FDA Accelerated Approval of Futibatinib for Intrahepatic Cholangiocarcinoma
November 2022: The Food and Drug Administration granted accelerated approval to futibatinib (Lytgobi, Taiho Oncology, Inc.) for adult patients with previously treated, unresectable, locally advanced or metastatic intrahepatic cholangiocarcinoma harboring fibroblast growth factor receptor 2 (FGFR2) gene fusions or other rearrangements.
TAS-120-101 Clinical Trial Efficacy and Results
Efficacy was evaluated in TAS-120-101 (NCT02052778), a multicenter, open-label, single-arm trial that enrolled 103 patients with previously treated, unresectable, locally advanced, or metastatic intrahepatic cholangiocarcinoma harboring a FGFR2 gene fusion or other rearrangement. The presence of FGFR2 fusions or other rearrangements was determined using next generation sequencing testing. Patients received 20 mg of futibatinib orally once daily until disease progression or unacceptable toxicity.
The major efficacy outcome measures were overall response rate (ORR) and duration of response (DoR) as determined by an independent review committee according to RECIST v1.1. ORR was 42% (95% Confidence Interval [CI]: 32, 52); all 43 responders achieved partial responses. The median DoR was 9.7 months (95% CI: 7.6, 17.1).
