PITTSBURGH, Aug. 07, 2023 (GLOBE NEWSWIRE) -- Krystal Biotech, Inc. (the “Company”) (NASDAQ: KRYS), a commercial-stage biotechnology company focused on the discovery, development and commercialization of genetic medicines to treat diseases with high unmet medical needs, today reported financial results and key operational progress updates for the second quarter ended June 30, 2023.

“2023 is off to a very strong start and we expect the momentum to continue for the rest of the year. In the first half of the year, we received FDA approval for VYJUVEK, dosed our first patient in the cystic fibrosis trial and obtained IND clearance for our first oncology candidate,” said Krish S. Krishnan, Chairman and CEO of Krystal Biotech. “I am particularly thrilled with the enthusiasm that physicians and patients are expressing for VYJUVEK in these early days of launch. With 121 Patient Start Forms in the first six weeks since approval, I am pleased with the initial pace of the launch, and we look forward to promptly initiating treatment for these patients.”

• On May 19, the Company announced that VYJUVEK (beremagene geperpavec-svdt, or B-VEC) was approved by the U.S. Food & Drug Administration (FDA) for the treatment of patients six months of age or older with either recessive or dominant dystrophic epidermolysis bullosa (DEB) to be administered by a healthcare professional either in a healthcare professional setting (e.g., clinic) or a home setting.
• As of June 30, the Company received 121 Patient Start Forms of which 30 start forms were generated for patients with dominant dystrophic epidermolysis bullosa. The Company will continue to report on the number of Patient Start Forms submitted to the Company for the first three quarters following VYJUVEK approval and will transition to reporting on the number of Patients on Therapy beginning in the first quarter of 2024.
• The Company also received positive coverage determinations from several of the national health plans, including UnitedHealthcare, as well as regional plans such as BlueCross BlueShield, state Medicaid plans and other smaller regional health plans. The Company expects that additional payer policies will continue to publish that cover VYJUVEK for both recessive and dominant DEB patients.
• In July, the Company received a positive opinion from the European Medical Agency (EMA) on the Pediatric Investigation Plan for B-VEC for the treatment of DEB with no additional studies required. The Company plans to submit a market authorization application to the EMA in the second half of 2023 and anticipates a potential launch in the EU in the second half of 2024.
• In July, the Pharmaceuticals and Medical Agency in Japan accepted the open label extension study of B-VEC, and the Company intends to start an open label extension study of B-VEC in Japan in the second half of 2023 and file for approval in Japan in 2024.

About VYJUVEK

VYJUVEK is a non-invasive, topical, redosable gene therapy designed to deliver two copies of the COL7A1 gene when applied directly to DEB wounds. VYJUVEK 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.

Indication

VYJUVEK is a herpes-simplex virus type 1 (HSV-1) vector-based gene therapy indicated for the treatment of wounds in patients six months of age and older with dystrophic epidermolysis bullosa with mutation(s) in the collagen type VII alpha 1 chain (COL7A1) gene.
