This was an efficacy variable. An expert grader evaluated each side of the face (included forehead, cheeks and chin), the left and the right side, for IL (presence of papules and pustules), NIL (presence of open and closed comedones) and the TLs. The mouth, nose, periocular area, nasogenian, and superior and inferior eyelids were excluded. The evaluator was also blinded. BL was defined as Day 1. The percent change was calculated as the value at Wk 8 minus the value at BL.

The Intent to treat (ITT) analysis set included data from all randomized participants who received the study drug. The number of participants available at that particular time point were used for analysis.

This was an efficacy variable. An expert grader (blinded) evaluated the left and the right side of the face extending from the hairline to the mandible (included forehead, cheeks and chin). The evaluator assessed the IL by counting the number of papules and pustules. The mouth, nose, periocular area, nasogenian, and superior and inferior eyelids were excluded. BL was defined as Day 1. The percent change was calculated as the percent value (count of IL) at each individual visit (percent value at wk 1, 2 and 4) minus the value at BL respectively.

ITT used. Only those participants available at the specified time points were analyzed (re presented by n=x, x in the category titles).

This was an efficacy variable. An expert grader (blinded) evaluated the left and the right side of the face extending from the hairline to the mandible (included forehead, cheeks and chin). The evaluator assessed the NIL by the presence of open and closed comedones. The mouth, nose, periocular area, nasogenian, and superior and inferior eyelids were excluded. BL was defined as Day 1. The percent change was calculated as the percent value (count of NIL) at each individual visit (percent value at Wk 1, 2 and 4) minus the value at BL respectively.

ITT population. Only those participants available at the specified time points were analyzed (represented by n=X, X in the category titles).

This was an efficacy variable. An expert grader (blinded) evaluated the left and the right side of the face extending from the hairline to the mandible (included forehead, cheeks and chin). The evaluator assessed the total lesions by the sum of both inflammatory and non-inflammatory lesions on each side (left side and right side). The mouth, nose, periocular area, nasogenian, and superior and inferior eyelids were excluded. BL was defined as Day 1. The percent change was calculated as the percent value (count of total lesions) at each individual visit (percent value at Wks 1, 2 and 4) minus the value at baseline respectively.

ITT population. Only those participants available at the specified time points we re analyze d (represented by n=X, X in the category titles).

The evaluator (blinded) evaluated the acne severity of the participants' face using the ISGA scale ranging from 0 to 5. The grading was 0= Clear, skin with no IL or NILs; 1= Almost clear, rare NILs with no more than one small IL ; 2= Mild, some NILs with no more than few ILs (papules/pustules only, no nodular lesions); 3= Moderate Upto many NILs and may have some ILs but no more than one small nodular lesion ; 4= Severe, Upto many NILs and ILs but no more than a few nodular lesions; 5= Very severe, many NILS and ILs more than a few nodular lesions, may have cystic lesions. Thus higher score indicated severity of the disease. BL was defined as Day 1. The mean change was calculated as value at each visit (Wks 1,2,4 and 8) minus the value at BL respectively.

ITT population. Only those participants available at the specified time points we re analyze d (represented by n=x, x in the category titles).

This was a tolerability variable. The expert grader (blinded evaluator) assessed each left and right side of the face individually at each study visit. The areas on the face excluding nose, nasogenian, and superior and inferior eyelids were evaluated. The evaluator conducting the assessment for the participant remained blinded for the treatment assigned. Erythema is condition characterized by redness or rash on the skin. The assessment of the erythema was graded on 0 to 5 scale based on severity by the evaluator. 0=None, 1=Very minimal, 2=mild, 3= moderate, 4=severe, and 5= Very severe. Thus higher score indicated severity of the disease. BL was defined as Day 1. The mean change was calculated as value at each individual visit (wk 1,2,4 and 8) minus the value at BL respectively. The change from BL was '0' for Wk 4 and Wk 8, and hence statistical analysis was not done.

ITT population. Only those participants available at the specified time points we re analyze d (represented by n=X, X in the category titles).

This was a tolerability variable. The expert grader (blinded evaluator) assessed each left and right side of the face individually at each study visit. The areas on the face excluding nose, nasogenian, and superior and inferior eyelids were evaluated. The evaluator conducting the assessment for the participant remained blinded for the treatment assigned. The assessment of the dryness was graded on 0 to 5 scale based on severity by the evaluator. 0=None, 1=Very minimal, 2=mild, 3= moderate, 4=severe, and 5= Very severe. Thus higher score indicated more severity. BL was defined as Day 1. The mean change was calculated as value at each individual visit (Wk 1,2,4 and 8) minus the value at baseline respectively. The change from BL was '0' for Wk 2, Wk 4, and Wk 8 and hence statistical analysis was not done.

The areas on the face excluding nose, nasogenian, and superior and inferior eyelids were evaluated. The evaluator conducting the assessment for the participant remained blinded for the treatment assigned. The assessment of the peeling was graded on 0 to 5 scale based on severity by the evaluator. 0=None, 1=Very minimal, 2=mild, 3= moderate, 4=severe, and 5= Very severe. Thus higher score indicated more severity. BL was defined as Day 1. The mean change was calculated as value at each individual visit (Wk 1,2,4 and 8) minus the value at BL respectively. The change from BL was '0' for Wk (1, 4 and 8) and hence statistical analysis was not done.

ITT population. Only those participants available at the specified time points were analyze d (represented by n=x, x in the category titles).

This was a tolerability variable, where the participants were instructed to individually assess the right and the left side of the face to indicate the severity that they had experienced during the time period from their last visit for redness. The area on the face was assessed excluding the excluding nose, nasogenian, and superior and inferior eyelids. The assessment of the redness was graded on 0 to 5 scale based on severity by the participant. 0=None, 1=Very minimal, 2=mild, 3= moderate, 4=severe, and 5= Very severe.
