28-week, randomized, multicenter, open-label, parallel-group phase III trial to investigate the efficacy and safety of biphasic insulin aspart 70 thrice-daily injections vs twice-daily injections of biphasic insulin aspart 30 in patients with type 2 diabetes.

ABSTRACT: Aims/Introduction:? An insulin analogue formulation with a 7:3 ratio of rapid-acting and intermediate-acting fractions, biphasic insulin aspart 70 (BIAsp70) was developed to supplement basal insulin between meals and mimic the physiological pattern of postprandial insulin secretion.? We carried out a randomized, open-label study to compare the efficacy and safety profiles of BIAsp70 and an insulin analogue formulation with a 3:7 ratio of rapid-acting and intermediate-acting fractions (BIAsp30) in type 2 diabetes mellitus patients. Patients were randomized and received either thrice-daily BIAsp70 (n?=?145) or twice-daily BIAsp30 (n?=?144) for 28?weeks. The primary end-point was glycated hemoglobin (HbA1c) after 16?weeks of treatment.? Non-inferiority of BIAsp70 vs BIAsp30 was confirmed and superiority was established with a between-group difference (BIAsp70-BIAsp30) in HbA1c after 16?weeks of treatment of -0.35% (95% CI: -0.51 to -0.19; P?

Project description:IntroductionIn a preceding trial comparing two different titration schemes, insulin degludec/insulin aspart (IDegAsp) showed good efficacy for achieving HbA1c <7% when administered twice daily (BID) in patients with uncontrolled type 2 diabetes (T2D). However, poor glycemic control persisted in a minority of patients. The current exploratory trial investigated the efficacy and safety of intensifying IDegAsp BID treatment in these patients by either adding a once-daily (OD) bolus injection of insulin aspart (IAsp) or by switching to a basal-bolus regimen of insulin degludec (IDeg) plus IAsp taken three times a day (TID).MethodA 26-week, randomized, open-label, phase 3b, treat-to-target trial in which 40 patients with T2D who had not reached target HbA1c ≤7.0% following previous 26-week treatment intensification with IDegAsp BID ±3 oral antidiabetic agents (OADs) were randomized (1:1) to receive IDegAsp BID + IAsp OD (n = 20) or IDeg OD + IAsp TID (n = 20).ResultsMean baseline HbA1c was 7.9% in the IDegAsp BID + IAsp OD group and 7.7% in the IDeg OD + IAsp TID group. After 26 weeks, the estimated mean change in HbA1c from baseline was 0.05% points in the IDegAsp BID + IAsp OD group and -0.49% points for IDeg OD + IAsp TID: estimated treatment difference (ETD) [95% confidence interval] 0.54% [0.09; 0.99], p = 0.021. Few achieved HbA1c <7% in IDegAsp BID + IAsp OD (four patients) and IDeg OD + IAsp TID groups (five patients). Fasting plasma glucose, hypoglycemia, and adverse events were similar between groups.ConclusionWhen used as intensification regimens in patients who failed to achieve target HbA1c during 26-week IDegAsp BID treatment, HbA1c improvements were numerically greater with IDeg OD + IAsp TID compared with IDegAsp BID + IAsp OD. No new safety issues were identified. However, the small, selective sample means clinical generalizations should be made with caution.FundingNovo Nordisk. CLINICALTRIALS.Gov identifierNCT01814137.
