SEROQUEL: New data provides evidence for improvement in anxiety in bipolar depression

June 22, 2004

Alderley Park, UK - June 22, 2004 - AstraZeneca announced important new data presented today at the 24th Collegium Internationale Neuro-Psychopharmacologicum (CINP) meeting in Paris, which show that patients with bipolar depression who are treated with SEROQUEL (quetiapine) experience significant improvement in symptoms of anxiety associated with this stage of the disorder, from as early as the first week of treatment.1

The data from the study show SEROQUEL to be significantly more effective than placebo and well tolerated for the treatment of anxiety symptoms in bipolar depression. Furthermore, the data show that SEROQUEL works quickly to reduce the symptoms of anxiety, having a significant effect on symptoms within the first week of treatment and continuing to improve symptoms throughout the 8 weeks of treatment.1

These new data presented today are from the large-scale, multi-centred, BOLDER trial presented last month at the157th American Psychiatric Association (APA) meeting, which found SEROQUEL to be an effective and well-tolerated agent for the treatment of depressive symptoms associated with bipolar disorder.2

"Many patients with bipolar depression experience intense anxiety, and sometimes this is more disturbing than the depressive symptoms. Symptoms of anxiety are known to be associated with suicide attempts in bipolar disorder. Indeed, anxiety symptoms are frequently the reason why patients seek treatment in the first place.

Therefore, it is important for medications that work in bipolar depression to be effective treatments for anxiety, and that they work quickly and effectively," commented Dr Joseph Calabrese, Co-Director of the National Institute of Mental Health Bipolar Research Center at University Hospitals of Cleveland and Case Western Reserve University School of Medicine, and lead trial investigator. "These data demonstrate that with SEROQUEL, psychiatrists have a potential new treatment for bipolar depression, that is effective and works quickly for both depression and anxiety symptoms."

The BOLDER trial was an 8 week, multi-centred, randomised, double-blind, placebo-controlled study involving 542 patients with a diagnosis of bipolar I or II disorder. Patients received 300mg/day SEROQUEL or 600mg/day SEROQUEL, or placebo. The results of this trial showed:

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.3,4,5,6 Anxiety is commonly experienced in patients with mood disorders such as bipolar disorder and can be identified by a number of different distressing symptoms, that often encourage people to seek treatment for their condition.7 More than half of those with bipolar disorder stop taking their medication at some point during their illness, subjecting themselves to a high risk of relapse and an increased risk of suicide.8 A medication's overall efficacy and tolerability profile is therefore vital to helping patients comply with their medication.

SEROQUEL is licensed in 35 countries for the treatment of mania associated with bipolar disorder, including the US and several European countries. SEROQUEL has been licensed for the treatment of schizophrenia since 1997 and is available in 81 countries. To date, over 4 million people have been treated with SEROQUEL worldwide.
