  Purpose

The primary objective is to test the hypothesis that Quetiapine XR (Extended Release) monotherapy and adjunctive therapy is effective in the acute treatment of bipolar depression and comorbid generalized anxiety disorder in patients with bipolar disorder with or without a substance use disorder. The secondary aim is to generate an estimate of effect size to power a definitive large-scale, multi-site collaborative R01 and to configure the use of the primary and secondary outcome measures in the definitive large-scale study.

Primary Outcome Measures:
  • Change in the 17 Item Hamilton Rating Scale for Depression (HAM-D-17) Score [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]
    A score of 0-7 is considered to be normal. Hamilton Rating Scale total score ranges from 0-57 where higher scores are indicative of more depression.


Secondary Outcome Measures:
  • Response Rate (≥ 50% Improvement) on Hamilton Rating Scale for Depression (HAM-D-17) [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]
    A score of 0-7 is considered to be normal. Hamilton Rating Scale total score ranges from 0-57 where higher scores are indicative of more depression.

  • Remission Rate (≤ 7) on Hamilton Rating Scale for Depression (HAM-D-17) [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]
    A score of 0-7 is considered to be normal. Hamilton Rating Scale total score ranges from 0-57 where higher scores are indicative of more depression. Remission is defined by the number of participants with Hamilton Rating Scale for Depression score equal to or less than 7.

  • Change in Clinical Global Impressions of Improvement or Severity (CGI-I or S) Score [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]

    The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment.

    1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill.


  • Change in the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Score [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]
    This assessment degree of enjoyment and satisfaction experienced by subjects in various areas of daily functioning. The minimum raw score on the Q-LES-Q-SF is 14, and the maximum score is 70 with a higher score indicating less enjoyment and satisfaction.

  • Change in Hamilton Rating Scale for Anxiety (HAM-A) [ Time Frame: Week 0 - Week 8 ] [ Designated as safety issue: No ]
    The scale consists of 14 items, each defined by a series of symptoms, and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety).Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where <17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe

Detailed Description:

120 subjects aged 18 and up with Diagnostic and Statistical Manual -IV Generalized Anxiety Disorder and Bipolar Disorder type I or II as identified by extensive clinical interview and the Mini-International Neuropsychiatric Interview (MINI) will be enrolled and randomized. Assignment to each arm will be balanced for BP I vs BP II; male vs female; and with vs without SUD. Potential participants will be recruited by means of Institutional Review Board -approved advertising or from the clinical psychiatric infrastructure.

This study is a randomized, double-blind, placebo-controlled, 8-week comparison of quetiapine sustained-release monotherapy or adjunctive mood stabilizer therapy vs. placebo in the acute treatment of comorbid generalized anxiety disorder in patients with bipolar disorder with or without a substance use disorder. Subjects will be assessed weekly for mood changes and side effects.
