Researchers are investigating the efficacy and safety of duvakitug in people with moderately to severely active Crohns Disease in a multinational, multicenter, randomized, double-blind, placebo-controlled Phase 3 study. The trial includes three sub-studies aiming to evaluate duvakitugs effects compared to placebo during induction treatment phases, focusing on clinical remission and endoscopic response at 12 weeks. Participants receive subcutaneous injections of duvakitug or placebo following the study protocol. The study duration can be up to 35 weeks, including a screening period of up to 5 weeks, followed by a 12-week induction phase in either Sub-Study 1 open-label, Sub-Study 2 pivotal induction, or Sub-Study 3 extended induction for non-responders. A 6-week follow-up period applies to participants not entering the maintenance study. Throughout the trial, participants undergo scheduled visits for assessments including clinical remission based on Crohns Disease Activity Index and endoscopic scores. Safety is monitored with reports of adverse events and serum drug levels. Up to 8 to 15 visits are planned depending on the sub-study, with follow-up continuing for 45 days after the last dose for those not moving to maintenance treatment.
