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).
Our research into FGFR2 fusions or rearrangements in cholangiocarcinoma and the development of Pemazyre as the first targeted treatment option demonstrates our commitment to translating scientific discovery into solutions that can positively impact patients’ lives,” said Hervé Hoppenot, Chief Executive Officer, Incyte. “We’re proud to bring Pemazyre to patients and will make this new treatment available immediately.”
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.
The FDA granted Pemazyre Breakthrough Therapy designation for the treatment of patients with previously treated advanced/metastatic or unresectable FGFR2 translocated cholangiocarcinoma. Additionally, the FDA granted Pemazyre Orphan Drug designation for the treatment of cholangiocarcinoma, and the New Drug Application (NDA) for Pemazyre was reviewed under the FDA’s Priority Review program.
“Although cholangiocarcinoma is considered a rare disease, it has been on the rise over the past three decades,”1,2 said Ghassan Abou-Alfa, M.D., Memorial Sloan Kettering Cancer Center. “It is encouraging to have a new targeted treatment option for patients who historically have had limited options after first-line chemotherapy or surgery, in which relapse rates remain high.”
Cholangiocarcinoma is a rare cancer that forms in the bile duct. It is classified based on its anatomical 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 poor.3,4 The incidence of cholangiocarcinoma varies regionally and ranges between 0.3-3.4 per 100,000 in North America and Europe.3 FGFR2 fusions or rearrangements occur almost exclusively in iCCA, where they are observed in 10-16% of patients.5-7 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.
“Today’s approval of Pemazyre provides an exciting new treatment option for patients and will bring hope to those who typically face a difficult diagnosis journey and poor prognosis,” said Stacie Lindsey, President, Cholangiocarcinoma Foundation.
Incyte is committed to supporting patients and removing barriers to access medicines. Eligible patients in the U.S. who are prescribed Pemazyre have access to IncyteCARES (Connecting to Access, Reimbursement, Education and Support), a comprehensive program offering patient support, including financial assistance and ongoing education and resources to eligible patients. More information is available at Pemazyre.com.
The FDA is also expected to approve FoundationOne®CDx as the companion diagnostic for Pemazyre. FoundationOne CDx is Foundation Medicine’s comprehensive genomic profiling assay and broad companion diagnostic platform approved for all solid tumors. If approved, this companion diagnostic would help identify patients with FGFR2 fusions or rearrangements who may be eligible for Pemazyre.
he FIGHT-202 Phase 2 multi-center, open-label, single-arm study (NCT02924376) evaluated the safety and efficacy of Pemazyre – a selective fibroblast growth factor receptor (FGFR) inhibitor – in adult (age ≥18 years) patients with previously treated, locally advanced or metastatic cholangiocarcinoma with documented FGFR2 fusion or rearrangement.
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 Pemazyre 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 was overall response rate (ORR) in Cohort A, assessed by independent review per RECIST v1.1. Secondary endpoints include ORR in Cohorts B, A plus B, and C; and duration of response (DOR).
The FIGHT (FIbroblast Growth factor receptor in oncology and Hematology Trials) clinical trial program includes ongoing Phase 2 and 3 studies investigating the safety and efficacy of Pemazyre therapy across several FGFR-driven malignancies. Phase 2 monotherapy studies include FIGHT-202, as well as FIGHT-201 investigating Pemazyre 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-205 is a Phase 2 study investigating Pemazyre plus pembrolizumab combination therapy and Pemazyre monotherapy in patients with previously untreated, metastatic or unresectable bladder cancer harboring FGFR3 mutations or fusions/rearrangements who are not eligible to receive cisplatin. FIGHT-302 is a Phase 3 study investigating Pemazyre as a first-line treatment for patients with cholangiocarcinoma with FGFR2 fusions or rearrangements.
Pemazyre is 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 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.
Pemazyre is marketed by Incyte in the United States. Incyte has granted Innovent Biologics, Inc. rights to develop and commercialize pemigatinib in hematology and oncology in Mainland China, Hong Kong, Macau and Taiwan. Incyte has retained all other rights to develop and commercialize pemigatinib outside of the United States.
Additionally, Incyte’s marketing authorization application (MAA) seeking the approval of pemigatinib for patients with cholangiocarcinoma in the EU has been validated by the European Medicines Agency (EMA) and is currently under review for the treatment of adults with 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.
