Clinical Trial Summary

The primary purpose of this study is to examine the efficacy and safety of E6011 at 12 weeks after administration by means of double-blind placebo-controlled trial.

Description:

Participants with moderate to severe Crohn's disease will be enrolled in this study.

The study will include screening period, remission-induction period (double-blind), rescue period (open-label), extension period (open-label), post-observation period, and a follow-up period.

At the end of remission-induction period, participants with reduction in Crohn's disease activity index (CDAI) score of 70 points or more when compared to baseline will move on to the open-label extension period, and participants with less than 70 points reduction in CDAI score will move on to the rescue period. At the end of the rescue period, participants with a reduction in the CDAI of 70 points or more will move on to the open-label extension period and with less than 70 points reduction in the CDAI score will be discontinued.

The post-observation period will include in-person assessment after the completion or discontinuation of the extension period, and participants will be contacted by telephone, etc. after the last dose of study drug administration. Participants will be contacted over phone after the last dose of study drug administration for follow up assessments.

CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, haematocrit, and body weight. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.	Week 12
