Outcome
Met primary endpoint
paper 198 (91·7%) of 216 patients in the per-protocol population given fidaxomicin achieved clinical cure, compared with 213 (90·6%) of 235 given vancomycin, meeting the criterion for non-inferiority (one-sided 97·5% CI -4·3%). PMID 22321770 ↗
paper Non-inferiority was also shown for clinical cure in the mITT population PMID 22321770 ↗
