On January 29, 2021 Incyte (Nasdaq:INCY) reported that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion recommending the conditional marketing authorization of pemigatinib for the treatment of adults with unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or rearrangement that is relapsed or refractory, after at least one line of systemic therapy (Press release, Incyte, JAN 29, 2021, View Source [SID1234574416]).

"The positive CHMP opinion is a crucial milestone for patients with cholangiocarcinoma, who often have very limited treatment options due to the difficulty of identifying patients during the early disease stages," said Peter Langmuir, M.D., Group Vice President, Oncology Targeted Therapeutics, Incyte. "Following the recent FDA approval of pemigatinib (Pemazyre), we are delighted to be closer to offering the first targeted therapy in Europe to benefit these patients."
The CHMP opinion is based on data from the FIGHT-202 study evaluating the safety and efficacy of pemigatinib in adult patients with previously treated, locally advanced or metastatic cholangiocarcinoma with documented FGF/FGFR status. The CHMP’s opinion to recommend the use of pemigatinib is now being reviewed by the European Commission, which has the authority to grant marketing authorizations for medicinal products in the European Union (EU). If approved, pemigatinib will be the first targeted treatment in the EU indicated for patients with unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or rearrangement and would be commercialized under the brand name Pemazyre.
Cholangiocarcinoma is a rare cancer that forms in the bile duct. It is classified based on its origin: intrahepatic cholangiocarcinoma (iCCA) occurs in the bile duct inside the liver and extrahepatic cholangiocarcinoma occurs in the bile duct outside the liver. Patients with cholangiocarcinoma are often diagnosed at a late or advanced stage when the prognosis is poor1,2. In Europe, the incidence of cholangiocarcinoma ranges between 6,000 – 8,0003,4. FGFR2 fusions or rearrangements occur almost exclusively in iCCA, where they are observed in 10-16 percent of patients5,6,7.
About FIGHT-202
The FIGHT-202 Phase 2, open-label, multicenter study (NCT02924376) is evaluating the safety and efficacy of pemigatinib – a selective fibroblast growth factor receptor (FGFR) inhibitor – in adult (age ≥ 18 years) patients with previously treated, locally advanced or metastatic cholangiocarcinoma with documented FGF/FGFR status.
Patients were enrolled into one of three cohorts – Cohort A (FGFR2 fusions or rearrangements), Cohort B (other FGF/FGFR genetic alterations) or Cohort C (no FGF/FGFR genetic alterations). All patients received 13.5 mg pemigatinib orally once daily (QD) on a 21-day cycle (two weeks on/one week off) until radiological disease progression or unacceptable toxicity.
The primary endpoint of FIGHT-202 is overall response rate (ORR) in Cohort A, assessed by independent review per RECIST v1.1. Secondary endpoints include ORR; progression free survival (PFS), overall survival (OS), duration of response (DOR), disease control rate (DCR) and safety in all cohorts.

About FIGHT
The FIGHT (FIbroblast Growth factor receptor in oncology and Hematology Trials) clinical trial program includes ongoing Phase 2 and 3 studies investigating safety and efficacy of pemigatinib therapy across several FGFR-driven malignancies. Phase 2 monotherapy studies include FIGHT-202, as well as FIGHT-201 investigating pemigatinib in patients with metastatic or surgically unresectable bladder cancer, including with activating FGFR3 mutations or fusions/rearrangements; FIGHT-203 in patients with myeloproliferative neoplasms with activating FGFR1 fusions/rearrangements; FIGHT-207 in patients with previously treated, locally-advanced/metastatic or surgically unresectable solid tumor malignancies harboring activating FGFR mutations or fusions/rearrangements, irrespective of tumor type.
FIGHT-302 is a Phase 3 study investigating pemigatinib as a first-line treatment for patients with cholangiocarcinoma with FGFR2 fusions or rearrangements.
About FGFR and Pemigatinib
Fibroblast growth factor receptors (FGFRs) play an important role in tumor cell proliferation and survival, migration and angiogenesis (the formation of new blood vessels). Activating fusions, rearrangements, translocations and gene amplifications in FGFRs are closely correlated with the development of various cancers.
Pemigatinib is a potent, selective, oral inhibitor of FGFR isoforms 1, 2 and 3 which, in preclinical studies, has demonstrated selective pharmacologic activity against cancer cells with FGFR alterations.
