Item 8.01 Other Events.

On June 25, 2020, Zogenix, Inc. (the “Company”) announced that the U.S. Food and Drug Administration (“FDA”) has approved FINTEPLA (fenfluramine) oral solution, CIV for the treatment of seizures associated with Dravet syndrome in patients two years of age and older. FINTEPLA will be launched through a restricted distribution program, called the FINTEPLA Risk Evaluation and Mitigation Strategy (“REMS”) Program, and is expected to be available through Zogenix’s specialty pharmacy partner by the end of July 2020.

The FDA’s approval of FINTEPLA in Dravet syndrome was based on data from two randomized, double-blinded, placebo-controlled Phase 3 clinical trials, published in The Lancet (Volume 394, Issue 10216, P2243-2254, December 21, 2019) and JAMA Neurology (2020 Mar; 77(3): 300–308), and safety data from an open-label extension trial in which many patients received FINTEPLA for up to three years. When added to existing treatment regimens, FINTEPLA significantly reduced the monthly convulsive seizure frequency compared to placebo in study patients whose seizures were not adequately controlled on one or more antiepileptic drugs. In addition, most study patients responded to treatment with FINTEPLA within three to four weeks and effects remained consistent over the treatment period.

FINTEPLA will be available to certified prescribers in the U.S. in July 2020. Zogenix is launching Zogenix Central™, a comprehensive support service that will provide ongoing product assistance to patients, caregivers, and their medical teams.

As a result of the FDA approval of FINTEPLA, the Company will pay a milestone of $15.0 million pursuant to the sale and purchase agreement with Brabant Pharma Limited, dated October 24, 2014.
