Trial overview
Official title: Study STF115287, a Clinical Confirmation Study of GSK2585823 (Clindamycin 1%-Benzoyl Peroxide 3% Gel) in the Treatment of Acne Vulgaris in Japanese Subjects. - A multicenter, randomized, single-blind, active-controlled, parallel-group study -
Trial description: This is a multicenter, randomized, single-blinded (investigator’s blinded), active-controlled (clindamycin [CLDM] 1% gel), parallel-group study in Japanese subjects with acne vulgaris to demonstrate the efficacy of GSK2585823 (CLDM 1%-benzoyl peroxide [BPO] 3% gel) when applied once or twice daily for 12 weeks. This study will also evaluate the safety of GSK2585823 when applied topically either once or twice daily for 12 weeks.
