Title: A 52-Week, Phase 3, Randomized, Active Comparator and Placebo-Controlled, Parallel Design Study to Evaluate the Efficacy and Safety/Tolerability of Subcutaneous Tildrakizumab (SCH 900222/MK-3222), Followed by an Optional Long-Term Safety Extension Study, in Subjects With Moderate-to-Severe Chronic Plaque Psoriasis (Protocol No. MK-3222-011)
Brief Summary: This study is being conducted to evaluate the efficacy and safety/tolerability of tildrakizumab (SCH 900222/MK-3222) in a population of participants with moderate-to-severe plaque psoriasis.
