October 31, 2018 updated by: Synthetic Biologics Inc.

A Double-Blind, Placebo-Controlled, Multicenter Study of SYN-004 Compared to Placebo for the Prevention of C.Diff in Patients With a Diagnosis of a Lower Respiratory Tract Infection

A Phase 2b Parallel-Group, Double-Blind, Placebo-Controlled, Multicenter Study of SYN-004 Compared to Placebo for the Prevention of Clostridium difficile Infection (CDI) in Hospitalized Patients receiving IV ceftriaxone with a Diagnosis of a Lower Respiratory Tract Infection (LRTI).

Detailed Description

This is a Phase 2b, randomized, double-blind, placebo controlled, parallel-group, multi-center proof-of-concept study to assess the potential of SYN-004 in the prevention of CDI and the unwanted side effects of IV antibiotic treatment in at risk patients who are hospitalized for LRTI and receiving IV ceftriaxone alone or in combination with a macrolide. Subjects will be 50 years or older. The entire duration of the study may be up to 59 days. All patients will be evaluated for the occurrence of CDI and AAD by testing according to local diagnostic standards and monitoring for diarrhea (3 or more unformed stools per 24 hour period).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Day 1 to the 4 week Follow-up Visit.
