Pemigatinib is a small molecule kinase inhibitor with antitumour activity. It works by inhibiting fibroblast growth factor receptors (FGFRs), which are receptor tyrosine kinases that activate signalling pathways in tumour cells.[A193719] FGFRs gained attention as potential therapeutic targets in selected cancers, as FGFR gene alterations were observed in a wide variety of cancers including those of the urinary bladder, breast, ovary, prostate, endometrium, lung, and stomach.[A198984] Deregulated FGFR signalling pathway can lead the development of oncogenes and tumour-promoting physiological processes, such as cancer cell proliferation, enhanced angiogenesis, and evasion of cell death.[A193716] In April 2020, pemigatinib was approved by the FDA for the treatment of unresectable locally advanced or metastatic cholangiocarcinoma in previously treated adult patients with a fibroblast growth factor receptor 2 (FGFR2) gene fusion or other rearrangements as detected by an FDA-approved test.[L13068] Cholangiocarcinoma is the most common primary malignancy affecting the biliary tract and the second most common primary hepatic malignancy. This malignancy accounts for 15% to 20% of primary hepatobiliary malignancies, which account for 13% of overall cancer-related global mortality. With increasing research on the pathogenesis of cholangiocarcinoma and potential therapeutic targets for anticancer drug treatment, recent studies show that up to 45% of patients with intrahepatic cholangiocarcinoma exhibited gene rearrangements resulting in oncogenic fibroblast growth factor 2 (FGFR2) fusion proteins.[A198963] The FDA-approved indication for pemigatinib was granted under accelerated approval based on the overall response rate and duration of response in pre-marketing clinical trials. Pemigatinib is marketed under the brand name Pemazyre, and it is available as oral tablets.[L13050]

Indication
Pemigatinib is indicated for the treatment of unresectable locally advanced or metastatic cholangiocarcinoma in previously-treated adult patients with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test.[L13050] It is also indicated for the treatment of adults with relapsed or refractory myeloid/lymphoid neoplasms (MLNs) with FGFR1 rearrangement.[L43005]
