GLP-1Ra Impact on Metabolic Outcomes in Stage 2 T1DM While Receiving Teplizumab

Optimizing Stage 2 T1DM Management: Assessing the Impact of GLP-1Ra on Metabolic Outcomes in Patients Receiving Teplizumab


Sponsor

Vanderbilt University Medical Center

Enrollment

24 participants

Start Date

Jun 12, 2024

Study Type

INTERVENTIONAL

Conditions

Summary

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.
