( ater than or equal to 5 percent andtwi...)Safety Analyses of Clinical Data for Bifeprunox in Patients with,Schizophrenia Showed a Favorable Weight and Lipid Profile, Similar,to Placebo,Health

"These analyses of Phase 2 and Phase 3 studies point out the favorable weight and metabolic profile of patients who received bifeprunox," says Earl Sands, M.D., Vice President, Research and Development at Solvay Pharmaceuticals, Inc. "Patients with schizophrenia have a high risk of developing metabolic side effects, including obesity and high cholesterol."

Philip Ninan, M.D., Vice President, Neuroscience at Wyeth Pharmaceuticals, says, "Through our partnership, Wyeth Pharmaceuticals and Solvay Pharmaceuticals are committed to developing investigational medications for mental health conditions. There is a significant need to expand treatment options and to offer individualized therapy for patients with schizophrenia."

In October 2006, Wyeth Pharmaceuticals and Solvay Pharmaceuticals, Inc. announced that a New Drug Application was submitted to the U.S. Food and Drug Administration for bifeprunox, an investigational antipsychotic for the treatment of schizophrenia and for maintenance of stability. Under the terms of a collaboration agreement entered into in March 2004, Wyeth Pharmaceuticals and Solvay Pharmaceuticals agreed to co-develop and co-commercialize bifeprunox and two other compounds, which are in earlier stages of development, as potential treatments for schizophrenia and other psychiatric conditions. The original compound was discovered by Solvay Pharmaceuticals and is being developed by Wyeth, Solvay Pharmaceuticals and Lundbeck.

Under a new agreement that was announced in January 2007, Wyeth Pharmaceuticals and Solvay Pharmaceuticals will collaborate in a joint discovery effort targeting the identification of small molecules as potential antipsychotic medications. Any compounds discovered as part of the research collaboration will be jointly co-owned and co-patented by Wy
