EMA to Review Cemiplimab as a Potential Treatment for Advanced Cutaneous Squamous Cell Carcinoma

Regeneron Pharmaceuticals, Inc. and Sanofi today announced that the European Medicines Agency (EMA) has accepted for review the Marketing Authorization Application (MAA) for cemiplimab for the treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or patients with locally advanced CSCC who are not candidates for surgery. Advanced CSCC is the deadliest non-melanoma skin cancer. Cemiplimab is an investigational human monoclonal antibody targeting the checkpoint inhibitor PD-1 (programmed cell death protein-1).
The MAA for cemiplimab is based on a Phase 2 pivotal, single-arm, open-label clinical trial of cemiplimab for advanced CSCC (EMPOWER-CSCC 1) in addition to Phase 1 data from two advanced CSCC expansion cohorts. Both clinical trials enrolled patients with metastatic CSCC and patients with locally advanced CSCC who were not candidates for surgery. Topline results from EMPOWER-CSCC 1 were previously announced in December 2017, and Phase 1 expansion cohort results were presented at the 2017 American Society of Clinical Oncology Annual Meeting. Updated results from both clinical trials are being submitted for presentation at upcoming medical congresses.

Cemiplimab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement, and was invented by Regeneron using the company’s proprietary VelocImmune® technology that yields optimized fully-human antibodies.

Cemiplimab is currently under clinical development, and its safety and efficacy has not been fully evaluated by any regulatory authority.
