Cost-Effectiveness of iGlarLixi in People with Type 2 Diabetes Mellitus Suboptimally Controlled on Basal Insulin Plus Metformin in the UK.

ABSTRACT:

Introduction

A cost-effectiveness analysis was conducted comparing a fixed-ratio combination (FRC) of insulin glargine 100 units/mL plus lixisenatide (iGlarLixi) versus the FRC of insulin degludec plus liraglutide (iDegLira) and the free-combination comparators insulin glargine plus dulaglutide (iGlar plus Dula) and basal insulin plus liraglutide (BI plus Lira).

Methods

The IQVIA Core Diabetes Model was used to estimate lifetime costs and outcomes for a cohort of patients with type 2 diabetes mellitus (T2DM) from the UK healthcare perspective. Initial clinical data for iGlarLixi were based on the randomized, controlled LixiLan-L trial and the relative treatment effects for comparators were based on an indirect treatment comparison using data from the AWARD-9 (iGlar plus Dula), LIRA ADD2 BASAL (BI plus Lira), and DUAL V (iDegLira) trials. Costs were derived from publicly available sources. Lifetime costs (in British Pound Sterling [£]) and quality-adjusted life-years (QALYs) were predicted; net monetary benefit (NMB) for iGlarLixi versus comparators was derived using a willingness-to-pay threshold of £20,000. Extensive scenario and sensitivity analyses were conducted.

Results

Estimated costs were lowest with iGlarLixi (£31,295) compared with iGlar plus Dula (£38,790), iDegLira (£40,179), and BI plus Lira (£42,467). Total QALYs gained were identical with iGlarLixi and iDegLira (8.438), and comparable with iGlar plus Dula (8.439) and BI plus Lira (8.466). NMB for iGlarLixi was positive versus all comparators (£10,603.86 vs. BI plus Lira; £7,466.24 vs. iGlar plus Dula; £8.874.11 vs. iDegLira).

Conclusion

In patients with T2DM with suboptimal glycemic control on basal insulin, iGlarLixi provides very similar outcomes and substantial cost savings, compared with other fixed and free combinations of insulins plus glucagon-like peptide-1 receptor agonists.

Project description:IntroductionFew patients with type 2 diabetes mellitus (T2DM) achieve recommended glycemic control targets in the Czech Republic. Novel therapies, such as fixed-ratio combinations of basal insulin plus glucagon-like peptide-1 receptor agonists, may contribute to better glycemic control. In the analysis presented here, the present analysis assessed the long-term cost-effectiveness of two fixed-ratio combinations, IDegLira (insulin degludec/liraglutide) and iGlarLixi (insulin glargine/lixisenatide), for the treatment of patients with T2DM inadequately controlled with basal insulin from a healthcare payer perspective in the Czech Republic.MethodsA cost-effectiveness analysis was performed over patient lifetimes using the IQVIA CORE Diabetes Model. Treatment effects were obtained from an indirect treatment comparison as no head-to-head data for IDegLira versus iGlarLixi are currently available. IDegLira was compared with two iGlarLixi pens (100 U/mL insulin glargine + 33 μg/mL and 50 μg/mL of lixisenatide, respectively). Direct medical costs associated with pharmaceutical interventions, screening and diabetes-related complications were captured. Deterministic and probabilistic sensitivity analyses were performed.ResultsIDegLira was associated with gains in life expectancy of 0.11 years and in quality-adjusted life expectancy of 0.14 quality-adjusted life-years (QALYs) versus iGlarLixi, due to a lower cumulative incidence and delayed onset of diabetes-related complications. IDegLira was also associated with higher projected costs due to higher acquisition costs; however, these were partially offset by cost savings from avoided complications. IDegLira was associated with incremental cost-effectiveness ratios of Czech Koruna (CZK) 695,998 and CZK 348,323 per QALY gained versus iGlarLixi pens containing 33 and 50 μg/mL of lixisenatide, respectively. These ratios were below the commonly used willingness-to-pay threshold of CZK 1,200,000 per QALY gained.ConclusionThe present analysis indicated that IDegLira was associated with clinical benefits relative to iGlarLixi over patient lifetimes and was likely to be cost-effective in the treatment of patients with T2DM uncontrolled on basal insulin in the Czech Republic.FundingNovo Nordisk.

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.
