  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: Participants who have recently been seen at a community Early Psychosis Intervention (EPI) clinic, or at BC Children's Hospital for first-episode psychosis or bipolar disorder. Age-, sex-, and weight-matched controls will be recruited from the general community.

Who may be able to join

  • Male or female, aged 12+ years for healthy participants or participants with bipolar disorder; or aged 15+ years for participants with non-affective psychosis.
  • Recent admission to hospital for psychiatric services related to first-episode psychosis or first-episode bipolar disorder.
  • Participants being treated with an antipsychotic medication principally for psychosis or for bipolar disorder.
  • Participants taking aripiprazole must be taking a dose of at least 10mg/day for the duration of the study.
  • Participants must have received no more than 12 weeks of total lifetime exposure to antipsychotics.
  • Participants may be in- or outpatients.
  • Participants able to give informed consent, or informed consent through legally authorized representative.

Who cannot join

  • Previous total lifetime exposure to antipsychotics of more than 12 weeks.
  • Previously diagnosed with diabetes mellitus, seizure disorders, mental retardation (IQ < 70), or pregnancy (current or within 3 months postpartum).
  • Participants who have been treated/are currently being treated with mood stabilizers (paroxetine, lithium, or valproic acid). Prior or concurrent use of Selective Serotonin Reuptake Inhibitor antidepressants (other than paroxetine) is acceptable.

About this study

Official title: A Longitudinal Comparison of Aripiprazole vs. Higher Metabolic Risk Antipsychotic Drugs on Adiposity Using MRI

The purpose of this study is to compare abdominal weight gain and fat distribution in people taking aripiprazole versus risperidone or quetiapine, to people not taking any of these antipsychotic medications.

Read the detailed description

Second generation antipsychotic drugs have much greater efficacy for refractory schizophrenia and have much lower propensity to induce motor side-effects. These medications are seeing increased use for indications other than psychosis, and greater use in populations such as adolescents. However, one of the most critical issues in the field of psychiatry today is the overwhelming evidence that chronic use of the second generation antipsychotics can result in metabolic dysregulation, which includes weight gain, hyperlipidemia, and insulin resistance. A recent meta-analysis indicated that switching from other second generation antipsychotics to the antipsychotic drug aripiprazole consistently resulted in significant weight loss and may be an optimal treatment for patients who exhibit drug-induced weight gain. Therefore, we aim to compare metabolic dysregulation (namely abdominal weight gain and fat distribution)in participants taking aripiprazole, to participants who are taking higher-metabolic propensity antipsychotic drugs (such as risperidone or quetiapine), and to healthy participants.

Receives: Drug: Aripiprazole

What is being measured

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

  1. Abdominal distribution of visceral fat versus subcutaneous fat

    Change over time, and between groups, in amounts of visceral and subcutaneous fat as measured by automated segmentation of a magnetic resonance image (MRI).

    Measured: Baseline (within 12 weeks of starting antipsychotic treatment), and 16 weeks later

Secondary outcomes (4)
  1. Fat content of the liver

    Change over time, and between groups, in the amount of fat accumulation in the liver as measured by magnetic resonance spectroscopy (MRS).

    Measured: Baseline (within 12 weeks of starting an antipsychotic), and 16 weeks later

  2. Metabolic measures

    Comparing change in the levels of hemoglobin, fasting lipid levels, adiponectin, leptin, insulin, and glucagon-like peptide 1 (GLP-1).

    Measured: Baseline (within 12 weeks of starting an antipsychotic), and 16 weeks later

  3. Glucose intolerance

    Change over time, and between groups, in ability to tolerate a glucose challenge as measured by an oral glucose tolerance test (OGTT).

    Measured: Baseline (within 12 weeks of starting an antipsychotic), and 16 weeks later

  4. Potential genetic factors of antipsychotic-induced weight gain

    DNA will be extracted and amplified using polymerase chain reaction (PCR), and the presence or absence of certain single nucleotide polymorphisms will be identified by using primers.

    Measured: Sample to be taken after 16 weeks of participation in the study

Questions about this trial

What is this clinical trial studying?

An observational study of Psychotic Disorders and Bipolar Disorder, run by University of British Columbia at 1 site in Canada.

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 7 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: finished, as of the sponsor's last update on 25 May 2016. 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 Canada. 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?

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?

Abdominal distribution of visceral fat versus subcutaneous fat (time frame: Baseline (within 12 weeks of starting antipsychotic treatment), and 16 weeks later). 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 25 May 2016.
