Primary Endpoints
Segment 2A: Clinical Cure (CC) of Clostridioides Difficile Infection (CDI) Per Protocol (PP)/Modified Intent-to-Treat (mITT) Population
12 days

Percentage of patients with CC at the test of cure (TOC) visit on day 12. CC was defined as survival and the resolution of diarrhea in the 24-hour period immediately before end of treatment (EOT--day 10) that was maintained for 48 hours post EOT without a requirement for additional CDI treatment. Diarrhea was defined as 3 or more unformed bowel movements (UBMs) in a 24-hour period; fewer than 3 UBMs was considered as resolution of diarrhea. A UBM was defined as a Type 5, 6, or 7 bowel movement on the Bristol Stool Chart.
