MARIETTA, Ga. and COLLEGEVILLE, Pa., May 22, 2007 - Solvay Pharmaceuticals, Inc., Wyeth Pharmaceuticals, a division of Wyeth (NYSE:WYE), and Lundbeck A/S presented clinical study results on bifeprunox, an investigational treatment for adult patients diagnosed with schizophrenia, today at the 2007 annual meeting of the American Psychiatric Association. New analyses of six-month data in stabilized adult patients with schizophrenia from a double-blind, placebo-controlled study demonstrated that bifeprunox maintained stability vs. placebo and displayed a favorable weight and lipid profile comparable with placebo.

"Schizophrenia is a chronic, lifelong illness, and long-term management of the illness presents many challenges," comments Daniel Casey, M.D., Professor, Psychiatry and Neurology, Oregon Health and Science University. "Clinicians need new treatment options to help patients manage schizophrenia over the long term."
