Safety and Effectiveness of Low Dose Edoxaban in Patients With NVAF

Atrial Fibrillation

safety, effectiveness, low dose

The efficacy and safety of edoxaban has not been adequately studied in Asians versus non-Asians, who are quite different physiologically from each other. Compared with non-East Asian patients, the East Asia patients were twice as likely to have the reasons for requiring dose reduction of edoxaban, such as CrCl 30-50 ml/min (30.0% and 18.2%, respectively), weight ≤60 kg (30.6% and 7.8%, respectively), or concomitant use of verapamil or quinidine (P-gp inhibitors, 6.6% and 3.3%, respectively). This study is aimed to evaluate the safety of the low dose edoxaban therapy in patients with high bleeding risk and non-valvular AF in the real world population of Korea.

The efficacy and safety of edoxaban has not been adequately studied in Asians versus non-Asians, who are quite different physiologically from each other. Although 1,943 patients from East Asia (1,010 were from Japan, 469 from China, 234 from Taiwan, and 230 from South Korea) were included in ENGAGE AF-TIMI 48, majority of the patient (19,162) were from non-East Asia. Compared with non-East Asian patients, the East Asia patients were twice as likely to have the reasons for requiring dose reduction of edoxaban, such as CrCl 30-50 ml/min (30.0% and 18.2%, respectively), weight ≤60 kg (30.6% and 7.8%, respectively), or concomitant use of verapamil or quinidine (P-gp inhibitors, 6.6% and 3.3%, respectively). Due to the relatively small number of patients in the East Asian group included in the analysis compared with that of the patients in the non-East Asian group, a limitation preventing it from providing sufficient power for such comparison is unavoidable. This study is aimed to evaluate the safety of the low dose edoxaban therapy in patients with high bleeding risk and non-valvular AF in the real world population of Korea.
