What this Trial Is About

This research aims to evaluate the safety and effectiveness of duvakitug injection in people with moderately to severely active Crohns Disease. It is a multicenter, randomized, double-blind, placebo-controlled Phase 3 study focused on maintaining treatment benefits. The study includes participants aged 16 to 80 years and is sponsored by Sanofi. Participants receive subcutaneous injections of duvakitug or placebo according to the study protocol. The trial includes a 40-week pivotal maintenance sub-study followed by a 240-week open-label extension sub-study for those who continue. The total treatment duration may be up to 280 weeks, with up to 43 on-site visits throughout the study. During the study, participants will have regular assessments including clinical remission, endoscopic response, and other measures related to Crohns Disease activity. Safety is monitored by tracking adverse events and antidrug antibody levels. There is a 45-day follow-up visit after treatment ends. The study duration may be up to 286 weeks depending on participation in the extension phase.
