Summary:

      Enrollment of subjects with mild to moderate facial acne vulgaris.

      Co-Primary efficacy endpoints included:

        -  Absolute change from Baseline to Week 12 in the inflammatory lesion counts on the face

        -  Absolute change from Baseline to Week 12 in the non-inflammatory lesion counts on the
           face

        -  Proportion of subjects with a clinical response of "success" at Week 12 for lesions on
           the face. Success based on IGA is defined as an IGA score of 0 (Clear) or 1 (Almost
           clear) at Week 12 with at least a 2-grade reduction from Baseline.
