Clinical Efficacy and Parameters Affecting the Response to Dulaglutide Treatment in Patients with Type 2 Diabetes: A Retrospective, Real-World Data Study

초록

IntroductionThis study aimed to investigate the efficacy and clinical factors affecting the glycemic response to dulaglutide in type 2 diabetes (T2D) in a real-world clinical setting.MethodsWe conducted a retrospective study of 234 patients at the Asan Medical Center, Republic of Korea, who had T2D and initiated dulaglutide from June 2016 to December 2017. The primary outcome was the change in glycated hemoglobin (HbA1c) concentration between baseline and 6months after the initiation of therapy. Multivariate regression analysis was used to determine the clinical parameters contributing to a superior glycemic response to dulaglutide.ResultsThe mean age of the patients was 53, and 50% were male. Their mean baseline HbA1c, body mass index and duration of diabetes were 8.8%, 27.6kg/m(2) and 10.2years, respectively. The change in HbA1c between baseline and 6months was -0.92% (95% CI: -1.1% to -0.74%, p<0.001). The reduction in body weight over the same period was -2.1kg (95% CI: -2.9 to -1.3kg, p<0.001). Using multivariate regression analysis, baseline HbA1c was found to be a significant predictor of superior glycemic response to dulaglutide.ConclusionThe use of dulaglutide was associated with a significant reduction in HbA1c and body weight over a 6-month period in a real-world clinical setting. T2D patients with higher baseline HbA1c concentrations were more likely to demonstrate good clinical responses to dulaglutide.
