Abstract
Description
[Technical Field]
[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 63 / 209,682, filed June 11, 2021, the contents of which are incorporated herein by reference in their entirety.
[0002] FIELD OF THE INVENTION This application relates generally to combination therapy of MCL-1 inhibitors with anti-cancer agents. [Background technology]
[0003] Apoptosis (programmed cell death) is a process for eliminating unwanted or potentially dangerous cells from an organism. Evasion of apoptosis is important for the development and sustained growth of tumors. Myeloid cell leukemia 1 protein (MCL-1; also abbreviated as Mcl-1 or MCL1) is an anti-apoptotic member of the Bcl-2 family of proteins. MCL-1 is overexpressed in many cancers. Overexpression of MCL-1 prevents cancer cells from undergoing apoptosis.
[0004] Studies have shown that MCL-1 inhibitors can be used to treat a variety of cancers. See, for example, "The MCL1 inhibitor S63845 is tolerable and effective in diverse cancer models," A. Kotschy et al., Nature, 2016(538):477-482; "Structure Based Design of "Non-Natural Peptidic Macrocyclic Mcl-1 Inhibitors", J.Johannes et al.,ACS Med.Chem.Lett.,2017,8(2):239-244&ACS Med.Chem.Lett.,2017,8(11):1204;"Synergistic action of the MCL-1 inhibitor S63845 with current therapies in preclinical models of triple-negative and HER2-amplified breast cancer", D.Merino et al.,Sci.Transl.Med.,2017 Aug.2,9(401):eaam7049;"Discovery of Mcl-1-specific inhibitor AZD5991 and preclinical activity in multiple myeloma "AMG 176,a Selective MCL1 Inhibitor,Is Effective in Hematologic Cancer Models Alone and in Combination with Established Therapies", S.Caenepeel et al.,Cancer Discov.,2018 Dec 8(12):1582-1597; "Discovery of S64315, a Potent and Selective Mcl-1 Inhibitor", Z. Szlavik at al., J. Med. Chem., 2020, 63(22): 13762-13795. There remains a need to provide more effective methods for the treatment of cancer. [Prior art documents] [Non-patent literature]

[0013] definition Unless the context requires otherwise, throughout this specification and claims, the word "comprise" and variations thereof, e.g., "comprises" or "comprising" are intended to be used in an open and inclusive sense, i.e., "including but not limited to." should be interpreted.
[0014] "C u~v ", i.e. (C u ~C v A prefix such as "C" indicates that the following group has u to v carbon atoms, where u and v are integers. 1~6 "Alkyl" indicates that the alkyl group has from 1 to 6 carbon atoms.
[0015] A dash ("-") that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, -C(O)NH2 is attached through the carbon atom. Dashes at the front or end of a chemical group are for convenience, and chemical groups may be depicted with or without one or more dashes without losing their ordinary meaning. Unless chemically or structurally required, no directionality is indicated or implied by the order in which chemical groups are written or named.
[0016] The term "substituted" means that one or more hydrogen atoms on a hydrocarbon have been replaced with one or more atoms or groups other than hydrogen, provided that the normal valence of the designated carbon atom is not exceeded. A "substituent" is an atom or group that replaces a hydrogen atom on a hydrocarbon when "substituted." Unless otherwise specified, if a group is described as optionally substituted, any substituents of the group are themselves unsubstituted.
[0017] Reference herein to "about" a value or parameter includes (and describes) embodiments that relate to the value or parameter itself. In certain embodiments, the term "about" includes the stated amount ±10%. In other embodiments, the term "about" includes the stated amount ±5%. In certain other embodiments, the term "about" includes the stated amount ±1%. Also, for that term, "about X" includes the description of "X." Additionally, the singular forms "a" and "the" include plural references unless the context clearly indicates otherwise.

As used herein, heteroaryl refers to heteroaryls having 5 to 20 ring atoms (i.e., 5-20 membered heteroaryls), 5 to 12 ring atoms (i.e., 5-12 membered heteroaryls), or 5 to 10 ring atoms (i.e., 10-12 membered heteroaryls). Heteroaryl groups include aryl, ...
[0024] The terms "heterocyclyl," "heterocycle," or "heterocyclic" refer to a monoradical or diradical saturated or unsaturated group having a single ring or multiple fused rings with one or more heteroatoms selected from nitrogen, sulfur, phosphorus, and / or oxygen within the ring. The heteroatoms within a "heterocyclyl" can be oxidized, e.g., -N(O)-, -S(O)-, -S(O)2-. A heterocyclyl can be monocyclic or polycyclic, and the polycyclic rings can be fused, bridged, or spiro.
[0025] "Isomers" are different compounds that have the same molecular formula. Isomers include stereoisomers, enantiomers, and diastereomers.
[0026] "Stereoisomers" refer to compounds made up of the same atoms connected by the same bonds but with different, not interchangeable, three-dimensional structures.

[0032] As used herein, "treatment" or "treating" is an approach for obtaining a beneficial or desired result. For purposes of this disclosure, beneficial or desired results include, but are not limited to, alleviating symptoms and / or reducing the symptoms associated with a disease or condition. In one embodiment, "treatment" or "treating" includes one or more of: a) inhibiting a disease or condition (e.g., reducing one or more symptoms resulting from a disease or condition and / or reducing the severity of the disease or condition); b) delaying or halting the onset of one or more symptoms associated with a disease or condition (e.g., stabilizing the disease or condition, slowing the worsening or progression of the disease or condition); and c) alleviating the disease or condition, e.g., regressing clinical symptoms, improving the disease state, slowing disease progression, increasing quality of life, and / or prolonging survival.
[0033] As used herein, "prevention" or "preventing" refers to a regimen that protects against the onset of a disease or disorder, such that clinical symptoms of the disease or disorder do not develop. Thus, "prevention" relates to the administration of a treatment to a subject before symptoms of the disease are detectable in the subject. The subject may be an individual at risk of developing a disease or disorder, such as an individual with one or more risk factors known to be associated with the onset or development of a disease or disorder.
[0034] As used herein, the term "therapeutically effective amount" or "effective amount" refers to an amount effective to elicit a desired biological or medical response when administered to a subject to treat a disease, including an amount of an agent sufficient to effect such treatment of the disease. The effective amount will vary depending on the particular agent and characteristics of the treated subject, such as age, weight, etc. An effective amount can include a range of amounts. As understood in the art, an effective amount can be one or more doses, i.e., a single dose or multiple doses may be required to achieve a desired therapeutic endpoint. An effective amount may be considered in relation to the administration of one or more therapeutic agents, and a single agent may be considered to be administered in an effective amount when a desired or beneficial result can be or is achieved in combination with one or more other agents. The appropriate dose of any co-administered agent may optionally be reduced due to the combined action (e.g., additive or synergistic) of the agents.
[0035] As used herein, "co-administration" includes administering a unit dose of an agent disclosed herein before or after administering a unit dose of one or more additional therapeutic agents, e.g., administering an agent disclosed herein within seconds, minutes, or hours of administering one or more additional therapeutic agents. For example, in some embodiments, a unit dose of an agent disclosed herein is administered first, followed within seconds or minutes by a unit dose of one or more additional therapeutic agents. Alternatively, in other embodiments, a unit dose of one or more additional therapeutic agents is administered first, followed within seconds or minutes by a unit dose of a compound disclosed herein. In some embodiments, a unit dose of a compound disclosed herein is administered first, followed several hours (e.g., 1-12 hours) later by a unit dose of one or more additional therapeutic agents. In other embodiments, a unit dose of one or more additional therapeutic agents is administered first, followed several hours (e.g., 1-12 hours) later by a unit dose of a compound disclosed herein.
[0036] Administration "in combination with" one or more further therapeutic agents includes simultaneous (concurrent) and sequential or sequential administration in any order.
[0037] The term "concurrently" is used herein to refer to the administration of two or more therapeutic agents, where at least a portion of the administration overlaps in time, or the administration of one therapeutic agent is within a short period of time relative to the administration of another therapeutic agent, e.g., the two or more therapeutic agents are administered within a certain time interval of no more than a certain number of minutes.
[0038] The term "sequentially" is used herein to refer to the administration of two or more therapeutic agents, where the administration of one or more agents continues after the administration of one or more other agents is discontinued, or where the administration of one or more agents begins before the administration of one or more other agents, e.g., where the two or more therapeutic agents are administered at intervals of more than a certain number of minutes.
[0039] As used herein, "in conjunction with" refers to the administration of one therapeutic modality in addition to another therapeutic modality. Thus, "in conjunction with" refers to the administration of one therapeutic modality before, during, or after the administration of another therapeutic modality to an individual.
[0040] The term "conjugate" or "antibody-drug conjugate" refers to an antibody that is chemically linked to a second chemical moiety, such as a therapeutic or cytotoxic agent. includes a chemical compound, a mixture of chemical compounds, a biological macromolecule, or an extract made from biological materials. In some embodiments, therapeutic or cytotoxic agents include, but are not limited to, pertussis toxin, taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicine, doxorubicin, daunorubicin, dihydroxyanthracin dione, mitoxantrone, mithramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, and puromycin, and analogs or homologs thereof. When used in the context of an immunoassay, the conjugated antibody can be a detectably labeled antibody used as a detection antibody.
[0041] "Intravenous administration" is the administration of a substance into a vein or "into a vein." Compared to other routes of administration, the intravenous (IV) route is a more common method for delivering fluids and medications throughout the body. It is a faster method. Infusion pumps can allow precise control over the flow rate and total amount of medication delivered. However, if changes in flow rate do not have serious consequences or a pump is not available, the infusion is often left to flow by simply placing the bag above the patient's level and adjusting the rate using a clamp. Alternatively, if the patient requires a high flow rate and the IV access device is large enough in diameter to accommodate it, a rapid infuser can be used. This is either an inflatable cuff placed around the fluid bag to force the fluid into the patient, or a similar electrical device that can also heat the infused fluid. If the patient only needs medication at a specific time, an intermittent infusion is used, which does not require additional fluid. This can use the same technique as an intravenous infusion (pump or gravity infusion), but after the full dose of medication is given, the tubing is disconnected from the IV access device. Some medications are also given by IV push or bolus; that is, a syringe is connected to the IV access device and the medication is injected directly (or slowly, if this stimulates the vein or causes a rapid effect). When a medication is injected into the fluid stream of an IV tubing, there must be some means to ensure that it reaches the patient through the tubing. Typically, this is accomplished by allowing the fluid stream to flow normally, thereby carrying the medication into the bloodstream. However, a second fluid injection is sometimes used after the injection as a "washout" to allow the medication to flow more quickly into the bloodstream. Thus, in one embodiment, the agent(s) or combination of agents described herein may be administered by IV administration, either alone or in combination with administration of specific components of the treatment regimen by oral or parenteral routes.
[0042] "Oral administration" means a route of administration in which a substance is taken through the mouth, and includes buccal, sublabial, and sublingual administration, as well as enteral administration and administration through the respiratory tract, unless the drug is in direct contact with any of the oral mucosa, e.g., via a tube. Typical forms for oral administration of therapeutic agents include the use of tablets or capsules. Thus, in one embodiment, a compound(s) or combination of compounds described herein may be administered by the oral route, either alone or in combination with administration of certain components of the treatment regimen by IV or parenteral routes.
[0043] Also provided herein are pharmaceutically acceptable salts, hydrates, solvates, tautomers, polymorphs, and prodrugs of the compounds of Formula (I) described herein. "Pharmaceutically acceptable" or "physiologically acceptable" refers to compounds, salts, compositions, dosage forms, and other materials that are suitable for use in human medicine.
[0044] The compounds of formula (I) described herein may be prepared and / or formulated as pharmaceutically acceptable salts. Pharmaceutically acceptable salts are non-toxic salts of the free base form of the compounds that possess the desired pharmacological activity of the free base. These salts may be prepared from inorganic or organic acids or from inorganic or organic acids. Pharmaceutically acceptable salts may be derived from inorganic bases. For example, compounds containing a basic nitrogen can be prepared as pharmaceutically acceptable salts by contacting the compound with an inorganic or organic acid. Non-limiting examples of pharmaceutically acceptable salts include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, monohydrogen phosphate, dihydrogen phosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, propionate, decanoate, caprylate, acrylate, formate, isobutyrate, caproate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, butyne-1,4-dioate, hexyl phosphate ...

[Example]
[0120] Example 1: In vitro synergy of MCL-1 inhibitors with SN-38 in TNBC and NSCLC cell lines To test the potential for combination between Compound A and SN-38 (a topoisomerase inhibitor), in vitro studies were conducted in a panel of triple-negative breast cancer (TNBC, n=3) and non-small cell lung cancer (NSCLC, n=2) cell lines using the Bliss independence model of synergy. Cells were exposed to a dose-titrated matrix of each compound alone and in combination for 72 hours, and cell viability was then determined by Cell Titer Glo reagent. Strong Bliss synergy scores (>100) were observed in all cell lines tested. Materials and Methods Cell culture and reagents
[0121] HCC70 (ATCC® CRL-2315), HCC1806 (ATCC® CRL-2335), HCC1187 (ATCC® CRL-2322), NCI-H522 (ATCC® CRL-5810), and H820 (ATCC® HTB-181) cell lines were thawed from liquid nitrogen storage and maintained in RPMI-1640 (Gibco-12633) + 10% HI-FBI (Gibco-16140) + Pen / Strep (100x Gibco-15140) according to ATCC guidelines. Cells were passaged using 0.25% trypsin / EDTA (1x GIBCO-25200) according to ATCC guidelines.
[0122] SN-38 and Compound A stocks (provided by the Gilead sample bank) were dispensed directly into treatment wells using a D300e Digital Dispenser (vendor) with DMSO (Sigma-D2438) to 0.1% v / v as a vehicle control.
[0123] Viability assessment was performed using Cell Titer Glo™ (Promega #G9241) according to the manufacturer's microwell plate protocol and read for luminescence on a Biotek Synergy Neo2 plate reader. Cell viability combination assay
[0124] For the synergy matrix assay, cell lines were seeded at 5,000 cells per well in clear-bottom white 96-well plates (Corning #3909) in 100 μL of the recommended cell culture medium. Treatment maps consisted of a single-agent dose response for Compound A (seven 3-fold dilutions + no-treatment control) or SN-38 (nine 3-fold dilutions + no-treatment control) and a checkerboard matrix of 63 different combinations. Concentration ranges were selected based on the relative sensitivity of each cell line to the compounds. Five plates were used for each combination to generate sufficient replicates to calculate synergy scores with 95% confidence intervals (95% CI).
[0125] Compounds and DMSO vehicle were applied to cells using an HP D300 dispenser and dispensed directly into the medium according to a checkerboard matrix, and viability was measured by Cell Titer Glo after 72 hours of incubation at 37°C / 5% CO2 / 100% relative humidity. Data analysis
[0126] Combination viability data were evaluated for synergy using the Excel template described by Prichard and Shipman {Prichard 1990}. Specifically, the single-component dose curves for SN-38 and Compound A were normalized to the percent viability on each plate and averaged across five technical replicates to calculate the theoretical additive kill of the combination according to the Bliss principle of independence. Calculated values were compared with experimental results generated using a 63-concentration checkerboard. Synergy or antagonism scores were generated depending on whether the observed growth inhibition was greater or less than the calculated value, respectively.
[0127] For example, if two compounds (B) and (C) at given concentrations each produce 60% inhibition, their theoretical additive inhibition will be 84% according to the Bliss independence formula: 60% B +60% C * (100%-60% B )=84% B+C If the experimental result is greater than the calculated value (e.g., 90% inhibition), the difference [6%] is added to the synergy score. If the result is less (e.g., 78% inhibition), the difference [6%] is added to the antagonism score.
[0128] These differences were summed across the entire checkerboard (63 wells) to obtain cumulative synergy and antagonism scores in μM 2 The scores were given in %, reflecting a 2D surface of the dose-response. A 95% confidence interval adjustment was applied to the synergy and antagonism scores, and each sum was compared to the original scale: a score above 50 was considered moderate synergy, and a score above 100 was considered strong synergy, likely indicating a combined effect in vivo. {Prichard 1990}.
[0129] Data from combination assays are presented in three formats. Synergy scores with 95% confidence intervals were averaged from n=2 assays. Exemplary tabular and graphical formats for each cell line. Percent inhibition matrix of Example tabular and graphical synergy matrices with 95% confidence intervals for each cell line.
[0130] To test the potential for combination between Compound A and SN-38 (a topoisomerase inhibitor), in vitro studies were conducted in a panel of TNBC (n=3) and NSCLC (n=2) cell lines using the Bliss independence model of synergy. Cells were exposed to a dose-titrated matrix of each compound alone and in combination for 72 hours, and cell viability was then determined using Cell Titer Glo reagent. Strong Bliss synergy scores (>100) were observed in all cell lines tested.

Paclitaxel was incubated for 4 hours, then washed off by removing the medium, washing twice with 200 μL of prewarmed complete medium, and finally replacing with 100 μL of prewarmed complete medium. Cells were then exposed to Compound A in the same checkerboard matrix using the D300 dispenser and incubated for 48 hours before measuring viability by Cell Titer Glo. MSD assay
[0139] For the MSD assay, TNBC cell lines were seeded at 25,000 cells per well in clear-bottom white 96-well plates (Corning #3909) in the recommended cell culture medium. Plates were incubated at 37°C and 100% RH for 20 hours before compound exposure. Paclitaxel and DMSO vehicle were first applied to the cells using an HP D300 dispenser and aliquoted directly into the medium. Paclitaxel was incubated for 4 hours, then washed away by removing the medium, washing twice with 150 μL of prewarmed complete medium, and finally replacing with 100 μL of prewarmed complete medium. After an additional 20 hours, samples were collected by aspirating the supernatant, and 125 μL of 1× lysis buffer was added to each well. Plates were briefly placed on ice and transferred to a rocking platform at 4°C for 20 minutes. Plates were placed on dry ice, flash-frozen for 10 minutes, and then stored at -80°C until testing.
[0140] MCL1 and MCL1-BAK and MCL1-BIM dimer assays were performed using materials and protocols provided by MSD Custom Assay Services based on their U-Plex technology. Plates were first prepared using the standard U-PLEX capture antibody coating protocol and then washed three times with 150 μL of MSD wash buffer. 25 μl of sample or standard was added directly to the plate, which was then sealed and incubated at room temperature for 1 hour with shaking. The plate was washed three times with 150 μL of wash buffer per well, and 50 μL of antibody detection solution was added to each well of the MSD plate. The plate was sealed and incubated at room temperature for 1 hour with shaking. The plate was again washed three times with 150 μL of wash buffer per well. 150 μL of 2x read buffer was added to each well, and the plate was read on an MSD SECTOR Imager 2400.
[0141] The GAPDH assay kit (MSD) was run according to the manufacturer's protocol, using 25 μL of lysate per sample added directly to the plate.

Simple Western
[0142] Simple Western immunoassays are performed in capillaries. Samples and reagents are loaded into an assay plate and placed in the Protein Simple Instrument. Cell lysates are automatically loaded into the capillaries and separated by size as they migrate through a stacking and separation matrix. Separated proteins are then immobilized to the capillary wall via a proprietary light-activated capture chemistry. Target proteins are identified using a primary antibody and immunoprobed with an HRP-conjugated secondary antibody and a chemiluminescent substrate. The resulting chemiluminescent signal is detected and quantified.
[0143] FBXW7 expression was measured in cell lines after 4 hours of treatment with 1 μM paclitaxel, followed by washing and overnight incubation using Simple Western. Lysates were prepared and diluted to 0.5 μg / ml in 1× lysis buffer. The Simple Western platform is run on a 384-well plate.
[0144] The marker, internal ladder, and DTT are provided in lyophilized form by Simple Western. Resuspend the reagents as described in the protocol. Add 20 μL of water to the marker. Add 40 μL of water to the DTT, and mix 20 μL of 10X sample buffer and 20 μL of DTT. This is referred to as Z buffer. Load the marker into well 1A. Add 5 μL of lysate to a 1.7 mL Eppendorf tube. Add 1.2 μL of Z reagent to each sample. Heat the samples at 100°C for 5 minutes, cool, and then spin in a microcentrifuge for 30 seconds. Load the samples into wells A2-12. Dilute the primary antibody 1:50 in antibody dilution buffer (6 μL + 294 μL dilution buffer). Load 20 μL of each antibody into lanes 2-12. Each row can contain up to eight different antibodies. Actin diluted 1:300 was used as a loading control. Further loading of either goat anti-rabbit or goat anti-mouse secondary antibody is performed as needed. The plate is rotated at 2.6k for 10 minutes at room temperature, loaded onto the instrument, and run overnight. Target proteins are identified using primary antibodies and immunoprobed using HRP-conjugated secondary antibodies and a chemiluminescent substrate. The resulting chemiluminescent signal is detected and quantified. Data analysis About Bliss Synergy
[0145] Combination viability data were evaluated for synergy using the Excel template described by Prichard and Shipman {Prichard 1990}. Specifically, the single-component dose curves for paclitaxel and Compound A were normalized to the percent viability on each plate and averaged across five technical replicates to calculate the theoretical additive kill of the combination according to the Bliss principle of independence. Calculated values were compared to experimental results generated with a 63-concentration checkerboard. Synergy or antagonism scores were generated depending on whether the observed growth inhibition was greater or less than the calculated value, respectively.
[0146] For example, if two compounds (B) and (C) at given concentrations each produce 60% inhibition, their theoretical additive inhibition will be 84% according to the Bliss independence formula: 60% B +60% C * (100%-60% B )=84% B+C
[0147] If the experimental result is greater than the calculated value (e.g., 90% inhibition), the difference [6%] is added to the synergy score. If the result is less (e.g., 78% inhibition), the difference [6%] is added to the antagonism score.
[0148] These differences were summed across the entire checkerboard (63 wells) to obtain cumulative synergy and antagonism scores in μM 2 The scores were given in %, reflecting a 2D surface of the dose-response. A 95% confidence interval adjustment was applied to the synergy and antagonism scores, and each sum was compared to the original scale: a score above 50 was considered moderate synergy, and a score above 100 was considered strong synergy, likely indicating a combined effect in vivo. {Prichard 1990}.

[0150] For total MCL1, ECL signals were recorded and converted to pg / mL using calibration controls developed at MSD over an eight-point standard dose range (0-10,000 pg / mL) using a four-parameter curve-fitting function in MSD WorkBench software. Results for MCL1-BAK and MCL1-BIM dimers were converted to pg / mL using the same process, except standard concentrations ranged from 0-50,000 pg / mL. GAPDH results were recorded and reported as ECL and used to normalize both MCL1 and MCL1 dimer within each sample set. For graphical comparisons between analytes for a given cell line, each pg / mL data set was normalized to the vehicle control at 100%, with no protein at 0%.
[0151] Paclitaxel has been reported to downregulate MCL1 protein levels, in part through an increase in the MCL1 E3-ligase FBXW7, which targets MCL1 for proteasomal degradation {Wertz 2011}. To confirm this observation, HCC70, MDA-MB-468, and HCC1806 TNBC cell lines were treated with a clinically relevant concentration of paclitaxel (1 μM) for 4 hours (Gianni 1995). After paclitaxel treatment, cells were incubated overnight, and protein levels were determined. Comparison of paclitaxel treatment with vehicle control revealed increased FBXW7 protein levels and decreased MCL1 protein levels (Table 13 and Figure 1). Paclitaxel treatment also resulted in decreased protein levels of MCL1-BAK and MCL1-BIM dimers (Table 13 and Figure 1). These results were observed across all three TNBC cell lines (n = 3 biological replicates).
[0152] HCC70, MDA-MB-468, and HCC1806 TNBC cell lines were treated with a clinically relevant concentration of paclitaxel (1 μM) for 4 hours (Gianni 1995). Paclitaxel treatment increased FBXW7 protein levels, decreased MCL1 protein levels, and decreased MCL1-BAK and MCL1-BIM dimer protein levels in all three cell lines. HCC70, MDA-MB-468, and HCC1806 were treated with paclitaxel dose-escalation (protein-adjusted C). max Bliss synergy (>100) was observed when mice were pretreated with 100 μM of Compound A (including 1 μM) for 4 hours to mimic clinical exposure, followed by 72 hours of exposure to increasing doses of Compound A. [Table 13] a Mean normalized protein levels (n = 3 biological replicates)
[0153] Bliss synergy was used to determine whether the reduction in MCL1 protein levels after paclitaxel treatment resulted in enhanced sensitivity to Compound A. HCC70, MDA-MB-468, and HCC1806 were treated with paclitaxel dose escalation (protein-adjusted C). max = 1 μM) for 4 hours to mimic clinical exposure and then exposed to increasing doses of Compound A. Cells were incubated for 72 hours and viability was determined using the CTG reagent. Bliss synergy was observed across all three TNBC cell lines exposed to the combination of Compound A and paclitaxel in vitro (Table 15). A Bliss synergy score of greater than 100 is considered a strong effect {Prichard 1990}. [Table 14] [Table 15] [Table 16] [Table 17] [Table 18] [Table 19] [Table 20] Example 3: The potential combination of Compound A with targeted agents and chemotherapy was tested in a panel of breast cancer cell lines using a 72-hour in vitro proliferation assay. The results of the combination studies are shown in Table 21. [Table 21-1] [Table 21-2] [Table 21-3] [Table 21-4] [Table 21-5] [Table 21-6] [Table 21-7] [Table 21-8] [Table 21-9] [Table 21-10] [Table 21-11] [Table 21-12] [Table 21-13] [Table 21-14] [Table 21-15] [Table 21-16] [Table 21-17] [Table 21-18] Example 4: The potential combination of Compound A with BTK inhibitors was tested in a panel of hematological cancer cell lines using a 72-hour in vitro proliferation assay. The results of the combination study are shown in Table 22. [Table 22] Example 5: Combination potential of Compound A and SN-38 was assessed using a 72-hour in vitro proliferation assay The combination assay was used to test a panel of TNBC and NSCLC cancer cell lines. The results of the combination studies are shown in Table 23. [Table 23] Example 6: The potential combination of Compound A and paclitaxel was tested in an in vivo TNBC PDX model in an antitumor efficacy study (Figures 5 and 6). Example 7: Phase 1a / b Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Compound A as Monotherapy and in Combination with Anticancer Therapy in Subjects with Solid Malignancies
[0154] The study will be conducted to characterize the safety and tolerability of Compound A and Compound A in combination with anti-cancer therapy in subjects with advanced solid malignancies. Test Design
[0155] This is an open-label, multicenter, dose-escalation, and dose-expansion Phase 1a / 1b study to evaluate the safety, tolerability, and PK profile of Compound A, document any DLTs (dose-limiting toxicities), and determine the MTD (maximum tolerated dose) and / or RP2D (recommended phase 2 dose) of Compound A as monotherapy and in combination with anticancer therapy in subjects with advanced solid malignancies. The RP2D is the dose level(s) with acceptable tolerability, exposure, efficacy, and biomarker activity. The study consists of two phases: Phase 1a (dose expansion), followed by Phase 1b (dose expansion). Phase 1a Dose Escalation: Part A: Dose Escalation of Compound A as Monotherapy Phase 1b dose expansion: Part B: Optional disease-specific cohorts of Compound A in combination with anti-cancer therapies in parallel with Part A Part C: Safety run-in and expansion of Compound A in combination with anti-cancer therapies following Parts A and B.
[0156] Each part of the study consists of a screening, treatment, and follow-up period. Screening will occur up to 28 days before the first dose of study treatment, during which subject eligibility and baseline characteristics will be determined. Part A: Phase 1a dose escalation of Compound A as monotherapy.
[0157] Subjects with advanced solid tumors who have failed or intolerant to standard therapy, or for which no standard therapy exists, will be sequentially enrolled to receive Compound A as monotherapy at increasingly higher dose levels.
[0158] Dose escalation will be performed using a dose escalation design based on the 3+3 rule.
[0159] Compound A will be administered orally on days 1, 2, 8, 9, 15, and 16 of each 21-day cycle for up to 105 weeks.
[0160] Up to six cohorts (i.e., six dose levels) of 3-6 subjects each will receive escalating dose levels of Compound A as monotherapy. The planned starting dose of Compound A is 5 mg, with target doses of 15 mg and 50 mg for the following two cohorts. Subsequent dose levels following the starting dose will be determined based on safety, tolerability, and PK (pharmacokinetics) data from previous cohorts. The dose level increase will be determined based on all available clinical data, including the clinical status of the patient, and approved by the Safety Review Team (SRT), potentially up to 300 mg. The increase in dose level will be no more than half a logarithm with each subsequent dose escalation.
[0161] The safety and tolerability of each dose level will be assessed by the SRT after all subjects within a cohort have been followed for at least 21 days after the first dose of Compound A or after a subject has a DLT during the first 21 days of study drug administration.
[0162] The first block of each dose consists of three subjects. If no subjects experience a DLT during the first 21 days of study drug administration, dose escalation will occur. If one subject in the initial cohort of three subjects experiences a DLT during the first 21 days of study drug administration, three additional subjects will be enrolled at the same dose level. If no DLT is observed in the three additional subjects, dose escalation will occur. If two or more subjects experience a DLT within the first 21 days, dose de-escalation to a lower dose will occur. The MTD is the highest dose level with a subject incidence of DLT of less than 33% during the first 21 days of study drug administration.
[0163] 21 days of treatment with a consistent regimen in any given cohort for the decision rule to apply.
[0164] Throughout the study, subjects with malignant tumors for which a biopsy is available may undergo optional tumor biopsies. These subjects must consent and provide separate, specific written consent. Dose escalation criteria
[0165] For any given cohort, the sponsor may choose to withhold dosing, select an intermediate dose, or stop study enrollment at any time based on a review of preliminary safety and available PK and / or pharmacodynamic data.
[0166] Based on review of relevant safety and available PK and / or pharmacodynamic data by the SRT, escalation to higher dose cohorts will occur only in the absence of DLTs and / or meeting any pre-specified stopping criteria. Dose escalation to subsequent cohorts on a greater than half-log scale requires affirmation by at least two-thirds of the SRT.
[0167] Dose-limiting toxicities are defined as the following Compound A-related events occurring within the first 21 days (after the first dose of Compound A): Grade 4 hematologic toxicity lasting more than 21 days. All Compound A-related Grade 3 non-hematologic toxicities lasting more than 7 days and all Compound A-related Grade 4 non-hematologic toxicities of any duration will be considered DLTs. Part B: Optional disease-specific cohorts of compound A in combination with anti-cancer therapy in parallel with Part A
[0168] During monotherapy dose escalation in Part A and prior to the formal dose expansion of sponsor-nominated and supported disease-specific cohorts featuring combination therapy with Compound A in Part C, the sponsor may choose to nominate and support one or more of the following cohorts aligned with those in Part C for combination therapy with Compound A at any previously evaluated dose in Part A that was deemed safe and tolerable by the SRT: Cohort B1: Metastatic NSCLC (Compound A + docetaxel) Cohort B2: Metastatic NSCLC (compound A + sacituzumab govitecan) Cohort B3: Metastatic TNBC (Compound A + docetaxel) Cohort B4: Metastatic TNBC (compound A + sacituzumab govitecan) Cohort B5: mSTS with non-specific histology (Compound A + docetaxel and gemcitabine)
[0169] Each additional cohort consists of a single such population with a particular combination. Part C: Safety run-in and dose expansion of Compound A in combination with other anticancer therapies
[0170] This is an open-label Phase 1b study with Compound A given in combination with one or more other anticancer therapies in the following five disease-specific cohorts designated and supported by the sponsor after completion of Parts A and B: Cohort C1: Metastatic NSCLC (Compound A + docetaxel) Cohort C2: Metastatic NSCLC (compound A + sacituzumab govitecan) Cohort C3: Metastatic TNBC (Compound A + docetaxel) Cohort C4: Metastatic TNBC (compound A + sacituzumab govitecan) Cohort C5: mSTS with non-specific histology (Compound A + docetaxel and gemcitabine)
[0171] The RP2D is the dose level(s) with acceptable tolerability, exposure, and biomarker activity.
[0172] The SRT will recommend an initial dose of Compound A for use in combination for each cohort based on the totality of clinical, safety, PK, and pharmacodynamic data. A safety run-in group of at least 3 subjects and no more than 6 subjects will be enrolled to ensure the combination is safe and tolerable in each subject population.
[0173] The safety run-in will employ the same 3+3 design and dose escalation rules as Part A, and will use the same DLT criteria and DLT assessment window as Part A to determine the MTD and / or RP2D. A minimum of 6 subjects must be treated at a dose level before this dose level can be expanded. If cognate disease-specific cohorts from Part B are studied in the RP2D, those subjects may be counted and considered toward the safety run-in group requirements.
[0174] The expansion will include approximately 30 subjects less any disease-specific cognate subjects treated with the same regimens studied in combination under Part B and in any safety run-in. For each disease-specific cohort (B1+C1, B2+C2, B3+C3, B4+C4, B5+C5), a minimum of 20 subjects in RP2D will be enrolled, including any subjects from Part B and / or safety run-in.
