Quetiapine SR and Divalproex Sodium ER in the Treatment of Anxiety in Bipolar Disorder With Panic Disorder and/or GAD

Bipolar Disorder Clinical Trial

Official title:
A Randomized, Double-blind, Placebo-controlled Study of Quetiapine SR and Divalproex Sodium ER on Anxiety in Bipolar Disorder With at Least Moderately Severe Current Anxiety and Lifetime Panic or Generalized Anxiety Disorder.

Clinical Trial Summary

The specific aim of this study is to evaluate the efficacy, tolerability, and safety of quetiapine SR monotherapy and divalproex sodium ER monotherapy in comparison to placebo in the treatment of ambulatory bipolar disorder with co-morbid lifetime panic disorder or generalized anxiety disorder and current at least moderately severe anxiety.

Clinical Trial Description

This is a randomized, double-blind, placebo controlled, parallel-group, 8-week trial of quetiapine SR monotherapy compared to divalproex sodium ER monotherapy in outpatient subjects with a lifetime bipolar I, II, or not otherwsise specified (NOS) disorder, a lifetime panic or generalized anxiety disorder, and current diagnosis at least moderately severe anxiety symptoms. Approximately 180 subjects will be randomized to obtain 90 subjects who complete the 8-week trial (30 completers per treatment group). This calculation is based on drop out rates in a similar patient population carried out by this group of collaborators. Subjects will be randomized to quetiapine SR or divalproex sodium ER or placebo in a 1:1:1 ratio. No concomitant psychotropic medication will be allowed throughout the study except for prn lorazepam during the first two weeks for the management of affective and anxiety symptoms, prn zolpidem and zaleplon for the management of insomnia and benztropine for the management of extrapyramidal side effects (EPS). Throughout the study, psychiatric scales will be used to assess psychiatric symptoms and the presence of treatment-emergent adverse events will be monitored and recorded. ;
