Study Overview

Brief Summary

This study aims to evaluate whether the combination of Akkermansia muciniphila with infliximab can improve intestinal mucosal healing in patients with Crohn's disease compared with infliximab alone.

Detailed Description

This is a prospective, randomized, controlled clinical study designed to evaluate the efficacy of Akkermansia muciniphila combined with infliximab in patients with Crohn's disease.

Eligible patients will be randomly assigned to receive either intravenous infliximab at standard clinical doses combined with Akkermansia muciniphila supplementation administered once daily or intravenous infliximab alone. The primary endpoint is complete mucosal healing at Week 26, and the secondary endpoint include endoscopic remission, endoscopic response, clinical remission and clinical response at Week 26.
