Study Objectives

0 Primary · 7 Secondary · Reporting Duration: At baseline versus within 6 days after 3rd cycle of IRCD and 3 months after 3rd cycle. 1 cycle of IRCD lasts 5 days and is administered once a month, followed by regular diet for the rest of the month.

Month 3
Effect of IRCD on patient quality of life: Short Inflammatory Bowel Disease questionnaire (SIBDQ)
Month 3
Number of Participants with Clinical remission as per CDAI
Number of Participants with Clinical response as per CDAI (100 points)
Number of Participants with Clinical response as per CDAI (70 points)
Day 6
Effect of IRCD on endoscopic outcomes
Number of Participants with Clinical remission as per Patient Reported Outcome (PRO) score
Patient global assessment
Day 6
Changes in clinical markers of disease activity
Month 3
Changes in gut metabolites (including short-chain fatty acid and bile acid profiles) and microbiome profiles (using 16S rRNA/shotgun metagenomics)
Day 6
Changes in cytokines/chemokines and immune cell profiles
Day 6
Change in C-reactive protein (CRP) at baseline versus after 3rd cycle of IRCD (or control at corresponding time point) in both IRCD and control group.
Change in Erythrocyte Sedimentation Rate (ESR) at baseline versus after 3rd cycle of IRCD (or control at corresponding time point) in both IRCD and control group.
Change in fecal calprotectin at baseline versus after 3rd cycle of IRCD (or control at corresponding time point) in both IRCD and control group.
