PRIMARY outcome
Timeframe: Baseline through Week 12Population: The ITT population consisted of all randomized participants who were dispensed study drug. MCMC was used to impute missing values. Here, 'Overall Number of Participants Analyzed' (N) signifies number of participants evaluable for this outcome measure.
Percentage of participants in each treatment group achieving an acne severity IGA score of "clear (score=0)" or "almost clear (score=1)" and achieving an acne severity IGA score of at least 2 grades less than Baseline.

PRIMARY outcome
Timeframe: Baseline, Week 12Population: The ITT population consisted of all randomized participants who were dispensed study drug. Multiple imputation (MCMC) was used to impute missing values.
Inflammatory lesions were characterized by papules, pustules, nodules, and cysts. Least squares means and standard deviations from an analysis of covariance (ANCOVA) with factors of treatment group and analysis center and the respective Baseline lesion count as a covariate. Negative least squares means values represent decrease from Baseline.

Percent of participants in each treatment group achieving at least a 4 point reduction on Item 1 (Pimple) of the patient- reported evaluation of facial acne compared to Baseline. The Pre-Face is a 7-item questionnaire that assesses acne vulgaris-related signs, symptoms, and impacts. Item 1 of the questionnaire was to assess the pimples on the participant's face at their worst in the 24 hours prior to administration on an 11-point numeric rating scale (NRS) ranging from 0 ("no pimples at all") to 10 ("pimples as bad as you can imagine").

The Pre-Face is a 7-item questionnaire that assesses acne vulgaris-related signs, symptoms, and impacts. Item 5 of the questionnaire was to assess how embarrassed the participant felt because of the acne at their worst, in the 24 hours prior to administration on an 11-point NRS ranging from 0 ("not embarrassed at all") to 10 ("extremely embarrassed").
