What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Percentage of Participants With Treatment Success at Week 8	Treatment success was defined as at least a 2-grade improvement from Baseline in IGA score and an IGA score equating to "Clear" or "Almost Clear". IGA was based on a 5-point scale ranging from 0 to 4; where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe.	8 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Treatment Success at Weeks 12, 6, 4, and 2	Treatment success was defined as at least a 2-grade improvement from Baseline in IGA score and an IGA score equating to "Clear" or "Almost Clear". IGA was based on a 5-point scale ranging from 0 to 4; where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe.	12 weeks
