January 22, 2018 updated by: Joseph Calabrese, MD, University Hospitals Cleveland Medical Center

A Randomized, Double Blind Comparison of Lithium Monotherapy Versus Lithium Plus Divalproex for the Outpatient Management of Hypomania/Mania in Patients With Rapid Cycling Bipolar Disorder Comorbid With Substance Abuse/Dependence

This study will determine the efficacy and safety of combination therapy with divalproex and lithium for treating mania in people with rapid cycling bipolar disorder and a substance abuse disorder.

Detailed Description

Longitudinal Evaluation of the Efficacy and Safety of Divalproex and Lithium in Dual Diagnosis Bipolar Rapid Cycling: This study recruits males and females age 18 and older who currently meet diagnostic criteria for rapid cycling bipolar disorder (type I or II) and who have met the criteria for substance abuse or dependence of cocaine, marijuana and/or alcohol within the past six months. Patients are initially stabilized on dual therapy of lithium and depakote and then randomly assigned to double-blind treatment with either lithium monotherapy or continued dual therapy. Patients remain in the study for six months or until they experience a relapse. Patients in this study are required to bring a friend or family member to all study visits as well as attend chemical dependency services. This study is sponsored by the NIMH. Subjects receive study-related care at no cost.

Description

Inclusion Criteria:

  • To be included in this study, patients will be required to be either acutely hypomanic or manic as defined by the Diagnostic and Statistical Manual -IV (DSM-IV) and meet criteria for current substance abuse and/or dependence disorder within the last six months.
  • Must have 4 or more episodes in the immediate 12 months prior to study entry.
  • Males or females 16 - 65 years of age.
  • A score of 60 or less on the Global Assessment Scale.
  • Have no medical illness precluding the use of lithium or divalproex.

Exclusion Criteria:

  • Patients who have had intolerable side effects to lithium levels 0.8 meq/L or divalproex levels of 50 ug/ml. Patients who have been completely non-responsive to lithium in the past will be excluded, whereas patients who have had partial responses to lithium will be permitted into the study.
  • Patients with a prior history of seizure disorder, cerebral vascular disease, structural brain damage from trauma, clinically significant focal neurological abnormalities, EEG abnormalities with frank paroxysmal activity or a previous CT/MRI scan of the brain with gross structural abnormalities.
  • Patients who require anticoagulant drug therapy.
  • Patients who have uncontrolled gastrointestinal, renal, hepatic, endocrine, cardiovascular, pulmonary, immunological or hematological disease. Patients with alcohol-related liver disease as reflected by diffuse elevations in liver functions tests exceeding the upper limits of the normal range by 50% will be excluded.
  • Patients who are pregnant or plan to become pregnant during the study.
  • Patients who have received haloperidol decanoate or fluphenazine decanoate within the last 10 weeks.
  • Patients who have a central nervous system (CNS) neoplasm, uncontrolled metabolic, demyelinating or progressive disorder; active CNS infection; or any progressive neurological disorder.
  • Patients who are taking exogenous steroids.
  • Patients who do not meet criteria for substance abuse or dependence.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Lithium plus Divalproex
Patients assigned to the combination group were continued on lithium and blinded divalproex.
Lithium monotherapy was initiated at 300 mg twice daily and titrated over 3-6 weeks to minimum blood levels of 0.8 meq/L.
Other Names:
  • Lithium Carbonate
Divalproex was then initiated at 250 mg twice daily and increased over 3-6 weeks to minimum blood levels of 50 ug/ml.
Other Names:
  • Depakote
  • Valproic Acid
Placebo Comparator: Lithium plus placebo
Patients assigned to lithium monotherapy underwent divalproex-placebo substitution at a rate of 250 mg decrements every week until discontinued.
Lithium monotherapy was initiated at 300 mg twice daily and titrated over 3-6 weeks to minimum blood levels of 0.8 meq/L.
Other Names:
  • Lithium Carbonate
Placebo pills that looked exact to divaloproex were provided to subjects and take twice daily.
