Introduction: The efficacy and safety of IDegLira and the benefits of its complementary mode of action have been examined in the large global DUAL clinical trial program.
Aim: The aim of this study is to examine the qualitative and quantitative effect of IDegLira compared to the non-fixed adiministration of degludec and liraglutide.
Methods:Uncontrolled type 2 diabetes (T2D) patients (n=473) were included in the study. 158 patients on oral antidiabetic drugs (OADs) switched to OADs and IDegLira (Group A), 163 on OADs and liraglutide switched to degludec and the existing therapeutic regime (Group B) and 152 patients on degludec and OADs switched to liraglutide and the existing treatment (Group C). All patients also received metformin while none of them received sulfonylurea. Follow-up was 12 months and changes in HbA1c, cardiometabolic risk factors, and treatment adherence (with the 8-item Morisky Medication Adherence Scale) were recorded.
Results:There was no difference at baseline between the three Groups as to age (p=0.224), diabetes duration (p=0.322), HbA1c (8.56±1.12, p=0.116) and BMI (32.14±3.56, p=0.142). The mean HbA1c after 12 months was 6.79±0.77, 7.14±1.19, 7.18±1.07 (p=0.033) for Groups A, B and C respectively. More patients achieved the therapeutic target for HbA1c in Group A (p=0.048). The weight change was -3.2±1.2 Kg for Group A, 1.2±1.1 Kg for Group B and -4.3±1.7 Kg for Group C (p<0.001). There was no difference in the hypoglycemic episodes between the three Groups (p=0.251). Greater adherence was achieved in Group A compared to Group B and C (7.58±1.08, 6.38±1.28 and 6.44±1.16, p=0.031). Total insulin dose was lower for Group A (p=0.040).
Conclusions: Uncontrolled patients on oral antidiabetic drugs when switched to a therapeutic regimen with IDegLira achieved a significant improvement in their glycemic control with a significant adherence to their therapeutic regimen while the adherence in a non-fixed combination was not significant enough.
