We are a clinical-stage biotechnology company focused on developing precision therapies for genetically defined diseases. Our approach is to design rational precision therapies that treat the underlying cause of disease and improve the lives of patients. Our most advanced program is bezuclastinib, also known as CGT9486, a highly selective tyrosine kinase inhibitor that is designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. In the vast majority of cases, KIT D816V is responsible for driving Systemic Mastocytosis (“SM”), a serious and rare disease caused by unchecked proliferation of mast cells. Exon 17 mutations are also found in patients with advanced gastrointestinal stromal tumors (“GIST”), a type of cancer with strong dependence on oncogenic KIT signaling. Bezuclastinib is a highly selective and potent KIT inhibitor with the potential to provide a new treatment option for these patient populations. We are developing bezuclastinib to treat patients living with Non-Advanced Systemic Mastocytosis (“NonAdvSM”), Advanced Systemic Mastocytosis (“AdvSM”) and GIST, and in 2025 we reported positive top-line results from registrational trials in each of these indications. We are building an internal commercial organization and expect to launch bezuclastinib commercially in the United State in the second half of 2026, pending regulatory approval. We also have an ongoing Phase 1 study of our novel internally developed FGFR2/3 inhibitor and have initiated a Phase 1 study of our CNS-penetrant, selective mutant ErbB2 inhibitor.
