About this study

This study will compare the efficacy and safety of Adapalene, 0.1% and vehicle in the treatment of subjects with Acne Vulgaris. This is a multi-center, randomized, double-blind, parallel, vehicle controlled study involving subjects with acne vulgaris meeting pre-specified inclusion/exclusion criteria. Male and female subjects, 12 years of age or older, with 20-50 papules and pustules and 30 to 100 non-inflammatory lesions and have an Investigator's Global Assessment (IGA) score of 3 (Moderate) or 4 (Severe) are eligible for enrollment. One nodule may be present at inclusion. Acne lesions are evaluated on the face only. Subjects presenting with facial and truncal acne vulgaris can participate in this study. Subjects will be randomized in a 1:1 ratio to Adapalene, 0.1% or Vehicle.

Primary outcomes

  1. Co-Primary Endpoint: Success Rate on Investigator's Global Assessment (IGA) From Baseline to Week 12

    Time frame: From Baseline to Week 12

    Success defined as percentage of subjects who achieved at least a two-grade reduction in IGA scale (e.g from moderate to clear or almost clear)at week 12 from baseline, Last Observation Carried Forward, Intent to treat population. The IGA (Investigator Global Assessment) is defined as a 5 point scale (0 to 4). "0" = clear , "1"= almost clear, "2"= mild, "3"= moderate, "4"=severe.

  2. Co-Primary Endpoint: Absolute Change in Total Lesion Count From Baseline to Week 12

    Time frame: Baseline to Week 12

  3. Co-Primary Endpoint: Absolute Change in Inflammatory Lesion Count From Baseline to Week 12

    Time frame: Baseline to Week 12

  4. Co-Primary Endpoint: Absolute Change in NonInflammatory Lesion Counts From Baseline to Week 12

    Time frame: Baseline to Week 12

Secondary outcomes

  1. Mean Percent Change in Total Lesion Count From Baseline to Week 12

    Time frame: From Baseline to Week 12
