(HealthDay News) — There are no significant differences in occurrence of cardiovascular disease (CVD) tied to treatment with glucagon-like peptide-1 (GLP-1) receptor agonists compared with dipeptidyl peptidase-4 (DPP-4) inhibitors, second generation sulfonylureas, or insulin, in combination with metformin, according to a study published in Diabetes, Obesity and Metabolism.
Elisabetta Patorno, MD, DrPH, from Brigham and Women’s Hospital in Boston, and colleagues used data from a large U.S. commercial health plan database linked to laboratory test results to identify 3 pairwise 1:1 propensity score (PS)-matched cohorts of type 2 diabetes patients aged at least 18 years treated with metformin who initiated GLP-1 receptor agonists or a comparator — DPP-4 inhibitors (35 534 patients), second generation sulfonylureas (28 138 patients), or insulin (47 068 patients) — between 2005 and 2013.
The researchers found that over 1 year, CVD events per 1000 person-years were similar among PS-matched initiators of GLP-1 receptor agonists vs DPP-4 inhibitors (hazard ratio [HR]=1.02; 95% CI, 0.84-1.24) and among initiators of GLP-1 receptor agonists vs sulfonylureas (HR=0.86; 95% CI, 0.69-1.08).
For GLP-1 receptor agonists vs insulin, results were sensitive to the adjustment for HbA1c, after which the HR was 1.01 (95% CI, 0.73-1.41).
“This large study, performing head-to-head comparisons of GLP-1 receptor agonist vs other antidiabetic agents in real-world patients, provides estimates of relative safety precise enough to rule out large differences in CVD risk and adds further understanding to results from recent clinical trials,” the researchers wrote.
