Incyte Provides Regulatory Update on Retifanlimab for the Treatment of Certain Patients with Squamous Cell Carcinoma of the Anal Canal (SCAC)

WILMINGTON, Del. – Incyte Corporation (Nasdaq:INCY) today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) regarding its Biologics License Application (BLA) for retifanlimab, an intravenous PD-1 inhibitor, for the treatment of adult patients with locally advanced or metastatic squamous cell carcinoma of the anal canal (SCAC) who have progressed on, or who are intolerant of, platinum-based chemotherapy.

The complete response letter states that the FDA cannot approve the application in its present form. Consistent with the Oncologic Drugs Advisory Committee recommendation on June 24, 2021, the FDA determined that additional data are needed to demonstrate the clinical benefit of retifanlimab for the treatment of patients with advanced or metastatic SCAC. Incyte is reviewing the letter and will discuss next steps with the FDA.

“Patients with SCAC who have progressed after first-line chemotherapy currently do not have approved treatment options,” said Hervé Hoppenot, Chief Executive Officer, Incyte. “While we are not surprised with the FDA decision given the ODAC recommendation, we are disappointed. We remain committed to advancing science to find solutions for patients with unmet medical needs, and we will ensure close coordination with the FDA in order to address feedback and determine next steps for the review of retifanlimab.”

The BLA submission was based on data from the Phase 2 POD1UM-202 trial evaluating retifanlimab in previously treated patients with locally advanced or metastatic SCAC who have progressed on, or were ineligible for or intolerant of, platinum-based chemotherapy.

Retifanlimab (formerly INCMGA0012), an investigational intravenous PD-1 inhibitor, is currently under evaluation in registration-directed trials as a monotherapy for patients with microsatellite instability-high endometrial cancer, Merkel cell carcinoma and squamous cell carcinoma of the anal canal (SCAC); and in combination with platinum-based chemotherapy for patients with non-small cell lung cancer and SCAC.
