Krystal Biotech, Inc. (“Krystal”) (NASDAQ: KRYS), the leader in redosable gene therapies, today announced that it plans to offer patients with dystrophic epidermolysis bullosa (DEB), who are enrolled in the GEM-3 open label extension study, the opportunity to be dosed in their homes by a health care professional (HCP). Krystal is offering this convenience to patients based on feedback from the U.S. Food and Drug Administration (FDA) following review of Krystal’s human factors (HF) validation study report submitted in January 2022.

“We thank the Agency for their consideration and believe that dosing patients in the comfort of their homes relieves them from an undue burden of travel and improves compliance with the therapy,” said Suma Krishnan, Founder and President of Research & Development at Krystal.

Next Steps

Per the FDA’s guidance, Krystal plans to address the convenience of dosing a patient at home of our intend-to-market B-VEC commercial product in its BLA submission that is anticipated in 2Q, 2022.

About the GEM-3 OLE Study

The GEM-3 B-VEC OLE study is a 78-week (approximately a year and a half) open-label extension study of B-VEC for participants diagnosed with DEB who are aged 6 months and older that began in May 2021. The primary endpoint will be to assess long term safety and tolerability of the topical gene therapy. The study will enroll subjects who participated in GEM-3 Phase III study, as well as new participants who were unable to participate in the Phase III study and who meet all enrollment criteria.

About B-VEC

B-VEC is an investigational non-invasive, topical, redosable gene therapy designed to deliver two copies of the COL7A1 gene when applied directly to DEB wounds. B-VEC was designed to treat DEB at the molecular level by providing the patient’s skin cells the template to make normal COL7 protein, thereby addressing the fundamental disease-causing mechanism.

The FDA and EMA have each granted B-VEC orphan drug designation for the treatment of DEB, and the FDA has granted B-VEC fast track designation and rare pediatric designation for the treatment of DEB. In addition, in 2019, the FDA granted Regenerative Medicine Advanced Therapy (RMAT) to B-VEC for the treatment of DEB and the EMA granted PRIority MEdicines (PRIME), eligibility for B-VEC to treat DEB.
