What this trial studies

This Phase II trial evaluates the efficacy and safety of cadonilimab combined with chemotherapy, with or without AK117, in patients with resectable gastric or gastroesophageal junction adenocarcinoma. Participants must have a confirmed diagnosis and meet specific health criteria, including an ECOG performance status of 0 or 1. The study aims to determine the effectiveness of this combination treatment as a neoadjuvant therapy before surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with a confirmed diagnosis of resectable gastric or gastroesophageal junction adenocarcinoma and an ECOG performance status of 0 or 1.

Not a fit: Patients with unresectable disease or those with active autoimmune diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with resectable gastric or gastroesophageal junction adenocarcinoma.

How similar studies have performed: While this approach is being explored in this trial, similar combination therapies have shown promise in other studies, indicating potential for success.
