109-LB: Comparative Effectiveness of Insulin Glargine 300 U/mL (Gla-300) and Insulin Degludec 100 U/mL (iDeg-100) in Insulin-Naïve Type 2 Diabetes Adults: RESTORE-2 Real-World Study

Abstract

Second generation basal insulin (2BI) provide similar/improved efficacy with better safety compared to first generation BI. Real-world data on 2BI in patients with type 2 diabetes (T2D) are still limited. The study aimed at comparing effectiveness of 2BI (Gla-300 vs. iDeg-100) in insulin-naïve T2D. This was a retrospective, non-inferiority, multicenter study, from electronic medical records. All patients initiating Gla-300 or iDeg-100 in January 2017-2020 were 1:1 propensity score matched. Linear mixed models for repeated measures were applied to assess changes during 6 months in HbA1c, fasting blood glucose (FBG), body weight, and insulin doses. Incidence rates (IR) of hypoglycemic events were compared using Poisson regression models. Overall, 19 centers provided data on 357 patients in each PSM cohort. Estimated mean baseline levels of HbA1c were 9.2%. Marked reductions in HbA1c after 6 months were documented: -1.70%; (95%CI -1.90; -1.50) in Gla-300 group and -1.69%; (95%CI -1.89; -1.49) in IDeg-100 group (between group mean difference: 0.01; 95%CI -0.29; 0.27), confirming non-inferiority of Gla-300 vs. IDeg-100. FBG was reduced by about 60 mg/dl in both groups; minor changes in body weight were documented. In both groups, the mean prescribed dose was about 12 U (0.15 U/Kg) and was slightly titrated during 6 months up to +4U (0.20 U/Kg). IR (episodes per patient-months) of BG≤70 mg/dl was 0.13 (95%CI 0.07;0.26) in Gla-300 group and 0.14 (95%CI 0.07;0.27) in IDeg-100 group (p=0.87). IR of BG<54 mg/dL was 0.02 (95%CI 0.01;0.05) in Gla-300 group and 0.02 (95%CI 0.01;0.04) in IDeg-100 group (p=0.49). No severe hypoglycemic episodes were reported. In T2DM adults, initiation of Gla-300 or IDeg-100 was associated with similar improvements in glycemic control, no weight gain, low hypoglycemia rates, with no severe episodes. These data can contribute in overcoming clinical inertia in BI initiation and dose titration. Disclosure G.
