GW Pharmaceuticals presents latest cannabidiol oral solution (CBD) data at the 13th European Congress of Epileptology

VIENNA, Austria, Aug. 28, 2018 (GLOBE NEWSWIRE) -- GW Pharmaceuticals plc (NASDAQ: GWPH, GW, the Company or the Group), a world leader in the development and commercialization of cannabinoid prescription medicines, presents a variety of data on cannabidiol oral solution (CBD) at the 13th Annual European Congress of Epileptology (ECE), taking place in Vienna, Austria from 26-30 August 2018.

The studies provide additional insight into the safety and efficacy of GW’s CBD oral solution in the treatment of seizures associated with Lennox-Gastaut syndrome (LGS) and Dravet syndrome, two rare and severe forms of childhood-onset epilepsy that are highly treatment-resistant1 ,2 . In addition, data related to the pharmacology of CBD, and its antiseizure properties, will provide additional understanding of CBD’s role in the management of such diseases. A marketing authorization application for GW’s CBD oral solution is currently under review by the European Medicines Agency (EMA).

“GW is proud to be presenting a wealth of data on its CBD oral solution to the epilepsy community. Our comprehensive pre-clinical and clinical programs provide an understanding of the way in which CBD exhibits anti-seizure effects and further supports its efficacy and tolerability profile in patients living with two of the most difficult-to-treat forms of epilepsy,” stated Justin Gover, GW’s Chief Executive Officer. “There is still a huge unmet medical need for effective medicines that help people suffering from severe forms of treatment resistant epilepsy, and we believe that our CBD oral solution may present an important new therapeutic option in the future.”

CBD data highlights:
Highlights include the presentation of pooled efficacy and safety data from two phase III randomized placebo-controlled trials of CBD in LGS, Phase 1 drug-drug interaction data on the co-administration of CBD and clobazam, and the potential role of GPR55 and the TRPV1 receptor-dependent interaction in the anti-epileptic properties of CBD.
