Item 8.01
Other Events.

On November 29, 2017, Zogenix, Inc. (the “Company”) announced that the first child has enrolled in the Phase 3 clinical trial for the Company’s lead investigational therapy, ZX008, as an adjunctive treatment of seizures associated with Lennox-Gastaut syndrome (“LGS”).

The Phase 3 multicenter global LGS trial is divided in two parts. Part 1 is a double-blind, placebo-controlled investigation to assess the safety, tolerability and efficacy of ZX008, low-dose fenfluramine, when added to a patient’s current anti-epileptic therapy. The trial will include two dose levels of ZX008 (0.2 mg/kg/day and 0.8 mg/kg/day, up to a maximum daily dose of 30 mg), as well as placebo. After establishing baseline seizure frequency for 4 weeks, randomized patients will be titrated to their dose over a 2-week titration period, followed by a 12-week fixed dose maintenance period. The Company is targeting a total of 225 patients (75 per treatment arm) in the trial. The primary endpoint of the clinical trial is change in the number of seizures that result in drops between baseline and the combined titration and maintenance periods at the 0.8 mg/kg/day dose. The key secondary endpoints include change in the number of seizures that result in drops between baseline and the combined titration and maintenance periods at the 0.2 mg/kg/day dose, and the proportion of patients achieving a 50 percent reduction in drop seizures. Part 2 of the clinical trial will be a 12-month open-label extension to evaluate the long-term safety, tolerability and effectiveness of ZX008.

The initiation of this Phase 3 program follows a Phase 2 open-label, dose-finding investigator-initiated clinical trial of ZX008 for the treatment of LGS that was conducted by Lieven Lagae, M.D., Ph.D., Professor at the University of Leuven, Belgium, Head of the Pediatric Neurology Department. The interim Phase 2 results were presented at the 70th Annual Meeting of the American Epilepsy Society in December 2016. Of the 13 subjects enrolled, seven (54 percent) achieved at least a 50 percent reduction in the number of major motor seizures, with a range of 50 percent to 90 percent improvement. In addition, there was an approximately 2-fold increase in the number of responders (with a reduction of 50 percent or greater) on a dose of 0.4 mg/kg/day vs. 0.2 mg/kg/day. Importantly, per protocol, dose escalation stopped when a patient’s major motor seizure frequency was reduced by ≥50 percent of baseline.

ZX008 for the treatment of LGS has previously been designated as an orphan drug by both the U.S. Food and Drug Administration and the European Commission. The Phase 3 trial is planned for up to 85 sites in North America, Europe, Asia-Pacific, South America, South Africa and Australia.

Forward Looking Statements

The Company cautions you that statements included in this report that are not a description of historical facts are forward-looking statements. Words such as “believes,” “anticipates,” “plans,” “expects,” “indicates,” “will,” “intends,” “potential,” “suggests,” “assuming,” “designed” and similar expressions are intended to identify forward-looking statements. These statements are based on the Company's current beliefs and expectations. These forward-looking statements include statements regarding the Phase 3 clinical trial in Lennox-Gastaut syndrome, including the number of patients to be enrolled. The inclusion of forward-looking statements should not be regarded as a representation by the Company that any of its plans will be achieved. Actual results may differ from those set forth in this release due to the risks and uncertainties inherent in the Company’s business, including, without limitation: the uncertainties associated with the clinical development and regulatory approval of product candidates such as ZX008, including potential delays in the commencement, enrollment and completion of clinical trials; the Company’s reliance on third parties to conduct its clinical trials, enroll patients, manufacture its preclinical and clinical drug supplies and manufacture commercial supplies of its drug products, if approved; unexpected adverse side effects or inadequate therapeutic efficacy of ZX008 in LGS that could limit approval and/or commercialization, or that could result in recalls or product liability claims; the Company’s ability to fully comply with numerous federal, state and local laws and regulatory requirements, as well as rules and regulations outside the United States, that apply to its product development activities; and other risks described in the Company’s prior press releases as well as in public periodic filings with the Securities and Exchange Commission.
