    RAPP is up 22.4% pre-market after reporting a positive Phase 2 bipolar-mania trial for RAP-219 that met its primary endpoint. The statistically significant efficacy result, favorable tolerability, and stated path toward Phase 3 provide a concrete clinical catalyst for the move.

    WHYA 22.4% move is substantial, but it is proportionate to positive Phase 2 proof-of-concept data with a met primary endpoint and Phase 3 plans.
