Efficacy and Safety of Once-Weekly Semaglutide Versus Once-Daily Sitagliptin as Metformin Add-on in a Korean Population with Type 2 Diabetes

초록

Introduction: Glucagon-like peptide-1 receptor agonists are well-established type 2 diabetes (T2D) treatments. As variations among populations and culture might influence treatment effects, this post hoc analysis evaluates the efficacy and safety of once-weekly (OW) semaglutide in a Korean population.Methods: Korean adults with T2D inadequately controlled on metformin included in a 30-week, phase 3a, international, multicentre trial (NCT03061214) compared OW subcutaneous semaglutide (0.5 mg and 1.0 mg) with once-daily sitagliptin (100 mg). Key endpoints included change in glycated haemoglobin (HbA(1c)) and body weight; additional endpoints assessed proportions of participants reaching targets of HbA(1c) < 7.0% and <= 6.5%, >= 5% weight loss, and a composite endpoint of HbA(1c) < 7.0% without severe/blood glucose-confirmed symptomatic hypoglycaemia and no weight gain.Results: Korean participants (n = 110) showed a greater reduction in HbA(1c) and body weight with semaglutide 0.5 mg (-1.6%, -2.7 kg) and 1.0 mg (-1.8%, -4.8 kg) versus sitagliptin (-0.9%, 0.5 kg). HbA(1c) targets of < 7.0% and <= 6.5% were achieved by more participants treated with semaglutide 0.5 mg (80.0% and 60.0%, respectively) and 1.0 mg (87.5% and 67.5%, respectively) versus sitagliptin (54.3% and 25.7%, respectively); >= 5% weight loss was observed in 42.9% and 65.0% of participants treated with semaglutide 0.5 mg and 1.0 mg versus 0.0% with sitagliptin. The composite endpoint was achieved by 71.4%, 77.5%, and 31.4% of the population in the semaglutide 0.5 mg, 1.0 mg, and sitagliptin group, respectively. No new safety concerns were observed.Conclusion: This analysis confirms efficacy and safety of OW semaglutide (0.5 and 1.0 mg) in a Korean population with T2D.
