Trial summary

Bipolar disorder is a common and often chronic and debilitating mental illness. The depressive phase of bipolar disorder contributes the largest portion of the disorder, and treatment resistant bipolar depression represents a significant public health problem. Read more about this study

About this study

Official title: Riluzole in the Treatment of Bipolar Depression: A Study of the Association Between Clinical Response and Change in Brain Glutamate Levels as Measured by Proton Magnetic Resonance Spectroscopy

Bipolar disorder is a common and often chronic and debilitating mental illness. The depressive phase of bipolar disorder contributes the largest portion of the disorder, and treatment resistant bipolar depression represents a significant public health problem. Recent research has suggested that bipolar depression is associated with elevated brain glutamate activity. We hypothesize that riluzole, a drug approved for ALS which inhibits glutamate activity, will lead to clinical improvement in patients with bipolar depression.

Read the detailed description

We hypothesize that riluzole will lead to significant reduction in depressive symptoms as measured by the Hamilton Depression Rating Scale (HAM-D). Additionally, improvement in depressive symptoms will be associated with reduced glutamate levels in the anterior cingulate cortex, but not parieto-occipital cortex, both at day two and day 42.

What is being measured

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

  1. Change in Hamilton Depression Rating Scale

    The Hamilton Depression rating Scale is a clinician-rated scale that measures the severity of depression symptoms using 21 items. Minimum score is zero and maximum score is 65. Higher scores indicate more severe depressive symptoms.

    Measured: Baseline (week 0) - week 6

Secondary outcomes (3)
  1. Montgomery Asberg Depression Rating Scale

    The Montgomery-Asberg Depression Rating Scale is a clinician-rated scale that measures the severity of depression symptoms. The 10 items measured are apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Minimum score is zero and maximum score is 60. Higher scores represent more severe depressive symptoms.

    Measured: Baseline (week 0) - week 6

  2. Young Mania Rating Scale

    The Young Mania Rating Scale is a clinician-rated scale that measures the severity of mania symptoms. The 11 items measures are elevated mood, increased motor activity, sexual interest, sleep, irritability, speech, language-thought disorder, thought content, aggressive behavior, appearance, and insight. Minimum score is zero and maximum score is 60. Higher scores represent more severe mania symptoms.

    Measured: Baseline (week 0) - week 6

  3. Clinical Global Impression Scale

    The Clinical Global Impression Scale is a clinician-rated scale that evaluates the severity of illness at the time of assessment. The score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).

    Measured: Baseline (week 0) - week 6

Questions about this trial

What is this clinical trial studying?

A study testing Riluzole in people with Bipolar Depression, run by Mclean Hospital 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 3 inclusion and 4 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 7 Aug 2018. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Aug 2010). 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 Hamilton Depression Rating Scale (time frame: Baseline (week 0) - week 6). 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 NCT00544544, 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 7 Aug 2018.
