Percent Change in Inflammatory Acne Lesion Counts From Baseline to Week 12

Percent change in inflammatory lesion counts from Baseline to Week 12. It is calculated by taking the Week 12 count minus the Baseline count and then dividing by the Baseline count. Thus, a negative percent change will reflect a reduction in lesion counts.

Number of Participants With Improvement in Investigator Global Assessment by at Least One Grade From Baseline to Week 12

The Investigator Global Assessment used a static categorical scale, with zero corresponding to no acne and higher scores reflecting more severe acne: 0 No acne lesions. Rare non-inflammatory lesions. Some non-inflammatory lesions, no more than a few inflammatory lesions. No nodulo-cystic lesions. Many non-inflammatory lesions, some inflammatory lesions, no more than one nodulo-cystic lesion. Many noninflammatory and inflammatory lesions but no more than a few nodulo-cystic lesions. Highly inflammatory lesions, multiple nodulo-cystic lesions.
