Treatment Success of Group A (2 Doses of RBX2660) vs Group B (2 Doses of Placebo) (ITT)
Lasso di tempo: 8 weeks after last assigned study treatment
|
The primary endpoint is to evaluate treatment success, defined as the absence of CDAD without the need for retreatment with C. difficile anti-infective therapy or fecal transplant (FT) at 56 days after administration of the last assigned study enema, of Group A (two enemas of RBX2660) vs. Group B (two enemas of placebo).

SF-36 Scores Obtained at the 1-week, 4-week, and 8-week Assessments Visits During the Double-blind Period as Compared to Baseline (ITT)
Lasso di tempo: 8-week
|
The validated SF-36 scale was used to identify changes to quality of life (QoL) following study treatment.
Each component is analyzed on a norm-based scoring (0-100) with a higher score representing an improvement in QoL.

Time to CDAD Recurrence After Completion of the Assigned Study Treatment for Group A vs. Group B (ITT)
Lasso di tempo: 8-weeks
