METHODS FOR THE TREATMENT OF CANCERCross-Reference To Related Applications
[0001] This application claims priority to United States Provisional Application No. 63 / 646,420 titled “METHODS FOR THE TREATMENT OF CANCER” filed May 13, 2024, the entire contents of which are incorporated by reference herein.Field of the Invention
[0002] This disclosure relates to compounds, pharmaceutical formulations comprising them, and methods of using the compounds and compositions for treating cancer.Background of the disclosure
[0003] Therapies to prevent cancer cell survival, invasion and migration would be a major therapeutic breakthrough. Recent work has uncovered a critical role for the mammalian stress-responsive transcription factor, HSF1, in cancer cell initiation, proliferation, survival, invasion and metastasis. Furthermore, HSF1 was discovered as one of six metastasispromoting genes in malignant melanoma. HSF1 is normally activated by cellular stresses that cause protein misfolding, activating the expression of protein chaperones that protect cells from protein damage. In many distinct cancers, however, HSF1 protein abundance and activity are dramatically elevated and HSF1 drives a program of gene expression that regulates pathways to support tumor cell initiation, growth, survival, invasion and metastasis, in both tumor cells and the stromal tissue.
[0004] HSF1 itself is not an oncogene, but a broad range of cancer cells have a "nononcogene addiction" to the pro-survival, pro-proliferative, pro-invasive and pro-metastatic functions of HSFI. Indeed, in melanoma, breast, hepatocellular carcinoma, prostate cancer and other cancers, HSFI levels, and in particular nuclear HSFI levels, inversely correlate with patient survival. In melanoma and other cancers, HSFI protein levels are dramatically elevated, in part due to decreased levels of the F Box protein Fbxw7, which normally targets HSFI for ubiquitin-mediated proteasomal degradation. Other mechanisms underlying the increase in HSFI levels and activity, and particularly increased nuclear HSFI levels, in a broad range of cancers are possible. Moreover, silencing of HSFI expression by RNAi, shRNA, CRISPR-Cas9 or inactivation of the HSFI gene by deletion in cultured cancer cells in vitro, or in mice, results in a marked reduction in cancer cell invasion and metastasis and in increased survival of mouse cancer models. While numerous reports have indicated thatHSF1 is a promising therapeutic target in cancer, HSF1 inhibitors are not available for use in the clinic. Therefore, there exists a need to identify novel HSF1 inhibitors.SUMMARY OF THE INVENTION

Each carrier must be "acceptable" in the sense that it is compatible with the other ingredients of the formulation and not injurious to the subject.
[0088] Contemplated formulations include those suitable oral, parenteral (including subcutaneous, intramuscular, intravenous and intradermal) and pulmonary administration. In some embodiments, formulations are conveniently presented in unit dosage form and are prepared by any method known in the art of pharmacy. Such methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association (e.g„ mixing) the active ingredient with liquid carriers or finely divided solid carriers or both, and then if necessary, shaping the product.
[0089] Formulations of the present disclosure suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets, wherein each preferably contains a predetermined amount of the active ingredient; as a powder or granules; as a solution or suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or awater-in-oil liquid emulsion. In other embodiments, the active ingredient is presented as a bolus, electuary, or paste, etc.
[0090] In some embodiments, tablets comprise at least one active ingredient and optionally one or more accessory agents / carriers are made by compressing or molding the respective agents. In some embodiments, compressed tablets are prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder (e.g., povidone, gelatin, hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (e.g., sodium starch glycolate, cross-linked povidone, cross-linked sodium carboxymethyl cellulose) surface-active or dispersing agent. Molded tablets are made by molding in a suitable machine a mixture of the powdered compound (e.g., active ingredient) moistened with an inert liquid diluent. Tablets may optionally be coated or scored and may be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile. Tablets may optionally be provided with an enteric coating, to provide release in parts of the gut other than the stomach.
[0091] Formulations suitable for parenteral administration include aqueous and non-aqueous isotonic sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents, and liposomes or other microparticulate systems which are designed to target the compound to blood components or one or more organs. In some embodiments, the formulations are presented / formulated in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.
[0092] Preferred unit dosage formulations are those containing a daily dose or unit, daily subdose, as herein above-recited, or an appropriate fraction thereof, of an agent. It should be understood that in addition to the ingredients particularly mentioned above, the formulations of this invention may include other agents conventional in the art having regard to the type of formulation in question, for example, those suitable for oral administration may include such further agents as sweeteners, thickeners and flavoring agents.

In some embodiments, the cancer is leukemia.
[0099] Effective amounts of a compound, composition and / or pharmaceutical formulation as provided herein can be determined by a physician with consideration of individual differences in age, weight, tumor size, extent of infection or metastasis, and condition of the patient (subject). The compositions may also be administered multiple times at these dosages. The optimal dosage and treatment regime for a particular patient can readily be determined by one skilled in the art of medicine by monitoring the patient for signs of disease and adjusting the treatment accordingly.
[0100] In some embodiments, the compound of the present disclosure may be administered at a concentration from about 1 mg / kg body weight of the subject to about 20 mg / kg body weight of the subject. For example, the compound of the present disclosure may be administered at a concentration from about 1 mg / kg to about 2 mg / kg, about 1 mg / kg to about 4 mg / kg, about 1 mg / kg to about 6 mg / kg, about 1 mg / kg to about 8 mg / kg, about 1 mg / kg to about 10 mg / kg, about 1 mg / kg to about 12 mg / kg, about 1 mg / kg to about 14 mg / kg, about 1 mg / kg to about 16 mg / kg, about 1 mg / kg to about 18 mg / kg, about 1 mg / kg to about 20 mg / kg, about 2 mg / kg to about 20 mg / kg, about 4 mg / kg to about 20 mg / kg, about 6 mg / kg to about 20 mg / kg, about 8 mg / kg to about 20 mg / kg, about 10 mg / kg to about 20 mg / kg, about 12 mg / kg to about 20 mg / kg, about 14 mg / kg to about 20 mg / kg, about 16 mg / kg to about 20 mg / kg, about 18 mg / kg to about 20 mg / kg, about about 5 mg / kg to about 15 mg / kg, about 5 mg / kg to about 10 mg / kg, or about 10 mg / kg to about 15 mg / kg. In some additional examples, the compound of the present disclosure may be administered at a concentration of about 1 mg / kg, about 2 mg / kg, about 3 mg / kg, about 4 mg / kg, about 5 mg / kg, about 6 mg / kg, about 7 mg / kg, about 8 mg / kg, about 9 mg / kg, about 10 mg / kg, about 11 mg / kg, about 12 mg / kg, about 13 mg / kg, about 14 mg / kg, about 15 mg / kg, about 16 mg / kg, about 17 mg / kg, about 18 mg / kg, about 19 mg / kg, or about 20 mg / kg.
[0101] It is contemplated that the compounds, compositions and / or pharmaceutical formulations of the disclosure can be administered to subjects or individuals susceptible to or at risk of developing pathological growth of target cells and correlated conditions (e.g., at risk of developing a cancer). When the compounds, compositions and / or pharmaceuticalformulations is administered to a subject such as a mouse, a rat or a human patient, the compounds, compositions and / or pharmaceutical formulations can be added to a pharmaceutically acceptable carrier and / or excipient and systemically administered to the subject. To determine patients that can be beneficially treated, a tissue sample may be removed from the patient and the cells assayed for sensitivity to the agent.
[0102] The compounds, compositions and / or pharmaceutical formulations may be administered orally, intranasally, parenterally or by inhalation therapy, and may take the form of tablets, lozenges, granules, capsules, pills, ampoules, suppositories or aerosol form. They may also take the form of suspensions, solutions and emulsions of the active ingredient in aqueous or non-aqueous diluents, syrups, granulates or powders. In addition to an agent of the present invention, the pharmaceutical formulations may also contain other pharmaceutically active compounds or a plurality of compounds of the invention.
[0103] More particularly, a compound, composition and / or pharmaceutical formulation according to the present disclosure, also referred to herein as the active ingredient, may be administered for therapy by any suitable route including, but not limited to, oral, parenteral (including, but not limited to, subcutaneous, intramuscular, intravenous and intradermal) and pulmonary. It is also appreciated that the preferred route varies with the condition and age of the recipient, and the disease being treated. Preferably, the administration is performed orally, intravenously, or via inhalation.
[0104] Ideally, the compounds, compositions and / or pharmaceutical formulations should be administered to achieve peak concentrations of the active compound at sites of disease. This may be achieved, for example, by the intravenous injection of the agent, optionally in saline, or orally administered, for example, as a tablet, capsule or syrup containing the active ingredient.
[0105] Desirable blood levels of the composition may be maintained by a continuous infusion to provide a therapeutic amount of the active ingredient within disease tissue. The use of operative combinations is contemplated to provide therapeutic combinations requiring a lower total dosage of each component agent than may be required when each individual therapeutic compound or drug is used alone, thereby reducing adverse effects.
[0106] Therapeutic amounts are empirically determined and vary with the pathology being treated, the subject being treated and the efficacy and toxicity of the compounds, compositions and / or pharmaceutical formulations. When delivered to an animal, the method isuseful to further confirm efficacy of the compounds, compositions and / or pharmaceutical formulations.
[0107] In some embodiments, in vivo administration is effective in one dose, continuously or intermittently throughout the course of treatment. Methods of determining the most effective means and dosage of administration are well known to those of skill in the art and vary with the composition used for therapy, the purpose of the therapy, the target cell being treated, and the subject being treated. Single or multiple administrations are carried out with the dose level and pattern being selected by the treating physician.
[0108] An effective amount of the compounds, compositions and / or pharmaceutical formulations described herein may be given in one dose, but is not restricted to one dose. Thus, the administration can be two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, or more, administrations of the composition. Where there is more than one administration in the present methods, the administrations can be spaced by time intervals of one minute, two minutes, three, four, five, six, seven, eight, nine, ten, or more minutes, by intervals of about one hour, two hours, three, four, five, six, seven, eight, nine, ten, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 hours, and so on. In the context of hours, the term "about" means plus or minus any time interval within 30 minutes. The administrations can also be spaced by time intervals of one day, two days, three days, four days, five days, six days, seven days, eight days, nine days, ten days, 11 days, 12 days, 13 days, 14 days, 15 days, 16 days, 17 days, 18 days, 19 days, 20 days, 21 days, and combinations thereof. The methods of the present disclosure are not limited to dosing intervals that are spaced equally in time, but encompass doses at nonequal intervals, such as a priming schedule consisting of administration at 1 day, 4 days, 7 days, and 25 days, just to provide a non-limiting example.
[0109] An effective amount for a particular subject / patient may vary depending on factors such as the condition being treated, the overall health of the patient, the route and dose of administration and the severity of side effects. Guidance for methods of treatment and diagnosis is available (see, e.g., Maynard, et al.

In this context, the term "about" means plus or minus one day, plus or minus two days, plus or minus three days, plus or minus four days, plus or minus five days, plus or minus six days, or plus or minus seven days.
[0114] The present disclosure also includes methods involving co-administration of the compounds, compositions and / or pharmaceutical formulations described herein with one or more additional active agents (e.g., additional chemotherapeutic / anti -cancer agents, biological agents, chemical agents, radiation, and the like). Methods for co-administration with an additional therapeutic agent are well known in the art (Hardman, et al. (eds.) (2001) Goodman and Gilman's The Pharmacological Basis of Therapeutics, 10th ed., McGraw-Hill, New York, N.Y.; Poole and Peterson (eds.) (2001) Pharmacotberapeutics for Advanced Practice:A Practical Approach, Lippincott, Williams & Wilkins, Phila., Pa.; Chabner and Longo (eds.) (2001) Cancer Chemotherapy and Biotherapy, Lippincott, Williams & Wilkins, Phila., Pa.).
[0115] In one embodiment, the present disclosure provides methods for enhancing prior art therapies and / or pharmaceutical formulations by co-administering a compound, composition and / or pharmaceutical formulation according to the present disclosure. The pharmaceutical formulations and modes of administration may be any of those described above. In addition, the two or more co-administered chemotherapeutic / anti-cancer agents, chemical agents, biological agents or radiation may each be administered using different modes or different formulations. Co-administration need not refer to administration at the same time in an individual, but rather may include administrations that are spaced by hours or even days, weeks, or longer, as long as the administration of multiple therapeutic agents is the result of a single treatment plan. By way of example, the co-administration may comprise administering the compounds, compositions and / or pharmaceutical formulations according to the present disclosure before, after, or at the same time as the one or more additional therapeutics. In one possible treatment schedule, the compounds, compositions and / or pharmaceutical formulations of the present disclosure may be given as an initial dose in a multi-day protocol, with one or more additional therapeutics given on later administration days; or the one or more additional therapeutics are given as an initial dose in a multi-day protocol, with the compounds, compositions and / or pharmaceutical formulations of the present disclosure given on later administration days. On another hand, one or more additional therapeutic agents and the compounds, compositions and / or pharmaceutical formulations of the present disclosure maybe administered on alternate days in a multi -day protocol. In still another example, a mixture of one or more additional therapeutics and the compounds, compositions and / or pharmaceutical formulations of the present disclosure may be administered to reduce the presence of cancer in the subject. This is not meant to be a limiting list of possible administration protocols.
[0116] Formulations of therapeutic agents may be prepared for storage by mixing with physiologically acceptable carriers, excipients, or stabilizers in the form of, e.g., lyophilized powders, slurries, aqueous solutions or suspensions (see, e.g., Hardman, et al. (2001) Goodman and Gilman's The Pharmacological Basis of Therapeutics, McGraw-Hill, New York, N.Y.; Gennaro (2000) Remington: The Science and Practice of Pharmacy, Lippincott, Williams, and Wilkins, New York, N.Y.; Avis, et al.

[0141] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
[0142] Articles "a" and "an" are used herein to refer to one or to more than one (i.e. at least one) of the grammatical object of the article. By way of example, "an element" means at least one element and can include more than one element.
[0143] " About" is used to provide flexibility to a numerical range endpoint by providing that a given value may be "slightly above" or "slightly below" the endpoint without affecting thedesired result. Unless otherwise noted, “about” may be defined as ± 15% of the endpoint, ± 10% of the endpoint, ± 7% of the endpoint, or ± 5% of the endpoint.
[0144] The use herein of the terms "including," "comprising," or "having," and variations thereof, is meant to encompass the elements listed thereafter and equivalents thereof as well as additional elements. Embodiments recited as "including," "comprising," or "having," certain elements are also contemplated as "consisting essentially of and "consisting of those certain elements. As used herein, "and / or" refers to and encompasses any and all possible combinations of one or more of the associated listed items, as well as the lack of combinations where interpreted in the alternative ("or").
[0145] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. For example, if a concentration range is stated as 1% to 50%, it is intended that values such as 2% to 40%, 10% to 30%, or 1% to 3%, etc., are expressly enumerated in this specification. These are only examples of what is specifically intended, and all possible combinations of numerical values between and including the lowest value and the highest value enumerated are to be considered to be expressly stated in this disclosure.
[0146] Terms used herein may be preceded and / or followed by a single dash, or a double dash, “=”, to indicate the bond order of the bond between the named substituent and its parent moiety; a single dash indicates a single bond and a double dash indicates a double bond or a pair of single bonds in the case of a spiro-substituent. In the absence of a single or double dash it is understood that a single bond is formed between the substituent and its parent moiety; further, substituents are intended to be read “left to right” with reference to the chemical structure referred to unless a dash indicates otherwise. For example, arylalkyl, arylalkyl-, and -alkylaryl indicate the same functionality.
[0147] For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety can refer to a monovalent radical (e.g. CH3-CH2-), in some circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g., -CH2-CH2-), which is equivalent to the term “alkylene.” (Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene). All atoms are understood to have their normal number of valences for bond formation (z.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S).Nitrogens in the presently disclosed compounds can be hypervalent, e.g., an N-oxide or tetrasubstituted ammonium salt. On occasion a moiety may be defined, for example, as -B-(A)a, wherein a is 0 or 1. In such instances, when a is 0 the moiety is -B and when a is 1 the moiety is -B-A.

[0173] The melting temperature (ATm) for purified recombinant human HSF1 (HSF1 DNA binding domain) was determined in the presence of HSF1 degrader compounds shown in Table 1 and compared to the solvent DMSO. Sypro orange dye was added to the HSF1 DBD (5 micromolar final concentration) in buffer, mixed and distributed to wells in 384 well microtiter plates.

Melting curves were obtained and analyzed using the ThermoFisher Shift Software 1.4 fitted with a Boltzmann equation to determine the change in melting temperature of the protein in the presence of DMSO as compared to compound. The difference in the melting temperature under these two conditions was assigned as the change in melting temperature of ATm. Results are shown in Table 2.Table 1

C4-2 prostate cancer cell proliferation at 37°C, 5% CO2 was assessed to determine the IC50 (concentration at which 50% of cell proliferation was inhibited) for each compound. A 9-point dilution series was used to assess the ability of each compound to inhibit the growth of C4-2 prostate cancer cells over a 48-hour period, as compared to negative control solvent, DMSO. Cell proliferation was measured by the Cell Titre Gio assay using 384 well microtiter plate reader to quantitate luminescence. The IC50 was determined from the values obtained.

[0175] Next, the change in heat shock protein gene expression in C4-2 prostate cancer cells was determined. C4-2 prostate cancer cells were grown in RMPI-1640 (no L-glutamine, Gibco 21870076) supplemented with 10% fetal bovine albumin (non-heat-inactivated, Cytiva Hyclone SH30071.03). To quantitatively measure the inhibition of HSF1 activity in C4-2 prostate cancer cells, compounds or DMSO were added to triplicate C4-2 cell cultures for 2 hours. HSF1 activity was then stimulated with the Hsp90 inhibitor SNX-2112 (100 nM) for an additional 5 hr at 37°C in the presence of HSF1 degrader compounds or DMSO. Total RNA was extracted, converted to cDNA and used in qPCR assays to quantify the change in HSF1 target gene transcript expression (HSPA4L equals Hsp70, HSPB1 equals Hsp27 andDNAJB1 equals Hsp40) as compared to GAPDH internal control gene, and then compared to DMSO negative control. The results are shown in Table 2.
[0176] Next, the microsome stability in rats was determined for select compounds from Table 1. Test compounds are incubated with rat liver microsomes supplemented with cofactors at 37°C. Typical conditions were a compound concentration of 1 pM and 5 sampling time-points (0, 5, 15, 30 and 45 minutes), in duplicate. At each time-point, the reactions were terminated by the addition of organic solvent. The samples were centrifuged and the parent compound concentration was evaluated by LC-MS / MS measurements. Control compounds were included with well-established stability when incubated with rat microsomes. Multiple time points were used to determine % parent compound remaining at each time point and to calculate the T1 / 2 for each compound in rat liver microsomes. A higher T1 / 2 indicates increased compound stability in microsomes.
