The FDA approved Finacea^® (azelaic acid) Foam, 15% for the topical treatment of the inflammatory papules and pustules of mild to moderate rosacea. The approval is based on results from two pivotal clinical trials examining the efficacy and safety of Finacea^® Foam compared to its foam vehicle (without the drug azelaic acid) in the topical treatment of papulopustular rosacea. Papulopustular rosacea is a skin disease causing inflammatory lesions (papules and pustules) on the nose, cheeks, chin and forehead. In two pivotal clinical trials, treatment with Finacea^® Foam resulted in a higher Investigator's Global Assessment (IGA) success rate compared to vehicle control (32.1% vs. 23.4% in trial 1 and 43.4% vs. 32.5% in trial 2), as well as a greater reduction in the mean nominal change of inflammatory lesion count from baseline to the end of the 12-week treatment period (-13.2 vs. -10.3 in trial 1 and -13.3 vs. -9.5 in trial 2).
