In the phase 2, multicenter, open-label FIGHT-202 trial, previously treated patients with metastatic CCA with FGFR2 fusions or FGFR2 rearrangements (n = 107), other FGFR mutations (n = 20), or wild-type FGFR (n = 18) received 13.5 mg of pemigatinib once daily on day 1–14 of a 21-day cycle [52]. This evidence concerns the gene FGFR2 and cholangiocarcinoma.
