Overview
This is a Phase 2b randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of three active dose regimens of MORF-057 in adult patients with moderately to severely active Ulcerative Colitis (UC).
Description
This is a Phase 2b randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of three active dose regimens of MORF-057 plus a placebo regimen in study participants with moderately to severely active UC. After completion of the 12-week Induction Period, participants may be switched to a different active MORF-057 regimen during the Maintenance Period. Those randomized into the placebo group in the Induction Period will be switched to receive an active MORF-057 regimen during the Maintenance Period.
