Zanidatamab Shows Breakthrough Efficacy in HER2-Positive Cancer
- Clinical Trial Results: Jazz Pharmaceuticals announced that the HERIZON-GEA-01 Phase 3 trial results show that the combination of Zanidatamab with chemotherapy yields a median progression-free survival (PFS) of 12.4 months, significantly higher than the 8.1 months seen with traditional trastuzumab plus chemotherapy, indicating its potential in treating HER2-positive gastroesophageal adenocarcinoma.
