About this study

Double-Blind, Placebo-Controlled Divalproex Sodium ER in Bipolar I or Bipolar II Depression Previously Diagnosed and Treated as Recurrent Major Depression: This study recruits males and females aged 18 - 70 who currently meet diagnostic criteria for bipolar I or bipolar II disorder and are currently experiencing an episode of major depression. Patients are randomized to double-blind treatment with divalproex sodium ER or placebo and remain in the study for up to six weeks. This six-week double-blind treatment period is followed by an open-label treatment period of six months duration. This study is sponsored by Abbott Laboratories.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Divalproex Sodium ERDrug

    Also called Depakote ER

    Tablets will be available in 250mg and 500mg strengths. Divalproex will be titrated to a minimum blood level of 50 mg/L. However, the investigators will titrate divalproex to the maximum tolerable dose with an expected average dose of 2000mg per day. By dosing in this manner, all subjects will have a minimum blood level of 50 mg/L, but the mean level is likely to be considerably higher.

  • PlaceboDrug

    . Tablets will be available in 250mg and 500mg strengths. Divalproex will be titrated to a minimum blood level of 50 mg/L. However, the investigators will titrate divalproex to the maximum tolerable dose with an expected average dose of 2000mg per day. By dosing in this manner, all subjects will have a minimum blood level of 50 mg/L, but the mean level is likely to be considerably higher.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score

    MADRS total scores range from 0-60, where higher scores are indicative of more depression.

    Measured: Acute phase (week0-week6)

Secondary outcomes (6)
  1. Change in Young Mania Rating Scale (YMRS) Total Score

    YMRS Scores range from 0 to 60 where higher scores are indicative of more mania.

    Measured: Acute phase (week0-week6)

  2. Change in General Behavior Inventory (GBI) Depression Scale Score

    GBI Depression Scale Scores range from 46-184, where higher scores are indicative of more depression.

    Measured: Acute phase (week0-week6)

  3. Change in General Behavior Inventory (GBI) Hypomanic/Biphasic Scale Score

    GBI Hypomanic/Biphasic Scale scores range from 28-112, where higher scores are indicative of more hypomanic/manic symptoms.

    Measured: Acute phase (week0-week6)

  4. Change in Short Form Health Survey (SF-36) Physical Component Summary Score

    SF-36 Physical Component Summary scores range from 0-100, with a higher score indicating better physical health.

    Measured: Acute phase (week0-week6)

  5. Change in Short Form Health Survey (SF-36) Mental Component Summary Score

    SF-36 Mental Component Summary scores range from 0-100, with a higher score indicating better mental health.

    Measured: Acute phase (week0-week6)

  6. Change in Hamilton Anxiety Rating Scale (HAMA) Total Score

    HAMA Scores range from 0 to 56 where higher scores are indicative of more anxiety.

    Measured: Acute phase (week0-week6)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Divalproex Sodium ER in people with Bipolar Disorder, run by University Hospitals Cleveland Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score (time frame: Acute phase (week0-week6)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00194116, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2019.
