Show the study's own words
  • "Each test involves blood draws before and during the meal test, GLP-1Ra or placebo administration, and an ultrasound to measure blood vessel function."
  • "The study team will use B-mode ultrasound to measure flow mediated vasodilation (FMD), a bioassay of endothelial function, during each MMTT."

  • 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

The goal of this study is to determine how a drug class called glucagon-like peptide-1 receptor agonists (GLP-1Ra) affects people during an early stage of Type 1 Diabetes undergoing clinical teplizumab treatment. This study involves giving participants a liquid meal under different conditions and observing how their bodies respond, focusing on blood sugar levels, insulin effectiveness, and blood vessel function. The meal tests are followed by two post-treatment tests, one with the GLP-1Ra drug and the other with a placebo. Each test involves blood draws before and during the meal test, GLP-1Ra or placebo administration, and an ultrasound to measure blood vessel function. The goal is to see if GLP-1Ra can help manage blood sugar levels and improve cardiovascular health in this population.

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