Zogenix Review Extension for Dravet Syndrome Drug
FDA has extended by three months its review of a Zogenix NDA for Fintepla (fenfluramine oral solution) for treating seizures associated with Dravet syndrome. The new user fee review action target date is 6/25.
The extension allows the agency time to review additional data submitted by Zogenix in response to a recent information request, the company says. FDA determined that the information submission constituted a major amendment to the NDA, necessitating the review extension.
The NDA was originally accepted 11/2019 and included data from two positive 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.
