Официальное название

A Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Assess the Efficacy, Safety, and Tolerability of SAR444336 in Participants With Microscopic Colitis in Clinical Remission With Budesonide

Обзор

This is a parallel, placebo-controlled, multicenter, randomized, double-blind, Phase 2, proof of concept study. The study aims to evaluate the efficacy and safety of SAR444336 in adult participants with microscopic colitis. Participants are required to have a histologically confirmed diagnosis of microscopic colitis, be in clinical remission and be receiving budesonide therapy. The overall study duration is approximately 32 weeks.
