AstraZeneca’s Farxiga (dapagliflozin) has been approved in the US to reduce the risk of cardiovascular (CV) death, hospitalisation for heart failure (hHF) and urgent heart failure (HF) visits in adults with HF.
The approval by the Food and Drug Administration (FDA) was based on positive results from the DELIVER Phase III trial. Farxiga was previously approved in the US for adults with HF with reduced ejection fraction (HFrEF).
Ruud Dobber, Executive Vice-President, BioPharmaceuticals Business Unit, AstraZeneca, said: “Approximately half of heart failure patients die within five years of diagnosis, highlighting an urgent unmet need for well-tolerated treatment options that can bring life-saving benefits and reduce the risk of cardiovascular death. The approval of Farxiga in the US not only reinforces AstraZeneca’s commitment to reducing the burden of this complex and life-threatening disease, but will help patients across the full spectrum of heart failure lead healthier lives.”
HF is a chronic, long-term condition that worsens over time and affects almost seven million people in the US. It is also the leading cause of hospitalisation for those over 65 years and represents a significant clinical and economic burden. Approximately half of all HF patients have HF with mildly reduced ejection fraction (HFmrEF) or HF with preserved ejection fraction (HFpEF) and these patients are not only at greater risk of death and hospitalisations but experience an especially high burden of symptoms and physical limitations, and a poor quality of life.

The data from the DELIVER Phase III trial, published in The New England Journal of Medicine, showed Farxiga reached a statistically significant and clinically meaningful early reduction in the primary composite endpoint of CV death or worsening HF in patients with HF with HFmrEF or HFpE.F1 The results from a pre-specified, pooled analysis of the DAPA-HF and DELIVER Phase III trials, published in Nature Medicine, showed that the treatment effect of Farxiga on the composite endpoint of cardiovascular death, hospitalisation for heart failure or urgent heart failure was consistent across the left ventricular ejection fraction (LVEF) range and established Farxiga as the first sodium-glucose cotransporter 2 (SGLT2) inhibitor to demonstrate a mortality benefit.7
Farxiga is approved for the treatment of patients with type-2 diabetes (T2D), HFrEF and chronic kidney disease (CKD) in more than 100 countries around the world including the US, the European Union (EU), China and Japan. It has most recently received regulatory approvals in the EU, Great Britain, Japan and Turkey to extend the HF indication to include patients across the full LVEF range.
HF is a chronic, long-term condition that worsens over time. It affects nearly 64 million people globally8 and is associated with substantial morbidity and mortality. Chronic HF is the leading cause of hospitalisation for those over the age of 65 and represents a significant clinical and economic burden. There are several types of HF often defined by LVEF, a measurement of the percentage of blood leaving the heart each time it contracts, including: HFrEF (LVEF less than or equal to 40%), HFmrEF (LVEF 41-49%) and HFpEF (LVEF greater than or equal to 50%). Approximately half of all HF patients have HFmrEF or HFpEF, with few therapeutic options available.
DELIVER was an international, randomised, double-blind, parallel-group, placebo-controlled, event-driven Phase III trial designed to evaluate the efficacy of Farxiga, compared with placebo, in the treatment of HF patients with LVEF greater than 40%, with or without T2D. Farxiga was given once daily in addition to background therapy (regional SoC for all comorbidities, including diabetes and hypertension, with the exception of concomitant use of a sodium-glucose cotransporter 2 (SGLT2) inhibitor). DELIVER is the largest clinical trial to date in HF patients with LVEF above 40%, with 6,263 randomised patients.
The primary composite endpoint was the time to first occurrence of CV death, hHF or an urgent HF visit. Key secondary endpoints include the total number of HF events (hHF or urgent HF visit) and CV death, change from baseline in the total symptom score of the KCCQ at eight months, time to the occurrence of CV death and time to the occurrence of death from any cause.
Farxiga (dapagliflozin) is a first-in-class, oral, once-daily SGLT2 inhibitor. Research has shown Farxiga’s efficacy in preventing and delaying cardiorenal disease, while also protecting the organs – important findings given the underlying links between the heart, kidneys and pancreas.12-14 Damage to one of these organs can cause the other organs to fail, contributing to leading causes of death worldwide, including T2D, HF and CKD.
Cardiovascular, Renal and Metabolism (CVRM), part of BioPharmaceuticals, forms one of AstraZeneca’s main disease areas and is a key growth driver for the Company. By following the science to understand more clearly the underlying links between the heart, kidneys and pancreas, AstraZeneca is investing in a portfolio of medicines for organ protection and improving outcomes by slowing disease progression, reducing risks and tackling co-morbidities. The Company’s ambition is to modify or halt the natural course of CVRM diseases and potentially regenerate organs and restore function, by continuing to deliver transformative science that improves treatment practices and CV health for millions of patients worldwide.
