Dr. Geoffrey Guy, GW's Chairman stated, "As Epidiolex® nears its final stages of clinical development and as GW prepares for future U.S. launch, the time is right to start building our in-house U.S. commercial infrastructure. Julian's deep experience at building and running a major U.S. pharmaceutical business built on specialty products will be complemented by the relocation of Justin to the U.S. with his intimate knowledge of GW, its products and pipeline. Together, they will spearhead GW's growth in the U.S. and help to bring much needed new treatments to patients."

"I am very excited about building a meaningful commercial presence in the U.S. for GW. As exemplified by Epidiolex, a potentially important new treatment in the field of pediatric epilepsy, GW's products, if approved, offer the prospect of making a meaningful difference to patients' lives," said Mr. Gangolli. "I wish to bring my experience of building a successful business for Allergan to GW and look forward to working with Justin and the entire GW team to optimise the Company's prospects in this key market."

GW will locate its U.S. operation in Southern California where Mr Gangolli and Mr Gover will be based.  GW is also continuing to expand its UK manufacturing and R&D operations in preparation for future commercialization as well as pipeline development.
