Superior efficacy of insulin degludec/liraglutide versus insulin glargine U100 as add-on to sodium-glucose co-transporter-2 inhibitor therapy: A randomized clinical trial in people with uncontrolled type 2 diabetes.

ABSTRACT: AIM:To investigate the efficacy and safety of insulin degludec/liraglutide (IDegLira) versus insulin glargine 100?units/mL (IGlar U100) as add-on to sodium-glucose co-transporter-2 (SGLT2) inhibitor therapy. MATERIALS AND METHODS:In this 26-week, phase IIIb, open-label, parallel-group, treat-to-target trial, conducted at 74 sites in 11 countries, insulin-naïve people aged ?18?years with glycated haemoglobin (HbA1c) 53-97 mmol/mol (7.0-11.0%), body mass index 20-40?kg/m2 and inadequately controlled type 2 diabetes (T2D) on SGLT2 inhibitor ± oral antidiabetic drugs were randomized 1:1 to once-daily IDegLira or IGlar U100, both as add-on to existing therapy. The primary endpoint was change in HbA1c from baseline to week 26. RESULTS:A total of 210 participants were randomized to each treatment arm. Mean HbA1c reductions were 21 mmol/mol (1.9%-points) with IDegLira and 18 mmol/mol (1.7%-points) with IGlar U100; confirming non-inferiority (P?

Project description:BackgroundUnderstanding which therapeutic innovations in diabetes represent the best value requires rigorous economic evaluation. Data from randomised controlled trials and observational studies indicate that insulin degludec has a hypoglycemia advantage versus insulin glargine 100 units/mL (glargine U100), the most widely prescribed basal insulin analogue in the UK. This analysis was done to more rigorously assess cost-effectiveness in a UK setting.MethodsData from two double-blinded, randomised, two-period crossover trials in type 1 (SWITCH 1) and type 2 (SWITCH 2) diabetes mellitus were used to assess the cost-effectiveness of degludec vs. glargine U100 with an economic model. Cost-effectiveness was analysed over a 1-year time horizon based on the different rates of hypoglycaemia and actual doses of insulin used, rather than glycaemic control due to the treat-to-target trial design.ResultsIn type 1 diabetes mellitus, degludec was highly cost-effective compared with glargine U100, with an incremental cost-effectiveness ratio of £984 (increased costs of only £23/year and improvement in participant health of 0.0232 quality-adjusted life-years (QALYs)). In type 2 diabetes mellitus, it was estimated that quality of life was improved (0.0065 QALYs gain) with degludec compared with glargine U100 at an increased annual cost of £117 (incremental cost-effectiveness ratio, £17,939). One-way sensitivity analyses showed that the results were robust to changes in parameters in both type 1 and type 2 diabetes mellitus.ConclusionsThe rigorous design of the SWITCH trials, coupled with a representative patient population and a definition of hypoglycaemia that is relevant for real-world patients, makes the results of these trials highly generalisable. The within-trial analysis has the added value of being able to include doses and event rates directly from the trials. This short-term economic analysis estimated that IDeg would be cost-effective relative to IGlar U100 in both type 1 and type 2 diabetes mellitus in the UK.Trial registrationSWITCH 1 (NCT02034513); SWITCH 2 (NCT02030600).FundingNovo Nordisk, Søborg, Denmark.

Project description:ImportanceHypoglycemia, a serious risk for insulin-treated patients with type 2 diabetes, negatively affects glycemic control.ObjectiveTo test whether treatment with basal insulin degludec is associated with a lower rate of hypoglycemia compared with insulin glargine U100 in patients with type 2 diabetes.Design, setting, and participantsRandomized, double-blind, treat-to-target crossover trial including two 32-week treatment periods, each with a 16-week titration period and a 16-week maintenance period. The trial was conducted at 152 US centers between January 2014 and December 2015 in 721 adults with type 2 diabetes and at least 1 hypoglycemia risk factor who were previously treated with basal insulin with or without oral antidiabetic drugs.InterventionsPatients were randomized 1:1 to receive once-daily insulin degludec followed by insulin glargine U100 (n = 361) or to receive insulin glargine U100 followed by insulin degludec (n = 360) and randomized 1:1 to morning or evening dosing within each treatment sequence.Main outcomes and measuresThe primary end point was the rate of overall symptomatic hypoglycemic episodes (severe or blood glucose confirmed [<56 mg/dL]) during the maintenance period. Secondary end points were the rate of nocturnal symptomatic hypoglycemic episodes (severe or blood glucose confirmed, occurring between 12:01 am and 5:59 am) and the proportion of patients with severe hypoglycemia during the maintenance period.ResultsOf the 721 patients randomized (mean [SD] age, 61.4 [10.5] years; 53.1% male), 580 (80.4%) completed the trial. During the maintenance period, the rates of overall symptomatic hypoglycemia for insulin degludec vs insulin glargine U100 were 185.6 vs 265.4 episodes per 100 patient-years of exposure (PYE) (rate ratio = 0.70 [95% CI, 0.61-0.80]; P < .001; difference, -23.66 episodes/100 PYE [95% CI, -33.98 to -13.33]), and the proportions of patients with hypoglycemic episodes were 22.5% vs 31.6% (difference, -9.1% [95% CI, -13.1% to -5.0%]). The rates of nocturnal symptomatic hypoglycemia with insulin degludec vs insulin glargine U100 were 55.2 vs 93.6 episodes/100 PYE (rate ratio = 0.58 [95% CI, 0.46-0.74]; P < .001; difference, -7.41 episodes/100 PYE [95% CI, -11.98 to -2.85]), and the proportions of patients with hypoglycemic episodes were 9.7% vs 14.7% (difference, -5.1% [95% CI, -8.1% to -2.0%]). The proportions of patients experiencing severe hypoglycemia during the maintenance period were 1.6% (95% CI, 0.6%-2.7%) for insulin degludec vs 2.4% (95% CI, 1.1%-3.7%) for insulin glargine U100 (McNemar P = .35; risk difference, -0.8% [95% CI, -2.2% to 0.5%]). Statistically significant reductions in overall and nocturnal symptomatic hypoglycemia for insulin degludec vs insulin glargine U100 were also seen for the full treatment period.Conclusions and relevanceAmong patients with type 2 diabetes treated with insulin and with at least 1 hypoglycemia risk factor, 32 weeks' treatment with insulin degludec vs insulin glargine U100 resulted in a reduced rate of overall symptomatic hypoglycemia.Trial registrationclinicaltrials.gov Identifier: NCT02030600.

Project description:ImportanceHypoglycemia, common in patients with type 1 diabetes, is a major barrier to achieving good glycemic control. Severe hypoglycemia can lead to coma or death.ObjectiveTo determine whether insulin degludec is noninferior or superior to insulin glargine U100 in reducing the rate of symptomatic hypoglycemic episodes.Design, setting, and participantsDouble-blind, randomized, crossover noninferiority trial involving 501 adults with at least 1 hypoglycemia risk factor treated at 84 US and 6 Polish centers (January 2014-January 12, 2016) for two 32-week treatment periods, each with a 16-week titration and a 16-week maintenance period.InterventionsPatients were randomized 1:1 to receive once-daily insulin degludec followed by insulin glargine U100 (n = 249) or to receive insulin glargine U100 followed by insulin degludec (n = 252) and randomized 1:1 to morning or evening dosing within each treatment sequence.Main outcomes and measuresThe primary end point was the rate of overall severe or blood glucose-confirmed (<56 mg/dL) symptomatic hypoglycemic episodes during the maintenance period. Secondary end points included the rate of nocturnal symptomatic hypoglycemic episodes and proportion of patients with severe hypoglycemia during the maintenance period. The noninferiority criterion for the primary end point and for the secondary end point of nocturnal hypoglycemia was defined as an upper limit of the 2-sided 95% CI for a rate ratio of 1.10 or lower; if noninferiority was established, 2-sided statistical testing for superiority was conducted.ResultsOf the 501 patients randomized (mean age, 45.9 years; 53.7% men), 395 (78.8%) completed the trial. During the maintenance period, the rates of overall symptomatic hypoglycemia were 2200.9 episodes per 100 person-years' exposure (PYE) in the insulin degludec group vs 2462.7 episodes per 100 PYE in the insulin glargine U100 group for a rate ratio (RR) of 0.89 (95% CI, 0.85-0.94; P < .001 for noninferiority; P < .001 for superiority; rate difference, -130.31 episodes per 100 PYE; 95% CI, -193.5 to -67.16). The rates of nocturnal symptomatic hypoglycemia were 277.1 per 100 PYE in the insulin degludec group vs 428.6 episodes per 100 PYE in the insulin glargine U100 group, for an RR of 0.64 (95% CI, 0.56-0.73; P < .001 for noninferiority; P < .001 for superiority; rate difference, -61.94 episodes per 100 PYE; 95% CI, -83.85 to -40.03). A lower proportion of patients in the insulin degludec than in the insulin glargine U100 group experienced severe hypoglycemia during the maintenance period (10.3%, 95% CI, 7.3%-13.3% vs 17.1%, 95% CI, 13.4%-20.8%, respectively; McNemar P = .002; risk difference, -6.8%; 95% CI, -10.8% to -2.7%).Conclusions and relevanceAmong patients with type 1 diabetes and at least 1 risk factor for hypoglycemia, 32 weeks' treatment with insulin degludec vs insulin glargine U100 resulted in a reduced rate of overall symptomatic hypoglycemic episodes.Trial registrationclinicaltrials.gov Identifier: NCT02034513.
