KERX—I am purely speculating from timing of the PR (today) and how the market typically interprets such news release. If indeed positive, they would have said so in today's PR with further details to be shared on the CC.

I see this PR from KERX as a very bullish sign, it´s almost as if they copied directly from Acadia..
