Study Summary

This is a prospective, multicenter, randomized, double-blinded, placebo-controlled Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe Clostridioides difficile infection (CDI) resulting in hospitalization within the last year may be eligible for the study. Subjects who are deemed failures following the blinded treatment per the pre-specified treatment failure definition may elect to receive an unblinded dose of RBX2660.

Primary Outcome

The primary efficacy endpoint was the absence of CDI diarrhea for 8 weeks after study treatment. The model-estimated rate of treatment success, that is the model-estimated percentage of participants that met the primary efficacy endpoint, was estimated using a Bayesian hierarchical model, which formally incorporated data from a previous randomized Phase 2B study (NCT02299570) of RBX2660.

Interventions

  • DRUG Placebo
  • DRUG RBX2660
  • DRUG Open label RBX2660 (only for confirmed CDI recurrence)
