The Qualitative and Quantitative Effect of IDegLira Compared with the Nonfixed Administration of Degludec and Liraglutide

Background: 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 effect of the IDegLira on the glycemic control and the cardiometabolic risk factors compared to the non-fixed adiministration of degludec and liraglutide. Material and Methods: 473 patients with type 2 diabetes mellitus (T2DM) were included in the study. 158 patients on oral antidiabetic drugs (OADs) switched to OADs and IDegLira (Group A), 163 under OADs and liraglutide treatment added degludec to their regimen (Group B) and in 152 patients using degludec and OADs, liraglutide was added (Group C). Follow-up period was 52 ±2 weeks and changes in HbA1c, cardiometabolic risk factors and treatment adherence (with the 8-item Morisky Medication Adherence Scale (MMAS-8)) were recorded. Results: There was no difference at baseline between the three groups as to age (61.88 ± 9.98 years, p =0.212), diabetes duration (12.08 ± 5.83, p = 0.332), HbA1c (mean HbA1c: 8.59± 1.13, p = 0.118) καιΒΜΙ (BMI 32.08 ± 3.22, p = 0.144). Mean HbA1c levels after the follow-up period was 6.79 ± 0.77, 7.14 ± 1.19, 7.18 ± 1.07 (p = 0.033) for Group A, B and C, respectively. Most of patients in Group A reached the treatment target for HbA1c (p = 0.041). 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 groups (p = 0.251). The highest levels of adherence were noticed 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, respectively) while total insulin dose was lower for Group A compared to the other groups (p=0.041). Conclusion: Uncontrolled patients on oral antidiabetic drugs when switched to an IDegLira regimen achieved a significant improvement in their glycemic control and a more significant adherence compared the non-fixed combination of degludec and liraglutide.
