A Study to Evaluate Efficacy and Safety of MK-7240 in Participants With Moderately to Severely Active Ulcerative Colitis (MK-7240-001)
Study Details
Study Description
Brief Summary
The purpose of this protocol is to evaluate the efficacy and safety of MK-7240 in participants with moderately to severely active ulcerative colitis. Study 1's primary hypotheses are that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12, and that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at week 52. Study 2's primary hypothesis is that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12.
