Zogenix Submits Fintepla Applications to the FDA and EMA for the Treatment of Dravet Syndrome

EMERYVILLE, Calif., Feb. 06, 2019 (GLOBE NEWSWIRE) — Zogenix, Inc. (NASDAQ:ZGNX), a global pharmaceutical company developing rare disease therapies, today announced it has completed its rolling submission of a New Drug Application (NDA) to the U.S. Food & Drug Administration (FDA) and submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for FINTEPLA (ZX008, low-dose fenfluramine) for the treatment of seizures associated with Dravet syndrome. Dravet syndrome is an intractable and difficult-to-treat epilepsy that begins in infancy and is associated with frequent, severe, and potentially life-threatening seizures, developmental delay, and cognitive impairment.i,ii

Both applications are based on data from two pivotal Phase 3 trials in Dravet syndrome and an interim analysis from an ongoing open-label extension study, which included 232 patients treated for up to 21 months.

“Our concurrent submissions to the FDA and EMA are the culmination of four years’ effort for Zogenix, our investigators, and the families who participated in the ZX008 clinical trial program,” said Stephen J. Farr, President and Chief Executive Officer of Zogenix. “We are honored to have partnered with such dedicated people to develop a potential new treatment for this rare and often catastrophic disease and look forward to working closely with the FDA and EMA during the review process.”

Zogenix is also investigating FINTEPLA in Lennox-Gastaut syndrome, another rare childhood-onset epilepsy, for which a Phase 3 trial is ongoing.
