148-OR: IDegLira Improves Glycemic Control in Japanese Patients with Type 2 Diabetes (T2D) Uncontrolled on Premixed Insulin Therapy

Abstract

Diabetes management is moving towards choosing therapies that reduce treatment burden, risk of hypoglycemia and weight gain. DUAL VII showed that IDegLira, a fixed-ratio insulin degludec (degludec)/liraglutide combination, had non-inferior A1C lowering, lower hypoglycemia rates, no weight gain and less treatment burden vs. basal-bolus therapy. In contrast, there are no trial data on the efficacy and safety of switching patients (pts) from premixed insulin therapy (with basal and bolus components) to a fixed-ratio combination such as IDegLira. DUAL II Japan (NCT02911948) - a 26 week phase 3a multicenter, randomized, double-blind, treat-to-target trial - compared the efficacy and safety of IDegLira vs. ≤50 U degludec in 210 Japanese pts with uncontrolled T2D (A1C 7.5-11.0%) on 20-50 U basal or premixed insulin therapy + metformin ± an oral antidiabetic drug. Primary analysis confirmed superior change in A1C with IDegLira vs. degludec ≤50, and post hoc analyses found the treatment effect was independent of insulin type at baseline (basal or premixed; interaction test, p=0.5229). This post hoc evaluation describes novel data in a subset of 39 pts who switched from premixed insulin to IDegLira. Mean (standard deviation [SD]) A1C was 8.3% (0.73) at baseline and 6.7% (0.93) at Week 26. Mean (SD) body weight reduced by 1.5 (2.9) kg. Daily insulin dose was 14.1 (3.4) U at baseline and 34.2 (11.5) U at Week 26. Rate of hypoglycemic events (defined as severe or plasma glucose <56 mg/dL) was 2.6 events/patient-year of exposure (52 events in 17 pts). No pts withdrew. This post hoc study is the first to evaluate the switch from premixed insulin to IDegLira, in pts with uncontrolled T2D. IDegLira initiation resulted in improved A1C and weight loss with most pts not experiencing hypoglycemic events. This study offers insight into the effectiveness and safety of switching pts from premixed insulin therapy to IDegLira, and provides a support for further investigation into this transition.
