• The percent (%) change in lesion counts (total, inflammatory, non-inflammatory) from baseline to week 12. [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
• The proportion of subjects who have a SGA score of 0 or 1 at week 12. [ Time Frame: Week 12 ] [ Designated as safety issue: No ]

The purpose of this study is to demonstrate the safety and effectiveness of W0265 gel in subjects with acne vulgaris. The hypothesis is that W0265 is superior to Clindamycin Gel, Tretinoin Gel and Vehicle Gel for the treatment of acne vulgaris.

W0265 gel is a fixed-combination product that addresses the multifactorial factors of acne vulgaris pathogenesis. Based on numerous nonclinical pharmacology studies of each active ingredient, it is expected that this new product will have three biological actions: 1) comedolytic, 2) antimicrobial, and 3) anti-inflammatory.
