Study summary

Approximately 520 patients will be entered into this study taking place throughout Australia and Europe. This study aims to determine if an investigational drug is safe and effective for treating symptoms of C. difficile-associated diarrhea (CDAD) and lowering the risk of repeat episodes of CDAD. The investigational drug will be evaluated in comparison to current standard antibiotic treatment, so all patients will receive active medication. All study related care is provided including doctor visits, physical exams, laboratory tests, and study medication. The total length of participation is approximately 6 weeks.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 19, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
