简要总结
The objectives of this study were to compare the safety and efficacy profiles of a generic Azelaic Acid Foam, 15% to the reference listed Finacea® (azelaic acid) Foam, 15% and to demonstrate therapeutic equivalence and safety of the two active foams in the treatment of moderate facial rosacea, and to demonstrate superiority of the Reference and Test products over the Vehicle.
详细描述
Topical azelaic acid is used to treat inflammatory papules and pustules of mild to moderate rosacea. Other topical therapies and oral antibiotics are also used to treat rosacea symptoms. Finacea® (azelaic acid) Foam, 15% contains azelaic acid, a naturally occurring saturated dicarboxylic acid that has proven anti-inflammatory effects, as well as anti-keratinizing and antimicrobial actions.

结局指标
主要结局
Percent Change From Baseline in the Inflammatory Lesions (Papules and Pustules) Counts at Week 12
时间窗: Baseline, 12 weeks
All facial papules, pustules, and nodules, located above the jaw line and extending to the hairline, were counted. When counting facial lesions, lesions present on the nose were included. The total count for each lesion type was recorded and the total number of inflammatory lesions (papules and pustules) were calculated. A papule with a pustule on its apex was counted as a pustule. Counts of nodules and cysts were reported separately and not included in the inflammatory counts. Papule defined as inflammatory lesion; small (≤5 mm in diameter), solid palpable lesion, usually with inflamed elevation of the skin that does not contain pus. Pustule defined as inflammatory lesion; small (≤5 mm in diameter), inflamed skin swelling that is filled with pus. Cyst and nodule defined as palpable solid or soft lesion \>5 mm in diameter.
