Bacillus Velezensis DSM 33864 for Reduction of the Risk of Recurrent Clostridioides Difficile Infections

The goal of this multi-center randomized double-blinded placebo-controlled trial is to evaluate the tolerability and effect of a probiotic dietary supplement on the reduction of the risk of recurrent C. difficile infection in adults who have experienced two previous C. difficile infection episodes. The main aim of this study is to assess the effect of a probiotic dietary supplement on the colonization (cell counts) of C. difficile over time and also to assess the correlation between level of C. difficile colonization and recurrence of CDI. Approximately, 104 research subjects will be randomized into two arms and will use either one capsule daily of the probiotic supplement or placebo once daily with breakfast, for 8 weeks. All outcomes will be compared across the supplementation and placebo arm.
