ClinicalTrials.gov Identifier:
NCT02240108
First received: September 11, 2014
Last updated: April 26, 2017
Last verified: April 2017
  Purpose
The primary objective is to determine the efficacy of rifaximin DR tablets vs. placebo for the induction of clinical remission and endoscopic response following 16 weeks of treatment in subjects presenting with active moderate Crohn's disease. A key secondary objective is to evaluate clinical and endoscopic remission following an additional 36 weeks of treatment.

Condition Intervention Phase
Crohn's Disease Drug: Rifaximin DR Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter, Multiregional, One Year Study to Assess the Efficacy and Safety of Twice Daily Oral Rifaximin Delayed Release Tablets for Induction of Clinical Remission With Endoscopic Response at 16 Weeks Followed by Clinical and Endoscopic Remission at 52 Weeks in Subjects With Active Moderate Crohn's Disease

Primary Outcome Measures:
  • Clinical symptom remission [ Time Frame: Week 16 ]
    First of the co-primary efficacy measures: Change from baseline in (1) number of liquid/very soft stools AND (2) abdominal pain rating.

  • Endoscopic response [ Time Frame: Week 16 to Week 17 ]
    Second of the co-primary efficacy measures: Change from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD).


Secondary Outcome Measures:
  • Clinical symptom remission [ Time Frame: Week 52 ]
    First of the key co-secondary efficacy measures: Change from baseline in (1) number of liquid/very soft stools AND (2) abdominal pain rating at Week 52.

  • Endoscopic remission [ Time Frame: Week 52 ]
    Second of the key co-secondary efficacy measures: Change from baseline in SES-CD at Week 52.

Detailed Description:

RECD3126 is a double-blind, placebo-controlled, parallel-group, multicenter, multiregional, 52-week study to assess the efficacy and safety of rifaximin DR tablets for the induction of clinical remission and endoscopic response at 16 weeks followed by clinical and endoscopic remission after 52 weeks of continuous therapy in subjects with active moderate Crohn's disease.

Subjects will be randomized in a 1:1 allocation to rifaximin or placebo at the beginning of the treatment period and will maintain treatment assignment throughout the duration of the study. Ileocolonoscopy will be performed on all subjects at baseline, between Weeks 16 and 17 (end of the Induction Phase), and following completion of the 36-week Long Term Treatment Phase (Week 52).
