Piper Jaffray analyst Danielle Brill lowered her price target for GW Pharmaceuticals to $160 from $210 saying the ceiling for Epidiolex may be lower than originally projected due to patient discontinuations. However, she does "not think we're close to hitting a plateau" following GW's Q3 results. In the midterm, the analyst expects the ongoing European launch, additional off-label usage and label expansion into the tuberous sclerosis complex to serve as primary drivers of growth. Brill, who lowered her peak sales estimate for Epidiolex to $1.5B from $2.0B, believes the 12% post-earnings selloff in shares of GW Pharmaceuticals is overdone. Continued growth over the coming quarters should "restore confidence and drive shares higher," she says. The analyst keeps an Overweight rating on the stock.
