“Gastroesophageal adenocarcinoma represents one of the most frequent tumor types worldwide and, tragically, a leading cause of cancer-related deaths. Compared to what has historically been reported for OS with the current approved standard of care1, the OS findings from the combination of zanidatamab and chemotherapy in this trial are very compelling,” said Dr. Elena Elimova, lead trial investigator and a medical oncologist at Princess Margaret Cancer Centre. “HER2 has been recognized as a predictive biomarker for these cancers, and it is promising to see a treatment targeting this expression exhibit strong and durable anti-tumor activity when administered with chemotherapy.”
