For the purposes of study treatment and evaluation, these lesions should be limited to the facial treatment area. Lesions involving the eyes, angles of the nose (i.e., the lines around your nostrils and under the nostrils) and scalp should be excluded from the count. Patients may have acne lesions on other areas of the body (e.g., on the back).

Female patients of childbearing potential must have been using accepted methods of birth control or must agree to continue to practice abstinence, from 30 days prior to study entry to 30 days after the last administration of study drug. All female patients are considered to be of childbearing potential unless they have been surgically sterilized or have been postmenopausal for at least 1 year. Abstinence is an acceptable method of birth control. Any of the following methods of birth control are acceptable: oral contraceptives, contraceptive patches/implants (e.g., Norplant®) Depo-Provera®, double barrier methods (e.g., condom and spermicide) or IUD. Female patients must have a negative urine pregnancy test at baseline. A negative result of a pregnancy test having a minimum sensitivity of at least 50 mIU/ml for hCG should be obtained.
6. All male patients must agree to use accepted methods of birth control with their partners, from the day of the first dose administration to 30 days after the last administration of study drug. Abstinence is an acceptable method of birth control. Any of the following methods of birth control are acceptable: oral contraceptives, contraceptive patches/implants (e.g., Norplant®), Depo-Provera®, double barrier methods (e.g., condom and spermicide) or IUD.
7. Patients must be willing and able to understand and comply with the requirements of the protocol, including attendance at the required study visits.
8. Patients must be willing to refrain from using any other treatments for acne vulgaris, including antibiotics, other than the investigational product, for acne present on the face. Patients may use other topical acne treatments that do not have significant or measurable systemic absorption for treatment of acne of the back, shoulders and chest (e.g., benzoyl peroxide, salicylic acid).
9. Patients must be in good health and free from any clinically significant disease.
