This substantial price movement, representing a $20.01 increase, was accompanied by unusually heavy trading volume, indicating strong investor response to the clinical breakthrough and pushing the stock well above its prior 52-week range of $5.00 - $16.00.

The reported Phase 1/2 trial results demonstrated compelling efficacy, with bezuclastinib achieving a mean total symptom score reduction of 24.3 points, significantly outperforming the placebo's 15.4 points (adjusted difference 8.91; p = 0.0002).
