DUBLIN , Aug. 22, 2024 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ ) today announced top-line results from the Phase 3 open-label, single-arm trial in Japan evaluating the safety and efficacy of cannabidiol oral solution (marketed as Epidiolex ® /Epidyolex ® globally) as an adjunctive treatment for seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS) or tuberous sclerosis complex (TSC). The trial did not meet the primary efficacy endpoint of a pre-specified percentage change in indication-associated seizure frequency during the treatment period (up to 16 weeks) compared to baseline in Japanese pediatric patients; however, numeric improvements were observed in the primary and several secondary endpoints.
No new safety signals were observed in the trial. "We are confident in the overall clinical profile of Epidyolex , which has been established in five Phase 3 clinical trials in more than 900 patients. We believe the totality of the Epidyolex global data, including the findings from this trial, supports advancement of the program in Japan ," said Rob Iannone , M.
