Study summary

The goal is to evaluate the benefit of adding bezlotoxumab to repeat fecal microbiota transplantation (FMT) in patients with recurrent Clostridioides difficile infections after failure of FMT alone.

Read the detailed description

Initial failure of FMT in breaking the cycle of recurrent C. difficile infections is associated with a greater risk of subsequent failure. Previous analysis showed that FMT failure is associated with delayed repair of fecal microbiota at one week after administration. The hypothesis underlying this trial is that increased symptom-free interval by administration of bezlotoxumab can improve the outcomes of a second FMT.
