A Study of JYP0066 Cream in Mild-to-Moderate Atopic Dermatitis

This is a Phase 2 research study testing an investigational topical cream called JYP0066 for the treatment of mild-to-moderate atopic dermatitis (eczema) in teenagers (12-17 years old) and adults. The study will check whether JYP0066 cream can reduce eczema signs and symptoms such as redness, itching, dryness, and skin thickening, and whether it is safe and well tolerated. Participants will be randomly assigned to one of four groups: they will apply either 4%, 3%, or 2% JYP0066 cream, or a matching placebo cream, to eczema-affected skin twice a day for 8 weeks. All creams will look the same. This helps the study compare which concentration works best and how safe each one is.
