Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 13 to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Subjects must meet DSM-IV-TR criteria for bipolar disorder (type I), and current hypomania, mania, or mixed mania.
  • Subjects must be between the ages of 13 through 18 years.
  • Medications ("treatment-as-usual") stable x2 weeks
  • Subjects must be able to assent to their participation in the study.
  • Subjects must agree to avoid taking supplemental taurine (e.g. from over-the-counter preparations, energy drinks, etc).

Who cannot join

  • Co-morbid serious mental illness.
  • Significant medical or neurological illness, including: seizure disorders, severe respiratory illness or cardiac conditions, known cerebrovascular disease, hypo- or hypertension, diabetes mellitus, and immune, endocrine, renal or hepatic dysfunction (the study team does not wish to enroll any subjects at increased risk for complications or who require additional clinical monitoring due to their medical illness).

About this study

Official title: Taurine as an Anti-Manic Agent: A Double-Blind, Placebo-Controlled Study in Adolescents With Bipolar Disorder

Recently, McLean hospital conducted a 4 month taurine study which showed a reduction in mania ratings. As a follow-up to the preliminary taurine study, and complementary to the currently ongoing double-blind, placebo-controlled trial for taurine in adults with bipolar disorder, this study will target adolescent bipolar subjects (type I) with symptoms of mania or mixed mania. To our knowledge, this would be the first study to evaluate the effects of the novel compound taurine in adolescent subjects with bipolar disorder.

We hypothesize there will be a positive response in some adolescents from taurine treatment, and this positive response will be greater than that expected by chance. This study may demonstrate that taurine is a well-tolerated and effective adjunct treatment for mania in bipolar disorder.

Read the detailed description

A cohort of adolescent (ages 13-18) patients with bipolar disorder and current manic symptoms will be approached for participation in this 3-month outpatient study. Taurine or matching placebo will be administered orally, in capsules, and added to whatever medication(s) the patients are receiving from their clinicians. The specific medications and dosages will be determined solely by the subjects' non-study clinicians ("treatment-as-usual"). During the 3 months of the study, subjects will be required to keep their medications nearly constant (minor dosage adjustments for side-effects or to maintain therapeutic levels will be permitted) for the duration of the trial. Since taurine will be an adjunctive therapy, patients currently taking mood stabilizers can continue to do so. The research team will work closely with the subject and their outpatient clinician(s) to coordinate the medication issues. The results from standard rating scales for bipolar disorder research will be compared between the group receiving the taurine and the group receiving placebo.

The sample will include thirty adolescent (ages 13-18) outpatients with bipolar disorder, type I. The study will be 3 months long.

Study Drugs: The cohort will be randomized to receive either taurine or matching placebo (microcellulose). Taurine and placebo will be provided in 500 mg vegetable capsules.

Follow-up visits and clinical ratings:

During the baseline visit, a detailed psychiatric and medical history will be obtained. The adolescent will start study medicine at that time. The following standard rating scales will be performed:

  1. Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Episode (K-SADS-PL) with additional mood onset and offset items derived from the WASH-U K-SADS (K-SADS-PL-W) (Kaufman 1997).
  2. Young Mania Rating Scale (YMRS; 11 item structured interview; Young et al 1978).
  3. Children's Depression Rating Scale - Revised (CDRS-R; Overholser 1995).
  4. The ADHD Rating Scale (ARS-IV; DuPaul 1998).
  5. Clinical Global Impression scale - Bipolar version (CGI-BP; Guy 1976).
  6. Children's Global Assessment Scale (CGAS; Shaffer 1995).
  7. Montgomery-Asberg Depression rating Scale (MADRS; Montgomery \& Asberg 1979).
  8. Brief Adverse Effect Rating Scale.
  9. Brief Psychiatric Rating Scale for Children (BPRS-C; Overall \& Pfefferbaum 1982).
  10. Safety Assessment (derived from our group's ongoing treatment studies).

After the baseline evaluation, subjects will be evaluated every week for 1 month, and then every 2 weeks for the remainder of the 3 months. The same rating scales will be performed at each follow-up visit, except for the KSADS-PL-W and the ARS-IV. Instead of the full KSADS-PL-W at the follow-up visits, only the screening questions for mania and depression will be performed in order to aid in the determination of syndromic recovery or recurrence. In addition, patients will maintain a daily Mood Diary, which will be reviewed at each study visit to elicit symptom recall.

All ratings will be performed by blind study personnel, who will not know whether the patient is receiving taurine or placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Taurine in people with Bipolar Disorder, run by Cambridge Health Alliance at 2 sites 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 5 inclusion and 6 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: stopped early, as of the sponsor's last update on 3 Feb 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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?

Young Mania Rating Scale (YMRS; 11 item structured interview; Young et al 1978). (time frame: weekly). 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 NCT00391001, which also lists 4 linked publications.

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 3 Feb 2010.
