Trial summary

Brown adipose tissue (BAT) is unique in its capability to convert chemical energy directly into heat. Active BAT increases energy expenditure and can thereby counteract obesity and insulin resistance. Read more about this study

About this study

Brown adipose tissue (BAT) is unique in its capability to convert chemical energy directly into heat. Active BAT increases energy expenditure and can thereby counteract obesity and insulin resistance. Currently, the imaging method of choice to assess BAT morphology and function is 18F-FDG-PET/CT which is expensive and exposes patients or healthy volunteers to ionizing radiation, thus impeding larger prospective studies.

Magnetic resonance imaging (MRI) could constitute a suitable alternative and preliminary small-scale studies are promising.

The overall aim of this research proposal is to develop reliable magnetic resonance imaging techniques to facilitate the study of brown adipose tissue in human adults, specifically in the context of endocrine disease.

Specifically, investigators want to

  1. Develop a reliable MR imaging protocol for human BAT and compare BAT volume to cold induced nonshivering thermogenesis as a measure of BAT activity.
  2. Assess the intra-individual variance of BAT volume measured by MRI.
  3. Evaluate direct measurement of BAT temperature by functional MRI.

What is being measured

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

  1. Correlation of scBAT volume and cold induced thermogenesis as determined by indirect calorimetry

    measurement of scBAT volume and measurement of cold induced thermogenesis as determined by indirect calorimetry, both values measured in a timeframe of two weeks

    Measured: both measurements within 2 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by University Hospital, Basel, Switzerland at 2 sites in Switzerland.

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 3 inclusion and 8 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 6 Apr 2018. 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 Switzerland. 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?

Correlation of scBAT volume and cold induced thermogenesis as determined by indirect calorimetry (time frame: both measurements within 2 weeks). 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 NCT02682706, 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 6 Apr 2018.
