What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

  • "Currently, the main methods available to assess BAT activity are PET-CT with 18F-fluorodeoxyglucose, single-photon-emission CT scanning with tracers such as 123 I-meta-iodobenzylguanidine or 99mTc-tetrofosmin, and/or tissue biopsy 17-19.These techniques have distinct disadvantages as they are expensive and require either the administration of radiopharmaceuticals or tissue sampling."

  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

Glucagon like peptide (GLP-1) agonists, such as liraglutide, exenatide, and semaglutide, have been increasingly used as a medication to address the current twin epidemics of diabetes and obesity. Their activities include increasing insulin production by pancreatic beta cells, improving insulin sensitivity in muscles and weight loss. The mechanisms underpinning the weight loss caused by GLP-1 agonists have not yet been fully elucidated, but brown adipose tissue (BAT) appears to play an important role. We propose to assess BAT activity, using infrared thermography camera images, before individuals start weekly administration of semaglutide, at week 2-4, and week 18-20. We hypothesize that this GLP-1 agonist, semaglutide, will cause an increase in BAT activity and a corresponding increase in basal metabolic rate.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
