Population / Age or Age Range / % Women / Ethnicity / Inclusion Criteria | Population: Adults with acute symptoms of CDI and a positive result on a stool toxin test Mean age: 62 % women: 56 Inclusion criteria: 16 years of age or older with a diagnosis of CDI, defined by the presence of diarrhea (a change in bowel habits, with >3 unformed bowel movements in the 24-hour period before randomization) and C. difficile toxin A, B, or both in a stool specimen obtained within 48 hours before randomization. | ||
Sample Size (N) / Intervention(s) / Control (s) / Study Duration | N=629 Intervention 1: Fidaxomicin 200 mg 2 times/day (n=302) Intervention 2: Vancomycin 125 mg 4 times/day (n=327) Treatment duration: 10 days Followup period: 30 days | ||
Outcomes Evaluated | a. Clinical cure, defined by the resolution of diarrhea (i.e., three or fewer unformed stools for 2 consecutive days), with maintenance of resolution for the duration of therapy and no further requirement (in the investigator’s opinion) for therapy for CDI as of the second day after the end of the course of therapy. b. Clinical recurrence, defined by the reappearance of more than three diarrheal stools per 24-hour period within 4 weeks after the cessation of therapy; C. difficile toxin A or B, or both, in stool; and a need for retreatment for CDI c. Median time to resolution of diarrhea d. All-cause mortality e. Adverse events | ||
