Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

GEMINI-PeriOp GC study will assess the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity of novel agents or novel combinations as perioperative treatment in participants with locally advanced resectable gastric, gastroesophageal junction (GEJ), or esophageal adenocarcinoma who have not received previous treatment for the disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This Phase II, open-label, multi-drug, multi-center platform study consists of individual sub-studies, each allows the assessment of multiple novel agents or novel combinations.

Participants will be assigned across 3 sub-studies, to have sufficient evaluable participants of the confirmed recommended dose by Safety Review Committee (SRC) for study intervention in each corresponding sub-study.
