contains binding sites for F-actin, paxillin, and lipids.

Data have also shown (FIGURE 5) that the administration or action of the pharmaceutical association, combination or composition as defined herein on neoplastic cells to be treated increased the phosphorylation of the protein p53.

Data have also shown (FIGURE 5) that the administration or action of the pharmaceutical association, combination or composition as defined herein on neoplastic cells to be treated down-regulated (in particular, substantially decreased or suppressed) the phosphorylation of the protein pRb.

Data have also shown (FIGURE 6) that the administration or action of the pharmaceutical association, combination or composition as defined herein on neoplastic cells to be treated down-regulated the protein Src.

Tumor protein p53, also known as p53, cellular tumor antigen p53, phosphoprotein p53, or tumor suppressor p53, is a protein that in humans is encoded by the TP53 gene. The p53 protein is involved in multicellular organisms, where it regulates the cell cycle and, thus, functions as a tumor suppressor, generally preventing neoplastic diseases such as cancers. As such, p53 has been described as "the guardian of the genome" because of its role in conserving stability by preventing genome mutation. TP53 is thus said to be a tumor suppressor gene. Src is a non-receptor protein tyrosine kinase that plays a multitude of roles in cell signalling. Src is involved in the control of many functions, including cell adhesion, growth, movement and differentiation. Src is widely expressed in many cell types, and can have different locations within a cell. It appears that the subcellular location of Src can affect its function. Src can associate with cellular membranes, such as the plasma membrane, the perinuclear membrane and the endosomal membrane. At the plasma membrane, Src can transduce signals from a variety of receptors to internal signalling pathways that convey these signals to the nucleus, cytoskeleton and other cellular components. For example, Src can act through growth factor receptors to affect cell growth and proliferation. Within the nucleus, Src is thought to help regulate the cell cycle and cell division by its interactions with other proteins. For example, Src can interact with Sam68 to help regulate gene expression. In bone osteoclasts, Src acts to regulate the respiratory enzyme cytochrome C oxidase (Cox), where Src-induced phosphorylation of Cox is required for maintaining high levels of ATP to meet the cells' high energy requirements. Src can also be found in the cytoplasm, and between cells at adherens junctions, where it takes on different roles. pRb (Retinoblastoma protein) is a tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. It is also a recruiter of several chromatin remodeling enzymes such as methylases and acetylases. Rb restricts the cell's ability to replicate DNA by preventing its progression from the G1 (first gap phase) to S (synthesis phase) phase of the cell cycle. Rb binds and inhibits transcription factors of the E2F family, which are composed of dimers of an E2F protein and a dimerization partner (DP) protein. When Rb is bound to E2F, the complex acts as a growth suppressor and prevents progression through the cell cycle. Rb is phosphorylated to pRb by certain Cyclin Dependent Kinases (CDKs). pRb is described as being hyperphosphorylated and when in this state, it is unable to complex E2F and therefore, unable to restrict progression from the G1 phase to the S phase of the cell cycle. During the M- to-G1 transition, pRb is progressively dephosphorylated by PP1 , returning to its growth-suppressive hypophosphorylated state Rb.

Accordingly, it is possible to achieve the conversion of a neoplastic cell (e.g. a cancer cell) into a non- neoplastic cell (e.g. a functional and/or healthy cell of the bone, chondrocytic, muscle, vascular, neuronal, retinal, renal, ligament, tendon, fibroblast, blood, lung, adipocyte, reproduction system cell lineages) using extracellular, non-mutagenic active principles and is thus useful in the treatment of neoplastic diseases such as cancers. The present invention provides a recoding therapy for the treatment of neoplastic diseases, conditions or disorders such as cancer and aims at providing a suitable micro-environment to the neoplastic cell containing suitable biological signals so that the neoplastic cell is able to undergo self-healing and become a functional, healthy, non-neoplastic cell. In addition, it has been found that using the recoding therapy of the invention instead of conventional therapies allows for improved treatment selectivity in such a way that reduced or substantially no adverse side-effect is observed. Without wishing to be bound to any specific theory, this may be explained by considering that the present therapy relies on the activation of physiological cell mechanisms without imposing or forcing the treated cell to undergo e.g. apoptosis or cell cycle arrest (which would then most likely unselectively target any cells, healthy and neoplastic) but instead reestablishes the correct cellular microenvironment surrounding this neoplastic cell so that the cell is able to operate self-healing. As a result, a non-neoplastic cell i.e. a cell in which the cell cycle and/or cell adhesion checkpoint(s) need not be repaired, brought in contact with such a microenvironment would be less or not be substantially affected.

Remarkably, it has also been found that using the pharmaceutical associations or compositions as defined herein allows for the reduction (in most cases, important reduction) of the time of treatment of a neoplastic cell and by extension of a neoplastic disease in comparison with known technologies.

It is another aspect of the present invention to solve the technical problem of providing a therapy for treating neoplastic diseases being completely or at least partially devoid of one or more, preferably a plurality of the disadvantages of known treatments.

All combinations of any of the above-mentioned features described in all above part of the present description are specifically contemplated by the Applicant to be within the scope of the present invention unless contradictory in context.

The following general methods were used:

Immunostaining:

The cells were first fixed for 20 min with 4% paraformaldehyde/PBS at 4°C. After fixation, the cells were permeabilized in PBS containing 1 % Triton X-100 for 15 min. Protein immunofluorescent visualization was performed by first treating the cells with 1 % (v/v) specific monoclonal antibodies for 1 hour at 37 °C. Then the samples were incubated with Alexa fluor® 568 or 647 (F(ab')2 fragment of lgG(H + L)) during 30 min at room temperature. The cell nuclei were counterstained in 20 ng/mL DAPI for 10 min at room temperature.

Quantification of positive contact numbers and areas:

For this type of quantification the freeware image analysis ImageJ® software was used. The raw image was first converted to an 8-bit file, and then the unsharp mask feature was used (settings 1 :0.2) to remove the image background (rolling ball radius 10). After smoothing, the resulting image, which appears similar to the original photomicrograph but with minimal background, was then converted to a binary image by setting a threshold. Threshold values were determined empirically by selecting a setting, which gave the most accurate binary image for a subset of randomly selected photomicrographs. The cell area was determined by manual delineation on raw fluorescent images. Total contact area and mean contact area per cell were calculated by "analyse particules" in ImageJ®. A minimum of 50 cells per condition were analyzed.

Quantitative Real Time Polymerase Chain Reaction (RT-PCR):

After 24 hours of culture, total RNA was extracted by using the RNeasy total RNA kit (Qiagen®) according to the manufacturer's instructions. Purified total RNA was used as a template in order to make cDNA by a reverse transcription reaction (Gibco Brl®) with random primers (Invitrogen®). The cDNA was then used as a template for a real-time PCR amplification in the presence of SYBR green reagents (Bio- Rad®) by using a thermocycler (iCycler, Biorad®). Data were analyzed with the iCycler IQ ^TM ® software and compared by the AACt method. Briefly, the mean Ct value of the target gene was normalized to its averaged Ct values of the housekeeping gene (GAPDH) to give a ACt value, which was then normalized to a control sample to obtain a AACt value. The results were obtained from two series of experiments performed in triplicate.

- Western Blot:

After 24 hours of culture, cells were permeabilized (10% SDS, 25 mM NaCI, 10 nM pepstatin and 10 nM leupeptin in distilled water and loading buffer), boiled for 10 minutes and resolved by reducing PAGE (Invitrogen). Proteins were transferred onto nitrocellulose, blocked, and labeled with HRP-conjugated antibodies (Invitrogen). Integrin av, a5, a3, a4, β1 , β3, β5, β9, phosphorylated ERK, phosphorylated Src Kinase, PDK1 and phosphorylated pRB and p53 were blotted by treating the nitrocellulose with monoclonal anti-integrin (extracellular domain) av, a5, a3, a4, β1 , β3, β5 and β6 antibodies (Santa Cruz Biotechnology). Phospho-Smad1/5/8 was blotted by treating the nitrocellulose with monoclonal anti-p- Smad1/5/8 (Santa Cruz Biotechnology). For all of the experiments the western blot was performed in triplicate, along with an additional blot for actin and coomassie blue staining to ensure constant protein load among samples. An integrins a3, av, a5 shRNAs, integrins β1 , β3 shRNAs, Syndecans 1 , 4 were obtained from Santa Cruz Biotechnology. - Statistical Analysis:

In terms of real-time PCR assay, all of the data were expressed as mean ± standard error, and analyzed statistically by the paired Student's t test method.

Covalent association with polymers (such as PET or PEEK)

The polymer used in this study is poly(ethylene terephthalate) (PET). The polymers were first treated in order to create -COOH (carboxyl) functions on the PET surfaces from -OH (hydroxyl) functions. Next, the PET-COOH samples were immersed in a solution of dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (EDC, 0.2 M) + N-hydroxysuccinimide (NHS, 0.1 M) in 2-(N-morpholino)-ethanesulfonic acid (MES) buffer (0.1 M in MilliQ water) and the samples were rinsed in MilliQ water (50 ml_ for 30 min). Finally, the covalent immobilization of the compounds (e.g. peptides) was achieved by using a solution of compound/1X PBS (C = 10 ³ M) incubated for 18 hours at room temperature. After grafting, the materials were rinsed in MilliQ water (100 ml) for 1 week.

Example 1 : Osteosarcoma recoding

Pharmaceutical associations according to certain embodiments of the present disclosure were added to tumor cells, hereinafter osteosarcoma cells. Human osteosarcoma cells were obtained from ATCC®. Tumor cells were then cultured in Dulbecco's Modified Eagle Medium (DMEM, Invitrogen®) supplemented with 10% (v/v) fetal bovine serum (FBS), 1 % penicillin/streptomycin and incubated in a humidified atmosphere containing 5% (v/v) C0 ₂ at 37°C. All of the cell culture experiments were performed without any serum in the medium for the first 8 hours of culture. All cells were used at a low passage number (≤ passage 10), were subconfluently cultured and were seeded at 10 000 cells/cm ² for the purpose of the experiments.

The cell phenotype was analyzed after 24 hours of cell culture. The human sarcoma cells adhere, spread, and differentiate into osteocyte cells as confirmed by analysis of DMP-1 (Dentin matrix acidic phosphoprotein 1 ), Sclerostin and RANK-L (receptor activator of nuclear factor kappa B ligand) expression (FIG. 1 ). During cell recoding, osteosarcoma cells undergo important changes in their cell morphology such as cell shape modification, cell body size reduction and increase in cell processes in order to obtain the characteristic osteocyte morphology. These cells presented a characteristic dendritic- like morphology, a total reduction in cell body volume of around 50% and expressed a set of known osteocytic markers. These results demonstrate that pharmaceutical associations according to certain embodiments of the present disclosure induce the recoding of human osteosarcoma cells into osteocytes in a short period of time (24 hours).

All cell culture experiments were carried out without any serum in the medium for the first 8 hours of culture. All cells were used at a low passage number (< passage 1 0), were subconfluently cultured and were seeded at 1 0 000 cells/cm ² for the purpose of the experiments.

It was observed that these tumor cells cultured in the presence of pharmaceutical associations according to certain embodiments of the present disclosure were converted into epithelial cells (fibrocyte like-cells) by analyzing the expression of the fibrocytic biomarkers MMP-9, Vimentin and a-SMA. An increased expression of these genes was observed after 24 hours of culture (FIG. 4) as characterized using Quantitative Real Time PCR as described in the Methods section.

Example 5: Recoding of neoplastic cells indicated by significantly reduced proliferation markers

Neoplastic cells (in this example osteosarcoma cells) were cultured in the presence of pharmaceutical associations according to certain embodiments of the present disclosure. A rapid (24 hours) decrease of the tumor markers was observed (FIG. 5). The adhesion checkpoint then activates the tumor suppressor proteins p53 and pRB. It was observed that, in tumor cells cultured in the presence of pharmaceutical associations according to certain embodiments of the present disclosure, the expression of p53 decreases as demonstrated by quantification of protein expression level (immunofluorescence staining and quantification using ImageJ as described in the general methods section) (FIG. 5A) and the pRB is dephosphorylated as demonstrated by a quantification of protein phosphorylation level (immunofluorescence staining and subsequent quantification by using the ImageJ software as described in the general methods section) (FIG. 5B).

The main signaling pathways include: Ras/MAP kinase, FAK/Src kinase and PIP2 which are decreased after 24 hours as shown by western blot quantifications (FIG. 6). This demonstrated by the absence of phosphorylation at Thr202 and Tyr204 on ERK (FIG. 6A). Moreover, no phosphorylation at Thr416 but phosphorylation of Tyr527 was observed on Src kinase (FIG. 6B). Finally, a decrease of 3-phosphoinositide-dependent protein kinase 1 (PDK1 ) protein expression was also was observed (FIG. 6C).

These data indicate the entry of the cells into GO quiescence phase.

Example 9: Growth factor receptor activation

Table 9

Example 11 : The presence of adhesion components in the extracellular microenvironment inhibits the cell conversion

In order to demonstrate the importance of adhesion proteins inhibition in the recoding process of a neoplastic cell, a PET substrate was covalently functionalized with RGD peptides (the primary integrin recognition site present in many ECM proteins (e.g., fibronectin)) and an exemplary GFR-binding compound according to the present disclosure using methods already described herein.

This modified substrate was then cultured with human osteosarcoma cells from ATCC® in Dulbecco's Modified Eagle Medium (DMEM , Invitrogen®) supplemented with 10% (v/v) fetal bovine serum (FBS), 1 % penicillin/streptomycin and incubated in a humidified atmosphere containing 5% (v/v) C0 ₂ at 37°C. All cell culture experiments were performed without any serum in the medium for the first 8 hours of culture. All cells were used at a low passage number (< passage 10), were subconfluently cultured and were seeded at 10 000 cells/cm ² for the purpose of the experiments. As shown in FIG. 9A and 9B, the presence of covalently immobilized components favorising the adhesion inhibited the process of recoding of the osteosarcoma cells into osteocytes as characterized by RT-PCR and cell morphology observation.

It was also confirmed that the presence of RGD peptides did not modify the density of covently grafted GFR-binding compounds. Indeed, it was observed that the GFR-binding compound density was stable (around 1 .36 pmol/mm ² ) with or without RGD peptides (FIG. 9C).

It was also shown that the RGD peptides interacted specifically with integrin α3β1 . Indeed, inhibition of α3β1 , α5β3 and ανβ3 integrins (i.e., the three predominant receptor dimers involved in binding ECM molecules containing RGD motifs for the osteosarcoma cells) by specific antibodies, indicated that cells predominantly engaged α3β1 integrins to interact with the RGD-modified substrate on the basis of the observed decrease of osteosarcoma cells adhesion in response to anti- α3β1 treatment (Fig. 9D). This was not observed when ανβ3 and α5β3 were blocked (Fig. 9E). For these antibody inhibition studies, cells were preincubated with 5g/mL anti-o^1 (clone JBS5), anti-ανβΐ (clone LM609) and anti-o^3.

Example 12: Integrin engagement inhibits cell conversion.

Using the same setup as in Example 1 1 (tumor cell and PET functionalized with RGD peptides and an exemplary GFR-binding compound), silencing of integrin a 3 and integrin β 1 expression using shRNA was shown to reduce integrin a3 and integrin β1 mRNA levels by 60-70% and 50-60% respectively and integrin a3 and integrin β1 proteins levels by 60-70% after 24h. It was then shown that both integrins a3 and β1 shRNAs modulated osteosarcoma adhesion and spreading on RGD-modified substrates (Fig. 10 A, B).

Without being bound to any specific theory, integrin α3β1 thus appears to be an important factor in the conservation of osteosarcomas tumourous profile and appears to play an important role in the recoding of osteosarcomas into osteocytes. Herein, α3β1 integrin engagement appears to be involved in the inhibition of osteocytic recoding but not in osteosarcoma induction. Indeed, it was observed, within the framework of this experiment, that spheroid-like structures of osteosarcomas became progressively predominant (Fig. 10C). These results seems to demonstrate that integrin engagement has the ability to influence the behavior of human osteosarcoma towards spheroid-like structures or towards osteocytes.
