A Study Comparing Clindamycin 1%/Benzoyl Peroxide 5% Topical Gel to Duac® Topical Gel in the Treatment of Acne Vulgaris
January 19, 2014 updated by: Taro Pharmaceuticals USA
A Randomized, Double-Blind, Multiple-Site, Placebo-Controlled, Parallel Design Study Comparing Clindamycin 1%/Benzoyl Peroxide 5% Topical Gel (Taro Pharmaceuticals Inc.) to Duac® Topical Gel Clindamycin 1%/Benzoyl Peroxide 5% (Stiefel) in the Treatment of Acne Vulgaris
The objective of this study is to compare the relative efficacy and safety of the test formulation Clindamycin 1%/Benzoyl Peroxide 5% Topical Gel (Taro Pharmaceuticals Inc.) to the marketed formulation Duac® Topical Gel (Clindamycin 1%/Benzoyl Peroxide 5%) (Stiefel) in the treatment of the inflamed lesions of acne vulgaris.
Both the test and reference formulations will also be compared to a placebo formulation to test for superiority.
