- Inflammatory Lesion Counts [ Time Frame: Baseline to Week 12 ]Absolute change from Baseline to Week 12 in mean inflammatory lesion counts
- Non-inflammatory Lesion Counts [ Time Frame: Baseline to Week 12 ]Absolute change from Baseline to Week 12 in mean non-inflammatory lesion counts
- Percentage of Participants With Success on the Evaluator's Global Severity Score [ Time Frame: Baseline to Week 12 ]Success was defined as at least a two grade reduction and clear or almost clear at Week 12. The Evaluator's Global Severity Score has grades for acne severity of 0 (Clear), 1 (Almost Clear), 2 (Mild), 3 (Moderate), and 4 (Severe), with higher scores indicating worse severity.
- Inflammatory Lesion Count Changes at Week 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, 8 ]Absolute change from Baseline to Week 2, 4, and 8 in mean inflammatory lesion counts
- Non-inflammatory Lesion Count Changes at Week 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, 8 ]Absolute change from Baseline to Week 2, 4, and 8 in mean non-inflammatory lesion counts
- Inflammatory Lesion Count Percentage Changes at Week 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, 8 ]Percentage change from Baseline to Week 2, 4, and 8 in mean inflammatory lesion counts
- Non-inflammatory Lesion Count Percentage Changes at Week 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, 8 ]Percentage change from Baseline to Week 2, 4, and 8 in mean non-inflammatory lesion counts
- Percentage of Participants With Success on the Evaluator's Global Severity Score at Weeks 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, and 8 ]Success was defined as at least a two grade reduction and clear or almost clear at the visit. The Evaluator's Global Severity Score has grades for acne severity of 0 (Clear), 1 (Almost Clear), 2 (Mild), 3 (Moderate), and 4 (Severe), with higher scores indicating worse severity.
- Percentage of Participants With Two Grade Success on the Evaluator's Global Severity Score - at Weeks 2, 4, and 8 [ Time Frame: Baseline to Week 2, 4, and 8 ]Two grade success was defined as at least a two grade reduction. The Evaluator's Global Severity Score has grades for acne severity of 0 (Clear), 1 (Almost Clear), 2 (Mild), 3 (Moderate), and 4 (Severe), with higher scores indicating worse severity.
