Description

[Background technology]

[0001] Background of the Invention 6-diazo-5-oxo-L-norleucine (DON) is a glutamine antagonist that has shown promising activity in preclinical models for treating a variety of diseases, such as cancer. See, for example, Ahluwalia et al., Pharmac The. 46:243-371 (1990) (Non-Patent Literature 1). However, the clinical development of DON has been hindered by dose-limiting toxicity in humans, specifically in the intestinal epithelium. See, for example, Rosenfeld and Roberts, Cancer Research 41:1324-1328 (1981) (Non-Patent Literature 2), and Lynch et al., Am J Clin Oncol (CCT) 5:541-543 (1982) (Non-Patent Literature 3). Administering DON as a prodrug can help mitigate this toxicity.

[0083] (Table 1) TIFF0007846686000002.tif165165TIFF0007846686000003.tif220165TIFF0007846686000004.tif110165

[0084] In another embodiment, cancer is any one or more of the cancers listed in Table 2.

[0085] (Table 2) TIFF0007846686000005.tif87148

[0086] In another aspect, cancer is selected from the group consisting of head and neck squamous cell carcinoma (SCCHN), esophageal adenocarcinoma squamous cell carcinoma, gastric adenocarcinoma, colon adenocarcinoma, hepatocellular carcinoma, biliary tract cholangiocarcinoma, gallbladder adenocarcinoma, pancreatic adenocarcinoma, intraductal carcinoma in situ, breast adenocarcinoma, lung adenocarcinoma, lung squamous cell carcinoma, bladder transitional cell carcinoma, bladder squamous cell carcinoma, cervical squamous cell carcinoma, cervical adenocarcinoma, endometrial carcinoma, penile squamous cell carcinoma, and cutaneous squamous cell carcinoma.

[0091] IV. Optional therapeutic agents In some therapeutic methods and uses of the Disclosure, the pharmaceutical compositions of the Disclosure are administered as single agents to subjects with cancer. In other therapeutic methods and uses of the Disclosure, the pharmaceutical compositions of the Disclosure are administered to subjects with cancer in combination with one or more optional therapeutic agents. In one embodiment, the pharmaceutical compositions of the Disclosure are administered in combination with one optional therapeutic agent. In another embodiment, the pharmaceutical compositions of the Disclosure are administered in combination with two optional therapeutic agents. In another embodiment, the pharmaceutical compositions of the Disclosure are administered in combination with three optional therapeutic agents. Optional therapeutic agents useful in the treatment of cancer patients include those known in the Art and those to be developed in the future.

[0092] The optional therapeutic agent is administered in an amount that provides the 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 the individual in need within such established ranges.

[0093] The pharmaceutical compositions and optional therapeutic agents of this disclosure may be administered separately as multi-unit doses in any order, for example, before or after the optional therapeutic agent. The pharmaceutical compositions and optional therapeutic agents of this disclosure may be administered to a subject once or more times.

[0094] In one embodiment, an 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 PD-1 inhibitors, PD-L1 inhibitors, CTLA-4 inhibitors, LAG3 inhibitors, TIM3 inhibitors, and cd47 inhibitors.

[0095] In another embodiment, immune checkpoint inhibitors are programmed cell death (PD-1) inhibitors. PD-1 is a T-cell co-inhibitory receptor that plays a crucial role in the ability of tumor cells to evade the host immune system. Blocking the interaction between PD-1 and its ligand, PD-L1, enhances immune function and mediates antitumor activity. Examples of PD-1 inhibitors include antibodies that specifically bind to PD-1. Specific anti-PD-1 antibodies include, but are not limited to, nivolumab, pembrolizumab, STI-A1014, pidilzumab, and semiprimab-rwlc. For general considerations regarding the availability, production methods, mechanism of action, and clinical research of anti-PD-1 antibodies, please refer to US2013 / 0309250, US6,808,710, US7,595,048, US8,008,449, US8,728,474, US8,779,105, US8,952,136, US8,900,587, US9,073,994, US9,084,776, and Naido et al., British Journal of Cancer 111:2214-19 (2014).

[0096] In another embodiment, immune checkpoint inhibitors are inhibitors of PD-L1 (also known as B7-H1 or CD274). Examples of PD-L1 inhibitors include antibodies that specifically bind to PD-L1. Specific anti-PD-L1 antibodies include, but are not limited to, avelumab, atezolizumab, durvalumab, and BMS-936559. For a general discussion of availability, methods of preparation, mechanisms of action, and clinical studies, see US8,217,149, US2014 / 0341917, US2013 / 0071403, WO 2015036499, and Naido et al., British Journal of Cancer 111:2214-19 (2014).

[0097] In another aspect, immune checkpoint inhibitors are CTLA-4 inhibitors. 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 prevents interaction with CD28 on T cells by binding to costimulatory molecules on antigen-presenting cells, and also generates an explicitly inhibitory signal that restricts T cell activation. Examples of CTLA-4 inhibitors include antibodies that specifically bind to CTLA-4. Specific anti-CTLA-4 antibodies include, but are not limited to, ipilimumab and tremelimumab. For general considerations of availability, preparation methods, mechanisms of action, and clinical studies, see US6,984,720, US6,207,156, and Naido et al., British Journal of Cancer 111:2214-19 (2014).

[0098] In another embodiment, immune checkpoint inhibitors are LAG3 inhibitors. LAG3, lymphocyte activator gene 3, is a negative costimulatory receptor that modulates T cell homeostasis, proliferation, and activation. Furthermore, LAG3 has been reported to be involved in the suppressive function of regulatory T cells (Tregs). A large proportion of LAG3 molecules are retained near the intracellular microtubule-forming center and are induced only after antigen-specific T cell activation. US2014 / 0286935. Examples of LAG3 inhibitors include antibodies that specifically bind to LAG3. Specific anti-LAG3 antibodies include, but are not limited to, GSK2831781. For information on availability, preparation methods, mechanism of action, and general considerations for research, see US2011 / 0150892, US2014 / 0093511, US20150259420, and Huang et al., Immunity 21:503-13 (2004).

[0099] In another aspect, immune checkpoint inhibitors are TIM3 inhibitors. TIM3, T-cell immunoglobulin and mucin domain 3, is a T H 1 and T C 1. An immune checkpoint receptor that functions to limit the duration and magnitude of the T cell response. The TIM3 pathway consists of two reported immune cell populations that constitute immunosuppression in tumor tissue: dysfunctional CD8 +Because it is expressed in T cells and Tregs, it is considered a target for anti-cancer immunotherapy. Anderson, Cancer Immunology Research 2:393-98 (2014). Examples of TIM3 inhibitors include antibodies that specifically bind to TIM3. For general considerations regarding the availability, preparation, mechanism of action, and research of TIM3 inhibitors, see US20150225457, US20130022623, US8,522,156, Ngiow et al., Cancer Res 71:6567-71 (2011), Ngiow, et al., Cancer Res 71:3540-51 (2011), and Anderson, Cancer Immunology Res 2:393-98 (2014).

[0100] In another embodiment, immune checkpoint inhibitors are cd47 inhibitors. See Unanue, PNAS 110:10886-87 (2013).

[0101] In another embodiment, immune checkpoint inhibitors are TIGIT inhibitors. See Harjunpaa 1 and Guillerey, Clin Exp Immunol 200:108-119 (2019).

[0102] One or more immune checkpoint inhibitors in therapeutically effective doses are administered to the subject. These doses are determined by standard clinical practice, for example, according to prescribing information related to immune checkpoint inhibitors.

[0103] For example, if the immune checkpoint inhibitor is a monoclonal antibody, approximately 1 to 2000 mg may be administered intravenously every 2 to 4 weeks. For example, approximately 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, 70 mg, 80 mg, 90 mg, 100 mg, 150 mg, 200 mg, 250 mg, 300 mg, 350 mg, 400 mg, 450 mg, 500 mg, 550 mg, 600 mg, 650 mg, 700 mg, 750 mg, 800 mg, 850 mg, 900 mg, 950 mg, 1000 mg, 1100 mg, 1200 mg, 1300 mg, 1400 mg, 1500 mg, 1600 mg, 1700 mg, 1800 mg, 1900 mg, or 2000 mg of antibodies may be administered.

[0104] For example, if the 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 four weeks.

[0105] For example, if the immune checkpoint inhibitor 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.

[0106] For example, if the immune checkpoint inhibitor is avelumab, 800 mg may be administered to the patient intravenously every two weeks.

[0107] For example, if the immune checkpoint inhibitor is atezolizumab, 840 mg may be administered intravenously every two weeks, or 1200 mg may be administered intravenously every three weeks, or 1680 mg may be administered intravenously every four weeks.

[0108] For example, if the immune checkpoint inhibitor is ipilumumab, 3 mg / kg may be administered to the subject by intravenous infusion every three weeks.

[0109] For example, if the immune checkpoint inhibitor is tremelimumab, 3-20 mg / kg may be administered to the patient intravenously every four weeks.

[0110] For example, if the immune checkpoint inhibitor is GSK2831781, 1.5–5 mg / kg may be administered to the subject by intravenous infusion every 2–4 weeks.

[0111] Table 3 provides typical drug regimens for certain immune checkpoint inhibitors used to treat certain types of cancer.

[0112] (Table 3) TIFF0007846686000006.tif199156

[0113] In one embodiment, the immune checkpoint inhibitor is an antibody, administered to the subject by intravenous infusion at a dose of 1-20 mg / kg 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 before the administration of the antibody. In another embodiment, compound 1 is administered to the subject 1, 2, 3, 4, 5, 6, or 7 days before the antibody administration date. In another embodiment, compound 1 is administered to the subject on 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 antibody administration date.

[0114] For example, a patient receives pembrolizumab administered intravenously every three weeks until disease progression or until the therapeutic benefit ceases, and compound 1 administered subcutaneously twice a week, with the first dose of compound 1 administered before the first dose of pembrolizumab, on the same day as the first dose of pembrolizumab, or after the first dose of pembrolizumab.

[0115] For example, a patient receives nivolumab administered intravenously every two weeks until disease progression or until the therapeutic benefit ceases, and compound 1 administered subcutaneously twice a week, with the first dose of compound 1 administered before the first dose of nivolumab, on the same day as the first dose of nivolumab, or after the first dose of compound 1.

[0116] In another embodiment, treatment of cancer patients with compound 1 and one or more immune checkpoint inhibitors induces an antiproliferative response more quickly than when the immune checkpoint inhibitors are administered alone.

[0117] The term "antibody" includes complete monoclonal antibodies, polyclonal antibodies, multispecific antibodies formed from at least two complete antibodies, and antibody fragments, insofar as they exhibit the desired biological activity. In another embodiment, "antibody" includes soluble receptors that do not possess the Fc portion of an antibody. In one embodiment, the antibody is a humanized monoclonal antibody and its fragments produced by recombinant genetic engineering.

[0118] Another class of immune checkpoint inhibitors includes polypeptides that bind to and block the PD-1 receptor on T cells without inducing inhibitory signaling. Such peptides include B7-DC polypeptide, B7-H1 polypeptide, B7-1 polypeptide, and B7-2 polypeptide, as disclosed in U.S. Patent No. 8,114,845, as well as their soluble fragments.

[0119] Another class of immune checkpoint inhibitors includes compounds containing a peptide moiety that inhibits PD-1 signaling. Examples of such compounds are disclosed in U.S. Patent No. 8,907,053.

[0120] Another class of immune checkpoint inhibitors includes inhibitors of certain metabolic enzymes, such as indoleamine 2,3-dioxygenase (IDO), expressed by invasive myeloid and tumor cells, and isocitrate dehydrogenase (IDH), which is mutated in leukemia cells. Mutations of the IDH enzyme result in increased levels of 2-hydroxyglutaric acid (2-HG), which prevents myeloid differentiation. Stein et al., Blood 130:722-31 (2017); Wouters, Blood 130:693-94 (2017). Specific mutant IDH inhibitors include, but are not limited to, ivosidenib and enasidenib mesylate. Dalle and DiNardo, Ther Adv Hematol 9(7):163-73 (2018); Nascereddine et al., Onco Targets Ther 12:303-08 (2018). IDO enzymes inhibit the immune response by depleting amino acids necessary for anabolism in T cells, or by synthesizing specific native ligands for cytosolic receptors that can alter lymphocyte function. Pardoll, Nature Reviews. Cancer 12:252-64 (2012); Lob, Cancer Immunol Immunother 58:153-57 (2009). Specific IDO inhibitors include, but are not limited to, levo-1-methyltryptophan (L-1MT) and 1-methyltryptophan (1MT). Qian et al., Cancer Res 69:5498-504 (2009); and Lob et al., Cancer Immunol Immunother 58:153-7 (2009).

[0157] For a more detailed description of anticancer drugs and other optional therapeutic agents, those skilled in the art should consult numerous reference books, including, but not limited to, the Physician's Desk Reference and Goodman and Gilman's "Pharmaceutical Basis of Therapeutics," 10th edition, Eds. Hardman et al., 2002.

[0158] In another embodiment, a method for treating cancer provided herein includes the step of administering the pharmaceutical compositions of this disclosure to a subject in combination with radiotherapy and, optionally, an immune checkpoint inhibitor. The methods provided herein are not limited by the type, quantity, or delivery and administration system used to deliver a therapeutic dose of radiation to a patient. For example, a patient may receive photon radiotherapy, particle beam irradiation therapy, other types of radiotherapy, and combinations thereof. In some embodiments, radiation is delivered to the patient using a linear accelerator. In yet another embodiment, radiation is delivered using a gamma knife.

[0159] The radiation source may be external to or internal to the patient. External radiation therapy is the most common and involves, for example, using a linear accelerator to direct a beam of high-energy radiation through the skin to the tumor site. Although 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 the patient. Internal radiation therapy involves implanting a radiation source, such as beads, wires, pellets, capsules, or particles, into or near the tumor site in the body, for example, using a delivery system that specifically targets cancer cells (e.g., using particles attached to cancer cell-binding ligands). Such implants may be removed after the procedure or may remain in the body in an inactive state. Types of internal radiation therapy include, but are not limited to, brachytherapy, interstitial irradiation, brachytherapy, and radioimmunotherapy.

[0160] The patient may optionally use radiosensitizers (e.g., metronidazole, misonidazole, intra-arterial Budr, intravenous iododeoxyuridine (IudR), nitroimidazole, 5-substituted-4-nitroimidazole, 2H-isoindoledione, [[(2-bromoethyl)-amino]methyl]-nitro-1H-imidazole-1-ethanol, nitroaniline derivatives, DNA-affinic hypoxia-selective cytotoxins, halogenated DNA ligands, 1,2,4-benzotriazine oxide, 2-nitroimidazole derivatives, fluorine-containing nitroazole derivatives, benzamide, nicotinamide, acudiline intercalator, 5-thiotretrazole derivatives, 3-nitro-1,2,4-triazole, 4,5-dinitroimidazole derivatives, hydroxylated texafrin). Therapies may accept texaphrins, cisplatin, mitomycin, tiripazamine, nitrosourea, mercaptopurine, methotrexate, fluorouracil, bleomycin, vincristine, carboplatin, epirubicin, doxorubicin, cyclophosphamide, vindesine, etoposide, paclitaxel, heat (hyperthermia), etc.), and radioprotective agents (e.g., cysteamine, aminoalkyl dihydrogen phosphorothioate, amiphostine (WR 2721), IL-1, IL-6, etc.). Radiosensitizers enhance tumor cell death. Radioprotective agents protect healthy tissue from the harmful effects of radiation.

[0161] Any type of radiation may be administered to a patient, provided that the radiation dose is tolerable to the patient and does not have unacceptable negative side effects. Appropriate types of radiation therapy include, for example, ionizing (electromagnetic) radiation therapy (e.g., X-rays or gamma rays) or particle beam radiation therapy (e.g., high-energy radiation). Ionizing radiation is defined as radiation containing particles or photons that have sufficient energy to cause ionization, i.e., the acquisition or loss of electrons (as described, for example, in U.S. Patent No. 5,770,581, which is incorporated herein by reference in whole). The effects of radiation can be adjusted, at least in part, by a physician. In one embodiment, the radiation dose is divided so that target cell exposure is maximized and toxicity is reduced.

[0162] In one embodiment, the total dose of radiation administered to the patient is approximately 0.01 Gray (Gy) to approximately 100 Gy. In another embodiment, approximately 10 Gy to approximately 65 Gy (e.g., approximately 15 Gy, 20 Gy, 25 Gy, 30 Gy, 35 Gy, 40 Gy, 45 Gy, 50 Gy, 55 Gy, or 60 Gy) is administered during the course of treatment. In some embodiments, the total dose of radiation may be administered in one day, but ideally, the total dose is divided and administered over several days. Preferably, the radiation therapy is administered over at least approximately 3 days, for example, at least 5, 7, 10, 14, 17, 21, 25, 28, 32, 35, 38, 42, 46, 52, or 56 days (approximately 1 to 8 weeks). Therefore, the daily dose of radiation includes 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 must be sufficient to induce the destruction of target cells. In one embodiment, if the treatment is extended over a period of time, radiation is not administered daily, thereby allowing rest for the animals and enabling the therapeutic effect to be realized. For example, radiation may preferably be administered for 5 consecutive days and 2 days without administration each week of treatment, thereby allowing 2 days of rest per week. However, depending on the animal's response and any possible side effects, radiation may be administered at intervals of 1 day / week, 2 days / week, 3 days / week, 4 days / week, 5 days / week, 6 days / week, or a total of 7 days / week. Radiation therapy may be initiated at any point during the treatment period. In one embodiment, radiation may be initiated in the first or second week and administered for the remainder of the treatment period. For example, radiation may be administered in weeks 1-6 or 2-6 of a treatment period including 6 weeks to treat, for example, a solid tumor. Alternatively, radiation may be administered in weeks 1-5 or 2-5 of a treatment period including 5 weeks. However, these exemplary radiation therapy administration schedules are not intended to limit the methods provided herein.
