Resumen:
Context Semaglutide, a once-weekly glucagon-like peptide-1 analog approved for use in patients with type 2 diabetes (T2D), demonstrated superior body weight (BW) reductions and decreased insulin resistance (IR) vs comparators across the Semaglutide Unabated Sustainability in Treatment of Type 2 Diabetes (SUSTAIN) 1–3 clinical trials. Objective To investigate the relationship between IR and BW across the SUSTAIN 1–3 trials. Design Post hoc analysis of the SUSTAIN 1–3 trials. Setting Three hundred and eleven sites in 30 countries. Patients or other participants 2432 subjects with T2D. Interventions Semaglutide 0.5 or 1.0 mg, placebo or active comparator (sitagliptin 100 mg, exenatide extended release 2.0 mg). Main Outcome Measure To assess the extent of the effect on IR that is mediated (indirect effect) and not mediated (direct effect) by the effect on BW. Results Across SUSTAIN 1–3, mean BW was significantly reduced with semaglutide 0.5 mg (3.7 kg to 4.3 kg; P < 0.0001) and semaglutide 1.0 mg (4.5 kg to 6.1 kg; P < 0.0001) vs comparators (1.0 kg to 1.9 kg). There were greater reductions in IR with semaglutide 0.5 mg (27% to 36%) and semaglutide 1.0 mg (32% to 46%) vs comparators (17% to 28%). Gre...
