Eligibility Criteria

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of participants who achieve an intertriginous PGA (iPGA) score of clear (0) or almost clear (1) with a ≥ 2-grade improvement | Intertriginous Physician Global Assessment (iPGA) is a clinical tool for assessing the current state/severity of a subject's psoriasis in the intertriginous areas at a given timepoint. It is a static 5-point assessment of plaque qualities on the clinical characteristics of erythema, scaling, and plaque thickness/elevation within the intertriginous areas. The iPGA ranges from 0 to 4, and is calculated as Clear (0), Almost Clear (1), Mild (2), Moderate (3), and Severe (4). Higher iPGA scores represent more severe disease. | from Baseline to Week 12 |
