BezafibrateTreatment for Bipolar Depression: A Proof of Concept Study
We propose to test the hypothesis that bezafibrate, a pan-PPAR agonist, may be effective and safe for bipolar depression with the following specific aims:
Aim #1. Proof-of-Concept Safety and Tolerability Aim: To assess the safety and tolerability of bezafibrate added to lithium for bipolar depression, especially with regard to worsening manic symptoms and suicidal ideation.
We will conduct a phase IIa, 8-week, open pilot trial of bezafibrate added to lithium in 20 participants with bipolar depression. We will monitor changes in manic symptoms (Young Mania Rating Scale), suicidal ideation, cognitive functioning specifically in attention and verbal memory, and treatment emergent adverse events (SAFTEE). We will also monitor changes in the Framingham Cardiovascular Risk Score.
Aim #2. Preliminary Assessment of Efficacy: To assess the antidepressant efficacy of bezafibrate added to lithium for acute bipolar I major depressive episodes.
In summary, we propose an 8-week, proof-of-concept open pilot trial of an adjunctive pan-PPAR agonist, bezafibrate, for 20 patients with an acute bipolar I major depressive episode. The study may have a profound impact on the development of a novel treatment consistent with the mitochondrial dysregulation hypothesis of bipolar disorder and, to the best of our knowledge, will be the first proof-of-concept trial to assess a pan-PPAR agonist for bipolar disorder.

|Official Title:||A Pan-PPAR Agonist Treatment for Bipolar Depression: A Proof of Concept Study|
- Change from Baseline to Week 8 in Montgomery-Åsberg Depression Rating Scale (MADRS) [ Time Frame: Baseline and Week 8 ]The primary efficacy measure will be the change in MADRS score.
- Change from Baseline to Week 8 in Clinical Global Impressions Bipolar Scale (CGI-BP-S) score [ Time Frame: Baseline and Week 8 ]Secondary efficacy measure will be change in CGI-BP-S score.
- Adiponectin Level at Baseline and Week 8 [ Time Frame: Baseline and Week 8 ]We will measure adiponectin as a well-established biomarker for the effect of bezafibrate on PPAR and examine changes in adiponectin as a mediator of changes in mood symptoms.

Experimental: Bipolar I Disorder
30 currently depressed patients with DSM-IV bipolar I disorder who are currently taking an adequate dose of lithium (.6 to 1.0 meq/L) will receive Bezafibrate treatment
30 patients with Bipolar I disorder who are experiencing an acute bipolar depressive episode will be given bezafibrate XR 400 mg daily added on to adequate doses of lithium (.6 to 1.0 meq/L).
