This cohort study was initiated to emulate the design of the SURPASS-CVOT trial using observational analogues of the trial design components in a study based on insurance claims data.
Recent evidence suggests that the metabolic effects of glucagon-like peptide-1 receptor agonists (GLP-1RA) can be enhanced by combining them with the actions of other entero-pancreatic hormones, such as glucose-dependent insulinotropic polypeptide (GIP) and/or glucagon. Tirzepatide is a once-weekly GIP/GLP-1RA, approved for the treatment of type 2 diabetes in May 2022.
The Study of Tirzepatide Compared With Dulaglutide on Major Cardiovascular Events in Participants With Type 2 Diabetes (SURPASS-CVOT; NCT04255433) is an event-driven, randomized, double- blind, active comparator, parallel-group study, to evaluate cardiovascular (CV) outcomes with tirzepatide treatment in people with type 2 diabetes (T2D) and established atherosclerotic CV disease (ASCVD) compared with dulaglutide treatment, stratified by baseline sodium-glucose cotransporter-2 (SGLT2) inhibitors use. SURPASS-CVOT was designed to establish CV protection with tirzepatide by demonstrating noninferiority of tirzepatide to dulaglutide, and also to determine whether tirzepatide produces a greater CV benefit than dulaglutide (superiority analysis).
This new user active comparator cohort study aims to emulate the SURPASS-CVOT trial using insurance claims data. Trial design parameters were adapted in claims data using observational analogues for eligibility criteria, treatment strategies, treatment assignment, follow-up start, follow-up end, outcome, and causal contrast. We also conducted HbA1c-adjusted analyses among those with HbA1c values (54% of population).
