New two-year Follow-up Data From ETNA-AF-Europe Reaffirms Benefit of LIXIANA® (Edoxaban) in People With Atrial Fibrillation

• Large routine clinical practice study, ETNA-AF-Europe, demonstrates continued benefits of edoxaban across age groups and supports treatment in elderly patient populations, in line with those observed in ETNA-AF after one year and in ENGAGE AF-TIMI 48

• ETNA-AF-Europe is part of the global ETNA-AF programme, which is the largest prospective, non-interventional study investigating a single non-vitamin K antagonist oral anticoagulant (NOAC) to date

• Data presented at the annual scientific meeting of the European Heart Rhythm Association

Daiichi Sankyo Europe announced the presentation of new routine clinical practice outcomes data confirming, in line with the randomized clinical trial data, the consistent effectiveness and safety profile of LIXIANA^® (edoxaban) in protecting against the risk of stroke in people with atrial fibrillation (AF). Over 13,000 patients were followed for two years in the ETNA-AF-Europe study, showing stroke and bleeding rates in line with rates seen after one year of follow-up. The data were presented at the annual scientific meeting of the European Heart Rhythm Association (EHRA 2021).¹

“AF is a long-term condition which puts people at an increased risk of stroke, so it is very important that we have treatments that can provide benefits over the long term,” said Joris R. de Groot, MD, PhD, FESC, Professor of Cardiac Electrophysiology and Atrial Fibrillation at University of Amsterdam; Cardiologist at the Amsterdam University Medical Centers, Amsterdam the Netherlands. “We are seeing that more frail patients receiving the lower dose of edoxaban are not at increased risk of intracranial hemorrhage and are benefitting from treatment. This underlines the importance of prescribing anticoagulant therapy even for aging AF patients.”

Event rates for stroke and death were 0.69% and 3.80% per year, respectively. Some patients were prescribed the lower dose of edoxaban (30 mg) for reasons including renal impairment. Annual event rates of intracranial hemorrhage were similar for both 60 mg (0.2%) and 30 mg (0.22%) doses. As a study investigating treatment in routine clinical practice, the data show that the majority of patients were using the recommended dose (83%).

The two-year outcome data in 13,417 patients across 10 European countries were from the European ETNA-AF (Edoxaban Treatment in routiNe clinical prActice in patients with nonvalvular Atrial Fibrillation) program, a non-interventional safety study evaluating edoxaban treatment in routine clinical practice for AF. ETNA-AF-Europe is part of the global ETNA-AF program, which is the largest prospective, non-interventional study program investigating a single non-vitamin K antagonist oral anticoagulant (NOAC) in patients with non-valvular atrial fibrillation (NVAF) to date.

Additional data in 27,617 people with AF from the global ETNA-AF program were also presented at EHRA 2021, confirming that the stroke and bleeding rates under use of edoxaban at two years were also considered low and in line with randomized clinical trials in this larger, global data set. Patients with AF benefitted from edoxaban treatment across age groups, including the very elderly (≥85 years), in routine clinical care.^2,3

“These data underline the importance of providing effective treatment for elderly and frail AF patients, who are already at higher risk of strokes and, as confirmed by these real-world data, benefit from edoxaban treatment,” said Dr. Garth Virgin, Executive Director Medical Affairs Specialty Medicines at Daiichi Sankyo Europe. “The ETNA-AF program is a huge undertaking that is providing critical insights into patient outcomes in routine clinical practice, and we are truly grateful for all the healthcare professionals and patients who are helping to make it possible.”
