Background Patients with cancer‐associated thrombosis (CAT) have a high risk of recurrent venous thromboembolic events, which contribute to significant morbidity and mortality. Direct oral anticoagulants may provide a convenient treatment option for these patients. Objectives To assess clinical characteristics and outcomes of patients with active cancer changing to rivaroxaban after ≥4 weeks of standard therapy for the treatment of venous thromboembolism (VTE) in clinical practice. This analysis focused on secondary outcomes of Cancer‐associated thrOmboSIs – Patient‐reported outcoMes with rivarOxaban (COSIMO). Patients COSIMO was a multinational, prospective, noninterventional, single‐arm cohort study. Overall, 505 patients received at least one dose of rivaroxaban; 96.6% changing from low‐molecular‐weight heparin, 1.6% from a vitamin K antagonist, and 1.8% from fondaparinux. Results Most patients had solid tumors (n = 449; 88.9%) and approximately half of these patients had metastases. The qualifying venous thromboembolic event was deep vein thrombosis (DVT) in 45.3% of patients, pulmonary embolism (PE) in 37.2% of patients, DVT with PE in 9.7% of patients, and catheter‐associated DVT in 7.5% of patients. Approximately 75.1% of patients received rivaroxaban for at least 3 months; 150 (29.7%) patients received concomitant chemotherapy during the study. VTE recurrence, major bleeding, nonmajor bleeding, and major adverse cardiovascular events occurred in 18 (3.6%), 18 (3.6%), 81 (16.0%), and 12 (2.4%) patients, respectively. Conclusions In patients with CAT who changed to rivaroxaban treatment after ≥4 weeks of standard therapy, the observed incidence proportions of recurrent VTE and bleeding events were in keeping with the recognized effectiveness and safety profile of rivaroxaban for the treatment of CAT.
