Targeted Therapies Transform Biliary Tract Cancer Treatment Landscape with FGFR2 Inhibitors Leading Clinical Advances
- Biliary tract cancer treatment has evolved from traditional cytotoxic chemotherapy to include targeted therapies based on specific molecular alterations, with FGFR2 inhibitors showing particularly promising results.
- Pemigatinib and futibatinib, selective FGFR inhibitors, have demonstrated significant clinical efficacy with response rates of 35% and 42% respectively in patients with FGFR2 fusions.
- Comprehensive next-generation sequencing has become the standard approach for identifying actionable molecular alterations, with IDH1/2 mutations, FGFR2 fusions, and ERBB2 alterations being the most clinically significant biomarkers.
- The rarity of biliary tract cancers presents unique challenges in treatment access, making clinical trials essential for patients with molecular alterations that have FDA-approved therapies in other disease states.
