Abstract summarized · Quality not appraised
Studied
SURPASS-4 randomized adults with type 2 diabetes and high cardiovascular risk to once-weekly tirzepatide or titrated insulin glargine.
Who / model
Participants had inadequately controlled type 2 diabetes despite oral glucose-lowering medications and established or high cardiovascular risk.
Studied dose & schedule
Dose and schedule have not yet been extracted for this summary.
Found
At one year, tirzepatide lowered HbA1c more than glargine and caused less hypoglycemia; adjudicated cardiovascular events were not increased.
Limits
The trial used an open-label design.
