ASTRAZENECA RECEIVES FDA APPROVAL FOR SEROQUEL IN BIPOLAR MANIA

Wilmington, Delaware - AstraZeneca announced today that the U.S. Food and Drug Administration (FDA) has approved SEROQUEL (quetiapine) as a monotherapy and adjunct therapy for the treatment of mania associated with bipolar disorder (manic-depressive illness). SEROQUEL has been indicated for the treatment of schizophrenia since 1997. The FDA's approval is based on the positive results of a comprehensive bipolar disorder clinical trial programme involving more than 1,000 patients in 28 countries that found SEROQUEL to be effective across a broad range of symptoms and well-tolerated in treating manic episodes as both a monotherapy and in combination with lithium or divalproex.1,2,3,4SEROQUEL was also found to be fast-acting as improvements in patients' manic symptoms were seen within the first week of treatment. 1,2,3,4 "The new indication for SEROQUEL marks an important milestone for the millions of people who suffer from bipolar disorder," said Dr. Trisha Suppes, Bipolar Disorder Clinic and Research Director, University of Texas Southwestern Medical Center. "With its favourable side-effect profile, SEROQUEL offers patients an excellent option to help improve symptoms of manic episodes associated with bipolar disorder." Bipolar disorder is a serious mental illness that affects approximately 3-4% of the adult population and is the sixth leading cause of disability in the world.5,6,7,8 Side effects associated with treatment, such as extrapyramidal symptoms (EPS) which cause movement disorders or serum prolactin elevation which may cause menstrual irregularities, decreased libido and impotence, can often cause patients great distress and lead to issues with treatment compliance. A lack of compliance results in the patient subjecting themselves to a high risk of relapse and increased risk of suicide, therefore, a well tolerated and effective treatment is pivotal to the successful treatment of this condition. SEROQUEL has also recently received approval from the Mutual Recognition Procedure (MRP) involving 14 European countries to extend its use to treat mania associated with bipolar disorder. Health authority approvals have also been received in the UK, Italy, Mexico and New Zealand. "With this latest approval of SEROQUEL in the U.S., a greater number of patients around the world will be able to benefit from this medication," said Dr. Jamie Mullen, Senior Director of Clinical Research at AstraZeneca. "AstraZeneca is committed to providing medicines that help patients with mental illness and Seroquel is an excellent example of the company's dedication to finding effective treatments that patients can accept." Data from the clinical trial programme was presented in September 2002 at the 3rd European Stanley Foundation Conference on Bipolar Disorder in Freiburg, Germany and in June this year at the International Conference on Bipolar Disorder (ICBD), Pittsburgh, USA.1,2,3,4 The results confirmed that SEROQUEL monotherapy is as effective as current treatments for bipolar disorder and offers improved tolerability benefits.1,2 In the adjunct setting, SEROQUEL was found to be significantly more effective than mood stabilisers alone in the treatment of bipolar mania.4 Across the mania trials, Seroquel was associated with a favourable weight profile and an incidence of EPS (including akathisia) no different from placebo across the full dose range.1,2,3,4 AstraZeneca is a major international healthcare business engaged in the research, development, manufacture and marketing of prescription pharmaceuticals and the supply of healthcare services.
