Fidaxomicin Versus Vancomycin for the Treatment of Clostridium Difficile-Associated Diarrhea (CDAD)
This is a comparative study to investigate the safety and efficacy of fidaxomicin versus vancomycin in subjects with Clostridium difficile-Associated Diarrhea (CDAD).
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
- Cure Rate at End of Therapy [ Time Frame: Study day 10 (+/- 2 days) ] [ Designated as safety issue: No ]Percentage of participants with 3 or fewer unformed stools for 2 consecutive days and maintained through the end of therapy, and the subject no longer needed specific anti-Clostridium antibacterial treatment after completion of the course of study medication.
- Recurrence [ Time Frame: Study days 11-40 ] [ Designated as safety issue: No ]Percentage of participants with the re-establishment of diarrhea to an extent(based on frequency of passed unformed stools) that was greater than that noted on the last day of study medication, and the demonstration of either toxin A or B or both of C. difficile, and retreatment with CDI anti-infective therapy was needed.
