CollaGenex Pharmaceuticals Provides Update on Examination of Incyclinide Patent Application
Colin W. Stewart, president and chief executive officer of CollaGenex, stated, "We are confident that our '656 patent application includes patentable claims and that a patent will ultimately issue to cover incyclinide. A final rejection by the patent office is not unusual, and as soon as we have analyzed the reasons for this rejection, we will continue examination of this application. While we remain confident that a patent will issue, the continuing examination process may add a few months to our estimates of when examination may be favorably concluded."
CollaGenex recently announced the results of a Phase 2 dose-finding study of incyclinide for the treatment of acne. The study examined 5 mg, 10 mg and 20 mg doses and achieved its objectives by demonstrating a clear dose-response relationship with an excellent side effect profile similar to placebo. CollaGenex is continuing with a placebo-controlled study of a 40 mg dose over a 12 week period, and expects to conclude this study in the fourth quarter of 2007.
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(R), a prescription topical corticosteroid licensed from Altana, Inc., Alcortin(TM) (1% iodoquinol and 2% hydrocortisone), a prescription topical antifungal steroid combination, and Novacort(TM) (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 a 300-patient, Phase II dose-finding study to evaluate its second dermatology candidate, incyclinide, for the treatment of acne. CollaGenex is also conducting Phase I 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.
Research has shown that certain tetracyclines can be chemically modified to remove their antibiotic effects while retaining the 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 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 Restoraderm(R) technology, a unique, proprietary dermal drug delivery system, and plans to develop a range of topical dermatological products with enhanced pharmacologic and cosmetic properties.
