Thromboprophylaxis with rivaroxaban in patients with malignancy and central venous lines (TRIM-Line): A two-center open-label pilot randomized controlled trial.
Summary
Purpose of the Pilot Trial:
To determine the feasibility of conducting a multicentre randomized open label controlled trial evaluating the use of prophylactic dose rivaroxaban to prevent central venous catheter (CVC) associated venous thromboembolism (VTE) among cancer patients.
Hypothesis: treatment with low dose rivaroxaban (10mg) will reduce the incidence of upper extremity venous thrombosis in a high risk population with cancer and CVC.
