A Real-World, Prospective, Non-interventional Study of Adults with T2D Switching to IDegAsp from Glargine U100 or U300 in Japan.

ABSTRACT:

Introduction

This real-world study investigated glycaemic control and quality of life (QoL) in insulin-experienced Japanese patients with type 2 diabetes (T2D) who switched to insulin degludec/insulin aspart (IDegAsp).

Methods

This was a prospective, non-interventional, open-label, single-arm study. Eligible patients were adults (aged ≥ 20 years) with T2D, previously treated with insulin glargine 100 or 300 units/mL (glargine U100/U300) with or without prandial insulin, who switched to IDegAsp as part of routine practice. Change from baseline to end of study (EOS; 26 weeks after initiation or IDegAsp discontinuation) in the following endpoints was assessed by adjusted mixed models for repeated measures: glycated haemoglobin (HbA1c; primary endpoint), fasting plasma glucose (FPG), insulin dose and total Diabetes Therapy-Related Quality of Life (DTR-QoL) score. Non-severe hypoglycaemia was assessed in the 4-week period prior to initiating IDegAsp and in the 4-week period before EOS or discontinuation using negative binomial regression.

Results

The full analysis set included 236 patients from 29 centres in Japan with mean (± SD) age 63.2 years (± 12.3), HbA1c 7.7% (± 1.0) and diabetes duration 14.9 (± 9.3) years. After 26 weeks with IDegAsp, HbA1c (estimated change - 0.1% [- 0.2; 0.0]_{95% confidence interval (CI)}, p = 0.3036) and FPG (- 7.5 mg/dL [- 23.5; 8.5]_{95% CI}, p = 0.3477) were maintained; there were significant reductions in basal and total insulin dose: estimated change of - 3.4 units/day [- 3.8; - 3.0]_{95% CI} and - 1.0 units/day [- 1.9; - 0.1]_{95% CI}, respectively (both p < 0.05). Non-severe hypoglycaemia rates were similar in the periods before and after initiating IDegAsp, while there was a significant improvement in total DTR-QoL score after 26 weeks with IDegAsp (p = 0.0012).

Conclusion

These real-world data suggest that switching to IDegAsp from glargine U100 or U300 was well tolerated in a Japanese population with T2D, with no new safety or tolerability signals, and associated with maintenance of glycaemic control and improved QoL.

Project description:IntroductionIn the EDITION clinical trial programme, patients with type 2 diabetes mellitus (T2DM) receiving insulin glargine (IGlar) U300 required 10-15% more insulin than those receiving IGlar U100. This study sought to determine whether this difference was apparent in real-world practice.MethodsIn this observational, retrospective cohort study, electronic medical records in the Big-Pac® database (Real Life Data) relating to adult insulin-naïve patients with T2DM who initiated IGlar U100 or U300 treatment in Spain in 2016-2017 and remained on treatment for 18 months were selected. IGlar U100- and U300-treated patients were matched 1:1 (propensity score matching). The primary analysis compared changes from baseline in mean daily IGlar dose (U and U/kg) at 6 (± 2), 12 (± 2) and 18 (± 2) months between cohorts (paired t tests). Changes in glycated haemoglobin (HbA1c) and weight were analysed descriptively.ResultsThe IGlar U100 and U300 cohorts included 556 matched pairs (46.9% female) with the following mean (standard deviation) values at baseline, respectively: age 63.6 (12.8) versus 63.7 (11.9) years; years since diagnosis 9.5 (1.4) versus 9.5 (1.3); HbA1c 8.8 (1.3) versus 8.7 (1.5) %; weight 84.6 (16.9) versus 84.7 (17.1) kg. Mean IGlar dose at baseline was 0.19 U/kg/day (both cohorts). Patients receiving IGlar U300 showed a greater increase from baseline in IGlar dose at 6, 12 and 18 months [mean dose (U/kg/day) 5.1%, 10.3% and 12.8% greater, respectively, in IGlar U300-treated patients]. Mean HbA1c was 8.1% in both cohorts at 18 months. Mean (SD) weight at 18 months with IGlar U100 and IGlar300 was 86.8 (17.0) kg and 85.0 (17.1) kg, respectively.ConclusionIn real-world practice, insulin dose was significantly higher in IGlar U300-treated than U100-treated patients at 6, 12 and 18 months, with similar reductions in HbA1c. At equal IGlar price/unit in Spain, the increased dose requirements of IGlar U300 would result in higher costs.

Project description:BackgroundThere is an ongoing discussion about possible differences between insulin degludec (IDeg-100) and glargine U300 (IGlar-300). There is little data and head-to-head comparison of IDeg-100 and IGlar-300 regarding their simultaneous impact on glycemic variability and oxidative stress in patients with type 2 diabetes mellitus (T2DM).ObjectiveIn our randomized, open-label, crossover study, we compared the impact of IDeg-100 and IGlar-300 on glycemic variability and oxidative stress in insulin-naive patients with T2DM.MethodsWe recruited a total of 25 adult patients with T2DM (7 females) whose diabetes was uncontrolled (HbA1c ≥7.5%) on two or more oral glucose-lowering drugs; a total of 22 completed the study. Mean age was 57.3 (SD 6.99) years and duration of diabetes was 9.94 (SD 5.01) years. After the washout period, they were randomized alternately to first receive either IDeg-100 or IGlar-300 along with metformin. Each insulin was administered for 12 weeks and then switched. At the beginning and end of each phase, biochemical and oxidative stress parameters were analyzed. On 3 consecutive days prior to each control point, patients performed a 7-point self-monitoring of blood glucose profile. Oxidative stress was assessed by measuring thiol groups and hydroperoxides (determination of reactive oxygen metabolites test) in serum.ResultsIGlar-300 reduced mean glucose by 0.02-0.13 mmol/L, and IDeg-100 reduced glucose by 0.10-0.16 mmol/L, with no significant difference. The reduction of the coefficient of glucose variation also did not show a statistically significant difference. IGlar-300 increased thiols by 0.08 µmol/L and IDeg-100 increased thiols by 0.15 µmol/L, with no significant difference (P=.07) between them. IGlar-300 reduced hydroperoxides by 0.040 CARR U and IDeg-100 increased hydroperoxides by 0.034 CARR U, but the difference was not significant (P=.12).ConclusionsThe results of our study do not show a significant difference regarding glycemic variability between patients receiving either insulin IDeg-100 or IGlar-300, although IGlar-300 showed greater dispersion of data. No significant difference in oxidative stress was observed. In a larger study, doses of insulins should be higher to achieve significant impact on glycemic parameters and consequently on glycemic variability and oxidative stress.Trial registrationClinicalTrials.gov, NCT04692415; https://clinicaltrials.gov/ct2/show/NCT04692415.

Project description:IntroductionThe aim of this study is to demonstrate the real-life effectiveness and safety of insulin glargine 300 U/mL (Gla-300) in patients with type 2 diabetes (T2D) previously uncontrolled on NPH ± prandial insulin or premixed insulins in routine clinical practice in Bulgaria.MethodsThis was a 24-week prospective, observational study performed in 40 inpatient and outpatient sites across the country.ResultsA total of 286 patients were included in the study. The mean age (± SD) was 61.2 ± 10.0 years with duration of diabetes of 11.64 ± 7.5 years and body mass index (BMI) of 32.1 ± 5.7 kg/m2. HbA1c before Gla-300 initiation was 9.8 ± 1.0%, and fasting plasma glucose (FPG) was 13.1 ± 3.4 mmol/L. HbA1c and FPG change from baseline to week 24 was - 1.86% (p < 0.001) and - 4.8 mmol/L (p < 0.001), respectively. The proportion of patients reaching their individualized HbA1c at week 24 was 39.1% (95% CI 33.3-45.1%), while the proportion of patients reaching their individualized HbA1c target without confirmed and/or severe hypoglycaemia was 34.8% (95% CI 29.2-40.7%). At study end, 19.0% (95% CI 14.6-24.1%) achieved HbA1c < 7%. Body weight decreased from 88.3 to 87.0 kg from baseline to week 24 with mean change of - 1.3 kg (p < 0.001). The incidence and event rates of anytime confirmed (≤ 3.9 mmol/L) and/or severe hypoglycaemia were low: 7.7% and 0.42 events per patient-year, respectively. The overall Insulin Treatment Satisfaction Questionnaire (ITSQ) score increased from 53.2 to 78.2 from baseline to week 24 and the difference of 25.1 ± 21.5 points was significant (p < 0.001).ConclusionsIn real-life settings, Gla-300 significantly improved glycaemic control and insulin treatment satisfaction in people with T2D who were inadequately controlled with NPH ± prandial insulin or premixed insulin analogues. Improvement of glycaemic control was associated with a very low risk of hypoglycaemia and with significant weight loss irrespective of the previous insulin regimen.
