Compensation
Not stated
  • 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.

About this study

In plain language

This study looks at how growth hormone affects beta-cells, the cells in the pancreas that make insulin to help control blood sugar. It is for adults ages 18 to 59 with a body mass index (BMI) of 30 to less than 45, with or without a family history of type 2 diabetes. Researchers want to better understand factors linked to the risk of type 2 diabetes.

The purpose of the research study is to better understand how beta-cells (cells in the pancreas that make insulin and help regulate blood sugar) respond to growth hormone in people with a family history of type 2 diabetes at the University of Missouri. Our aim is to advance understanding of how growth hormone affects beta-cells and risk factors for developing type 2 diabetes.

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

Eligibility

Who can join

  • You are 18 to 59 years old.
  • Your BMI, a measure based on height and weight, is 30 to less than 45.
  • For the family history group: a parent, sibling, or child has type 2 diabetes.
  • For the comparison group: you have no family history of type 2 diabetes.

Who can't join

  • You are pregnant, plan to become pregnant during the study, or are breastfeeding.
  • You have or have had type 1 or type 2 diabetes, or a parent, sibling, or child has type 1 diabetes.
  • You take medicines that could affect study results, such as GLP-1 medicines; have had weight-loss surgery; or have an underactive thyroid that is not controlled.
  • You have had high pressure inside the skull, including swelling where the eye's nerve connects, or have a condition that raises this risk, such as Turner syndrome, Prader-Willi syndrome, or reduced kidney function.
  • You have cancer or have been in remission for less than 5 years; have serious anemia (too few healthy red blood cells); or have serious organ problems, such as liver, kidney, or heart disease.
  • You have an alcohol use disorder, use controlled substances, or smoke more than 2 cigarettes a day.
  • You lost more than 3% of your weight in the 3 months before screening, or do moderate or hard exercise for at least 30 minutes without stopping on 3 or more days a week.
  • You have a mental disability, are a prisoner, or cannot freely give informed consent to join the study.
