Vertex shares climb after Sionna trial failure
Shares of drugmaker Vertex Pharmaceuticals VRTX.O climbed 7.65% to $534 premarket after Sionna Therapeutics SION.O said it would discontinue development of its SION-719 experimental cystic fibrosis drug after it failed to meet the main goal in a mid-stage trial.
