Clinical trial for HER2-positive Gastric Cancer
Official title A Phase Ⅲ Study of Rilvegostomig in Combination With Fluoropyrimidine and Trastuzumab Deruxtecan as the First-line Treatment for HER2-positive Gastric Cancer
ClinicalTrials.gov ID: NCT06764875
What this study is testing
What is Rilvegostomig (AZD2936)?
An investigational intravenous drug being studied for HER2‑positive gastric or gastro‑esophageal junction cancer.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study compares how well the new drug plus standard therapy works and how safe it is, versus a different standard treatment, in patients whose tumors show a certain marker (PD‑L1 CPS ≥ 1).
- Who it's for
- Adults with HER2‑positive, locally advanced or metastatic stomach or gastro‑esophageal junction cancer that has a PD‑L1 CPS of 1 or higher.
- What's involved
- Participants will receive either the new drug with standard chemotherapy and a drug called T‑DXd, or a different standard treatment that includes trastuzumab, chemotherapy, and pembrolizumab. They will have regular clinic visits, blood tests, imaging scans, and other safety checks.
- Time commitment
- The study lasts about 12–18 months, with visits every few weeks for treatment and monitoring, plus periodic imaging to track progress.
- Phase 3: a large, late-stage study
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
