About this study

Official title: Open-Label Study of N-Acetylcysteine in Children and Adolescents Ages 5-17 With Bipolar I, Bipolar II, and Bipolar Spectrum Disorder

Children between the ages of 5-17 years old who have or display symptoms of emotional dysregulation (explosiveness, mood swings, irritability, and/or violent behavior) are invited to participate in a 12-week research study to determine the effectiveness and safety of the natural treatment N-acetylcysteine (NAC) for children with emotional and behavioral problems. After undergoing a comprehensive evaluation by medical doctors with a specialty in this area, children who are found eligible to participate in this research study will be treated with NAC. Following the evaluation period, this research study requires 12 weekly visits, either in our office or over the phone, in an effort to closely monitor each child's response to the medication. Eligible participants will receive study-related evaluations and weekly study visits with our study doctors at no cost.

Read the detailed description

This will be a 12-week, open-label study of NAC in the treatment of bipolar disorder in children and adolescents. Subjects will include youth ages 5-17 years with a bipolar spectrum disorder (type I, II, or NOS), mixed, manic, or hypomanic state, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition DSM-5 (American Psychiatric Association, 2013). The primary outcome measures will be improvement in manic symptoms as measured by the Young Mania Rating Scale (YMRS) and improvement in depressive symptoms as measured by the Child Depression Rating Scale (CDRS).

Bipolar diagnoses will be made according to the DSM-5 in a clinical evaluation by a Child Psychiatrist and confirmed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Epidemiological Version (K-SADS-E)(Orvaschel, 1994). All subjects must have a YMRS score of at least 15. Only patients who are not responding to their current treatment regimen will be tapered from their medications; youth on concomitant psychiatric medications will be permitted to continue those medications as listed in the concomitant medication section.

What is being measured

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

  1. Mean Change in the Young Mania Rating Scale (YMRS) Score

    The Young Mania Rating Scale (YMRS) consists of 7 items rated on a scale from 0 (symptoms not present) to 4 (symptoms extremely severe) and 4 items rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe).The YMRS score ranges from 0-60. Questions are asked about the last week. A higher score signifies more severe manic symptoms.

    Measured: Baseline and Endpoint (12 weeks or last observation carried forward if dropped prior to week 12)

Secondary outcomes (1)
  1. Mean Change in the Children's Depression Rating Scale (CDRS) Score

    The Children's Depression Rating Scale (CDRS) is a clinician-rated instrument with 17 items scored on a 1 to 5 or 1 to 7 scale. A rating of 1 indicates normal, thus the minimum score is 17. The maximum score is 113. Scores of 20-30 suggest borderline depression. Scores of 40-60 indicate moderate depression.

    Measured: Baseline and Endpoint (12 weeks or last observation carried forward if dropped prior to week 12)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Open-label Treatment with N-Acetylcysteine in people with Bipolar Disorder, run by Massachusetts General 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 6 inclusion and 12 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 4 Nov 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 4 Nov 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?

Mean Change in the Young Mania Rating Scale (YMRS) Score (time frame: Baseline and Endpoint (12 weeks or last observation carried forward if dropped prior to week 12)). 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 NCT02357290, 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 4 Nov 2019.
