Objective: Our aim was to compare the efficacy and safety of the combination of clindamycin (1% ) and tretinoin (0.025% ) with each agent alone and vehicle. Methods: Two randomized, double-blind, active drug-and vehicle-controlled 12-week studies evaluated inflammatory and noninflammatory lesion counts and the Investigator s Static Global Assessment in 2219 subjects with acne vulgaris. Results: The combination demonstrated superior efficacy to clindamycin, tretinoin, and vehicle. Combination hydrogel was significantly more effective in reducing inflammatory (P< .005), noninflammatory (P≤ .0004), and total (P< .0001) lesion counts than the other treatments and vehicle. The proportion of subjects with clear or almost clear skin on the Investigator s Static Global Assessment was greater with the combination (P< .0001). Limitations: A majority of subjects (82.6% ) had grade 2-3 acne vulgaris at baseline; therefore these overall results may not be representative of the response in the subjects (17.4% ) with grade 4- 5 acne. Conclusion: The combination clindamycin/tretinoin hydrogel was well tolerated and significantly more effective than clindamycin, tretinoin, or vehicle for the treatment of acne vulgaris. | Leyden J.J.
