Krystal Biotech Receives FDA Approval for the First-Ever Redosable Gene Therapy, VYJUVEK (beremagene geperpavec-svdt) for the Treatment of Dystrophic Epidermolysis Bullosa - Seite 2

“This is a devastating disease,” said M. Peter Marinkovich, M.D., primary investigator of the GEM-3 trial, Director of the Blistering Disease Clinic at Stanford Health Care and Associate Professor of Dermatology at the Stanford University School of Medicine. “Until now, doctors and nurses had no way to stop blisters and wounds from developing on dystrophic EB patient skin and all we could do was to give them bandages and helplessly watch as new blisters formed. VYJUVEK topical gene therapy changes all of this. VYJUVEK both heals patient wounds and prevents skin from re-blistering because it actually corrects the underlying skin defect of dystrophic EB. Because it’s safe and easy to apply directly to wounds, it doesn't require a lot of supporting technology or specialized expertise, making VYJUVEK highly accessible even to patients who live far away from specialized centers."

The FDA approval of VYJUVEK is based on two clinical studies. The GEM-1/2 trial was an intra-patient, open label, single center, randomized, placebo-controlled study showing that repeat topical applications of VYJUVEK were associated with durable wound closure, full-length cutaneous COL7 expression, and anchoring fibril assembly with minimal reported adverse events. The GEM-3 trial was an intra-patient, double-blinded, multi-center, randomized, placebo-controlled study that met both its primary endpoint of complete wound healing at six months and its key secondary endpoint of complete wound healing at three months. VYJUVEK was well tolerated with no drug-related serious adverse events or discontinuations due to treatment-related events.

“Data from our GEM-1/2 trial and our GEM-3 trial, published in Nature Medicine and the New England Journal of Medicine, respectively, demonstrated the strength of both studies showing that VYJUVEK safely and effectively improved wound healing,” said Suma Krishnan, President, Research & Development, Krystal Biotech, Inc. “For so many years, all we have been able to offer DEB patients was palliative care, but now, based on the strength of the Company’s clinical trial data, there is a safe and effective FDA approved treatment.”

“Today’s landmark approval of VYJUVEK as the first redosable gene therapy ushers in a whole new paradigm to treat genetic diseases and is an important milestone for patients affected by DEB as well as their families and caregivers," said Krish S. Krishnan, Chairman and Chief Executive Officer of Krystal Biotech, Inc. "We offer our sincere gratitude to DEB patients, caregivers, investigators, US regulators, and our employees who made this approval possible. For Krystal, this is a transformative achievement that highlights our commitment to developing and commercializing novel therapies for patients with rare diseases and demonstrates Krystal’s capability as a fully-integrated company ready to launch and bring VYJUVEK to patients as quickly as possible and deliver additional transformative medicines to patients as we advance our pipeline.”
