Zogenix Completes Enrollment in Phase 3 Trial of FINTEPLA® in Lennox-Gastaut Syndrome

1050 Days ago

EMERYVILLE, Calif., July 08, 2019 (GLOBE NEWSWIRE) -- Zogenix, Inc. (NASDAQ: ZGNX), a global pharmaceutical company developing rare disease therapies, today announced that it has completed enrollment for, and randomized the last patient into the treatment period of, Study 1601, the Company’s Phase 3 clinical trial of its lead investigational therapy, FINTEPLA® (ZX008, fenfluramine), for the treatment of seizures associated with Lennox-Gastaut Syndrome (LGS), a severe and often treatment-resistant childhood-onset epilepsy.

“We have been extremely pleased with the rate of enrollment in this trial and look forward to the availability of top-line safety and efficacy data in the first quarter of 2020,” said Gail M. Farfel, Ph.D., Executive Vice President and Chief Development Officer of Zogenix.  “Based on the compelling data generated in the previously completed Phase 2 study, we believe this promising drug candidate has the potential to become an important new treatment option for the control of seizures in patients suffering from LGS.”

Study 1601 is a multi-national, randomized, double-blind, placebo-controlled trial of two fixed doses of FINTEPLA as adjunctive therapy for seizures in children and adults with LGS.  After establishing a baseline seizure frequency for four weeks, patients are randomized into one of three treatment groups (0.2 or 0.8 mg/kg/day FINTEPLA, maximum of 30 mg/day, or placebo) for a two-week period of dose titration before being held at a fixed dose for 12 weeks of maintenance treatment.  The study randomized a total of 263 patients, with approximately 87 subjects per group.  The primary endpoint of the clinical trial is the 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 compared to placebo.  The key secondary endpoints include change in the number of drop seizures between baseline and the combined titration and maintenance periods at the 0.2 mg/kg/day dose compared to placebo, and the proportion of patients achieving a 50% reduction in drop seizures.  Patients who complete the maintenance treatment period may be eligible to enter a 12-month open-label extension to evaluate the long-term safety, tolerability and effectiveness of FINTEPLA in LGS.

FINTEPLA for the treatment of LGS has previously been designated as an orphan drug by both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency.
