Aim: To our knowledge, this is the first real-world study to investigate the safety and effectiveness of a glucagon-like peptide-1 receptor agonist in Chinese patients with type 2 diabetes mellitus (T2DM).
Materials and methods: This prospective, observational, post-marketing study conducted at 46 hospitals in China included adults with T2DM prescribed dulaglutide in routine clinical practice. The primary endpoint was the incidence of treatment-emergent adverse events (TEAEs) and serious AEs in patients who received ≥1 dose of dulaglutide, for up to 24 weeks. Exploratory endpoints included changes in patient-reported glycated haemoglobin (HbA1c) and body weight. Post hoc analyses and multivariate regression were also performed.
Results: From 20 January 2020 to 24 November 2021, 3291 patients received dulaglutide and entered the safety analysis. TEAEs were reported in 1333 (40.5%) patients; the most commonly reported were nausea (n = 193, 5.9%), diarrhoea (n = 183, 5.6%) and decreased appetite (n = 179, 5.4%). serious AEs were reported in 160 (4.9%) patients. TEAEs led to treatment discontinuation in 212 (6.4%) patients. The mean absolute change in HbA1c from baseline to week 24 was -1.65% (p < .001). Greater reductions in HbA1c at week 24 were observed in patients with T2DM duration ≤5 years (p = .002), baseline HbA1c ≥8.5% (p < .001), and without atherosclerotic cardiovascular disease (p = .002). The mean absolute change in body weight from baseline at week 24 was -2.62 kg (p < .001).
Conclusion: Dulaglutide showed a safety profile consistent with previous reports and significantly reduced HbA1c in a real-world setting. These findings support the clinical use of dulaglutide and inform the individualized treatment of patients with T2DM in China.
