Abstract
The effectiveness and safety of acute venous thromboembolism (VTE) treatment with rivaroxaban, demonstrated in phase-III trials, needs to be confirmed in daily care. To confirm the positive results of phase-III VTE treatment trials with rivaroxaban in daily care, we used data from the ongoing, prospective, non-interventional Dresden NOAC Registry. For this analysis, only patients with acute VTE who started rivaroxaban within 14days after diagnosis of VTE and who were enrolled within these 14days were evaluated with regard to patient characteristics, treatment persistence and clinical outcomes. Between December 1st 2011 and 30th September 2016, 418 patients with acute VTE and rivaroxaban treatment were enrolled. During rivaroxaban treatment (median rivaroxaban exposure 206d; median follow-up 862d) rates of recurrent VTE and ISTH major bleeding were 1.9% and 3.8%, respectively. At 6months. 58.3% of patients were still taking rivaroxaban, 28.2% had a scheduled end of treatment, 7.2% were switched to other anticoagulants, 1.7% had withdrawn their consent and the remaining 3.6% of patients had unplanned complete discontinuation of anticoagulation. After permanent discontinuation of rivaroxaban, 20 patients experienced a recurrent VTE (7 pulmonary embolism±deep vein thrombosis, 13 deep vein thrombosis) with a mean time between last intake of rivaroxaban and VTE recurrence of 374.3±247.6days (range 28-927d). In daily care patients with acute VTE, rivaroxaban demonstrated high effectiveness with acceptable major bleeding rates. Initial dosing was according to label in over 90% of patients and persistence to rivaroxaban therapy was adequate with low rates of unplanned complete discontinuation.
