Jazz Pharmaceuticals Announces Initiation of Phase 3 Trial Evaluating Epidiolex®/Epidyolex® (cannabidiol) for Patients with Epilepsy with Myoclonic-Atonic Seizures
Jazz Pharmaceuticals has initiated a Phase 3 trial to study the safety and efficacy of Epidiolex (cannabidiol) for treating Epilepsy with Myoclonic-Atonic Seizures (EMAS). This is the first randomized, controlled trial focusing on this condition among children and adolescents. The trial will follow a double-blind, placebo-controlled design over 14 weeks, involving participants aged 1-18 from 30 global sites. Currently, Epidiolex is not approved for EMAS in the U.S. or EU. The study aims to address the need for effective treatments for treatment-resistant epilepsy syndromes.
- Initiation of a Phase 3 trial for Epidiolex, targeting a significant unmet need in treating EMAS.
- The trial involves multiple global sites, potentially increasing exposure and data collection.
- Epidiolex is not yet approved for EMAS in the U.S. or EU, indicating potential regulatory hurdles ahead.
Trial is the first randomized, controlled clinical trial evaluating cannabidiol to treat children and adolescents living with a developmental and epileptic encephalopathy known as Epilepsy with Myoclonic-Atonic Seizures
DUBLIN, Aug. 18, 2022 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced it has initiated a new Phase 3 trial to investigate the efficacy and safety of Epidiolex® (cannabidiol), known as Epidyolex® in Europe, in children and adolescents with Epilepsy with Myoclonic-Atonic Seizures (EMAS). The randomized, double-blind, placebo-controlled study will investigate EMAS-associated seizure frequency over the 14-week treatment period compared to baseline. The Company's cannabidiol is not currently approved in the United States or European Union for the treatment of EMAS.
EMAS – also known as Myoclonic Astatic Epilepsy (MAE) or Doose Syndrome – is a developmental and epileptic encephalopathy that begins in early childhood. EMAS accounts for between one and two percent of all childhood-onset epilepsies.1 Seizures in children with EMAS are often difficult to treat and may not respond well to medication.2
"Given there are numerous treatment-resistant epilepsy syndromes, epileptologists often look for efficacy by seizure type, most of which have no syndrome-specific approved treatment. An EMAS indication would provide support for the use of Epidiolex in a fourth indication of a distinct, generalized seizure type, myoclonic-atonic seizures," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "Jazz is committed to continuing to generate clinical study data and real-world evidence to further support the utility of the Company's cannabidiol across a broad range of difficult-to-treat seizure types."
The Phase 3 pivotal trial GWEP20238 (NCT05288283) will be run in two parts and will enroll children and adolescent participants (ages 1-18) at 30 global sites. Part A will assess efficacy and safety of cannabidiol compared to placebo as an adjunctive treatment for children and adolescents with myoclonic-atonic seizures. Upon completion of Part A, participants will have an option to continue in a 54-week open-label extension (Part B).
The Phase 3 trial was initiated based on preliminary data from our clinical development program, including real-world evidence, that supports cannabidiol as an effective therapy for the treatment of myoclonic-atonic-associated seizures.
EPIDIOLEX®/EPIDYOLEX® (cannabidiol), is a prescription, plant-derived cannabis-based medicine administered as an oral solution which contains highly purified cannabidiol (CBD). Cannabidiol, the active ingredient in EPIDIOLEX, is a cannabinoid that naturally occurs in the Cannabis sativa L. plant. The precise mechanisms by which EPIDIOLEX exerts its anticonvulsant effect in humans are unknown.
