Why Are Zogenix's Shares Gaining Today?

The FDA has granted Priority Review to Zogenix Inc's ZGNX supplemental marketing application seeking approval for Fintepla (fenfluramine) in Lennox-Gastaut syndrome (LGS) childhood-onset epilepsy.

• The agency's Prescription Drug User Fee Act (PDUFA) target action date is March 25, 2022. 
• The submission is based on data from the Phase 3 trial that demonstrated Fintepla at a dose of 0.7/mg/kg/day was superior to placebo in reducing the frequency of drop seizures (p=0.0012), as well as long-term safety and effectiveness data from Zogenix's ongoing open-label extension trials.
