ASCO 2026 | Prof. Xiaotian Zhang and Prof. Yelena Janjigian: The DESTINY-Gastric Program Reshapes HER2-Targeted Therapy in Gastric Cancer as Chinese and U.S. Experts Discuss the Next Chapter
The landmark results of the DESTINY-Gastric04 (DG04) trial have firmly established trastuzumab deruxtecan (T-DXd) as the missing piece in second-line HER2-targeted treatment for gastric cancer. At the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, the DESTINY-Gastric03 (DG03) study was also unveiled, highlighting the promising potential of T-DXd in the first-line setting. As T-DXd moves from later-line therapy toward frontline treatment for HER2-positive gastric cancer, an increasing number of patients stand to benefit.
