Summary
This Phase 3 trial tests an oral drug called ICP-488 in 383 adults with moderate to severe plaque psoriasis. Participants are randomly assigned to receive either the drug or a placebo for 16 weeks. The main goal is to see if the drug can significantly clear or nearly clear the skin, as measured by doctor assessments and symptom scores.
