Recent Updates on JAZZ stock
Jazz Pharmaceuticals has seen significant positive developments recently, primarily driven by the favorable results from the HERIZON-GEA-01 study, which evaluated the bispecific HER2-directed antibody zanidatamab in HER2+ advanced/metastatic gastroesophageal adenocarcinoma. This has led multiple analysts to adjust their price targets upwards. Piper Sandler raised its target due to a reduced risk adjustment in sales estimates, while UBS, despite a downgrade to Neutral, acknowledged the improved outlook but noted that the recent stock surge reflects the oncology momentum. Truist and BofA also increased their targets, citing the promising potential of Ziihera, a drug with significant market prospects in HER2+ cancers. Baird’s adjustment was based on the study’s results being a best-case scenario, further supporting the stock’s upward trajectory.
