A Phase 2, Multicenter, Randomized, Double-Blind, Vehicle Controlled, Dose-ranging Study in the Treatment of Acne Vulgaris,

This will be a Phase 2, multicenter, randomized, double-blinded, dose-ranging, parallel arm comparison study in male and non-pregnant female subjects, 9 through 45 years of age (inclusive) with facial acne vulgaris. This dose-ranging study, intended to identify the dose(s), will consist of 7 study visits over 14 weeks:

Inclusion Criteria:

• Males or non-pregnant females 9 to 45 years of age (inclusive) at the time of consent/assent.
• Have a clinical diagnosis of moderate to severe (Grade 3 or 4) facial acne vulgaris, as determined by the Investigator's Global Assessment (IGA).

• Female subject is pregnant, lactating, or is planning to become pregnant during the study.
• Has active nodulocystic acne or acne conglobata, acne fulminans, or other forms of acne (e.g., acne mechanica). In the opinion of the Investigator, the subject has a skin pathology or other medical condition that is clinically significant (e.g., obesity) and will preclude participation in the study.
• Has presence of any skin condition on the face (e.g., rosacea, dermatitis, psoriasis, squamous cell carcinoma, eczema, acnetiform eruptions caused by medications, steroid acne, steroid folliculitis, or bacterial folliculitis) in the opinion of the Investigator that could interfere with the diagnosis or assessment of acne vulgaris or evaluation of the investigational product (IP) or requires the use of interfering topical or systemic therapy.
