About this study
Official title: Open-Label Study of Equetro for the Treatment of Mania in Children Ages 6-12 With Bipolar I, Bipolar II, and Bipolar Spectrum Disorder
This is an open-label pilot study of up to 1200 mg/day of carbamazepine ER (Equetro) in the treatment of children who meet DSM-IV criteria for Bipolar I, Bipolar II, or Bipolar Spectrum Disorder. The main goal of this study is to begin to address the void of information on safety, tolerability and effectiveness of Equetro in the treatment of Pediatric Bipolar Disorder.
Read the detailed description
Initial clinical evidence suggests that carbamazepine (CBZ) may play a therapeutic role in the management of pediatric bipolar disorder. A recent study found that nearly 50% of patients taking immediate-release CBZ had side effects while only 20% of patients had side-effects after switching to an extended release (ER) version of the drug, despite high doses. In addition, with an ER formulation of CBZ there is a potential for decrease in peak-related side effects and improved efficacy with higher blood levels. Thus, an ER formulation of CBZ may improve effectiveness and adherence to treatment.
The goal of this pilot study is to evaluate the safety and effectiveness of Equetro in the treatment of bipolar I, bipolar II, and bipolar spectrum disorder in children ages 6-12 over the course of 8-weeks. We propose that during this exploratory study there will be sufficient safety, tolerability, and effectiveness of Equetro in the treatment of Pediatric Bipolar Disorder. The results of this study will be used to generate hypotheses for a larger randomized controlled clinical trial with explicit hypotheses and sufficient statistical power.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing carbamazepine ER (Equetro) in people with Bipolar Disorder and Mania, 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 10 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 22 Jun 2010. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
symptom reduction measured by YMRS (time frame: 8 weeks). 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 22 Jun 2010.
