NCT02332356

Brief Summary

This randomized, controlled study aims to evaluate the impact of therapeutic intervention (step up) for the patients who are clinical remission with Magnetic Resonance Enterocolonography (MREC) active. In addition, to evaluate the impact of therapeutic step down for the patients who archived clinical and MREC remission. The primary endpoint is the rate of clinical remission at 104 weeks.
