Primary Outcome Measures:
  • Percent Change From Cycle 6 to Baseline in the Total Lesion Count (Open and Closed Comedones, Papules, Pustules, and Nodules) in the FAS (Full Analysis Set) [ Time Frame: Cycle 6 (Day 15±3 days of Treatment Cycle 6) and Baseline ] [ Designated as safety issue: No ]
    Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)*100, so that improvement is indicated by a larger percent change.

  • Percent Change From Cycle 6 to Baseline in the Total Lesion Count (Open and Closed Comedones, Papules, Pustules, and Nodules) in the PPS (Per Protocol Set) [ Time Frame: Cycle 6 (Day 15±3 days of Treatment Cycle 6) and Baseline ] [ Designated as safety issue: No ]
    Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)*100, so that improvement is indicated by a larger percent change.

    Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (lesion count at Baseline - lesion count at Cycle 6)/(lesion count at Baseline)*100, so that improvement is indicated by a larger percent change.
