Semaglutide Versus Dulaglutide and Liraglutide in Chinese Patients With T2DM : A Multicenter Real‐World Study

Résumé fourni par la source

OBJECTIVE: We aimed to compare the effectiveness and safety of semaglutide 1.0 mg versus dulaglutide 1.5 mg and liraglutide 1.8 mg in patients with type 2 diabetes mellitus (T2DM) under routine clinical care. METHODS: This multicenter, retrospective, real-world study enrolled Chinese adults with T2DM who initiated GLP-1 receptor agonist therapy in endocrinology clinics between January 1, 2022, and August 31, 2024. We compared the effectiveness of these agents on HbA1c and weight loss, with safety as a key exploratory endpoint. Additionally, the UK Prospective Diabetes Study Outcomes Model 2.1 was utilized to project long-term health outcomes. RESULTS: This multicenter retrospective study included 111, 74, and 107 patients treated with semaglutide 1.0 mg, dulaglutide 1.5 mg, and liraglutide 1.8 mg, respectively. After 1:1 propensity score matching, semaglutide demonstrated significantly greater HbA1c reduction compared to both dulaglutide (-0.27% ± 0.70%, p = 0.008) and liraglutide (-0.39% ± 0.87%, p < 0.001), along with higher glycemic target achievement rates. Semaglutide was associated with improved outcomes in all death, cardiovascular death, and other death endpoints. No significant differences in safety profiles were observed among the three treatment groups. CONCLUSIONS: Semaglutide demonstrated superior glycemic control and weight loss compared to both dulaglutide and liraglutide, whereas dulaglutide and liraglutide exhibited comparable clinical efficacy.
