About CollaGenex

CollaGenex Pharmaceuticals, Inc. is a specialty pharmaceutical company currently focused on developing and marketing proprietary, innovative medical therapies to the dermatology market. In July 2006, CollaGenex launched Oracea(R), the first FDA-approved systemic product for the treatment of rosacea. CollaGenex's professional dermatology sales force also markets Pandel, a prescription topical corticosteroid licensed from Altana, Inc., Alcortin(R) (1% iodoquinol and 2% hydrocortisone), a prescription topical antifungal steroid combination, and Novacort(R) (2% hydrocortisone acetate and 1% pramoxine HCl), a prescription topical steroid and anesthetic. Alcortin and Novacort are marketed by the Company under a Promotion and Cooperation agreement with Primus Pharmaceuticals, Inc. CollaGenex is conducting two Phase II dose-finding studies to evaluate its second dermatology candidate, incyclinide, for the treatment of acne and rosacea, respectively. CollaGenex is also conducting Phase II clinical trials to evaluate COL-118, a topical compound based on the SansRosa technology, for the treatment of redness associated with rosacea and other skin disorders. CollaGenex recently acquired the rights to develop and commercialize becocalcidiol, a patented Vitamin D analogue developed by QuatRx Pharmaceuticals Company that is currently in Phase II clinical trials for the topical treatment of mild to moderate psoriasis.

Research has shown that compounds can be created by chemically modifying certain tetracyclines and that these new compounds have properties that may make them effective in treating diseases involving inflammation and/or destruction of the body's connective tissues. CollaGenex is evaluating various chemically modified tetracyclines (so called "IMPACS"(TM) compounds because they are Inhibitors of Multiple Proteases And CytokineS) to assess whether they are safe and effective in these applications. The Company has a pipeline of innovative product candidates with possible applications in dermatology and other disease states. In addition, CollaGenex has acquired the SansRosa(TM) technology, which consists of a class of compounds that have shown promise in reducing the redness associated with rosacea, and the Restoraderm(R) technology, a unique, proprietary dermal drug delivery system. CollaGenex plans to leverage these platforms to develop a range of topical dermatological products with enhanced pharmacologic and cosmetic properties.
