2Treatment groups
Experimental Treatment
Placebo Group
Group I: SAR444727 5% BID per lesionExperimental Treatment1 Intervention
During the double-blinded period, 2 target lesions per participant (with difference no greater than 1 point in total sign scores \[TSS\]) were randomized in 1:1 ratio to receive either SAR44727 Gel 5 percent (%) or matching placebo (i.e., each participant was treated with both SAR444727 5% BID and placebo in parallel). During open-label period, participants applied SAR444727 Gel, 5% twice daily (BID) to the all atopic dermatitis (AD)-affected areas, except the scalp, palms, soles and genitals through Days 15 to 42.
Group II: Placebo then SAR444727 5% BID per lesionPlacebo Group2 Interventions
Multiple topical doses of placebo for 14 days, and PRN473 (SAR444727) for 28 days
