We are now accepting volunteers for the following Clinical Research Studies:
C-Diff 1st Diagnosis or 1st Recurrence Treatment Study
Have you been diagnosed with C. difficile diarrhea? You may qualify if you are 18 years of age or older and have a first or second episode of C-diff infection (CDI.)
Study participants will be provided study medications, laboratory analyses, and follow up visits with our providers at no cost. A small stipend and help with transportation to and from the clinical research site may also be available.
C. Diff Treatment For Adults with Recurrent Infections
In a recent study, participants with recurrent C. diff who received CP101 after completing a round of antibiotics were significantly less likely to experience another episode of C. diff, compared to participants who received antibiotics alone. In the study, 74.5% of participants who received CP101 achieved a clinical cure, meaning they did not experience a recurrence of C. diff within 8 weeks of taking CP101.
CP101 is a microbiome therapy. The microbiome is the community of organisms that live in the intestinal tract.
