结局指标
主要结局
Absolute Change From Baseline in Facial Total Lesion Counts to Week 12
时间窗: From Baseline to Week 12
Total lesion counts corresponded to the sum of inflammatory and non-inflammatory lesions, and papules. The investigator (or subinvestigator) counted all inflammatory lesions (papules, pustules, and nodular lesions) and non-inflammatory lesions (open and closed comedos; diagnosis based on palpation) on the face.
次要结局
- Absolute Change From Baseline in Facial Inflammatory Lesions (IL) Counts to Week 12(From Baseline to Week 12)
- Absolute Change From Baseline in Facial Non Inflammatory Lesions (NIL) Counts to Week 12(From Baseline to Week 12)
- Percentage of Participants Who Achieved an IGA Score of 1 (Almost Clear) or 0 (Clear) and At Least a 2-Grade Improvement From Baseline to Week 12(From Baseline to Week 12)
