Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Absolute Change From Baseline to Week 12 in Total Lesion Counts.
Time Frame: Baseline (Day 1) and Week 12
|
The investigator (or subinvestigator) counted all inflammatory lesions (papules, pustules, and nodular lesions) and non-inflammatory lesions (open and closed comedones) on the face at each study visit.
An open comedone was an open, widely dilated follicle with black-colored sebum, due to melanin and oxidation, and keratinous material that forms a plug, thereby obstructing the pilosebaceous duct.
A closed comedone was a closed follicle filled with impacted sebum covered by keratin that has a whitish color.
A papule was a small, raised, red, dome-shaped palpable lesion.
A pustule was a raised, dome-shaped palpable lesion containing yellow fluid (pus).
A nodule might be a raised or deep-seated, dome-shaped palpable lesion of at least 5 millimeters in diameter.
Day 1 was Baseline and change from baseline was calculated by subtracting the Baseline value from post-randomization value at Week 12.
