GW Pharmaceuticals PLC- ADR (NASDAQ:GWPH), a biopharmaceutical company focused on discovering, developing and commercializing novel therapeutics from its proprietary cannabinoid product platform, today announced that the Company has selected infantile spasms (IS) as the fourth target indication for its Epidiolex orphan pediatric epilepsy development program. In addition, the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for Epidiolex (cannabidiol or CBD) for the treatment of IS. GW expects to commence a two-part pivotal Phase 3 study in the fourth quarter of 2016.

Epidiolex is already being developed in three other orphan indications within the field of pediatric epilepsy – Dravet syndrome, Lennox-Gastaut syndrome (LGS) and Tuberous Sclerosis Complex (TSC). In March 2016, GW announced positive results from the first Phase 3 trial in Dravet syndrome. Results of the first Phase 3 trial in LGS are expected in June 2016.

“We are pleased to add infantile spasms as a fourth target indication for Epidiolex, demonstrating GW’s ongoing commitment to addressing the significant unmet medical need within the field of pediatric epilepsy,” stated Justin Gover, CEO of GW Pharmaceuticals . “Currently, there are limited treatment options for children suffering from infantile spasms and outcomes for patients with the disorder include higher mortality, ongoing development of additional seizure disorders as the patient matures, and often severe cognitive and developmental delay.”

An infantile spasm is a specific type of seizure seen in an epilepsy syndrome of infancy and childhood known as West Syndrome. The onset of infantile spasms usually occur in the first year of life, typically between 4-8 months of age. The condition constitutes 2 percent of childhood epilepsies and 25 percent of epilepsies with onset in the first year of life. There are approximately 2,000 to 4,000 new cases in the United States each year. The long-term overall prognosis for patients with infantile spasms is poor. Cognitive and developmental delay is severe in 70 percent of patients, often with psychiatric problems such as autistic features or hyperactivity. It has been found that 50-70 percent of patients develop other seizure types and that 18 to 50 percent will develop LGS or some other form of symptomatic generalized epilepsy. (Original Source)
