Iovance Biotherapeutics Completes Biologics License Application (BLA) Submission for Lifileucel in Advanced Melanoma

First TIL Therapy BLA Submission to U.S. Food and Drug AdministrationSAN CARLOS, Calif., March 24, 2023 (GLOBE NEWSWIRE) — Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today announced it has completed its rolling Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA) for lifileucel. Lifileucel is a tumor infiltrating lymphocyte (TIL) therapy intended as a treatment for patients with advanced (unresectable or metastatic) melanoma who progressed on or after prior anti-PD-1/L1 therapy and targeted therapy, where applicable. There are no FDA approved therapies in this treatment setting. Frederick Vogt, Ph.D., J.D., Interim President and Chief Executive Officer of Iovance, stated, “Completing our BLA submission for lifileucel is a critical step forward in our journey to deliver the first individualized, one-time cell therapy for a solid tumor. I would like to acknowledge the patients and physicians who participated in the C-144-01 clinical trial and the FDA review team for their commitment and support, as well as our internal team for their tremendous effort in completing the first BLA submission for Iovance. Our preparations for commercialization remain on track to support a launch later this year. We look forward to continued collaboration with the FDA as they review this new class of treatment for advanced melanoma patients with limited options.” The BLA submission for lifileucel is supported by positive clinical data from the C-144-01 clinical trial in patients with advanced post-anti-PD1 melanoma. Following a successful pre-BLA meeting with the FDA, Iovance is pursuing accelerated approval in this indication. Iovance also reached agreement with the FDA regarding the registrational trial design for the Phase 3 TILVANCE-301 trial of lifileucel in combination with pembrolizumab in frontline advanced melanoma. TILVANCE-301 is intended to support full approval of lifileucel in post-anti-PD-1 advanced melanoma and is also designed to support registration for lifileucel in combination with pembrolizumab as therapy for advanced melanoma in the frontline setting. Startup activities for TILVANCE-301 are ongoing and the trial is expected to be well underway at the time of potential accelerated approval for lifileucel in advanced post-anti-PD-1 melanoma. Marc Hurlbert, Ph.D., CEO of the Melanoma Research Alliance (MRA), said, “MRA congratulates Iovance for completing the BLA submission and moving closer toward making TIL therapy an option for people with advanced melanoma who have progressed following prior treatments. We hope for an FDA approval as quickly as possible for patients with significant unmet need who have no approved treatment options.” Following receipt of the complete rolling BLA submission for lifileucel, the FDA has 60 days to determine the acceptability of the BLA for review. The rolling BLA allowed Iovance to submit portions of the BLA to the FDA on an ongoing basis, enabling the FDA to begin review as early as possible as documents were received. The rolling BLA submission and eligibility for priority review are benefits available under the FDA’s guidance on expedited programs for serious conditions, which allow for an expedited six-month review from the time of BLA acceptance. In addition, the FDA previously granted a regenerative medicine advanced therapy (RMAT) designation for lifileucel in advanced melanoma. About Iovance Biotherapeutics, Inc.
