Combination comprising HDAC inhibitor and CD137 agonist for cancer therapy

Field of application of the invention

The invention relates to medical applications of an HDAC inhibitor in combination with a CD137 agonist in the treatment of cancer.

Known technical background

CD137 is an inducible costimulatory receptor expressed on activated T and natural killer (NK) cells from the family of tumor necrosis factor receptors, and is also known as "tumor necrosis factor receptor superfamily member 9" (TNFRSF9), 4-1 BB and "induced by lymphocyte activation" (ILA). CD137 ligation on T cells triggers a signaling cascade that results in upregulation of antiapoptotic molecules, cytokine secretion, and enhanced effector function. In dysfunctional T cells that have a decreased cytotoxic capacity, 4-1 BB ligation demonstrates a potent ability to restore effector functions (Chester et al, 2018, Blood, 131 , 49-57).

Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl groups from specific histone sites in particular at promotor and enhancer regions, which is an essential part of regulation of cellular gene transcription. HDACs also regulate gene expression in an indirect fashion by mediating the acetylation of non-histone proteins such as DNA-binding proteins, transcription factors, signal transducers, DNA repair and chaperon proteins (Ververis K et al., Biologies: Targets and Therapy 7: 47-60, 2013; Vitt D et al., Targeting histone acetylation. In: RSC Drug Discovery Series No. 48: Epigenetics for Drug Discovery. Editor: Nessa Carey. The Royal Society of Chemistry, 2016).

HDAC inhibitors have been described to cause growth arrest with subsequent differentiation or apoptosis of tumor cells, whereas normal cells are not affected. As summarized in a review article by Marks et al. (Nature Reviews Cancer, 2001 , Volume 1 , page 194-202), HDAC inhibitors cause cell-cycle arrest in G1 and/or G2 phase. Growth-inhibitory effects have been documented in vitro in virtually all transformed cell types, including cell lines that arise from both hematological and epithelial tumors. The growth inhibitory cellular mechanism of the HDAC inhibitors has been described as a specific induction of expression of the cell cycle inhibitor CDKN1A (p21 ). Additionally, this review article summarizes the induction of growth arrest in tumor-bearing mice by HDAC inhibitors. Efficacy of HDAC inhibitors has been demonstrated in animal models of diverse cancer types such as breast, prostate, lung and stomach cancers, neuroblastoma and leukemia.

Treatments of many cancer types by HDAC inhibitors have been described in the available literature. HDAC inhibition has an effect on the expression of a number of proteins playing pivotal roles in tumor-relevant processes, such as HER2/neu, VEGF, raf-1 , cyclin A and B, Bax, Bad, p53, c-myc, Caspase 3, p21 and ERot. According to a review by Villar-Garea et al. (Int. J. Cancer: 112, 171-178 (2004)) cancer is understood to be an epigenetic as well as a genetic disease and the main goal using HDAC inhibitors would be restoration of gene expression of those tumor-suppressor genes that have been transcriptionally silenced by promotor- associated histone deacetylation. Drummond et al. (Annu. Rev. Pharmacol. Toxicol. 2005. 45:495-528) review the molecular mechanism and outcome of histone and non-histone substrates in cancer cells, which are effectors of HDAC, while HDAC also facilitates the acetylation of several key proteins other than histones. According to said review, acetylation is a key posttranslational modification of many proteins responsible for regulating critical intracellular pathways, and many of these substrates are tissue/development specific (EKLF, GATA-1 , ERa, MyoD), oncogenic (c-Myb), tumor-suppressing (p53), or even rather ubiquitous (TFIIE, TFIIF, TCF, HNF-4) transcription factors. Modulation of those proteins can lead to induction of cell cycle arrest, differentiation and apoptosis, all of which are desirable mechanisms for treatment of cancer. Kelly et al. (Expert Opin Invest Drugs, 1 1 (12), 2002) provides a further review on HDAC inhibitors in general and their application in cancer therapy.

The official US NIH website http://clinicaltrials.gov lists (status: February 2016) 545 clinical trials for cancer indications treated with HDAC inhibitors, among others various forms of leukemia (e.g. CML, CLL, AML), myelodysplastic syndrome, lymphoma including non-hodgkin’s lymphoma, multiple myeloma, plasma cell neoplasm, solid tumors in general, small intestine cancer, mesothelioma, prostate, breast (male and female), lung cancer (including non-small and small cell), neuroendocrine, malignant epithelial neoplasms, pancreas, skin cancer (including melanoma), multiple myeloma, cervix, renal cell, head and neck, gastric, ovarian, liver cancer, colon, rectal, thymoma, fallopian tube, peritoneal, nasopharyngeal, vestibular schwannoma, meningioma, acoustic neuroma, neurofibromatosis type 2, thyroid, urothelial, gliomas, brain, esophagus, astrocytoma, anaplastic oligodendroglioma, giant cell glioblastoma, glioblastoma, gliosarcoma, mixed glioma and brain neoplasm.

4SC-202 (E)-N-(2-aminophenyl)-3-(1 -((4-(1 -methyl-1 H-pyrazol-4-yl)phenyl)sulfonyl)-1 H- pyrrol-3-yl)acrylamide is an orally available HDAC inhibitor histone-deacetylase (HDAC) inhibitor. 4SC-202 has been evaluated in a Phase I clinical trial (TOPAS) in 24 heavily pre-treated patients with different types of blood cancer. 4SC-202 was well tolerated with few and/or manageable adverse events. Positive signs of anti-tumor efficacy were observed with one complete remission for 28 months and one partial responder for 8 months. Findings also exhibited disease control in 83% of the patients and long-term stabilization in 50% of patients.

Pharmaceuticals, Germany. Certain specific anticalins are the ones detailed in WO

2016/177762 A1 , WO 2016/177802 or WO 2016/184882.

A particular ELISA useable in this context, in particular for biologicals, more particularly for antibodies, is the following assay:

Material & Methods:

Substrate Solution by Thermo #34029) • Blocking solution: 1% BSA in PBS

• Washing solution: PBS with 0.05% Tween

• Stopping solution: sulphuric acid 250 mM 1. dissolve 0.1 - 1 pg/mL recombinant CD137, extracellular part of CD137 or chimeric proteins comprising extracellular part of CD137 in PBS, add 100 pL of said solution per well to ELISA 96 well plates, incubate the plates for 12-24h at 4°C (to coat the wells with CD137)

2. subsequently, remove solution and wash each well twice with 200 pL washing solution

3. subsequently add 200 pL of blocking solution per well, incubate at room temperature (about 22 °C) for 1 hour

4. subsequently, remove blocking solution and wash each well with 1 x 200 pL washing solution

5. subsequently, add 100 pL serial dilutions of CD137 agonist in PBS with 1 %BSA to the respective wells (a particularly suitable range of serial dilutions could comprise 1 pM, 0.5 pM, 0.25 pM, 0.125 pM, 0.06 pM, 0.03 pM, 0.015 pM, 8 nM, 4 nM, 2 nM, 1 nM, 0.3 nM,

0.1 nM, 0.03 nM, 0.01 nM, 0.003 nM and 0.001 nM), incubate for 1 hour at room temperature

12. plot data as relative absorption at 450 nm versus CD137 agonist concentration and calculate EC5 ₀ values using a suitable curve fit to a suitable pharmacological model (e.g. Emax model) using a suitable software (e.g. Graphpad Prism). For instance, recombinant anti-CD137 and capture antibody can be, in specific forms of the assay: Goat anti-human IgG H&L (HRP): Abeam, ab6858; Recombinant Human 4

1 BB/TNFRSF9/CD137: R&D Systems 9220-4B. Alternatively, the CD137 agonist can be biotinylated using e.g. the Biotin (type B) conjugation Kit (Abeam, ab102867 according to manufacturer’s instructions and detected using a Streptavidin-HRP conjugate, e g. Streptavidin (HRP) (Abeam, ab7403).

Alternative competition format: The above assay procedure can be run in the competition format which is e.g. suitable to determine binding of small molecule CD137 agonists.

In step 5, add serial dilutions of CD137 agonists (a particularly suitable range of serial dilutions could comprise 1 mM, 0.5 mM, 0.25 pM, 0.125 pM, 0.06 pM, 0.03 pM, 0.015 pM, 8 nM, 4 nM, 2 nM, 1 nM, 0.3 nM, 0.1 nM, 0.03 nM, 0.01 nM, 0.003 nM and 0.001 nM)and add recombinant CD137 ligand (e.g. in serial dilutions in a matrix pattern versus serial dilutions of CD137 agonists to determine suitable concentration of CD137 ligand, which may be in a similar range as the aforementioned dilutions). In step 7, the capture antibody is specific for the recombinant CD137 ligand. Suitable IC ₅ o values are 100 nM or lower, particularly 75 nM or lower, more particularly 50 nM or lower.

The CD137 agonists may be small molecules (having a molecular weight of about 600 or lower, particularly 500 or lower, more particularly 400 or lower) or biologicals (as used herein such as antibodies, modified antibodies, antibody fragments and other proteins, e.g.

anticalins).

In particular embodiments, the CD137 agonist is an antibody, more particularly a human antibody or a humanized antibody.

The CD137 agonist may be administered in a fixed dose, which means a dose that is equally administered to every patient that does not take into account the respective patient’s body weight, in particular in the case of a biomolecule like an antibody or an anticalin.

The CD137 agonist is to be administered in a dose that is typically used by the physician for the respective CD137 agonist, in particular the dose approved by the respective

governmental authorities. Typically, CD137 agonists that are biologicals (such as antibodies, modified antibodies, antibody fragments and other proteins) are to be administered only on day one of a treatment cycle, which may be a particular treatment cycle as described herein. This is due to their long half-life in the patient’s system.

The term antibody in the meaning of the invention comprises all antibodies, antibody fragments, and derivatives thereof that are capable of binding to an antigen, in this case CD137. This encompasses the complete monoclonal antibodies and also the epitope-binding fragments of these antibodies. In this connection, the epitope binding fragments (also referred to herein as antibody fragments or antibody derivatives) comprise all regions of the antibody that are capable of binding to the antigen. Examples of particular antibody fragments in accordance with the invention comprise, but expressly are not limited to, Fab, Fab', F(ab')2, Fd, individual chain (single chain) variable fragments (scFv), single-chain antibodies, disulfide-linked variable fragments (sdFv), and fragments that either contain a variable region of the light chain (VL) or a variable region of the heavy chain (VH). Moreover, they include recombinantly prepared antibodies, such as diabodies, and tetrabodies.

Antibody fragments contain the variable regions either alone or in combination with further regions that are selected from the hinge region and the first, second and third regions of the constant region (CH1 , CH2, CH3). Also, the term antibody comprises chimeric antibodies in which different regions of the antibody originate from different species, for example, antibodies with a murine variable region combined with a human constant region.

Antibody fragments are optionally linked with each other by a linker. The linker comprises a short (particularly 10 to 20 amino acid residues), flexible peptide sequence that is selected such that the antibody fragment has such a three-dimensional folding of VL and VH that it exhibits the antigen specificity of the complete antibody. Particular linkers are glycine-serine linkers with the structure (Gly _x Ser _y ) with x and y selected from 1 to 10, particularly 3 to 5. Moreover, particular linkers are comprised of a peptide sequence that can increase the protease resistance of the antibody derivatives.

The treatment cycles as described herein can be repeated one or more times, and typically are repeated as often as necessary, which is typically to be determined by the physician, e.g. based on the disease state (progressive disease, stable disease, tumor regression, etc.), and/or the tolerability of the treatment.

In certain embodiments, the HDAC inhibitor may in each case be administered to a patient in a n on-fasted state.

In certain embodiments, the cancer is a solid or hematological tumor;

In particular,“refractory” means no stabilization is achieved with therapy,“non-responding” means the best response achieved with therapy is stable disease for 6 months or less followed by disease progression,“relapsed” means temporary response shrinkage followed by disease progression, and wherein disease status including response, progression, stabilization may be determined e.g. according to RECIST or immune related RECIST (irRECIST) criteria version- reference Eisenhauer et al. 2009 Eur J Cancer, 45, 228-247; Nishino M et al., Clin Cancer Res. 2013, Jul 15; 19(14):3936-4 3). In certain particular embodiments, the cancer is an immunologically hot cancer.

and the salts thereof.

In an embodiment of the foregoing, exemplary compounds according to this invention may especially include any one selected from the group consisting of the compounds 2, 4, 7, 16, 26, 28, 32, 33, 38, 42 and 46 as mentioned afore, and the salts thereof.

As used herein, 4SC-202 and (E)-N-(2-aminophenyl)-3-(1-((4-(1 -methyl-1 H-pyrazol-4- yl)phenyl)sulfonyl)-1 H-pyrrol-3-yl)acrylamide (its chemical name) are used interchangeably and both refer to a compound of the following formula:

Suitable salts for the HDAC inhibitor are acid addition salts or salts with bases. Particular mention may be made of the pharmacologically tolerable inorganic and organic acids and bases customarily used in pharmacy. Those suitable are, on the one hand, water-insoluble and, particularly, water-soluble acid addition salts, the acids being employed in salt preparation in an equimolar quantitative ratio or one differing therefrom, particularly in an equimolar quantita- tive ratio. On the other hand, salts with bases are - depending on substitution - also suitable, the bases being employed in salt preparation in an equimolar quantitative ratio or one differing therefrom. Pharmacologically intolerable salts, which can be obtained, for example, as process products during the preparation of the HDAC inhibitor on an industrial scale, are converted into pharmacologically tolerable salts by processes known to the person skilled in the art. According to the invention, the HDAC inhibitor as well as its salts may contain, e.g. when isolated in crystalline form, varying amounts of solvents. Included within the scope of the present invention are therefore all solvates and in particular all hydrates of the HDAC inhibitor as well as all solvates and in particular all hydrates of the HDAC inhibitor, in particular such solvates or hydrates comprising about 0.5, 1 or 2 solvate or water molecules per molecule of the HDAC inhibitor or salts thereof.

Particular salts in the context of the present invention are the salts of 4SC-202 with, HBr, methansulfonic acid, hemiethane-1 ,2-disulfonic acid, benzenesulfonic acid, toluenesulfonic acid and 2-naphthalenesulfonic acid, more particularly toluenesulfonic acid, in particular in a molar ratio of about 1 : 1.

The HDAC inhibitor, in particular 4SC-202 and salts thereof can be prepared, for example, as described in detail in WO 2006/097474 A1 and WO 2009/112522 A1 , respectively.

The ability of CD137 agonists which are biologicals, e.g. antibodies, to bind to CD137 can be assessed by in vitro/ in vivo and/or cell-based assays either using purified domains of the target proteins or cells using ELISA or flow cytometry methods with a wide array of assays, e.g. the ELISA assay as described herein.

Urelumab (BMS-663513) is a humanized agonistic monoclonal lgG4 with a hinge mutation (S228P) antibody. At the determined maximum tolerated dose of 0.1 mg/kg every 3 weeks, urelumab was relatively well tolerated, with fatigue (16%) and nausea (13%) being the most common treatment-related AEs, and was associated with immunologic and pharmacodynamic activity demonstrated by the induction of IFN-inducible genes and cytokines (Segal et al, 2017, Clinical Cancer Research, 23, 1929-1936).

Utomilumab (PF-05082566) is a fully human lgG2 mAb agonist of the T-cell costimulatory receptor 4-1 BB / CD137.

The biological and medicinal properties of the HDAC inhibitor according to the present invention, in particular 4SC-202, and its respective salts, as well as for the CD137 agonists, are described in detail in the prior art, including but not limited to the references cited herein.

In certain embodiments of the present invention, the HDAC inhibitor and the CD137 agonist may be administered simultaneously, sequentially or separately. Administration of the HDAC inhibitor may in certain embodiments be within 30 minutes after a breakfast or light breakfast or within 30 minutes after a dinner or light dinner.

In the further context of the present invention, the term “active agents” refers to a pharmaceutical agent exerting a medical effect on a disease or medical condition (e.g. an amelioration thereof) and said term in particular includes the HDAC inhibitor and the CD137 agonist, such as 4SC-202 and Urelumab.

In the embodiments of the present invention, the active agents may be provided in pharmaceutical compositions comprising one or more of said active agents and a pharmaceutically acceptable carrier or diluent. In particular, the HDAC inhibitor and the CD137 agonist may be provided in separate pharmaceutical.

Such pharmaceutical compositions may be provided in the context of pharmaceutical products, comprising e.g. one or more pharmaceutical compositions and packaging material. Said packaging material typically comprises a label or package insert which indicates that the active agent(s) is/are useful for treating the diseases detailed herein. The packaging material, label and package insert otherwise parallel or resemble what is generally regarded as standard packaging material, labels and package inserts for pharmaceuticals having related utilities.

The pharmaceutical compositions according to this invention are prepared by processes which are known per se and familiar to the person skilled in the art. As pharmaceutical compositions, the active agents are either employed as such, or particularly in combination with suitable pharmaceutical auxiliaries and/or excipients, e.g. in the form of tablets, coated tablets, capsules, caplets, suppositories, patches (e.g. as TTS), emulsions, suspensions, gels or solutions, the active agent content advantageously being between 0.1 and 95% and where, by the appropriate choice of the auxiliaries and/or excipients, a pharmaceutical administration form (e.g. a delayed release form or an enteric form) exactly suited to the active agent and/or to the desired onset of action can be achieved.

The person skilled in the art is familiar with auxiliaries, vehicles, excipients, diluents, carriers or adjuvants which are suitable for the desired pharmaceutical formulations, preparations or compositions on account of his/her expert knowledge. In addition to solvents, gel formers, ointment bases and other excipients, for example antioxidants, dispersants, emulsifiers, preservatives, solubilizers, colorants, complexing agents or permeation promoters, can be used. In practicing the present invention and depending on the details, characteristics or purposes of their uses mentioned above, the active agents according to the present invention may be administered in combination therapy separately, sequentially, simultaneously or chronologically staggered (e.g. as combined unit dosage forms (in the case of the CD137 agonist being orally available, e.g. small molecules)), as separate unit dosage forms or adjacent discrete unit dosage forms, as fixed (in the case of the CD137 agonist being orally available, e.g. small molecules) or non-fixed combinations, as kit-of-parts or as admixtures (in the case of the CD137 agonist being orally available, e.g. small molecules)).

A“fixed combination” is defined as a combination wherein a first active ingredient and at least one further active ingredient are present together in one unit dosage or in a single entity (in the case of the CD137 agonist being orally available, e.g. small molecules). One example of a “fixed combination” is a pharmaceutical composition wherein the said first active ingredient and said further active ingredient are present in admixture for simultaneous administration, such as in a single formulation. Another example of a “fixed combination” is a pharmaceutical combination wherein the said first active ingredient and the said further active ingredient are present in one unit without being in admixture.

A“kit-of-parts” is defined as a combination wherein the said first active ingredient and the said further active ingredient are present in more than one unit. One example of a“kit-of-parts” is a combination wherein the said first active ingredient and the said further active ingredient are present separately. The components of the kit-of-parts may be administered separately, sequentially, simultaneously or chronologically staggered.

The first and further active ingredient of a combination or kit-of-parts according to this invention may be provided as separate formulations (i.e. independently of one another), which are subsequently brought together for simultaneous, sequential, separate or chronologically staggered use in combination therapy; or packaged and presented together as separate components of a combination pack for simultaneous, sequential, separate or chronologically staggered use in combination therapy.

The type of pharmaceutical formulation of the first and further active ingredient of a combination or kit-of-parts according to this invention can be similar, i.e. both ingredients are formulated in separate tablets or capsules, or can be different, i.e. suited for different administration forms, such as e.g. one active ingredient is formulated as tablet or capsule and the other is formulated for e.g. parenteral, in particular intravenous administration. A further aspect of the present invention is a combination comprising, in non-fixed form, the HDAC inhibitor and one or more further therapeutic agents for sequential, separate, simultaneous or chronologically staggered use in therapy in any order. Optionally said combination comprises instructions for its use in therapy.

A further aspect of the present invention is a combined preparation, such as e.g. a kit of parts, comprising a preparation of the HDAC inhibitor and a pharmaceutically acceptable carrier or diluent and one or more further therapeutic agents; and optionally instructions for simultaneous, sequential, separate or chronologically staggered use in therapy.

A further aspect of the present invention is a kit of parts comprising a dosage unit of the HDAC inhibitor, a dosage unit of one or more further therapeutic agents, and optionally instructions for simultaneous, sequential or separate use in therapy.

A further aspect of the present invention is a pharmaceutical product comprising the HDAC inhibitor, or one or more pharmaceutical compositions comprising said compounds; and one or more further therapeutic agents, or one or more pharmaceutical compositions comprising said therapeutic agents, for simultaneous, sequential or separate use in therapy. Optionally this pharmaceutical product comprises instructions for use in said therapy.

A further aspect of the present invention is a pharmaceutical composition as unitary dosage form comprising, in admixture, the HDAC inhibitor one or more further therapeutic agents and optionally a pharmacologically acceptable carrier, diluent or excipient.

A further aspect of the present invention is a commercial package comprising the HDAC inhibitor together with instructions for simultaneous, sequential or separate use with one or more further therapeutic agents.

In addition, the combination according to the present invention can be used in the pre- or post- surgical treatment.

In further addition, the combination according to the present invention can be used in combination with radiation therapy, in particular in sensitization of patients towards standard radiation therapy.

The administration of the combination according to the present invention and pharmaceutical compositions according to the invention may be performed in any of the generally accepted modes of administration available in the art. Illustrative examples of suitable modes of administration include intravenous, oral, nasal, parenteral, topical, transdermal and rectal delivery. In a particular embodiment of the present invention, the administration of the HDAC inhibitor is via oral delivery and the administration of the CD137 agonist is parenteral, in particular intravenous in the case of a biological, via oral delivery, e.g. in the case of a small molecule.

In the embodiments of the present invention, doses refer to the amount of compound with respect to the free form of said compound, i.e. the free acid or free base form of said compound. Consequently, adducts, salts, etc. of such free acid or free base form are actually to be administered in a correspondingly higher dose in order to account for the weight of the counter- ion or adduct partner. For example, in relation to 4SC-202 tosylate salt, a“dose of 100 mg 4SC- 202” relates to (rounded) 138 mg 4SC-202 tosylate salt - comprising 100 mg 4SC-202 free base and 38 mg toluenesulfonic acid (molecular weight of 4SC-202 = 447.513 g/mol; molecular weight of 4SC-202 tosylate salt = 619.711 g/mol; therefore 100 : 447.513 * 619.71 1 = 138).

Having described the invention in detail, the scope of the present invention is not limited only to those described characteristics or embodiments. As will be apparent to persons skilled in the art, modifications, analogies, variations, derivations, homologisations and adaptations to the described invention can be made on the base of art-known knowledge and/or, particularly, on the base of the disclosure (e.g. the explicit, implicit or inherent disclosure) of the present invention without departing from the spirit and scope of this invention as defined by the scope of the appended claims.

As used herein, the term including, unless specified otherwise, is to be understood to mean “including, but not limited to”.

As used herein, expressions such as “is/are administered” likewise refer to “is/are to be administered”.

As used herein, treatment of cancer may likewise refer to treatment of a subject suffering from cancer, e.g. a human subject suffering from cancer, or a cancer patient.

In the present invention, the administration of active agents may follow a certain schedule, which may include periods of daily administration of active agents and periods wherein only one of the active agents or no active agents are administered. Particularly, such a schedule consists of treatment cycles, wherein typically such treatment cycles can be repeated as often as necessary, i.e. as seen fit by the physician responsible for the treatment. Treatment cycles are particularly 12-16 day treatment cycles, 2 week treatment cycles, 17-25 day treatment cycles, 3 week treatment cycles, 24-32 day treatment cycles, 4 week treatment cycles, 30-40 day treatment cycles, 5 week treatment cycles, 37-47 day treatment cycles, or 6 week treatment cycles, more particularly 2 week, 3 week, 4 week, 5 week, or 6 week treatment cycles, even more particularly 2 week, 3 week, or 4 week treatment cycles, yet even more particularly 2 week or 3 week treatment cycles, yet even more particularly 3 week treatment cycles.

Typically, in the case of the CD137 agonist(s) being biologicals, they are administered only on day one of each treatment cycle. The treatment cycle then follows the usual administration cycle of the CD137 agonist(s), e.g. as typically applied by physicians and/or as approved by the governmental authorities. In the case of the CD137 agonist(s) being orally available, e.g. small molecules, they typically can be administered following the administration schedule of the HDAC inhibitor or continuously, or following a different pattern, e.g. a different pattern of the ones described herein for the HDAC inhibitor (e.g. the HDAC inhibitor being dosed every other day and the orally available CD137 agonist being administered daily.

In particular embodiments the treatment may involve a first treatment cycle, wherein only the HDAC inhibitor in administered, (i.e. no CD137 agonist is administered). Said first treatment cycle is then followed by the treatment with the combination of the CD137 agonist and the HDAC inhibitor as detailed herein. Said treatment cycle may otherwise (except for the administration of the CD137 agonist) be equal in duration and dosing of the HDAC inhibitor to the treatment cycle as described herein. In certain embodiments, in each treatment cycle, the HDAC inhibitor may be administered for a certain number of days, followed by a number of days wherein no HDAC inhibitor is administered. In particular embodiments, the HDAC inhibitor is administered daily for 14 days in a three-week treatment cycle, or daily for 7 days in a two-week treatment cycle, in each case followed by 7 days wherein no HDAC inhibitor is administered.

In other particular embodiments, the HDAC inhibitor is administered continuously, i.e. the daily dose is administered every day during the duration of the treatment.

In particular embodiments, Urelumab is administered on day 1 of a three-week treatment cycle, in particular in a dose of about 0.1 mg/kg. References and claims to the use of a certain compound for the manufacture of a medicament for the treatment of cancer in to be used combination with a certain second agent in their general and specific forms likewise relate to:

a) the use of said compound for the manufacture of a medicament for the treatment of cancer in combination with said second agent;

1.6. Use of animals

1.6.1. Animals

Animals were maintained in SPF health status according to the FELASA guidelines, Animal housing and experimental procedures were realized according to the French and European Regulations and NRC Guide for the Care and Use of Laboratory Animals [2, 3], Animals were individually identified with RFID transponder,

_• Each cage was labeled with a specific code.

1.6.2. Housing conditions [2, 3]

Animals were maintained in housing rooms under controlled environmental conditions:

_• Temperature: 22 ± 2°C,

_• Humidity 55 ± 10%,

Photoperiod (12h light/12h dark),

HEPA filtered air,

_• 15 air exchanges per hour with no recirculation.

Animal enclosures provided sterile and adequate space with bedding material, food and water, environmental and social enrichment (group housing): Top filter polycarbonate Eurostandard Type III or IV cages; Corn cob bedding (ref: LAB COB 12, SERLAB, France); 25 kGy Irradiated diet (Ssniff ^® Soest, Germany); Complete food for immunodeficient rodents - NM Extrudate; Complete food for immunocompetent rodents - R/M-H Extrudate; Sterile, filtrated at 0.2 pm water; Environmental enrichment (SIZZLE-dri kraft - D20004 SERLAB, France).

1.6.3. Induction of C38 tumors in animals

Thirty-five (35) female C57BL/6J mice were subcutaneously implanted into the right flank with C38 tumor fragments. When tumor volumes reached 500-1000 mm ³ , tumors were surgically excised and tumor fragments (30-50 mg) were subcutaneously implanted into the right flank of 224 female C57BL/6J mice at DO.

1.6.4. T reatment schedule

The treatment started when the tumors reached a mean volume of 100-200 mm ³ (day 10). Animals were randomized according to their individual tumor volume into groups each of 20 animals using Vivo Manager ^® software (Biosystemes, Couternon, France). A statistical test (analysis of variance, ANOVA) was performed to test for homogeneity between groups. The treatment schedule was chosen as follows:

Animals from group 1 received twice daily PO administrations of vehicle for 24 consecutive days (2Q1 Dx24). The bi-daily treatments were separated by a 12-hour period,

Animals from group 2 received twice daily PO administrations of 4SC-202 at 20 mg/kg for 24 consecutive days (2Q1 Dx24). The bi-daily treatments were separated by a 12-hour period,

Animals from group 3 received one IP injection of anti-CD137 antibody at 10 mg/kg every 3 days four times (Q3Dx4),

Animals from group 4 received one IP injection of anti-CD137 antibody at 10 mg/kg every 3 days four times (Q3Dx4) in combination with twice daily PO administrations of 4SC-202 at 20 mg/kg for 24 consecutive days (2Q1 Dx24). The bi-daily treatments were separated by a 12-hour period. The anti- CD137 antibody treatments were performed 6 hours after the 4SC-202 morning treatment,

1.6.5. Mice termination and tumor collection

Ten mice in each group were terminated at D28. The day of termination the mice treated with 4SC-202 received only the morning treatment.

1.6.6. T umor and clinical monitoring

All study data, including animal body weight measurements, tumor volume, clinical and mortality records, and treatment were scheduled and recorded on Vivo Manager ^® database (Biosystemes, Dijon, France). The viability and behavior were recorded every day. Body weights were measured twice a week. The length and width of the tumor were measured twice a week with calipers and the volume of the tumor were estimated by the formula: Tumor Volume = width ² x length / 2

The data demonstrates that the combination of 4SC-202 with a CD137 agonist (group d) results in a stronger and significant tumor control, compared with mono-therapy with either 4SC-202 (group d) or CD137 agonist (group c) alone (Fig. 1 A, box plot shown for day 27 data, includes all data points with median and 25/75 percentiles, whiskers indicate min to max, + indicates the mean value - Statistics: Kruscal-Wallis test, p=0.0027 (**) for anti-CD137, p<0.0001 (****) for combination of anti-CD137 and 4SC-202). Analysis of the individual curves for the animals in each group reveals that whereas anti-CD137 antibody alone (group c) resulted in regress of some tumors (7 of 20), the combination (group d) induced regression and remission of tumors in significantly more animals (15 of 20) (Fig. 1 B). Data past day 27 not shown.

In summary, the combination of the HDAC inhibitor 4SC-202 and a CD137 agonist unexpectedly showed significant tumor shrinkage and even remission in most test subjects, whereas each compound taken alone did not.
