Zogenix Resubmits New Drug Application for FINTEPLA® for the Treatment of Dravet Syndrome to U.S. Food and Drug Administration


EMERYVILLE, Calif., Sept. 26, 2019 (GLOBE NEWSWIRE) -- Zogenix, Inc. (NASDAQ: ZGNX), a global pharmaceutical company developing rare disease therapies, today announced that it has resubmitted its New Drug Application (NDA) for FINTEPLA® (ZX008, fenfluramine) for the treatment of seizures associated with Dravet syndrome to the U.S. Food and Drug Administration (FDA).

“We believe that FINTEPLA, if approved, could become an important new treatment option for patients and families living with Dravet syndrome,” said Stephen J. Farr, Ph.D., President and CEO of Zogenix. “We appreciate the FDA’s guidance through the resubmission process and look forward to continuing to work closely with the Agency during their review of our application.”

The NDA is 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 24 months.  Zogenix is also investigating FINTEPLA in Lennox-Gastaut syndrome, another rare childhood-onset epilepsy, for which a Phase 3 trial is ongoing and top-line data are anticipated in the first quarter of 2020.
