Summary

Primary Aim: To estimate the antidepressant efficacy of simvastatin versus placebo as an adjunct to lithium, valproate, and/or other atypical antipsychotic therapy among individuals with bipolar I disorder in a nonpsychotic major depressive episode.

Hypothesis: Simvastatin will be superior to placebo in improvement of depressive symptoms assessed by the Montgomery-Asberg Depression Rating Scale (MADRS).

Conditions

Interventions

DRUG

Simvastatin

The study uses the Sequential Parallel Comparison design (SPCD), with two 4-week phases: n=30 subjects are randomized 1:1 to simvastatin versus placebo add-on for 4 weeks, with the nonresponders re-randomized 1:1 for a further 4 weeks. The SPCD will allow us to pool data from both phases to estimate the simvastatin treatment effect. Subjects who respond in phase 1, and all subjects who receive simvastatin in phase 1, continue blinded treatment in phase 2 to preserve the blind, but only phase 1 results are analyzed. Dosage for simvastatin or matched placebo 20mg daily for 8 weeks.

DRUG

Placebo

Subjects (n=15) are randomized to placebo add-on for 4 weeks, with the nonresponders re-randomized 1:1 to statin vs placebo for a further 4 weeks. Subjects who respond in phase 1 continue blinded treatment in phase 2 to preserve the blind, but only phase 1 results are analyzed. Dosage for simvastatin or matched placebo 20mg daily for 8 weeks.
