CollaGenex Pharmaceuticals Announces Agreement to Promote
Alcortin™ and Novacort™ to Dermatologists
Newtown, PA, June 8, 2005 – CollaGenex Pharmaceuticals, Inc. (Nasdaq: CGPI) today announced that it had entered into a Promotion and Cooperation Agreement with Primus Pharmaceuticals, Inc., under which CollaGenex will promote Alcortin™ and Novacort™ to dermatologists in the United States. Alcortin (1% iodoquinol and 2% hydrocortisone) is a prescription topical antifungal steroid combination. Novacort (2% hydrocortisone acetate and 1% pramoxine HCl) is a prescription topical steroid and anesthetic. Both products contain a proprietary Biopeptide Aloe Complex™ which is designed to improve skin penetration and help reduce inflammation.
“This is an exciting deal for both companies,” said Colin Stewart, president and chief executive officer of CollaGenex. “Novacort and Alcortin are unique, well differentiated, patented products that present a great opportunity and perfect fit for the CollaGenex professional dermatology sales force. They complement Pandel, our in-licensed mid potency corticosteroid, and will be a very important part of building our dermatology franchise.”
“We are extremely pleased to work with CollaGenex to grow the market for our proprietary products, Alcortin and Novacort,” said J.D. Weir, president and chief executive officer of Primus Pharmaceuticals, Inc. “These products are based on Primus’ patented Biopeptide Aloe Complex composition, which offers great possibilities for further cooperative product development. We believe that CollaGenex, as a premier emerging dermatology company, is the ideal marketing partner as we promote this technology.”
This announcement follows CollaGenex’s report this week of statistically highly significant positive results in phase III clinical trials of Oracea™, its product candidate for the treatment of rosacea.

Research has shown that certain tetracyclines can be chemically modified to retain non-antibiotic 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™” compounds because they areInhibitors ofMultipleProteasesAndCytokineS”) 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 Restoraderm™ technology, a unique, proprietary dermal drug delivery system, and plans to develop a range of topical dermatological products with enhanced pharmacologic and cosmetic properties.
