The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for Kinnate Biopharma’s investigational pan-FGFR inhibitor, KIN-3248, for the treatment of patients with unresectable, locally advanced or metastatic cholangiocarcinoma (CCA) harboring fibroblast growth factor receptor 2 (FGFR2) gene fusions or other alterations, who have received at least one prior systemic therapy.
Cholangiocarcinoma, also known as bile duct cancer, is a rare condition, often diagnosed when it is advanced. Research has shown that FGFR is an actionable alteration in patients with CCA. FGFRs are tyrosine kinases that play a crucial role in cell proliferation, differentiation, migration and survival. FGFR2 gene fusions or other alterations are identified in approximately 16% of intrahepatic cholangiocarcinoma (ICC) tumors.
Fast Track is a process designed by the FDA to facilitate the development and expedite the review of drugs to treat serious conditions and fulfill an unmet medical need. A therapeutic candidate that receives Fast Track designation is eligible for more frequent interactions with the FDA to discuss the candidate’s development plan, and if relevant criteria are met, for Accelerated Approval and Priority Review.
