Patients must have a definite clinical diagnosis of mild to severe acne vulgaris (Grade 2, Grade 3 or Grade 4 on the IGE). 4. Patients must have a minimum of 20 and a maximum of 100 facial inflammatory lesions at baseline. Patients must also have a minimum of 25 and a maximum of 100 non-inflammatory lesions (i. e., open and closed comedones) at baseline. Patients may have no more than two (2) nodulo-cystic lesions at baseline. 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). 5. 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. Alternatively, 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. Alternatively, 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 who have participated in an investigational drug study (i. e., patients have been treated with an investigational drug) within 30 days prior to baseline will be excluded from study participation. Patients who are participating in non-treatment studies such as observational studies or registry studies can be considered for inclusion. 19. Patients who have been previously enrolled in this study will be excluded from study participation. 20.
