Krystal Biotech Receives European Commission Orphan Designation for KB407 for the Treatment of Cystic Fibrosis

PITTSBURGH, Jan. 18, 2023 (GLOBE NEWSWIRE) — Krystal Biotech, Inc. (the “Company”) (NASDAQ: KRYS), a biotechnology company focused on developing and commercializing genetic medicines for patients with rare diseases, announced today that the European Commission has granted orphan designation for KB407 for the treatment of Cystic Fibrosis (CF).

KB407 is an investigational, redosable gene therapy designed to correct the underlying cause of cystic fibrosis by delivering two copies of the CFTR gene directly to the airway epithelial cells when delivered via a nebulizer. By inducing expression of full length, normal CFTR protein in the lung, treatment with KB407 has potential to restore ion and water flow into and out of lung cells to correct the lung manifestations of the disease in patients regardless of their underlying genetic mutation.

“We are pleased that the European Commission has granted orphan drug designation to KB407, which we believe is an important step toward advancing this option to treat patients with CF,” said Suma Krishnan, President of Research and Development at Krystal Biotech.

The U.S. Food and Drug Administration has also granted Orphan Drug designation for KB407 to treat patients with CF.

About European Commission Orphan Designation

Orphan drug designation in the European Union (EU) is granted by the European Commission based on a positive opinion issued by the European Medical Association (EMA) Committee for Orphan Medicinal Products. The EMA’s orphan designation is available to companies developing treatments for life-threatening or chronically debilitating conditions that affect fewer than five in 10,000 persons in the EU. Medicines that meet the EMA’s orphan designation criteria qualify for financial and regulatory incentives that include a 10-year period of marketing exclusivity in the EU after product approval, protocol assistance from the EMA at reduced fees during the product development phase and access to centralized marketing authorization.
