Aims/Introduction: The short-term efficacy and safety of insulin degludec (IDeg) in patients with type 2 diabetes have not previously been reported. We evaluated target glycemic control and glucose variability in hospitalized patients with type 2 diabetes.
Material and Methods: In an open-label, multicenter, randomized controlled trial, 74 patients were randomly assigned to an insulin glargine U100 (IGla) group (38 patients) or insulin degludec group (36 patients) and were administered Basal-bolus therapy during hospitalization. Continuous glucose monitoring was performed on Day 11 after the insulin treatment commenced, to verify that day’s glucose variability.
Results: The proportion of patients achieving a fasting blood glucose level of 110 mg/dl and 2-hour postprandial blood glucose level of 180 mg/dl throughout at least a day during the observation period was 30.6% [95% confidence interval 18.2-45.5%, one-sided p-value = 0.057] (11/36) in the IGla group, and 31.3% [95% confidence interval 18.0-47.2%, one sided p-value = 0.056] (10/32) in the IDeg group. Although no significant difference was noted on the 6-point SMBG profiles in mean blood glucose levels between the groups, the IDeg group showed a significant improvement in the percentage change from baseline of mean blood glucose before lunch on Day 7 (p = 0.021) and after dinner on Day 12 (Day 7 before lunch: IGla group -29.5 ± 26.3%, IDeg group -44.5 ± 22.1%, p = 0.021; Day 12 after dinner: IGla group -34.2 ± 22.5%, IDeg group -51.1 ± 21.7%, p = 0.021). No significant differences were noted between the groups in the incidence of hypoglycemia or the glucose variability parameter data on continuous glucose monitoring.
Conclusion: This study suggests that IDeg is comparable with IGla in short-term efficacy and safety for patients with type 2 diabetes in the initial phase of basal-bolus therapy.
