A Real-World Evaluation of the Association between Cardiovascular Outcomes and T2D Therapy

Abstract

Data from placebo controlled, randomized clinical trials (RCTs) have demonstrated cardio-protective effects of certain diabetes therapy classes, including sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon receptor agonists (GLP-1RA). However, the majority of these trials made comparisons to placebo and there is limited data on head to head comparisons between specific classes. We performed an observational cohort study using the Truven Health MarketScan® Research Databases (2013-2016) to compare the risk of cardiovascular events between patients initiating treatment with SGLT2is, dipeptidyl peptidase-4 inhibitors (DPP-4is) and GLP-1-RAs vs. sulfonylureas (SUs) in a real-world setting. Propensity score weighting and doubly robust methods (boosting and Poisson regression) were used to control for differences in baseline characteristics. The primary study outcomes were hospitalization for congestive heart failure, acute myocardial infarction, stroke and a composite of all three. Lower extremity amputations were also examined. The relative risks of events in the 12 months before and after treatment initiation were compared to generate relative risk ratios. Protective effects of SGLT2is compared to SUs were observed (Table). Interestingly, there was also a protective effect of DPP-4is on individual outcomes compared to SUs in contrast to DPP-4i vs. placebo in RCTs. Disclosure E. Thiel: None. W.D.
