EMERYVILLE, Calif., Nov. 04, 2021 (GLOBE NEWSWIRE) -- Zogenix (NASDAQ: ZGNX), a global biopharmaceutical company developing rare disease therapies, today announced financial results for the three and nine months ended September 30, 2021, and provided a corporate update. The Company will host a conference call today, Thursday, November 4, at 4:30 PM Eastern Time/1:30 PM Pacific Time.

“In the third quarter, we made significant progress against our corporate objectives in commercial operations and late-stage clinical development programs. We are pleased with the ongoing launch of FINTEPLA in the U.S. and EU and are encouraged with the positive trends that support continued adoption in Dravet syndrome. With the sNDA submitted for LGS, we are moving forward with regulatory submissions for LGS in the EU and a J-NDA in Japan for Dravet syndrome by the end of the year. We are excited to have the opportunity to potentially serve more patients who could benefit from FINTEPLA,” said Stephen J. Farr, Ph.D., President and CEO of Zogenix.

“Concurrently, we are advancing our late-stage development pipeline, notably our global Phase 3 study of FINTEPLA in CDD and concluding studies of MT1621 for the treatment of Tk2 deficiency,” concluded Dr. Farr.

Corporate Update

• FINTEPLA for the treatment of seizures associated with Dravet syndrome:
  • As of September 30, 2021, the total number of unique prescribers was 334
  • As of September 30, 2021, over 990 patients in the U.S. were prescribed FINTEPLA and referred to the REMS program
  • Continuing momentum and increasing adoption of FINTEPLA among prescribers and patients in ongoing launch in Germany and Temporary Authorization of Use in France
  • Continuing to pursue country-by-country reimbursement in Europe
  • Zogenix Access Program is now providing FINTEPLA to patients in 8 countries where the therapy is not yet commercially reimbursed
  • On track for submission of an NDA in Japan (J-NDA) to Japan’s Pharmaceutical and Medical Devices Agency by the end of 2021; received Orphan Drug Designation from the Japanese Ministry of Health, Labour & Welfare
• FINTEPLA for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS):
  • Submitted a supplemental NDA (sNDA) to the FDA in late September
  • Presented data from the interim analysis of its ongoing 12-month Phase 3 open-label extension study of FINTEPLA in LGS at the Child Neurology 2021 Annual Meeting; the results demonstrate that treatment with FINTEPLA resulted in highly statistically significant improvements in drop seizure frequency
    • Median reduction in drop seizure frequency was 39.4% at 3 months (n= 247; p<0.0001) and 51.8% for patients assessed over months 10 to 12 (n=170; p<0.0001)
    • Of the 170 patients assessed in this analysis, most (51.2%) responded with a clinically meaningful (?50%) reduction in drop seizures, while 25.3% of patients demonstrated a profound (?75%) reduction
  • Expect to submit type II variation application to Marketing Authorization in EU for approval of LGS indication in fourth quarter of 2021
  • Initiated preparations for potential U.S. commercial launch for FINTEPLA in LGS as early as first half of 2022
• FINTEPLA for the treatment of seizures associated with CDKL5 deficiency disorder (CDD):
  • On track to initiate two-arm, fixed-dose Phase 3 trial to investigate the efficacy and safety of FINTEPLA in controlling convulsive seizure frequency at a dose of 0.7 mg/kg/day in fourth quarter of 2021
  • Confirmed with FDA that a single Phase 3 study would be sufficient to support an sNDA submission, following positive meeting with FDA
• MT1621 for the treatment of thymidine kinase 2 (TK2) deficiency:
  • Updated data from Study 101, a global retrospective study of pyrimidine nucleoside substrate enhancement therapy, a fixed combination treatment of two pyrimidine nucleosides
    • Primary efficacy endpoint, an updated survival analysis using a time-dependent Cox regression model, demonstrated that the difference in probability of survival between treated patients and untreated natural history control patients was highly statistically significant (p=0.0007)
    • Vast majority of treated patients also continued to have improvements in motor, respiratory and/or feeding abilities, and the others with stabilization in these major functional domains, with many patients re-acquiring previously lost motor milestones
    • MT1621 was generally safe and well-tolerated, consistent with previously reported results
  • Recent Type B meeting with FDA confirmed planned data packages for an NDA submission based on the rare and serious nature of TK2 deficiency and the unmet medical need
  • Remaining studies continue to proceed as planned and the Company is working towards a pre-NDA meeting with FDA, ahead of the anticipated NDA submission in the second half of 2022
  • Zogenix will host a key opinion leader webinar on TK2 deficiency and MT-1621 on Monday, November 8, 2021, at 12:00 PM Eastern Time; to register for the webinar, please click here
