Summary
This study will evaluate efficacy and safety information about RBX2660 for the treatment of recurrent Clostridium difficile infection (CDI), and will compare the efficacy of one treatment with RBX2660 versus antibiotic-treated historical controls. Enrolled subjects will receive one treatment consisting of two doses of RBX2660 (microbiota suspension).

- Documented history that the subject's recurrent CDI is controlled while on antibiotics even if the subject is not currently on antibiotics.
- A positive stool test for the presence of C. difficile within 60 days prior to enrollment
