Study Endpoints

Primary Endpoints

Mean Percent Reduction from Baseline in Non-Nodular Inflamed Lesion Count
84 days

Per Protocol Population (PPP) was assessed for the mean percent reduction compared to baseline in non-nodular lesion count (papules and pustules) at Day 84. If a patient was withdrawn from the study prior to Day 84 for lack of efficacy, then their data was carried forward for this analysis.

Mean Percent Reduction from Baseline in Non-Inflamed Lesion Count
84 days

Per Protocol Population (PPP) was assessed for the mean percent reduction in non-inflamed lesion count (open and closed comedones) compared with baseline at Day 84. If a patient was withdrawn from the study prior to Day 84 for lack of efficacy, then their data was carried forward for this analysis.

Safety Analysis
84 Days

All 601 patients randomized and dispensed study drug were included in the safety analysis. The frequency, severity, and relationship to the study drug for adverse events in each treatment group were used to compare the safety of the study medications.
