EMERYVILLE, Calif., Nov. 07, 2019 (GLOBE NEWSWIRE) -- Zogenix, Inc. (NASDAQ: ZGNX), a global pharmaceutical company developing rare disease therapies, today announced financial results for the three and nine months ended September 30, 2019, and provided a corporate update. The Company will host a conference call today, Thursday, November 7, at 4:30 PM Eastern Time/1:30 PM Pacific Time.

“We were pleased to resubmit the New Drug Application (NDA) for FINTEPLA® for the treatment of seizures associated with Dravet syndrome to the U.S. Food and Drug Administration (FDA) in late September, and we expect to hear from the FDA regarding the filing status of our NDA submission shortly,” said Stephen J. Farr, Ph.D., President and CEO of Zogenix. “Following completion of enrollment in our program for FINTEPLA for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS) in July, we remain on track to announce top-line safety and efficacy results in the first quarter of 2020.”

“In addition, we were very excited to announce the acquisition of Modis Therapeutics and add a novel, late-stage clinical candidate, MT1621, for the treatment of patients with Thymidine Kinase 2 deficiency (TK2d), to our rare disease pipeline,” continued Dr. Farr. “Last month, safety and positive efficacy data from a global, retrospective Phase 2 study supporting the potential of MT1621 to significantly alter the course of TK2d, an often-fatal mitochondrial DNA depletion disorder, were presented.”

Third quarter 2019 Financial Results

• The Company recorded $0.6 million in revenue for the third quarter ended September 30, 2019, as a result of its March 2019 collaboration with Nippon Shinyaku Co., Ltd. for FINTEPLA in Dravet syndrome and LGS in Japan. Zogenix recorded no revenue for the corresponding period of 2018.
   
• Research and development expenses for the third quarter ended September 30, 2019, totaled $28.4 million, up from $27.6 million in the third quarter ended September 30, 2018, as the Company concluded Phase 3 clinical trials in Dravet syndrome and expanded clinical trial activities related to its ongoing Phase 3 development program of FINTEPLA in LGS.
   
• Selling, general and administrative expenses for the third quarter ended September 30, 2019, totaled $15.8 million, compared with $11.0 million in the third quarter ended September 30, 2018.

The increase in net loss was primarily attributable to $249.4 million of acquired in-process research and development consisting of existing research and development projects at the time of the Modis acquisition.

Nine months Ended September 30, 2019 Financial Results Compared to Nine months Ended September 30, 2018

About Zogenix
Zogenix is a global pharmaceutical company committed to developing and commercializing transformative therapies to improve the lives of patients and their families living with rare diseases. The company has two late-stage development programs underway: FINTEPLA® (ZX008, fenfluramine) for the treatment of seizures associated with Dravet and Lennox-Gastaut syndromes, two rare and often-catastrophic childhood-onset epilepsies, and MT1621, a combination deoxynucleoside substrate enhancement therapy for the treatment of TK2 deficiency, a rare, debilitating, and often fatal genetic disorder that primarily affects infants and children and for which there are currently no approved therapies.  Zogenix recently resubmitted its New Drug Application for FINTEPLA for Dravet syndrome to the U.S. Food & Drug Administration; its application for FINTEPLA for Dravet syndrome is under review by the European Medicines Agency. Zogenix expects top-line data from its Phase 3 study of FINTEPLA in Lennox-Gastaut syndrome in the first quarter of 2020. FINTEPLA is also in development in Japan. Zogenix acquired Modis Therapeutics and the MT1621 program in September 2019.

You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and Zogenix undertakes no obligation to revise or update this press release to reflect events or circumstances after the date hereof.
