Description
[0001] Tricyclic compounds for the treatment of cancer
[0002] The present invention relates to organic compounds useful for therapy and / or prophylaxis in a mammal, and in particular to inhibition of KRAS G12V mutant useful for treating cancers.
[0003] FIELD OF THE INVENTION RAS is one of the most well-known proto-oncogenes. Approximately 30% of human cancers contain mutations in three most notable members, KRAS, HRAS, and NRAS, making them the most prevalent oncogenic drivers. KRAS mutations are generally associated with poor prognosis, especially in colorectal cancer, pancreatic cancer, lung cancers. As the most frequently mutated RAS isoform, KRAS has been intensively studied in the past years leading to the discovery of commonly occurring KRAS alleles, including G12D, G12V, G12C, G13D, G12R, G12A, G12S, Q61H, etc.
[0004] KRAS G12V, in particular, represents a significant unmet medical need with a high prevalence across multiple cancer types. Globally, there are approximately 160,000 colorectal cancer (CRC) patients (10.3%), 130,000 pancreatic ductal adenocarcinoma (PDAC) patients (28.3%), and 120,000 non-small cell lung cancer (NSCLC) patients (5.4%) harboring the G12V mutation (AACR GENIE vl5.0 and WHO Cancer Today). Despite the high prevalence, effective treatments for RAS-driven metastatic CRC (mCRC) and PDAC are lacking, underscoring the urgent need for novel therapeutic strategies. RAS-targeting therapies have the potential to revolutionize first-line treatment for RAS-mutated tumors, offering new hope for patients with these challenging cancers. The KRAS G12V mutation is a clinically validated foundational target, with strong human genetic evidence linking it to cancer. Significant correlations between genetic and pharmacological perturbations and disease risk further emphasize its importance. Clinical support for targeting KRAS G12V is bolstered by positive Phase 1 data in PDAC from panRAS inhibitor trials and the approval of G12C-targeting drugs, which indicate a clinically meaningful impact. The necessity for selectivity for improved combinability is highlighted by the inadequate response in CRC, which necessitates combination therapy due to mutant KRAS requiring APC loss and strong EGFR-mediated feedback. PanRAS inhibitors share common overlapping toxicities with Cetuximab (GI toxicity, rash) and Bevacizumab (GI toxicity), suggesting that enhanced selectivity may improve combinability and therapeutic outcomes.
[0005] The intrinsic G12V target biology underscores the promising therapeutic benefits of selective inhibitors. The high GTP binding affinity and slower hydrolysis rates of G12V (compared to G12C and G12D) prolong RAS activation, necessitating the targeting of the active G12V state. Additionally, the high transforming and migration potentials, along with a worse prognosis in PDAC, underscore G12V addiction and the significant clinical impact of its inhibition.
[0006] The promising efficacy of combined immune checkpoint inhibitors (ICIs) in non-small cell lung cancer (NSCLC) and the improved progression-free survival (PFS) and overall survival (OS) observed with the use of metastatic surgery and Bevacizumab in metastatic colorectal cancer (mCRC) suggest significant advantages of these combination therapies. These findings underscore the potential of selective KRAS G12V inhibitors to address critical unmet needs and enhance patient outcomes in RAS-driven cancers.
[0007] As such, compounds of this invention were invented to target and inhibit KRAS G12V selectively for the treatment of KRAS G12V mutant driven cancers.

[0500] PHARMACEUTICAL COMPOSITIONS AND ADMINISTRATION
[0501] Another embodiment provides pharmaceutical compositions or medicaments containing the compounds of the invention and a therapeutically inert carrier, diluent or excipient, as well as methods of using the compounds of the invention to prepare such compositions and medicaments. In one example, compounds of formula (I) may be formulated by mixing at ambient temperature at the appropriate pH, and at the desired degree of purity, with physiologically acceptable carriers, i.e., carriers that are non-toxic to recipients at the dosages and concentrations employed into a galenical administration form. The pH of the formulation depends mainly on the particular use and the concentration of compound but preferably ranges anywhere from about 3 to about 8. In one example, a compound of formula (I) is formulated in an acetate buffer, at pH 5. In another embodiment, the compounds of formula (I) are sterile. The compound may be stored, for example, as a solid or amorphous composition, as a lyophilized formulation or as an aqueous solution.
[0502] Compositions are formulated, dosed, and administered in a fashion consistent with good medical practice. Factors for consideration in this context include the particular disorder being treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the site of delivery of the agent, the method of administration, the scheduling of administration, and other factors known to medical practitioners. The “effective amount” of the compound to be administered will be governed by such considerations and is the minimum amount necessary to inhibit mutant RAS (e.g. KRAS G12C) interaction with RAF, blocking the oncogenic MAPK signaling. For example, such amount may be below the amount that is toxic to normal cells, or the mammal as a whole.
[0503] In one example, the pharmaceutically effective amount of the compound of the invention administered parenterally per dose will be in the range of about 0.1 to 1000 mg / kg, alternatively about 0.1 to 1000 mg / kg of patient body weight per day, with the typical initial range of compound used being 0.3 to 15 mg / kg / day. In another embodiment, oral unit dosage forms, such as tablets and capsules, preferably contain from about 1 to about 1000 mg of the compound of the invention.
[0504] The compounds of the invention may be administered by any suitable means, including oral, topical (including buccal and sublingual), rectal, vaginal, transdermal, parenteral, subcutaneous, intraperitoneal, intrapulmonary, intradermal, intrathecal and epidural and intranasal, and, if desired for local treatment, intralesional administration. Parenteral infusions include intramuscular, intravenous, intraarterial, intraperitoneal, or subcutaneous administration.
[0505] The compounds of the present invention may be administered in any convenient administrative form, e.g., tablets, powders, capsules, solutions, dispersions, suspensions, syrups, sprays, suppositories, gels, emulsions, patches, etc. Such compositions may contain components conventional in pharmaceutical preparations, e.g., diluents, carriers, pH modifiers, sweeteners, bulking agents, and further active agents. A typical formulation is prepared by mixing a compound of the present invention and a carrier or excipient. Suitable carriers and excipients are well known to those skilled in the art and are described in detail in, e.g., Ansel, Howard C., et al., Ansel’s Pharmaceutical Dosage Forms and Delivery Systems. Philadelphia: Lippincott, Williams & Wilkins, 2004; Gennaro, Alfonso R., et al. Remington: The Science and Practice of Pharmacy. Philadelphia: Lippincott, Williams & Wilkins, 2000; and Rowe, Raymond C. Handbook of Pharmaceutical Excipients. Chicago, Pharmaceutical Press, 2005. The formulations may also include one or more buffers, stabilizing agents, surfactants, wetting agents, lubricating agents, emulsifiers, suspending agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants, sweeteners, perfuming agents, flavoring agents, diluents and other known additives to provide an elegant presentation of the drug (i.e., a compound of the present invention or pharmaceutical composition thereof) or aid in the manufacturing of the pharmaceutical product (i.e., medicament).
