The Company will host a conference call today, Thursday, February 25, at 4:30 PM Eastern Time/1:30 PM Pacific Time.

"We are very pleased to have concluded 2020 with strong momentum across all of our programs, especially the robust U.S. launch of FINTEPLA^® in Dravet syndrome, where we saw strong adoption by existing and new prescribing physicians and patients, and partnerships with U.S. payors to provide optimal access for all appropriate patients," said Stephen J. Farr, Ph.D., President and CEO of Zogenix. "We expect several additional key catalysts for FINTEPLA in Dravet syndrome in the year ahead in the U.S. and in Europe, where we recently launched FINTEPLA in Germany and are actively preparing for additional European country launches and, with our partner Nippon Shinyaku, are preparing to submit a J-NDA in the second half of the year."

"Our goal is also to continue expanding the eligible patient population for FINTEPLA in other indications, based on strong safety and efficacy data from our clinical trials," continued Dr. Farr. "In the U.S. and Europe, we are advancing FINTEPLA for multiple other treatment-resistant epilepsies, including Lennox-Gastaut syndrome (LGS), for which we anticipate submitting global regulatory filings. We are also planning to initiate a Phase 3 trial for CDKL5 in the second half of 2021, and assess additional severe, treatment-resistant epilepsies through the initiation of other investigator-initiated clinical studies."
