Comparative Effectiveness of Tirzepatide Versus Dulaglutide or Semaglutide on Major Cardiovascular Events in Type 2 Diabetes and Cardiovascular Disease: Insights From Two Target-Trial Emulations

Diabetes CarePublished Two target-trial emulations

Authors' conclusion

Among adults with T2D and ASCVD in routine care, tirzepatide was associated with a lower risk of modified MACE when compared with dulaglutide, driven by reduction in all-cause mortality. Risks of modified MACE seemed similar with tirzepatide and semaglutide.

Study context

Population
Commercially insured adults with T2D and atherosclerotic CVD initiating subcutaneous tirzepatide, dulaglutide or semaglutide (June 2022–December 2024)9,233 and 25,266 matched pairs
Exposure
Tirzepatide vs dulaglutide; tirzepatide vs semaglutide
Outcome
Modified major adverse cardiovascular events (MACE): composite of nonfatal MI, nonfatal stroke and all-cause death
