Clindamycin phosphate is the most widely used topical antibacterial agent for acne treatment. Treatment of patients with mild to moderate acne vulgaris with a new foam formulation (clindamycin foam, CF) for 12 weeks was at least as effective as clindamycin gel (CG) based on the Investigator’s Static Global Assessment (ISGA) score. CF was superior to CG based on the reduction from baseline in total (P = .0014), inflammatory (P = .0478), and noninflammatory (P = .0037) acne lesion counts. Additionally, CF achieved efficacy that was superior to that of vehicle foam based on ISGA score (P = .0025) and all 3 lesion counts (all P < .05). Adverse experiences in the active treatment groups were mild or moderate and transient in nature. Thus the foam formulation of clindamycin is a safe and effective acne treatment; the unique foam delivery vehicle may offer cosmetic benefits to the patient and thus increase compliance
