Summary:

      To compare the efficacy and safety of quetiapine fumarate given as mono-therapy or adjunct
      therapy to lithium in the treatment of patients with acute mania in bipolar disorder.
      Patients with a documented clinical diagnosis of bipolar mania according to DSM-IV criteria
      (296.4X Bipolar I Disorder, Most Recent Episode Manic; 296.0X Bipolar I Disorder, Single
      Manic Episode) are required to have a YMRS total score of ≥20 at enrolment and randomisation
    

Eligibility criteria:

        Inclusion Criteria:

          -  Provision of written informed consent before initiation of any study related
             procedures. Patients who are deemed incapable of providing informed consent maybe
             enrolled if written informed consent has been obtained from the patient's Legally
             Authorized Representative.

          -  Documented clinical diagnosis meeting the DSM-IV criteria for any of the following:

          -  296.4X Bipolar I Disorder, Most Recent Episode Manic

          -  296.0X Bipolar I Disorder, Single Manic Episode

          -  Have a YMRS score of at least 20 and a score of at least 4 on 2 of the following 4
             YMRS items both at enrolment and at randomisation: Irritability, Speech, Content, and
             Disruptive/Aggressive Behaviour.

          -  Female patients of childbearing potential must have a negative urine pregnancy test at
             enrolment and be willing to use a reliable method of birth control, i.e., barrier
             method, oral contraceptive, implant, dermal contraception, long-term injectable
             contraceptive, intrauterine device, or tubal ligation, during the study.

          -  Be able to understand and comply with the requirements of the study, as judged by the
             investigator.

        Exclusion Criteria:

          -  Manic episode judged to be either:

          -  the direct physiological consequence of a treatment or medical condition other than
             Bipolar disorder.

          -  the direct physiological effect of a substance of abuse; intoxication with
             hallucinogens, inhalants, opioids, or phencyclidine and related substances.

          -  the direct physiological effect of psychostimulant or antidepressant medication.

          -  Evidence of clinically severe or active disease, or a clinical finding that is
             unstable or that, in the opinion of the investigator, would be negatively affected by
             the study medication or that would affect the study medication.

          -  History of seizure disorder, except febrile convulsions.
