The present disclosure relates in general to 5-hydroxy-2-methylnaphthalene-1,4-dione. Specifically, the present disclosure relates to pharmaceutical compositions containing 5-hydroxy-2-methylnaphthalene-1,4-dione. Further provided are methods of using such pharmaceutical compositions for treating and/or ameliorating diseases and/or conditions associated with a cancer, such as prostate cancer.
Prostate cancer is the second leading cause of cancer-related death in American men. Current therapeutic treatments for prostate cancer may prolong life in patients, but the survival benefit is limited. Unfortunately most patients treated with conventional hormone therapy eventually relapse, and most patients treated with hormone therapy eventually develop castration-resistant prostate cancer (CRPC). Current treatments for CRPC are palliative only. New treatments are needed to inhibit, delay, and prevent the onset of CRPC.
5-Hydroxy-2-methylnaphthalene-1,4-dione can be administered to animals by intra-peritoneal injection or oral gavage after dissolution in various organic chemistry solvents or in polyethylene glycol (PEG). These methods of administration are undesirable for human usage in a clinical setting. There is a need for new oral formulations of 5-hydroxy-2-methylnaphthalene-1,4-dione that are acceptable for uses by human patients in a clinical setting.
It is therefore an aspect of this disclosure to provide improved pharmaceutical compositions of 5-hydroxy-2-methylnaphthalene-1,4-dione. It is a related aspect to provide pharmaceutical compositions of 5-hydroxy-2-methylnaphthalene-1,4-dione capable of eliciting and sustaining desirable responses in a patient in need thereof. It is another aspect of this disclosure to provide methods for treating and/or ameliorating diseases and/or conditions associated with a cancer, such as prostate cancer, using such compositions.

The present disclosure relates to pharmaceutical compositions containing Compound I. Solubility issues for Compound I make it difficult to produce pharmaceutical compositions of Compound I that are suitable for in vivo use in the clinic. An example of a formulation of Compound I that is difficult to administer in the clinic may include dissolution of Compound I in various organic chemistry solvents or in polyethylene glycol (PEG). Such formulations may be administered to animal subjects by intra-peritoneal injection or oral gavage, however, the methods of administering these formulations are undesirable for human usage in a clinical setting. In particular, it is desirable for a pharmaceutical composition of Compound I that can be administered to patients orally in a clinical setting. Thus, there is a need for new pharmaceutical compositions of Compound I that are acceptable for oral administration to human patients in a clinical setting. It is therefore in some alternatives of this disclosure to provide improved pharmaceutical compositions of Compound I suitable for oral administration to human patients.

In some embodiments, an improved pharmaceutical composition of Compound I may include Compound I, at least one pharmaceutically acceptable carrier, and at least one excipient. In some embodiments, the at least one excipient may be a binder, a disintegrant, a surfactant, or a stabilizer.
In some embodiments, the pharmaceutical composition is formulated as an emulsion. As used herein, emulsion refers to a colloidal dispersion of two immiscible liquids, for example, an oil and water (or other aqueous liquid, e.g., a polar solvent), one of which is part of a continuous phase and the other of which is part of a dispersed phase. The compositions described herein include emulsions, such as oil-in-water nanoemulsions or microemulsions (which may include an oil soluble phase dispersed in an aqueous phase, also called the water phase), in which the oil phase is the dispersed phase and the water phase is the continuous phase. Emulsions may be stabilized by one or more surfactants and/or co-surfactants and/or emulsion stabilizers. Surfactants form an interfacial film between the oil and water phase of the emulsion, providing stability. Nanoemulsions of the provided compositions may contain micelles, containing one or more surfactant surrounding a non-polar active ingredient, which are dispersed in the water phase. Exemplary of the provided emulsions are the provided liquid nanoemulsion concentrates and liquid dilution compositions made by diluting the concentrates, typically in an aqueous medium.
Emulsions may be formed by homogenization using high-speed and/or high-pressure homogenization. In high-speed homogenization, an emulsion may be formed by mixing the surfactant in water in a homogenizer at 500-100,000 rpm, such as 500, 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000, 15,000, 20,000, 25,000, 30,000, 40,000, 50,000, 60,000, 70,000, 80,000, 90,000, or 100,000 rpm, or an amount within a range defined by any two of the aforementioned values. In high-pressure homogenization, a coarse dispersion of an oil and aqueous phase may be passed through a small inlet orifice at an operating pressure in the range of 500-100,000 psi, such as 500, 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000, 15,000, 20,000, 25,000, 30,000, 40,000, 50,000, 60,000, 70,000, 80,000, 90,000, or 100,000 psi, or an amount within a range defined by any two of the aforementioned values, where the emulsion mixture is subjected to intense turbulence and hydraulic shear which may produce a fine emulsion with a small droplet size.
Emulsions may also be formed by microfuidization. Microfluidization may use a high pressure positive displacement pump operating at high pressures, such as up to 20,000 psi, which forces the emulsion product through an interaction chamber which consists of a series of microchannels. The emulsion flows through the microchannels on to an impringement area resulting in very fine emulsion droplets. The operating pressure and the number of passes of the coarse emulsion through the interaction chamber of the microfluidizer determine the particle size of the fine emulsion. The higher the operating pressure and the number of passes, the smaller the droplet size of the final emulsion.

3. Surfactants and Co-Surfactants
As used herein, “surfactant” refers to synthetic and naturally occurring amphiphilic molecules that have hydrophobic portion(s) and hydrophilic portion(s). Due to their amphiphilic (amphipathic) nature, surfactants and co-surfactants typically can reduce the surface tension between two immiscible liquids, for example, the oil and water phases in an emulsion, stabilizing the emulsion. Different surfactants can be characterized based on their relative hydrophobicity and/or hydrophilicity. For example, relatively lipophilic surfactants are more soluble in fats, oils and waxes, while relatively hydrophilic surfactants are more soluble in aqueous compositions, for example, water. Relatively amphiphilic surfactants are soluble in oil and water based liquids.
In some embodiments, the at least one pharmaceutically acceptable excipient can be selected from at least one or more surfactants. The at least one or more surfactants can be used, for example, as a wetting agent.

The pharmaceutical composition may be presented in a pack or dispenser device, which may contain one or more unit dosage forms containing Compound I. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, may be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. The pharmaceutical composition of Compound I may be placed in an appropriate container, and labeled for treatment of an indicated condition, such as for treatment of cancer.
In some embodiments, the relative amounts of Compound I, the pharmaceutically acceptable carrier(s), and excipient(s) by weight that can comprise a pharmaceutical composition of Compound I are shown in Table A.
In addition to the therapeutic properties of the pharmaceutical compositions described herein, it was surprisingly discovered that the pharmaceutical compositions of Compound I result in stable compositions having a long shelf life.

Some alternatives disclosed herein relate to pharmaceutical compositions of Compound I and methods of using such compositions with and without a hormone therapy agent, as described herein, to inhibit, delay, treat, or prevent prostate cancer cell growth or prostate cancer in a subject in need thereof.
A. Prostate Cancer
Prostate cancer is a leading cause of cancer-related death in the United States and the rest of the world. Advanced prostate cancer is resistant to hormone therapy, radiation and conventional chemotherapy. Although the 5-year survival rate is close to 100% for local disease, it drops to 30% for advanced cancer.
In the initial stages, prostate tumor growth is androgen dependent. Androgens are used by prostate cancer cells for both proliferation as well as regulation, and are vital for maintaining the growth and survival of the cancer cell. The main androgen that circulates is testosterone, which is mainly produced in the testes. Extragonadal sources of androgen synthesis do, however, exist and may play a role in the development of castration-resistant forms of prostate cancer. Generally, androgen dependent prostate cancer therapy focuses on minimizing testicular synthesis of androgens with luteinizing hormone releasing hormone (“LHRH”) agonists or antagonists. Some therapies also focus on modulating the androgen receptor itself, or its downstream signaling pathway.
Androgen dependent prostate cancer eventually progresses into castration-resistant prostate cancer (“CRPC”). Although these patients are “androgen insensitive,” researchers have discovered that androgen-responsive genes are still expressed, implying that the androgen-receptor signaling pathway may still be an important target in CRPC patients.
In 1986, surgeons developed a technique (using da Vinci Prostatectomy) that allowed the removal of the prostate while minimizing nerve damage, thereby decreasing adverse side effects. Unfortunately, should a patient's prostate-specific antigen (PSA) level remain above zero after radical prostatectomy is performed, this indicates that the prostate cancer has spread outside the capsule, i.e., disseminated, and to date, there is no curable treatment for this. Current hormonal and chemotherapy treatment regimens for such disseminated androgen dependent prostate cancers are palliative. Subsequently, even if there have been advances in the treatment of prostate cancer, finding new strategies for treatment of disseminated disease remains a crucial challenge. The section below provides more details on the use of pharmaceutical compositions of Compound I to inhibit, ameliorate, or delay the growth of cancer cells, in particular prostate cancer cells.
Most patients treated with existing hormone therapies eventually relapse with the emergence of castration-resistant prostate cancer (CRPC). Studies have shown that CRPC still relies on androgens for proliferation and that the androgen receptor (AR) is often highly expressed and transcriptionally active in CRPC cells. Steroids from the adrenal glands contribute to androgen receptor activity and some CRPC cells over-express enzymes that mediate androgen synthesis from adrenal steroids, and/or synthesize androgens de novo from cholesterol. Androgen receptor activity driven by residual androgens indeed participates in CRPC.
Prostate cancer can result in damage to the prostatic capsule. Prostate tumor cells can increase in size and number, which can increase the tension of the prostatic capsule. Eventually, the pressure against the prostatic capsule can cause the capsule to rupture. A broken, damaged, or ruptured prostate capsule may result in dissemination of the disease where prostate cancer spreads outside of the capsule. Some alternatives disclosed herein relate to pharmaceutical compositions of Compound I and methods of using such compositions with and without a hormone therapy agent, as described herein, to inhibit, delay, treat, or prevent damage or rupture of the prostatic capsule.
B. Pharmaceutical Compositions of Compound I as Anticancer Agents
Pharmaceutical compositions of Compound I have significant anti-cancer properties for oral administration to subjects in need of anti-cancer treatment. Without wishing to be bound by theory, it is contemplated that the primary mechanism of cytotoxic action of pharmaceutical compositions of Compound I is due to redox-cycling and electrophilic arylation. Compound I may be reduced by electron transfer from flavoprotein to a semiquinone radical, which can, in turn, reduce oxygen to superoxide. The resulting superoxide may consequently be converted into hydrogen peroxide, hydroxyl radicals, and/or peroxynitrite, all of which are highly reactive oxygen species (ROS) with potent cytotoxic and tumoricidial effects.
While still not wishing to be bound by theory, an additional antitumor mechanism of pharmaceutical compositions of Compound I may involve direct arylation of intracellular thiols leading to depletion of glutathione (GSH). Depletion of GSH may ultimately result in alkylation of cellular macromolecules and in their inactivation. Moreover, pharmaceutical compositions of Compound I may inhibit expression of multiple molecular targets, including protein kinase Cq (PKCq), phosphatidylinositol 3-kinase (PI3K), AKT, activation of transcription factors activator protein-1 (AP-1), nuclear factor-κB (NF-κB), and signal transducer and activator of transcription 3 (Stat3) in prostate carcinoma cells. Such activities may contribute to the tumoricidial effects of pharmaceutical compositions of Compound I.
Moreover, while still not wishing to be bound by theory, an additional antitumor mechanism for pharmaceutical compositions of Compound I may involve inhibition of microtubule polymerization and binding to tubulin. Because one of the defining characteristics of cancer cells is a significantly increased rate of cell cycle entry and/or mitosis, cancer cells are more vulnerable to agents that affect microtubule polymerization than normal cells. Compound I may recognize the colchicine binding site of tubulin and inhibit in vitro tubulin polymerization.
Pharmaceutical compositions of Compound I may result in slower growth of androgen independent prostate cancer, and that the mechanism behind the slower growth may be due to apoptosis of prostate tumor cells. Pharmaceutical compositions of Compound I may induce cell cycle entry, mitosis, and/or apoptosis of androgen-dependent cancer cells.
It is contemplated that pharmaceutical compositions of Compound I have anti-cancer activity and that this anti-cancer activity, especially with respect to prostate cancer, may be significantly and unexpectedly improved (e.g., synergy may be obtained) when the pharmaceutical compositions of Compound I are provided to a subject orally in conjunction with a blockade of testosterone/androgen/DHT (e.g., castration or a hormone treatment therapy, such as hormonal ablation). For example, it is believed that the administration of a pharmaceutical composition of Compound I to a subject in need thereof will effectively inhibit the growth of prostate cancer cells and thereby reduce the incidence of fatal prostate cancer. The combination of a pharmaceutical composition of Compound I with an antioxidant, such as ascorbic acid, alpha lipoic acid, n-acetyl cysteine (NAC), lycopene, tocopherol, or tocotrienol, or others may also be beneficial. The combination of a pharmaceutical composition of Compound I and mitomycin C may also be beneficial in treating subjects with advanced solid tumors, advanced lung cancer, and advanced gastrointestinal cancer. By administering a combination of a pharmaceutical composition of Compound I and an antioxidant or plurality of antioxidants, such as vitamin C, to subjects having prostate cancer, it is contemplated that a reduction in tumor cell numbers and PSA (prostate cancer specific antigen) will be obtained.
Alternatively or in addition, it is contemplated that pharmaceutical compositions of Compound I have anti-cancer activity and that this anti-cancer activity, especially with respect to prostate cancer, may be significantly improved (e.g., synergy may be obtained) when the compositions are provided in conjunction with certain hormonal therapy agents, described in more detail below. It is believed that Compound I alters the androgen receptor pathway. Accordingly, it is preferred that pharmaceutical compositions of Compound I are provided in combination or in co-administration with a testosterone synthesis inhibitor that do not alter the androgen receptor pathway (e.g., a testosterone synthesis inhibitor that does not bind to the androgen receptor, such as orteronel or VT-464).
It is contemplated herein that a significantly improved inhibition of prostate cancer cell growth may be obtained when castration, hormonal castration, hormonal ablation, or hormone therapy are provided during the time a patient receives the combination of antioxidant (e.g., ascorbic acid) with a pharmaceutical composition of Compound I. Provided herein is an improved method for treating a subject suffering from prostate cancer with a pharmaceutical composition of Compound I and androgen ablation therapy to subjects with PSA values above zero after radical prostatectomy, i.e., when they have androgen-dependent disseminated disease. Today there is no cure for this and patients currently receive only palliative treatment, including hormone therapy alone.
It is contemplated that pharmaceutical compositions of Compound I are highly oxidative and induce oxidative stress in cells. Accordingly, such compositions may be used to inhibit or ameliorate prostate cancer cell growth and that a significantly improved inhibition or amelioration of prostate cancer cell growth may be obtained when castration, hormonal castration, hormonal ablation, or hormone therapy are provided before, during, and/or after the time a patient receives such compositions.
It is contemplated that a pharmaceutical composition of Compound I may be used to inhibit or ameliorate prostate cancer cell growth and that a significantly improved inhibition or amelioration of prostate cancer cell growth may be obtained when castration, hormonal castration, hormonal ablation, or hormone therapy are provided before, during, and/or after the time a patient receives the compositions.
As mentioned above, although providing a subject that has cancer (e.g., prostate cancer) with a pharmaceutical composition of Compound I may inhibit the growth of cancerous cells, a significantly improved inhibition of cancer cell growth (e.g., prostate cancer cell growth) may be obtained by providing a pharmaceutical composition of Compound I, separately or in a mixture, co-administration, or combination, in conjunction with a therapy that reduces the androgen levels of the patient and/or disrupts androgen receptor signaling (e.g., castration, hormonal castration, hormonal ablation, or hormone therapy). That is, some alternatives include methods of inhibiting cancer cell growth (e.g., prostate cancer cell growth or progression of prostate cancer disease) or treating or preventing a cancer (e.g., prostate cancer), wherein a subject having a cancer (e.g., prostate cancer) is provided a pharmaceutical composition of Compound I while reducing the amount of androgens in the subject (e.g., providing castration, hormonal castration, hormonal ablation, or hormone therapy). Optionally, the inhibition of cancer (e.g., prostate cancer) or a marker thereof (e.g., PSA) is evaluated during or after the treatment (e.g., after the combination of a pharmaceutical composition of Compound I and hormone therapy is provided). Stated differently, some alternatives include a combination of a pharmaceutical composition of Compound I, formulated for administration separately or together, and an androgen deprivation therapy (e.g., castration, hormonal castration, hormonal ablation, or hormone therapy) for use in inhibiting, ameliorating or delaying the growth of prostate cancer cells or treating or preventing prostate cancer. The section below describes some of the approaches that may be used to deplete the levels of androgen in the subject so as to provide the treatments and treatment protocols described above.
C. Hormone Therapy
Hormone therapy for treating prostate cancer, or inhibiting or delaying prostate cancer cell growth, can also be called androgen deprivation therapy (ADT), chemical castration, or androgen ablation therapy. Androgens can fuel the growth of prostatic cells, including both healthy prostatic cells and cancerous prostatic cells. In some alternatives, a subject suffering from prostate cancer is provided with a hormone therapy agent that reduces the subject's androgen levels.
Without wishing to be bound by theory,
In some alternatives, a hormonal therapy agent is provided to a patient to selectively inhibit the androgen biosynthesis pathway. Selective inhibition of this pathway is desirable given that a patient receiving such an agent will not require hormone replacement therapy. Hormone replacement therapy is often required when non-selective hormonal therapy agents, such as abiraterone are provided, resulting in the inhibition of mineralocorticoid biosynthesis and/or glucocorticoid biosynthesis. Such inhibition may afford side effects, causes the patient to take additional drugs, reduces patient compliance, and/or impairs the patient's quality of life.
In some alternatives, a hormonal therapy agent is provided to a patient to selectively inhibit the 17,20-lyase activity of CYP17. Such inhibition will result in the selective decrease of DHEA and andostenedione production, while not affecting mineralocorticoid biosynthesis and glucocorticoid biosynthesis. Indeed, selectivity targeting CYP17's 17,20-lyase activity, while leaving the 17α-hydroxylase activity of CYP17 relatively undisturbed should afford limited side effects and be less likely to require the concomitant administration of a hormone replacement, such as prednisone.
Inhibitors of 17,20-lyase activity of cytochrome P450-17 (“CYP-17”) are known in the art. Steroid-type inhibitors of 17,20-lyase activity are disclosed in, for example, WO 92/15404, WO 93/20097, EP-A 288053, and EP-A 413270, such compounds being incorporated herein by reference.

No. 5,491,161; WO99/18075; WO99/54309; WO03/027085; and EP0724591, such compounds being expressly incorporated herein by reference in their entireties. Additional compounds include, but are not limited to, compounds disclosed in U.S. Pat. No. 8,236,962; U.S. Pat. No. 8,263,635; and U.S. Patent Application No. 20100305078; the compounds described therein being expressly incorporated herein by reference in their entireties.

See Kaku et al., Bioorg. Med. Chem. (2011) 19, 6383-99.
Moreover, preferred examples of selective 17,20-lyase inhibitors include orteronel and VT-464. See Kaku et al., Bioorg. Med. Chem. (2011) 19, 6383-99; Eisner et al. J. Clin. Oncol. “VT-464: A novel, selective inhibitor of P450c17(CYP17)-17,20 lyase for castration-refractory prostate cancer (CRPC).
One of skill in the art can readily determine additional examples of selective 17,20-lyase inhibitors by screening inhibitors of CYP17 for both 17,20-lyase inhibition and hydroxylase inhibition, such as 17α-hydroxylase inhibition. In some alternatives, a compound is a selective inhibitor if there is a 5-fold difference between lyase and hydroxylase inhibition.

As mentioned above, prostate cancer can be treated by hormone therapy agents, however, hormone therapy agents alone can result in the development of castration-resistant prostate cancer (CRPC). For example, hormonal therapy can initially deliver a response in a subject suffering from prostate cancer, however, the return of hormone-refractory tumors invariably prevents long-term patient survival. More effective strategies are needed to extend life expectancy and improve the quality of life for patients with advanced prostate cancer. Accordingly, some aspects disclosed herein concern methods for ameliorating or inhibiting or reducing or delaying the onset of castration-resistant prostate cancer (CRPC) or treatments (e.g., compositions used for the purpose of ameliorating or inhibiting or reducing or delaying the onset of CRPC), whereby a pharmaceutical composition of Compound I is provided before, during and/or after providing cyproterone acetate, finasteride, abiraterone, flutamide, nilutamide, bicalutamide, diethylstilbestrol (DES), megestrol acetate, fosfestrol, estamustine phosphate, leuprolide, triptorelin, goserelin, histrelin, buserelin, abarelix, degarelix, orteronel, VT-464, enzalutamide, ARN-509, vinclozolin, galeterone, ketoconazole, L-39, aminoglutethimide, prochloraz, dutasteride, izonsteride, turosteride, epristeride, genisterin, gossypol, equol, 18β-glycyrrhetinic acid, altraric acid, N-butylbenzene-sulfonamide, 3,3′-diindolylmethane, deslorelin, nafarelin, cetrorelix, or ganirelix or any combination thereof. Optionally, the inhibition in prostate cancer cell growth, an inhibition in prostate cancer advancement, or delaying the onset of CRPC is evaluated before during or after the therapy. Optionally, a patient with prostate cancer is classified as a subject in need of an agent that ameliorates, reduces, delays, or inhibits the onset of CRPC prior to receiving one or more of the combination therapies described herein. A subject can be identified as one in need of a therapy for prostate cancer using conventional clinical pathology including, biopsy, CT scan, PET scan, MRI, digital examination, Gleason score, or PSA level.
As mentioned above, prostate cancer can be treated by hormone therapy agents, however, hormone therapy agents alone can result in damage to the prostatic capsule, including rupture of the prostate capsule, which may lead to dissemination of prostatic cancer cells outside of the capsule. More effective strategies are needed to prevent rupture of the prostatic capsule to extend life expectancy and improve the quality of life for patients with prostate cancer. Accordingly, some aspects disclosed herein concern methods for ameliorating or inhibiting or reducing or delaying damage or rupturing of the prostatic capsule or treatments (e.g., compositions used for the purpose of ameliorating or inhibiting or reducing or delaying the damage or rupturing of the prostatic capsule), whereby a pharmaceutical composition of Compound I is provided before, during and/or after providing cyproterone acetate, finasteride, abiraterone, flutamide, nilutamide, bicalutamide, diethylstilbestrol (DES), megestrol acetate, fosfestrol, estamustine phosphate, leuprolide, triptorelin, goserelin, histrelin, buserelin, abarelix, degarelix, orteronel, VT-464, enzalutamide, ARN-509, vinclozolin, galeterone, ketoconazole, L-39, aminoglutethimide, prochloraz, dutasteride, izonsteride, turosteride, epristeride, genisterin, gossypol, equol, 18β-glycyrrhetinic acid, altraric acid, N-butylbenzene-sulfonamide, 3,3′-diindolylmethane, deslorelin, nafarelin, cetrorelix, or ganirelix or any combination thereof. Optionally, a patient with prostate cancer is classified as a subject in need of an agent that ameliorates, reduces, delays, or inhibits the damage or rupturing of the prostatic capsule prior to receiving one or more of the combination therapies described herein.

The dosage may be a single one or a series of two or more given in the course of one or more days, as is needed by the subject. In some alternatives, a pharmaceutical composition of Compound I disclosed herein will be administered for a period of continuous therapy, for example for a week or more, or for months or years. In some alternatives, a pharmaceutical composition of Compound I disclosed herein can be administered one time per day.
Multiple doses of Compound I can be administered to a subject. For example, a pharmaceutical composition of Compound I disclosed herein can be administered once per month, twice per month, three times per month, every other week (qow), once per week (qw), twice per week (biw), three times per week (tiw), four times per week, five times per week, six times per week, every other day (qod), daily (qd), twice a day (qid), or three times a day (tid), over a period of time ranging from one day to one week, from two weeks to four weeks, from one month to two months, from two months to four months, from four months to six months, from six months to eight months, from eight months to 1 year, from 1 year to 2 years, or from 2 years to 4 years, or more.
In some alternatives, a pharmaceutical composition of Compound I disclosed herein and a hormone therapy agent can be cyclically administered to a patient. Cycling therapy involves the administration of a first active ingredient for a period of time, followed by the administration of a second active ingredient for a period of time and repeating this sequential administration. Cycling therapy can reduce the development of resistance to one or more therapies, avoid or reduce the side effects of one or more therapies, and/or improve the efficacy of treatment. In some alternatives, a pharmaceutical composition of Compound I disclosed herein and a hormone therapy agent are administered in a cycle of less than 3 weeks, once every two weeks, once every 10 days, or once every week. The number of cycles can be from 1 to 12 cycles, or from 2 to 10 cycles, or from 2 to 8 cycles.
The daily dosage regimen for an adult human patient may be the same or different for two active ingredients provided in combination. In some alternatives, the active ingredient is Compound I. In some alternatives, the active ingredient is a hormone therapy agent. In some alternatives, both an active ingredient of Compound I and an active ingredient of a hormone therapy agent are administered to a subject. For example, Compound I can be provided at a dose of between 0.01 mg and 3000 mg, while a hormone therapy agent can be provided at a dose of between 1 mg and 700 mg. The dosage or each active ingredient can be, independently, a single one or a series of two or more given in the course of one or more days, as is needed by the subject. In some alternatives, the active ingredients will be administered for a period of continuous therapy, for example for a week or more, or for months or years. In some alternatives, a pharmaceutical composition of Compound I disclosed herein can be administered one time per day. In some alternatives, the hormone therapy agent can be administered once a week.
In instances where human dosages for active ingredients have been established for at least some condition, those same dosages may be used, or dosages that are between 0.1% and 500%, more preferably between 25% and 250% of the established human dosage. Where no human dosage is established, as will be the case for newly-discovered pharmaceutical compositions, a suitable human dosage can be inferred from ED50 or ID50 values, or other appropriate values derived from in vitro or in vivo studies, as qualified by toxicity studies and efficacy studies in animals.
As will be understood by those of skill in the art, in certain situations it may be necessary to administer the active ingredients disclosed herein in amounts that exceed, or even far exceed, the above-stated, preferred dosage range in order to effectively and aggressively treat particularly aggressive diseases.
Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the modulating effects, or minimal effective concentration (MEC). The MEC will vary for each active ingredient but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations. Dosage intervals can also be determined using MEC value. Compositions should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.
Active ingredients disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular active ingredient, or of a subset of the active ingredients, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds in an animal model, such as mice, rats, rabbits, or monkeys, may be determined using known methods. The efficacy of a particular active ingredient may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, route of administration and/or regime.

Additional alternatives are disclosed in further detail in the following examples, which are not in any way intended to limit the scope of the claims.
All procedures involving mice were approved by the Institutional Animal Care and Use Committee of Explora Biolabs (San Diego, Calif.) and carried out according to NIH recommended procedures and precautions. All mice were purchased from Jacksons laboratory (Bar Harbor, Me.). Mice were housed at a maximum of two per cage, under standard room conditions, with ad libidum food and water. Every effort was made to minimize animal suffering.
Mice were anesthetized before surgery and received analgesics after surgery according to IACUC-approved procedures. Surgeries were performed in a sterile laminar flow hood with proper instrument sterilization and approved procedures.
Dorsal skinfold chambers and surgical instruments are autoclaved before use. Saline used to keep tissue moist during surgical preparation is mixed with gentamicin (50 μl/ml).
Male Nude mice (25-35 g body weight) are anesthetized (7.3 mg ketamine hydrochloride and 2.3 mg xylazine/100 g body weight, i.p.) and placed on a heating pad. Two symmetrical titanium frames are implanted into a dorsal skinfold, so as to sandwich the extended double layer of skin. A 15 mm full thickness circular layer is excised. The underlying muscle (M. cutaneous max.) and subcutaneous tissues are covered with a glass coverslip incorporated in one of the frames. After a recovery period of 2-3 days, prostate tissue and cancer cell spheroids are carefully placed in the chamber. Small circular Band Aids are applied on the backside of the chamber after surgery to prevent scratching. Before surgery, Buprenorphine (0.1 mg/kg) is given IP. After surgery Meloxicam is given in the drinking water for 4 days Meloxicam (5.0 mg/ml), is added at 35 μl per 100 ml of water to be medicated.
Mice are anesthetized with 7.3 mg ketamine hydrochloride and 2.3 mg xylazine/100 g body weight, i.p. A lateral incision across the scrotum is made and the testes are individually ligated and excised. The wound is cauterized. The incision is then sutured and sealed with Nexaband® acrylic.
PTEN-P2 and PTEN-CaP2 mouse prostate cancer cells were generously provided by the laboratory of Dr. Hong Wu as described in Jiao et al., Cancer Research, 67:6083-91 (2007). Expression of histone H2B-GFP fluorescent protein in PTEN-P2 and PTEN-CaP2 cells was achieved by infection with a viral vector followed by selection in geneticin.
TRAMP-C2/H2B-GFP cells were grown in phenol-free RPMI containing 10% FBS, 2 mM L-glutamine, 100 U/ml penicillin/100 μg/ml streptomycin, insulin-selenium-transferrin (10 μg/ml insulin), DHT 10−8M final and G418 (100 μg/ml). PTEN-CaP2/H2B-GFP and PTEN-P2/H2B-GFP were grown in phenol-free, high-glucose DMEM (Dulbecco's Modified Eagle's Medium) containing the same additives as TRAMP-C2 cells. G418 at 100 μg/ml or 50 μg/ml was added to maintain stable expression of H2B-GFP in PTEN-P2 and PTEN-CaP2, respectively.
Preparation of tumor spheroids: Liquid overlay plates were generated using 1% molecular biology grade agarose melted in cell culture medium and plated in round bottom 96 well plates at 50 ul/well. Tumor cells grown as pre-confluent monolayers were trypsinized and diluted to a final volume of 1,000,000 cells/ml. Viability was determined by Trypan blue. Cells were placed onto the cooled agarose (70 μl/well) and allowed to compact into spheroids for 24 hours. The spheroids were picked with a pipette and transferred into serum-free media for implantation in the chambers.
IntraVital Microscopy (IVM) can be used to visualize tumors in animals and analyze various aspects of cancer physiology such as tumor vascularization, cell migration and metastasis. An advantage of IVM includes the real-time analysis of dynamic processes with single-cell resolution. IntraVital microscopy offers the possibility to follow tumor growth in a non-invasive, non-destructive manner. The application of IVM can be limited to animal models that bear visually accessible tumors. Therefore, the dorsal skinfold chamber model described above can be compatible with IVM. Using IVM can permit a number of parameters to be measured in living animals and as a function of time, including tumor growth, angiogenesis, infiltration by immune cells, tumor cell migration, mitosis (cell-division) and apoptosis (programmed cell death), all in the context of the host and in real time.
Orthotopic injection of PTEN-P2 and TRAMP-C2 for survival studies: Mice were anaesthetized and an incision was made through the skin and peritoneum. A total of 30,000 cells were suspended in Matrigel and slowly injected into the dorsal lobe of the prostate using a 30-gauge needle. Matrigel was used to prevent the leakage of cells out of the site of injection. A Q-tip was held over the injection site for 1 min to prevent bleeding and spill after removal of the needle. The abdominal wall was closed by surgical silk sutures.
Fox1/Nu or C57BL/6J mice were used as recipients for PTEN-P2 and TRAMP-C2 cells, respectively. Mice were surgically castrated 6 weeks later, when tumors were established, and Compound I treatment was initiated 4-5 days later. The number of days mice lived following treatment initiation was recorded for each animal. A few mice were found dead upon daily inspection, while others were euthanized in agreement with our IACUC regulations, including mice showing weight losses of more than 15% and mice showing signs of pain though posture and lack of grooming were euthanized.
Unless otherwise indicated, Compound I was administered by oral gavage in a sesame oil (Carrier A) formulation. Compound I was dissolved in DMSO then in oil at a concentration of 0.25 mg/ml (weight/volume) with a final DMSO concentration of 0.5% (vol/vol), and administered to mice at 1 mg/kg. In some experiments, Compound I dissolved in a mixture of poly-ethylene glycol/DMSO 30% (w/v) was administered via intra-peritoneal injection.
A single-dose maximum tolerated dose (MTD) phase A study and a 7-day dose range-finding (DRF) phase B study were conducted in Sprague Dawley rats by MPI Research, Inc. (Mattawan, Mich.). A total of 62 males and 62 females rats were assigned to the study, which was performed in accordance with all current regulations. Animals were housed in standard conditions and had ad libitum access to food and water. Healthy animals of each sex were randomized into treatment groups using a standard, by weight, measured value randomization procedure. Compound I was administered by oral gavage, once at each dose level in Phase A (acute), or once daily for 7 consecutive days in Phase B. Oral gavage was chosen because the oral route is the intended route of administration in humans. Animals were observed twice daily for morbidity and mortality and were euthanatized for humane reasons where appropriate. An initial starting dose of 50 mg/kg was used for Phase A. Subsequent doses were increased or decreased based on the response to the preceding dose. The maximum tolerated dose (MTD) was identified as the highest dose level that did not produce mortality, more than a 10% decrement in body weight, or clinical signs of toxicity. The dose levels used in Phase B were based on the MTD identified in Phase A.
Means of tumor sizes within treatment groups and standard errors were calculated. The statistical significance of differences within treatment arms (i.e. efficacy of a treatment as a function of time) was calculated using one-way repeated-measures ANOVA with post hoc Bonferroni correction. The statistical significance of differences between treatment arms was calculated using two-way repeated-measures ANOVA with post hoc Bonferroni correction. The difference between survival curves was calculated using the non-parametric log-rank test.
The maximum quantity of Compound I that can be completely dissolved at 25° C. in the several aqueous buffers and other solvents was evaluated using HPLC. All solubility samples were saturated with a similar amount of excess Compound I. Samples were shaken overnight at 25° C., placed in 0.22 μm nylon centrifuge tube filters and centrifuged @ 14000 rpm for 10 minutes prior to HPLC analysis. Samples were injected with a 250 μg/ml nominal concentration. For samples of unknown concentration, dilutions were made to target the linear range of the method. All samples were quantified based on a linear standard curve. Measurements were performed by Pharmatek Laboratories, Inc. (San Diego, Calif.) with industry-standard quality controls. As shown in Tables 1 and 2, it was found that Compound I is mostly insoluble in aqueous media but has good solubility in organic solvents such as alcohols, acetone and other solvents. It was found that Compound I was well soluble in Carrier A (Table 2).
The maximum quantity of Compound I that can be completely dissolved at 25° C. in the several solvents was evaluated using absorption spectrophotometry. Supersaturated dispersions of Compound I in each solvent were incubated at 25° C. for 72 h on a rotary shaker. Samples were then centrifuged at 10,000×g for 10 minutes and the resulting supernatant was filtered through a syringe filter (0.45 um). An aliquot of filtrate was then diluted with methanol or extracted into methanol. The concentration of Compound I was determined using absorption spectrophotometry (DU-640, Beckman Coulter) at 410 nm (e=3,500 dm3 mol−1 cm−1), as shown in
For the purposes of establishing material handling practices, Compound I was evaluated for water uptake in various controlled conditions. Compound I was exposed to 25° C./60% relative humidity and 40° C./75% relative humidity for up to one day. Approximately 200 mg of Compound I was accurately weighed into separate glass vials and placed uncapped in stability chambers. At various time points, the vials were removed, stoppered and crimped, and the water content for Compound I powder was determined by standard Karl Fischer coulometric analysis. The results indicate that Compound I appears to be anhydrous. Compound I was not sensitive to water uptake at up to 75% relative humidity. The water content of Compound I at the indicated temperature and RH (relative humidity) are shown in Table 4.
Forced degradation studies were performed to determine the stability of Compound I in various aqueous formulations. Compound I formulations were prepared at approximately 5 mg/g (˜4.6 mg/mL assuming a density of 0.92 g/mL) in various aqueous media, as listed in Tables 5 and 6. The aqueous formulations were placed in stability chambers and subjected to conditions of 25° C./60% relative humidity (RH) and 40° C./75% relative humidity (RH). Samples were pulled from the formulations at 3 and 10 days. At each time point, samples were pulled from the stability chambers, diluted 20× to the nominal concentration using positive displacement pipettes and 50/50 ethanol/hexane as the diluent, and analyzed via HPLC for purity. The purity results are shown in Table 5. The potency results are shown in Table 6. Within the physiological pH range (around pH 7), less than 10% of initial Compound I remained in the solution after 1 week. Compound I was stable in aqueous acid, but not in basic or neutral aqueous conditions.
‡Precipitation was observed. Precipitation may have also occurred in buffered media pH = 6-10 at t = 1 week.
‡The purity of many of the aqueous pH stability samples was difficult to assess precipitation.
Forced degradation studies were performed to determine the stability of Compound I in various formulations. Compound I formulations were prepared at approximately 5 mg/g (˜4.6 mg/mL assuming a density of 0.92 g/mL) in various solvents, as listed in Tables 7 thorough 10. The formulations were placed in stability chambers and subjected to conditions of 25° C./60% relative humidity (RH) and 40° C./75% relative humidity (RH). Samples were pulled from the formulations at 3 and 10 days. At each time point, samples were pulled from the stability chambers, diluted 20× to the nominal concentration using positive displacement pipettes and 50/50 ethanol/hexane as the diluent, and analyzed via HPLC for purity. The purity results are shown in Table 7. The potency results are shown in Table 8. Most purity and potency values trended downward throughout the stability study, as shown in Tables 7 and 8. Stability was very good in most organic solvents but not in Tween-20 or Tween-80 surfactant formulations in which 50% or more Compound I was lost. The formulations of Compound I in PEG were 50% stable at 40° C./75%, whereas its stability in Carrier A was excellent. Indeed, as shown in Tables 9 and 10, no significant degradation was observed in the Carrier A formulations after up to 10 days of storage at any of the temperatures and relative humidity conditions tested.
‡Precipitation was observed.
‡Precipitation was observed.
The efficacy of the formulation of Compound I in Carrier A for oral administration was compared to the previous formulation of Compound I in poly-ethylene glycol (PEG) for intra-peritoneal injection (i.p.). These experiments were performed using Intra Vital Microscopy (IVM) in a pseudo-orthotopic prostate chamber model in which minced prostate tissue is grafted in chambers surgically placed in the dorsal skinfold of mice, and allowed to vascularize. Small tumor cells spheroids were then placed on the prostate tissue, creating a biologically relevant prostatic environment. The tumor cells that express fluorescent H2B-GFP and can be detected in situ and in real-time through the microscopy window of the dorsal chamber.
Epithelial cell lines derived from the prostate tumor of a PTEN-null mouse were used. Mouse prostate cancer cells PTEN-P2 are heterozygous for PTEN deletion and do express protein PTEN. They are also androgen receptor (AR) positive and androgen-dependent for growth.
Titanium chambers were placed by surgery in nude mice and syngeneic prostate tissue was grafted into the chamber two days later. Tumor spheroids containing 70,000 mouse prostate cancer cells PTEN-P2/H2B-GFP were placed on the prostate tissue 7 days later. In this particular experiment all the mice were castrated 21 days later and before initiation of Compound I treatment to investigate the combination of castration with Compound I. Compound I, which was previously shown to synergize with castration in mice, was administered orally at various doses in a Carrier A formulation, or via intra-peritoneal injection at 1 mg/kg/day in DMSO/PEG formulation. Changes in tumor size were monitored by IVM and quantified. Results are expressed as tumor size relative to their size at the start of treatment and as a function of time.
As shown in
A single-dose maximum tolerated dose (MTD) study and a seven consecutive day dose-range finding study were carried out in Sprague Dawley by orally administering a formulation of Compound I in Carrier A. In the MTD phase, doses of 50, 100, 200 and 300 mg/kg were administered once to Sprague Dawley rats by oral gavage. The single-dose MTD of Compound I in rats was found at 100 mg/kg. Acute administration of Compound I at 200 or 300 mg/kg resulted in unscheduled deaths in male rats on Days 1 and 2 but not in females. At these high doses, the rats exhibited adverse clinical events such as decreased activity, abnormal body carriage and piloerection. Male rats also exhibited impaired righting reflex and slow or shallow breathing.
Daily doses of 0 (vehicle), 10, 30 and 100 mg/kg were then administered to Sprague Dawley rats by oral gavage for seven days for the dose-range finding study. Morbidity/mortality occurred both in male and female rats at 100 mg/kg/day beginning on day 3, resulting in early termination of all animals on Day 5. Adverse events included decreased body weight or decreased body weight gain, decreased food consumption, adverse effects on various pathological parameters and Compound I-related macroscopic and microscopic abnormalities in multiple organs. At the 30 mg/kg/day mid-dose level, minimal increases in mean serum total bilirubin concentration and alkaline phosphatase activity were observed. Minimal to mild non-adverse microscopic abnormalities in various organs, indicative of inflammation, were noted in both sexes. Compound I-related effects at the 10 mg/kg/day low-dose level were limited to minimal changes noted in the teeth of one male. The toxicity profile of Compound I is encouraging considering that the drug is effective in rodents at much lower doses. This toxicity-to-effectiveness dose ratio provides, potentially, a wide therapeutic window.
Clinical trials in cancer research are performed against the current standard treatment, which for prostate cancer is androgen deprivation therapy (ADT). Surgical castration in the mouse effectively depletes circulating androgens and is accepted in the art as an appropriate model for ADT in humans. Therefore, the investigative treatment of castration combined with Compound I was compared to standard treatment with surgical castration alone. Six cohorts of mice totaling 52 mice were castrated and treated or not with Compound I. Some of these cohorts were used as controls for other investigative treatment arms. Comparing the trend lines of several separate cohorts, as shown in
An orthotopic model of prostate cancer in which 30,000 PTEN-P2 mouse cells were injected into the prostate of Fox1/Nu mice was used. Mice were castrated 5 weeks after the PTEN-P2 mouse cells were injected into the prostate, which allowed the tumors to become established. Oral administration of Compound I in Carrier A was initiated one week later at a dose of 1 mg/kg/day. The number of days mice lived following treatment initiation was recorded for each animal.

These results surprisingly demonstrate that the combination of an orally administered formulation of Compound I in Carrier A with castration not only causes tumor regression but also increases the survival of model mice compared to castration alone.
The effect of an oral formulation of Compound I in combination with various drugs that chemically induce androgen ablation was assessed. Thus, the effect of an oral formulation of Compound I in combination with androgen deprivation therapy (ADT) was assessed.
These experiments were performed using IVM in the pseudo-orthotopic prostate chamber model with PTEN-P2/H2B-GFP cells as described above. Oral administration of Compound I in Carrier A was initiated at a dose of 1 mg/kg/day. Chemical ADT was compared to surgical castration to control for the efficacy of chemical ADT at stopping tumor growth, and an oral formulation of Compound I was combined with either chemical ADT or surgical castration. The results are shown in
Compound I in Combination with Androgen Receptor Antagonists
Androgen receptor (AR) antagonists may be used as an alternative to chemical ADT. The effect of Compound I combined with the two AR antagonists, bicalutamide (CASODEX®) and enzalutamide (XTANDI®), was assessed.
Summary of Oral Formulation of Compound 1 in Combination with ADT and AR Antagonists
A summary of experimental results on the efficacy of a formulation of Compound I in Carrier A administered orally in combination with surgical castration, leuprolide, leuprolide, degarelix, abiraterone, orteronel, dutasteride, bicalutamide, and enzalutamide for treating prostate cancer is shown in Table 11.
Mouse prostate cancer cells PTEN-CaP2 were initially derived from the PTEN-P2 cell line and are homozygous for PTEN deletion. Complete ablation of PTEN results in intrinsic androgen-independence in the PTEN-null model. Although PTEN-CaP2 tumors express AR, they are resistant to castration in the absence of prior exposure to ADT. This is illustrated in
The dynamic (shear) viscosity of pharmaceutically acceptable Carrier A (sesame oil) alone and a pharmaceutical composition containing Compound I and pharmaceutically acceptable Carrier A at a concentration of 50 mg Compound I per 1 mL of Carrier A was determined using a NDJ-5S digital rotary viscometer at various temperatures. The temperature was adjusted using an Isotemp 202 water bath. The results are shown in
The following example demonstrates methods for preparing self-nanoemulsifying formulations comprising Compound I.
Capryol™ 90 (propylene glycol monocaprylate) was selected as an oil phase and Labrasol™/Kolliphor® RH40 (caprylocarpoyl polyoxyl-8 glycerides/polyoxyl castor oil) as a nonionic surfactant/cosurfactant mixture (at a 1:1 ratio) based on pre-formulatory studies of miscibility of various systems of oils and surfactants, including the water solubility and Compound I solubility.
To identify a monophasic optically isotropic nanoemulsion region, a series of mixtures of propylene glycol monocaprylate with surfactant/cosurfuctant Labrasol™/Kolliphor® RH40 (caprylocarpoyl polyoxyl-8 glycerides/polyoxyl castor oil) (1:1, w/w) were prepared. Pseudoternary phase diagrams were constructed using progressive water titration. The established pseudoternary phase diagram shown in
Samples from nanoemulsion area appeared translucent whereas mixtures with a higher percentage of propylene glycol monocaprylate oil phase led to formation of opalescent coarse dispersions (
Analysis of particle size distribution over time showed a polydisperse profile and instability of systems with S-CoS/O<1, while systems with S-CoS/O at 1.35 showed narrow PDI and stability of size distribution over time (
The following example demonstrates methods for preparing oleic acid-based microemulsion formulations that comprise Compound I.
An emulsion of oleic acid (10% w/w) alone or saturated with Compound I (51.8 mg/ml) in various amounts of polysorbate 80, including from 0.25-4.0% (w/w) in deionized water was homogenized with a high speed homogenizer (Biospec Products, Inc.) at 30,000 rpm for 5 minutes. The homogenate was subjected to high-pressure homogenization using pneumatically controlled EmulsiFlex-C3 (Avestin) at 5000 psi in recirculating mode for 15 to 20 minutes. Microemulsions were characterized for particle size distribution and zeta-potential by ZetasizerNano-ZS (Malvern). Photon correlation microscopy (PCS) indicated identical size of microemulsions for empty microemulsion (133 nm (PDI 0.178)) and microemulsions comprising Compound I (133 nm (PDI 0.167)) (
To analyze an antiproliferative activity of microemulsions comprising Compound I, prostate carcinoma cells P2-PTEN were exposed to increasing dilutions of: a) control microemulsions (ME—control); b) microemulsions comprising Compound I (ME—Compound I); and c) free Compound I. The cytotoxicity was determined after a 24 hour exposure using a formazan-based assay (CellTiter 96 AQueous™ on solution cell proliferation assay, Promega). Results showed that microemulsions comprising Compound I demonstrated significantly increased cytotoxicity compared to free Compound I (
