Pemigatinib, a potent inhibitor of FGFRs for the treatment of cholangiocarcinoma.

The prognosis of patients affected by cholangiocarcinoma is classically poor. Until recently, chemotherapeutic drugs were the only systemic treatment option available, leading to an overall survival lower than 1 year. In recent decades, different genetic alterations have been identified as playing a key role in the oncogenic signaling. A subgroup of intrahepatic cholangiocarcinoma is characterized by FGFR family mutations, more frequently represented by gene fusions of FGFR2. Based on the results of FIGHT-202 trial, in April 2020 the US FDA approved the FGFR inhibitor pemigatinib in advanced previously treated cholangiocarcinoma patients with FGFR2 rearrangements, opening the way to targeted therapy in this disease. This review summarizes the body of evidence about the efficacy of pemigatinib in cholangiocarcinoma.
