Jazz Pharmaceuticals updates Phase 3 trial of cannabidiol oral solution

Jazz Pharmaceuticals announced top-line results from the Phase 3 open-label, single-arm trial in Japan evaluating the safety and efficacy of cannabidiol oral solution as an adjunctive treatment for seizures associated with Lennox-Gastaut syndrome, Dravet syndrome or tuberous sclerosis complex. The trial did not meet the primary efficacy endpoint of a pre-specified percentage change in indication-associated seizure frequency during the treatment period 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.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. “We are continuing to collect data in Japanese patients and plan to engage with regulatory authorities in Japan regarding a potential new drug application (JNDA). We recognize the significant unmet need for patients in Japan living with rare epilepsies and thank the investigators, patients and caregivers who are involved in this trial.”
