Cantor Fitzgerald analyst Elemer Piros believes GW Pharmaceuticals shares could recover quickly from the selloff on the negative results with GWP42006 in adult patients with focal seizures. The analyst highlights the announcement of an advisory committee hearing for Epidiolex on April 18. The "clear near-term focus" is the successful commercialization of Epidiolex for pediatric pharmacoresistant seizures upon potential approval in the second half of 2018, Piros tells investors in a research note. He keeps an Overweight rating on GW shares with a $192 price target.
