Undruggable to druggable
Targeting and developing a small molecule inhibitor for RAS mutated cancers
RAS is one of the most frequently mutated oncogenes in human cancer. Mutation in the RAS (KRAS, NRAS, HRAS) oncogene are present in approximately 30% of all human cancers driving tumor cell growth and metastasis by aberrant activation of RAS mediated signaling. We are targeting KRAS in difficult to treat cancers including lung, colon, pancreatic, and NRAS in melanoma, lung, acute myeloid leukemia and myeloma. KRAS inhibitors have been developed to target the specific KRAS G12C mutation, but these therapies are limited to only around 8-10% of KRAS mutant-driven cancers. We are developing a small molecule inhibitor that targets previously “undruggable” mutant RAS including KRAS (G12D, G12C, G12V) and NRAS (61QR, Q61L, Q61K, Q61H, G12D).
RAS mutations are also prevalent in 10–30% of myeloid malignancies and particularly NRAS (G12D, G13D, Q61X) mutations are frequent in acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN), chronic myelomonocytic leukemia (CMML).
There are currently no approved targeted drugs to mutant NRAS, albeit a few in preclinical development.
