GLUCOSE-MGH: Understanding Genetic Links and Oral Semaglutide

This study, called GLUCOSE-MGH, aims to understand how your genes affect your body's response to oral semaglutide (Rybelsus), a medication approved for type 2 diabetes. Researchers also want to see how your body reacts to a special breakfast meal before and after taking oral semaglutide. You would take 7 mg of oral semaglutide once daily for 14 days. To join, you need to be between 18 and 65 years old and have blood sugar levels that fall between normal and pre-diabetes. The main goal is to measure how your body's insulin responds to oral semaglutide treatment after 15 days. The study is currently unclear on its recruitment status and plans to enroll 125 participants.

Study design
This is an interventional study planning to enroll 125 participants. It involves taking oral semaglutide and undergoing specific tests.
What's involved
You would have two visits to the clinic. During these visits, you'll have blood drawn multiple times after eating a standardized breakfast meal. You will also take oral semaglutide daily for 14 days between visits.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint for measuring insulin response is at 15 days.

  • Insulin response to oral semaglutide treatment15 days

    Investigators will measure the change in insulin area under the curve (AUC) over 120 minutes of the MMTT, calculated using the trapezoidal method, between Visit 1 and Visit 2 as an index of response to oral semaglutide, and compare this outcome by genotype at selected loci.
