"GW has very substantial clinical activity under way. In the next two months, we will commence all four pivotal trials of Epidiolex in Dravet syndrome and Lennox-Gastaut syndrome and we expect initial top line data from at least one of these trials by the end of the year," stated Justin Gover, GW's Chief Executive Officer. "In addition, the expanded access program continues to point to

the potential for Epidiolex to treat additional forms of epilepsy and we expect to commence clinical development programs in further potential target indications during 2015. A further release of data from this expanded access program is expected to be presented during the second quarter. Beyond epilepsy, we are continuing to progress further clinical trials in a number of

additional cannabinoid product candidates during the remainder of this year. With so much activity and a robust balance sheet, we are pleased with progress and confident in our prospects."
