Is it reasonable to use a lower DOACs dose in some patients with VTE? Yes

Abstract

In the Hokusai-VTE trial, 733 patients were treated with the reduced dose edoxaban regimen, which maintained efficacy and safety compared with the 60mg dose, and was safer than warfarin. The prophylactic doses of apixaban and rivaroxaban reduced the risk of recurrent venous thromboembolism (VTE) in the extended treatment trials. Dabigatran 110mg was approved by the European Medicine Agency for VTE treatment. Further data from registries and real-world studies will help to clarify whether patients, with other specific characteristics, can benefit from the reduced dose of direct oral anticoagulants.
