Description

[Technical Field]

[0001] The present invention relates to combinations of specific anti-cancer compounds, and pharmaceutical compositions and kits containing them, for use in the treatment of cancers such as pancreatic, colon and lung cancer. [Background technology]

[0002] KRAS (Kirsten Rat Sarcoma Virus) is a gene that provides instructions for making a protein called K-Ras, which is part of the RAS / MAPK pathway. This protein relays signals from outside the cell to the cell's nucleus. These signals tell the cell to grow and divide (proliferate) or to mature and take on specialized functions (differentiate).

[0003] KRAS mutations have been implicated in a variety of malignancies, including cancers such as lung adenocarcinoma, mucinous adenoma, pancreatic ductal carcinoma, and colorectal cancer. Colorectal cancer is a cancer with a high incidence and mortality rate, with approximately 1.4 million new cases reported annually worldwide (World Cancer Report 2014). While surgery remains the most effective treatment for colorectal cancer, chemotherapy and radiation therapy have also made significant advances in recent years. Large-scale clinical trials conducted primarily in Europe and the United States have demonstrated that combination chemotherapy, which combines several anticancer drugs, is effective against colorectal cancer, contributing to tumor regression and prolonged prognosis (J. Clin. Oncol., 22, pp. 229–237, 2004). In addition to chemotherapy, molecularly targeted drugs such as anti-VEGF (vascular endothelial growth factor) antibodies and anti-EGFR (epidermal growth factor receptor) antibodies are often used in combination with chemotherapy as first-line treatments. Regarding EGFR antibody drugs, it is clear that mutations in the RAS gene are a negative predictor of efficacy (Cancer Res., 66, pp. 3992-3995, 2006), and in colorectal cancer, EGFR antibody drugs are currently only applicable to patients with wild-type RAS genes.

[0004] Additionally, lung cancer accounts for 19% of all cancer deaths, the highest rate, with approximately 1.8 million new cases reported annually worldwide (World Cancer Report 2014). Specifically, non-small cell lung cancer (NSCLC) patients are reported to account for 80-85% of lung cancer cases (American Cancer Society, Cancer Facts and Figures, 2016). While surgical treatment is considered up to a certain stage, chemotherapy and radiation therapy become the secondary treatments. Based on cytomorphology, adenocarcinoma and squamous cell carcinoma are the most common types of NSCLC. While these tumors share a similar clinical course, adenocarcinoma is characterized by its location in the lung periphery.

[0005] Pancreatic cancer, primarily pancreatic ductal adenocarcinoma, has an extremely poor prognosis, with a 5-year survival rate of less than 10% (CA Cancer J.Clin., 2016, 66, pp. 7–30), and approximately 340,000 new cases are reported annually worldwide (GLOBOCAN 2012). The most effective treatment for pancreatic cancer is surgery. However, because early detection is difficult, pancreatic cancer often metastasizes, making it inoperable. In inoperable cases, chemotherapy and radiation therapy are used, but survival rates are poor. Currently, FOLFRINOX therapy (a combination therapy of 5-FU, irinotecan, and oxaliplatin with the addition of levofolinate) is the standard treatment for pancreatic cancer. However, due to its strong toxicity, patients must be carefully selected; for example, this therapy should only be used on patients with an ECOG performance status of 1 or less (J. Clin. Oncol., 2018, 36, pp. 2545-2556). As a molecular targeted drug, the epidermal growth factor receptor (EGFR) inhibitor erlotinib has been approved in combination with gemcitabine. However, the overall survival benefit was only about two weeks compared to gemcitabine alone, and no satisfactory therapeutic effect was achieved.

[0006] RAS proteins are small guanosine triphosphate (GTP)-binding proteins of approximately 21 kDa composed of 188–189 amino acids. RAS proteins include four major types (KRAS (KRAS4A and KRAS4B), NRAS, and HRAS) produced by three genes: KRAS, NRAS, and HRAS. RAS proteins are divided into active GTP-bound and inactive GDP-bound forms. RAS proteins are activated by ligand stimulation of cell membrane receptors, such as EGFR, by replacing guanosine diphosphate (GDP) with GTP. Active RAS binds to up to 20 effector proteins, including RAF, PI3K, and RALGDS, and activates downstream signaling cascades. Meanwhile, active RAS is converted to its inactive form by replacing GTP with GDP through its intrinsic GTP hydrolysis (GTPase) activity. This GTPase activity is enhanced by GTPase-activating proteins (GAPs). As can be seen from the above, RAS plays an important role as a "molecular switch" in intracellular signaling pathways such as EGFR, and plays an extremely important role in processes such as cell growth, proliferation, and angiogenesis (Nature Rev.Cancer, 2011, 11, pp. 761-774; Nature Rev.Drug Discov., 2014, 13, pp. 828-851; Nature Rev.Drug Discov., 2016, 15, pp. 771-785).

[0007] Spontaneous mutations in the RAS gene result in amino acid substitutions that reduce RAS function as a GTPase and its response to GAPs, resulting in a constitutively activated state, which then transmits signals downstream. This excessive signaling can lead to oncogenesis and accelerated cancer growth.

[0008] For example, pancreatic ductal adenocarcinoma (PDA) has been shown to develop through a weakly dysplastic stage followed by a strongly dysplastic stage in pancreatic intraepithelial neoplasia (PanIN). Mutations in the KRAS gene are already present in early-stage PanIN. Subsequently, abnormalities in the tumor suppressor genes INK4A, p53, and SMAD4 lead to malignant progression (Nature Rev. Cancer, 2010, 10, pp. 683-695). Furthermore, mutations in the KRAS gene are present in over 90% of PDA cases, the majority of which are spontaneous point mutations at codon 12 in KRAS exon 2 (Cancer Cell, 2017, 32, pp. 185-203). As can be seen from the previous section, KRAS plays a crucial role in the oncogenesis and development of pancreatic cancer.

[0009] Known mutations in the KRAS gene include the KRAS G12C mutation and the KRAS G12D mutation. The G12C mutation occurs frequently in non-small cell lung cancer, but occurs in a small percentage of pancreatic cancer (Cancer Cell 2014, 25, pp. 272-281). Therefore, therapeutic agents for other KRAS mutations are desired. The G12D mutation is reported to be found in approximately 34% of pancreatic cancer cases, the highest rate among KRAS mutations (Nat. Rev. Cancer 2018, 18, pp. 767-777).

[0010] WO2016 / 049565, WO2016 / 049568 and WO2017 / 172979 disclose certain KRAS inhibitors and state that these agents are useful for cancers with mutations in KRAS codon 12. The G12D mutation is one such mutation, but there is no description of their effects on G12D-mutated KRAS cancers.

[0011] In recent years, bifunctional compounds, collectively known as PROTACs (proteolysis-targeting chimeras) or SNIPERs (specific and nongenetic IAP-dependent protein erasers), have been discovered as a technique for inducing target protein degradation and are expected to become a novel drug discovery modality (Drug.Discov.Today Technol., 2019, 31, pp. 15-27). Such bifunctional compounds promote the formation of a complex between the target protein and an E3 ligase in cells, and the degradation of the target protein is induced using the ubiquitin-proteasome system. The ubiquitin-proteasome system is one of the intracellular protein degradation mechanisms. Proteins called E3 ligases recognize proteins to be degraded and convert them to ubiquitin, thereby promoting degradation by the proteasome.

[0012] More than 600 E3 ligases exist in living organisms, and they can be broadly divided into four types: HECT-domain E3s, U-box E3s, monomeric RING E3s, and multisubunit E3s. Currently, only a limited number of E3 ligases are used as bifunctional degraders, known as PROTACs and SNIPERs. Representative examples include von Hippel-Lindau (VHL), cerebron (CRBN), inhibitor of apoptosis proteins (IAPs), and mouse double minute 2 homolog (MDM2). Specifically, VHL was reported in WO2013 / 106643, and CRBN was reported in WO2015 / 160845.

[0013] A bifunctional compound is a compound in which a ligand of a target protein and a ligand of an E3 ligase are linked via a linker, and some bifunctional compounds have been reported for degrading KRAS proteins (Cell. Chem. Biol., 2020, 27, pp. 19-31; ACS Cent. Sci., 2020, 6, pp. 1367-1375; US2018 / 0015087; WO2019 / 195609; WO2020 / 018788). Summary of the Invention

[0014] It has now surprisingly been found that the combination of compounds of formula (I) as defined herein with certain further anti-cancer agents as defined herein represents a promising strategy for the treatment of cancer.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferences and alternatives for any given aspect, embodiment, feature or parameter of the invention should be considered as disclosed in combination with all preferences and alternatives for all other aspects, features and parameters of the invention, unless the context indicates otherwise.

[0026] Whenever the word "about" is used herein (e.g., in connection with the dose of an active ingredient), it is understood that such variable is approximate and therefore can vary by ±10%, for example ±5%, preferably ±2% (e.g., ±1%) from the number specified herein.

[0027] Those skilled in the art will understand that reference to "treatment" (also "treating") of a particular condition takes its ordinary meaning in the medical arts. Specifically, the term can refer to achieving a decrease in the severity of one or more clinical symptoms associated with the condition or improving the longevity of the treated patient.

[0028] As used herein, reference to a patient refers to a living subject being treated, including a mammalian (e.g., human) patient. Thus, in specific embodiments of related aspects of the invention (e.g., the first, second, fourth, fifth, sixth, and eighth aspects of the invention), the treatment is in a mammal (e.g., a human).

[0029] As used herein, the term "therapeutically effective amount" refers to an amount of a compound that confers a therapeutic effect on a treated patient. The effect may be objective (i.e., measurable by some test or marker) or subjective (i.e., the subject gives an indication of and / or feels an effect). For example, in the context of cancer that forms as one or more solid tumors, the therapeutic effect may be observed as a reduction in the volume of one or more of the tumors.

[0030] For the avoidance of doubt, the compounds of formula (I) and anti-cancer agents described herein may exist as solids, and therefore the scope of the present invention includes all their amorphous, crystalline and partially crystalline forms, but the compounds of formula (I) and anti-cancer agents described herein may also exist as oils.When such compounds exist in crystalline and partially crystalline forms, these forms may include hydrates and solvates, which are included in the scope of the present invention.The compounds of the present invention may also exist in dissolved state.

[0045] The compound of formula (I) and the anticancer agent may have tautomers or geometric isomers depending on the type of substituents. In this specification, the compound of formula (I) and the anticancer agent may be described as only one of the isomers, but the present invention includes tautomers or geometric isomers other than those described, and also includes separated isomers or mixtures thereof.

[0046] The compounds of formula (I) may have one or more asymmetric carbon atoms and may therefore exist in particular enantiomeric and diastereomeric forms thereof. The present invention includes separated enantiomers and diastereomers of the compounds of formula (I) or mixtures thereof.

[0047] Enantiomers of chiral compounds having one or more asymmetric carbon atoms may be given the designation "(R)" and "(S)" for each point of chirality based on methods known in the art (e.g., using the Cahn-Ingold-Prelog ranking rules).

[0048] In certain embodiments, reference to a particular stereoisomer of a compound of Formula (I) may refer to the presence of that particular stereoisomer (e.g., the particular enantiomer or diastereoisomer indicated) in the substantial absence of other stereoisomers (i.e., the stereoisomers have different configurations at one or more of the relevant points of chirality).

[0049] In such cases, the compounds of formula (I) in the relevant configuration may optionally be present in an enantiomeric excess (ee) or diastereomeric excess (de) of at least 60% (e.g., at least 70%, 80%, 90%, 95% or 98%, or especially at least 99%, e.g., at least 99.9%).

[0050] Compounds of formula (I) may have axial chirality, which may refer to compounds having one or more axes about which a set of substituents are held in a spatial arrangement that is not superimposable on its mirror image. For the avoidance of doubt, all axial configurations of such compounds are within the scope of the present invention.

[0051] Enantiomers of axially chiral compounds may be given the designation "M" and "P" based on methods known in the art (e.g., using the Cahn-Ingold-Prelog ranking rules, but with the additional rule that two "close" substituents have a higher ranking than two "distant" substituents).

[0052] In certain embodiments, reference to a particular axial stereoisomer of a compound of Formula (I) can mean the presence of that particular stereoisomer (e.g., an isomer having M-axial asymmetry) in the substantial absence of the corresponding opposite stereoisomer (e.g., an isomer having P-axial asymmetry).

[0138] For the avoidance of doubt, use of the eighth aspect of the invention may have any of the specific features and embodiments described above for the other (e.g. first to seventh) aspects of the invention, including all combinations thereof.

[0139] Preparation of Compounds / Compositions The pharmaceutical compositions, combination products and kits described herein may be prepared in accordance with standard and / or accepted pharmaceutical practice.

[0140] Thus, in a further aspect of the present invention, there is provided a process for the preparation of a pharmaceutical composition as described herein, which process comprises mixing a compound of formula (I) or a pharmaceutically acceptable salt thereof and an anti-cancer agent, both as described herein, with one or more pharmaceutically acceptable excipients.

[0141] In a further aspect of the present invention, there is provided a process for the preparation of a combination product or kit-of-parts as hereinbefore defined, which process comprises mixing a compound of formula (I) or a pharmaceutically acceptable salt thereof and an anti-cancer agent, both as described herein.

[0142] As used herein, reference to mixing means that the two components are suitable for administration together. Thus, in relation to the method for the preparation of the kit of parts defined above, by "mixing" two components with each other, we mean that the two components of the kit of parts are: (i) may be provided as separate formulations (i.e., independently of each other), which formulations are then combined for use in conjunction with each other in combination therapy; or (ii) may be packaged and presented together as a "combination pack" of separate components for use in conjunction with each other in combination therapy; Include.

[0143] The compounds described herein, including the compounds of formula (I) and pharmaceutically acceptable salts thereof and anti-cancer agents described herein, can be prepared according to techniques well known to those skilled in the art, such as those described in the examples provided below and / or those provided in the published literature relating to each such compound.

[0144] Certain compounds described herein, such as the anti-cancer agents described herein, and pharmaceutical compositions containing same, may be commercially available from sources known to those of skill in the art. The compound of formula (I) and its salts can be produced by applying various known synthetic methods using characteristics based on its basic structure or the type of substituents. Depending on the type of functional group, replacing the functional group with an appropriate protecting group (a group that can be easily converted to the functional group) during the process from the raw material to the intermediate is often an effective production technique. Examples of protecting groups include those listed in P.G.M.Wuts and T.W. Greene, "Greene's Protective Groups in Organic Synthesis," 5th Edition, John Wiley & Sons Inc., 2014, and a group appropriately selected from the above protecting groups is used depending on the reaction conditions. In such a method, a reaction is carried out with a protecting group introduced, and then the protecting group is removed as necessary, thereby obtaining the desired compound.

[0145] In addition, prodrugs of the compound of formula (I) can be prepared by introducing the same special protecting group as the above in the process from the raw material to the intermediate, or by further carrying out a reaction using the obtained compound of formula (I). This reaction can be carried out by applying a method known to those skilled in the art, such as conventional esterification, amidation, or dehydration.

[0146] Isolation and purification are carried out by applying conventional chemical procedures, such as extraction, fractional crystallization or various types of fractional chromatography. Various isomers may be prepared by selecting appropriate starting compounds, or may be separated by utilizing the differences in physicochemical properties between isomers. For example, optical isomers can be obtained by conventional optical resolution methods for racemates (e.g., fractional crystallization of racemates with optically active bases or acids to give diastereomeric salts, chromatography using chiral columns, etc.), and can be similarly prepared from optically active appropriate starting compounds.

[0147] In addition, the compound of formula (I) or an intermediate thereof often has axial chirality and is obtained as a mixture of axial stereoisomers, but each axial stereoisomer can be isolated by a conventional separation procedure, for example, separation using octadecylsilyl (ODS) column chromatography or silica gel column chromatography.

[0148] Effect of the invention The treatments described herein may have the advantage that they may be more effective, less toxic, longer acting, more potent, cause fewer side effects, and / or have a better therapeutic profile than treatments for the same conditions known in the prior art.

[0149] Without wishing to be bound by theory, it is believed that the compound of formula (I) has a degradation-inducing effect on G12D mutant KRAS protein and G12D mutant KRAS inhibitory activity, and that the compound of formula (I) can act synergistically in the treatment of cancer, particularly G12D mutant KRAS-positive cancer, when used together with an anticancer drug selected from the group consisting of a CDK4 / 6 inhibitor, an SHP2 inhibitor, an EGFR inhibitor, an mTOR inhibitor, an immune checkpoint inhibitor, a PI3K inhibitor, an SOS1 inhibitor, an AURK inhibitor, and prodrugs thereof.

Please note that the present invention is not limited to the compounds described in the following examples. In addition, the preparation methods of the starting compounds are shown in the preparation examples. The preparation method of the compound of formula (I) is not limited to the preparation methods of the specific examples below, and the compound of formula (I) can also be prepared by a combination of these preparation methods or methods that are obvious to those skilled in the art.

[0244] Example E: In vivo combination therapy with cetuximab in mice xenografted with human KRAS G12D mutation-positive GP5d colon cancer cell line GP5d cells (ECACC, Cat# 95090715) were cultured in DMEM medium supplemented with 10% fetal bovine serum and 1% penicillin-streptomycin solution in an atmosphere of 5% CO2 in air at 37°C. Five-week-old male nude mice (BALB / c nude mice, Charles River Laboratories Japan, Inc.) were inoculated with GP5d cells (2.6 × 10 cells) contained in 0.1 mL of DPBS (containing 50% Cultrex Basement Membrane Extract (R&D Systems)) for tumor development. 6 The animals were randomized and the mean tumor size was approximately 50-100 mm. 3 Treatment began 10 days after tumor inoculation, when the tumor volume reached 100 μg. Animals were assigned to groups using Excel-based randomization software, which performed stratified randomization based on their tumor volume. Each group consisted of eight mice. Test articles were administered as shown in Table 7. Solvent A was prepared by mixing 4% (v / v) ethanol in 5% glucose solution, 1% (v / v) 50% (2-hydroxypropyl)-β-cyclodextrin, and 9% (v / v) HCO-40. The compound of Example 1 was dissolved therein. Cetuximab (anti-EGFR antibody, ERBITUX Injection (Merck Biopharma Co., Ltd.)) was administered undiluted. Tumor size and body weight were measured twice weekly. Tumor volume was calculated using the following formula:

[0245] [Tumor volume (mm 3 )] = [Tumor long diameter (mm)] × [Tumor short diameter (mm)] 2 ×0.5 The TGI rate was calculated using the following formula: TGI (%) = 100 × (1 − [mean tumor volume on day 21 − mean tumor volume on day 0] for each group / [mean tumor volume on day 21 − mean tumor volume on day 0] for the vehicle control group).

[0246] [Table 7]

[0247] As shown in the test results in Table 7, the compound of Example 1, in combination with cetuximab, exhibited antitumor activity in mice bearing human colon cancer cells with a KRAS G12D mutation, suggesting that the combination with the compound of Example 1 is superior to cetuximab monotherapy for the treatment of G12D-mutated KRAS-positive colon cancer. [Industrial Applicability]
