Centocor Announces Ustekinumab Biologic License Application Accepted for Filing by FDA

Centocor, Inc. announced today that the Biologics License Application (BLA) for ustekinumab (CNTO 1275) has been accepted for review by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with chronic moderate to severe plaque psoriasis. Ustekinumab is a new, human monoclonal antibody with a novel mechanism of action that targets the cytokines interleukin-12 (IL-12) and interleukin-23 (IL-23), naturally occurring proteins that are important in regulating immune responses and that are thought to be associated with some immune-mediated inflammatory disorders, including psoriasis.

"We are pleased by the FDA's acceptance of our Biologics License Application for review of ustekinumab," stated Jerome A. Boscia, M.D., senior vice president, Clinical R&D, Centocor, Inc. "Ustekinumab has yielded promising efficacy and safety results in Phase 3 clinical trials, and we look forward to working closely with the FDA during their ongoing review of this potential new treatment for psoriasis."

Centocor, Inc. announced that it had submitted the BLA for ustekinumab in December 2007 based on its comprehensive development program including data from two large Phase 3 multicenter, randomized, double-blind, placebo- controlled trials involving nearly 2,000 patients that evaluated the safety and efficacy of ustekinumab in the treatment of moderate to severe plaque-type psoriasis. The primary endpoint of both studies was the proportion of patients who achieved at least a 75 percent reduction in psoriasis as measured by the Psoriasis Area and Severity Index (PASI 75). Acceptance of the BLA filing does not mean that a license has been issued for this product nor does it represent any evaluation of the adequacy of the data submitted in the BLA. In December 2007 the Marketing Authorization Application (MAA) for ustekinumab was submitted in Europe and is currently under review by the European Medicines Agency (EMEA).

One-year findings from one of two ustekinumab Phase 3 trials were presented for the first time at the annual meeting of the American Academy of Dermatology this past Saturday, February 2.
