Bifeprunox: update on registration submission plan following clinical phase III results

EU submission plan for bifeprunox now 2008

Solvay Pharmaceuticals announces today that Solvay and its European partner H Lundbeck A/S will initiate additional phase III comparative clinical work in order to satisfy European Union requirements.  The European registration dossier will be submitted during 2008.

Currently available clinical results in patients with schizophrenia show that bifeprunox has significant antipsychotic activity and was generally well-tolerated .  Solvay and Lundbeck have established an effective and rewarding co-operation on this project, and have mutually agreed the way forward and the new European registration plan.

As previously announced, Solvay and US partner Wyeth Pharmaceuticals are continuing to assess and analyze the clinical study data with respect to a U.S. filing in 2006.

BIFEPRUNOX is a novel compound (a D2 and 5-HT1A partial agonist), for the treatment of psychosis and mood disorders, such as schizophrenia and bipolar disorder.
