C. difficile infection keeps us apart.

New research brings us closer together.

Now Enrolling at MNGI Digestive Health in Plymouth, Minnesota: The CDI-SCOPE study for adults with recurrent C. difficile infection (CDI).

If you are eligible and decide to participate:

  • There is no placebo
  • Study sponsor covers costs of the study drug and participation
  • You will receive the study drug by colonoscopy
CDI SCOPE Clinical Trial

This clinical study tests an FDA-approved study drug when given by colonoscopy

CDI-SCOPE is a clinical study that investigates RBX2660 to find out if it can prevent recurrence of your CDI when administered through a colonoscopy.

The study drug, RBX2660, is approved by the US Food and Drug Administration (FDA), and marketed in the United States as REBYOTA™ (fecal microbiota, live – jslm)1 for rectal administration only.

Study doctors want to find out if RBX2660 is also effective in preventing CDI recurrence when given by colonoscopy.

CDI-SCOPE Clostridioides difficile trial

There is no placebo and you may be compensated for your time and travel

Study patients receive expert medical care and specialized attention from the study team. There is no placebo drug given and you do not have to pay for the study drug, supplies, procedures, or tests that are part of the study.

Your participation will help us understand more about RBX2660 in people with recurrent CDI.

If you or someone you know has a C. difficile infection, contact Allison Jentges at MNGI Digestive Health to learn more.

Frequently Asked Questions

What is a clinical study?

In a clinical study like this one, participants receive a study drug to find out if it is effective, and whether or not it has side effects.

What is a study drug?

A study drug is a substance that is being tested in clinical studies. The study is reviewed by an ethics committee that approves testing the study drug in people.

Why is this study important?

Individuals with recurrent CDI can suffer from repeated episodes of severe diarrhea and other difficult symptoms that not only interrupt day-to-day activities but can create a serious burden on life. Many people with this condition are successfully treated with antibiotics, but these can cause even more disruption to the gut. Unfortunately, this disruption can sometimes lead to additional CDI episodes when the antibiotics are stopped.

This study is evaluating a United States Food and Drug Administration (FDA) approved study drug called RBX2660 (REBYOTA) to find out how it works when administered through a colonoscopy. Pharmaceutical companies use clinical studies like this one to learn more about study drugs before and after they are made available to the public. Study participants can help us in this important research.

Why should I take part in this study?

Participation in a clinical trial is voluntary. Clinical studies are important for medical advances. Current treatments for diseases have only become available because individuals agreed to participate in clinical studies.

Thank you for considering participation in this study.
