Using fecal microbial transplants to treat pancreatic cancer

Pilot Study Using Fecal Microbial Transplants in Patients With Pancreatic Cancer

Early Phase 1 Interventional M.D. Anderson Cancer Center · NCT04975217

This study is testing whether fecal microbial transplants can help patients with pancreatic cancer who are going to have surgery by looking at how safe and effective the treatment is.

What this trial studies

This early phase I trial investigates the safety and effects of fecal microbial transplants (FMT) in patients with resectable pancreatic ductal adenocarcinoma (PDAC) scheduled for surgery. The study aims to assess the tolerability and feasibility of FMT, as well as its impact on the gut, oral, and tumor microbiomes. Patients will receive FMT during a colonoscopy and take FMT capsules weekly for four weeks, followed by standard surgical resection of tumors. Participants will be monitored for changes in their microbiomes and immunological responses after the treatment.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with pancreatic ductal adenocarcinoma who are expected to undergo surgical resection.

Not a fit: Patients with advanced pancreatic cancer not eligible for surgery or those with significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for patients with pancreatic cancer by enhancing their immune response and potentially controlling disease progression.

How similar studies have performed: While fecal microbial transplants have shown promise in other conditions, this specific application for pancreatic cancer is novel and has not been extensively tested.
