Study of Futibatinib in Patients With Advanced Cholangiocarcinoma With FGFR2 Fusion or Rearrangement

This is an open-label, multinational, randomized Phase 2 study confirming the clinical benefit of 20 mg futibatinib and evaluating the safety and efficacy of 16 mg futibatinib in previously treated CCA harboring FGFR2 gene fusions and other rearrangements. Eligible patients will be randomized on a 1:1 basis to the following study arms: * Patients will receive futibatinib at an oral dose of 16 mg, administered daily (QD) on every day of a 21-day cycle. * Patients will receive futibatinib at an oral dose of 20 mg, administered daily (QD) on every day of a 21-day cycle. Patients may continue to receive continuous futibatinib until documentation of progressive disease (PD) per RECIST 1.1, or until other withdrawal criteria are met, whichever comes first.
