The tumor suppressor protein p53 is a sequence specific transcription factor and plays a central role in the regulation of several cellular processes, including cell cycle and growth arrest, apoptosis, DNA repair, senescence, angiogenesis, and innate immunity. The Mouse Double Minute 2 (MDM2) protein (or its human homolog also known as HDM2) acts to down-regulate p53 activity in an auto-regulatory manner, and under normal cellular conditions (absence of stress), the MDM2 protein serves to maintain p53 activity at low levels. MDM2 directly inhibits the transactivation function of p53, exports p53 out of the nucleus, and promotes proteasome-mediated degradation of p53 through its E3 ubiquitin ligase activity.
Deregulation of the MDM2/p53 balance by overexpression of MDM2 or by p53 mutation or loss leads to malignant transformation of normal cells. Presently p53 is known to play a key role in practically all types of human cancers, and the mutation or loss of the p53 gene can be identified in more than 50% of all human cancers worldwide. Analysis of 28 different types of human cancers in nearly 4,000 human tumor samples showed that MDM2 is amplified in 7% of human cancers and that MDM2 overexpression by amplification and p53 mutations are largely mutually exclusive (Momand et al., Nucleic Acid Res (1998) 26:3453-3459).
Because of the powerful tumor suppressor function of p53, reactivation of p53 has been long sought as a potentially novel cancer therapeutic strategy. In tumor harboring wild-type p53, MDM2 is the primary cellular inhibitor of p53 activity, and overexpression of MDM2 was found in many human tumors. Since MDM2 inhibits p53 through a direct protein-protein interaction, blocking this interaction using small molecules was pursued in several academic and industrial pharmaceutical laboratories in the last decade. A variety of non-peptide, drug-like small molecule as e.g. imidazole compounds (e.g. Nutlins or RG7112), benzodiazepinedione compounds, spirooxindole compounds (e.g. MI-219), substituted piperidines, pyrrolidinone compounds (e.g. PXN820-dl) and modifications thereof have been selected and designed in order to block MDM2/p53 interaction as a means to reactivate p53 in cells (Vassilev et al., Science (2004) 303:844-848; Grasberger et al., J Med Chem (2005) 48:909-912; Parks et al., Bioorg Med Chem Lett (2005) 15:765; Ding et al., J Am Soc (2005) 127:10130-10131; WO 2010/028862, U.S. Pat. No. 7,884,107, WO 2008/119741). A number of potent MDM2/p53 inhibitors have been evaluated in animal models of human cancer for their anti-tumor activity (Vassilev et al., Science (2004) 303:844-848; Tovar et al, Cancer Res (2013) 73 (8): 2587-2597; Ding et al , Journal of Medicinal Chemistry (2013) 56 (14): 5979-5983; Rew et al, Journal of Medicinal Chemistry (2012) 55:4936-4954; Sun et al, Journal of Medicinal Chemistry (2014) 57 (4): 1454-1472).
In the pediatric preclinical testing program (PPTP) of the NCI, early evidence for high level anti-proliferative activity of RG7112, an inhibitor of the MDM2-p53 interaction, could be observed in vitro and in vivo. In particular, RG-7112 showed cytotoxic activity with lower median IC50 values for p53 wild-type vs. p53 mutant cell lines (Carol et al., Pediatric Blood and Cancer (2013) 60(4):633-641). Moreover, RG-7112 induced tumor growth inhibition in solid tumor xenograft models and was particularly efficacious in in acute lymphoblastic leukemia (ALL) xenograft models with mixed-lineage leukemia (MLL) rearrangement, (Carol et al., Pediatric Blood and Cancer (2013) 60(4):633-641). Additionally, the antiproliferative and proapoptotic activity of RG7112 has been observed in human acute myeloid leukemia (AML) and human prostate tumor xenograft models harboring p53 wild-type (Tovar et al, Cancer Res (2013) 73 (8): 2587-2597).
Cancer immunotherapy is a branch of oncology in which the immune system is used to treat cancer which is in stark contrast to existing common methods of treatment in which the tumour is directly excised or treated. This therapeutic concept is based on the identification of a number of proteins on the surface of T-cells which act to inhibit the immune function of these cells. Listed among these proteins is PD-1.
PD-1 (Programmed cell Death 1) is a cell surface receptor protein expressed on T-cells. The protein functions as an “immune checkpoint” inhibitor, i.e. it acts to modulate the activity of cells in the immune system so as to regulate and limit autoimmune diseases. It has been recently understood that many cancers can protect themselves from the immune system by modifying “immune checkpoint” inhibitors and thus avoid detection.
PD-1 has two ligands, PD-L1 and PD-L2, which interact with the cell surface receptor. On binding, PD-1 induces an intracellular signal which negatively regulates T-cell response.
As detailed above, PD-1 is a key regulator of T-cell activity. Recently, it has been shown in a range of different cancer settings that the antagonistic PD-1 antibody molecules nivolumab and pembrolizumab can be used to stimulate the immune system and thereby treat cancer.
Lymphocyte Activation Gene-3 (LAG-3; CD223) is a type I transmembrane protein mainly expressed on the cell surface of activated T cells but also found on subsets of NK and dendritic cells. LAG3 is closely related to CD4, which is a co-receptor for T helper cell activation. Both molecules have four extracellular Ig-like domains and require binding to their ligand, major histocompatibility complex (MHC) class II, for their functional activity.
On binding to MHC-II, LAG3 induces an intracellular signal which negatively regulates T-cell response. Recent studies have revealed that LAG-3 and PD-1 are co-expressed on tumor infiltrating lymphocytes (TILs) suggesting that they may contribute to tumor-mediated immune suppression. It is thought that chronic exposure to antigens leads to a progressive inactivation of T cells through a process termed “exhaustion”. Exhausted T cells often co-express negative regulatory receptors such as PD-1 and LAG-3.
Despite encouraging clinical results of PD-1 antagonistic monoclonal antibodies nivolumab and pembrolizumab, up to 70% of treated patients do not respond to treatment. Preclinical data with patient-derived T cells as well as from syngeneic tumour mouse models have demonstrated that tumour-derived T cells frequently express other inhibitory receptors in addition to PD1. Combined neutralization of PD-1 and LAG-3 using antagonistic monoclonal antibody molecules increased reactivation of T cells and improved tumour rejection compared to PD-1 neutralization alone, in in vitro and in vivo models. Based on these results, it is expected that neutralization of LAG-3 will enhance the efficacy of antagonistic PD-1 mAbs.
The efficacy of therapeutic agents can be improved by using combination therapies (in particular in oncology) with other compounds and/or improving the dosage schedule. Even if the concept of combining several therapeutic agents has already been suggested, and although various combination therapies are under investigation and in clinical trials, there is still a need for new and efficient therapeutic concepts for the treatment of cancer diseases, e.g. solid tumors, which show advantages over standard therapies, such as for example better treatment outcome, beneficial effects, superior efficacy and/or improved tolerability, such as e.g. reduced side effects of the combined treatment. Specifically, there is a need for additional treatment options for patients with cancers like, e.g., lung cancer (e.g. NSCLC), brain cancer (e.g. glioblastoma, also including brain metastasis of cancers with other origin), soft tissue sarcoma (e.g. liposarcoma) and genitourinary cancer (e.g. bladder cancer).
It is thus an object of the present invention to provide combination treatments/methods of combination treatment providing certain advantages compared to treatments/methods of treatment currently used and/or known in the prior art. These advantages may include in vivo efficacy (e.g. improved clinical response, extend of the response, increase of the rate of response, duration of response, disease stabilization rate, duration of stabilization, time to disease progression, progression free survival (PFS) and/or overall survival (OS), later occurence of resistance and the like), safe and well tolerated administration and reduced frequency and severity of adverse events.

To be used in therapy, the MDM2 inhibitor is included into pharmaceutical compositions appropriate to facilitate administration to animals or humans.
Typical pharmaceutical compositions for administering the MDM2 inhibitor of the invention include for example tablets, capsules, suppositories, solutions, e.g. solutions for injection (s.c., i.v., i.m.) and infusion, elixirs, emulsions or dispersible powders. The content of the pharmaceutically active compound(s) may be in the range from 0.1 to 90 wt.-%, preferably 40 to 60 wt.-% of the composition as a whole, e.g. in amounts which are sufficient to achieve the desired dosage range. The single dosages may, if necessary, be given several times a day to deliver the desired total daily dose.
Typical tablets may be obtained, for example, by mixing the active substance(s), optionally in combination, with known excipients, for example inert diluents such as calcium carbonate, calcium phosphate, cellulose or lactose, disintegrants such as corn starch or alginic acid or crospovidon, binders such as starch or gelatine, lubricants such as magnesium stearate or talc and/or agents for delaying release, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate. The tablets may be prepared by usual processes, such as e.g. by direct compression or roller compaction. The tablets may also comprise several layers.
Coated tablets may be prepared accordingly by coating cores produced analogously to the tablets with substances normally used for tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. To achieve delayed release or prevent incompatibilities the core may also consist of a number of layers. Similarly the tablet coating may consist of a number of layers to achieve delayed release, possibly using the excipients mentioned above for the tablets.
Syrups or elixirs containing the active substance(s) may additionally contain a sweetener such as saccharine, cyclamate, glycerol or sugar and a flavour enhancer, e.g. a flavouring such as vanillin or orange extract. They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
Solutions for injection and infusion are prepared in the usual way, e.g. with the addition of isotonic agents, preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid, optionally using emulsifiers and/or dispersants, whilst if water is used as the diluent, for example, organic solvents may optionally be used as solvating agents or dissolving aids, and transferred into injection vials or ampoules or infusion bottles.
Capsules containing the active substance(s) may for example be prepared by mixing the active substance(s) with inert carriers such as lactose or sorbitol and packing them into gelatine capsules.
Typical suppositories may be made for example by mixing the active substance(s) with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
Excipients which may be used include, for example, water, pharmaceutically acceptable organic solvents such as paraffins (e.g. petroleum fractions), vegetable oils (e.g. groundnut or sesame oil), mono- or polyfunctional alcohols (e.g. ethanol or glycerol), carriers such as e.g. natural mineral powders (e.g. kaolins, clays, talc, chalk), synthetic mineral powders (e.g. highly dispersed silicic acid and silicates), sugars (e.g. cane sugar, lactose and glucose) emulsifiers (e.g. lignin, spent sulphite liquors, methylcellulose, starch and polyvinylpyrrolidone) and lubricants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate).
The MDM2 inhibitor of this invention and all its embodiments is administered by the usual methods, preferably by oral or parenteral route, most preferably by oral route. For oral administration the tablets may contain, apart from the abovementioned carriers, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with various additives such as starch, preferably potato starch, gelatine and the like. Moreover, lubricants such as magnesium stearate, sodium lauryl sulphate and talc may be used at the same time for the tabletting process. In the case of aqueous suspensions the active substances may be combined with various flavour enhancers or colourings in addition to the excipients mentioned above.
For parenteral use, solutions of the active substances with suitable liquid carriers may be used.
The dosage for oral use for MDM2 inhibitors, in particular for MDM2 inhibitors in table 1, is from 1 mg to 2000 mg per dose (e.g. 10 mg to 1000 mg per dose; in a more preferred embodiment from 10 mg to 500 mg per dose; most preferred is from 10 mg to 100 mg per dose). All amounts given refer to the free base of the MDM2 inhibitor and may be proportionally higher if a pharmaceutically acceptable salt or other solid form is used.
In one embodiment the MDM2 inhibitor, in particular an MDM2 inhibitor in table 1, is dosed once daily (q.d.).
In one embodiment the MDM2 inhibitor, in particular an MDM2 inhibitor in table 1, is dosed on day 1 and day 8 of a 28 day-cycle.
In one embodiment the MDM2 inhibitor, in particular an MDM2 inhibitor in table 1, is dosed on day 1 of a 28 day-cycle.
In one embodiment the MDM2 inhibitor is dosed on day 1 to day 7 of a 28 day-cycle.
The dosage for intravenous use is from 1 mg to 1000 mg per hour, preferably between 5 and 500 mg per hour.
However, it may sometimes be necessary to depart from the amounts specified, depending on the body weight, the route of administration, the individual response to the drug, the nature of its formulation and the time or interval over which the drug is administered. Thus, in some cases it may be sufficient to use less than the minimum dose given above, whereas in other cases the upper limit may have to be exceeded. When administering large amounts it may be advisable to divide them up into a number of smaller doses spread over the day.

For anti-PD-1 antibodies, anti-PD-L1 antibodies and anti-LAG-3 antibodies as disclosed/defined herein the term “antibody”/“antibodies” encompasses antibodies, antibody fragments, antibody-like molecules and conjugates with any of the above. Antibodies include, but are not limited to, poly- or monoclonal, chimeric, humanized, human, mono-, bi- or multispecific antibodies. The term “antibody” shall encompass complete immunoglobulins as they are produced by lymphocytes and for example present in blood sera, monoclonal antibodies secreted by hybridoma cell lines, polypeptides produced by recombinant expression in host cells, which have the binding specificity of immunoglobulins or monoclonal antibodies, and molecules which have been derived from such immunoglobulins, monoclonal antibodies, or polypeptides by further processing while retaining their binding specificity. In particular, the term “antibody” includes complete immunoglobulins comprising two heavy chains and two light chains. In another embodiment, the term encompasses a fragment of an immunoglobulin, like Fab fragments. In another embodiment, the term “antibody” encompasses a polypeptide having one or more variable domains derived from an immunobulin, like single chain antibodies (scFv), single domain antibodies, and the like.
To be used in therapy, the respective anti-PD1, anti-PD-L1 and/or anti-LAG-3 antibody molecule is included into pharmaceutical compositions appropriate to facilitate administration to animals or humans.
For pharmaceutical use, the antibody molecules of the invention may be formulated as a pharmaceutical preparation comprising (i) at least one antibody of the invention and (ii) at least one pharmaceutically acceptable carrier, diluent, excipient, adjuvant, and/or stabilizer, and (iii) optionally one or more further pharmacologically active polypeptides and/or compounds. By “pharmaceutically acceptable” is meant that the respective material does not show any biological or otherwise undesirable effects when administered to an individual and does not interact in a deleterious manner with any of the other components of the pharmaceutical composition (such as e.g. the pharmaceutically active ingredient) in which it is contained. Specific examples can be found in standard handbooks, such as e.g. Remington's Pharmaceutical Sciences, 18th Ed., Mack Publishing Company, USA (1990). For example, the antibodies of the invention may be formulated and administered in any manner known per se for conventional antibodies and antibody fragments and other pharmaceutically active proteins. Thus, according to a further embodiment, the invention relates to a pharmaceutical composition or preparation that contains at least one antibodys of the invention and at least one pharmaceutically acceptable carrier, diluent, excipient, adjuvant and/or stabilizer, and optionally one or more further pharmacologically active substances.
Pharmaceutical preparations for parenteral administration, such as intravenous, intramuscular, subcutaneous injection or intravenous infusion may for example be sterile solutions, suspensions, dispersions, emulsions, or powders which comprise the active ingredient and which are suitable, optionally after a further dissolution or dilution step, for infusion or injection. Suitable carriers or diluents for such preparations for example include, without limitation, sterile water and pharmaceutically acceptable aqueous buffers and solutions such as physiological phosphate-buffered saline, Ringer's solutions, dextrose solution, and Hank's solution; water oils; glycerol; ethanol; glycols such as propylene glycol, as well as mineral oils, animal oils and vegetable oils, for example peanut oil, soybean oil, as well as suitable mixtures thereof.
Solutions of the antibody molecules of the invention may also contain a preservative to prevent the growth of microorganisms, such as antibacterial and antifungal agents, for example, p-hydroxybenzoates, parabens, chlorobutanol, phenol, sorbic acid, thiomersal, (alkali metal salts of) ethylenediamine tetraacetic acid, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, buffers or sodium chloride.
Optionally, emulsifiers and/or dispersants may be used. The proper fluidity can be maintained, for example, by the formation of liposomes, by the maintenance of the required particle size in the case of dispersions or by the use of surfactants. Other agents delaying absorption, for example, aluminum monostearate and gelatin, may also be added. The solutions may be filled into injection vials, ampoules, infusion bottles, and the like.
In all cases, the ultimate dosage form must be sterile, fluid and stable under the conditions of manufacture and storage. Sterile injectable solutions are prepared by incorporating the active compound in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filter sterilization. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and the freeze drying techniques, which yield a powder of the active ingredient plus any additional desired ingredient present in the previously sterile-filtered solutions.
Usually, aqueous solutions or suspensions will be preferred. Generally, suitable formulations for therapeutic proteins such as the antibodies of the invention are buffered protein solutions, such as solutions including the protein in a suitable concentration (such as from 0.001 to 400 mg/mL, preferably from 0.005 to 200 mg/mL, more preferably 0.01 to 200 mg/mL, more preferably 1.0-100 mg/mL, such as 1.0 mg/mL (i.v. administration) or 100 mg/mL (s.c. administration) and an aqueous buffer such as:
Preferred buffered protein solutions are solutions including about 0.05 mg/mL of the antibody of the invention dissolved in 25 mM phosphate buffer, pH 6.5, adjusted to isotonicity by adding 220 mM trehalose. In addition, other agents such as a detergent, e.g. 0.02% Tween-20 or Tween-80, may be included in such solutions. Formulations for subcutaneous application may include significantly higher concentrations of the antibody of the invention, such as up to 100 mg/mL or even above 100 mg/mL. However, it will be clear to the person skilled in the art that the ingredients and the amounts thereof as given above do only represent one, preferred option. Alternatives and variations thereof will be immediately apparent to the skilled person, or can easily be conceived starting from the above disclosure.
The antibody may be administered to the patient at a dose between 1 mg/kg to 20 mg/kg, by one or more separate administrations, or by continuous infusion, e.g. infusion over 1 hour. A typical treatment schedule usually involves administration of the antibody once every week to once every three weeks.
Combination Therapy
Within this invention it is to be understood that the combinations, compositions, kits, methods, uses or compounds for use according to this invention may envisage the simultaneous, concurrent, sequential, successive, alternate or separate administration of the active ingredients or components. It will be appreciated that the MDM2 inhibitor, the PD-1 antagonist and the LAG-3 antagonist can be administered formulated either dependently or independently, such as e.g. the MDM2 inhibitor, the PD-1 antagonist and the LAG-3 antagonist may be administered either as part of the same pharmaceutical composition/dosage form or, preferably, in separate pharmaceutical compositions/dosage forms or two may be provided as part of the same pharmaceutical composition/dosage form whereas the third is provided in a separate pharmaceutical compositions/dosage form.
In this context, “combination” or “combined” within the meaning of this invention includes, without being limited, a product that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed (e.g. free) combinations (including kits) and uses, such as e.g. the simultaneous, concurrent, sequential, successive, alternate or separate use of the components or ingredients. The term “fixed combination” means that the active ingredients are both administered to a patient simultaneously in the form of a single entity or dosage. The term “non-fixed combination” means that the active ingredients are both administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific time limits, wherein such administration provides therapeutically effective levels of the two compounds in the body of the patient. The latter also applies to cocktail therapy, e.g. the administration of three or more active ingredients.
The administration of the MDM2 inhibitor, PD-1 antagonist and LAG-3 antagonist may take place by co-administering the active components or ingredients, such as e.g. by administering them simultaneously or concurrently in one single or in two or three separate formulations or dosage forms. Alternatively, the administration of the MDM2 inhibitor, the PD-1 antagonist and the LAG-3 antagonist may take place by administering the active components or ingredients sequentially or in alternation, such as e.g. in two or three separate formulations or dosage forms.
For example, simultaneous administration includes administration at substantially the same time. This form of administration may also be referred to as “concomitant” administration. Concurrent administration includes administering the active agents within the same general time period, for example on the same day(s) but not necessarily at the same time. Alternate administration includes administration of one agent during a time period, for example over the course of a few days or a week, followed by administration of the other agents during a subsequent period of time, for example over the course of a few days or a week, and then repeating the pattern for one or more cycles. Sequential or successive administration includes administration of one agent during a first time period (for example over the course of a few days or a week) using one or more doses, followed by administration of the other agents during a second and third time period (for example over the course of a few days or a week) using one or more doses. An overlapping schedule may also be employed, which includes administration of the active agents on different days over the treatment period, not necessarily according to a regular sequence. Variations on these general guidelines may also be employed, e.g. according to the agents used and the condition of the subject.
The aforementioned applies accordingly if the combination setting is not a triple but a higher multiple combination approach.
The elements of the combinations of this invention may be administered (whether dependently or independently) by methods customary to the skilled person, e.g. by oral, enterical, parenteral (e.g., intramuscular, intraperitoneal, intravenous, transdermal or subcutaneous injection, or implant), nasal, vaginal, rectal, or topical routes of administration and may be formulated, alone or together, in suitable dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, excipients and/or vehicles appropriate for each route of administration.

Oncoloqical or Hyperproliferative Diseases/Cancers
The combinations, compositions, kits, uses, methods and compounds for use according to the present invention (including all embodiments) are useful for the treatment and/or prevention of oncological and hyperproliferative disorders.
In certain embodiments the combinations, compositions, kits, uses, methods and compounds for use according to the present invention (including all embodiments) are useful for the treatment of oncological and hyperproliferative disorders.
In certain embodiments, the hyperproliferative disorder is cancer.
Cancers are classified in two ways: by the type of tissue in which the cancer originates (histological type) and by primary site, or the location in the body, where the cancer first developed. The most common sites in which cancer develops include the skin, lung, breast, prostate, colon and rectum, cervix and uterus as well as the hematological compartment.
The combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) may be useful in the treatment of a variety of oncological and hyperproliferative disorders, in particular cancers, including, for example, but not limited to the following:
All cancers/tumors/carcinomas mentioned above which are characterized by their specific location/origin in the body are meant to include both the primary tumors and the metastatic tumors derived therefrom.
All cancers/tumors/carcinomas mentioned above may be further differentiated by their histopathological classification:
Epithelial cancers, e.g. squamous cell carcinoma (SCC) (carcinoma in situ, superficially invasive, verrucous carcinoma, pseudosarcoma, anaplastic, transitional cell, lymphoepithelial), adenocarcinoma (AC) (well-differentiated, mucinous, papillary, pleomorphic giant cell, ductal, small cell, signet-ring cell, spindle cell, clear cell, oat cell, colloid, adenosquamous, mucoepidermoid, adenoid cystic), mucinous cystadenocarcinoma, acinar cell carcinoma, large cell carcinoma, small cell carcinoma, neuroendocrine tumors (small cell carcinoma, paraganglioma, carcinoid); oncocytic carcinoma;
Nonepithilial cancers, e.g. sarcomas (fibrosarcoma, chondrosarcoma, rhabdomyosarcoma, leiomyosarcoma, hemangiosarcoma, giant cell sarcoma, lymphosarcoma, fibrous histiocytoma, liposarcoma, angiosarcoma, lymphangiosarcoma, neurofibrosarcoma), lymphoma, melanoma, germ cell tumors, hematological neoplasms, mixed and undifferentiated carcinomas;
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used to treat non-small cell lung cancer (NSCLC) (including for example locally advanced or metastatic NSCLC (stage IIIB/IV), NSCLC adenocarcinoma, NSCLC with squamous histology, NSCLC with non-squamous histology).
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of non-small cell lung cancer (NSCLC), in particular NSCLC adenocarcinoma.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of brain cancers, in particular glioblastoma, also including brain metastasis of cancers with other origin.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of soft tissue sarcoma, in particular liposarcoma.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of genitourinary cancer, in particular bladder cancer.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of cancer patients who are treatment naïve in respect of treatment with a checkpoint inhibitor or immunomodulator, i.e., e.g., patients who are treatment naïve in respect of treatment with a PD-1 antagonist and/or a LAG-3 antagonist or a combinaton thereof.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of cancer patients who relapsed during treatment with a checkpoint inhibitor or immunomodulator, i.e., e.g., patients who relapsed during treatment with a PD-1 antagonist and/or LAG-3 antagonist or during treatment with a combination thereof.
In a further embodiment of the invention, the combinations, compositions, kits, uses, methods and compounds for use according to the invention (including all embodiments) are used in the treatment of a cancer which has functional p53, in particular in the treatment of a cancer with wild type p53.
The therapeutic applicability of the combination therapy according to this invention may include first line, second line, third line or further lines of treatment of patients. The cancer may be metastatic, recurrent, relapsed, resistant or refractory to one or more anti-cancer treatments. Thus, the patients may be treatment naïve, or may have received one or more previous anti-cancer therapies, which have not completely cured the disease.
Patients with relapse and/or with resistance to one or more anti-cancer agents (e.g. the single components of the combination, or standard chemotherapeutics) are also amenable for combined treatment according to this invention, e.g. for second or third line treatment cycles (optionally in further combination with one or more other anti-cancer agents), e.g. as add-on combination or as replacement treatment.
Accordingly, some of the disclosed combination therapies of this invention are effective at treating subjects whose cancer has relapsed, or whose cancer has become drug resistant or multi-drug resistant, or whose cancer has failed one, two or more lines of mono- or combination therapy with one or more anti-cancer agents (e.g. the single components of the combination, or standard chemotherapeutics).
A cancer which initially responded to an anti-cancer drug can relapse and it becomes resistant to the anti-cancer drug when the anti-cancer drug is no longer effective in treating the subject with the cancer, e.g. despite the administration of increased dosages of the anti-cancer drug. Cancers that have developed resistance to two or more anti-cancer drugs are said to be multi-drug resistant.
Accordingly, in some methods of combination treatment of this invention, treatment with a combination according to this invention administered secondly or thirdly is begun if the patient has resistance or develops resistance to one or more agents administered initially or previously. The patient may receive only a single course of treatment with each agent or multiple courses with one, two or more agents.
In certain instances, combination therapy according to this invention may bence include initial or add-on combination, replacement or maintenance treatment.
The present invention is not to be limited in scope by the specific embodiments described herein. Various modifications of the invention in addition to those described herein may become apparent to those skilled in the art from the present disclosure. Such modifications are intended to fall within the scope of the appended claims.
All patent applications cited herein are hereby incorporated by reference in their entireties.
Anti-tumor activity of the exemplary MDM2 inhibitor BIA-1 as single agent or in combination with RMP1-14, a tool antibody to mouse PD-1, or in combination with RMP1-14 and C9B7W, a tool antibody to mouse LAG-3, in a subcutaneous syngeneic mouse model derived from the melanoma cell line B16-F10 in C57BL/6 mice.
The efficacy of the exemplary MDM2 inhibitor BIA-1 was tested in a s.c. cell line-derived syngeneic model of melanoma (B16-F10) as single agent and in combination with RMP1-14, a rat antibody to mouse PD-1 (BioXCell #BE0146), or in combination with RMP1-14 and C9B7W, a rat antibody to mouse LAG-3 (BioXCell #6E0174).
Syngeneic Mouse Model
C57BL/6NTac mice were used in this study. 5×104 melanoma cells per mouse were mixed with Matrigel and injected to establish a tumor. Tumor volume was measured two-three times per week using a caliper. Treatment started 3 days post cell injection on day 1 of the study and was stopped on day 32.
MDM2 inhibitor BIA-1 was administered daily per os (p.o.) and RMP1-14 or C9B7W were administered twice weekly i.p. Ten animals were used in the vehicle/isotype control-treated group.
Cells
B16-F10 cells were obtained from ATCC (CRL-6475). A master cell bank (MCB) and a working cell bank (WCB) were established. Cells were cultured in T175 tissue culture flasks at 37° C. and 5% CO2. The medium used was DMEM supplemented with 10% FCS (Gibco). Cultures were detached from the plastic surface using Trypsin-EDTA in PBS (Gibco) and were split every second or third day with a ratio of 1:4/1:10.
Mice
Mice were 7-8 week-old C57BL/6NTac purchased from Taconic, Denmark. After arrival at the animal facility, mice were allowed to adjust to ambient conditions for at least 5 days before they were used for experiments. They were housed in Macrolon® type III cages in groups of ten under standardized conditions at 21.5±1.5° C. and 55±10% humidity. Standardized irradiated diet (PROVIMI KLIBA) and autoclaved tap water were provided ad libitum. Microchips implanted subcutaneously under isoflurane anesthesia were used to identify each mouse. Cage cards showing the study number, the animal number, the compound and dose level, the administration route as well as the schedule remained with the animals throughout the study.
Administration of Test Compounds
BIA-1 was suspended in 0.5% Natrosol and administered intragastrically using a gavage needle at an application volume of 10 mL/kg per mouse once daily. The RMP1-14 antibody and the C9B7W antibody were diluted in PBS and injected intraperitoneally with a volume of 10 mL/kg per mouse twice weekly.
Monitoring Tumor Growth and Disease Progression
The tumor diameter was measured two-three times a week with a caliper. The volume of each tumor [in mm3] was calculated according to the formula “tumor volume=length*diameter2*πrr/6”. To monitor side effects of treatment, mice were inspected daily for abnormalities and body weight was determined daily. Animals were sacrificed at the end of the study. Animals with necrotic tumors or tumor sizes exceeding 1500 mm3 were sacrificed early during the study for ethical reasons.
Results
All treatment regimens were well-tolerated with reduced body weight gain but no body weight loss compared to vehicle/isotype control treated animals. Median tumor volumes were determined for each treatment group (
Briefly, BIA-1 single-agent significantly delayed tumor growth but did not lead to tumor regressions at the end of the study. Neither RMP1-14 nor C9B7W single-agent significantly delayed tumor growth or led to tumor regressions at the end of the study. Both dual combinations (BIA-1+RMP1-14 or RMP1-14+C9B7W) significantly delayed tumor growth. While the dual combination of BIA-1+RMP1-14 did not lead to tumor regressions at the end of the study, the dual combination of RMP1-14+C9B7W led to 1 out 10 tumor regressions at the end of the study. The triple combination of BIA-1+RMP1-14+C9B7W showed best efficacy with 5 out of 10 tumor regressions at the end of the study. Taken together these data show the superior efficacy of the triple combination in an anti-PD-1 single-agent non-responsive model (

Cells
Colon-26 cells were obtained from Cell lines Services (CLS 400156-914SF). A master cell bank (MCB) was established. Cells were cultured in T175 tissue culture flasks at 37° C. and 5% CO2. The medium used was RPMI-1640 supplemented with 2 mM L-Glutamine+10% FCS (Gibco). Cultures were detached from the plastic surface using Accutase® Solution (Sigma-Aldrich) and were split between two and three times a week with a ratio of 1:4/1:6.
Mice
Mice were 7-8 week-old BALB/cJBomTac purchased from Taconic, Denmark. After arrival at the animal facility, mice were allowed to adjust to ambient conditions for at least 5 days before they were used for experiments.

Briefly, BIA-1 single-agent and RMP1-14 single-agent both led to tumor regressions at the end of the study (2/10 animals each), while C9B7W single-agent did not lead to tumor regressions at the end of the study (0/10 animals). Both dual combinations (BIA.1+RMP1-14 or RMP1-14+C9B7W) were superior to any of the single-agent treatments with 5/10 and 4/10 tumor regressions, respectively. The triple combination of BIA-1+RMP1-14+C9B7W showed best efficacy with 9/10 tumor regressions. Taken together these data show the superior efficacy of the triple combination (

Briefly, BIA-1 single-agent led to tumor regressions in 4 for out 12 animals, while anti-LAG-3 single-agent did not lead to tumor regressions (0/12 animals). Efficacy of the dual combination of BIA-1+C9B7W (4/12 tumor regressions) was comparable to single-agent BIA-1 (4/12 tumor regressions) but superior to C9B7W single-agent (0/12 tumor regressions).The triple combination of BIA-1+RMP1-14+C9B7W showed best efficacy with 9 out of 12 tumor regressions. Taken together these data show the superior efficacy of the triple combination (
