A Randomized Double Blind Multiple Center Placebo Controlled Study Comparing CLBG and Benzoyl Peroxide Gel 1%/5% to BenzaClin® (Clindamycin 1%/Benzoyl Peroxide 5%) Topical Gel in the Treatment of Acne Vulgaris

This study is to evaluate the therapeutic equivalence and safety of Clindamycin and Benzoyl
Peroxide Gel 1%/5% and BenzaClin® (clindamycin 1%/benzoyl peroxide 5%) Topical Gel

The objectives of this study are to evaluate the therapeutic equivalence and safety of
Clindamycin and Benzoyl Peroxide Gel 1%/5% (Taro Pharmaceuticals Inc.) and BenzaClin®
(clindamycin 1%/benzoyl peroxide 5%) Topical Gel (Sanofi Aventis, US) in the treatment of
acne vulgaris and to demonstrate the superiority of the efficacy of the test and reference
