Thanks for posting. I figured that was the reason we are up.
I am mixed on a (possible) takeover. I've only been a shareholder a short time so can't complain about a quick profit but I like several of their compounds and the not-so-distant royalty revenue could be fairly significant.
If they were to be taken over my guess would be some company looking to acquire them for their oncology program/potential or perhaps AstraZeneca is so high on 118 that they don't want to pay the royalty :-).
