Paris, France and Uxbridge, London - 8 April 2008 - The European Commission has granted marketing authorisation for ABILIFY^® (aripiprazole) in the treatment of moderate to severe manic episodes in Bipolar I Disorder and for the prevention of a new manic episode in patients who experienced predominantly manic episodes and whose manic episodes responded to ABILIFY treatment.¹

The approval decision follows a positive opinion adopted on 21 February 2008 by the European Committee for Medicinal Products for Human Use. The CHMP submission is based on data from eight randomised clinical trials carried out in over 2,400 people, which have confirmed the efficacy, safety and tolerability of ABILIFY in the treatment of moderate to severe manic episodes in Bipolar I Disorder and for the prevention of a new manic episode in patients who experienced predominantly manic episodes and whose manic episodes responded to ABILIFY treatment.^2-9

ABILIFY received its first EU approval for the treatment of schizophrenia in 2004.

The commercial launch of ABILIFY in Bipolar I Disorder in the countries of the European Union is expected to begin in the second quarter of 2008.

Bipolar I Disorder

Bipolar I Disorder is characterised by the occurrence of one or more Manic Episodes or Mixed Episodes. A Manic Episode is defined by a distinct period during which there is an abnormally and persistently elevated, expansive, or irritable mood. The mood disturbance must last for at least 1 week (unless hospitalisation is required). A Mixed episode is characterised by a period of time (lasting at least 1 week) in which the criteria are met both for a Manic Episode and a Major Depressive episode.¹⁰ Untreated manic episodes generally last three to six months and depressive episodes generally last six to 12 months without treatment.¹¹
