FDA approves Pemazyre to treat cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion.- Incyte Corpn.

Incyte announced that the FDA has approved Pemazyre (pemigatinib), a kinase inhibitor indicated for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test. Pemazyre is the first and only FDA-approved treatment for this indication, which was approved under accelerated approval based on overall response rate and duration of response (DOR). Continued approval may be contingent on verification and description of clinical benefit in a confirmatory trial(s).

The FDA approval was based on data from the FIGHT-202 study, a multi-center, open-label, single-arm study that evaluated Pemazyre as a treatment for adults with cholangiocarcinoma. In patients harboring FGFR2 fusions or rearrangements (Cohort A), Pemazyre monotherapy resulted in an overall response rate of 36% (primary endpoint), and median DOR of 9.1 months (secondary endpoint). Warnings and precautions for Pemazyre include eye problems such as dry or inflamed eyes, inflamed cornea, increased tears and a disorder of the retina; high levels of phosphate in the blood; and, for women who are pregnant, a risk of harm to the unborn baby or loss of pregnancy.
