During each study visit, investigators/assessors evaluated acne severity of the participants' faces using the ISGA scale: 0=clear skin with no lesions (L); 1=almost clear, rare non-inflammatory L; 2=mild, some non-inflammatory L with no more than a few inflammatory L, no nodular L; 3=moderate, many non-inflammatory L, may have some inflammatory L, but no more than 1 small nodular L; 4=severe, many non-inflammatory and inflammatory L, but no more than a few nodular L; 5=very severe, many non-inflammatory and inflammatory L, and more than a few nodular L.

Intent-to-Treat (ITT) Population: all participants who were randomized to and received at least 1 application of study product. Participants with missing Week 12 evaluations were considered failures. Failures are defined as those participants with a 1-grade improvement, no improvement, or a worsening.

During each study visit, trained study personnel at every investigational center assessed the inflammatory (pustules [small inflamed elevation of the skin that is filled with pus], papules [solid elevation of skin with no visible fluid], nodules [larger than papules with significant depth]) lesion counts for each participant. Each type of lesion was counted separately, and counts were taken from the face (including forehead, nose, cheeks, and chin). Missing values were imputed using the last observation carried forward (LOCF) method.

ITT Population. Participants who missed >=16 days of treatment or reported lost medication and never began treatment were excluded from the analysis. In the LOCF method, the last available observation, including BL, was used to estimate subsequent missing data points.

During each study visit, trained study personnel at every investigational center assessed the non-inflammatory (open comedones [blackheads] and closed comedones [whiteheads]) lesion counts for each participant. Each type of lesion was counted separately, and counts were taken from the face (including forehead, nose, cheeks, and chin).

ITT Population. Participants who missed >=16 days of treatment or who reported they had lost their medication and never began treatment were excluded from the analysis. Missing values for all other participants were imputed using the LOCF method.

During each study visit, trained study personnel at every investigational center assessed the inflammatory (pustules, papules, nodules) and non-inflammatory (open and closed comedones) lesion counts for each participant. Each type of lesion was counted separately; the lesion counts were taken from the face (including forehead, nose, cheeks, and chin). Total lesion counts were calculated as the sum of the inflammatory and non-inflammatory lesion counts.

ITT Population. Participants who missed >=16 days of treatment or who reported they had lost their medication and never began treatment were excluded from the analysis. Missing values for all other participants were imputed using the LOCF method.

During each study visit, trained study personnel at every investigational center assessed the inflammatory (pustules, papules, nodules) and non-inflammatory (open and closed comedones) lesion counts for each participant. Each type of lesion was counted separately; the lesion counts were taken from the face (including forehead, nose, cheeks, and chin). Total lesion counts were calculated as the sum of the inflammatory and non-inflammatory lesion counts. Percent change from Baseline to Week 12 was calculated as the value at Week 12 minus the value at Baseline divided by the Baseline value * 100.

ITT Population. Participants who missed >=16 days of treatment or who reported they had lost their medication and never began treatment were excluded from the analysis. Missing values for all other participants were imputed using the LOCF method.

During each study visit, participants evaluated their facial acne (excluding the scalp) using the SGA scale: 0=free of acne, with only an occasional blackhead/whitehead; 1=several blackheads/whiteheads and small pimples, no tender deep-seated bumps/cysts; 2=several to many blackheads/whiteheads and small to medium-sized pimples, one deep-seated bump/cyst; 3=many blackheads/whiteheads, many medium- to large-sized pimples, few deep-seated bumps/cysts; 4=presence of blackheads/whiteheads, several to many medium- to large-sized pimples, deep-seated bumps/cysts dominate.

ITT Population. Participants with missing Week 12 evaluations were considered failures. Failures were defined as those participants with an SGA score >=2.

Systolic and diastolic blood pressure were measured at Baseline and Week 12 (end of study). Mean change from Baseline was calculated as the mean value at Week 12 minus the mean value at Baseline.

ITT Population. Only those participants with data available at both Baseline and Week 12 were analyzed.

Temperature was measured at Baseline and Week 12 (end of study). Mean change from Baseline was calculated as the mean value at Week 12 minus the mean value at Baseline.

ITT Population. Only those participants with data available at both Baseline and Week 12 were analyzed.

Pulse rate was measured at Baseline and Week 12 (end of study). Mean change from Baseline was calculated as the mean value at Week 12 minus the mean value at Baseline.

ITT Population. Only those participants with data available at both Baseline and Week 12 were analyzed.

Erythema (Er, redness), dryness (Dr), and peeling (Pn), were evaluated independently by the investigator as: 0 (absent)=no Er, Dr, or Pn; 1 (slight)=faint red/pink coloration (col.), barely perceptible Dr with no flakes or fissure, mild localized Pn; 2 (mild)=light red/pink col., perceptible Dr with no flakes/fissure, mild and diffuse Pn; 3 (moderate)=medium red col., easily noted Dr and flakes but no fissure; 4 (severe)=beet red col., Dr with flakes and fissure, prominent dense Pn. Change from Baseline was calculated as the value at Weeks 2, 4, 8, and 12 minus the the value at Baseline.

ITT Population. Only those participants with data available at both Baseline and the indicated assessment week were analyzed.

Itching and burning/stinging (piercing pain) were evaluated independently by the investigator as: 0 (none)=normal, no discomfort; 1 (slight)=noticeable discomfort that caused intermittent awareness; 2 (moderate)=noticeable discomfort that caused intermittent awareness and interfered occasionally with normal daily activities; 3 (strong)=definite continuous discomfort that interfered with normal daily activities. Change from Baseline was calculated as the value at Weeks 2, 4, 8, and 12 minus the value at Baseline.

ITT Population. Only those participants with data available at both Baseline and the indicated assessment week were analyzed.

Mean duration of study product use was calculated as the average total duration inclusive of missed applications of the study product.

ITT Population

An AE included, but was not limited to, any clinically significant worsening of a pre-existing condition; an event occurring from overdose (i.e., a dose higher than that indicated in the protocol) of the study product, whether accidental or intentional; an event occurring from abuse (e.g., use for nonstudy reasons) of the study product; or an event that was associated with the discontinuation of the use of the study product.
