Futibatinib Versus Gemcitabine-Cisplatin Chemotherapy as First-Line Treatment of Patients With Advanced Cholangiocarcinoma Harboring FGFR2 Gene Rearrangements

This is an open-label, multinational, parallel 2-arm, randomized Phase 3 study evaluating the efficacy and safety of futibatinib versus gemcitabine-cisplatin chemotherapy as first-line treatment of participants with advanced, metastatic, or recurrent unresectable intrahepatic cholangiocarcinoma (iCCA) harboring FGFR2 gene rearrangements

Study TAS-120-301 is an open-label, multinational, parallel 2-arm, randomized Phase 3 study evaluating the efficacy and safety of futibatinib versus gemcitabine-cisplatin chemotherapy as first-line treatment of participants with advanced, metastatic, or recurrent unresectable iCCA harboring FGFR2 gene rearrangements. Eligible participants will be randomized on a 1:1 basis to the following study arms: * Experimental Arm: Participants will receive futibatinib at an oral dose of 20 mg, administered daily (QD) on every day of a 21-day cycle. * Control Arm: On Days 1 and 8 of a 21-day cycle, participants will receive: * Cisplatin 25 mg/m2 in 1000 mL 0.9% saline by intravenous (IV) infusion over 1 hour, followed by 500 millilliteres (mL) 0.9 percent (%) saline over 30 minutes; and * Gemcitabine 1000 mg/m2 in 250-500 mL 0.9% saline by IV infusion over 30 minutes, beginning after completion of the cisplatin and saline infusions. Participants in the Experimental Arm may continue to receive continuous futibatinib until documentation of progressive disease (PD) per Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v 1.1), or until other withdrawal criteria are met, whichever comes first. However, treatment may continue following PD per RECIST 1.1 if the participants is clinically stable and is considered by the Investigator to be deriving continued clinical benefit from futibatinib. Participants in the Control Arm may receive gemcitabine-cisplatin chemotherapy for up to 8 cycles or until PD or other withdrawal criteria are met, whichever comes first. Participants who discontinue gemcitabine-cisplatin due to documented disease progression (by ICR) may receive treatment with futibatinib ("crossover"), if medically appropriate in the opinion of the Investigator and if criteria for futibatinib treatment are met.
