Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Absolute Change in Facial Inflammatory Lesion Counts at Week 12 | Facial area lesion counts were made at the forehead, left and right cheeks, nose, and chin at baseline and at each treatment period visit. Inflammatory lesion counts were based on the following definitions: papule: a solid, elevated lesion < 0.5 centimeter (cm) in diameter (by inspection) with surrounding erythematous halo; pustule: an elevated lesion containing pus < 0.5 cm in diameter (by inspection) with surrounding erythematous halo; nodule: palpable solid erythematous lesion > 0.5 cm in diameter (by inspection); has depth, not necessarily elevated. A negative change from Baseline indicates that the number of inflammatory lesions decreased. Analyses were based on Analysis of Covariance (ANCOVA) model for the endpoint with treatment group and pooled study center as factors and baseline value as a covariate. | Baseline (Day 1) to Week 12 | 
| Percentage of Participants With Investigator Global Assement (IGA) Success at Week 12 | The investigator assessed the participant's inflammatory lesions on the face using the IGA 5-point scale. The scale ranges from 0 (best): clear, no evidence of papules or pustules to 4 (worst): severe, inflammatory lesions are more apparent, many papules/pustules, there may or may not be a few nodulocytic lesions. Success was defined as at least a 2-point decrease (improvement) from Baseline on the IGA assessment as well as a score of clear (0) or almost clear (1). The percentage of participants who achieved success is reported. | Baseline (Day 1) to Week 12 |
