A Study of Fluzoparib in Combination With mFOLFIRINOX in Patients With Advanced Pancreatic Cancer

A Phase Ib/II Study to Assess the Tolerability, Safety and Efficacy of Fluzoparib in Combination With mFOLFIRINOX Followed by Fluzoparib Maintenance Monotherapy in Patients With Advanced Pancreatic Cancer

The study is being conducted to: a) evaluate the tolerability and safety of the co-administration of Fluzoparib and mFOLFIRINOX followed by Fluzoparib Maintenance Monotherapy in patients with advanced pancreatic cancer, and establish the maximum tolerated dose and recommended phase II dose of the combination; and b) assess the efficacy of the co-administration of Fluzoparib and mFOLFIRINOX followed by Fluzoparib Maintenance Monotherapy in patients with advanced pancreatic cancer.
