Summary
Brief summary (as posted)
Trastuzumab deruxtecan's (T-DXd's) efficacy and safety has been confirmed in traditional clinical trials, there is a lack of real-world evidence, especially among Chinese patients. The objective of this study is to evaluate real-world effectiveness and safety profile of T-DXd by collecting real-world data treating in patients with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma.

Participants must meet all the following inclusion criteria to be eligible for the study: 1. Participants with pathologically diagnosed locally advanced unresectable or metastatic gastric cancer/gastroesophageal junction adenocarcinoma (GC/GEJA). 2. ≥18 years of age at the time of starting the first dose of T-DXd and signing informed consent form (ICF), capable of providing informed consent. 3. HER2-positive status (IHC 3+ or IHC 2+/ISH +). 4. Received prior anti-cancer treatment regimens according to National Medical Products Administration indication or clinical judgement of physician. 5. Decision to newly initiate T-DXd before study ICF signing. If the participants have started the first dose of T-DXd no longer than 21 days before enrollment, they could be enrolled if the signed and dated ICF could be obtained. Exclusion Criteria: Participants who meet any of the following criteria will be excluded from the study: 1. Pregnancy or breastfeeding. 2. Participants who at the time of data collection of the study are participating in or have participated in an interventional study that remains blinded. 3.
