A pharmaceutically active substance

The present invention relates to a pharmaceutically active substance, a drug and a pharmaceutical composition.

Cancer is an abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread). Cancer is not one disease. It is a group of more than 100 different and distinctive diseases. Cancer can involve any tissue of the body and have many different forms in each body area. Most cancers are named for the type of cell or organ in which they start. If a cancer spreads (metastasizes), the new tumor bears the same name as the original (primary) tumor.

Typically, cancer can be treated by different options, including chemotherapy, radiation and surgery. Chemotherapy is usually achieved by one or more cytotoxic anti-neoplastic drugs. Traditional cytotoxic agents kill cells that divide rapidly.

However, these cytotoxic agents have toxic side effects and their effectiveness is often limited.

The classical chemotherapeutic drugs are cytotoxic and/or prevent cell division which primarily should address tumor cells, presumably while they are proliferating. There are, however, also normal non-tumor cells which proliferate, such as cells of epithelial or mesenchymal origin which reconstitute damaged or aged tissue and anti cancer drugs could prevent these processes of homeostasis.

A second group of cells which may be stimulated to cell division (proliferation) are immune cells, of the myeloid type or of the lymphocyte type. Immune cells help to fight infections or various origin, microbial, such as bacteria or fungi; or viruses, which may appear due to a new infection or be reactivated, such as viruses of the Herpes virus family. Immune cells may fulfill the task of immune suppression when an infection is under control, or prevent auto-immune reactions or auto-inflammation.

Consequently, these cytotoxic agents have toxic side effects on different cells being very important for the quality of live for human beings having cancer.

In addition thereto, different attempts have been started to treat cancer by providing peptides having an effect on cancer cells. These peptides may introduce apoptosis in cancer cells. E.g. F. Zhong et al. suggest treating lymphocytic leukemia cells by peptide-mediated disruption of Bcl-2-IP3 receptor interaction (F. Zhong et al. ,

BLOOD, 10 MARCH 2011 - VOLUME 117, NUMBER 10; 10.1182/blood-2010-09- 307405.). Aline N. Rabaca et al. describe that AC-1001 H3 CDR peptide induces apoptosis and signs of autophagy in vitro and exhibits antimetastatic activity in a syngeneic melanoma model (Aline N. Rabaca et al., FEBS Open Bio 6 (2016) 885- 901 ; doi:10.1002/2211 -5463.12080). A. D. Woldetsadik et al. disclose that

Hexokinase ll-derived cell-penetrating peptide targets mitochondria and triggers apoptosis in cancer cells (A. D. Woldetsadik et al., FASEB J. 31 , May (2017); doi:

10.1096/fj.201601173R). Xin Deng et al. suggest peptides with anti-cancer activities. Especially Xin Deng et al. state that B1 and its analogs are capable of penetrating into cytoplasm and triggering cytochrome C release from mitochondria, which ultimately resulted in apoptosis (Xin Deng et al., European Journal of Medicinal Chemistry 89 (2015) 540e548; http://dx.doi.Org/10.1016/j.ejmech.2014.10.072). H. Bumpers et al. suggest that Nef-M1 , a CXCR4 peptide antagonist, enhances apoptosis and inhibits primary tumor growth and metastasis in breast cancer (H. Bumpers et al., J Cancer Ther. 2013 June; 4(4): 898-906;

doi: 10.4236/jct.2013.44101 ). Furthermore, WO 03/054009 provides peptides having apoptotic or anti-apoptotic effects to cells.

The proposals mentioned above have not been applied yet. Nevertheless, targeted therapy is known for the therapy of many cancer types.

For example, a phase I clinical study used cilengitide treatment in a dose escalation study on various brain tumors (NABT 9911 ). In some of the glioblastoma multiforme (GBM) patients in this study, an indication of response was seen. Cilengitide (= cyclo- (Arg-Gly-Asp-DPhe-NMe-Val), in very marked contrast to most cancer therapeutics currently in use has a very innocuous side effect profile, with no known maximally tolerated dose (MTD) issues in humans - and is very well tolerated.

In addition to the essentially 100% mortality in GBM patients (2-year survival rate about 25%), the morbidity from neurological complications also rapidly degrades the quality of life (QOL).

For example, the standard of treatment of glioblastoma multiforme, associating radiotherapy and temozolomide, has only increased the median survival of resected patients by 2.5 months (from 12.1 to 14.6 months) compared to radiotherapy alone (Stupp et al. , 2005). However, in combination with cyclo-(Arg-Gly-Asp-DPhe-NMe- Val), this standard treatment shows significantly improved efficacy with respect to an increased median survival and quality of life.

The annual worldwide incidence of squamous cell cancer of the head and neck (or Squamous Cell Carcinoma of the Head and Neck), both also referred to as SCCHN, is estimated at 500,000 patients; in the United States and Europe, 118.000 new patients are diagnosed annually. SCCHN is more predominant in males with a male:female ratio of 2: 1 -4:1. There is a positive relationship between smoking habits, alcohol consumption, and head and neck cancer. Approximately 90% of all head and neck malignancies are of squamous cell histology (SCCHN). Most patients are diagnosed with SCCHN at an age of 50-70 years.

A majority of patients (75%) have locally advanced disease at diagnosis. Those patients are mainly treated with radiotherapy and in some cases surgery. Newer strategies such as induction chemotherapy or chemoradiotherapy could provide better survival; however, the 5-year survival rate remains around 30%, and 60% of subjects will experience a loco-regional or distant relapse within 2 years of initial treatment.

The group of subjects with recurrent disease and/or with newly diagnosed distant metastases has very heterogeneous disease characteristics. Their median survival time, however, remains around 6-8 months with a poor quality of life. This dismal prognosis has not changed in the past 30 years.

Lung cancer is the leading cause of cancer deaths worldwide. About 170,000 new cases of lung cancer and 160,000 deaths due to this disease per year occur in the United States alone. Non-small cell carcinoma (NSCLC) accounts for approximately 80% of all lung cancers.

At the time of diagnosis, approximately 30% of NSCLC patients present with locally advanced and 40% with metastatic disease. Surgical results in earlier stages are poor compared to other tumor types (about 40% of recurrence in stages l-ll). In metastatic disease, chemotherapy is the treatment of choice, but survival benefits have been modest, resulting in one-year survival of 40%, and five-year survival of less than 15%. It is commonly accepted that the standard treatment for advanced disease (stage IV and lllb with malignant pleural effusion) consists of platin-based (cisplatin or carboplatin) chemotherapy. However, there are many open questions in the management of these patients, such as the role of combination therapy regimen including more than two drugs, non-platinum-based therapies, and new targeted therapeutical approaches.

Currently, response rates of about 20%-30% and median survival times of 6 to 11 months have been observed in the treatment of metastatic NSCLC. Several chemotherapy combinations are used with comparable efficacy. Accordingly, also in this field is a high unmet medical need for improved methods of treatment.

Small cell lung cancer (SCLC) accounts for 15-20% of all lung cancer cases in the world, equating to approximately 80,000 new patients every year. A recent analysis of the Surveillance, Epidemiology and End Results database confirmed that in the United States, the proportion of small cell lung cancer patients has decreased from about 20% to 13.8% in 1998, likely due to the implementation of smoking cessation programs. This success, however, is to some extent outweighed by the high and rising prevalence of tobacco smoking in other parts of the world.

SCLC is typically disseminated at the time of presentation, with approximately 60% to 70% of patients having disseminated (extensive-stage) disease at presentation.

Thus, surgery is rarely an option, and applies only to patients with localized (limited) disease. Relapse and death from SCLC is imminent even in patients who are treated with surgical resection. Without other therapy than surgery, survival was 2 months for patients with extensive-stage SCLC and 3 months for patients with limited-stage SCLC (Green, Am J Med 1969).

Systemic combination chemotherapy remains the mainstay of SCLC treatment, both in limited and extensive stage of their disease. For more than 20 years, etoposide and cis-/carboplatin are considered the current standard agents used in combination for the first-line treatment of patients with SCLC in the Western world. Combination therapy with more than two drugs in clinical trials has resulted in higher response rates, but also higher toxicity, and did not result in a clinically relevant overall survival benefit. Time to progression is short, with the majority of patients progressing within 3 months of completing chemotherapy. The median survival is 7 to 11 months. Less than 5% of patients survive longer than 2 years.

The term breast cancer or malignant breast neoplasm is commonly used as the generic name for cancers originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from ducts are often referred to as ductal carcinomas; those originating from lobules are often referred to as lobular carcinomas. However, there are many different types of breast cancer, with different stages (spread), aggressiveness, and genetic makeup; survival varies greatly depending on those factors. Breast cancer is about 100 times more common in women than in men, although males tend to have poorer outcomes due to delays in diagnosis.

Breast cancer (BRCA) is the most common cancer in women worldwide, accounting for ~ 30% of all female cancers. It represents a major public health problem mainly due to its high incidence, excess mortality and therapeutic challenges. More than 1.1 million women are diagnosed with BRCA each year worldwide, and more than 400.000 succumb to this disease. Approximately 75% of all newly diagnosed patients are women with early stage BRCA.

Generally, treatment options include surgery, drug based therapy, including but not limited to hormonal therapy and/or chemotherapy, and radiation. Some breast cancers require hormones to grow, such as estrogen and/or progesterone, and have receptors for those hormones. After surgery those cancers are treated with drugs that interfere with those hormones and/or shut off the production of said hormones in the ovaries or elsewhere. Such drugs are generally referred to as hormone antagonists or hormone blockers.

However, despite surgery and the use of adjuvant treatments such as chemotherapy, hormonal therapy, radiotherapy and targeted drugs, many of these patients will die as a result of local or distant recurrence. The 5-year survival rate for metastatic breast cancer is in the range of 25%.

As can be seen from the above, management of cancer has been difficult and it still is difficult. Thus, even in view of the results achieved within the last years, the prognosis of the patients regarding most cancerous diseases is still very grim. There still exists a growing need in the art in order to develop new pharmaceuticals, including new compounds and advantageous formulations of non-compounds for treating cancer and/or metastases thereof. Preferably, said new pharmaceuticals should allow for convenient and/or efficacious systemic application or administration. Thus, there is a need for improved drugs, medicaments, therapy methods and treatment regimen.

An object of the present invention therefore was to provide a new compound, preferably a new and advantageous drug and/or a new and advantageous

pharmaceutical composition. It should preferably be applicable to systemic treatment, preferably lower the dose and/or preferably increase the efficiency of the

pharmaceutical to be applied and/or allow for a more convenient administration and/or dosing regimen.

Thus, there is a high medical need to provide a more effective, better tolerated method for the treatment of subjects, preferably mammalian subjects, more preferably human subjects humans and especially human cancer patients that may be suffering from various cancers and/or metastasis thereof, thus preferably also leading to enhanced progression-free survival (PFS), improved quality of life (QOL) and/or increased median survival.

These objects and further objects which are not stated explicitly but which are immediately derivable or discernible from the connections discussed herein by way of introduction are solved by a pharmaceutically active substance having all features of claim 1.

The present invention accordingly provides a pharmaceutically active substance comprising at least one peptide portion having the amino acid sequences m-v-v-y-f-r (first peptide portion), characterized in that the pharmaceutically active substance comprises at least additional one amino acid and/or peptide portion at the N-terminal end and/or at the C-terminal end of the first peptide portion (second peptide portion and/or third peptide portion) being directly bound to the peptide portion having the amino acid sequences m-v-v-y-f-r (first peptide portion). The expression“being directly bound” is well known in the art and specifies that at the N- terminal end and/or C-terminal end a bond is formed connecting the N- terminal end and/or C- terminal end with an amino acid and/or peptide portion.

It is thus possible in an unforeseeable manner to improve the methods for the treatment of cancer as mentioned above. The present invention accordingly provides a pharmaceutically active substance, preferably an apoptotically active substance, preferably a drug, more preferably a pharmaceutical composition leading to enhanced progression-free survival (PFS), improved quality of life (QOL) and/or increased median survival. Surprisingly, the pharmaceutically active substance, preferably the apoptotically active substance, preferably the drug, more preferably the pharmaceutical composition is well-tolerated and has low side effects.

Moreover, certain immune cells such as T cells (T lymphocytes, CD4 ⁺ or CD8 ⁺ ), and natural killer (NK) cells may be activated to directly attack tumor cells or to support the fight against the tumor. In addition, other cell types such as dendritic cells, monocytes, macrophages and NKT cells may help in the process of tumor attack. The present invention provides a treatment wherein the therapy facilitates the natural recognition and attack of tumor cells by the immune system. Therefore, the immune system is not suppressed by the present pharmaceutically active substances, preferably the apoptotically active substances, preferably drugs, more preferably pharmaceutical compositions but have synergistic effect using the immune systems of persons in need.

Furthermore, as shown in the Examples the pharmaceutically active substances, preferably the apoptotically active substances, preferably drugs, more preferably pharmaceutical compositions of the present invention have a high effectivity with regard to very different cancer cell types. That is, the pharmaceutically active substances, preferably apoptotically active substances, preferably drugs, more preferably pharmaceutical compositions can be successfully applied in order to treat very different cancers. Based on the pathway of action, the cancer cells having a high resistance against conventional chemotherapeutics can be effectively treated using the pharmaceutically active substances, preferably apoptotically active substances, preferably drugs, more preferably pharmaceutical compositions of the present invention.

On the other hand, as shown in the Examples the pharmaceutically active

substances, preferably apoptotically active substances, preferably drugs, more preferably pharmaceutical compositions show a high selectivity and, hence, have low side effects against healthy cells.

The present invention provides therapies which show partial or complete specificity for (direct or indirect) eradication of cancer cells, without attacking normal cells including immune cells, and irrespective of whether the normal cells are in a proliferating or resting (non-dividing) state.

The present invention provides pharmaceutically active substances, preferably apoptotically active substances exhibiting a very high efficiency and a very rapid effect, preferably as pharmaceutical against cancer. Although the pharmaceutically active substances comprises peptides which may have a relatively low half-value time and may be depleted at relatively high speed, the very rapid effect of the pharmaceutically active substances overcompensate these issues. The very rapid effect of the pharmaceutically active substances, preferably apoptotically active substances is very astonishing and is never achieved by any other drug for treatment of cancer. This surprising efficiency regarding the astonishing fastness of the killing of cancer cells improves the survival rates of persons in need.

A combination of such desirable features are not achieved using conventional methods as described above.

The pharmaceutically active substances, preferably apoptotically active substances can be obtained very inexpensively.

The present invention provides pharmaceutically active substances.

Pharmaceutically active substances are considered as substances being useful for the production of pharmaceuticals and include especially active ingredients. Without being limited thereto, it is believed that pharmaceutically active substances are able to induce apoptosis. Apoptosis is well known in the art. Apoptosis is the genetically encoded suicide program, which is induced in eukaryotic cells under certain physiological or pathological conditions. For the purposes of the present invention, "apoptotically active" is understood to mean that the addition of the corresponding substance to the test system shown in present Examples generates a positive or negative effect to the survival of the cells. Preferably, the present substances induce apoptosis and provide a high level of apoptosis (cell death based on suicide program) with regard to cells being prone to apoptosis such as cancer cells while healthy cells are not or only at a low level affected by the substances of the present invention. The apoptosis can be measured by conventional methods being well known in the art such as microscopy and the methods mentioned in the Examples. Although microscopic methods provide most reliable results, for the purpose of the present invention more convenient methods can be applied.

For achieving a high reliability and preciseness, the apoptosis can be measured by microscopy. For achieving reliable results a high number of cells should be used to determine the apoptosis rate as mentioned above and below. Preferably, at least 1000 cell, more preferably at least 10000 cells and even more preferably at least 1000000 cells are used to determine the apoptosis rate. The cells being analysed by conventional microscopy and preferably automatic picture analyses can be

performed. The cells, preferably the cell nucleus being stained by a conventional dye. Cells, especially cell nucleus having a healthy shape (round or spherical shape) and cells, especially cell nucleus having a apoptotic shape (necking, narrowing or any other shape indicating apoptosis as known in the art) are counted. Cells having a necrotic or other non-apoptotic or non-healthy cell shape are considered. Death cells having a non-apoptotic shape, such as necrotic shape can be determined by a staining with propidium iodide. Conventionally, healthy cells and apoptotic cells have a cell wall in good order while necrotic cells have a permeable cell wall.

Consequently, for purpose of the present invention, cells having a permeable cell wall are not considered as healthy cells or apoptotic cells.

Preferably the pharmaceutically active substances, preferably apoptotically active substances inducing apoptosis provide an inducing level of apoptosis of at least 5%, more preferably of at least 10%, even more preferably of at least 30% and even more preferably of at least 40%. The level of apoptosis of apoptosis is preferably measured by microscopy and is determined by the number of the measured apoptotic cells on the basis of the measured total cells.

According to a very preferred embodiment, the level of apoptosis as mentioned above and below refers to an incubation time of about 3 hours.

Preferably, the proportion of cells which has died are preferably determined by two methods, both rely on the analysis of cells by flow cytometry, often called FACS analysis. This technology allows determining the physical and chemical properties of both normal cells and tumor cells. The cells can be labelled by fluorescent dyes, which may bind to cellular DNA or which are coupled to antibodies that bind to proteins or other structures on the cell surface or inside the cells. The cells are suspended and injected into a flow cytometer instrument and, ideally one at a time, the cells flow through a laser beam. The laser light is either scattered or elicits fluorescence at the dyes which were applied and the scattered and the fluorescent light is analyzed by an optical and light detection system. This system with an array of dichroic mirrors or prisms and optical filters serves to direct the light to

photomultipliers that are mounted in defined positions, either in line of the laser and the position where the cell meets the laser beam, thereby delivering signals of the forward-scattered light (FSC); or photomultipliers detect light which is scattered in an angle relative to the FSC beam direction, to detect the side-scattered light (SSC), or to detect selected wave length from fluorescent light. Programmed cell death

(apoptosis) can be detected by changes of the FSC/SSC light scattering pattern, or by the appearance of cells with a low DNA content, as revealed by the so called subG1 peak (Darzynkiewicz et al. , (1992). "Features of apoptotic cells measured by flow cytometry." Cytometry 13(8): 795-808; Vermes et al., (2000) "Flow cytometry of apoptotic cell death." J Immunol Methods 243(1 -2): 167-190).

A first method is based on the cell form measurement, herein called Vital Cells analysis or cell vitality. The basis of this method has been published, e.g. by the documents of Lizard, G. et al. (1995). "Kinetics of plasma membrane and

mitochondrial alterations in cells undergoing apoptosis." Cytometry 21(3): 275-283, doi: 10.1002/cyto.990210308; Taga et al. (2000) "Contribution of automated hematology analysis to the detection of apoptosis in peripheral blood lymphocytes." Cytometry 42(3): 209-214; Vermes et al., (2000) "Flow cytometry of apoptotic cell death." J Immunol Methods 243(1 -2): 167-190.

As disclosed in more detail in the Examples, the analyzation includes a selected cell fraction excluding cells with both small FSC and small SSC values. Therefore, a gating area is drawn in a two-dimensional FSC/SSC plot (region R-1 ) which contains mainly intact cells, but no small vesicles. This is initially done for each cell type using reference cells which were not incubated with substances inducing cell death. The geometry applied for region R-1 is preferably a pentagon, as shown in Figure 1.

Preferably the coordinates for the corner points (ml to m5) are in the following ranges, given as percent of full scale for SSC (S) and FSC (F), respectively:

First point of pentagon ml preferably ranges for SSC (S) from 2.5 % to 25.0 %, more preferably from 5.0 % to 20.0%, more preferably about 15%.

First point of pentagon ml preferably ranges for FSC (F) from 12.0 % to 55.0, more preferably from 15.0 % to 25.0%, more preferably about 20%. F=%).

Second point of pentagon m2 preferably ranges for SSC (S) from 25.0 % to 70.0 %, more preferably from 32.0 % to 45.0%, more preferably about 37%. Second point of pentagon m2 preferably ranges for FSC (F) from 25.0 % to 45.0, more preferably from 30.0 % to 44.0%, more preferably about 36%.

Third point of pentagon m3 preferably ranges for SSC (S) from 30.0 % to 70.0 %, more preferably from 55.0 % to 67.0%, more preferably about 66%.

Third point of pentagon m3 preferably ranges for FSC (F) from 50.0 % to 65.0, more preferably from 52.0 % to 60.0%, more preferably about 56%.

Fourth point of pentagon m4 preferably ranges for SSC (S) from 10.0 % to 60.0 %, more preferably from 13.0 % to 30.0%, more preferably about 21 %.

Fourth point of pentagon m4 preferably ranges for FSC (F) from 42.0 % to 80.0, more preferably from 55.0 % to 75.0%, more preferably about 65%.

Fifth point of pentagon m5 preferably ranges for SSC (S) from 2.0 % to 40.0 %, more preferably from 6.0 % to 20.0%, more preferably about 13%.

Fifth point of pentagon m5 preferably ranges for FSC (F) from 25.0 % to 45.0, more preferably from 30.0 % to 40.0%, more preferably about 35%.

As mentioned above and below, the data for assessing the geometry applied for region R-1 are rough estimations and are preferably optimized as mentioned in the Examples and the documents cited above and below in order to achieve a region R-1 containing mainly intact cells, but no small vesicles. This is initially done for each cell type using reference cells which were not incubated with substances inducing cell death. By this selection of the cell fraction, a bias is prevented which would include a very high number of small cellular vesicles (apoptotic bodies) that are formed by membrane blebbing from dying cells, which have a low DNA content but which, by their large number, would increase the fraction of presumptive subG1 cells.

A second method is based on the analysis of the cell cycle phases which can be drawn from the relative DNA content. Following flow cytometry, the frequency of fluorescence intensities which is proportional to the DNA content is plotted in a single dimension histogram, which reveals whether the cells are either in the Go/G1 phase (resting cells); or the cells proliferate and are in the DNA synthesis (S) phase or in the G2/M phase which is before or at the time of cell division (mitosis). When cells die by apoptosis, cellular changes lead to diminished DNA content resulting in a new peak located before the Go/G1 peak, often called“subG1” peak (Broecker-Preuss et al. (2015) "Cell death induction by the BH3 mimetic GX15-070 in thyroid carcinoma cells." J Exp Clin Cancer Res 34: 69; Darzynkiewicz et al., (1992) "Features of apoptotic cells measured by flow cytometry." Cytometry 13(8): 795-808; Dbaibo et al. (1998) "p53-dependent ceramide response to genotoxic stress." J Clin Invest 102(2): 329-339; Fischbeck et al. (2011 ). "Sphingomyelin induces cathepsin D-mediated apoptosis in intestinal epithelial cells and increases inflammation in DSS colitis." Gut 60(1 ): 55-65). The second method is herein called SubG1 method.

According to a preferred embodiment, the apoptosis level is measured according to the cell cycle SubG1 method being explained in more detail in the Examples and the documents mentioned above published by Darzynkiewicz, Z. et al. (1992). "Features of apoptotic cells measured by flow cytometry." Cytometry 13(8): 795-808, doi:

10.1002/cyto.990130802, where cellular DNA was stained with DAPI; and Broecker- Preuss, M. et al. (2015). "Cell death induction by the BH3 mimetic GX15-070 in thyroid carcinoma cells." J Exp Clin Cancer Res 34: 69, doi: 10.1186/s 13046-015- 0186-x, for staining with propidium iodide (PI); both methods allow to quantify the cell cycle subG1 fraction with increased DNA content typical for apoptotic cells.

SEQ ID No 27) could be substituted by any other amino acid. Preferably the substituted amino acid residue is an amino acid residue having a high similarity. Amino acids having a high similarity are selected from the same group as the amino acid residue being substituted. That is, if the tryptophan is substituted, the amino acid residue substituting the tryptophan is preferably an aromatic amino acid residue such as phenylalanine or tyrosine. Regarding the groups for determining the similarity, in the present invention the groups for determining the similarity are based on the side chain classes, including the amino acid classes“acid”,“aliphatic”,“amide”,

“aromatic”,“basic”,“cyclic”,“hydroxyl-containi ng” and/or“sulfur-containing”. More preferably, a specific D-amino acid is preferably substituted by another D-amino acid. That is, e.g. in the sequence k-k-w-m -v-v-v-f-r-k (e. g. SEQ ID No 27) the underlined lysine is preferably substituted by an arginine residue being in the D form and the tryptophan is preferably substituted by His, Phe, Tyr, if a derivate of the sequence k- k-w-m -v-v-v-f-r-k (e. g. SEQ ID No 27) is applied.

The amino acid class“acid” include the amino acids Asp and Glu. The amino acid class“aliphatic” include the amino acids Ala, Gly, lie, Leu and Val. The amino acid class“amide” include the amino acids Asn and Gin. The amino acid class“aromatic” include the amino acids His, Phe, Trp and Tyr.

The amino acid class“hydroxyl-containing” include the amino acids Ser and Thr. The amino acid class“sulfur -containing” include the amino acids Cys and Met.

According to a preferred embodiment the apoptotically active substance preferably comprises a peptide chain being formed by the first peptide portion and the second and/or third peptide portion and the peptide chain has a chain length of < 100 amino acids, more preferably the apoptotically active substance comprises a peptide chain being formed by the first peptide portion and the second and/or third peptide portion and the peptide chain has a chain length of < 50 amino acids. For the purposes of the present invention, the term "peptide" is understood to mean a substance that comprises a chain of 2 or more amino acids linked by peptide bonds.

Peptides for use in the pharmaceutically active substance according to the invention preferably comprise 7 to 100 amino acids, more preferably 8 to 50 and especially 9 to 40 amino acids.

Preferably, the apoptotically active substance is a peptide that has a chain length of < 100, preferably < 50 amino acids.

For the purposes of the present invention, the term "protein" is understood to mean a substance in which multiple "peptides" are linked to each other, for example by molecular bonds such as disulphide bonds or by salt bridges. This definition equally encompasses native proteins as well as at least partially "artificial" proteins, wherein such "artificial" proteins may be modified, for example by attaching chemical groups to the amino acid chain that normally do not occur in native proteins.

Native peptides, however, often have a low metabolic stability with respect to peptidases and relatively poor bioavailability.

Proceeding from the above-described peptides, a person skilled in the art, without exercising inventive skill, will be able to develop a whole number of derived compounds that have a similar or identical mode of action and, among other things, are also referred to as peptide mimetics. For the purposes of the present invention, peptide mimetics refer to compounds that mimic the structure of peptides and, serving as ligands, are able to imitate (agonist) or block (antagonist) the biological activity at the receptor/enzyme level. Above all, the peptide mimetics are to have improved bioavailability and improved metabolic stability. The manner of mimetization can range from a slightly modified original structure to a pure non-peptide, see, for example, A. Adang et al., Reel. Tray. Chim. Pays-Bas 113 (1994), 63-78.

In principle, the following mimetization/derivatization options of a peptide structure are available:

• use of D- instead of L-amino acids

• modification of the side chain of amino acids

• alteration/extension of the peptide main chain

• cyclization for conformational stabilization

• use of templates that forcibly create a certain secondary structure

• use of a non-peptide backbone, which together with suitable groups/side

chains mimics the structure of the peptide

While it is possible to enhance the proteolytic stability of a peptide by exchanging L- with D-amino acids, or by exchanging D- with L-amino acids, modifying the side chains of one of the amino acids often improves the binding properties of the entire peptide.

An alteration of the peptide backbone generally involves exchanging an amide group with amide-like groups (J. Gante, Angew. Chem. 106 (1994), 1780-1802). This measure allows both the binding affinity and the metabolic stability of the native peptide to be influenced.

Cyclization of a linear peptide establishes the flexibility of the same, and hence the global conformation. When the biologically active conformation is fixed, the affinity of the peptide for the receptor is increased since the decrease in entropy in the bond is less than in the case of the bond of a flexible, linear peptide. For this purpose, amino acid side chains not involved in receptor identification are linked to each other or to the peptide scaffold. The secondary structure of the peptide plays a crucial role for the molecular identification of the receptor. In addition to a-helix and b-sheet, what are known as turns form important conformation elements in the peptide chain. Replacing these structural units with a building block that, after insertion into a peptide, stabilizes a defined secondary structure, resulted in the concept of secondary structure mimetics.

The water solubility of the peptides can also be increased, for example by introducing S- and C-glycopeptide derivatives. Further measures can be the PEGylation of the peptides, for example.

It can be provided that the apoptotically active substance comprises a peptide chain being formed by the first peptide portion and the second and/or third peptide portion and the peptide chain preferably has a solubility in water of at least 2 g/l, preferably at least 4 g/l.

It can be provided that the peptide chain being formed by the first peptide portion and the second and/or third peptide portion and the peptide chain preferably has a solubility in water of at least 2 g/l, preferably at least 4 g/l.

For some applications and/or formulation the apoptotically active substance comprises a peptide chain being formed by the first peptide portion and the second and/or third peptide portion comprises a portion providing improved hydrophobicity. Such portion providing improved hydrophobicity is especially useful for forming a complex or other adduct with some proteins being able to carry the apoptotically active substance of the present invention to the cancer cells being prone to apoptosis and to improve the life time of the apoptotically active substance within the body of subjects, preferably mammalian subjects, more preferably human subjects humans and especially human cancer patients.

Preferably, the portion providing improved hydrophobicity is a fatty acid residue and/or an alkyl residue having about 5 to 40 C-atoms, more preferably about 10 to 30 C-atoms, even more preferably about 12 to 24 C-atoms. The fatty acid residue and/or an alkyl residue can be saturated or unsaturated and linear or branched. Preferred fatty acid residues are e.g. hexanoate, heptanoate, octanoate, nonanoate,

decanoate, undecanoate, dodecanoate, tridecanoate, tetradecanoate,

pentadecanoate, hexadecanoate, heptadecanoate, octadecanoate, nonadecanoate, icosanoate, myristate, laurate, palmitate, stearate, and/or oleate. Preferred alkyl residues are e.g. hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl (lauryl), tridecyl, tetradecyl (myristyl), pentadecyl, hexadecyl (palmityl, cetyl), heptadecyl, octadecyl (stearyl), nonadecyl, icosyl (arachidinyl), docosyl (behenyl). The portion providing improved hydrophobicity can be linked by any linker being known in prior art.

Preferably, the fatty acid can be linked by a peptide bond to the N-terminal amino acid of the inventive peptide.

[Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart), in particular under reaction conditions which are known and appropriate for the said reactions. In this context, use can also be made of known variants which are not mentioned in any greater detail here.

It is therefore obvious that a person skilled in the art, proceeding from the knowledge imparted by the present invention, will easily arrive at a whole number of derived peptide mimetics, which, however, are all covered by the present invention.

The apoptotically active substance inducing apoptosis, preferably the peptides mentioned above may be used as a salt.

A base of a peptide can be converted into the associated acid addition salt using an acid. Suitable acids for this reaction are, in particular, those which yield

physiologically acceptable salts. Thus inorganic acids can be used, examples being sulfuric acid, nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acid such as orthophosphoric acid, sulfamic acid, and also organic acids, especially aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or polybasic carboxylic, sulfonic or sulfuric acids, for example formic acid, acetic acid, propionic acid, pivalic acid, diethyl-acetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, benzoic acid, salicylic acid, 2- or 3-phenylpropionic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methane- or ethanesulfonic acid, ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalene-mono- and -disulfonic acids, laurylsulfuric acid. Salts with physiologically unacceptable acids, for example picrates, can be used for isolating and/or purifying the pharmaceutically active substance according to the present invention.

Alternatively, an acid of a peptide can be converted into one of its physiologically acceptable metal or ammonium salts by reaction with a base. Particularly suitable salts in this context are the sodium, potassium, magnesium, calcium and ammonium salts, and also substituted ammonium salts, for example the dimethyl-, diethyl- or diisopropylammonium salts, monoethanol-, diethanol- or triethanolammonium salts, cyclohexylammonium salts, dicyclohexylammonium salts, dibenzylethylene diammonium salts, and also, for example, salts with N-methyl-D-glucamine or with arginine or lysine.

In specific embodiments, these systems preferably comprise a polymer-linker-drug conjugate and a recognition segment. The recognition segment is preferably an oligopeptide and/or an oligosaccharide. Preferably, the polymer is a polymeric carrier, more preferably the polymeric carrier is hydrophilic, biocompatible and biodegradable. Preferably, the polymeric carrier is larger than the renal excretion limit. Biocompatible polymers are not significantly toxic to cells. In order to prevent chromic accumulation of polymeric carriers that are larger than the renal excretion limit are preferably both biocompatible and biodegradable. Biodegradable polymers are preferably broken down by the cellular machinery and/or by hydrolysis into components that the cells can either reuse or dispose of without significant toxic effect. In preferred embodiments, a biodegradable polymer and its biodegradation by products are biocompatible. It is to be understood that any known biodegradable polymer may be incorporated in a conjugate. Preferred polymeric carriers are hydrophilic, e.g., they may include polar groups, such as hydroxyl or amine groups; anionic groups, such as carboxylate, sulfonate, sulphate, phosphate, or nitrate groups; or cationic groups, such as protonated amine, quaternary ammonium, or phosphonium groups. Suitable hydrolytically degradable polymers known in the art include for example, certain polyesters, polyanhydrides, polyorthoesters,

polyphosphazenes and polyphosphoesters. Other biodegradable polymers known in the art, include, for example, certain carbohydrates, polyhydroxyacids,

polypropylfumerates, polycaprolactones, polyamides, poly(amino acids), polyacetals, polyethers, biodegradable polycyanoacrylates and biodegradable polyurethanes. For example, specific biodegradable polymers that may be used in the present invention include but are not limited to alginate, carboxymethyl-alginate, cellulose, polylysine, poly(lactic acid), poly(glycolic acid), poly(caprolactone), poly(lactide-co-glycolide), poly(lactide-co-caprolactone) and poly(glycolide-co-caprolactone). Those skilled in the art will recognize that this is an exemplary, not comprehensive, list of

biodegradable polymers. It is further to be understood that inventive conjugates may comprise block co-polymers, graft co-polymers, or adducts of these and other polymers. Preferably, the conjugates include a linker with at least a first and a second end. The linker preferably includes at least one segment that is cleaved when exposed to a digestive enzyme that is expressed in the target tissue. Preferably the digestive enzyme is overexpressed in the target tissue. In preferred embodiments the cleavable segment includes an oligopeptide or an oligosaccharide sequence. The first end of the linker is preferably associated with the polymeric carrier and the second end is preferably associated with the drug molecule. When two entities are "associated with" one another as described herein, they are linked by a covalent or ligand/receptor type interaction. Preferably, the association is covalent. One of ordinary skill in the art will appreciate that a whole host of synthetic methods exist for covalently linking oligopeptide or oligosaccharide segments with the polymeric carriers and drugs of the present invention.

The chemical composition of the cleavable segment (e.g., the length and sequence of amino acids or sugars) will depend for the most part on the motif that is recognized and cleaved by the digestive enzyme in the target tissue. The cleavage motifs are known for a number of proteases. For example, the table provided in Appendix A of document WO 2013/033717 A1 lists the cleavage motifs for a range of secreted or membrane bound proteases that are overexpressed in certain tumor tissues. These are all potential target enzymes that could be used to trigger release of drug molecules from inventive conjugates. The Examples describe the optimization of a cleavage segment that is recognized by matrix-metalloproteinase II (MMP-2), a proteinase that is also overexpressed in a variety of tumors.

A variety of methods are also known in the art that can be used to determine the cleavage motif of a target enzyme when it is not yet known. These include substrate phage display libraries (Matthews and Wells, Science 260:1113, 1993); positional- scanning peptide libraries (Rano et al. , Chem. Biol. 4:149, 1996); and mixture-based peptide libraries (Turk et al., Nature Biotechnology 19:661 , 2001 ). Positional- scanning synthetic peptide libraries are based on the detection of cleavage by the release of a C-terminal fluorogenic group. The technique is rapid and enables analysis of all possible peptide sequences. Currently the libraries only provide sequence specificity N-terminal to the cleavage site and cannot be used with proteases that require amino acid residues C-terminal to the cleavage site; this restricts their use largely to serine and cysteine proteases. Mixture-based peptide libraries offer an alternative that can provide both general applicability and speed.

The cleavage site motif C-terminal to the cleavage site is first determined by partial digestion and N-terminal sequencing of a completely random peptide mixture.

Information from this first round of screening is then used to design a second library in which strong selected amino acids are fixed, allowing data on sites N-terminal to the cleavage site to be obtained. Reiteration of this process allows an optimal recognition sequence to be determined. The method has recently been used to determine the cleavage motifs of a variety of matrix-metalloproteinases (Turk et al. , Nature Biotechnology 19:661 , 2001 ). The phage display method has been used to determine peptide substrates for a number of proteases, for example, plasmin (Hervio et al., Chemistry & Biology 7:443, 2000); tissue-type plasminogen activator (Ding et al., Proc. Natl. Acad. Sci USA 92: 7627, 1995; Ke et al., J. Biol. Chem.

272:16603, 1997); prostate-specific antigen (Coombs et al., Chemistry & Biology 5:475, 1998); and membrane type-1 matrix metalloproteinase (Ohkubo et al., Biochem. Biophys. Res. Commun. 266:308, 1999).

Preferably, sequences which are labile to target enzyme but resistant to serum proteins can be preferentially selected from a library of peptides. For example, in a first screen, phage that are released upon incubation with the target enzyme are enriched. These phage are then incubated with serum proteins. Phage which remain on the affinity support are then enriched. The DNA sequence of the phagemids can be determined and translated into an amino-acid sequence.

A system comprising a polymer-linker-drug conjugate and a recognition segment of this type is described and depicted in Reference US 2004/116348. Reference US 2004/116348 is hereby incorporated by reference. The peptides being disclosed as pharmaceutical active as mentioned in US 2004/116348 must be replaced by one or more pharmaceutically active substances, preferably apoptotically active substances inducing apoptosis of the present invention

In a further embodiment, particles encapsulating one or more pharmaceutically active substances, preferably apoptotically active substances inducing apoptosis of the present invention are preferably used for the applying the present drugs to a subject in need as mentioned above and below.

Preferably, the particles encapsulating one or more apoptotically pharmaceutically active substances, preferably apoptotically active substances inducing apoptosis of the present invention are preferably nanocapsules that can be tuned to release agents such as polypeptides into selected environments.

Preferably, polymeric nanocapsule are disposed around one or more polypeptides, wherein the nanocapsule is designed to degrade in certain environments thereby releasing the polypeptides. Preferably these methods include forming a mixture comprising a polypeptide, a plurality of polymerizable monomers; and a crosslinking agent that includes a plurality of amino acids linked by peptide bonds in a sequence or "motif that is recognized and cleaved by a protease. In certain embodiments of this aspect of the invention, the nanocapsule is designed for use with proteases that recognize amino acid sequences that are at least 5 amino acids in length such as KRVK (SEQ ID NO: 101 ), GGIPVSLRSGGK (SEQ ID NO: 102) or GGVPLSLYSGGK (SEQ ID NO: 103). In certain embodiments of this aspect of the invention, polymeric nanocapsules used in these methods are disposed within a matrix comprising a hydrogel. Optionally, the polymeric nanocapsules are covalently coupled to the hydrogel (e.g. via a crosslinking agent disclosed herein).

In methods to obtain these embodiments according to this aspect of the invention, the nanocapsule forming mixture is exposed to conditions that first allow the plurality of polymerizable monomers and the crosslinking agent to adsorb to surfaces of the polypeptide. Polymerization of the plurality of polymerizable monomers and the crosslinking agent at interfaces between the monomers and the polypeptide is then initiated so that a modifiable polymeric nanocapsule is formed, one that surrounds and protects the polypeptide. Typically, polymerization is initiated by adding a free radical initiator to the mixture and the resultant polymer chains are then linked together via one or more crosslinking agents. In illustrative embodiments, the crosslinking agent comprises a sequence of amino acids that are linked by peptide bonds, wherein the sequence comprises an amino acid motif that is recognized and cleaved by one or more proteases. In typical embodiments according to this aspect of the invention, the polypeptide is not covalently coupled to the polymeric nanocapsule following the polymerization of the plurality of polymerizable monomers and the crosslinking agent, and is free to migrate away from the nanocapsule upon loss of its integrity (e.g. as a result of cleavage of its peptide bonds). Optionally, the mixture comprises a plurality of polypeptides associated within a protein complex (e.g. a multimeric protein complex). In certain embodiments of the invention, polymeric nanocapsules used in these methods are formed within a matrix comprising a hydrogel (e.g. by controlling polymerization conditions).

Illustrative embodiments include methods of controlling the release of a polypeptide cargo from a polymeric nanocapsule into a selected environment (e.g. control the rate at which polypeptide is released and/or control/select the specific environment in which polypeptide is released). In these methods, enzyme-responsive protein nanocapsules are synthesized that can release protein cargoes in response to specific enzymes (e.g. proteases secreted during certain cellular events) with a high degree of specificity as well as a controlled rate of release (e.g. by controlling reaction condition so as to tune the material profiles of the nanocapsule

compositions). Typically these polymeric nanocapsules are formed from a mixture comprising the polypeptide, polymerizable monomers, an initiator that reacts with the polymerizable monomers so as to generate polymers, wherein the polymers form the polymeric nanocapsule, a first crosslinking agent that links the polymers, wherein the first crosslinking agent is selected to comprise a peptide having an amino acid sequence that is cleaved by a protease, and a second crosslinking agent that links the polymers, wherein the second crosslinking agent does not comprise a peptide having an amino acid sequence that is cleaved by the protease. In certain

embodiments of the invention, polymeric nanocapsules are disposed within a three dimensional matrix comprising a hydrogel.

In typical methods, the nanocapsule is designed so that protease mediated cleavage of the peptide in the first crosslinking agent degrades the polymeric nanocapsule so as to release the polypeptide from the polymeric nanocapsule and allow it to migrate in to the external environment. In these methods, the relative amounts of the first crosslinking agent and the second crosslinking agent in the mixture can be selected to control release of the polypeptide from the polymeric nanocapsule. Further methodological steps in this embodiment of the invention comprise placing the polymeric nanocapsules in an environment selected to include a protease that cleaves the amino acid sequence of the peptide, and then allowing the protease in the selected environment to cleave the amino acid sequence of the peptide, thereby releasing the polypeptide from the polymeric nanocapsule into the selected environment. In certain embodiments of the invention, the protease is produced by a human cell within the selected environment (e.g. an in vivo environment).

Another embodiment of the invention is a method of forming a polymeric

nanocapsule around a polypeptide, wherein the polymeric nanocapsule is designed to release the polypeptide into a selected environment. These methods comprise forming a mixture that includes the polypeptide of interest (preferably a

pharmaceutically active substance according to the present invention), a plurality of polymerizable monomers, a first crosslinking agent comprising a peptide having an amino acid sequence that is cleaved by a protease and a second crosslinking agent does not comprise a peptide having an amino acid sequence that is cleaved by the protease. These methods further comprise allowing the plurality of polymerizable monomers and the crosslinking agents to adsorb to surfaces of the polypeptide and then initiating polymerization of the plurality of polymerizable monomers and the first and second crosslinking agents at interfaces between the monomers and the polypeptide. In this way, proteolytically degradable polymeric nanocapsules are formed around one or more polypeptides. In certain embodiments of the invention, the polymeric nanocapsule is formed from a mixture further comprising a third crosslinking agent that links a first polymer with a second polymer, wherein the third crosslinking agent comprises a peptide having an amino acid sequence that is cleaved by a protease. As discussed herein, embodiments of the invention can be adapted for use with a wide variety of proteases. In illustrative embodiments of the invention, amino acid sequence that is cleaved by the protease comprises a sequence cleaved by plasmin such as KRVK (SEQ ID NO: 101 ), or a sequence cleaved by matrix metalloproteinase such as GGIPVSLRSGGK (SEQ ID NO: 102) or GGVPLSLYSGGK (SEQ ID NO: 103).

Yet another embodiment is a composition of matter comprising a constellation of elements that are arranged in the composition to form proteolytically degradable polymeric nanocapsules. Typically these compositions include at least one

polypeptide and a polymeric network, wherein polymers in the polymeric network are coupled together by a first crosslinking agent and a second crosslinking agent so as to form a shell that encapsulates the polypeptide. Optionally in these embodiments, the shell that encapsulates the polypeptide has a diameter between 15 and 35 nanometers. Preferably, the first crosslinking agent comprises a peptide having an amino acid sequence that is cleaved by a protease, and the second crosslinking agent does not comprise a peptide having an amino acid sequence that is cleaved by the protease. In such compositions, the polymers, the first crosslinking agent and the second crosslinking agent are disposed within the polymeric network in an orientation so that proteolytic cleavage of the first crosslinking agent releases the polypeptide from the shell into an external environment. A wide variety of polypeptides can form the cargo of the polymeric nanocapsules disclosed herein. Preferably, the

polypeptide is an apoptotically active substance inducing apoptosis

A system comprising a particle encapsulating peptides of this type is described and depicted in Reference WO 2013/033717 A1. Reference WO 2013/033717 A1 is hereby incorporated by reference. The peptides being disclosed as pharmaceutical active as mentioned in WO 2013/033717 A1 must be replaced by one or more pharmaceutically active substances, preferably apoptotically active substances inducing apoptosis of the present invention.

A preferred subject of the instant invention is the use of apoptotically active substance inducing apoptosis, the pharmaceutically acceptable derivatives, solvates and/or salts thereof, for the manufacture of a composition as described herein and/or the paragraphs relating thereto that is administered to a subject in a method for treating disorders, preferably disorders as described herein and and/or the

paragraphs relating thereto.

An especially preferred subject of the instant invention is the use of the apoptotically active substance inducing apoptosis, the pharmaceutically acceptable derivatives, solvates and/or salts thereof, preferably the preferred embodiments thereof as mentioned above and below, for the manufacture of a composition for the treatment of disorders, wherein the composition is as described herein and/or the paragraphs relating thereto, and preferably wherein disorders to be treated are as described herein and/or the paragraphs relating thereto. Another preferred subject of the invention relates to the use of the composition as described herein, as a pharmaceutical for treating disorders, preferably disorders as described herein.

The term "disorders" is known and understood in the art. Preferably, the disorders to be treated with the composition according to the invention are hyperproliferative disorders, more preferably oncologic disorders and especially cancerous disorders.

Preferably, the disorders to be treated are selected from cancer and metastases thereof.

A further subject matter of the present invention is a use of an apoptotically active substance of the present invention or of a pharmaceutically acceptable salt thereof for preparation of a drug. Preferably the apoptotically active substance of the present invention or of a pharmaceutically acceptable salt thereof is used for preparation of a drug for the treatment of cancer disease. Especially preferred is a method for treating disorders, especially disorder selected from cancer and/or metastases thereof, preferably cancer and/or metastases thereof as described herein.

A further subject matter of the present invention is a drug for the treatment of cancer, comprising at least one apoptotically active substance of the present invention or a pharmaceutically acceptable salt of the apoptotically active substance and a pharmaceutically acceptable carrier.

Preferably, the cancer disease is related to cancer of head, neck, eye, mouth, throat, esophagus, bronchus, larynx, pharynx, chest, bone, lung, colon, rectum, stomach, prostate, urinary bladder, uterine, cervix, breast, ovaries, testicles or other

reproductive organs, skin, thyroid, blood, lymph nodes, kidney, liver, pancreas, brain, central nervous system, solid tumors and blood-borne tumors.

It is to be appreciated that references to "treating" or "treatment" include prophylaxis as well as the alleviation of established symptoms of a condition. "Treating" or "treatment" of a state, disorder or condition therefore includes: (1 ) preventing or delaying the appearance of clinical symptoms of the state, disorder or condition developing in a human that may be afflicted with or predisposed to the state, disorder or condition but does not yet experience or display clinical or subclinical symptoms of the state, disorder or condition, (2) inhibiting the state, disorder or condition, i.e., arresting, reducing or delaying the development of the disease or a relapse thereof (in case of maintenance treatment) or at least one clinical or subclinical symptom thereof, or (3) relieving or attenuating the disease, i.e. , causing regression of the state, disorder or condition or at least one of its clinical or subclinical symptoms.

The drug of the present invention and/or the pharmaceutical composition is preferably used for the treatment of advanced cancer, recurrent cancer, unresectable cancer, metastatic cancer and/or locally advanced cancer.

“Advanced" cancer is one which has spread outside the site or organ of origin, either by local invasion or metastasis. Accordingly, the term "advanced" cancer includes both locally advanced and metastatic disease.

"Recurrent" cancer is one which has regrown, either at the initial site or at a distant site, after a response to initial therapy, such as surgery. A "locally recurrent" cancer is cancer that returns after treatment in the same place as a previously treated cancer.

"Unresectable" cancer is not able to be removed (resected) by surgery.

"Metastatic" cancer refers to cancer which has spread from one part of the body (e.g. the lung) to another part of the body.

"Locally advanced" cancer refers to cancer that has spread to nearby tissues or lymph nodes, but not metastasized. "Advanced unresectable " cancer is one which has spread outside the site or organ of origin, either by local invasion or metastasis and which is not able to be removed (resected) by surgery.

"Subject" includes a human patient. The patient may be a "cancer patient," i.e. one who is suffering or at risk for suffering from one or more symptoms of cancer, in particular non-small cell lung cancer. "Infusion" or "infusing" refers to the introduction of a drug-containing solution into the body through a vein for therapeutic purposes. Generally, this is achieved via an intravenous (IV) bag. "Systemic treatment" is a treatment wherein the drug substance travels through the bloodstream, reaching and affecting cells all over the body.

Preferably, the cancers to be treated are selected from solid tumours and/or metastases thereof. The terms "hyperproliferative disorders", "oncologic disorders", "cancer", "solid tumours" and "metastases" are known and understood in the art.

The terms "cancer" and/or "tumor" preferably refer to or describe the physiological condition in subjects, preferably mammalian subjects and even more preferably humans, that is typically characterized by upregulated or preferably unregulated cell growth, even more preferably benign and/or malignant cell growth and especially malignant cell growth. Especially preferably, the term "cancer" as used herein includes malignant neoplasms or consists of malignant neoplasms.

Typically, the terms "cancer" or“malignant neoplasms” describe a class of diseases in which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, or spreading to other locations in the body via lymph or blood.

The term "metastases” (singular: metastasis) is known and understood in the art.

In the context of the present invention metastasis or metastatic disease (sometimes abbreviated mets), preferably refers to the spread of a cancerous disease from one organ or part to another organ or part, preferably a non-adjacent organ or part. The word metastasis means "displacement" in Greek. The plural is metastases.

According to an established theory, cancer occurs after a single cell in a tissue is progressively genetically damaged to produce a cancer stem cell possessing a malignant phenotype. These cancer stem cells are thought to be able to undergo uncontrolled abnormal mitosis, which would then serve to increase the total number of cancer cells at that location. When the area of cancer cells at the originating site become clinically detectable, it is preferably called primary tumor. Some cancer cells are also thought to acquire the ability to penetrate and infiltrate surrounding normal tissues in the local area, forming a new tumor. The newly formed "daughter" tumor in the adjacent site within the tissue is preferably called a local metastasis.

Some cancer cells are thought to be able to acquire the ability to penetrate the walls of lymphatic and/or blood vessels, after which they would then be able to circulate through the bloodstream (circulating tumor cells) to other sites and tissues in the body. This process is preferably known as lymphatic or hematogeneous spread, respectively. After the tumor cells come to rest at another site, they seem to be able to re penetrate through the vessel or walls, continue to multiply, and eventually another clinically detectable tumor is formed. This new tumor is known as a metastatic (or secondary) tumor. Metastasis is one of three hallmarks of malignancy (contrast benign tumors). Most tumors or malignant neoplasms can metastasize, although in varying degrees.

When tumor cells metastasize, the new tumor is preferably called a secondary or metastatic tumor, and its cells are like those in the original tumor. This means, for example, that, if breast cancer metastasizes to the lungs, the secondary tumor is made up of abnormal breast cells, not of abnormal lung cells. The tumor in the lung is then called metastatic breast cancer, not lung cancer.

Cancer cells may spread to lymph nodes (regional lymph nodes) near the primary tumor. This is called nodal involvement, positive nodes, or regional disease.

("Positive nodes" is a term that would be used by medical specialists to describe a patient's condition, meaning that the patient's lymph nodes near the primary tumor tested positive for malignancy. It is common medical practice to test by biopsy at least two lymph nodes near a tumor site when doing surgery to examine or remove a tumor.) Localized spread to regional lymph nodes near the primary tumor is preferably not counted as metastasis, although this is a sign of worse prognosis. Transport through lymphatics is the most common pathway for the initial

dissemination of cancers or carcinomas.

There is a propensity for certain tumors to seed in particular organs. For example, prostate cancer usually metastasizes to the bones. In a similar manner, colon cancer has a tendency to metastasize to the liver. It is believed that it is difficult for cancer cells to survive outside their region of origin, so in order to metastasize they must find a location with similar characteristics. For example, breast tumor cells, which gather calcium ions from breast milk, metastasize to bone tissue, where they can gather calcium ions from bone. Malignant melanoma spreads to the brain, presumably because neural tissue and melanocytes arise from the same cell line in the embryo.

It is theorized that metastasis always coincides with a primary cancer, and, as such, is a tumor that started from a cancer cell or cells in another part of the body.

However, over 10% of patients presenting to oncology units will have metastases without a primary tumor found. In these cases, doctors refer to the primary tumor as "unknown" or "occult," and the patient is said to have cancer of unknown primary origin (CUP) or Unknown Primary Tumors (UPT). However, the use of

immunohistochemistry has permitted pathologists to give an identity to many of these metastases. However, imaging of the indicated area only occasionally reveals a primary. In rare cases (e.g., of melanoma), no primary tumor is found, even on autopsy. It is therefore thought that some primary tumors can regress completely, but leave their metastases behind. Despite the use of various techniques, in some cases the primary tumor remains unidentified.

The formation of metastasis or metastases (via the metastatic process) is deemed to be a multistep event and represents the most dreadful aspect of cancer. At the moment of diagnosis, cancers are frequently far advanced in their natural history, and the presence of metastases is a common event. In fact, approximately 30% of patients have detectable metastases at the moment of clinical diagnosis and a further 30% of patients have occult metastases. Metastases can be disseminated and they can infest different organs at the same time, or localize to a specific organ. In the case of localized disease, surgery is the treatment of choice; however recurrence and prognosis depend on many criteria such as: resectability, patient’s clinical situation, and number of metastases.

After resection, recurrence is common, suggesting that micrometastatic foci are present at the moment of diagnosis. Systemic chemotherapy is an ideal setting but only few patients are cured by it, and in the majority systemic chemotherapy fails. Many physiological barriers and pharmacokinetic parameters contribute to decrease its efficacy.

Liver, lungs and lymph nodes are filtration organs and therefore inclined to

metastasization. The poor chemosensitivity of metastases, peculiarly those of colorectal origin has forced many researchers to use methods for increasing the time and the concentration of drugs. The need for decreasing or limiting the side effects for this important and delicate organ led to the development of the technique of liver isolation for perfusion of antineoplastic agents. (K. R. Aigner, Isolated liver perfusion. In: Morris DL, McArdle CS, Onik GM, eds. Hepatic Metastases. Oxford: Butterworth Heinemann, 1996. 101-107). Since 1981 , modifications and technical improvements have been continuously introduced. Liver metastases may be of different origin and their chemosensitivity may vary according to the histological type and their response in presence of heat.

The terms cancer, breast cancer, lung cancer, head and neck cancer, prostate cancer, brain cancer, colorectal cancer, liver cancer, pancreatic cancer and malignant melanoma are known and understood in the art.

Prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow growing; however, there are cases of aggressive prostate cancers. The cancer cells may metastasize from the prostate to other parts of the body, particularly the bones and lymph nodes. The term prostate cancer preferably includes non-metastatic or metastatic prostate cancer. Even more preferably, the term prostate cancer includes androgen independent prostate cancer (AIPCa), androgen dependent prostate cancer (ADPCa), metastatic androgen independent prostate cancer and/or metastatic androgen dependent prostate cancer.

Colorectal cancer, less formally known as bowel cancer, is a cancer characterized by neoplasia in the colon, rectum, or vermiform appendix.

Liver cancer or hepatic cancer is properly considered to be a cancer which starts in the liver, as opposed to a cancer which originates in another organ and migrates to the liver, known as a liver metastasis. There are many forms of liver cancer, although many cancers found in the liver are metastases from other tumors, frequently of the Gl tract (like colon cancer, carcinoid tumors mainly of the appendix, etc.), but also from breast cancer, ovarian cancer, lung cancer, renal cancer, pancreatic cancer, prostate cancer, etc. The most frequent liver cancer is hepatocellular carcinoma (HCC). This tumor also has a variant type that consists of both HCC and

cholangiocarcinoma components. The cells of the bile duct coexist next to the bile ducts that drain the bile produced by the hepatocytes of the liver. Cancers which arise from the blood vessel cells in the liver are known has hemangioendotheliomas.

Pancreatic cancer is considered to be a cancer starting in the pancreas. There are a number of types of pancreatic cancer including pancreatic adenocarcinoma and non adenocarcinoma. Pancreatic adenocarcinoma typically has a very poor prognosis. The present invention surprisingly provides a high effective drug against pancreatic cancer.

Cancer of the pancreas represents about 3 % of newly diagnosed cancers, with the dominating subtype pancreatic ductal adenocarcinoma (PDAC) (Hezel et al. , (2006) "Genetics and biology of pancreatic ductal adenocarcinoma." Genes Dev 20(10): 1218-1249; Siegel et al., (2019) "Cancer statistics, 2019." CA Cancer J Clin 69(1 ): 7- 34). At the time of first diagnosis, only 10 to 20 % of PDACs is resectable (Bilimoria et al. (2007) "National failure to operate on early stage pancreatic cancer." Ann Sure 246(2): 173-180; Gillen et al., (2010) "Preoperative/neoadjuvant therapy in pancreatic cancer: a systematic review and meta-analysis of response and resection

percentages." PLoS Med 7(4): e1000267).

Pancreatic cancer is associated with a very poor prognosis, it has the lowest 5 year survival rate (8-9 %) when considering the average of all tumor stages. PDAC is the fourth leading cause of cancer death in the United States (Siegel et al., (2016) "Cancer statistics, 2016." CA Cancer J Clin 66(1 ): 7-30; Siegel et al., (2019) "Cancer statistics, 2019." CA Cancer J Clin 69(1 ): 7-34).

The most common genetic alterations in PDAC are found in KRAS, CDKN2A,

SMAD4 and TP53 (Bailey et al. (2016) "Genomic analyses identify molecular subtypes of pancreatic cancer." Nature 531 (7592): 47-52; Hezel et al. 2006). In addition, a number of other mutated genes including oncogenes BRAF and RET may drive tumor development (Grinshpun et al., (2019) "Beyond KRAS: Practical

Molecular Targets in Pancreatic Adenocarcinoma." Case Rep Oncol 12(1 ): 7-13).

At the time of diagnosis, more than half of the PDAC patients have metastases which are the major cause of death (Padoan et al., (2019) "Inflammation and Pancreatic Cancer: Focus on Metabolism, Cytokines, and Immunity." Int J Mol Sci 20(3); Werner et al., 2013). Following a successful surgical resection of the tumor, the majority of patients show recurrence of metastasis (Mayo et al., (2012) "Conditional survival in patients with pancreatic ductal adenocarcinoma resected with curative intent."

Cancer 118(10): 2674-2681 ; Neoptolemos et al., (2004) "A randomized trial of chemoradiotherapy and chemotherapy after resection of pancreatic cancer." N Engl J Med 350(12): 1200-1210). Early stage pancreatic cancer may be treated by surgery plus adjuvant chemotherapy using either 5-fluorouracil (5-FU) or gemcitabine (both: inhibitors of DNA synthesis) (Herreros-Villanueva et al. , (2012) "Adjuvant and neoadjuvant treatment in pancreatic cancer." World J Gastroenterol 18(14): 1565-1572). Patients who had initially non-resectable tumors (borderline resectable/unresectable) and underwent a neoadjuvant combination chemotherapy may increase the chance of resection and possibly improve survival outcome (Gillen et al., 2010). In the process of pancreatic resections, dissection of regional lymph nodes and of lymph nodes along the main arteries is included (Werner et al., 2013).

A number of different single and combined chemotherapies have been applied and, in addition, chemotherapy has been combined with radiotherapy, named

chemoradiation (Herreros-Villanueva et al., 2012; Werner et al., 2013). A failure to respond to chemotherapy which includes resistance to gemcitabine, 5-FU and/or cisplatin correlates with the rate of 63 genetic mutations on average in advanced pancreatic cancer, which may affect 12 different signaling pathways in the tumor cell (Jones et al., (2008) "Core Signaling Pathways in Human Pancreatic Cancers Revealed by Global Genomic Analyses." Science 321(5897): 1801 -1806). The nucleoside transporter hENT-1 is a predictive biomarker candidate for gemcitabine response since its over-expression appears to correlate with overall and disease-free survival of pancreas adenocarcinoma patients under gemcitabine treatment

(Greenhalf et al., (2014) "Pancreatic cancer hENT1 expression and survival from gemcitabine in patients from the ESPAC-3 trial." J Natl Cancer Inst 106(1 ): djt347; Farrell et al., (2009) "Human Equilibrative Nucleoside Transporter 1 Levels Predict Response to Gemcitabine in Patients With Pancreatic Cancer." Gastroenterology 136(1 ): 187-195).

The combination therapy regime named FOLFIRINOX which contains folinic acid (leukovorin), 5-FU, irinotecan and oxaliplatin has been applied as an alternative to gemcitabine treatment of PDAC. FOLFIRINOX treatment resulted in a prolonged survival time, however, it caused more toxic effects including neurotoxicity compared to gemcitabine (Conroy et al., (2011 ) "FOLFIRINOX versus gemcitabine for metastatic pancreatic cancer." N Engl J Med 364(19): 1817-1825; Vaccaro et al., (2015) "Metastatic pancreatic cancer: Is there a light at the end of the tunnel?" World J Gastroenterol 21 (16): 4788-4801 ). The efficiency of FOLFIRINOX treatment depended on the expression of CES2, a carboxyl esterase which is believed to activate irinotecan in the tumor and therefore could serve as a predictive biomarker for therapy (Capello et al. , (2015) "Carboxylesterase 2 as a Determinant of Response to Irinotecan and Neoadjuvant FOLFIRINOX Therapy in Pancreatic Ductal

Adenocarcinoma." J Natl Cancer Inst 107(8)).

A new formulation of the cancer drug paclitaxel not requiring a solvent, Nab- paclitaxel, consists of a nanoparticle with the protein albumin as a carrier. A combination therapy of Nab-paclitaxel with gemcitabine resulted in a prolonged survival time of 8.7 month compared to 6.6 month with gemcitabine alone (Goldstein et al., (2015) "nab-Paclitaxel plus gemcitabine for metastatic pancreatic cancer: long term survival from a phase III trial." J Natl Cancer Inst 107(2); Von Hoff et al., (2013) "Increased survival in pancreatic cancer with nab-paclitaxel plus gemcitabine." N Engl J Med 369(18): 1691 -1703).

A combination of chemotherapy, using 5-FU, gemcitabine and cisplatin, alone or in combination, with radiotherapy (chemoradiotherapy) may bring a benefit for the therapy of borderline resectable or unresectable diseases, where the treatment regime starts before resection (neoadjuvant chemoradiation) (Gillen et al., 2010; Regine et al., 2008; Werner et al., (2013) "Advanced-stage pancreatic cancer:

therapy options." Nature Reviews Clinical Oncology 10: 323).

A number of treatment studies for unresectable advanced pancreatic cancer were compared in a meta analysis (Chen et al., (2019) "Melanoma cell adhesion molecule is the driving force behind the dissemination of melanoma upon S100A8/A9 binding in the original skin lesion." Cancer Lett) where gemcitabine, as the standard treatment, was applied together with one additional treatment, a chemotherapeutic drug or an antibody; or a combination of gemcitabine with a second drug plus an antibody (cetuximab, anti-EGF receptor antibody; bevacizumab, antibody directed against VEGF). The chemotherapeutic drugs combined with gemcitabine include 5- FU (DNA synthesis inhibitor), cisplatin (crosslinks DNA, blocks cell division), capecitabin (is converted to 5-FU), axitinib (tyrosine kinase inhibitor), erlotinib (EGF receptor tyrosine kinase inhibitor), etanercept (inhibitor of TNF alpha), exatecan (topoisomerase inhibitor), irinotecan (topoisomerase inhibitor), marimastat (matrix metalloproteinase inhibitor), nab-paclitaxel (blocks cell division), pemetrexed (folate anti-metabolite), sorafenib (inhibitor of tyrosine- and Raf family kinases), tipifarnib (farnesyltransferase inhibitor), vismodegib (smoothened receptor inhibitor); these treatments were compared with gemcitabine alone; or with gemcitabine combined with radiotherapy; or with the combination therapy FOLFIRINOX. Five treatments showed the highest activity for overall survival; five combinations were most effective in progression-free survival; and the following four treatments were effective with both criteria: gemcitabine plus radiotherapy, gemcitabine plus erlotinib plus

bevacizumab, gemcitabine plus cisplatin, and gemcitabine plus capecitabin plus erlotinib (Chen et al. , 2019).

Malignant melanoma is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. They predominantly occur in skin, but are also found in other parts of the body, including the bowel and the eye (see uveal melanoma). Melanoma can occur in any part of the body that contains melanocytes. Melanoma is less common than other skin cancers. Flowever, it is much more dangerous and causes the majority (75%) of deaths related to skin cancer. Worldwide, doctors diagnose about 160,000 new cases of melanoma yearly.

Cutaneous melanoma represents 1.6 % of the newly diagnosed primary malignant tumors worldwide (Bray et al., (2018) "Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries." CA Cancer J Clin 68(6): 394-424). The risk to develop a melanoma is higher in the United States of America, Australia and Northern Europe compared to most other countries, new melanoma cases per year in the United States were estimated to 76,380 (Siegel et al., 2016).

The risk for melanoma is influenced by genetic factors but is induced by ultraviolet (UV) light exposure (Caini et al., (2009) "Meta-analysis of risk factors for cutaneous melanoma according to anatomical site and clinico-pathological variant." Eur J Cancer 45(17): 3054-3063; Gandini et al., (2005a) "Meta-analysis of risk factors for cutaneous melanoma: II. Sun exposure." Eur J Cancer 41(1 ): 45-60; Gandini et al., (2005b) "Meta-analysis of risk factors for cutaneous melanoma: III. Family history, actinic damage and phenotypic factors." Eur J Cancer 41(14): 2040-2059), either due to sunlight exposure or to UV-A emitting tanning-beds. Spreading of the primary melanoma resulting in metastasis results in a 10 year survival rate of less than 10 % (Balch et al. , (2001 ) "Final version of the American Joint Committee on Cancer staging system for cutaneous melanoma." J Clin Oncol 19(16): 3635-3648). The process of metastasis is incompletely understood, and recently it was shown to require the interaction of a specific cell adhesion molecule with its receptor and downstream signaling (Chen et al., 2019).

The number of mutations in melanoma is high compared to other cancers, with 100 mutations per 1 million base pairs in the tumor cell (Lawrence et al., (2013)

"Mutational heterogeneity in cancer and the search for new cancer-associated genes." Nature 499(7457): 214-218). Frequently mutated genes in melanoma are BRAF and NRAS (Curtin et al., (2005) "Distinct sets of genetic alterations in melanoma." N Engl J Med 353(20): 2135-2147). In addition, a number of mutated genes are considered as tumor-driving (“driver”) mutants, such as TERT, PTEN, TP53, CDKN2A, PREX2, EZH2, IDH1 HRAS, RAC1 and NF1 (Hodis et al., 2012; Reddy et al., (2017) "Somatic driver mutations in melanoma." Cancer 123(S11 ): 2104-2117). Other genes mutated during tumor development include KIT, GNA11 , GNAQ, CTNNB1 , PIK3CA and WT1 (Goldinger et al., (2013) "Targeted therapy in melanoma - the role of BRAF, RAS and KIT mutations." EJC Suppl 11 (2): 92-96; Hodis et al., 2012). In a 36 month follow up analysis of malignant melanomas, 21 out of 34 tumors developed nodal metastatic disease and showed changes in their gene expression including cell cycle, apoptosis, signal transduction and epithelial-to- mesenchymal transition (EMT), while in a second group of melanomas, the expression changes of certain EMT genes correlated with the development of metastasis (Alonso et al., (2007) "A high-throughput study in melanoma identifies epithelial-mesenchymal transition as a major determinant of metastasis." Cancer Res 67(7): 3450-3460).

The surgical removal of malignant melanomas detected at an early stage as a localized disease can lead to over 98.4 % of 5 year survival, while spreading to local or distal lymph nodes decreases the survival rate to 62.4 or 17.9 %, respectively (National Cancer Institute, 2016, Cancer Stat Facts: Melanoma of the Skin).

Dacarbazine (DTIC) has been the only cytotoxic chemotherapy approved by the United States FDA for treatment of metastatic melanoma. From a pooled analysis of 23 controlled studies, 15.3 % of the melanoma patients receiving dacarbazine showed an objective response (Lui et al. , (2007) "Treatments for metastatic melanoma: synthesis of evidence from randomized trials." Cancer Treat Rev 33(8): 665-680). Whether by this treatment (intravenous injection of dacarbazine) there is a survival benefit, however, has not been demonstrated (Bhatia et al., (2009)

"Treatment of metastatic melanoma: an overview." Oncology (Williston Park) 23(6): 488-496).

Temozolomide, an analog of dacarbazine which is administered orally has the advantage to penetrate into the brain and therefore might be used to treat or prevent brain metastases (Bhatia et al., 2009). In a clinical study comparing dacarbazine and temozolomide there was no significant difference between the two treatments in both the objective response rate and overall survival (Danson & Middleton, (2001 )

"Temozolomide: a novel oral alkylating agent." Expert Rev Anticancer Ther 1(1 ): 13- 19).

In phase II or phase III clinical studies, various combination chemotherapies, compared with dacarbazine or temozolomide alone, showed increased response rates but no significant extension of survival, and greater toxicity (Bhatia et al., 2009).

The cytokine IL-2 stimulates the growth and function of T cells and of natural killer (NK) cells. Among a total of 270 patients treated with high-dose bolus IL-2, the objective response rate was 16 %, with 6 % complete and 10 % partial response (Atkins et al., (1999) "High-dose recombinant interleukin 2 therapy for patients with metastatic melanoma: analysis of 270 patients treated between 1985 and 1993." J Clin Oncol 17(7): 2105-2116). About half of the complete responders were long term responders, with 44 % of responders surviving over 5 years (Atkins et al., 1999).

Interferon alpha 2b (pegylated; IFNalpha2b) is used in adjuvant therapy of resected high-risk melanoma. A meta analysis revealed that, compared to treatment without interferon, IFNalpha2b treatment resulted in a benefit in five years event-free survival (EFS) of 3.5 %, and overall survival (OS) of 3.0 % (Ives et al., 2017). This remarkable but weak effect, still leading to only 38 % survivors at five years and 31 % at ten years, contrasts with severe side effects of IFNalpha2b, especially at high doses.

Both IL-2 and IFNalpha2b have been tested in combination with cytotoxic drugs (biochemotherapy) in a number of studies but did not lead to an improvement in overall survival (Bhatia et al. , 2009).

Mutations in the BRAF gene at codon valine 600 (V600) are found in 66 % of malignant melanomas. The protein kinase BRAF is located at the top of a kinase cascade which stimulates cell proliferation. The development of BRAF kinase inhibitors such as vemurafenib and dabrafenib could serve as a major breakthrough in melanoma therapy. In a phase III clinical study, overall survival of 13.6 months was seen in the vemurafenib group compared to 9.7 months in the dacarbazine group (Singh et al., 2016).

The blockade of immune inhibitory molecules such as CTLA-4 or PD-1 and its ligand PD-L1 by specific antibodies appears as an attractive new approach to improve the immune response against cancers including melanoma. Clinical phase I and phase II studies have indicated that blocking CTLA-4 or PD-1/PD-L1 has distinct effects, with clear improvements in objective response rate and overall survival of melanoma patients (Singh et al., 2016).

Lymphomas are derived from B lymphocytes (B cells), or from T lymphocytes or NK cells. The systematic classification divides lymphomas into two groups, Hodgkin lymphomas and non-Hodgkin lymphomas (NHL). The non-Hodgkin lymphomas, originating from B cells (in 85% of cases) which account for about 4% of all cancers in the Unites States, mostly derive from B lymphocytes and constitute a complex group of more than 30 diseases. B cell-derived lymphomas originate from defined states of B cell development in the secondary lymphatic organs which starts from naive B cells and results in memory B cells or in antibody-producing plasma cells, respectively (Seifert et al., 2019). Epstein-Barr virus (EBV), a common human Herpes virus with an infection preference for mucosal epithelial cells and B cells, is associated with the development of lymphoproliferative diseases and lymphomas such as Burkitt lymphoma (Shannon-Lowe et al., 2017).

Chronic lymphocytic lymphomas (CLL) may derive from early state B cells (before somatic mutation) or from memory B cells (later stage); Burkitt lymphoma and Follicular lymphoma both develop from early stage, before somatic mutation of B cells; Mantle cell lymphomas derive from mantle cells; and lymphoplasmacytic lymphoma stems from plasma blasts, cells in late phase of B cell development (Seifert et al., 2019).

Therapies for NHL and CLL (B cell-derived lymphomas) vary for each tumor subtype. Chemotherapy remains an important treatment for some lymphomas, in some cases, surgery or radiation therapy may be considered. The antibody rituximab directed against CD20, a surface protein present on B cells in most development phases, has shown significant activity in clinical studies. By binding to CD20 on lymphoma cells, the antibody may induce cell death by complement-dependent cytotoxicity (CDC) or by antibody-dependent cell-mediated cytotoxicity (ADCC). Rituximab has been used to treat various NHL diseases in different disease stages (Mohammed et al., 2019). For aggressive diseases, rituximab may be combined with a chemotherapy treatment regime such as CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone).

Cell cultivation

Adherent cells are cultured in the respective medium in cell culture flasks or cell culture plates. For passages, the cells are washed with PBS, incubated with biotase or trypsin for 5 to 10 min at 37 degrees Celsius, centrifuged at a maximum of 130 g, counted and reseeded in a certain cell count per area or per ml of medium.

Suspension cells are also cultured in cell culture flasks or cell culture plates. For the reaction, they are diluted without enzyme treatment in fresh culture medium.

Isolation and handling of cell suspensions for FACS analysis MEC-1 cells are cultured in MEC-1 culture medium at 37 degrees Celsius and 5% CO2. For induction with peptides, 0.8x10 ⁶ to 1x10 ⁶ cells are seeded in each well of 48-well plates.

Fluman lymphocytes are obtained as peripheral blood mononuclear cells ("PBMC") from whole blood. For this purpose, 15 ml of heparinized whole blood (heparin tube, Sarstedt) were layered on 15 ml Biocoll in LeucoSep tubes and obtained by centrifugation (10 min at 120 g) as the top layer ("lymphocytes") and so separated from other cells. For induction with peptides, 1x106 lymphocytes are seeded into each well of the 48-well plates.

After addition of the peptides diluted in culture medium to the cells (MEC-1 or lymphocytes) in the respective cavity, the cells are cultured for 2 to 4 hours at 37 degrees Celsius and 5% C02. The cell suspension is centrifuged in centrifuge tubes at 120 g, the cells are suspended in 500 pi serum-free culture medium, then 1.5 ml of cold 80% ethanol (ethanol / PBS-80/20, v / v; stored at -20 degrees Celsius) is added, the FACS tubes sealed and stored at -20 degrees Celsius for a maximum of 18 h. The cells are centrifuged for 5 min at 120 g and suspended in 2 ml PBS, then incubated for 30 min at 37 degrees Celsius. After renewed centrifugation, the cells are suspended in 0.5 ml DAPI solution and incubated for 15 min at 20 degrees Celsius in the dark. Thereafter, the cells are stored dark for a maximum of four hours in an ice bath, then the FACS analysis.

Implementation of the cell cultivation and harvesting of adherent cells for FACS analysis

For each cell line, the indicated culture medium is used in each case (A375- or BxPC-3 culture medium; or MEC-1 - or lymphocyte culture medium, or MDA-MB-231 culture medium) the following it is generally referred to as culture medium. The cells are cultured at 37 degrees Celsius and 5% CO2. Alternatively, two protocols are used for the preparation and execution of the FACS analyzes.

Protocol A: To transfer adherent cells (A375 and BxPC-3 cells) after culture, cells are washed twice with PBS. To detach the cells, the enzyme biotase is used according to the manufacturer's instructions. For this purpose, after washing with PBS, the cells are mixed with biotase (5 ml of biotase solution per 75 cm ² surface of the cell culture bottles) and incubated for 5 min at 37 degrees Celsius, and the biotase is separated by centrifugation. Cells cultivated in suspension (MEC-1 and lymphocytes) were transferred by dilution. The cells are suspended in culture medium and counted, each time 1.5x10 ⁵ cells/cm ² are seeded in 48-well plates and cultured for between 1.5 and 24 hours at 37 degrees Celsius, 5% CO2. Peptides are pre-diluted from stock solution with culture medium and 200 pi of peptide solution added so that final concentrations of 30 to 500 mM peptide are present in at most 1 % (v / v) DMSO. As control solutions, culture medium without peptide (DMSO-containing) in culture medium or etoposide solution is added. After incubating the cells for several hours, the cell supernatant is transferred to a FACS tube for each batch and, after washing the cells with PBS, the wash solution is added. Then the cells are incubated with 200 mI of biotase solution for 10 min, 37 °C, the cells with the biotase are also transferred to the FACS tube and the cells are collected by centrifugation for 5 min. The cell pellet is suspended in 500 mI of serum-free culture medium, then 1.5 ml of cold 80% ethanol (ethanol / PBS- 80/20, v / v, stored at -20 °C) is added, the FACS tubes sealed and stored at -20 degrees Celsius for 15 to 18 h. Thereafter, the cells are centrifuged for 5 minutes at 120 g, suspended after removal of the supernatant in 2 ml PBS and incubated at 37 degrees Celsius for 30 minutes. After re-centrifugation, the cells are suspended in 0.5 ml DAPI solution and incubated for 15 min at 20 degrees Celsius in the dark. Thereafter, the cells are stored dark for a maximum of four hours in an ice bath, followed by the FACS analysis.

Protocol B:

The adherent cells (A375 and BxPC-3 cells and MDA-MB-231 , respectively) are seeded 24 hours before induction in 6-well plates in culture medium. For this, the cells are washed with PBS, then incubated with trypsin / EDTA solution at 37 degrees Celsius and suspended in culture medium. The 6-well plates are loaded with 1x10 ⁵ cells / cm ² in culture medium and the cells incubated for 24 hours until induction with the peptides in the incubator. For induction, the peptides are diluted in fresh culture medium. As control solutions, culture medium without peptide (DMSO- containing) in culture medium or etoposide solution is added. The cells are washed with PBS. Thereafter the peptide solution in culture medium is added to the cells. After incubation in the incubator (37 °C., 5% CO2) between 1.5 and 24 hours, the cell supernatant is transferred to 15 ml centrifuge tubes, the cells are washed with 0.75 ml PBS and then with 0.5 ml versene solution. Both washings are combined with the cell supernatant. The cells are then added with 0.5 ml of trypsin / EDTA solution and incubated at about 37 °C for at most 10 minutes until the cells detached. The cell suspension is combined with cell supernatant and washings and centrifuged at about 130 g for about 10 minutes. After removing the supernatant, the cells are suspended in 400 pi of cell culture medium (without serum) and mixed with 1.2 ml of 80% ethanol / 20% PBS (v / v) and incubated for 1 to 7 days at -20 ° C. For analysis, the cells are centrifuged at 130 g for 10 min, suspended in 2 ml PBS, and centrifuged again for 5 min. The cells are suspended in 700 mI PI buffer and incubated for 10 min at 37 ° C in the dark. Subsequently, the cells are stored dark for a maximum of four hours in an ice bath, then the FACS analysis is performed.

Evaluation of the results of the FACS analysis

The proportion of cells which have died was determined by two methods, both rely on the analysis of cells by flow cytometry, often called FACS analysis. This technology allows to determine the physical and chemical properties of both normal cells and tumor cells. The cells can be labelled by fluorescent dyes, which may bind to cellular DNA or which are coupled to antibodies that bind to proteins or other structures on the cell surface or inside the cells. The cells are suspended and injected into a flow cytometer instrument and, ideally one at a time, the cells flow through a laser beam. The laser light is either scattered or elicits fluorescence at the dyes which were applied and the scattered and the fluorescent light is analyzed by an optical and light detection system. This system with an array of dichroic mirrors or prisms and optical filters serves to direct the light to photomultipliers that are mounted in defined positions, either in line of the laser and the position where the cell meets the laser beam, thereby delivering signals of the forward-scattered light (FSC); or photomultipliers detect light which is scattered in an angle relative to the FSC beam direction, to detect the side-scattered light (SSC), or to detect selected wave length from fluorescent light. Programmed cell death (apoptosis) can be detected by changes of the FSC/SSC light scattering pattern, or by the appearance of cells with a low DNA content, as revealed by the so called subG1 peak (Darzynkiewicz et al. , 1992; Vermes et al., 2000; see below). Further information and useful handling instructions are available in Shapiro, FI. M.“Practical Flow Cytometry”, 4th Edition, Beckman Coulter Life Sciences, ISBN: 978-0-471 -41 125-3, (2003), eBook, https://www.beckman.com/resources/reading-material/ebooks/pr actical-flow- cytometry/

Flow cytometers:

For suspension cells (MEC-1 and lymphocytes/PBMC) and for adherent cells analyzed according to Protocol A, FACS analysis to determine subG1 cell cycle and vital cell fractions was done on a Becton Dickinson LSR Fortessa flow cytometer.

The analysis by FACS including subG1 and vital cell analysis according to protocol B was performed with a Cytomics FC 500 MPL flow cytometer from Beckman Coulter.

Vital Cells analysis:

Changes of the cell form during cell death by apoptosis are documented in the literature (Lizard et al. 1995; Taga et al. 2000; Vermes et al., 2000). The protocols for cell cultivation, treatment and preparation of the cells before flow cytometry is detailed in separate examples. Cell suspensions of cell lines A375, BxPC-3, MEC-1 or of primary lymphocytes (see separate example of lymphocyte preparation) are analyzed by flow cytometry. The data are further analyzed by using the program “Flowing Software 2”. The data of light scattering are drawn in a two-dimensional FSC/SSC plot. Since the position in the FSC/SSC plot of apoptotic cells changes relative to non-apoptotic cells (Vermes et al., 2000), a region (R-1 ) is drawn representing mainly non-apoptotic cells and excluding cells with both low FSC and low SSC values and excluding cells with high values of FSC and/or SSC (Fig. 1 ). The regions are individually selected for each cell type (A375, BxPC-3, MEC-1 and primary lymphocytes). The percentage of untreated non-apoptotic cells in the region R-1 relative to total cells is set to 100 %, representing 100 % vital cells. The fraction (%) of cells in R-1 relative to the total number of cells in case of cell treatment by certain peptides or by cytotoxic drugs results in cell vitality, below 100 %, thereby indicating a loss of cell vitality by the treatment.

The analysis of the normal cell form after appropriate treatment with a peptide is carried out by determining the percentage of cells in the region R-1 in the diagram (application Forward Scatter versus Sideward Scatter). The reference is the percentage of cells in R-1 without peptide addition (solvent DMSO only). Flere, the proportion of cells without peptide addition in region R-1 was set as "100% normal cell shape", which corresponds to 100% vitality. At values less than 100% in R-1 , the proportion of vital cells decreases accordingly.

Cell cycle analysis (subG1 values)

The second method analyzes the cell cycle phases which is drawn from the relative DNA content. Cells labeled by a fluorescent dye, using either DAPI or propidium iodide (PI) were analyzed by a cell sorter. The protocols for cell cultivation, treatment and preparation and staining of the cells for the flow cytometry is given in separate examples. Following flow cytometry, the frequency of fluorescence intensities which is proportional to the DNA content is plotted in a single dimension histogram, which reveals whether the cells are either in the Go/G1 phase (resting cells); or the cells proliferate and are in the DNA synthesis (S) phase or in the G2/M phase which is before or at the time of cell division (mitosis). When cells die by apoptosis, cellular changes lead to diminished DNA content resulting in a new peak located before the Go/G1 peak, often called“subG1” peak (Broecker-Preuss et al. 2015; Darzynkiewicz et al., 1992; Dbaibo et al. 1998; Fischbeck et al. 2011 ).

The“Flowing Software 2” program is used to draw from the raw data of the flow cytometer an FSC/SSC plot. This first step is performed in order to analyze a selected cell fraction excluding cells with both small FSC and small SSC values. Therefore, a gating area is drawn in a two-dimensional FSC/SSC plot (region R-1 ) which contains mainly intact cells, but no small vesicles. This is initially done for each cell type using reference cells which were not incubated with substances inducing cell death. The geometry applied for region R-1 is usually a pentagon, as shown in Figure 1. By this selection of the cell fraction, a bias is prevented which would include a very high number of small cellular vesicles (apoptotic bodies) that are formed by membrane blebbing from dying cells, which have a low DNA content but which, by their large number, would increase the fraction of presumptive subG1 cells. Next, a one dimensional plot analyzing only this gated cell fraction is drawn which shows the distribution of the DNA content and, in case of the untreated control cells, gives a typical cell cycle profile with Go/G1 -, S- and G2/M phases. In this DNA content plot, an analytical region is drawn in the area of lower DNA content to count the cells that show a subG1 peak, as illustrated in Fig. 1. The fraction of apoptotic cells is defined as the fraction of cells with DNA content in the subG1 region as part of the total number of cells in the DNA content plot (Fig. 1 ).

In the plot of side-scattered light (SSC) versus forward-scattered light (FSC), the full scale linear plot for each, SSC and FSC, was normalized to 100 %. As shown in Figure 1 , 100% corresponds to an intensity value of 262114 units.

The coordinates for the corner points (ml to m5) of the analysis of adherent cells (A375 and BxPC-3) according to protocol A (data from the Becton Dickinson flow cytometer) were as follows. Percent of full scale for SSC (S) and FSC (F),

respectively: ml (S=23.1 %, F=50.0 %); m2 (S=34.6 %, F=37.3 %); m3 (S=59.6 %, F=51.9); m4 (S=57.7 %, F=77.7 %); m5 (S=38.5 %, F=36.9 %).

The coordinates for the corner points (ml to m5) of the analysis of MEC-1 cells according to protocol A (data from the Becton Dickinson flow cytometer) were as follows. Percent of full scale for SSC (S) and FSC (F), respectively: ml (S=6.9 %,

F=18.1 %); m2 (S=68.1 %, F=30.8 %); m3 (S=55.8 %, F=52.7 %); m4 (S=28.9 %, F=44.2 %); m5 (S=10.0 %, F=28.5 %).

The coordinates for the corner points (ml to m5) of the analysis of lymphocytes (PBMC) according to protocol A (data from the Becton Dickinson flow cytometer) were as follows. Percent of full scale for SSC (S) and FSC (F), respectively: ml , (S=3.1 %, F=16.9 %); m2 (S=27.3 %, F=40.4 %); m3 (S=66.5 %, F=53.9 %); m4 (S=14.2 %, F=73.1 %); m5 (S=3.5 %, F=39,2 %). The coordinates for the corner markers (ml to m5) of the analysis of A375 and BxPC-3 cells according to protocol B (data from the Beckman Coulter flow cytometer) were as follows. Percent of full scale for SSC (S) and FSC (F), respectively: ml (S=18%, F=17%); m2 (S=40%, F=37%); m3 (S=35%, F=59%); m4 (S=15%, F=57%); m5 (S=9%, F=36%).

Analysis of FACS measurements is performed using the Flowing Software, version 2.5.1 (Turku Center for Biotechnology, University of Turku, Finland). The files of each FACS analysis are opened as FCS files in the "Flowing Software" program in an "analysis" subprogram. In this case, a two-dimensional application of Forward

Scanner (FSC-A) against Sideward Scanner (SSC-A) is used. By comparing the profiles of the respective cell type under normal conditions, i.e. without apoptosis- inducing substances, an area or a region is preferably determined. The determination of the region is well known in the art as mentioned above and below. Preferably a pentagon is determined, which covers a substantial part of the measurement points. The coordinates of the pentagon are given in the previous section (“Vital Cells analysis”). Then this setting is saved as a mask ("analysis", for example with "region R-1 ") for further analysis. This mask ("region R-1 ") is used for the whole Example as mentioned above and below.

The evaluation of the FACS analysis to determine the subG1 data was also carried out with the program Flowing Software, version 2.5.1. The fluorescence in the respective analysis channel for DAPI or propidium iodide was plotted as a histogram, the data from the respectively defined region R-1 being utilized (see FIG. 1 ). In addition to the regions for G1 + S and G2 / M (FI-5 and H6), the region for cells in the apoptotic subG1 phase was determined at lower intensities (in Fig. 1 : to the left of H5, here FI-4). This histogram was assigned a statistics table, the percentage of cells with subG1 signals was determined as% of Vis in the FI-4 region.

Cultivation and evaluation of cells concerning the respiration activity

The cultivation of MDA-MB-231 cells in DMEM medium with 10% (v / v) FCS is done as described above and below in more detail (preferably according to Protocol B). The ATP concentrations are determined following treatment of the cells with peptides for 24 to 48 h, as indicated.“% Respiration-active cells" is the ATP concentration relative to cells without peptide treatment (100%).

ATP concentrations in the cavities where the cells grow was determined by the ATPlite 1 step Luminescence Assay System, an ATP Assay Kit from PerkinElmer. The assay relies on ATP which is released from the cells to start the reaction of the enzyme luciferase from firefly which converts D-luciferin, ATP (adenosine triphosphate) and oxygen (O2) to oxyluciferin, carbon dioxide (CO2) and

pyrophosphate (diphosphate); and light emitted as luminescence, which is read by a luminometer or other device which can read and quantify the light signal. The resulting luminescence was analyzed on a Berthold TriStar ² LB 942 Microplate Reader.

The following peptides are used in the Examples

The peptides were synthesized by CASLO ApS, Kongens Lyngby, Denmark, or by EMC microcollections GmbFI, Ttibingen, Germany. Purity was > 95 %, chloride was the counterion; purity was confirmed by High Pressure Liquid Chromatograpy

(HPLC).

The apoptosis efficiency of peptide SEQID NO 41 is measured using the subG1 method mentioned above at a concentration of the peptide of about 50 pM and an incubation time of about 24 hours. The data obtained are depicted Figure 19.

The evaluation of Examples 190 to 192 clearly shows an astonishing improvement of the apoptosis efficiency of the inventive pharmaceutically active substances.

Especially, Example 192 demonstrates an at least double efficiency of Peptide SEQID No 41 in view of Peptide SEQ No 27 and Peptide SEQ No 28 although the same molar amount of binding sites are present. This clearly shows an unexpected improvement of peptides comprising two, three, four, five or more of the first peptide portion, of the second peptide portion and/or of the third peptide portion, especially comprising two, three, four, five or more of the first peptide portion.
