Outcome Measures

Primary Outcomes (2)

  • Percentage of Participants With >=50% Improvement From Baseline in Clinical Global Impression for Bipolar Disorders Overall Severity

    0-7 scale: rated on the following seven-point scale:) 0=not assessed, 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients. This rating is based upon observed and reported symptoms, behavior, and function in the past seven days.

    Baseline and 8 weeks

  • Percentage of Participants With Clinical Global Impression for Bipolar Disorders Overall Severity Remission (Score <=2 at Week 8)

    0-7 scale: rated on the following seven-point scale:) 0=not assessed, 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients. This rating is based upon observed and reported symptoms, behavior, and function in the past seven days.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must meet criteria for DSM-IV TR diagnosis of bipolar II disorder, as assessed by the structured clinical interview mood modules (SCID) (First et al., 1996).
  • Must be hypomanic as rated by a \>12 on the YMRS on two consecutive visits 1-3 days apart. And meet DSM IV TR criteria for hypomania
  • Must be experiencing depressive symptoms as rated by \> 14 on the MADRS rated at two consecutive visits 1-3 days apart and experiencing depressive symptoms for at least a seven-day period.
  • Must be on stable medication regimens for at least two weeks, or on no medication at study entry.
  • Must be men or women age 18-65 years of age.
  • Must be able to give informed consent.
  • Must be able to comprehend and satisfactorily comply with protocol requirements.
  • If sexually active, females of child-bearing potential must be using a reliable method of contraception, which includes hormonal contraceptives, double-barrier methods (e.g., condom and foam, condom and diaphragm), intrauterine devices (IUD), or tubal ligation. Oral hormonal contraception is allowed as long as no other medications are being used that could decrease hormone levels and put the patient at risk for developing pregnancy.

You may not qualify if:

  • Receiving any atypical antipsychotics (washout period to be determined by treating psychiatrist)
  • Receiving recognized antidepressant medication (within five half-lives), including serotonin reuptake inhibitors, venlafaxine, bupropion, or nefazodone.
  • Receiving carbamazepine (within five half-lives).
  • Experienced a hypomanic episode judged to be a direct physiological consequence of any medical condition or treatment, including neurological disorders, cardiovascular disease, metabolic or autoimmune conditions.
  • Evidence that the patient is likely to need additional concomitant medical therapy during the trial.
  • Participated in another trial of an investigational drug/device \*or received clozapine within 30 days prior to baseline.
  • Known hypersensitivity to Seroquel or any of its components.
  • Known intolerability or past history of ineffectiveness of Seroquel.
  • Met DSM-IV TR criteria for any substance or alcohol abuse or dependence disorder within the past month.
  • History or evidence of unstable medical condition or known clinically significant abnormal laboratory results.
  • Known or suspected chronic infectious disease including HIV or hepatitis.

Limitations and Caveats

Results are limited in their generalizability due to the small sample drawn from two specialty clinics for mood disorders clinical research. Suspected assignment to active quetiapine or placebo possibly influencing ratings on outcome variables
