Lyophilized Fecal Transplant vs Lyophilized Fecal Filtrate in Recurrent C Diff Infection

Phase 2
Completed
Conditions
Recurrent Clostridium Difficile Infection
Enterocolitis
Interventions
Biological: LSFF
Biological: LFMT
Registration Number
NCT03353506
Lead Sponsor
Dina Kao
Brief Summary

Fecal microbiota transplantation (FMT) for the treatment of recurrent Clostridium difficile infection (RCDI) has traditionally been offered as fecal slurry administered by enema, nasogastric tube or endoscopy. Frozen oral capsules have also shown efficacy. The potential advantage of lyophilized FMT is the relative ease of manufacturing and storage compared with fecal slurry.

Sterile fecal filtrate has previously been shown to prevent Clostridium difficile infection (CDI) recurrence, suggesting that live bacteria may not be needed. This study will compare lyophilized sterile fecal filtrate (LSFF) with lyophilized FMT (LFMT) in the treatment of recurrent Clostridium difficile infection (RCDI).

Detailed Description

This prospective double blind randomized pilot study will enroll 40 subjects with recurrent Clostridium difficile infection in a 1:1 ratio to receive either LSFF or LFMT by capsules.

Subjects will receive 15 capsules at week 0 and be assessed at Weeks 1, 4, 12 and 24. If treatment fails, subjects will be given open label LFMT from the same donor. If treatment fails again, another FMT will be offered and the form and route of FMT delivery will be at the discretion of the treating physician.
