ECOSPOR IV: An Open-Label Study Evaluating SER-109 in Recurrent Clostridioides Difficile Infection

Summary

Cohort 1: Subjects who had a Clostridioides difficile infection (CDI) recurrence in study SERES-012 within 8 weeks of receipt of study drug will be eligible. The purpose of this cohort is to assess safety and efficacy of SER-109 in reducing recurrence of CDI in adults who had a CDI recurrence within 8 weeks after receipt of SER-109 or Placebo in study SERES-012. Cohort 2: Cohort 2 is an open-label program for subjects who were not part of SERES-012. The purpose of this cohort is to describe safety and tolerability of SER-109 in subjects 18 years of age or older with at least a first recurrence of CDI.
