- Percentage of Patients With Clostridium Difficile Infection at 4- Weeks of Follow-up. [ Time Frame: Day 1 to the 4 week Follow-up Visit. ]Percentage of subjects with CDI, based on the protocol definition of CDI (defined as 3 or more unformed stools per 24 hour period and a stool sample being positive for C. difficile toxin A and/or B [or their respective genes, tcdA and/or tcdB], based on the clinical site local laboratory results) from Day 1 to the 4-week Follow-up Visit in the SYN-004 treatment group compared to the placebo group, imputing early termination without CDI as not being treatment failures.
