B-VEC (beremagene geperpavec) for Dystrophic Epidermolysis Bullosa (DEB)

• On January 5, 2023, the Company was notified by the U.S. Food & Drug Administration (FDA) that the Prescription Drug User Fee Act (PDUFA) date for the Company’s Biologics License Application (BLA) for B-VEC for the treatment of patients with DEB, will be May 19, 2023 and that proposed labeling discussions would begin no later than April 20, 2023. All clinical and manufacturing inspections conducted by the FDA as part of the BLA review process are now successfully complete.
• In December 2022, the results of the B-VEC pivotal Phase 3 GEM-3 trial were published in the New England Journal of Medicine (NEJM). The GEM-3 trial was a randomized, double-blind, intra-patient, placebo-controlled, multi-center study designed to evaluate the efficacy and safety of B-VEC for the treatment of DEB. Two editorials were also published in the same issue of NEJM on the GEM-3 trial.
• The Company submitted a request for Marketing Authorization Application (MAA) with the European Medicines Agency (EMA) in November 2022 for B-VEC for the treatment of DEB in patients 6 months and older. The Company was informed by the EMA in January 2023 to modify the PIP waiver request to include patients between birth and 6 months. The Company is modifying the application so that the MAA procedure can officially start in the second half of 2023 with an approval expected in early 2024.
