Abstract
Abstract Introduction The prospective, non-interventional XALIA study investigated the safety and effectiveness of rivaroxaban and standard anticoagulation for the treatment of deep vein thrombosis (DVT). XALIA-LEA was conducted in regions not included in XALIA (Latin America, Eastern Europe, the Middle East, Africa, and the Asia-Pacific), and enrolled patients with isolated pulmonary embolism (PE). Materials and methods Adult patients with acute venous thromboembolism (VTE) indicated for ≥3 months' anticoagulant treatment were eligible; treatment strategies were at the physician's discretion. Patients receiving rivaroxaban or standard anticoagulation (unfractionated or low-molecular weight heparin/fondaparinux alone or overlapping with and followed by a vitamin K antagonist [VKA]) were included in the safety analysis. "Early switchers" to rivaroxaban (i.e. after receiving heparin/fondaparinux for >2–14 days and/or a VKA for 1–14 days) were not included in the safety analysis set. Results Of the 1972 eligible patients, 1285 received rivaroxaban, 402 received standard anticoagulation, and 285 were early switchers. Most patients who received rivaroxaban were appropriately selected, received the correct dosing schedule, reported few adverse effects. Outcomes were similar to previously published results, with rivaroxaban associated with a low rate of major bleeding (1.6%), recurrent VTE (1.4%) and all-cause mortality (2.3%). Including early switchers, relatively fewer patients with index isolated PE received rivaroxaban (14.4%) versus standard anticoagulation therapy (20.9%). Some regional variations and differences in outcomes by VTE subtype were apparent with standard anticoagulation treatment. Conclusion XALIA-LEA reaffirms the safety and effectiveness of rivaroxaban for VTE treatment for countries not included in XALIA. Highlights • XALIA-LEA enrolled patients from global regions beyond those included in XALIA. • More patients with index PE received standard anticoagulation than rivaroxaban. • Outcome incidences were low with rivaroxaban therapy. • Outcome incidences with standard anticoagulation varied by index VTE type.
