PHILADELPHIA, July 20, 2017 (GLOBE NEWSWIRE) -- Spark Therapeutics (NASDAQ:ONCE), a fully integrated gene therapy company dedicated to challenging the inevitability of genetic disease, announced today that the Offices of Orphan Products Development and Pediatric Therapeutics of the U.S. Food and Drug Administration (FDA) have designated investigational LUXTURNATM (voretigene neparvovec) as a drug for a rare pediatric disease. Under FDA's Rare Pediatric Disease Priority Review Voucher program, companies who receive approval for a new drug application or Biologics License Application (BLA) for a rare pediatric disease may be eligible to receive a voucher for a Priority Review of a subsequent marketing application for a different product. The Priority Review Voucher may be used by the company or sold to a third party.
FDA’s Office of Tissues and Advanced Therapies currently is reviewing the BLA for LUXTURNA for the treatment of patients with vision loss due to confirmed biallelic RPE65 mutation-associated retinal dystrophy under a Priority Review designation with a Prescription Drug User Fee Act (PDUFA) action date of Jan. 12, 2018.
LUXTURNA has the potential to be both the first pharmacologic treatment for an inherited retinal disease (IRD) and the first gene therapy for a genetic disease approved in the United States. A natural history study has shown that people with this IRD eventually progress to complete blindness.
About Spark Therapeutics
Spark Therapeutics, a fully integrated company, strives to challenge the inevitability of genetic disease by discovering, developing, and delivering gene therapies that address inherited retinal diseases (IRDs), neurodegenerative diseases, as well as diseases that can be addressed by targeting the liver. Our validated platform successfully has delivered proof-of-concept data with investigational gene therapies in the retina and liver. Our most advanced investigational candidate, with proposed trade name LUXTURNA™ (voretigene neparvovec), is currently under Priority Review with FDA for the treatment of biallelic RPE65-mediated IRD and has been designated for a rare pediatric disease. It previously received breakthrough therapy and orphan product designations from FDA and orphan product designations from the European Medicines Agency (EMA). The pipeline also includes SPK-7001 in a Phase 1/2 trial for choroideremia, and two hemophilia development programs: SPK-9001 (which also has received both breakthrough therapy and orphan product designations by FDA, and access to the PRIority MEdicines (PRIME) Program by the EMA) in a Phase 1/2 trial for hemophilia B being developed in collaboration with Pfizer, and SPK-8011, in a Phase 1/2 trial for hemophilia A to which Spark Therapeutics retains global commercialization rights.
