What this trial studies

This observational study aims to gather real-world data on patients with advanced gastric cancer who have started treatment with trastuzumab-deruxtecan (Enhertu) since September 2022. It will collect clinical data from patients currently undergoing treatment, those who have experienced disease progression, and those who have passed away or are in hospice care. The study will evaluate efficacy through metrics such as overall survival, progression-free survival, and tumor response rate, with data collection continuing until March 2027 for consenting patients.

Who should consider this trial

Good fit: Ideal candidates include patients aged 19 years or older with HER2-positive metastatic, recurrent, or unresectable gastric/gastroesophageal adenocarcinoma who have received trastuzumab-deruxtecan as a third-line or later treatment.

Not a fit: Patients with HER2-negative gastric cancer or those who have not consented to participate will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the real-world effectiveness and safety of trastuzumab-deruxtecan for patients with advanced gastric cancer.

How similar studies have performed: Other studies have shown success with real-world data collection for cancer treatments, indicating that this approach is promising and not entirely novel.
