Study to Evaluate the Efficacy and Safety of TT-00420 (Tinengotinib) in Cholangiocarcinoma

This is a Phase II, open-label study to evaluate the efficacy and safety of TT00420 in patients with advanced/metastatic and surgically unresectable cholangiocarcinoma (CCA) with 1) FGFR 2 fusions who failed prior FGFR inhibitor treatment, 2) FGFR2 fusions who responded on prior FGFR inhibitor treatment, 3) with other FGFR alterations, or 4) whose tumors do not contain a detectable FGFR alteration.
