Total lesion count was the sum of counts of the following lesion types (face only): Papule - raised inflammatory lesions, <0.5 cm in diameter with no visible purulent material; Pustule - raised inflammatory lesions, <0.5 cm in diameter with visible purulent material; Nodule - any circumscribed, inflammatory mass ≥0.5 cm in diameter.
The IGA score is an ordered categorical value ranging from 0 (clear) to 4 (severe). A lower score indicated improvement in the condition. Score 0 (clear): no papules or pustules, no nodules, none or barely perceptible erythema Score 1 (near clear): very few (≤3) papules and/or pustules, no nodules, very mild erythema Score 2 (mild): few papules and pustules present, no nodules, mild erythema Score 3 (moderate): several papules and pustules are the predominant features, ≤2 nodules may be present, moderate erythema Score 4 (severe): numerous papules and pustules, multiple nodules may be present, severe erythema
Treatment responders were defined as participants who have either (1) 2 ordinal or more reductions in the IGA score from baseline or (2) an IGA score of 0 or 1. The IGA score is an ordered categorical value ranging from 0 (clear) to 4 (severe). A lower score indicated improvement in the condition. Score 0 (clear): no papules or pustules, no nodules, none or barely perceptible erythema Score 1 (near clear): very few (≤3) papules and/or pustules, no nodules, very mild erythema Score 2 (mild): few papules and pustules present, no nodules, mild erythema Score 3 (moderate): several papules and pustules are the predominant features, ≤2 nodules may be present, moderate erythema Score 4 (severe): numerous papules and pustules, multiple nodules may be present, severe erythema
Papule - raised inflammatory lesions, <0.5 cm in diameter with no visible purulent material
Pustule - raised inflammatory lesions, <0.5 cm in diameter with visible purulent material
Nodule - any circumscribed, inflammatory mass ≥0.5 cm in diameter
Papules + pustules lesions were the sum of counts of papule (raised inflammatory lesions, <0.5 cm in diameter with no visible purulent material) and pustule (raised inflammatory lesions, <0.5 cm in diameter with visible purulent material) lesions.
Number of participants reporting any adverse event including local tolerability of signs and symptoms of irritation, clinical laboratory safety tests, and vital signs.
Erythema score was evaluated by the investigator on a 0 to 3 scale with a lower score indicating lesser severity. Score 0 (clear): no erythema present Score 1 (mild): slight erythema Score 2 (moderate): definite erythema Score 3 (severe): marked, fiery erythema
