Objective: Insulin degludec/insulin aspart (IDegAsp) is a soluble coformulation of the novel basal analog insulin degludec (IDeg: 70%) and insulin aspart (IAsp: 30%). We compared the safety and efficacy of IDegAsp, an alternative formulation (AF) (55% IDeg and 45% IAsp), and insulin glargine (IGlar) in insulin-naïve subjects with type 2 diabetes inadequately controlled with oral antidiabetic drugs.Research Design and Methods: In this 16-week, open-label trial, subjects (mean age 59.1 years, A1C 8.5%, BMI 30.3 kg/m(2)) were randomized to once-daily IDegAsp (n = 59), AF (n = 59), or IGlar (n = 60), all in combination with metformin. Insulin was administered before the evening meal and dose-titrated to a fasting plasma glucose (FPG) target of 4.0-6.0 mmol/L.Results: After 16 weeks, mean A1C decreased in all groups to comparable levels (IDegAsp: 7.0%; AF: 7.2%; IGlar: 7.1%). A similar proportion of subjects achieved A1C <7.0% without confirmed hypoglycemia in the last 4 weeks of treatment (IDegAsp: 51%; AF: 47%; IGlar: 50%). Mean 2-h postdinner plasma glucose increase was lower for IDegAsp (0.13 mmol/L) and AF (0.24 mmol/L) than IGlar (1.63 mmol/L), whereas mean FPG was similar (IDegAsp: 6.8 mmol/L; AF: 7.4 mmol/L; IGlar: 7.0 mmol/L). Hypoglycemia rates were lower for IDegAsp and IGlar than AF (1.2, 0.7, and 2.4 events/patient year). Nocturnal hypoglycemic events occurred rarely for IDegAsp (1 event) and IGlar (3 events) compared with AF (27 events).Conclusions: In this proof-of-concept trial, once-daily IDegAsp was safe, well tolerated, and provided comparable overall glycemic control to IGlar at similar low rates of hypoglycemia, but better postdinner plasma glucose control.

Objective: In patients with uncontrolled type 2 diabetes on basal insulin, prandial insulin may be initiated. We assessed the efficacy and safety of initiating insulin degludec/liraglutide fixed-ratio combination (IDegLira) versus basal-bolus insulin., Research Design and Methods: A phase 3b trial examined patients with uncontrolled type 2 diabetes on insulin glargine (IGlar U100) 20-50 units/day and metformin, randomized to IDegLira or IGlar U100 and insulin aspart ≤4 times per day., Results: Glycated hemoglobin (HbA 1c ) decreased from 8.2% (66 mmol/mol) to 6.7% (50 mmol/mol) with IDegLira and from 8.2% (67 mmol/mol) to 6.7% (50 mmol/mol) with basal-bolus (estimated treatment difference [ETD] -0.02% [95% CI -0.16, 0.12]; -0.2 mmol/mol [95% CI -1.7, 1.3]), confirming IDegLira noninferiority versus basal-bolus ( P < 0.0001). The number of severe or blood glucose-confirmed symptomatic hypoglycemia events was lower with IDegLira versus basal-bolus (risk ratio 0.39 [95% CI 0.29, 0.51]; rate ratio 0.11 [95% CI 0.08, 0.17]). Body weight decreased with IDegLira and increased with basal-bolus (ETD -3.6 kg [95% CI -4.2, -2.9]). Fasting plasma glucose reductions were similar; lunch, dinner, and bedtime self-monitored plasma glucose measurements were significantly lower with basal-bolus. Sixty-six percent of patients on IDegLira vs. 67.0% on basal-bolus achieved HbA 1c <7.0% (53 mmol/mol). Total daily insulin dose was lower with IDegLira (40 units) than basal-bolus (84 units total; 52 units basal)., Conclusions: In patients with uncontrolled type 2 diabetes on IGlar U100 and metformin, IDegLira treatment elicited HbA 1c reductions comparable to basal-bolus, with statistically superior lower hypoglycemia rates and weight loss versus weight gain., (© 2018 by the American Diabetes Association.)
