Clinical benefits of switching to insulin degludec irrespective of previous basal insulin therapy in people with Type 1 or Type 2 diabetes: evidence from a European, multicentre, retrospective, non-interventional study (EU-TREAT).

ABSTRACT: AIMS:To investigate whether the benefits of switching to insulin degludec observed in the European retrospective chart review study EU-TREAT were dependent on the previous basal insulin used. METHODS:People with Type 1 or Type 2 diabetes were switched to insulin degludec from other basal insulins ?6 months before data collection. Participants were stratified into three groups based on their previous basal insulin: insulin glargine 100 units/ml (Type 1: n=888; Type 2: n=259); insulin detemir (Type 1: n=726; Type 2: n=415); and neutral protamine Hagedorn (Type 1: n=53; Type 2: n=95). Their glycaemic control and hypoglycaemia incidence at 6 and 12 months post-switch vs pre-switch was then evaluated. RESULTS:Significant HbA1c reductions were achieved in all previous basal insulin groups for participants with Type 1 diabetes [insulin glargine 100 units/ml: -2.08 mmol/mol (-0.19%); insulin detemir: -2.40 mmol/mol (-0.22%)] and those with Type 2 diabetes [insulin glargine 100 units/ml: -5.90 mmol/mol (-0.54%); insulin detemir: -6.01 mmol/mol (-0.55%); neutral protamine Hagedorn: -2.73 mmol/mol (-0.25%)] at 6 months, except for the relatively small neutral protamine Hagedorn group in those with Type 1 diabetes [-1.75 mmol/mol (-0.16%)], where statistical significance was not reached. At 6 months in the Type 1 diabetes group, switching to insulin degludec from insulin glargine 100 units/ml resulted in significantly lower hypoglycaemia rates across all hypoglycaemia categories; for the insulin detemir group, this significance was also observed for severe and nocturnal non-severe hypoglycaemia, while the low number of people in the neutral protamine Hagedorn group resulted in nonsignificant reductions in hypoglycaemia rates. At 6 months in the people with Type 2 diabetes, switching to insulin degludec resulted in significantly lower rates of hypoglycaemia across all categories for all groups. Similar outcomes were observed at 12 months. CONCLUSIONS:Switching to insulin degludec from other basal insulins can improve glycaemic control and/or reduce hypoglycaemia risk in people with diabetes (although there was a nonsignificant reduction in HbA1c and hypoglycaemia rates for the neutral protamine Hagedorn group in Type 1 diabetes) under routine care.

Project description:IntroductionInsulin degludec (degludec), an ultra-long-acting basal insulin analogue, provides equivalent glycemic control to other basal insulin analogues, with lower risk of hypoglycemia and flexible dosing. Chinese TREsiba AudiT (CN-TREAT) investigated outcomes with degludec in people with type 2 diabetes (T2D) in routine clinical practice in China.MethodsThis was a retrospective chart review study in adults with T2D initiating or switching to degludec at 50 sites in China between January 2020 and July 2021. The primary endpoint was change in glycated hemoglobin (HbA1c) from baseline to end of study (EOS; week 20). Secondary endpoints included change from baseline to EOS in fasting plasma glucose (FPG), self-measured plasma glucose (SMPG), daily insulin dose, and rate of hypoglycemia.ResultsData from 936 participants were included (499 insulin-naïve; 437 insulin-experienced). Mean (95% confidence interval [CI]) HbA1c change from baseline to EOS was - 1.48%-points (- 1.57; - 1.38; P < 0.0001) overall: - 1.95%-points (- 2.08; - 1.81; P < 0.0001) in insulin-naïve participants and - 0.95%-points (- 1.08; - 0.82; P < 0.0001) in insulin-experienced participants. Mean (95% CI) changes in FPG and SMPG were - 2.27 mmol/L (- 2.69; - 1.85; P < 0.0001) and - 2.89 mmol/L (- 3.52; - 2.25; P < 0.0001), respectively, with similar reductions in insulin-naïve and insulin-experienced subgroups. Rate of hypoglycemia did not change statistically significantly from baseline to EOS overall, or in insulin-experienced participants, except when adjusted for baseline hypoglycemia. Basal insulin dose did not change statistically significantly in insulin-experienced participants.ConclusionIn routine clinical practice in China, initiation or switching to degludec was associated with improvements in glycemic control in people with T2D, with no increased risk of hypoglycemia.Trial registrationClinialTrials.gov, NCT04227431.

Project description:IntroductionWith one of the fastest aging populations in the world, demographic changes in Japan are a major public health concern due to the substantial burden that aging-associated diseases, such as type 2 diabetes (T2D), place on public healthcare systems. The aim of this analysis was to evaluate the short-term cost-effectiveness of switching Japanese patients with T2D receiving basal-bolus insulin therapy from their previous basal insulin to insulin degludec (degludec) under conditions of routine clinical practice.MethodsA previously published, open-source model developed in Microsoft Excel was used to evaluate the cost-effectiveness of switching basal-bolus insulin therapy from patients' previous basal insulin to degludec versus continuing the previous basal insulin therapeutic regimen in terms of costs (2018 Japanese Yen [JPY]) and quality-adjusted life years (QALYs), from a Japanese public healthcare payer perspective. The model captured hypoglycemia rates and insulin dosing over a 1-year time horizon, and was informed by Japanese real-world evidence from the T2D cohort (N = 135) of the Kumamoto Insulin Degludec Observational study.ResultsTreatment with degludec was associated with improved effectiveness (+ 0.0354 QALYs), driven by lower daytime non-severe hypoglycemia rates with degludec, at slightly higher annual treatment costs (JPY 9510) versus continuing the previous basal insulin. Switching basal insulin to degludec was found to be a cost-effective intervention with an incremental cost-effectiveness ratio (JPY 268,811 per QALY gained) substantially below the willingness-to-pay threshold of 5 million JPY per QALY used in the Japanese Health Technology Assessment framework. Sensitivity analyses confirmed the robustness of this finding and indicated that the daytime non-severe hypoglycemia benefit with degludec was a key driver of outcomes in the base case.ConclusionBased on Japanese real-world evidence, our analysis suggests that switching Japanese patients with T2D receiving a basal-bolus regimen from their previous basal insulin to degludec would be highly cost-effective. These data may help decision-makers in Japan allocate healthcare resources efficiently.Trial registrationThe KIDUNA study is registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR): UMIN000021569.FundingNovo Nordisk Pharma Ltd.
