A Multi-centre, Single-blind, Parallel Group, Clinical Evaluation of the Efficacy and Safety of Clindamycin 1% / Benzoyl Peroxide 3% and Azelaic Acid 20% in the Topical Treatment of Mild to Moderate Acne Vulgaris

This is a randomized, comparator-controlled, single-blind, parallel-group study. The current study proposes to compare a fixed-dose combination product containing 3% benzoyl peroxide (BPO) and 1% clindamycin against a cream containing 20% azelaic acid for the treatment of facial acne vulgaris. The results of the study will enable a better assessment of the safety and efficacy of the new dose regime (BPO 3% + clindamycin 1%) in comparison to a well established treatment. Based on the data more evidence based recommendations will be possible to improve the treatment of subjects with acne vulgaris. A total of 220 subjects will be enrolled and will have 5 study visits (Day 1, Weeks 2, 4, 8 and 12). The duration of the study will be over 12 weeks.
