Abstract

Aims: Liraglutide has been shown to reduce cardiovascular mortality in a cardiovascular safety study, but it is not known to what extent these results will be replicated in real practice with people with diabetes treated with liraglutide in the UK. We wished to explore the likely cardiovascular benefits by modelling 10-year reduction in cardiovascular events and mortality using data from the ABCD liraglutide audit database.

Methods: The UKPDS risk engine 2.0 was applied to data collected in the ABCD liraglutide audit database before and at the earliest return to clinic between 3 and 9 months after commencing liraglutide, using the 747 of 6,959 records where all factors used by the risk engine were completely recorded.

Results: There were significant falls in all factors used in the UKPDS cardiovascular disease (CVD) risk assessment other than HDL cholesterol which was unchanged. The UKPDS risk engine mean±SD 10-year coronary heart disease (CHD) risk fell by 2.7±7.6% from 18.7±13.0% to 16.1±11.6% (p<0.001). The 10-year fatal CHD risk fell by 2.3±6.5% from 13.7±11.1% to 11.4±9.8% (p<0.001). The 10-year stroke risk fell by 0.3±2.8% from 7.9±8.7% to 7.6±8.3% (p=0.003). The 10-year fatal stroke risk fell by 0.1±0.7% from 1.2±1.4% to 1.1±1.3% (p=0.001).

Conclusion: Starting liraglutide reduced 10-year CVD risk. These data suggest that liraglutide used in routine clinical care in 100 patients could prevent three events of CHD or stroke and save two or more lives over the next 10 years.

Introduction

Liraglutide has been shown to reduce cardiovascular outcomes in patients at high risk of cardiovascular disease (CVD).1 Uncertainty exists regarding the impact of liraglutide on CVD risk in routine clinical care. The United Kingdom Prospective Diabetes Study (UKPDS) CVD risk engine version 2.02 uses recognised risk factors to calculate future CVD risk. Our aim was to establish the predicted impact of liraglutide in routine use in the UK on 10-year CVD risk.

Methods

We used data from the Association of British Clinical Diabetologists (ABCD) nationwide liraglutide audit,3 which assesses liraglutide in routine clinical practice. The audit database comprises data on 6,959 patients from 163 centres in the UK between 2009 and 2017. The daily dose of liraglutide prescribed was 1.2 mg (84%), 0.6 mg (9%) and 1.8 mg (6%). For this analysis we included all patients with all the factors used by the risk engine (age, duration of diabetes, ethnicity, systolic blood pressure, HbA1c, total cholesterol and HDL cholesterol) measured before and at the earliest return to clinic between 3 and 9 months after commencing liraglutide. As we did not have data on atrial fibrillation, smoking or previous CVD, these were assumed to be absent for the purposes of the analysis.

Results

Table 1 shows the baseline characteristics of those 747 patients with complete datasets and the early impact of liraglutide treatment on CVD risk factors. The reasons for incomplete datasets include the fact that the data did not exist (unavoidable in an observational clinical audit of this nature or not input by contributors). The liraglutide database holds no demographic or social data.

There were statistically significant falls in all factors used in the UKPDS CVD risk assessment other than HDL cholesterol which was unchanged. The UKPDS risk engine mean±SD 10-year coronary heart disease (CHD) risk fell by 2.7±7.6% from 18.7±13.0% to 16.1±11.6% (p<0.001) and the 10-year fatal CHD risk fell by 2.3±6.5% from 13.7±11.1% to 11.4±9.8% (p<0.001). The 10-year stroke risk fell by 0.3±2.8% from 7.9±8.7% to 7.6±8.3% (p=0.003) and the 10-year fatal stroke risk fell by 0.1±0.7% from 1.2±1.4% to 1.1±1.3% (p=0.001).

Starting liraglutide in our study therefore reduced the 10-year cardiovascular event risk by 3.0% (2.7%+0.3%) and the 10-year cardiovascular death risk by 2.4% (2.3%+0.1%). The number needed to treat to prevent one cardiovascular event over 10 years was 33 and to prevent one death over 10 years was 42.

Weight, which is not a factor used in the UKPDS risk engine, was assessed in the 3,535 patients in the audit with weight and body mass index (BMI) data during the same time interval. Weight fell by 2.8±6.1 kg from 110.0±22.3 kg to 107.9±22.1 kg (p<0.001) and BMI by 0.98±2.2 kg/m2 from 38.7±7.0 kg/m2 to 37.8±6.9 kg/m2 (p<0.001).

Discussion

The Leader study has shown that the rate of the first occurrence of death from cardiovascular causes, non-fatal myocardial infarction or non-fatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo. Over the median of 3.8 years of follow-up there were significantly fewer cardiovascular deaths in patients treated with liraglutide (4.7%) compared with placebo (6.0%). If this difference in cardiovascular deaths is extrapolated to 10 years, then the estimated difference in the number of cardiovascular deaths is 3.4%.

The Leader study entrance criteria required the presence of high cardiovascular risk: 81.3% had prior CVD and 18.7% had a high risk but without prior CVD.4 In comparison, in this modelling study based on the ABCD liraglutide audit database, although many of the population had high cardiovascular risk, the population was selected only because a clinician had decided that someone with diabetes was likely to benefit from liraglutide; we do not know what proportion of patients in the audit had previous CVD but if – as is likely – a greater proportion than in the Leader study did not have established CVD, then a lower level of risk reduction would be expected. Starting liraglutide in our study reduced 10-year cardiovascular event risk by 3.0% and 10-year cardiovascular death risk by 2.4%. The number needed to treat to prevent one cardiovascular event over 10 years was 33 and to prevent one death over 10 years was 42. For statins, a meta-analysis of studies performed before 1999 indicated that the number needed to treat to prevent one cardiovascular death over 5 years was 20.5 Unlike statins, however, the benefits of liraglutide are not confined to reducing cardiovascular risk.

The importance of collecting real-world audit data is illustrated by the difference in the populations of people with diabetes treated in the UK compared with the population studied within the Leader study. The mean BMI of people with diabetes in the ABCD liraglutide audit was 38.7 kg/m2 compared with a mean BMI of 32.5 kg/m2 in the Leader study. Obesity is an independent risk factor for CHD events.6,7 BMI is not included on the UKPDS risk engine so, arguably, the cardiovascular benefits found in this study might be an underestimate.

As this study used the earliest assessment after commencement of liraglutide, it is possible that the impact would be greater with longer follow-up. However, it is also possible that, in some patients, the initial reductions in risk factors would not be maintained so the benefits would be less.

Considering changes in single cardiovascular risk factors, for systolic blood pressure there was a significant mean fall of 3.5 mmHg in the 747 people whose data were used in the analysis. This is comparable to a fall in systolic blood pressure of 3.18 mmHg found in a meta-analysis of 18 randomised controlled trials;8 however, in the meta-analysis the difference was no longer significant when liraglutide treatment continued beyond one year.

With respect to lipids, there was a 0.25 mmol/L fall in total cholesterol levels but no significant change in HDL levels. These findings are similar to those reported in a meta-analysis in 20159 and two subsequent studies.10,11

For HbA1c, the fall of 9.8 mmol/mmol (0.9%) is comparable to that seen in those phase 3 studies which included the 1.2 mg daily dose of liraglutide,12-15 which reported HbA1c falls of 1.1%, 1.0%, 0.8% and 1.5%, respectively.

A limitation of the study is the absence of data on smoking, atrial fibrillation and previous CVD in the liraglutide audit database. These limitations reflect the nature of real-world audit in that the dataset in the audit questionnaire used by participating centres was necessarily kept to a minimum to facilitate collection by busy clinicians. Another limitation is that the calculation depends upon maintenance of the observed changes in the components of the risk engine over 10 years. In addition, no modelling technique is perfect, and since the creation of the UKPDS risk engine there have been changes in diets, smoking, use of statins, use and types of antihypertensive agents, treatments for diabetes, alcohol consumption and pollution levels which might affect the validity of the tool when applied to recently collected data, and the calculations may not be generalisable to populations outside the UK. For the UK population, however, the UKPDS engine remains the best available tool to estimate the benefit likely to accrue in terms of reduced numbers of cardiovascular events and death.

We are also aware that there is a possibility of bias in that the 747 patients whose data were complete for all six items required for the UKPDS risk engine were a subset of the total of 6,959 patients. The datasets submitted by clinicians are also a subset of those patients treated by liraglutide within the UK, so we cannot exclude bias arising from factors such as less compliant patients being less likely to be included within this subset. Nevertheless, we believe this study provides a useful working basis for clinicians to discuss the magnitude of the cardiovascular risk benefit to people with diabetes treated with liraglutide in everyday practice within the UK.
