About this study

Official title: The Use of a Mitochondrial Enhancement Treatment in Bipolar Disorder: A Randomized, Placebo-Controlled Trial of Acetyl-L-Carnitine and Alpha-Lipoic Acid for the Treatment of Bipolar Depression

The primary objective of this 15-week clinical trial is to test the hypothesis that treatment with two proven mitochondrial enhancers, acetyl-L-carnitine (ALCAR) and α-lipoic acid (ALA), has significantly greater efficacy than placebo as an augmentation treatment in bipolar depressed patients who display an incomplete response to conventional treatments.

Read the detailed description

The primary objective of this proposed clinical trial is to test the hypothesis that treatment with two proven mitochondrial enhancers, acetyl-L-carnitine (ALCAR) and α-lipoic acid (ALA), has significantly greater efficacy than placebo as an augmentation treatment in bipolar depressed patients who display an incomplete response to conventional treatments. We propose to test this hypothesis by performing a 15-week placebo-controlled, double-blind, parallel group, flexible-dose study investigating the use of ALCAR and ALA as an augmentation to treatment as usual in depressed bipolar patients. We will compare the efficacy of acetyl-l-carnitine (ALCAR) at doses of 1000-3000mg/day and alpha-lipoic acid (ALA) at doses of 600-1800mg/day with placebo on symptom improvement in individuals diagnosed with bipolar disorder type I, current episode depressed. Improvement will be assessed using the 21-Item Hamilton Depression Rating Scale (HAM-D), the Montgomery Asberg Depression Rating Scale (MADRS), the Young Mania Rating Scale (YMRS), and the Clinical Global Impression-Severity and Improvement Scales (CGI-S and CGI-I).

Furthermore, we hypothesize that improvement in depression symptoms following treatment with ALCAR and ALA will be associated with increases in phosphocreatine (PCr), beta-nucleoside triphosphate (β-NTP), and intracellular pH in the anterior cingulate cortex (ACC) both at week 1 and week 12 of treatment.

What is being measured

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

  1. The 25-Item Hamilton Depression Rating Scale.

    Scores could range from 0 - 72 units on a scale, with 0 representing the least number of depressive symptoms and 72 representing the most number of depressive symptoms.

    Measured: Baseline to 15 Weeks

  2. The Montgomery-Asberg Depression Rating Scale

    Scores could range from 0 - 60 units on a scale with 0 representing the least number of depressive symptoms and 60 representing the most number of depressive symptoms.

    Measured: Baseline to 15 weeks

  3. The Young Mania Rating Scale

    The scores could range from 0 - 60 units on a scale with 0 representing the least number of manic symptoms and 60 representing the most number of manic symptoms.

    Measured: Baseline to 15 weeks

  4. Clinical Global Impression-Severity

    Scores could range from 0 - 7 units on a scale, with 0 representing the least severe ("Normal, not at all ill") and 7 representing the most severe ("Among the most extremely ill patients").

    Measured: Baseline to 15 weeks

Secondary outcomes (1)
  1. Phosphorus MRS Scans on 4T Scanner

    Whole brain total NTP levels as measured by a phosphorus MRS scan on the 4T scanner. The data could range from 0 - 1, with 0 representing the lowest NTP level and 1 representing the highest NTP level.

    Measured: Baseline to 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing acetyl-l-carnitine PLUS alpha-lipoic acide 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 4 inclusion and 9 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 18 Jul 2012. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 18 Jul 2012). 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?

The 25-Item Hamilton Depression Rating Scale. (time frame: Baseline to 15 Weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jul 2012.
