Landmark real-world evidence from an international study of more than 300,000 patients with type-2 diabetes showed treatment with SGLT-2 inhibitors reduced all-cause mortality by 51% and risk of hospitalisation for heart failure by 39%
AstraZeneca has announced results of the first large real-world evidence study of its kind evaluating the risk of hospitalisation for heart failure and death from any cause in patients with type-2 diabetes (T2D) receiving treatment with a newer class of diabetes medicines, SGLT-2 inhibitors (SGLT-2i).1
The CVD-REAL study assessed data from more than 300,000 patients across six countries, 87% of whom did not have a history of cardiovascular disease. The data showed that across this broad population of patients with T2D, treatment with SGLT-2i medicines – Farxiga (dapagliflozin), canagliflozin, empagliflozin – reduced the rate of hospitalisation for heart failure by 39% (p<0.001) and death from any cause by 51% (p<0.001), compared to other T2D medicines. For the composite endpoint of hospitalisation for heart failure and death from any cause, the reduction was 46% (p<0.001).
Worldwide, diabetes affects around 415 million adults, a number estimated to rise to 642 million by 2040 (1 in 10 adults). People with T2D have a 2-3 times greater risk of heart failure and are at an increased risk of having a heart attack or stroke, and some 50% of deaths in people with T2D are caused by cardiovascular disease.
Bruce Cooper, MD, Vice President and Head of Global Medical Affairs at AstraZeneca, said: “Diabetes is a growing epidemic worldwide, which is associated with significant comorbidities that contribute to an increased risk of costly hospitalisations and even death.6,7 Real-world data from this study provide striking evidence that the newer SGLT-2i class of medicines cuts the rate of hospitalisations for heart failure and death by approximately half. CVD-REAL is the first study to observe these effects of SGLT-2i treatment in a much broader and lower risk group of type-2 diabetes patients than previously evaluated in clinical trials.”
The hospitalisations for heart failure analysis was conducted using anonymised patient data from Denmark, Germany, Norway, Sweden, United Kingdom and the United States. Of the data reviewed, 41.8% of patients were on Farxiga (dapagliflozin), 52.7% on canagliflozin and 5.5% on empagliflozin. The analysis of death from any cause was conducted using anonymised patient data from Denmark, Norway, Sweden, United Kingdom and the United States. Of the data reviewed, 51.0% of patients were on Farxiga (dapagliflozin), 42.3% on canagliflozin and 6.7% on empagliflozin.
This is the first of several comparative analyses of CVD-REAL. The collection of real-word evidence is ongoing and future analyses will be conducted using this dataset as well as data from additional countries. All the data for the study were obtained from anonymised real-world sources including medical records, claims databases and national registers. The analysis was validated by the independent academic statistical group at St. Luke’s Mid America Heart Institute, Kansas City, US
