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.

Project description:BACKGROUND:The majority of therapies have generally targeted fasting glucose control, and current mealtime insulin therapies have longer time action profiles than that of endogenously secreted insulin. The primary purpose of this study was to assess both glucose time-in-range (TIR: 70-180?mg/dL) and postprandial glucose excursions (PPGE) in 1-4?h using a real-time continuous glucose monitor (CGM) with Technosphere insulin (TI) versus insulin aspart in patients with type 1 diabetes (T1DM) on multiple daily injections (MDI). RESEARCH DESIGN AND METHODS:This pilot, investigator-led, collaborative, open-label, multicenter, clinical research trial enrolled 60 patients with T1DM with HbA1c levels ?6.5% and ?10%. Individuals were randomized to treatment with titrated TI (n?=?26) or titrated insulin aspart (n?=?34), stratified by baseline HbA1c levels (?8% or >8%). All were required to wear a real-time CGM throughout the trial. All patients in the TI group were advised to take supplemental inhalations at 1 and 2?h after meals if indicated based on postprandial glucose (PPG) values. The coprimary outcomes were assessed both in the full intent-to-treat population and in those individuals randomized to TI who were compliant with supplemental doses ?90% of the time (n?=?15). The CGM data were analyzed using linear regression models. RESULTS:Overall, those treated with TI versus aspart achieved comparable TIR, but less time spent in hypoglycemia (<60 and <50?mg/dL, both P?<?0.05). In the TI-compliant group (n?=?15), TIR was significantly greater (62.5%?±?2.6% vs. 53.8%?±?1.7%, P?=?0.009) and time in hyperglycemia >180?mg/dL was lower (34.2%?±?2.7% vs. 41.0%?±?1.7%, P?=?0.045) as compared with the aspart group. PPG was also significantly lower in the TI cohort at 60 and 90?min postmeal, and PPGE were lower in the TI-compliant group as compared with the aspart group over 1-4-h postmeal (P?<?0.05). In addition, there was weight gain in the aspart group compared with weight loss in the TI group (P?=?0.006) despite higher prandial TI insulin dose. CONCLUSIONS:We conclude that using TI appropriately at mealtimes with supplemental dosing improves prandial glucose (TIR and 1-4?h) control without any increase in time in hypoglycemia or weight gain in patients with T1DM on MDI. The study results support a larger study using a treat-to-target design to confirm these findings. Clinical trial reg. no. NCT03143816, clinicaltrials.gov .
