Intervention MeSH terms: Vancomycin; Ciprofloxacin; Neomycin; Fluconazole; Polyethylene glycol 3350
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Parallel Assignment

Healthy volunteers: No

Summary:

      The purpose of this study is to determine the effect of a novel gut microbiota-targeted
      therapeutic regimen (bowel lavage and antibiotics with or without an antifungal) in the
      management of active Crohn's Disease (CD) or indeterminate colitis (IBDU) that is refractory
      to conventional, immunosuppressive therapy. In addition, the study will determine the effect
      of PEG lavage alone on fecal calprotectin and gut microbiota in patients who are undergoing a
      PEG lavage for clinical care.
