Evaluate the effects of semaglutide 2.4 mg on cardiometabolic risk factors in people with overweight/obesity without diabetes in the STEP 1 and 4 trials.STEP 1 and 4 were phase III, 68-week, placebo-controlled trials of semaglutide 2.4 mg once weekly combined with lifestyle intervention; STEP 4 had a 20-week semaglutide run-in and 48-week randomized withdrawal period. Participants had a body mass index ≥30 kg/m2 or ≥27 kg/m2 with ≥1 weight-related comorbidity, without diabetes. Pre-specified endpoints were changes in waist circumference, systolic/diastolic blood pressure (SBP/DBP), lipids, fasting plasma glucose (FPG), fasting serum insulin and antihypertensive/lipid-lowering medication use. Post-hoc assessments included non-high-density lipoprotein (HDL) cholesterol, homeostatic model assessment of insulin resistance (HOMA-IR; STEP 1 only), atherosclerotic cardiovascular disease (ASCVD) risk (ACC/AHA algorithm; STEP 1 only) and cardiometabolic risk factors by weight loss achieved (<5%, 5-<10%, 10-<15% or ≥15%) (STEP 1 only).Of the 1961 participants in STEP 1 and 803 in STEP 4, most had ≥1 complication/comorbidity at baseline, with dyslipidaemia and hypertension most prevalent. In STEP 1, reductions in waist circumference, SBP, DBP, FPG, fasting serum insulin, lipids, and HOMA-IR were greater with semaglutide versus placebo (P ≤ 0.001). Reductions in SBP, non-HDL cholesterol, low-density lipoprotein cholesterol and FPG were generally greater with semaglutide than placebo within weight-loss categories. Non-significant ASCVD risk reductions were observed with semaglutide versus placebo (P > 0.05). In STEP 4, improvements in waist circumference, SBP, FPG, fasting serum insulin and lipids during the semaglutide run-in (week 0-20) were maintained over week 20-68 with continued semaglutide, but deteriorated following switch to placebo (P < 0.001 [week 20-68]). Net reductions in antihypertensive/lipid-lowering medication use occurred with semaglutide versus placebo (both trials).Semaglutide may improve cardiometabolic risk factors and reduce antihypertensive/lipid-lowering medication use versus placebo in adults with overweight/obesity without diabetes. These potential benefits were not maintained after treatment discontinuation. This article is protected by copyright.
