Trial design: A randomized, phase 3, double-blind, active-comparator, event-driven, superiority study comparing the efficacy and safety of once-daily XARELTO® at doses of 20 mg or 10 mg versus 100 mg of aspirin in patients with VTE who completed 6 to 12 months of treatment with VKA or a DOAC and were in equipoise regarding the need for extended anticoagulation. Study drugs were administered up to 12 months.
Because the benefit-risk assessment favored once-daily XARELTO® at the 10-mg dose versus aspirin (100 mg) compared with XARELTO® 20 mg once daily versus aspirin, the XARELTO® 10-mg dose is approved to reduce the risk of recurrent DVT/PE.
Primary outcomes: The primary efficacy outcome was symptomatic recurrent fatal or nonfatal VTE and the principal safety outcome was major bleeding.
*The decision regarding initiation setting should be based on the prescriber's clinical judgment.
DOAC = direct oral anticoagulant; DVT = deep vein thrombosis; PE = pulmonary embolism; VKA = vitamin K antagonist; VTE = venous thromboembolism.
