Chester Valley Pharmaceuticals

Chester Valley Pharmaceuticals was a specialty pharmaceutical company focused on the development and commercialization of prescription dermatology products. Founded in 2004 and based in Malvern, Pennsylvania, the company built a portfolio of topical therapies addressing common skin conditions. Its lead products included Benziq, a benzoyl peroxide-based treatment for acne, and Atopiclair, a non-steroidal prescription cream for the management of atopic dermatitis. In January 2007, the company was acquired by Graceway Pharmaceuticals, a portfolio company of the private equity firm GTCR, to strengthen its dermatology presence. Following Graceway's bankruptcy in 2011, the assets were eventually acquired by Medicis.
