The trial

How NCT03101930 was run

This project tests the principle hypothesis that stable glucagon like peptide-1 (GLP-1) analogues have specific GLP1R-dependent beneficial effects on vascular endothelial function, fibrinolysis and inflammation in obesity that exceed the benefits of weight loss, and that genetic or other individual factors that modulate GLP1R sensitivity can modify the effect of these analogues on cardiovascular risk.

  • liraglutide: Subjects in the liraglutide group will receive subcutaneous liraglutide (0.6 mg/d for one week, 1.2 mg/d for one week, and then 1.8 mg/d for 12 weeks) and oral placebo.
  • sitagliptin: Subjects in the sitagliptin group will receive subcutaneous placebo daily and sitagliptin 100 mg/d orally for 14 weeks.
  • hypocaloric diet: Subjects in the hypocaloric diet group will be given a caloric goal designed to achieve a weight loss similar to that expected in the liraglutide treatment arm based on his or her resting energy expenditure. Subjects will be provided counseling and written instructions on how to achieve their daily caloric goal, including use of their own mobile phone applications to monitor caloric intake. To assure compliance with the prescribed caloric goal, subjects will meet with the study dietitian every...
