LYOPHILIZED COMPOSITION COMPRISING (S)-ISOPROPYL 2-((S)-2- ACET AMIDO-3 -( 1 H-INDOL-3 -YL)PROP ANAMIDO)-6-DIAZO-5 - OXOHEXANOATE FOR SUBCUTANEOUS ADMINISTRATION AND THE USE THEREOF

BACKGROUND OF THE INVENTION

[0001] 6-Diazo-5-oxo-L-norleucine (DON) is a glutamine antagonist that exhibits promising activity in preclinical models to treat a variety of diseases such as cancer. See, e.g., Ahluwalia et al., Pharmac The. 46:243-371 (1990). But the clinical development of DON has been hampered by its dose-limiting toxicity in humans, especially in the intestinal epithelium. See, e.g., Rosenfeld and Roberts, Cancer Research 47: 1324-1328 (1981) and Lynch et al., Am J Clin Oncol (CCT) 5:541-543 (1982). Administering DON as a prodrug may help mitigate this toxicity.

IV. Optional Therapeutic Agents

[0100] In some therapeutic methods and uses of the disclosure, a Pharmaceutical Composition of the Disclosure is administered to a subject having cancer as a single agent. In other therapeutic methods and uses of the disclosure, a Pharmaceutical Composition of the Disclosure is administered to a subject having cancer in combination with one or more optional therapeutic agents. In one embodiment, a Pharmaceutical Composition of the Disclosure is administered in combination with one optional therapeutic agent. In another embodiment, a Pharmaceutical Composition of the Disclosure is administered in combination with two optional therapeutic agents. In another embodiment, a Pharmaceutical Composition of the Disclosure is administered in combination with three optional therapeutic agents. Optional therapeutic agents useful in treating cancer patients include those known in the art as well as those developed in the future.

[0101] Optional therapeutic agents are administered in an amount to provide their desired therapeutic effect. The effective dosage range for each optional therapeutic agent is known in the art, and the optional therapeutic agent is administered to an individual in need thereof within such established ranges.

[0102] A Pharmaceutical Composition of the Disclosure and the optional therapeutic agent(s) can be administered separately as multi-unit doses in any order, e.g., wherein a Pharmaceutical Composition of the Disclosure is administered before the optional therapeutic agent(s), or vice versa. One or more doses of a Pharmaceutical Composition of the Disclosure and the optional therapeutic agent(s) can be administered to the subject.

[0103] In one embodiment, the optional therapeutic agent comprises one or more immune checkpoint inhibitors. Examples of immune checkpoint inhibitors include PD- 1 inhibitors, PD-L1 inhibitors, CTLA-4 inhibitors, LAG3 inhibitors, TIM3 inhibitors, cd47 inhibitors, TIGIT inhibitors, and B7-H1 inhibitors. Thus, in one embodiment, the immune checkpoint inhibitor is selected from the group consisting of a PD-1 inhibitor, a PD-L1 inhibitor, a CTLA-4 inhibitor, a LAG3 inhibitor, a TIM3 inhibitor, and a cd47 inhibitor.

[0104] In another embodiment, the immune checkpoint inhibitor is a programmed cell death (PD-1) inhibitor. PD-1 is a T-cell coinhibitory receptor that plays a pivotal role in the ability of tumor cells to evade the host's immune system. Blockage of interactions between PD-1 and PD-L1, a ligand of PD-1, enhances immune function and mediates antitumor activity. Examples of PD-1 inhibitors include antibodies that specifically bind to PD-1. Particular anti-PD-1 antibodies include, but are not limited to nivolumab, pembrolizumab, STI-A1014, pidilzumab, and cemiplimab-rwlc. For a general discussion of the availability, methods of production, mechanism of action, and clinical studies of anti-PD-1 antibodies, see U.S. 2013/0309250, U.S. 6,808,710, U.S. 7,595,048, U.S. 8,008,449, U.S. 8,728,474, U.S. 8,779,105, U.S. 8,952,136, U.S. 8,900,587, U.S. 9,073,994, U.S. 9,084,776, and Naido et aL, British Journal of Cancer 777:2214-19 (2014).

[0105] In another embodiment, the immune checkpoint inhibitor is a PD-L1 (also known as B7-H1 or CD274) inhibitor. Examples of PD-L1 inhibitors include antibodies that specifically bind to PD-L1. Particular anti-PD-Ll antibodies include, but are not limited to, avelumab, atezolizumab, durvalumab, and BMS-936559. For a general discussion of the availability, methods of production, mechanism of action, and clinical studies, see U.S. 8,217,149, U.S. 2014/0341917, U.S. 2013/0071403, WO 2015036499, and Naido et al., British Journal of Cancer 777:2214-19 (2014).

[0106] In another embodiment, the immune checkpoint inhibitor is a CTLA-4 inhibitor. CTLA-4, also known as cytotoxic T-lymphocyte antigen 4, is a protein receptor that downregulates the immune system. CTLA-4 is characterized as a "brake" that binds costimulatory molecules on antigen-presenting cells, which prevents interaction with CD28 on T cells and also generates an overtly inhibitory signal that constrains T cell activation. Examples of CTLA-4 inhibitors include antibodies that specifically bind to CTLA-4. Particular anti-CTLA-4 antibodies include, but are not limited to, ipilimumab and tremelimumab. For a general discussion of the availability, methods of production, mechanism of action, and clinical studies, see U.S. 6,984,720, U.S. 6,207,156, and Naido et al, British Journal of Cancer 777:2214-19 (2014).

[0107] In another embodiment, the immune checkpoint inhibitor is a LAG3 inhibitor. LAG3, Lymphocyte Activation Gene 3, is a negative co-stimulatory receptor that modulates T cell homeostasis, proliferation, and activation. In addition, LAG3 has been reported to participate in regulatory T cells (Tregs) suppressive function. A large proportion of LAG3 molecules are retained in the cell close to the microtubuleorganizing center, and only induced following antigen specific T cell activation. U.S. 2014/0286935. Examples of LAG3 inhibitors include antibodies that specifically bind to LAG3. Particular anti-LAG3 antibodies include, but are not limited to, GSK2831781. For a general discussion of the availability, methods of production, mechanism of action, and studies, see, U.S. 2011/0150892, U.S. 2014/0093511, U.S. 20150259420, and Huang et aL, Immunity 21 :503-13 (2004).

[0108] In another embodiment, the immune checkpoint inhibitor is a TIM3 inhibitor. TIM3, T-cell immunoglobulin and mucin domain 3, is an immune checkpoint receptor that functions to limit the duration and magnitude of T _H 1 and T _C 1 T-cell responses. The TIM3 pathway is considered a target for anticancer immunotherapy due to its expression on dysfunctional CD8 ⁺ T cells and Tregs, which are two reported immune cell populations that constitute immunosuppression in tumor tissue. Anderson, Cancer Immunology Research 2:393-98 (2014). Examples of TIM 3 inhibitors include antibodies that specifically bind to TIM3. For a general discussion of the availability, methods of production, mechanism of action, and studies of TIM3 inhibitors, see U.S. 20150225457, U.S. 20130022623, U.S. 8,522,156, Ngiow et al., Cancer Res 71: 6567- 71 (2011), Ngiow, et al., Cancer Res 77:3540-51 (2011), and Anderson, Cancer Immunology Res 2:393-98 (2014).

[0109] In another embodiment, the immune checkpoint inhibitor is a cd47 inhibitor. See Unanue, E.R., PNAS 110: 10886-87 (2013).

[0110] In another embodiment, the immune checkpoint inhibitor is a TIGIT inhibitor. See Harjunpaa 1 and Guillerey, Clin Exp Immunol 200: 108-119 (2019).

[OHl] The one or more immune checkpoint inhibitors are administered to the subject in therapeutically effective amounts. These amounts are guided by standard clinical practice, e.g., according to the prescribing information associated with the immune checkpoint inhibitors.

[0112] For example, when the immune checkpoint inhibitor(s) is a monoclonal antibody, about 1 to about 2000 mg can be administered as an intravenous infusion every 2-4 weeks. For example, about 10 mg, about 20 mg, about 30 mg, about 40 mg, about 50 mg, about 60 mg, about 70 mg, about 80 mg, about 90 mg, about 100 mg, about 150 mg, about 200 mg, about 250 mg, about 300 mg, about 350 mg, about 400 mg, about 450 mg, about 500 mg, about 550 mg, about 600 mg, about 650 mg, about 700 mg, about 750 mg, about 800 mg, about 850 mg, about 900 mg, about 950 mg, about 1000 mg, about 1100 mg, about 1200 mg, about 1300 mg, about 1400 mg, about 1500 mg, about 1600 mg, about 1700 mg, about 1800 mg, about 1900 mg, or about 2000 mg of the antibody can be administered.

[0113] For example, when immune checkpoint inhibitor is nivolumab, 240 mg may be administered to the subject by intravenous infusion every two weeks, or 480 mg may be administered by intravenous infusion every for weeks.

[0114] For example, when the immune checkpoint inhibitors is pembrolizumab, 200 mg may be administered to the subject by intravenous infusion every three weeks, or 400 mg may be administered to the subject by intravenous infusion every six weeks.

[0115] For example, when the immune checkpoint inhibitors is avelumab, 800 mg may be administered to the subject by intravenous infusion every two weeks.

[0116] For example, when immune checkpoint inhibitors is atezolizumab, 840 mg may be administered by intravenous infusion every two weeks, or 1200 mg may be administered by intravenous infusion every three weeks, or 1680 mg may be administered by intravenous infusion every four weeks.

[0117] For example, when the immune checkpoint inhibitors is ipilumumab, 3 mg/kg may be administered to the subject by intravenous infusion every three weeks.

[0118] For example, when the immune checkpoint inhibitors is tremelimumab, 3 to 20 mg/kg may be administered to the subject by intravenous infusion every four weeks.

[0119] For example, when immune checkpoint inhibitors is GSK2831781, 1.5 to 5 mg/kg may be administered to the subject by intravenous infusion every 2-4 weeks.

[0120] Representative dosing regimens for certain immune checkpoint inhibitors to treat certain cancers are provided in Table 3.

Table 3

[0121] In one embodiment, the immune checkpoint inhibitor(s) is an antibody, and 1 to 20 mg/kg is administered to the subject by intravenous infusion every 2-4 weeks. In another embodiment, 20-2000 mg of the antibody is administered to the subject by intravenous infusion every 2-4 weeks. In another embodiment, Compound 1 is administered prior to administration of the antibody. In another embodiment, Compound 1 is administered to the subject 1, 2, 3, 4, 5, 6, or 7 days prior to the day of administration of the antibody. In another embodiment, Compound 1 is administered to the subject the day the antibody is administered. In another embodiment, Compound 1 is administered to the subject 1, 2, 3, 4, 5, 6, or 7 days after the day of administration of the antibody. [0122] For example, the subject receives pembrolizumab administered by intravenous infusion every three weeks and Compound 1 administered two times a week by subcutaneous infusion, wherein the first dose of Compound 1 is administered prior to the first dose of pembrolizumab, the first dose of Compound 1 is administered on the same day as the first dose of pembrolizumab, or the first dose of Compound 1 is administered after to the first dose of pembrolizumab, e.g., until disease progression or until there is no therapeutic benefit.

[0123] For example, the subject receives nivolumab administered by intravenous infusion every two weeks and Compound 1 administered two times a week by subcutaneous infusion, wherein the first dose of Compound 1 is administered prior to the first dose of nivolumab, the first dose of Compound 1 is administered on the same day as the first dose of nivolumab, or the first dose of Compound 1 is administered after to the first dose of nivolumab, e.g., until disease progression or until there is no therapeutic benefit.

[0124] In another embodiment, the treatment of the cancer patient with Compound 1 and one or more an immune checkpoint inhibitors induces anti-proliferative response faster than when the immune checkpoint inhibitor is administered alone.

[0125] The term "antibody" is meant to include intact monoclonal antibodies, polyclonal antibodies, multispecific antibodies formed from at least two intact antibodies, and antibody fragments, so long as they exhibit the desired biological activity. In another embodiment, "antibody" is meant to include soluble receptors that do not possess the Fc portion of the antibody. In one embodiment, the antibodies are humanized monoclonal antibodies and fragments thereof made by means of recombinant genetic engineering.

[0127] Another class of immune checkpoint inhibitors include compounds with peptide moieties that inhibit PD-1 signaling. Examples of such compounds are disclosed in U.S. Pat. 8,907,053. [0128] Another class of immune checkpoint inhibitors include inhibitors of certain metabolic enzymes, such as indoleamine 2,3 dioxygenase (IDO), which is expressed by infiltrating myeloid cells and tumor cells, and isocitrate dehydrogenase (IDH), which is mutated in leukemia cells. Mutants of the IDH enzyme lead to increased levels of 2- hydroxyglutarate (2-HG), which prevent myeloid differentiation. Stein et al., Blood 130:122-3 (2017); Wouters, Blood 730:693-94 (2017). Particular mutant IDH blocking agents include, but are not limited to, ivosidenib and enasidenib mesylate. Dalle and DiNardo, Ther Adv Hematol 9 7):163-73 (2018); Nassereddine et al., Onco Targets Ther 72:303-08 (2018). The IDO enzyme inhibits immune responses by depleting amino acids that are necessary for anabolic functions in T cells or through the synthesis of particular natural ligands for cytosolic receptors that are able to alter lymphocyte functions. Pardoll, Nature Reviews. Cancer 72:252-64 (2012); Lob, Cancer Immunol Immunother 55:153-57 (2009).

Table 5 [0164] For a more detailed description of anticancer agents and other optional therapeutic agents, those skilled in the art are referred to any number of instructive manuals including, but not limited to, the Physician's Desk Reference and to Goodman and Gilman's "Pharmaceutical Basis of Therapeutics" tenth edition, Eds. Hardman et al., 2002.

[0165] In another embodiment, the methods of treating cancer provided herein comprise administering a Pharmaceutical Composition of the Disclosure to a subject in combination with radiation therapy and, optionally, an immune checkpoint inhibitor. The methods provided herein are not limited by the types, amounts, or delivery and administration systems used to deliver the therapeutic dose of radiation to a patient. For example, the patient may receive photon radiotherapy, particle beam radiation therapy, other types of radiotherapies, and combinations thereof. In some embodiments, the radiation is delivered to the patient using a linear accelerator. In still other embodiments, the radiation is delivered using a gamma knife.

[0166] The source of radiation can be external or internal to the patient. External radiation therapy is most common and involves directing a beam of high-energy radiation to a tumor site through the skin using, for instance, a linear accelerator. While the beam of radiation is localized to the tumor site, it is nearly impossible to avoid exposure of normal, healthy tissue. However, external radiation is usually well tolerated by patients. Internal radiation therapy involves implanting a radiation-emitting source, such as beads, wires, pellets, capsules, particles, and the like, inside the body at or near the tumor site including the use of delivery systems that specifically target cancer cells (e.g., using particles attached to cancer cell binding ligands). Such implants can be removed following treatment, or left in the body inactive. Types of internal radiation therapy include, but are not limited to, brachytherapy, interstitial irradiation, intracavity irradiation, radioimmunotherapy, and the like.

[0167] The patient may optionally receive radiosensitizers (e.g., metronidazole, misonidazole, intra-arterial Budr, intravenous iododeoxyuridine (ludR), nitroimidazole, 5-substituted-4-nitroimidazoles, 2H-isoindolediones, [[(2-bromoethyl)-amino]methyl]- nitro-lH-imidazole-l-ethanol, nitroaniline derivatives, DNA-affinic hypoxia selective cytotoxins, halogenated DNA ligand, 1,2,4 benzotriazine oxides, 2-nitroimidazole derivatives, fluorine-containing nitroazole derivatives, benzamide, nicotinamide, acridine-intercalator, 5-thiotretrazole derivative, 3-nitro-l,2,4-triazole, 4,5- dinitroimidazole derivative, hydroxylated texaphrins, cisplatin, mitomycin, tiripazamine, nitrosourea, mercaptopurine, methotrexate, fluorouracil, bleomycin, vincristine, carboplatin, epirubicin, doxorubicin, cyclophosphamide, vindesine, etoposide, paclitaxel, heat (hyperthermia), and the like), radioprotectors (e.g., cysteamine, aminoalkyl dihydrogen phosphorothioates, amifostine (WR 2721), IL-1, IL-6, and the like). Radiosensitizers enhance the killing of tumor cells. Radioprotectors protect healthy tissue from the harmful effects of radiation.

[0168] Any type of radiation can be administered to a patient, so long as the dose of radiation is tolerated by the patient without unacceptable negative side-effects. Suitable types of radiotherapy include, for example, ionizing (electromagnetic) radiotherapy (e.g., X-rays or gamma rays) or particle beam radiation therapy (e.g., high linear energy radiation). Ionizing radiation is defined as radiation comprising particles or photons that have sufficient energy to produce ionization, i.e., gain or loss of electrons (as described in, for example, U.S. 5,770,581 incorporated herein by reference in its entirety). The effects of radiation can be at least partially controlled by the clinician. In one embodiment, the dose of radiation is fractionated for maximal target cell exposure and reduced toxicity.

[0169] In one embodiment, the total dose of radiation administered to a patient is about .01 Gray (Gy) to about 100 Gy. In another embodiment, about 10 Gy to about 65 Gy (e.g., about 15 Gy, 20 Gy, 25 Gy, 30 Gy, 35 Gy, 40 Gy, 45 Gy, 50 Gy, 55 Gy, or 60 Gy) are administered over the course of treatment. While in some embodiments a complete dose of radiation can be administered over the course of one day, the total dose is ideally fractionated and administered over several days. Desirably, radiotherapy is administered over the course of at least about 3 days, e.g., at least 5, 7, 10, 14, 17, 21, 25, 28, 32, 35, 38, 42, 46, 52, or 56 days (about 1-8 weeks). Accordingly, a daily dose of radiation will comprise approximately 1-5 Gy (e.g., about 1 Gy, 1.5 Gy, 1.8 Gy, 2 Gy, 2.5 Gy, 2.8 Gy, 3 Gy, 3.2 Gy, 3.5 Gy, 3.8 Gy, 4 Gy, 4.2 Gy, or 4.5 Gy), or 1-2 Gy (e.g., 1.5-2 Gy). The daily dose of radiation should be sufficient to induce destruction of the targeted cells. If stretched over a period, in one embodiment, radiation is not administered every day, thereby allowing the animal to rest and the effects of the therapy to be realized. For example, radiation desirably is administered on 5 consecutive days, and not administered on 2 days, for each week of treatment, thereby allowing 2 days of rest per week. However, radiation can be administered 1 day/week, 2 days/week, 3 days/week, 4 days/week, 5 days/week, 6 days/week, or all 7 days/week, depending on the animal's responsiveness and any potential side effects. Radiation therapy can be initiated at any time in the therapeutic period. In one embodiment, radiation is initiated in week 1 or week 2, and is administered for the remaining duration of the therapeutic period. For example, radiation is administered in weeks 1-6 or in weeks 2-6 of a therapeutic period comprising 6 weeks for treating, for instance, a solid tumor. Alternatively, radiation is administered in weeks 1-5 or weeks 2-5 of a therapeutic period comprising 5 weeks. These exemplary radiotherapy administration schedules are not intended, however, to limit the methods provided herein.

EXAMPLE 5

Subcutaneous Pharmaceutical Composition Studies

[0434] To assess the stability of the LI pharmaceutical composition (also referred to as E8h) prepared according to EXAMPLE 2 at 2-8 °C over 5 days, a study was conducted to determine the chemical and colloidal stability for two concentrations - suspension of the lyophilate with 2.5 mL WFI and 10.0 mL WFI. At each concentration, 5 vials were used. All were suspended time zero and were subsequently assayed for their properties following varying hold times. Data on the suspension (Recon) time and appearance is summarized below in Table 16. Table 16

[0435] Over the first 3 days, the vials could easily be resuspended (shaken again to achieve a uniform drug product), but on Day 5, the appearance was no longer uniform.

[0436] The particle size distribution (PSD) was measured over the course of the study, with each test vial suspended on Day 0 and held until it was resuspended and sampled at its scheduled test time. Data on the PSD is summarized in Table 17.

Table 17

[0437] The PSD is uniform through Day 3, but on Day 5 it has a shift upward. No change in impurities as measured by HPLC was seen over the 5-day study. A decrease in Compound 1 was seen on Day 5 in the 10 mL resuspension. This data is summarized in the table of percent label claim as shown in Table 18.

Table 18 [0438] Following resuspension, the accuracy of delivery of Compound 1 from the pharmaceutical composition using a 0.5 mL tuberculin syringe was tested. 150 microliters of the suspension was drawn up in the syringe and injected into a volumetric flask for assay. Repeated trials were conducted using fresh syringes in order to confirm the relative standard deviation (RSD) with HPLC assays conducted in duplicate. The data is tabulated in the tables below.
