Pembrolizumab plus gut microbiome changes after pancreatic chemo
This Phase 2 study tests whether changing the gut microbiome (the gut’s helpful bacteria) and giving pembrolizumab after chemotherapy can improve outcomes for people with operable pancreatic cancer. It aims to see if this approach can boost the immune system after standard treatment and help reduce cancer returning.

Common questions
- Are there clinical trials studying Metronidazole?
- Yes. Clin2 currently lists 31 recruiting studies that include Metronidazole, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Metronidazole trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Metronidazole an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Metronidazole or a specific trial is right for you.
