Shares of Jazz Pharmaceuticals (JAZZ.O) surged by 20.49% today, reaching a new 52-week high of $170.11. This significant price movement follows the announcement of positive results from the Phase 3 HERIZON-GEA-01 trial, which demonstrated that Ziihera, in combination with chemotherapy, significantly improved progression-free survival and overall survival for patients with HER2-positive gastroesophageal adenocarcinoma. The stock's breakout above previous resistance levels signals strong bullish momentum, reflecting investor confidence in the drug's potential as a new standard of care. Looking ahead, Jazz plans to submit a supplemental Biologics License Application to the FDA in 2026, further bolstering its market position.
