VYJUVEK approved for the treatment of DEB from birth in Europe

Approval allows for dosing at home or in a healthcare setting, as well as patient or caregiver administration if deemed appropriate by a healthcare professional

PITTSBURGH, April 28, 2025 (GLOBE NEWSWIRE) -- Krystal Biotech, Inc. (the “Company”) (NASDAQ: KRYS) announced today that on April 23, 2025, the European Commission (EC) granted marketing authorization to VYJUVEK ® (beremagene geperpavec-svdt) for the treatment of wounds in patients with dystrophic epidermolysis bullosa (DEB) who have mutations in the collagen type VII alpha 1 chain ( COL7A1 ) gene, starting from birth. VYJUVEK is designed to address the genetic root cause of DEB by delivering functional copies of the human COL7A1 gene to provide wound healing and sustained functional type VII collagen protein expression with redosing. VYJUVEK is the first corrective medicine approved in Europe for the treatment of DEB. The approval granted by the EC allows for flexible VYJUVEK dosing either at home or in healthcare setting, with the option for patient or caregiver administration if deemed appropriate by a healthcare professional.

This EC decision authorizes the marketing of VYJUVEK in all European Union member states, as well as Iceland, Norway and Liechtenstein. The timing for availability of VYJUVEK in individual countries will depend on multiple factors, including the completion of reimbursement procedures. The Company is planning for its first European launch in Germany in mid-2025.

“Today’s approval is an exciting milestone for Krystal and the patients we aim to serve. After years of preparation in close coordination with leading DEB treatment centers, we are ready and excited to bring this urgently needed therapy to patients,” said Laurent Goux, Senior Vice President and General Manager of Europe at Krystal Biotech. “With already 1,000 DEB patients identified in France and Germany, as well as many more across the continent, our goal is clear – to ensure as many patients as possible are able to benefit from sustainable access to VYJUVEK.”

The EC approval follows the positive recommendation issued by the European Medicines Agency’s Committee for Medicinal Products for Human Use in February and was based on a comprehensive clinical dataset including results from the Company’s Phase 1/2 GEM-1 and Phase 3 GEM-3 studies, which collectively provided clear clinical evidence of successful COL7A1 gene delivery and durable wound closure following topical administration, and was further supported by results from the Company’s open label extension study and real-world experience in the United States.

“We are delighted that VYJUVEK has been approved in Europe as a safe and effective therapy for the many patients across Europe suffering from DEB,” said Suma Krishnan, President of Research and Development at Krystal Biotech. “This approval marks a critical milestone in our commitment to improving the lives of DEB patients around the world, and we look forward to providing patients in Europe with the first corrective medicine for this debilitating disease.”

VYJUVEK was approved by the FDA in the United States in May 2023 and is also under review for approval by Japan’s Pharmaceuticals and Medical Devices Agency with a decision expected in 2H 2025.
