  Purpose

Obtain phenotypic data and a DNA/blood sample from mood disorder patients undergoing pioglitazone or quetiapine XR treatment as a part of an IRB approved clinical trial conducted at the Mood Disorders Program. Pioglitazone treatment is examined in metabolic syndrome comorbid with bipolar depression (IRB # 07-08-24) and unipolar depression (IRB # 07-07-20). Quetiapine XR treatment is examined in generalized anxiety disorder comorbid with bipolar depression (IRB # 10-06-19) and unipolar depression (IRB # 12-01-29). Please refer to the respective IRB protocols for more information.

Primary Outcome Measures:
  • Genetic markers associated with treatment response [ Time Frame: Up to 1.5 years ] [ Designated as safety issue: No ]
    Genetic markers in PPARG, 5-HT2A, CYP3A4 and CYP2C8 genes known to be related in the pharmacodynamics and pharmacokinetics of pioglitazone or quetiapine XR will be associated with treatment response.


Estimated Enrollment: 310
Study Start Date: February 2011
Estimated Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Seroquel
Participants who received Seroquel

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

A total of 310 subjects between the ages of 18 and 70 will be targeted for enrollment. We anticipate a low enrollment rate of 200 from the targeted 310 participants. Eligible participants will be diagnosed with DSM-IV bipolar disorder (type I, II, or not otherwise specified) or DSM-IV major depressive disorder, as determined by extensive clinical interview and the Mini-International Neuropsychiatric Interview-Plus (MINI-Plus). Participants will be approached for enrollment if they are currently enrolled in one of four studies: IRB protocol numbers 10-06-19, 12-07-29, 07-07-20, and 07-08-24. Please see these protocols for additional study specific information.
