August 2, 2006 updated by: Abbott

A Randomized, Double-Blind Study of Depakote Monotherapy, Olanzapine Monotherapy, and Combination Therapy of Depakote Plus Olanzapine in Stable Subjects During the Maintenance Phase of Bipolar Illness

The purpose of this study is to assess the efficacy and safety of continued combination therapy using Depakote plus olanzapine, vs. Depakote monotherapy and olanzapine monotherapy in stable subjects during the maintenance phase of bipolar illness.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • DSM-IV-TR primary diagnosis of Bipolar I Disorder as confirmed by the SCID
  • Outpatient receiving treatment with a combination of Depakote plus olanzapine for their bipolar illness and considered clinically stable (e.g., no more than minimal symptoms, no psychiatric hospitalizations, no increase in intensity of clinical interventions) for the preceding 4 months
  • Identified at Screening a most bothersome side effect listed in the UKU which makes switching to monotherapy desirable
  • MRS total score < 12 on two consecutive ratings, separated by at least 5 days (Screening and Day 1)
  • DSS score < 13 on two consecutive ratings, separated by at least five days (Screening and Day 1)
  • CGI-S score < 3 on two consecutive ratings, separated by at least five days (Screening and Day 1)
  • Serum valproate level > 45 mcg/mL, and a maximum allowable dose of Depakote of 3000 mg/day at Screening
  • Olanzapine dose between 5 and 20 mg/day at Screening

Exclusion Criteria:

  • History of schizophrenia or schizoaffective disorder
  • Axis I (e.g., anxiety disorder) or Axis II (e.g., personality disorder) that would interfere with compliance or confound interpretation of study results
  • Has taken antipsychotics, mood stabilizers, or anticonvulsants (unless specifically for seizure control) other than Depakote or olanzapine in the four months prior to randomization. Other psychotropics (e.g., antidepressants, anxiolytics) with the exception of stimulants, that have been used routinely to maintain stability in the preceding four months may be continued, but not increased or decreased
  • Has first manic episode after age 60
  • Has ever taken clozapine
  • Has received depot neuroleptic medication within six months of randomization
  • Urine toxicology screen is positive for phencyclidine (PCP), opiates, cocaine or amphetamines
  • History of active alcohol or substance abuse/dependence within 90 days prior to Screening
  • Known history of non-response to either Depakote or olanzapine monotherapy for the treatment of bipolar disorder
