Abstract
Description
[Technical field]
[0001] This application is filed with a sequence listing in electronic format. The sequence listing is provided in a file named A-2262-WO-PCT_SeqList_061019_ST25.txt, created on June 10, 2019, which is 16kb in size. The information in the electronic sequence listing is incorporated herein by reference in its entirety.
[0002] The present invention relates to compounds that inhibit the KRAS G12C protein, methods of using the compounds to treat diseases or conditions, such as cancer, and pharmaceutical compositions containing the compounds. [Background technology]
[0003] KRAS gene mutations are common in pancreatic cancer, lung adenocarcinoma, colon cancer, gallbladder cancer, thyroid cancer, and bile duct cancer. KRAS mutations are also observed in about 25% of patients with NSCLC, and some studies have shown that KRAS mutations are a negative prognostic factor for patients with NSCLC. Recently, V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations have been found to confer resistance to epidermal growth factor receptor (EGFR)-targeted therapy in colon cancer, and thus, the mutation status of KRAS can provide important information before prescribing TKI therapy. Taken together, there is a need for new medical treatments for patients with pancreatic cancer, lung adenocarcinoma, or colon cancer, including those diagnosed with such cancers characterized by KRAS mutations and those who have progressed after chemotherapy.

[0022] As used herein, the terms "amino" or "amine" refer interchangeably to the -NR2 group, where each R is, for example, H or a substituent. In some embodiments, the amino group is further substituted to provide an ammonium ion, for example, NR3 +The ammonium moiety is specifically included in the definition of "amino" or "amine". The substituents can be, for example, alkyl, alkoxy, cycloalkyl, heterocycloalkyl, amido, or carboxylate. The R group can be further substituted with one or more, e.g., 1 to 4, groups selected from, for example, halo, cyano, alkenyl, alkynyl, alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, urea, carbonyl, carboxylate, amine, and amido. An "amide" or "amido" group refers interchangeably to a group similar to an amine or amino group, but further including a C(O), e.g., -C(O)NR2. Some possible amino or amide groups (some with an optional alkylene group, e.g., alkylene-amino or alkylene-amide) are CH2NH2, CH(CH3)NH2, CH(CH3)2NH2, CH2CH2NH2, CH2CH2N(CH3)2, CH2NHCH3, C(O)NHCH3, C(O)N(CH3)2, CH2C(O)NHphenyl, CH2NHC(O)CH3, CH2NH CH2CH2OH, CH2NHCH2CO2H, CH2NH(CH3)CH2CO2CH3, CH2NHCH2CH2OCH3, CH2NH(CH3)CH2CH2OCH3, CH2NH(CH3)CH2C (O)N(CH3)2, CH2NH(CH3)CH2C(O)NHCH3, CH2CH2CCH, CH2NMe2, CH2NH(CH3)CH2CH2OH, CH2NH(CH3)CH2CH2F, CH2N + (CH3)3, CH2NHCH2CHF2, CH2NHCH2CH3, [ka] Includes.
[0023] Collectively, antibodies form a family of plasma proteins known as immunoglobulins and contain immunoglobulin domains. (Janeway et al., Immunobiology: The Immune System in Health and Disease, 4 thed., Elsevier Science Ltd. / Garland Publishing, 1999). As used herein, the term "antibody" refers to a protein having a conventional immunoglobulin type, including heavy and light chains, and including a variable region and a constant region. For example, an antibody may be an IgG, which has a "Y-shaped" structure with two pairs of identical polypeptide chains, each pair having one "light" chain (usually having a molecular weight of about 25 kDa) and one "heavy" chain (usually having a molecular weight of about 50-70 kDa). An antibody has a variable region and a constant region. In the IgG type, the variable region is generally about 100-110 or more amino acids, includes three complementarity determining regions (CDRs), and is primarily responsible for antigen recognition and is substantially different from other antibodies that bind to different antigens. The constant region enables the antibody to recruit cells and molecules of the immune system. The variable region is made up of the N-terminal region of each light and heavy chain, and the constant region is made up of the C-terminal portion of each heavy and light chain. (Janeway et al., “Structure of the Antibody Molecule and the Immunoglobulin Genes”, Immunobiology: The Immune System in Health and Disease, 4 th ed.Elsevier Science Ltd. / Garland Publishing, (1999)).
[0024] The general structure and properties of antibody CDRs have been described in the art. Briefly, in the antibody framework, CDRs are embedded within the framework in the variable regions of heavy and light chains, where they constitute the regions that play a major role in antigen binding and recognition. A variable region usually comprises at least three heavy or light chain CDRs (Kabat et al., 1991, Sequences of Proteins of Immunological Interest, Public Health Service NIH, Bethesda, Md.; see also Chothia and Lesk, 1987, J. Mol. Biol. 196:901-917; Chothia et al., 1989, Nature 342:877-883), which are located within framework regions (referred to as framework regions 1-4, FR1, FR2, FR3 and FR4 by Kabat et al., 1991; see also Chothia and Lesk, 1987, supra).
[0025] The antibody may comprise any constant region known in the art. Human light chains are classified as kappa and lambda light chains. Heavy chains are classified as mu, delta, gamma, alpha, or epsilon, defining the antibody's isotype as IgM, IgD, IgG, IgA, and IgE, respectively. IgG has several subclasses, including, but not limited to, IgG1, IgG2, IgG3, and IgG4. IgM has subclasses, including, but not limited to, IgM1 and IgM2. The embodiments of the present disclosure include all such classes or isotypes of antibodies. The light chain constant region may be, for example, a kappa- or lambda-type light chain constant region, such as a human kappa- or lambda-type light chain constant region. The heavy chain constant region may be, for example, an alpha-, delta-, epsilon-, gamma-, or mu-type heavy chain constant region, such as a human alpha-, delta-, epsilon-, gamma-, or mu-type heavy chain constant region. Thus, in exemplary embodiments, the antibody is of the isotype IgA, IgD, IgE, IgG or IgM, including any one of IgG1, IgG2, IgG3 or IgG4.
[0026] The antibody may be a monoclonal or polyclonal antibody. In some embodiments, the antibody comprises sequences substantially similar to natural antibodies produced by mammals, such as mice, rabbits, goats, horses, chickens, hamsters, and humans. In this regard, the antibody may be considered a mammalian antibody, such as a mouse antibody, a rabbit antibody, a goat antibody, a horse antibody, a chicken antibody, a hamster antibody, and a human antibody. In certain aspects, the antibody is a human antibody. In certain aspects, the antibody is a chimeric or humanized antibody. The term "chimeric antibody" refers to an antibody that contains domains from two or more different antibodies. A chimeric antibody can, for example, contain a constant domain from one species and a variable domain from a second species, or more commonly, can contain stretches of amino acid sequences from at least two species. A chimeric antibody can also contain domains from two or more different antibodies within the same species. The term "humanized", when used in reference to an antibody, refers to an antibody with at least the CDR regions from a non-human source that have been engineered to have a structure and immune function more similar to a true human antibody than the original source antibody. For example, humanization can include the transplantation of CDRs from a non-human antibody, such as a murine antibody, into a human antibody. Humanization can also include selected amino acid substitutions to make the non-human sequence more similar to a human sequence.
[0027] Antibodies can be cleaved into fragments by enzymes such as, for example, papain and pepsin. Papain cleaves antibodies to produce two Fab fragments and a single Fc fragment. Pepsin cleaves antibodies to produce F(ab')2 and pFc' fragments. As used herein, the term "antigen-binding antibody fragment" refers to a portion of an antibody molecule capable of binding to the antigen of the antibody, also known as an "antigen-binding fragment" or "antigen-binding portion." In an illustrative example, the antigen-binding antibody fragment is a Fab fragment or a F(ab')2 fragment.
[0028] The structure of antibodies has been exploited to create a wide range of alternative formats, spanning a molecular weight range of at least about 12-150 kDa, from monomers (n=1) to dimers (n=2), trimers (n=3), tetramers (n=4) and potentially even higher valency (n) ranges, referred to herein as "antibody protein products." Antibody protein products include those based on the complete antibody structure and those that mimic antibody fragments that retain complete antigen-binding capacity, such as scFv, Fab and VHH / VH (discussed below). The smallest antigen-binding antibody fragment that retains an intact antigen-binding site is the Fv fragment, consisting exclusively of the variable (V) region. Either the V region is linked to the scFv (single chain fragment variable) fragment using a soluble, flexible amino acid peptide linker to stabilize the molecule, or a constant (C) domain is added to the V region to generate a Fab fragment [fragment, antigen-binding]. Both scFv and Fab fragments can be easily produced in host cells, e.g., prokaryotic host cells. Other antibody protein products include dimeric and multimeric antibody formats such as diabodies, triabodies and tetrabodies or minibodies (miniAbs), including disulfide bond stabilized scFv (ds-scFv), single chain Fab (scFab) and different formats consisting of scFv linked to oligomerization domains. The smallest fragments are the VHH / VH of camelid heavy chain Abs and single domain Abs (sdAbs). The building blocks most frequently used to generate novel antibody formats are single chain variable (V)-domain antibody fragments (scFv), which contain the V domains from heavy and light chains (VH and VL domains) linked by a peptide linker of about 15 amino acid residues. Peptibodies or peptide-Fc fusions are yet another antibody protein product. The structure of a peptibody consists of a biologically active peptide grafted onto an Fc domain. Peptibodies have been described in detail in the art, see, e.g., Shimamoto et al., mAbs 4(5):586-591 (2012).
[0029] Other antibody protein products include single chain antibodies (SCAs), diabodies, triabodies, tetrabodies, and bispecific or triabodies. Bispecific antibodies can be divided into five major classes: BsIgG, adduct IgG, BsAb fragments, bispecific fusion proteins, and BsAb conjugates. See, e.g., Spiess et al., Molecular Immunology 67(2)Part A:97-106(2015).
[0030] As used herein, the term "aryl" refers to 6~14 Monocyclic or polycyclic aromatic groups, preferably C 6~10 Monocyclic or bicyclic aromatic group or C 10~14 It refers to a polycyclic aromatic group. Examples of aryl groups include, but are not limited to, phenyl, naphthyl, fluorenyl, azulenyl, anthryl, phenanthryl, pyrenyl, biphenyl, and terphenyl. Aryl refers to a C cyclic aromatic ring in which one ring is aromatic and the other ring is saturated, partially unsaturated, or aromatic. 10~14 It also refers to bicyclic and tricyclic carbocycles, such as dihydronaphthyl, indenyl, indanyl or tetrahydronaphthyl (tetralinyl). Unless otherwise indicated, aryl groups are unsubstituted or substituted with, for example, halo, C 1~6 Alkyl, C 2~6 Alkenyl, C 2~6 Alkynyl, -CF3, -OCF3, -NO2, -CN, -NC, -OH, alkoxy, amino, -CO2H, -CO2C1-C6 alkyl, -OCOC1-C6 alkyl, C3-C 10 Cycloalkyl, C3-C 10 Heterocycloalkyl, C5-C 10 Aryl and C5-C 10 It may be substituted with one or more, particularly 1 to 4, groups independently selected from heteroaryl.
[0031] As used herein, the term "cycloalkyl" refers to a monocyclic or polycyclic non-aromatic carbocyclic ring, which may be fused, bridged, or spiro.

[0102] Pharmaceutical compositions containing the compounds disclosed herein can be manufactured in a conventional manner, for example by conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes. Proper formulation depends on the route of administration chosen.
[0103] For oral administration, suitable compositions can be easily formulated by combining the compounds disclosed herein with pharma- ceutically acceptable excipients, such as carriers well known in the art. Such excipients and carriers allow the compounds to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries and suspensions, etc., for oral ingestion by the patient to be treated. Pharmaceutical preparations for oral use can be obtained by adding the compounds disclosed herein with solid excipients, optionally grinding the resulting mixture, and processing the granulated mixture, after adding suitable auxiliaries as necessary, to obtain tablets or dragee cores. Suitable excipients include, for example, fillers and cellulose preparations. Disintegrants can be added as necessary. Pharmaceutically acceptable ingredients are well known for various types of formulations, and can be, for example, binders (e.g., natural or synthetic polymers), lubricants, surfactants, sweeteners and flavorings, coating materials, preservatives, dyes, thickeners, adjuvants, antibacterial agents, antioxidants, and carriers for various formulation types.
[0104] When a therapeutically effective amount of a compound disclosed herein is administered orally, the composition will typically be in the form of a solid formulation (e.g., a tablet, capsule, pill, powder or lozenge) or a liquid formulation (e.g., an aqueous suspension, solution, elixir or syrup).
[0105] When administered in tablet form, the composition may further contain a functional solid and / or solid carrier such as gelatin or an adjuvant. Tablets, capsules and powders may contain about 1 to about 95% of the compound, preferably about 15 to about 90% of the compound.
[0106] When administered in liquid or suspension form, functional liquids and / or liquid carriers such as water, petroleum, or oils of animal or plant origin can be added. The liquid form of the composition can further contain physiological saline, sugar alcohol solution, dextrose or other sugar solution, or glycol. When administered in liquid or suspension form, the composition can contain about 0.5 to about 90% by weight of the compound disclosed herein, preferably about 1 to about 50% of the compound disclosed herein. In one contemplated embodiment, the liquid carrier is non-aqueous or substantially non-aqueous. For administration in liquid form, the composition can be provided as a rapidly dissolving solid formulation for dissolution or suspension immediately prior to administration.
[0107] When a therapeutically effective amount of the compounds disclosed herein is administered by intravenous, cutaneous or subcutaneous injection, the composition is in the form of a pyrogen-free, parenterally acceptable aqueous solution. The preparation of such parenterally acceptable solutions, with due consideration of pH, isotonicity, stability, and the like, is within the skill of the art. A preferred composition for intravenous, cutaneous or subcutaneous injection typically contains an isotonic vehicle in addition to the compounds disclosed herein. Such compositions can be prepared for administration as an aqueous solution of a free base or a pharmacologically acceptable salt suitably mixed with a surfactant, such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof, and in oils. Under ordinary conditions of storage and use, these preparations can optionally contain a preservative to prevent the growth of microorganisms.
[0108] Injectable compositions may include sterile aqueous solutions, suspensions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions, suspensions or dispersions. In all embodiments, the form must be sterile and fluid to the extent that easy syringability exists. The form must be stable under the conditions of manufacture and storage and must be resistant to the contaminating action of microorganisms such as bacteria and fungi, optionally including preservatives. The carrier may be, for example, a solvent or dispersion medium containing water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, etc.), suitable mixtures thereof, and vegetable oils. In one possible embodiment, the carrier is non-aqueous or substantially non-aqueous. The proper fluidity can be maintained, for example, by the use of a coating agent such as lecithin, by maintaining the particle size of the compound required in the embodiment of the dispersion, and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and thimerosal. In many embodiments, it is preferable to include an isotonic agent, for example, sugar or sodium chloride. Prolonged absorption of the injectable compositions can be achieved by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.
[0109] Sterile injection is prepared by incorporating the active compound in the required amount in a suitable solvent together with various other ingredients as listed above, as necessary, followed by sterilization by filtration.Generally, dispersion is prepared by incorporating various sterilized active ingredients into a sterile vehicle that contains a basic dispersion medium and other desired ingredients from the ingredients listed above.In the embodiment of sterile powder for preparing sterile injection, the preferred preparation method is vacuum drying and freeze-drying technology, which obtains powder of active ingredient plus any additional desired ingredients from the solution that has been previously sterilized and filtered.
[0110] Slow or sustained release formulations can also be prepared to achieve controlled release of active compounds in contact with fluids in the digestive tract and provide a substantially constant and effective level of active compounds in plasma. For example, release can be controlled by one or more of dissolution, diffusion and ion exchange. In addition, slow release techniques can enhance absorption through saturable or restricted pathways in the digestive tract. For example, the compounds can be embedded in a polymer matrix of biodegradable polymers, water-soluble polymers or a mixture of both, and optionally a suitable surfactant, for this purpose. In this case, embedding can mean incorporating microparticles in a polymer matrix. Controlled release formulations can also be obtained by encapsulation of dispersed microparticles or emulsified microdroplets via known dispersion or emulsion coating techniques.

In some embodiments, samples are evaluated for G12C KRAS, HRAS or NRAS mutations by real-time PCR. In real-time PCR, a fluorescent probe specific for KRAS, HRAS or NRAS G12C mutations is used. If a mutation is present, the probe binds and fluorescence is detected. In some embodiments, KRAS, HRAS, or NRAS G12C mutations are identified using direct sequencing of specific regions in the KRAS, HRAS, or NRAS genes (e.g., exon 2 and / or exon 3). This technique identifies all possible mutations in the sequenced region.
[0129] Methods for detecting mutations in KRAS, HRAS or NRAS proteins are known to those of skill in the art, including, but not limited to, detection of mutant KRAS, HRAS or NRAS proteins using binding agents (e.g., antibodies) specific for the mutant proteins, protein electrophoresis and Western blotting, and direct peptide sequencing.

The kit comprises a container, such as a divided bottle or a divided foil packet, for containing the separate compositions. Further examples of containers include syringes, boxes and bags. In some embodiments, the kit comprises instructions for using the separate components. The kit form is particularly advantageous when the separate components are preferably administered in different dosage forms (e.g., oral and parenteral), when administered at different dosing intervals, or when dosage adjustment of the individual components of the combination is desired by the prescribing medical professional.
