Study start date: November 26, 2019
Actual date on which the first participant was enrolled.This study will find out if trastuzumab deruxtecan is safe and works for participants with gastric or gastroesophageal junction cancer. They must have human epidermal growth factor receptor 2 (HER2)-positive gastric or gastro-esophageal junction (GEJ) cancer: * that cannot be removed surgically * that has moved to other parts of the body * that got worse during or after treatment that included trastuzumab The study will enroll about 80 participants. Sites will be in North America and the European Union.
