Fidaxomicin vs Vancomycin for C. diff Infection
What You Need to Know Before You Apply
What is the purpose of this trial?
This is a randomized, double-blind study to assess the safety and efficacy of fidaxomicin compared to vancomycin for decolonization of C. difficile in IBD patients. A total of 60 patients who meet eligibility criteria will be randomized 1:1 to either the fidaxomicin or vancomycin arm. The vancomycin arm will receive a dose of 125 mg PO q 6 hours for 10 days. The fidaxomicin arm will receive 200 mg PO BID for 10 days. In order to ensure blinding, both antibiotics will be concealed in opaque 00 capsule shells. In addition, those in the fidaxomicin arm will receive 2 placebo capsules so that all participants will receive 4 capsules daily for 10 days. Microbiome assessment and C. difficile testing will be performed at baseline, day 5, day 10, and weeks 4, 8, and 26.
Will I have to stop taking my current medications?
The trial protocol does not specify whether you need to stop taking your current medications. However, if you are on chronic antibiotics, you may not be eligible to participate.
Is fidaxomicin safe for treating C. diff infections?
How does the drug fidaxomicin differ from vancomycin in treating C. diff infection?
Fidaxomicin is unique because it specifically targets C. diff bacteria with minimal impact on normal gut bacteria, leading to fewer recurrences of infection compared to vancomycin. It is also taken less frequently, twice a day, and is poorly absorbed into the bloodstream, which reduces systemic side effects.23467
