Outcome Measures
Primary Outcomes (4)
Number of Participants With Improvement of at Least 2 Grades in the Investigator's Static Global Assessment (ISGA) Score From Baseline to Week 12
During each study visit, investigators/assessors evaluated acne severity of the participants' faces using the ISGA scale: 0=clear skin with no lesions (L); 1=almost clear, rare non-inflammatory L; 2=mild, some non-inflammatory L with no more than a few inflammatory L, no nodular L; 3=moderate, many non-inflammatory L, may have some inflammatory L, but no more than 1 small nodular L; 4=severe, many non-inflammatory and inflammatory L, but no more than a few nodular L; 5=very severe, many non-inflammatory and inflammatory L, and more than a few nodular L.
Baseline (Day 1) and Week 12
Mean Change From Baseline (BL) to Week 12 in Inflammatory Lesion Counts
During each study visit, trained study personnel at every investigational center assessed the inflammatory (pustules \[small inflamed elevation of the skin that is filled with pus\], papules \[solid elevation of skin with no visible fluid\], nodules \[larger than papules with significant depth\]) lesion counts for each participant. Each type of lesion was counted separately, and counts were taken from the face (including forehead, nose, cheeks, and chin). Missing values were imputed using the last observation carried forward (LOCF) method.
Baseline (Day 1) and Week 12
Mean Change From Baseline to Week 12 in Non-inflammatory Lesion Counts
During each study visit, trained study personnel at every investigational center assessed the non-inflammatory (open comedones \[blackheads\] and closed comedones \[whiteheads\]) lesion counts for each participant. Each type of lesion was counted separately, and counts were taken from the face (including forehead, nose, cheeks, and chin).
Baseline (Day 1) and Week 12
Mean Change From Baseline to Week 12 in Total Lesion Counts
During each study visit, trained study personnel at every investigational center assessed the inflammatory (pustules, papules, nodules) and non-inflammatory (open and closed comedones) lesion counts for each participant. Each type of lesion was counted separately; the lesion counts were taken from the face (including forehead, nose, cheeks, and chin). Total lesion counts were calculated as the sum of the inflammatory and non-inflammatory lesion counts.
Baseline (Day 1) and Week 12
Secondary Outcomes (10)
Mean Percent Change From Baseline to Week 12 in Lesion Counts (Total, Inflammatory, and Non-inflammatory)
