Initiating or Switching to Insulin Degludec/Insulin Aspart in Adults with Type 2 Diabetes: A Real-World, Prospective, Non-interventional Study Across Six Countries

Improved glycaemic control in people with type 2 diabetes initiating or switching to IDegAsp in a real-world setting in China

AIMS

To investigate glycaemic control in Chinese adults with type 2 diabetes (T2D) initiating, or switching to insulin degludec/insulin aspart (IDegAsp), a co-formulation of basal, and bolus insulin, in a real-world setting.

MATERIALS AND METHODS

A 20-week, prospective, single-arm, open-label, non-interventional study was conducted in Chinese adults with T2D initiating, or switching to IDegAsp after anti-hyperglycaemic treatment with oral antidiabetic drugs (OADs), other insulins, or glucagon-like peptide-1 receptor agonists. The primary endpoint was a change in HbA1c from baseline to end of the study; the secondary endpoints included a change in fasting plasma glucose and Diabetes Treatment Satisfaction Questionnaire (DTSQ) score.

RESULTS

Significant reductions were observed in mean HbA1c and fasting plasma glucose, among both the overall population (N = 878; -1.27%-points [95% CI: -1.36; -1.19]; p < 0.0001, and -1.61 mmol/L [95% CI: -1.81; -1.41]; p < 0.0001, respectively), and in subgroups switching from OADs only, or basal, or premix insulins ± OADs. The mean total DTSQ score increased from 26.4 (baseline) to 31.6 (end-of-study). No significant, or unexpected tolerability, or safety issues were observed. Significant reductions were observed in incidence rates of non-severe (rate ratio 0.37 [95% CI: 0.24; 0.59]; p < 0.0001) and nocturnal non-severe (rate ratio 0.45 [95% CI: 0.21; 0.94]; p = 0.0326) hypoglycaemic episodes.

CONCLUSIONS

In a broad, real-world Chinese population of adults with T2D, initiating or switching to IDegAsp was associated with improved glycaemic control and lower rates of hypoglycaemia. The use of IDegAsp could be an effective treatment option for those with suboptimal glycaemic control or therapeutic inertia.

Efficacy, safety and treatment satisfaction of transition to a regimen of insulin degludec/aspart: A pilot study

BACKGROUND

There is a lack of clinical evidence on the efficacy and safety of transitioning from a thrice-daily pre-mixed insulin or basal-prandial regimen to insulin deglu-dec/aspart (IDegAsp) therapy, with insufficient data from the Chinese popu-lation.

AIM

To demonstrate the efficacy, safety, and treatment satisfaction associated with the transition to IDegAsp in type 2 diabetes mellitus (T2DM).

METHODS

In this 12-week open-label, non-randomized, single-center, pilot study, patients with T2DM receiving thrice-daily insulin or intensive insulin treatment were transitioned to twice-daily injections of insulin IDegAsp. Insulin doses, hemoglobin A1c (HbA1c) levels, fasting blood glucose (FBG), hypoglycemic events, a Diabetes Treatment Satisfaction Questionnaire, and other parameters were assessed at baseline and 12-weeks.

RESULTS

This study included 21 participants. A marked enhancement was observed in the FBG level (P = 0.02), daily total insulin dose (P = 0.03), and overall diabetes treatment satisfaction (P < 0.01) in the participants who switched to IDegAsp. There was a decrease in HbA1c levels (7.6 ± 1.1 vs 7.4 ± 0.9, P = 0.31) and the frequency of hypoglycemic events of those who switched to IDegAsp decreased, however, there was no statistically significant difference.

CONCLUSION

The present findings suggest that treatment with IDegAsp enhances clinical outcomes, particularly FBG levels, daily cumulative insulin dose, and overall satisfaction with diabetes treatment.

Switching from Premixed Insulin to Insulin Degludec/Insulin Aspart for the Management of Type 2 Diabetes Mellitus: Implications of a Real-World Study on Insulin Degludec Dosing

INTRODUCTION

When switching from premixed insulin to insulin degludec/aspart (IDegAsp), IDegAsp usually starts at the same dose as the premixed insulin according to limited clinical experience or at a dose according to clinician discretion. The dose of insulin degludec used in the real world after switching has been poorly investigated.

METHODS

A retrospective analysis was conducted on patients with type 2 diabetes who switched from premixed insulin to IDegAsp from October 2016 to December 2023. Repeated measures analysis of variance was used to compare changes in insulin dose, glycated hemoglobin (HbA1c), fasting blood glucose (FBG), and postprandial blood glucose (PBG) before and after switching.

RESULTS

Sixty-six patients with prior low-ratio premixed insulin and 22 with prior mid-ratio premixed insulin were included. Among the low-ratio insulin users, the total daily dose of insulin degludec (IDeg) decreased by 21.43% and 19.05% at 3 and 6 months, respectively, after switching, compared with prior basal insulin dose (both p < 0.001). Conversely, among mid-ratio insulin users, the IDeg daily dose increased by 10.71% and 32.14% at 3 and 6 months, respectively, after switching, compared with prior basal insulin dose (both p < 0.001). In all patients, HbA1c levels decreased by 0.70%, FBG decreased by 1.00 mmol/l, and PBG decreased by 1.61 mmol/l after 6 months of switching (all p < 0.05); the total daily insulin dose and injection frequency significantly decreased after switching (both p < 0.05); age and disease duration did not affect IDegAsp effects on HbA1c reduction.

CONCLUSIONS

In the setting of transition to IDegAsp from premixed insulin, the dose of basal insulin in the premixed formulation can be a valuable reference for adjusting insulin degludec dose. IDegAsp is superior to premixed insulin in blood glucose control with reduced total daily dose and injection frequency. IDegAsp could be the best choice for the management of diabetes in elderly patients.

Initiating or switching to insulin degludec/insulin aspart in a real-world population of adults with type 2 diabetes in Australia: results from a prospective, non-interventional study

BACKGROUND

Insulin degludec/insulin aspart (IDegAsp) is a fixed-ratio co-formulation of insulin degludec and insulin aspart for the treatment of people with diabetes and suboptimal glycaemic control. Few real-world studies of IDegAsp treatment have been conducted. Here, we report results from the Australian cohort of the global ARISE study of real-world IDegAsp use.

AIMS

To investigate glycaemic control and other clinical outcomes in people with type 2 diabetes (T2D) treated with IDegAsp in a real-world setting in Australia.

METHODS

A total of 183 adults with T2D initiating or switching to IDegAsp in the Australian cohort of the open-label, non-interventional ARISE study were followed for 26-36 weeks from August 2019 to December 2020.

RESULTS

IDegAsp was associated with significant reductions from baseline to end of study (EOS) in mean glycated haemoglobin (estimated change -0.8% (95% confidence interval (CI): -1.05 to -0.56; P < 0.0001)), fasting plasma glucose (-1.6 mmol/L (95% CI: -2.49 to -0.63; P = 0.0017)) and body weight (-2.6 kg (95% CI: -3.68 to -1.55; P < 0.0001)). In insulin-experienced patients, the mean total daily insulin dose did not change significantly (estimated change from baseline to EOS 3.8 (95% CI: -3.70 to 11.21; P = 0.3202)). The proportion of patients experiencing hypoglycaemia numerically decreased during the study (non-severe: 14.2-10.9%; nocturnal non-severe: 4.9-2.2%; and severe: 2.2-0%).

CONCLUSIONS

Initiating or switching to IDegAsp in a real-world population of people with T2D in Australia was associated with significant improvements in glycaemic control and body weight, and numerically lower levels of hypoglycaemia compared with baseline.

Initiation or switch to insulin degludec/insulin aspart in adults with type 2 diabetes in India: Results from a prospective, non-interventional, real-world study

Aim

To investigate clinical outcomes in adults with type 2 diabetes (T2D) after insulin degludec/insulin aspart (IDegAsp) treatment in a real-world setting.

Methods

The 26 weeks study involved 1102 adults with T2D who were either initiated with or switched to IDegAsp according to local practice in six countries. It was an open-label, non-interventional study. The primary endpoint was the change in glycosylated haemoglobin (HbA1c) levels from baseline to the end of study (EOS).

Results

From India, 185 adults participated in this study with mean age of 58.1 (10.3) years and 14.4 (8.1) years of mean duration of T2D. Mean HbA1c decreased from 9.8% (1.8) at baseline to 8.2% (0.1) at the EOS; change in HbA1c from baseline [95% CI]: -1.6% (0.1) [-1.8; -1.4], P < 0.0001. There was a significant reduction in mean fasting plasma glucose (FPG) level from 190.0 (65.8) mg/dl at baseline to 141.9 (4.3) mg/dl at EOS; change in FPG from baseline [95% CI]: -52.2 (4.3) mg/dl [-60.7; -43.7], P < 0.0001. There was a numerical reduction in resource utilization related to diabetes and its complications and hypoglycaemic episodes. From baseline to EOS, the participants with outpatient visits (72 to 32) and workdays missed (2 to 0) decreased. Additionally, the number of patient-reported non-severe hypoglycaemic (47 to 8) and severe hypoglycaemic (4 to 1) episodes decreased as well.

Conclusion

Initiation or switching to IDegAsp led to improvement in glycaemic control in real-world population of Indian adults with T2D. This was accompanied by a numerical reduction in resource utilization and patient-reported hypoglycaemia. Clinical trial registration: NCT04042441.

Efficacy and Safety of IDegAsp in a Real-World Korean Population with Type 2 Diabetes Mellitus

BACKGRUOUND

This study investigated the real-world efficacy and safety of insulin degludec/insulin aspart (IDegAsp) in Korean adults with type 2 diabetes mellitus (T2DM), whose insulin treatment was switched to IDegAsp.

METHODS

This was a multicenter, retrospective, observational study comprising two 26-week treatment periods, before and after switching to IDegAsp, respectively. Korean adults with uncontrolled T2DM treated with basal or premix insulin (±oral antidiabetic drugs) were enrolled. The primary objective was to compare the degree of glycosylated hemoglobin (HbA1c) change in each 26-week observation period. The analyses included changes in HbA1c, fasting plasma glucose (FPG), body weight, proportion of participants achieving HbA1c <7.0%, hypoglycemic events, and total daily insulin dose (ClinicalTrials.gov, number NCT04656106).

RESULTS

In total, 196 adults (mean age, 65.95 years; mean T2DM duration, 18.99 years) were analyzed. The change in both HbA1c and FPG were significantly different between the pre-switching and the post-switching period (0.28% vs. -0.51%, P<0.001; 5.21 mg/dL vs. -23.10 mg/dL, P=0.005), respectively. After switching, the rate of achieving HbA1c <7.0% was significantly improved (5.10% at baseline vs. 11.22% with IDegAsp, P=0.012). No significant differences (before vs. after switching) were observed in body weight change, and total daily insulin dose. The rates of overall and severe hypoglycemia were similar in the two periods.

CONCLUSION

In real-world clinical practice in Korea, the change of insulin regimen to IDegAsp was associated with an improvement in glycemic control without increase of hypoglycemia, supporting the use of IDegAsp for patients with T2DM uncontrolled with basal or premix insulin.

Initiating or Switching to Insulin Degludec/Insulin Aspart in Adults With Type 2 Diabetes in the Philippines: Results from a Prospective, Non-interventional, Real-World Study

Objective

Blood glucose levels of the majority of Filipino patients with type 2 diabetes (T2D) remain uncontrolled. Insulin degludec/insulin aspart (IDegAsp) is a fixed-ratio co-formulation of the long-acting basal insulin degludec and the rapidacting prandial insulin aspart. The real-world ARISE (A Ryzodeg® Initiation and Switch Effectiveness) study investigated clinical outcomes across six countries in people with T2D who initiated IDegAsp. This publication presents the clinical outcomes of the Filipino cohort from a subgroup analysis of the ARISE study.

Methodology

This 26-week, open-label, non-interventional study examined outcomes in adults with T2D initiating or switching to IDegAsp (N=185) from other antidiabetic treatments per local clinical guidance.

Results

Compared with the baseline, there was a significant improvement in glycated hemoglobin at the end of the study (EOS) (estimated difference [ED] -1.4% [95% confidence interval -1.7, -1.1]; P <0.0001). Fasting plasma glucose (ED -46.1 mg/dL [-58.2, -34.0]; P <0.0001) and body weight (ED -1.0 kg [-2.0, -0.1]; P = 0.028) were significantly reduced at EOS compared with baseline. IDegAsp was associated with a decrease in the incidence of self-reported healthcare resource utilization. Adverse events were reported in eight (4.3%) participants.

Conclusion

Initiating or switching to IDegAsp was associated with improved glycemic control, lower body weight, and lower HRU for people with T2D in the Philippines. No new, unexpected AEs were reported.

Glycaemic outcomes in hospital with IDegAsp versus BIAsp30 premixed insulins

BACKGROUND AND AIMS

IDegAsp (Ryzodeg 70/30), a unique premixed formulation of long-acting insulin degludec and rapid-acting insulin aspart, is increasing in use. Management of IDegAsp during hospitalisation is challenging because of degludec's ultra-long duration of action. We investigated inpatient glycaemia in patients treated with IDegAsp compared to biphasic insulin aspart (BIAsp30; Novomix30).

METHODS

We performed a retrospective observational study at two hospitals assessing inpatients with type 2 diabetes treated with IDegAsp or BIAsp30 prior to and during hospital admission. Standard inpatient glycaemic outcomes were analysed based on capillary blood glucose (BG) measurements.

RESULTS

We assessed 88 individuals treated with IDegAsp and 88 HbA1c-matched individuals treated with BIAsp30. Patient characteristics, including insulin dose at admission, were well matched, but the IDegAsp group had less frequent twice-daily insulin dosing than the BIAsp30 group (49% vs 87%, P < 0.001). Patient-days with BG <4 mmol/L were not different (10.6% vs 9.9%, P = 0.7); however, the IDegAsp group had a higher patient-day mean BG (10.4 (SD 3.4) vs 10.0 (3.4) mmol/L, P < 0.001), and more patient-days with mean BG >10 mmol/L (48% vs 38%, P < 0.001) compared to the BIAsp30 group. Glucose was higher in the IDegAsp group in the evening (4 PM to midnight) (11.6 (SD 4.0) vs 10.9 (4.6) mmol/L, P = 0.004), but not different at other times during the day.

CONCLUSIONS

Inpatients treated with IDegAsp compared to BIAsp30 had similar hypoglycaemia incidence, but higher hyperglycaemia incidence, potentially related to less frequent twice-daily dosing. With the increasing use of IDegAsp in the community, development of hospital management guidelines for this insulin formulation is needed.

The Short-Term Cost-Effectiveness of a Fixed-Ratio Combination of Insulin Degludec and Aspart: A Cost of Control Analysis in Australia and India

OBJECTIVES

The real-world ARISE study demonstrated initiation of fixed-ratio combination insulin degludec and aspart (IDegAsp) led to improvements in people achieving key glycemic control targets compared with prior therapies in Australia and India. This study evaluated the short-term cost-effectiveness of IDegAsp in these countries, in terms of the cost per patient achieving these targets.

METHODS

A model was developed to evaluate the cost of control (treatment costs divided by the proportion of patients achieving each target) of IDegAsp versus prior therapies received in ARISE for 2 endpoints: glycated hemoglobin (HbA1c) <7.0%, and HbA1c less than a predefined individual treatment target. Costs, expressed from a healthcare payer perspective, were captured in 2022 Australian dollars (AUD) and 2022 Indian rupees (INR).

RESULTS

The number of patients needed to treat to bring one to endpoints of HbA1c <7.0% and less than an individualized target with IDegAsp was 51% and 87% lower, respectively, than with prior therapies in Australia, and 52% and 66% lower, respectively, versus prior therapies in India. Cost of control was AUD 2449 higher and AUD 64 863 lower with IDegAsp versus prior therapies for endpoints of HbA1c <7.0% and less than an individualized target, respectively, in Australia and INR 211 142 and INR 537 490 lower with IDegAsp compared with prior therapies in India.

CONCLUSIONS

IDegAsp was estimated to be cost-effective versus prior therapies when considering an individualized HbA1c target in Australia, and when considering an individualized HbA1c target and HbA1c <7.0% in India.
