EMERYVILLE, Calif., May 05, 2020 (GLOBE NEWSWIRE) -- Zogenix, Inc. (Nasdaq: ZGNX), a global pharmaceutical company developing rare disease therapies, today announced financial results for the three months ended March 31, 2020, and provided a corporate update. The Company will host a conference call today, Tuesday, May 5, at 4:30 PM Eastern Time/1:30 PM Pacific Time.

“We continue to make progress on several key initiatives to support Zogenix’s growth and transition to a commercial-stage company,” said Stephen J. Farr, Ph.D., President and CEO of Zogenix. “During the pandemic, our priority has been to ensure that the approximately 530 Dravet syndrome patients currently taking FINTEPLA® in our clinical studies and expanded access program continue to receive this investigational product. As we approach the June 25^th PDUFA date for FINTEPLA in Dravet syndrome, we continue to support the FDA’s review of our application and advance our commercial preparations in parallel. Our plans now also address potential ongoing pandemic-related circumstances that could impact how we launch FINTEPLA, if approved, in the third quarter.

“Recently, we were very pleased to share additional compelling clinical efficacy and safety data from an interim analysis of our ongoing open-label extension (OLE) study in Dravet syndrome,” continued Dr. Farr. “These data demonstrated significant, lasting and clinically meaningful reductions in convulsive seizure frequency in patients after up to two years of treatment with FINTEPLA.”

“Following positive top-line results from our global pivotal Phase 3 trial (Study 1601) of FINTEPLA in Lennox-Gastaut syndrome (LGS), a notoriously difficult to treat rare epilepsy, we are now focused on finalizing the studies and data required to support a supplemental NDA (sNDA) and intend to meet with the FDA later this year to discuss our planned submission,” concluded Dr. Farr.
