This study is looking at two different antibiotics, fidaxomicin and vancomycin, to see which is better at getting rid of *C. difficile* (a type of bacteria that can cause severe diarrhea) in people with Inflammatory Bowel Disease (IBD). You might be able to join if you are over 18, have an IBD diagnosis, and are scheduled for an outpatient colonoscopy. We want to see if these medicines are safe and effective at clearing *C. difficile* over 8 weeks. This study is currently recruiting 60 participants.

Study design

This is a randomized, double-blind study involving 60 participants. You would be randomly assigned to receive either fidaxomicin or vancomycin, and neither you nor the study team would know which medicine you are receiving.

What's involved

You would take medication for 10 days. Monitoring will continue through week 8, with some follow-up extending to week 26, including stool samples and recording symptoms.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for safety and effectiveness for 8 weeks after treatment ends, with some assessments continuing up to 26 weeks.
