Patent Application
20200262843
TG02 is a pyrimidine-based multi-kinase inhibitor that inhibits CDKs 1, 2, 5, 7, and 9 together with JAK2 and FLT3. It dose-dependently inhibits signaling pathways downstream of CDKs, JAK2 and FLT3 in cancer cells with the main targets being CDKs. TG02 is anti-proliferative in a broad range of tumor cell lines, inducing Gi cell cycle arrest and apoptosis. Primary cultures of progenitor cells derived from acute myeloid leukemia (AML) and polycythemia vera patients are very sensitive to TG02. Comparison with reference inhibitors that block only one of the main targets of TG02 demonstrate the benefit of combined CDK and JAK2/FLT3 inhibition in cell lines as well as primary cells. See Goh et al., Leukemia 26:236-43 (2012). TG02 is also known as SB1317 and by its chemical name: (16E)-14-methyl-20-oxa-5,7,14,26-tetraazatetracyclo[19.3.1.1(2,6). 1(8,12)]heptacosa-1(25), 2(26), 3,5,8(27), 9,11,16,21,23-decaene.

The second, third, and fourth therapeutic agents used in the therapeutic methods of the present disclosure are referred to as “optional therapeutic agents.” Such optional therapeutic agents useful in the treatment of cancer patients are known in the art. In one embodiment, the optional therapeutic agent combined with a TG02 polymorphic form is an anticancer agent. Optional therapeutic agents include, but are not limited to, temozolomide, daunorubicin, doxorubicin, epirubicin, idarubicin, valrubicin, cisplatin, bortezomib, carfilzomib, lenalidomide, sorafenib, regorafenib, radiotherapy, immune checkpoint inhibitors, e.g., PD-1 or PD-L1 inhibitors, e.g., anti-PD-1 or anti-PD-L1 antibodies, e.g., nivolumab, pembrolizumab, pidilizumab, STI-1110, avelumab, atezolizumab, durvalumab, and STI-1014.

A TG02 polymorphic form and the optional therapeutic agent can be administered together as a single-unit dose or separately as multi-unit doses, and in any order, e.g., wherein a TG02 polymorphic form is administered before the the optional therapeutic agent, or vice versa. One or more doses of a TG02 polymorphic form and the optional therapeutic agent can be administered to the patient.
Immune checkpoint inhibitors are therapies that blockade immune system inhibitor checkpoints. In some therapeutic methods of the disclosure, an immune checkpoint inhibitor is administered to a cancer patient in combination with a TG02 polymorphic form.
Immune checkpoints can be stimulatory or inhibitory. Blockade of inhibitory immune checkpoint activates immune system function and can be used for cancer immunotherapy. Pardoll, Nature Reviews. Cancer 12:252-64 (2012). Tumor cells turn off activated T cells when they attach to specific T-cell receptors. Immune checkpoint inhibitors prevent tumor cells from attaching to T cells, which results in T cells remaining activated. In effect, the coordinated action by cellular and soluble components combats pathogens and injuries by cancers. The modulation of immune system pathways may involve changing the expression or the functional activity of at least one component of the pathway to then modulate the response by the immune system. U.S. 2015/0250853. Examples of immune checkpoint inhibitors include PD-1 inhibitors, PD-L1 inhibitors, CTLA-4 inhibitors, LAG3 inhibitors, TIM3 inhibitors, cd47 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.
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-1014, and pidilzumab. 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. Pat. Nos. 6,808,710, 7,595,048, 8,008,449, 8,728,474, 8,779,105, 8,952,136, 8,900,587, 9,073,994, 9,084,776, and Naido et al., British Journal of Cancer 111:2214-19 (2014).
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-L1 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. Pat. No. 8,217,149, U.S. 2014/0341917, U.S. 2013/0071403, WO 2015036499, and Naido et al., British Journal of Cancer 111:2214-19 (2014).
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. Pat. Nos. 6,984,720, 6,207,156, and Naido et al., British Journal of Cancer 111:2214-19 (2014).
In another embodiment, the immune checkpoint inhibitor is a LAG3 inhibitor. LAG3, Lymphocyte Activation Gene 3, is a negative co-simulatory receptor that modulates T cell homeostatis, 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 microtubule-organizing 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).
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 TH1 and Tc1 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 TIM3 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. Pat. No. 8,522,156, 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).
In another embodiment, the immune checkpoint inhibitor is a cd47 inhibitor. See Unanue, E. R., PNAS 110:10886-87 (2013).

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.
Another class of immune checkpoint inhibitors include polypeptides that bind to and block PD-1 receptors on T-cells without triggering inhibitor signal transduction. Such peptides include B7-DC polypeptides, B7-H1 polypeptides, B7-1 polypeptides and B7-2 polypeptides, and soluble fragments thereof, as disclosed in U.S. Pat. No. 8,114,845.

or a pharmaceutically acceptable salt thereof, wherein the compound comprises at least 5 amino acids useful as therapeutic agents capable of inhibiting the PD-1 signaling pathway.
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. 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 12:252-64 (2012); Löb, Cancer Immunol Immunother 58:153-57 (2009). Particular IDO blocking agents include, but are not limited to levo-1-methyl typtophan (L-1MT) and 1-methyl-tryptophan (1MT). Qian et al., Cancer Res 69:5498-504 (2009); and Löb et al., Cancer Immunol Immunother 58:153-7 (2009).

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.
In some embodiments, methods provided herein comprise administering a TG02 polymorphic form to a cancer patient in combination with radiation therapy. 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.
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.
The patient may optionally receive radiosensitizers (e.g., metronidazole, misonidazole, intra-arterial Budr, intravenous iododeoxyuridine (IudR), nitroimidazole, 5-substituted-4-nitroimidazoles, 2H-isoindolediones, [[(2-bromoethyl)-amino]methyl]-nitro-1H-imidazole-1-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-1,2,4-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.
Any type of radiation can be administered to an 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. Pat. No. 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.
In one embodiment, the total dose of radiation administered to a patient is about 0.01 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.
In the therapeutic methods provided herein, the TG02 polymorphic form and optional therapeutic, e.g., anticancer, agent may be administered to a cancer patient under one or more of the following conditions: at different periodicities, at different durations, at different concentrations, by different administration routes, etc.
In some embodiments, the TG02 polymorphic form is administered prior to the optional therapeutic agent, e.g., 0.5, 1, 2, 3, 4, 5, 10, 12, or 18 hours, 1, 2, 3, 4, 5, or 6 days, or 1, 2, 3, or 4 weeks prior to the administration of optional therapeutic agent.
In some embodiments, the TG02 polymorphic form is administered after the optional therapeutic agent, e.g., 0.5, 1, 2, 3, 4, 5, 10, 12, or 18 hours, 1, 2, 3, 4, 5, or 6 days, or 1, 2, 3, or 4 weeks after the administration of the optional therapeutic agent.
In some embodiments, the TG02 polymorphic form and the optional therapeutic agent are administered concurrently but on different schedules, e.g., the TG02 polymorphic form is administered daily while the immune checkpoint inhibitor is administered once a week, once every two weeks, once every three weeks, or once every four weeks. In other embodiments, the TG02 polymorphic form is administered once a day while the immune checkpoint inhibitor and/or the optional therapeutic agent is administered once a week, once every two weeks, once every three weeks, or once every four weeks.
The therapeutic methods provided herein comprise administering a TG02 polymorphic form to a cancer patient in an amount which is effective to achieve its intended purpose. While individual needs vary, determination of optimal ranges of effective amounts of each component is within the skill of the art. Typically, a TG02 polymorphic form may be administered in an amount from about 1 mg/kg to about 500 mg/kg, about 1 mg/kg to about 100 mg/kg, or about 1 mg/kg to about 50 mg/kg. The dosage of a composition can be at any dosage including, but not limited to, 30-600 mg/day. Particular doses include 50, 100, 200, 250, 300, 400, 500, and 600 mg/day. In one embodiment, a TG02 polymorphic form is administered once a day on 3-7 consecutive days prior to the administration of the immune checkpoint inhibitor. In another embodiment, 250 mg/day of a TG02 polymorphic form is administered. In another embodiment, 250 mg/day of a TG02 polymorphic form is administered twice weekly. In another embodiment, TG02 polymorphic form administration continues on the day of the immune checkpoint inhibitor and continues for additional days until disease progression or until TG02 polymorphic form administration is no longer beneficial. These dosages are exemplary of the average case, but there can be individual instances in which higher or lower dosages are merited, and such are within the scope of this disclosure. In practice, the physician determines the actual dosing regimen that is most suitable for an individual patient, which can vary with the age, weight, and response of the particular patient.
The unit oral dose of the TG02 polymorphic form may comprise from about 0.01 to about 1000 mg, e.g., about 10 to about 500 mg of the TG02 polymorphic form. In one embodiment, the unit oral dose of the TG02 polymorphic form is 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, 70 mg 80 mg, 90 mg, 100 mg, 110 mg, 120 mg, 130 mg, 140 mg, 150 mg, 160 mg, 170 mg, 180 mg, 190 mg, 200 mg, 210 mg, 220 mg, 230 mg, 240 mg, 250 mg, 260 mg, 270 mg, 280 mg, 290 mg, or 300 mg. The unit dose may be administered one or more times daily, e.g., as one or more tablets or capsules.
In addition to administering the TG02 polymorphic form as a raw chemical, it may be administered as part of a pharmaceutical preparation or composition. In some embodiments, the pharmaceutical preparation or composition can include one or more pharmaceutically acceptable carriers, excipients, and/or auxiliaries. In some embodiments, the one or more carriers, excipients, and/or auxiliaries facilitate processing of the TG02 polymorphic form into a preparation or composition which can be used pharmaceutically. The preparations, particularly those preparations which can be administered orally or topically and which can be used for one type of administration, such as tablets, dragees, slow release lozenges and capsules, mouth rinses and mouth washes, gels, liquid suspensions, hair rinses, hair gels, shampoos and also preparations which can be administered rectally, such as suppositories, as well as suitable solutions for administration by intravenous infusion, injection, topically or orally, contain from about 0.01 to 99 percent, in one embodiment from about 0.25 to 75 percent of active compound(s), together with the one or more carriers, excipients, and/or auxiliaries.
The pharmaceutical compositions of provided herein may be administered to any patient which may experience the beneficial effects of the TG02 polymorphic form. Foremost among such patients are mammals, e.g., humans, although the methods and compositions provided herein are not intended to be so limited. Other patients include veterinary animals (cows, sheep, pigs, horses, dogs, cats and the like).
The pharmaceutical compositions provided herein are manufactured by means of conventional mixing, granulating, dragee-making, dissolving, or lyophilizing processes. Thus, pharmaceutical preparations for oral use can be obtained by combining the active compounds with solid excipients, optionally grinding the resulting mixture and processing the mixture of granules, after adding suitable auxiliaries, if desired or necessary, to obtain tablets or dragee cores.
The term “excipient” as used herein refers to any ingredient in a composition other than the TG02 polymorphic form. An excipient is typically an inert substance added to a composition to facilitate processing, handling, administration, etc. of the TG02 polymorphic form. Useful excipients include, but are not limited to, adjuvants, antiadherents, binders, carriers, disintegrants, fillers, flavors, colors, diluents, lubricants, glidants, preservatives, sorbents, solvents, surfactants, and sweeteners. In one embodiment, the composition comprises at least one excipient selected from the group consisting of silicified microcrystalline cellulose, hypromellose 2910, crospvidone, and magnesium stearate. In one embodiment, the composition comprises silicified microcrystalline cellulose.
Conventional pharmaceutical excipients are well known to those of skill in the art. In particular, one of skill in the art will recognize that a wide variety of pharmaceutically acceptable excipients can be used in admixture with crystalline polymorphic forms of TG02, including those listed in the Handbook of Pharmaceutical Excipients, Pharmaceutical Press 4th Ed. (2003), and Remington: The Science and Practice of Pharmacy, Lippincott Williams & Wilkins, 21st ed. (2005).
Suitable excipients are, in particular, fillers such as saccharides, for example lactose or sucrose, mannitol or sorbitol, cellulose preparations and/or calcium phosphates, for example tricalcium phosphate or calcium hydrogen phosphate, as well as binders such as starch paste, using, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, tragacanth, methyl cellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose, and/or polyvinyl pyrrolidone. If desired, disintegrating agents may be added such as the above-mentioned starches and also carboxymethyl-starch, cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof, such as sodium alginate. Auxiliaries can be suitable flow-regulating agents and lubricants. Suitable auxiliaries include, for example, silica, talc, stearic acid or salts thereof, such as magnesium stearate or calcium stearate, and/or polyethylene glycol. Dragee cores are provided with suitable coatings which, if desired, are resistant to gastric juices. For this purpose, concentrated saccharide solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, polyethylene glycol and/or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. In order to produce coatings resistant to gastric juices, solutions of suitable cellulose preparations such as acetylcellulose phthalate or hydroxypropylmethyl-cellulose phthalate, are used. Dye stuffs or pigments may be added to the tablets or dragee coatings, for example, for identification or in order to characterize combinations of active compound doses.
Other pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer such as glycerol or sorbitol. The push-fit capsules can contain the active compounds in the form of granules which may be mixed with fillers such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds are in one embodiment dissolved or suspended in suitable liquids, such as fatty oils, or liquid paraffin. In addition, stabilizers may be added.
Possible pharmaceutical preparations which can be used rectally include, for example, suppositories, which consist of a combination of one or more of the active compounds with a suppository base. Suitable suppository bases are, for example, natural or synthetic triglycerides, or paraffin hydrocarbons. In addition, it is also possible to use gelatin rectal capsules which consist of a combination of the active compounds with a base. Possible base materials include, for example, liquid triglycerides, polyethylene glycols, or paraffin hydrocarbons.
Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, for example, water-soluble salts and alkaline solutions. In addition, suspensions of the active compounds as appropriate oily injection suspensions may be administered. Suitable lipophilic solvents or vehicles include fatty oils, for example, sesame oil, or synthetic fatty acid esters, for example, ethyl oleate or triglycerides or polyethylene glycol-400. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension including, for example, sodium carboxymethyl cellulose, sorbitol, and/or dextran. Optionally, the suspension may also contain stabilizers.
Therapeutically effective amounts of the TG02 polymorphic form and/or the immune checkpoint inhibitor and/or the optional therapeutic agent formulated in accordance with standard pharmaceutical practices, are administered to a human patient in need thereof. Whether such a treatment is indicated depends on the individual case and is subject to medical assessment (diagnosis) that takes into consideration signs, symptoms, and/or malfunctions that are present, the risks of developing particular signs, symptoms and/or malfunctions, and other factors.
The TG02 polymorphic form, the immune checkpoint inhibitor and/or the optional therapeutic agent can be administered by any suitable route, for example by oral, buccal, inhalation, sublingual, rectal, vaginal, intracistemal or intrathecal through lumbar puncture, transurethral, nasal, percutaneous, i.e., transdermal, or parenteral (including intravenous, intramuscular, subcutaneous, intracoronary, intradermal, intramammary, intraperitoneal, intraarticular, intrathecal, retrobulbar, intrapulmonary injection and/or surgical implantation at a particular site) administration. Parenteral administration can be accomplished using a needle and syringe or using a high pressure technique.
Pharmaceutical compositions include those wherein the TG02 polymorphic form, the immune checkpoint inhibitor and/or the optional therapeutic agent are administered in an effective amount to achieve its intended purpose. The exact formulation, route of administration, and dosage is determined by an individual physician in view of the diagnosed condition or disease. Dosage amount and interval can be adjusted individually to provide levels of TG02, immune checkpoint inhibitor, COX-2 inhibitor, and/or optional therapeutic agent that is sufficient to maintain therapeutic effects.
Toxicity and therapeutic efficacy of TG02, the immune checkpoint inhibitor and/or the optional therapeutic agent can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the maximum tolerated dose (MTD) of a compound, which defines as the highest dose that causes no toxicity in a patient. The dose ratio between the maximum tolerated dose and therapeutic effects (e.g. inhibiting of tumor growth) is the therapeutic index. The dosage can vary within this range depending upon the dosage form employed, and the route of administration utilized. Determination of a therapeutically effective amount is well within the capability of those skilled in the art, especially in light of the detailed disclosure provided herein.
A therapeutically effective amount of the TG02 polymorphic form, immune checkpoint inhibitor and/or optional therapeutic agent required for use in therapy varies with the nature of the condition being treated, the length of time that activity is desired, and the age and the condition of the patient, and ultimately is determined by the attendant physician. For example, dosage amounts and intervals can be adjusted individually to provide plasma levels of TG02 and immune checkpoint inhibitor that are sufficient to maintain the desired therapeutic effects. The desired dose conveniently can be administered in a single dose, or as multiple doses administered at appropriate intervals, for example as one, two, three, four or more subdoses per day. Multiple doses often are desired, or required. For example, the TG02 polymorphic form and immune checkpoint inhibitor can be administered at a frequency of one dose per day; four doses delivered as one dose per day at four-day intervals (q4d×4); four doses delivered as one dose per day at three-day intervals (q3d×4); one dose delivered per day at five-day intervals (qd×5); one dose per week for three weeks (qwk3); five daily doses, with two days rest, and another five daily doses (5/2/5); or, any dose regimen determined to be appropriate for the circumstance.
The immune checkpoint inhibitor is administered in therapeutically effective amounts. When the immune checkpoint inhibitor is a monoclonal antibody, 1-20 mg/kg is administered as an intravenous infusion every 2-4 weeks. For example, 50 mg, 60 mg, 70 mg, 80 mg, 90 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 700 mg, 800 mg, 900 mg, 1000 mg, 1100 mg, 1200 mg, 1300 mg, 1400 mg, 1500 mg, 1600 mg, 1700 mg, 1800 mg, 1900 mg and 2000 mg of the antibody may be administered.
For example, when the immune checkpoint inhibitor is the anti-PD-1 antibody nivolumab, 3 mg/kg may be administered by intravenous infusion over 60 minutes every two weeks. When the immune checkpoint inhibitor is the anti-PD-1 antibody pembrolizumab, 2 mg/kg may be administered by intravenous infusion over 30 minutes every two or three weeks. When the immune checkpoint inhibitor is the anti-PD-L1 antibody avelumab, 10 mg/kg may be administered by intravenous infusion as frequently as every 2 weeks. Disis et al., J. Clin Oncol. 33 (2015) (suppl; abstr 5509). When the immune checkpoint inhibitor is the anti-PD-L1 antibody MPDL3280A, 20 mg/kg may be administered by intravenous infusion every 3 weeks. Herbst et al., Nature 515:563-80 (2014). When the immune checkpoint inhibitor is the anti-CTLA-4 antibody ipilumumab, 3 mg/kg may be administered by intravenous infusion over 90 minutes every 3 weeks. When the immune checkpoint inhibitor is the anti-CTLA-4 antibody tremelimumab, 15 mg/kg may be administered by intravenous infusion every 12 weeks. Naido et al., British Journal of Cancer 111:2214-19 (2014); Drugs R D, 10:123-32 (2010). When the immune checkpoint inhibitor is the anti-LAG3 antibody GSK2831781, 1.5 to 5 mg/kg may be administered by intravenous infusion over 120 minutes every 2-4 weeks. When the immune checkpoint inhibitor is an anti-TIM3 antibody, 1-5 mg/kg may be administered by intravenous infusion over 30-90 minutes every 2-4 weeks. When an inhibitor of indoleamine 2,3-dioxygenase (IDO) pathway is inhibitor indoximod in combination with temozolomide, 18.5 mg/kg/dose BID with an escalation to 27.7 mg/kg/dose BID of indoximod with 200 mg/m2 every 5 days of temozolomide.
In one embodiment, the immune checkpoint inhibitor is an antibody and 1-20 mg/kg is administered by intravenous infusion every 2-4 weeks. In another embodiment, 50-2000 mg of the antibody is administered by intravenous infusion every 2-4 weeks. In another embodiment, TG02 is administered prior to administration of the antibody. In another embodiment, TG02 is administered 3-7 days prior to the day of administration of the antibody. In another embodiment, TG02 is also administered the day the antibody is administered and on consecutive days thereafter until disease progression or until TG02 administration is no longer beneficial.
In one embodiment, the cancer patient has tumors with a biomarker, e.g., overexpression of MYC and/or MCL1, and receives 2 mg/kg pembrolizumab administered by intravenous infusion every three weeks and 30-600 mg of TG02 administered for 3-7 days prior to pembrolizumab administration, on the day of pembrolizumab administration, and thereafter until disease progression or until there is no therapeutic benefit.
In another embodiment, the cancer patient has tumors with a biomarker, e.g., overexpression of MYC and/or MCL1, and receives 3 mg/kg nivolumab administered by intravenous infusion every 2 weeks and 30-600 mg TG02 administered orally for 3-7 days prior to nivolumab administration, on the day of nivolumab administration, and thereafter until disease progression or until there is no therapeutic benefit.
In another embodiment, the cancer patient has tumors with a biomarker, e.g., overexpression of MYC and/or MCL1, and receives 3 mg/kg nivolumab administered by intravenous infusion every 2 weeks and 30-600 mg TG02 administered orally twice weekly prior to nivolumab administration, on the day of nivolumab administration, and thereafter until disease progression or until there is no therapeutic benefit.
In another embodiment, the treatment of the cancer patient with an immune checkpoint inhibitor and the TG02 polymorphic form induces anti-proliferative response faster than when the immune checkpoint inhibitor is administered alone.
In another embodiment, the treatment of the cancer patient with a COX-2 inhibitor and the TG02 polymorphic form induces anti-proliferative response faster than when the COX-2 inhibitor is administered alone.

The term “biomarker” as used herein refers to any biological compound, such as a gene, a protein, a fragment of a protein, a peptide, a polypeptide, a nucleic acid, etc., that can be detected and/or quantified in a cancer patient in vivo or in a biological sample obtained from a cancer patient. A biomarker can be the entire intact molecule, or it can be a portion or fragment thereof. In one embodiment, the expression level of the biomarker is measured. The expression level of the biomarker can be measured, for example, by detecting the protein or RNA, e.g., mRNA, level of the biomarker. In some embodiments, portions or fragments of biomarkers can be detected or measured, for example, by an antibody or other specific binding agent. In some embodiments, a measurable aspect of the biomarker is associated with a given state of the patient, such as a particular stage of cancer. For biomarkers that are detected at the protein or RNA level, such measurable aspects may include, for example, the presence, absence, or concentration, i.e., expression level, of the biomarker in a cancer patient, or biological sample obtained from the cancer patient. For biomarkers that are detected at the nucleic acid level, such measurable aspects may include, for example, allelic versions of the biomarker or type, rate, and/or degree of mutation of the biomarker, also referred to herein as mutation status.
For biomarkers that are detected based on expression level of protein or RNA, expression level measured between different phenotypic statuses can be considered different, for example, if the mean or median expression level of the biomarker in the different groups is calculated to be statistically significant. Common tests for statistical significance include, among others, t-test, ANOVA, Kruskal-Wallis, Wilcoxon, Mann-Whitney, Significance Analysis of Microarrays, odds ratio, etc. Biomarkers, alone or in combination, provide measures of relative likelihood that a subject belongs to one phenotypic status or another. Therefore, they are useful, inter alia, as markers for disease and as indicators that particular therapeutic treatment regimens will likely result in beneficial patient outcomes.
Biomarkers include, but are not limited, the genes listed in Table 1. In one embodiment, the measurable aspect of the biomarker is its expression status. In one embodiment, the measurable aspect of the biomarker is its mutation status.
Drosophila); translocated to, 11
In one embodiment, the biomarker is MYC. In one embodiment, the measurable aspect of MYC is its expression status. In one embodiment, the biomarker is overexpression of MYC.
Thus, in certain aspects of the disclosure, the biomarker is MYC which is differentially present in a subject of one phenotypic status, e.g., a patient having cancer, e.g., hepatocellular carcinoma (HCC), glioblastomas (GBM), lung cancer, breast cancer, head and neck cancer, prostate cancer, melanoma, or colorectal cancer, as compared with another phenotypic status, e.g., a normal undiseased subject or a patient having cancer without overexpression MYC.
In one embodiment, the biomarker is MCL1. In one embodiment, the measurable aspect of MCL1 is its expression status. In one embodiment, the biomarker is overexpression of MCL1.
A biomarker is differentially present between different phenotypic status groups if the mean or median expression or mutation levels of the biomarker is calculated to be different, i.e., higher or lower, between the groups. Thus, biomarkers provide an indication that a subject, e.g., a cancer patient, belongs to one phenotypic status or another.
Thus, in certain aspects of the disclosure, the biomarker is MCL1 which is differentially present, i.e., overexpressed, in a subject of one phenotypic status, e.g., a patient having cancer, e.g., hepatocellular carcinoma (HCC), glioblastomas (GBM), lung cancer, breast cancer, head and neck cancer, prostate cancer, melanoma, colorectal cancer, medulloblastoma, or general brain tumors, as compared with another phenotypic status, e.g., an undiseased patient or a cancer patient without overexpression MCL1.
In addition to individual biological compounds, e.g., MYC or MCL1, the term “biomarker” as used herein is meant to include groups, sets, or arrays of multiple biological compounds. For example, the combination of MYC and MCL1 may comprise a biomarker. The term “biomarker” may comprise one, two, three, four, five, six, seven, eight, nine, ten, fifteen, twenty, twenty five, thirty, or more, biological compounds.
The determination of the expression level or mutation status of a biomarker in a patient can be performed using any of the many methods known in the art. Any method known in the art for quantitating specific proteins and/or detecting MYC and/or MCL1 expression, or the expression or mutation levels of any other biomarker in a patient or a biological sample may be used in the methods of the disclosure. Examples include, but are not limited to, PCR (polymerase chain reaction), or RT-PCR, Northern blot, Western blot, ELISA (enzyme linked immunosorbent assay), RIA (radioimmunoassay), gene chip analysis of RNA expression, immunohistochemistry or immunofluorescence. See, e.g., Slagle et al. Cancer 83:1401 (1998). Certain embodiments of the disclosure include methods wherein biomarker RNA expression (transcription) is determined. Other embodiments of the disclosure include methods wherein protein expression in the biological sample is determined. See, for example, Harlow et al., Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., (1988) and Ausubel et al., Current Protocols in Molecular Biology, John Wiley & Sons, New York 3rd Edition, (1995). For northern blot or RT-PCR analysis, RNA is isolated from the tumor tissue sample using RNAse free techniques. Such techniques are commonly known in the art.
In one embodiment of the disclosure, a biological sample is obtained from the patient and cells in the biopsy are assayed for determination of biomarker expression or mutation status.
In one embodiment of the disclosure, PET imaging is used to determine biomarker expression.
In another embodiment of the disclosure, Northern blot analysis of biomarker transcription in a tumor cell sample is performed. Northern analysis is a standard method for detection and/or quantitation of mRNA levels in a sample. Initially, RNA is isolated from a sample to be assayed using Northern blot analysis. In the analysis, the RNA samples are first separated by size via electrophoresis in an agarose gel under denaturing conditions. The RNA is then transferred to a membrane, crosslinked and hybridized with a labeled probe. Typically, Northern hybridization involves polymerizing radiolabeled or nonisotopically labeled DNA, in vitro, or generation of oligonucleotides as hybridization probes. Typically, the membrane holding the RNA sample is prehybridized or blocked prior to probe hybridization to prevent the probe from coating the membrane and, thus, to reduce non-specific background signal. After hybridization, typically, unhybridized probe is removed by washing in several changes of buffer. Stringency of the wash and hybridization conditions can be designed, selected and implemented by any practitioner of ordinary skill in the art. Detection is accomplished using detectably labeled probes and a suitable detection method. Radiolabeled and non-radiolabled probes and their use are well known in the art. The presence and or relative levels of expression of the biomarker being assayed can be quantified using, for example, densitometry.
In another embodiment of the disclosure, biomarker expression and/or mutation status is determined using RT-PCR. RT-PCR allows detection of the progress of a PCR amplification of a target gene in real time. Design of the primers and probes required to detect expression and/or mutation status of a biomarker of the disclosure is within the skill of a practitioner of ordinary skill in the art. RT-PCR can be used to determine the level of RNA encoding a biomarker of the disclosure in a tumor tissue sample. In an embodiment of the disclosure, RNA from the biological sample is isolated, under RNAse free conditions, than converted to DNA by treatment with reverse transcriptase. Methods for reverse transcriptase conversion of RNA to DNA are well known in the art. A description of PCR is provided in the following references: Mullis et al., Cold Spring Harbor Symp. Quant. Biol. 51:263 (1986); EP 50,424; EP 84,796; EP 258,017; EP 237,362; EP 201,184; U.S. Pat. Nos. 4,683,202; 4,582,788; 4,683,194.
RT-PCR probes depend on the 5′-3′ nuclease activity of the DNA polymerase used for PCR to hydrolyze an oligonucleotide that is hybridized to the target amplicon (biomarker gene). RT-PCR probes are oligonucleotides that have a fluorescent reporter dye attached to the 5, end and a quencher moiety coupled to the 3′ end (or vice versa). These probes are designed to hybridize to an internal region of a PCR product. In the unhybridized state, the proximity of the fluor and the quench molecules prevents the detection of fluorescent signal from the probe. During PCR amplification, when the polymerase replicates a template on which an RT-PCR probe is bound, the 5′-3′ nuclease activity of the polymerase cleaves the probe. This decouples the fluorescent and quenching dyes and FRET no longer occurs. Thus, fluorescence increases in each cycle, in a manner proportional to the amount of probe cleavage. Fluorescence signal emitted from the reaction can be measured or followed over time using equipment which is commercially available using routine and conventional techniques.
In another embodiment of the disclosure, expression of proteins encoded by biomarkers are detected by western blot analysis. A western blot (also known as an immunoblot) is a method for protein detection in a given sample of tissue homogenate or extract. It uses gel electrophoresis to separate denatured proteins by mass. The proteins are then transferred out of the gel and onto a membrane (e.g., nitrocellulose or polyvinylidene fluoride (PVDF)), where they are detected using a primary antibody that specifically bind to the protein. The bound antibody can then detected by a secondary antibody that is conjugated with a detectable label (e.g., biotin, horseradish peroxidase or alkaline phosphatase). Detection of the secondary label signal indicates the presence of the protein.
In another embodiment of the disclosure, the expression of a protein encoded by a biomarker is detected by enzyme-linked immunosorbent assay (ELISA). In one embodiment of the disclosure, “sandwich ELISA” comprises coating a plate with a capture antibody; adding sample wherein any antigen present binds to the capture antibody; adding a detecting antibody which also binds the antigen; adding an enzyme-linked secondary antibody which binds to detecting antibody; and adding substrate which is converted by an enzyme on the secondary antibody to a detectable form. Detection of the signal from the secondary antibody indicates presence of the biomarker antigen protein.
In another embodiment of the disclosure, the expression of a biomarker is evaluated by use of a gene chip or microarray. Such techniques are within ordinary skill held in the art.

“Concurrent administration,” “administered in combination,” “simultaneous administration,” and similar phrases mean that two or more agents are administered concurrently to the subject being treated. By “concurrently,” it is meant that each agent is administered either simultaneously or sequentially in any order at different points in time. However, if not administered simultaneously, it is meant that they are administered to an individual in a sequence and sufficiently close in time so as to provide the desired therapeutic effect and act in concert. For example, a TG02 polymorphic form can be administered at the same time or sequentially in any order at different points in time as the immune checkpoint inhibitor and/or the optional therapeutic agent. The TG02 polymorphic form and the immune checkpoint inhibitor and/or the optional therapeutic agent can be administered separately, in any appropriate form and by any suitable route. When the TG02 polymorphic form and the immune checkpoint inhibitor and/or the optional therapeutic agent are not administered concurrently, it is understood that they can be administered in any order to a patient in need thereof. For example, the TG02 polymorphic form can be administered prior to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks before), concomitantly with, or subsequent to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks after) the immune checkpoint inhibitor, to an individual in need thereof.

Automated experiments were acquired using ICON-NMR configuration within Topspin software, using standard Brukerloaded experiments (1H, 13C {1H}, DEPT135). Off-line analysis was performed using ACD Spectrus Processor.
DSC data were collected on a TA Instruments Q2000 equipped with a 50 position auto-sampler. Typically, 0.5-1.5 mg of each sample, in a pin-holed aluminium pan, was heated at either 2° C./min or 10° C./min from 25° C. to 250° C. A purge of dry nitrogen at 50 ml/min was maintained over the sample. The instrument control software was Advantage for Q Series and Thermal Advantage and the data were analysed using Universal Analysis or TRIOS.
TGA data were collected on a TA Instruments Q500 TGA, equipped with a 16 position auto-sampler. Typically, 3-6 mg of each sample was loaded onto a pre-tared aluminium DSC pan and heated at 10° C./min from ambient temperature to 350° C. A nitrogen purge at 60 ml/min was maintained over the sample.
The instrument control software was Advantage for Q Series and Thermal Advantage and the data were analysed using Universal Analysis or TRIOS.
Samples were analysed on a Leica LM/DM polarised light microscope with a digital video camera for image capture. A small amount of each sample was placed on a glass slide, with or without immersion oil, and covered with a glass slip. The sample was viewed with appropriate magnification and partially polarised light, coupled to a X false-colour filter. Images were captured using StudioCapture or Image ProPlus software.
Sorption isotherms were obtained using a SMS DVS Intrinsic moisture sorption analyser, controlled by DVS Intrinsic Control software. The sample temperature was maintained at 25° C. by the instrument controls. The humidity was controlled by mixing streams of dry and wet nitrogen, with a total flow rate of 200 ml/min. The relative humidity was measured by a calibrated Rotronic probe (dynamic range of 1.0-100% RH), located near the sample. The weight change, (mass relaxation) of the sample as a function of % RH was constantly monitored by a microbalance (accuracy±0.005 mg).
Typically, 5-30 mg of sample was placed in a tared mesh stainless steel basket under ambient conditions. The sample was loaded and unloaded at 40% RH and 25° C. (typical room conditions). A moisture sorption isotherm was performed as outlined below (2 scans per complete cycle). The standard isotherm was performed at 25° C. at 10% RH intervals over a 0-90% RH range. Typically, a double cycle (4 scans) was carried out. Data analysis was carried out within Microsoft Excel using the DVS Analysis Suite.
The sample was recovered after completion of the isotherm and re-analysed by XRPD.
The water content of each sample was measured on a Metrohm 874 Oven Sample Processor at 150° C. with 851 Titrano Coulometer using Hydranal Coulomat AG oven reagent and nitrogen purge. Weighed solid samples were introduced into a sealed sample vial. Approximately 10 mg of sample was used per titration and duplicate determinations were made. An average of these results is presented unless otherwise stated. Data collection and analysis were performed using Tiamo software.
Aqueous solubility was determined by suspending sufficient compound in relevant media to give a maximum final concentration of ≥10 mg/ml of the parent freeform of the compound. The suspension was equilibrated at 25° C., on a Heidolph plate shaker set to 750 rpm for 24 hours. The pH of the saturated solution was then measured and the suspension filtered through a glass fibre C filter (particle retention 1.2 μm) and diluted appropriately. Quantitation was by HPLC with reference to a standard solution of approximately 0.15 mg/ml in DMSO. Different volumes of the standard, diluted and undiluted sample solutions were injected. The solubility was calculated using the peak areas determined by integration of the peak found at the same retention time as the principal peak in the standard injection.
Solid and liquid samples were exposed to accelerated stress conditions using an Atlas CPS+ light box. Samples were prepared for analysis in duplicate in clear glass vials with closed lids for the liquid samples and open vials for the solid samples. Two of the vials were exposed to light conditions and the other vial was wrapped in aluminium foil to act as reference material. The sample thickness of solid samples was no more than ˜3 mm.
Exposure to light was effected by a combination of a single quartz glass filter with two window glass filters to reduce the effects of UV light upon the test samples. Temperature effects on the samples were reduced by attaching a chiller unit to the light box. Analysis of the samples was performed by HPLC

Preparation: Method A: A 12.2% w/v solution of TG02 free base was prepared in DMSO/ethanol (94/6 v/v) by heating to about 70° C. to dissolve the TG02 free base. A separate solution of citric acid in ethanol (10% w/v) containing a 2% molar excess of citric acid relative to TG02 free base was prepared. The volume of the citric acid/ethanol solution was about 64% relative to the TG02 free base solution. The citric acid/ethanol solution (at about 70° C.) was transferred to the TG02 free base solution to form TG02 citrate, and the solution was stirred for at least 30 minutes. Warm ethanol (1.5 volume equivalents to previous citric acid/TG02 free base solution) was added and the solution was stirred for at least one hour at about 70° C. The solution was cooled to about 5° C. TG02 citrate crystallized upon cooling. TG02 citrate was collected by filtration, washed with ethanol and dried to give TG02 Form X (citrate) in 88-93% yield.
Method B: A homogeneous mixture of TG02 Form X (citrate), TG02 Citrate Pattern 1 of U.S. Pat. No. 9,120,815, and TG02 Citrate Pattern 2 of U.S. Pat. No. 9,120,815 was treated with solvent (20 vol.) and agitated for 4 days at different temperatures (5° C., 25° C., and 50° C.). The recovered solids were air dried and analysed by XRPD. As summarized in Table 11, several solvents resulted in the recovery of TG02 Form X (citrate).
1See Example 4 for discussion of Pattern 2
Characterization: Form X (citrate) is a non-solvated, non-hygroscopic crystalline form of TG02 citrate which remained unchanged by XRPD following storage at elevated temperatures and relative humidity levels (40° C./75% RH, 25° C./97% RH and 60° C./ambient RH) after 28 days. Proton NMR was consistent with the proposed structure. However, as the methylene protons of the citric acid overlapped with the D6-DMSO reference peak, the stoichiometric equivalence of citrate acid is slightly offset. Thermal gravimetric analysis revealed the sample lost 29.8% w/w between 190-230° C., possibly due to the dissociation of the salt. Differential scanning calorimetry thermal events included a single broad endotherm at 204.5° C. (366.9 J/g). Analysis of the thermal events monitored at two different heating rates (2° C. and 10° C.) revealed a significant change in both melt temperature and enthalpy (192.1° C., 336.2 J/g and 205.3° C., 378.2 J/g). This finding suggests the observed endotherm is not a pure melt (thermodynamic) but also consists of a kinetic component possibly the dissociation of the citrate. HPLC purity analysis resulted in a purity reading of 97.6%. GVS analysis showed the material to be non-hygroscopic, with an uptake of 0.13% between 0-90% RH, with a maximum difference of 0.04% hysteresis between 40-60% RH. The sample remained unchanged by XRPD following GVS analysis. Thermodynamic solubility determination produced a reading of 0.64 mg/ml solubility in aqueous media.

TG02 Citrate Pattern 1 (“Pattern 1”) of U.S. Pat. No. 9,120,815 is a non-solvated, slightly hygroscopic crystalline form of TG02 citrate, which remained unchanged by XRPD following storage at elevated temperatures and relative humidity (40° C./75% RH, 25° C./97% RH and 60° C./ambient RH) for 28 days. Proton NMR analysis was consistent with the proposed structure, although there was overlap of the methylene protons of the citrate and the D6-DMSO reference peak. Thermal gravimetric analysis showed a weight loss of 29.6% w/w between 180-240° C., possibly due to loss of citrate. Differential scanning calorimetry revealed a single endothermic event at 196.6° C. (327.7 J/g). Comparing DSC profiles of the material at two different heating rates (2° C. and 10° C.) showed a large difference in onset temperature and enthalpy. This observation suggest the endotherm is likely due to both melt of the material (thermodynamic) and loss of the citrate (kinetic). HPLC purity analysis resulted in a purity reading of 97.7%. GVS analysis showed the material to be slightly-hygroscopic, with an uptake of 1.0% between 0-90% RH and a maximum hysteresis of 0.2% between 40-50% RH. The sample remained unchanged by XRPD following GVS analysis. Thermodynamic solubility determination produced a reading of 0.33 mg/ml solubility in aqueous media. XRPD following thermodynamic solubility analysis revealed a form change from TG02 Citrate Pattern 1 to TG02 Citrate Pattern 2 (both of U.S. Pat. No. 9,120,815). The XRPD of Pattern 1 is shown in
TG02 Citrate Pattern 2 (“Pattern 2”) of U.S. Pat. No. 9,120,815 defined as a hydrated, hygroscopic crystalline form of TG02 citrate, which remained unchanged by XRPD following storage at elevated temperatures and relative humidity (40° C./75% RH and 25° C./97% RH) for 28 days. However, storage at 60° C./ambient RH resulted in additional peaks being present in the XRPD diffractogram after 7 days. These additional peaks remained throughout the 28 days storage period. This may be caused by dehydration of the hydrate. Proton NMR analysis was consistent with the proposed structure, although there was overlap of the methylene protons of the citrate and the D6-DMSO reference peak. Thermal gravimetric analysis showed two weight losses: a weight loss of 3.1% w/w between 25-115° C., possibly due to loss of water, followed by a weight loss of 29.5% w/w between 180-240° C., possibly due to the dissociation of citrate. Differential scanning calorimetry consisted of a broad, asymmetrical endotherm between 25-115° C. (70.2 J/g) followed by a large endotherm at 186.0° C. (313.4 J/g), possibly due to the sample melt and dissolution of the salt. HPLC purity analysis resulted in a purity reading of 97.7%. GVS analysis showed the material to be hygroscopic, with an uptake of 3.84% between 0-90% RH, with a maximum hysteresis of 1.4% between 10-30% RH. The sample remained unchanged by XRPD following GVS analysis. Water content was determined by Karl Fischer analysis to be 3.3%, equating to 1 molar equivalent of water. Thermodynamic solubility determination produced a reading of 0.23 mg/ml solubility in aqueous media and remained unchanged by XRPD. The XRPD of Pattern 2 is shown in
The photostability of Pattern 1 and Pattern 2 of U.S. Pat. No. 9,120,815, and Form X (citrate) was investigated to determine whether light exposure results in substance changes.
A thin layer (≤3 mm) of Pattern 1, Pattern 2, and Form X (citrate) was placed in a clear glass HPLC vial. These samples were prepared in duplicate; one set to be kept in the dark (wrapped in aluminium foil) and the other exposed to light. Images of the HPLC vials were taken before and after light exposure. Samples were exposed to irradiation (765 W/m2) for 6.9 h, equating to one weeks Miami sunshine.
No visual change in appearance, XRPD, or purity of each sample was noted.
Compatibility experiments were conducted to select excipients for TG02 Form X (citrate) for use in gelatin capsules. Binary mixtures (1:1) of an excipient and TG02 Form X (citrate) were prepared, mixed, and stored at 40°/75% RH in open and closed containers for four weeks. Blend appearance and HPLC test results (chromatographic purity and assay) obtained after four weeks of storage in both open and closed configurations were compared to the initial results (Table 13 and Table 14). No significant appearance changes were noted over the course of the study. The list of compatible and incompatible excipients is provided in Table 15.
Representative TG02 Form X (citrate) formulation compositions are provided in Table 16. The capsules are an immediate release dosage form provided in two strengths: 50 mg and 150 mg. The capsule fill is a dry powder formulated blend of TG02 Form X (citrate) and excipients. The labelled strength of the TG02 Form X (citrate) capsules is in terms of TG02 base, while the batch formula is in terms of the TG02 Form X (citrate) salt. For example, the 50 mg strength of TG02 Form X (citrate) capsules contains about 76 mg of TG02 Form X (citrate) to account for the citric acid content of the drug substance total mass. Additional compositions are provided in Table 17.
