About this study

Recent but limited short term studies have shown that Metformin can slow down weight gain in obese children and in children with psychotropic-induced weight gain, two distinct pediatric populations that are at risk for obesity related co-morbid conditions. The purpose of this study is to conduct a long term prospective pilot cohort study to investigate the use of Metformin to prevent or decrease weight gain in two cohorts of children: 1) children with psychotropic induced weight gain on Metformin and 2) children with BMI above the 95th percentile on Metformin. Both study populations will be enrolled in a lifestyle weight management program

Read the detailed description

Approximately 21 percent of children, 12-17 years old are diagnosed with DSM IV disorders, with 11 percent exhibiting severe impairment and 5 percent severe emotional difficulties. By 18 years, 1-5 percent of children are diagnosed with bipolar disorder and up to 20 percent of children with depression. As greater numbers of children and adolescents have been diagnosed with these disorders in the last 10 years, the use of psychotropic drugs in the pediatric populations has increased. Many of the drugs prescribed are the newer antipsychotic drugs olanzapine, risperidone, and quetiapine, referred to as atypical antipsychotics. Compared to the older drugs, such as haldol and thorazine, atypical antipsychotics boast an improved safety profile, with fewer side effects such as tardive dyskinesia, extrapyramidal symptoms and hyperprolactinemia. This advantage has led to providers prescribing antipsychotic more frequently not only for psychotic conditions, but also for other behavioral problems, eg., oppositional defiant disorder, mood disorders, and autism spectrum disorders. In many ways, these medicines are life saving. They protect children from the fate of psychosis, unchecked rage and agitation, allowing the them a chance to grow up more normally.

Our study will provide preliminary evidence for the feasibility of using metformin as an adjunct for weight management in two vulnerable pediatric populations. We will apply for external funding for a large scale randomized clinical trial that will test efficacy of metformin in both our study populations with appropriate comparison groups. In addition, results from our exploratory analysis of patient characteristics eg., insulin level, eating behaviors) that may affect response to treatment will provide a basis to generate further hypothesis for mechanism of action.

Primary objective: Describe and compare the pattern of changes in weight trajectory in the (PIW) and (OME) group.

Secondary Objective: To conduct a preliminary investigation of factors(Baseline BMI, adherence, presence of gastrointestinal side effects, HOMA-IR, eating patterns) that influence the response to metformin.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MetforminDrug

    Also called glucophage, fortamet, glucophage xr, glumetza

    Metformin dosing will be done as is typical in clinical practice. Doses will be titrated at 500mg daily for one week, to a maximum dose of 1000mg twice a day as tolerated by subject.

What is being measured

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

  1. Change in weight

    The change in weight(initial weight-final weight) at 4 weeks, 3 and 6 months. Each patient will have a weight trajectory, z-BMI calculated

    Measured: 6 months

Secondary outcomes (1)
  1. Weight trajectory based on length of intervention and factors that predict response to Metformin

    Weight trajectory based on length of intervention, ie. pattern of weight changes noted over 4 weeks, 3 and 6 months and factors that predict response to Metformin (baseline weight, body mass index, insulin level, HOMA-IR, insulin resistance calculated using fasting glucose to insulin ration

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Metformin in people with Obesity and Weight Gain, run by Nationwide Children's 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 5 inclusion and 4 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 2 Jan 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 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 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?

Change in weight (time frame: 6 months). 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 2 Jan 2019.
