NA · Changhai Hospital · NCT06346093

This study is testing if giving patients with advanced gastric cancer special capsules made from healthy gut bacteria, along with their regular cancer treatments, can help them feel better and improve their chances of recovery.

What this trial studies

This study evaluates the efficacy and safety of fecal microbiota transplantation (FMT) capsules in combination with chemotherapy and anti-PD-L1 therapy for patients with advanced gastric cancer. It is a randomized, double-blind, placebo-controlled trial, meaning participants will be assigned to either receive the FMT capsules or a placebo without knowing which they are receiving. The study aims to determine if FMT can enhance treatment outcomes in patients with locally advanced, unresectable, or metastatic gastric adenocarcinoma. Participants must provide tumor tissue and have measurable disease to qualify.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with confirmed advanced gastric adenocarcinoma who can provide tumor tissue and have a good performance status.

Not a fit: Patients with contraindications to fecal microbiota transplantation or those currently receiving systemic antibiotics may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for patients with advanced gastric cancer.

How similar studies have performed: While fecal microbiota transplantation has shown promise in other conditions, its application in advanced gastric cancer is relatively novel and untested.
