Title: Efficacy and safety of insulin degludec given as part of basal-bolus treatment with mealtime insulin aspart in type 1 diabetes: a 26-week randomized, open-label, treat-to-target non-inferiority trial. Author: Davies MJ, Gross JL, Ono Y, Sasaki T, Bantwal G, Gall MA, Niemeyer M, Seino H, BEGIN BB T1 Study Group. Journal: Diabetes Obes Metab; 2014 Oct; 16(10):922-30. PubMed ID: 24702700. Abstract: AIMS: The efficacy and safety of insulin degludec (IDeg) was compared with insulin detemir (IDet), both administered once daily (OD) as basal treatment in participants with type 1 diabetes mellitus (T1DM). The primary outcome was non-inferiority of IDeg to IDet in glycated haemoglobin (HbA1c) reduction after 26 weeks. METHODS: This multinational, 26-week, controlled, open-label, parallel-group trial randomized adults with T1DM to IDeg or IDet as OD basal insulin treatment combined with mealtime bolus insulin aspart (IAsp). Participants with T1DM treated with any basal-bolus insulin regimen for ≥ 12 months prior to the trial, a mean HbA1c ≤ 10.0% (85.8 mmol/mol) and body mass index (BMI) ≤ 35.0 kg/m(2) at screening participated in the trial (IDeg: N = 302; IDet: N = 153). RESULTS: After 26 weeks, HbA1c decreased 0.73% (8.0 mmol/mol) (IDeg) and 0.65% (7.1 mmol/mol) (IDet) [estimated treatment difference (ETD) IDeg-IDet: -0.09% (-0.23; 0.05)95% CI (-10.0 mmol/mol [-2.6; 0.6]95% CI ); confirming non-inferiority]. Mean fasting plasma glucose improved in both groups, and was lower with IDeg than IDet [ETD IDeg-IDet: -1.66 mmol/l (-2.37; -0.95)95% CI , p < 0.0001]. The rate of confirmed hypoglycaemia was similar with IDeg and IDet [45.83 vs. 45.69 episodes per patient-year of exposure (PYE); estimated rate ratio (RR) IDeg/IDet: 0.98 (0.80; 1.20)95% CI , p = 0.86]. The rate of nocturnal confirmed hypoglycaemia was lower with IDeg than IDet [4.14 vs. 5.93 episodes per PYE; RR IDeg/IDet: 0.66 (0.49; 0.88)95% CI , p = 0.0049]. Adverse event profiles were similar between groups. CONCLUSION: IDeg administered OD in basal-bolus therapy effectively improved long-term glycaemic control in participants with T1DM with a lower risk of nocturnal confirmed hypoglycaemia than IDet.[Abstract] [Full Text] [Related] [New Search]
