Diabetes-Related Effectiveness and Cost of Liraglutide or Insulin in German Patients with Type 2 Diabetes: A 5-Year Retrospective Claims Analysis.

ABSTRACT:

Introduction

Liraglutide is a glucagon-like peptide-1 analogue used to treat type 2 diabetes mellitus (T2DM). To date, limited long-term data (> 2 years) exist comparing real-world diabetes-related effectiveness and costs for liraglutide versus insulin treatment.

Methods

This retrospective claims data analysis covered the period from 1 January 2010 to 31 December 2017 and included continuously insured patients with T2DM who initiated insulin or liraglutide and had 3.5 or 5 years' follow-up data, identified using the German AOK PLUS dataset. Propensity score matching (PSM) was used to adjust for patient characteristics.

Results

After PSM, there were 825 and 436 patients in the liraglutide and insulin groups at 3.5 and 5 years' follow-up, respectively. Baseline characteristics were similar between compared cohorts. The respective change from baseline to follow-up in mean glycated haemoglobin for liraglutide and insulin patients was - 0.88% and - 0.81% (p > 0.100) after 3.5 years and - 1.15%/ - 1.02% (p > 0.100) after 5 years. Mean respective changes in body mass index (kg/m²) were - 1.21/+ 1.14 (p < 0.001) after 3.5 years and - 1.29/+ 1.13 after 5 years (p < 0.001). Liraglutide- versus insulin-treated patients were less likely to have an early T2DM-related hospitalisation (3.5-year hazard ratio [HR]: 0.414 [95% confidence interval (CI) 0.263-0.651]; 5-year HR: 0.448 [95% CI 0.286-0.701]). At 5 years' follow-up, there was no statistically significant difference in total direct costs between treatment groups (cost ratio: 1.069 [95% CI 0.98-1.13]; p > 0.100).

Conclusion

The clinical effectiveness of liraglutide is maintained long term (up to 5 years). Liraglutide treatment is not associated with higher total direct healthcare costs.

Project description:BackgroundWe assessed the cost-effectiveness of the glucagon-like peptide 1 receptor agonists liraglutide 1.8 mg and lixisenatide 20 μg (both added to basal insulin) in patients with type 2 diabetes (T2D) in Sweden.MethodsThe Swedish Institute for Health Economics cohort model for T2D was used to compare liraglutide and lixisenatide (both added to basal insulin), with a societal perspective and with comparative treatment effects derived by indirect treatment comparison (ITC). Drug prices were 2016 values, and all other costs 2015 values. The cost-effectiveness of IDegLira (fixed-ratio combination of insulin degludec and liraglutide) versus lixisenatide plus basal insulin was also assessed, under different sets of assumptions.ResultsFrom the ITC, decreases in HbA1c were -1.32% and -0.43% with liraglutide and lixisenatide, respectively; decreases in BMI were -1.29 and -0.65 kg/m2, respectively. An estimated 2348 cases of retinopathy, 265 of neuropathy and 991 of nephropathy would be avoided with liraglutide compared with lixisenatide in a cohort of 10,000 patients aged over 40 years. In the base-case analysis, total direct costs were higher with liraglutide than lixisenatide, but costs associated with complications were lower. The cost/quality-adjusted life-year (QALY) for liraglutide added to basal insulin was SEK30,802. Base-case findings were robust in sensitivity analyses, except when glycated haemoglobin (HbA1c) differences for liraglutide added to basal insulin were abolished, suggesting these benefits were driving the cost/QALY. With liraglutide 1.2 mg instead of liraglutide 1.8 mg (adjusted for efficacy and cost), liraglutide added to basal insulin was dominant over lixisenatide 20μg.IDegLira was dominant versus lixisenatide plus basal insulin when a defined daily dose was used in the model.ConclusionsThe costs/QALY for liraglutide, 1.8 or 1.2 mg, added to basal insulin, and for IDegLira (all compared with lixisenatide 20 μg added to basal insulin) were below the threshold considered low by Swedish authorities. In some scenarios, liraglutide and IDegLira were cost-saving.

Project description:ObjectivesMetformin is the first-line therapy for most patients with type 2 diabetes, but the majority require treatment intensification at some stage due to the progressive nature of the disease. The 1860-LIRA-DPP-4 trial showed that liraglutide exhibited greater improvements compared with sitagliptin in glycated hemoglobin and body mass index in patients with type 2 diabetes inadequately controlled on metformin monotherapy. As a follow-up to a previously published cost-effectiveness analysis of 1.2 mg liraglutide versus sitagliptin in Spain, the aim of this analysis was to compare long-term projections of the clinical and cost implications associated with 1.8 mg liraglutide and sitagliptin.MethodsFor the modeling analysis, 52-week treatment effect data (as opposed to 26-week data in the previous analysis) were taken from the 1860-LIRA-DPP-4 trial, for adults with type 2 diabetes receiving 1.8 mg liraglutide or 100 mg sitagliptin daily in addition to metformin. Long-term (patient lifetime) projections of clinical outcomes and direct costs (2012 EUR) were made using a published and validated model of type 2 diabetes, with modeling assumptions as per the 1.2 mg liraglutide analysis.ResultsLiraglutide was associated with increased life expectancy (14.24 versus 13.87 years) and quality-adjusted life expectancy [9.24 versus 8.84 quality-adjusted life years (QALYs)] over sitagliptin. Improved clinical outcomes were attributable to the improvement in glycemic control, leading to a reduced incidence of diabetes-related complications, including renal disease, cardiovascular disease, ophthalmic and diabetic foot complications. Liraglutide was associated with increased direct costs (EUR 56,628 versus EUR 52,450), driven by increased pharmacy costs. Based on these estimates, liraglutide was associated with an incremental cost-effectiveness ratio of EUR 10,436 per QALY gained versus sitagliptin.ConclusionsA previous analysis has suggested that 1.2 mg liraglutide is cost-effective from a healthcare payer perspective in Spain, and the present analysis suggests that the 1.8 mg dose is also likely to be cost-effective.
