The purpose of this project is to determine whether concurrent treatment of patients with major depression (unipolar or bipolar) with triiodothyronine (T3) and sertraline, will lead to a stronger and/or more rapid antidepressant effect than treatment with sertraline alone.

Primary Outcome Measures:
  • Response - HAM-D-21 improvement >50% at 8 weeks
  • Remission - final HAM-D-21 total <7 at 8 weeks

Secondary Outcome Measures:
  • Rate of change in HAM-D-21 scores over 8 week treatment period

Estimated Enrollment: 220
Study Start Date: October 2002
Estimated Study Completion Date: July 2007
Detailed Description:

AIM: To determine the therapeutic efficacy and adverse effects of triiodothyronine (T3) as a supplement to the treatment of bipolar depression (BPD) with a mood stabilizer (MS) (lithium - Li, valproic acid - VPA or carbamazepine - CBZ) and the specific serotonin reuptake inhibitor (SSRI), sertraline; and as a supplement to the treatment of unipolar depression (UPD) with sertraline.

METHOD: A random assignment, double blind, placebo-controlled trial separately evaluating patients with a) BPD who are treated with MS + sertraline + T3 or MS + sertraline + placebo and b) UPD who are treated with sertraline + T3 or sertraline + placebo, for up to 8 weeks in both cases. The design of the trial will permit both the outcome of treatment and the speed of response to be evaluated.
