Overview
Brief Summary
This is a Phase 2, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy and safety of 3 active dose regimens of MORF-057 in adult study participants with moderately to severely active Crohn's disease (CD).
Detailed Description
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.

Outcomes
Primary Outcomes
Proportion of participants with endoscopic response at Week 14 as determined using the Simple Endoscopic Score-CD (SES-CD)
Time Frame: Baseline to Week 14
The SES-CD is an endoscopic scoring system for evaluating CD activity. Endoscopic response is defined as an SES-CD decrease from baseline of ≥50%
Secondary Outcomes
- Proportion of participants with clinical response at Week 14 as determined using the Crohn's Disease Activity Index (CDAI)(Baseline to Week 14)
- Proportion of participants with clinical remission at Week 14 as determined using the CDAI.(Baseline to Week 14)
