Combo of SGLT2 Inhibitor + GLP-1 RA Boosts Diabetes Survival
The study used data collected in the National VA Database and included 121,156 patients with both type 2 diabetes and established ASCVD. Using propensity-score matching the researchers compiled three subgroups that each included 5,277 matched patients. One subgroup had patients prescribed an SGLT2 inhibitor, a second subgroup included patients on a GLP-1 RA, and a third subgroup had patients on agents from both classes.

Patients included in the analysis averaged about 67 years of age; 97% were men, their average body mass index was about 34 kg/m2, their average A1c was about 7.9%, their average estimated glomerular filtration rate was about 55-66 mL/min per 1.73 m2, and their average left ventricular ejection fraction was about 55%. The database provided a median follow-up of 902 days (about 2.5 years). The prespecified primary endpoint focused on events that occurred during the first year of follow-up, but the investigators also ran a 3-year follow-up analysis on a post hoc basis.

The most common SGLT2 inhibitor received by these patients was empagliflozin. In contrast, the GLP-1 RA drugs that patients received split more widely. The most prescribed agent was liraglutide, semaglutide, and dulaglutide, with fewer than 5% receiving exenatide.

The 1-year incidence of combined ASCVD events including all-cause death, patients on agents from both classes had a significant 46% reduced rate compared with those on an SGLT2 inhibitor only, and a significant 49% reduced rate, compared with those on a GLP-1 RA only. For the endpoint of all-cause death, those on combined treatment had a 1-year rate that was 83% below the rate among patients on only an SGLT2 inhibitor, and 81% below the rate among patients who received a GLP-1 RA but not the other class.
