Inclusion Criteria
2. Male or female, 12 to 40 years of age, inclusive.
3. Definite clinical diagnosis of facial acne vulgaris with an inflammatory lesion (papules and pustules) count between 20 and 50 and a non-inflammatory (open and closed comedones) lesion count between 25 and 100 and no more than 2 nodulocystic lesions (i.e., nodules and cysts) including those present on the nose.
4. Baseline Investigator's Global Assessment Score of 3 (moderate severity) or 4 (severe) on a severity scale of 0 to 4.
5. Willing and able to understand and comply with the requirements of the study, apply the medication as instructed, refrain from use of all other topical acne medication or topical antibiotics during the 12-week treatment period, return for the required treatment period visits, comply with therapy prohibitions, and are able to complete the study.
6. In general good health and free from any clinically significant disease, other than acne vulgaris, that might interfere with the study evaluations.
7. Females of childbearing potential (excluding women who are surgically sterilized or post menopausal for at least 2 years), in addition to having a negative urine pregnancy test, must be willing to use an acceptable form of birth control during the study. For the purpose of this study, the following are considered acceptable methods of birth control: Oral Contraceptives, Contraceptive patches, Contraceptive Injection (Depo-Provera), Contraceptive Implant (Implanon), Vaginal Contraceptive (Nuva-Ring), IUD, hormonal IUD (Mirena); double-barrier methods (e.g. condom and spermicide) and abstinence with a documented second acceptable method of birth control should subject become sexually active. A sterile sexual partner is not considered an adequate form of birth control. Subjects entering the trial that are on hormonal contraceptives must have been on this method for at least 3 months (90 days) prior to the trial and continue the method for the duration of the trial. Subjects who had used hormonal contraception and stopped must have stopped no less than 3 months (90 days) prior to baseline.
