Outcome Measures
Primary Outcomes (1)
Percentage of Patients With Clostridium Difficile Infection at 4- Weeks of Follow-up.
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.
Day 1 to the 4 week Follow-up Visit.

Eligibility Criteria
You may qualify if:
- Expected minimum hospital stay of 5 days
- Expected ≥5 day course of intravenous (IV) ceftriaxone alone or in combination with a macrolide
- Clinical diagnosis of moderate to severe lower respiratory tract infection consisting of signs and symptoms of a lower respiratory tract infection and Pneumonia Severity Index (PSI/PORT) score for CAP of 90-130, inclusive. Evidence of a new or progressive infiltrate on chest x-ray is recommended.
You may not qualify if:
- Presence of a diarrheal illness within 72 hours prior to randomization
- Current treatment for CDAD or ongoing active CDI, as evidenced by clinical signs of diarrhea along with the presence of toxin A and/or B (or their respective genes, tcdA and/or tcdB) of C. difficile in the stool
- Number of previous CDAD episodes \>1 within 12 weeks of randomization and no C. difficile infection (CDI) within 4 weeks of randomization
- Use of antibiotics within 1 month of start of study drug except for the current illness.
