My guess is the expected trial enrollment completion next month. The announcement can come any day now.
The completion of trial enrollment is a big deal since it gives us a definite timeline on when the NDA can be submitted and a lot of investors/speculators are looking for the right time to jump in.
People say 3rd time's the charm. I think so too.
Still, I don't expect the stock price to jump too high until after the financing is settled.
