Futibatinib and Pembrolizumab for the Treatment of Advanced or Metastatic FGF19 Positive BCLC Stage A, B, or C Liver Cancer


About this study

This is a single-arm, two-stage, phase II trial to assess the efficacy of futibatinib plus pembrolizumab in advanced hepatocellular carcinoma for patients with FGF19 expression. Patients will receive futibatinib 20mg daily Days 1-21 and will receive pembrolizumab 200mg Day 1 of each 21 day cycle per current clinical standard of care. Patient will receive treatment until disease progression or unacceptable toxicities. Patients will undergo restaging scans every 3 cycles. Subjects will be monitored for adverse events from the beginning of the study drug to 28 days after the last dose. We will collect blood samples for determination of cell free DNA and circulating tumor cells at baseline, after 3 and 6 cycles, and at progression. We will collect tumor biopsy specimens before treatment initiation to develop patient derived tumor organoid.
