GW Pharmaceuticals Announces Epidiolex(R) Receives Fast Track Designation From FDA for the Treatment of Dravet Syndrome

LONDON, June 6, 2014 (GLOBE NEWSWIRE) -- GW Pharmaceuticals plc (Nasdaq: GWPH) (AIM:GWP) ("GW," "the Company" or "the Group"), a biopharmaceutical company focused on discovering, developing and commercializing novel therapeutics from its proprietary cannabinoid product platform, today announced that the United States Food and Drug Administration (FDA) has granted Fast Track designation to GW's investigational cannabidiol (CBD) product, Epidiolex®, in the treatment of Dravet syndrome, a rare and catastrophic treatment-resistant form of childhood epilepsy.

FDA's Fast Track program facilitates the development and review of drugs intended to treat serious conditions and fill an unmet medical need. A drug development program with Fast Track designation is afforded greater access to the FDA for the purpose of expediting the drug's development, review and potential approval to get important new drugs to the patient earlier.

"GW is focused on advancing the Epidiolex development program as rapidly as possible with the aim of addressing the significant unmet need in children suffering from Dravet syndrome. The granting of Fast Track designation, in addition to Epidiolex having already received orphan drug designation from the FDA, represents significant additional support toward this objective," stated Justin Gover, GW's Chief Executive Officer. "With GW having already opened an Investigational New Drug (IND) for Epidiolex, we are on track to commence a Phase 2/3 clinical trial in Dravet syndrome in the second half of this year."

In addition to Dravet syndrome, GW plans to conduct a clinical development program for Epidiolex in the treatment of Lennox-Gastaut syndrome (LGS). Following receipt earlier in 2014 of orphan drug designation by the FDA in LGS, GW expects to hold a pre-IND meeting with the FDA for Epidiolex in the treatment of LGS in mid-2014, and expects to conduct two Phase 3 trials in LGS during 2015.

About Dravet syndrome

Dravet syndrome, also known as Severe Myoclonic Epilepsy of Infancy (SMEI), is a rare and catastrophic form of epilepsy for which there is currently no cure. Seizures begin in the first year of life in an otherwise typically developing infant. Initial seizures are most often prolonged events (status epilepticus) and, in the second year of life, other seizure types emerge. All seizure types are remarkably resistant to medical therapy and the prognosis for Dravet syndrome is poor. Individuals with Dravet syndrome face a higher incidence of SUDEP (sudden unexplained death in epilepsy) and have associated co-morbid conditions, which also need to be properly managed. Children with Dravet syndrome do not outgrow this condition and it affects every aspect of their daily lives.
