The efficacy and safety of tirzepatide, with a special focus on cardiovascular safety, were investigated in the 52-week SURPASS-4 trial testing tirzepatide versus insulin glargine in adults with T2D and a high cardiovascular risk under inadequate glycemic control at baseline on one to three oral glucose-lowering medications (metformin, sulfonylurea, SGLT-2 inhibitor) (74)
