Primary Outcome Measures:
  • Percent change in inflammatory and non-inflammatory lesions from Baseline to Week 12 [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    The mean percent change from Baseline to Visit 5 (End of Treatment) in the inflammatory and non-inflammatory lesion counts.

  • Treatment-emergent adverse events [ Time Frame: 12 Weeks ] [ Designated as safety issue: Yes ]
    All adverse events (AEs) and treatment-emergent AEs reported during the study were summarized for the safety assessment. A treatment-emergent AE was defined as any event not present prior to the initiation of treatment with the investigational products or any event present at Baseline that worsened in either intensity or frequency following exposure to investigational products.

  • Signs and Symptoms of Local Irritation [ Time Frame: 12 Weeks ] [ Designated as safety issue: Yes ]

    Patients will be evaluated for any signs and/or symptoms as separate scores of local irritation, including: erythema, dryness, burning / stinging, erosion, edema, pain, scaling, and itching using the following scale:

    0 = None

    1. = Mild, barely perceptible
    2. = Moderate, distinctive presence
    3. = Severe, marked/intense


Secondary Outcome Measures:
  • The proportion of "success" patients at Visit 5 using the IGE [ Time Frame: 12 Weeks ] [ Designated as safety issue: No ]
    The proportion of "success" patients at Visit 5 using the IGE, where "success" was defined as a two-grade improvement.

  • Mean Percent Change in Total Lesion Count from Baseline to Visit 5 [ Time Frame: 12 Weeks ] [ Designated as safety issue: No ]
    The mean percent change in the total lesion count from Baseline to Visit 5.

Patients must have a minimum of 20 inflammatory lesions and a maximum of 100 and a minimum of 25 and a maximum of 100 non-inflammatory lesions (i.e., open and closed comedones) and no more than 2 nodulocystic lesions (i.e., nodules and cysts) 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.

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.
