A Phase 2 Study to Evaluate MORF-057 in Adults With Moderately to Severely Active Crohn's Disease

This is a Phase 2, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy and safety of induction therapy with 3 active dose regimens of MORF-057 versus matching placebo in adult study participants with moderately to severely active CD. After completion of the 14-week Induction Period, all participants will receive open-label MORF-057 during the 38-week Maintenance Period. All participants who complete the full 52-week Treatment Period will also have the opportunity to continue treatment in a 52-week Long-Term Extension.
