Clostridium Difficile Infection clinical trials at UC Health
5 research studies open to eligible people

  • A Clinical Study of Experimental RBX2660 to Restore Healthy Gut Bacteria in People With Recurrent Clostridium Difficile Infection

    “This study involves an investigational new drug called RBX2660 (microbiota suspension), that may prevent your recurrent CDI.”

    open to eligible people ages 18 years and up

    This is a prospective, multicenter, randomized, double-blinded, placebo-controlled Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization within the last year may be eligible for the study. Subjects who are deemed failures following the blinded treatment per the pre-specified treatment failure definition may elect to receive an unblinded RBX2660 enema.

  • Bezlotoxumab (MK-6072) Versus Placebo in Children With Clostridium Difficile Infection (CDI) (MK-6072-001)

    open to eligible people ages 1-17

    The primary objectives of this study are to evaluate the pharmacokinetics (PK), safety, and tolerability of bezlotoxumab in children aged 1 to <18 years of age with a confirmed diagnosis of Clostridium difficile infection (CDI) who are receiving antibacterial drug treatment. The primary hypothesis is that the area under the concentration-time curve from 0 to infinity (AUC0-inf) of bezlotoxumab after treatment of pediatric participants with bezlotoxumab is similar when compared to the AUC0-inf of bezlotoxumab after treatment of adults with bezlotoxumab,

  • Clostridium Difficile VaccineTrial

    “Spending a lot of time at the doctor? Learn about a study of an investigational vaccine for people who may be at risk of C. Diff. Infection.”

    open to eligible people ages 50 years and up

    The Clover trial is evaluating an investigational vaccine that may help to prevent Clostridium difficile infection. Participants in the study are adults 50 years of age and older, who are at risk of developing Clostridium difficile infection. The study will assess whether the vaccine prevents the disease, and whether it is safe and well tolerated. Each subject will receive 3 doses of Clostridium difficile vaccine or placebo and be followed for up to 3 years after vaccination for potential Clostridium difficile infection.

  • Experimental "SER-109" for the Treatment of Adults With Recurrent Clostridium Difficile Infection (bacteria in the colon)

    “Have you had Clostridium difficile infection (CDI) at least three times in the past 9 months?”

    open to eligible people ages 18 years and up

    Subjects will receive an oral dose of SER-109 in 4 capsules once daily for 3 consecutive days in Treatment Group I or matching placebo once daily for 3 consecutive days in Treatment Group II. The purpose of this study is to demonstrate the superiority of SER-109 vs placebo to reduce recurrence of CDI in adults up to 8 weeks after initiation of treatment.

  • Fecal Microbiota Transplant National Registry

    open to all eligible people

    A national data registry of patients receiving fecal microbiota transplantation (FMT) or other gut-related-microbiota products designed to prospectively assess short and long-term safety and effectiveness
