MADRID—A pooled analysis of 2 studies suggests rivaroxaban prevents recurrent venous thromboembolism (VTE) in cancer patients as effectively as standard therapy, while conferring a lower risk of major bleeding.
The analysis included data from the EINSTEIN-DVT and EINSTEIN-PE trials, which were funded by the companies developing rivaroxaban (Xarelto), Bayer HealthCare Pharmaceuticals and Janssen Research & Development, LLC.
The results were published in Lancet Haematology and presented at the ESMO 2014 Congress (abstract LBA48).
The EINSTEIN-PE study included 3449 subjects with acute symptomatic pulmonary embolism (PE), with or without symptomatic deep vein thrombosis (DVT), who received anticoagulant therapy for 6 or 12 months.
The EINSTEIN-DVT study included 4833 patients who had acute symptomatic DVT, but no symptoms of PE, and received treatment for 3, 6, or 12 months.
In both studies, patients received either oral rivaroxaban (15 mg twice daily for 3 weeks, followed by 20 mg once daily) or standard therapy—enoxaparin (1.0 mg/kg twice daily) followed by a vitamin K antagonist (warfarin or acenocoumarol).
A total of 8281 patients were randomized in these studies—4150 to rivaroxaban and 4131 to standard therapy. Of the 655 patients (7.9%) with active cancer, 462 (5.6%) had cancer at baseline, and 193 (2.3%) were diagnosed during the study.
For this analysis, Martin H. Prins, MD, PhD, of Maastricht University Medical Center in The Netherlands, and his colleagues compared the 2 treatments in patients with active cancer.
VTE recurred in 4.5% (16/354) of the patients who were randomized to rivaroxaban and 6.6% (20/301) of patients randomized to standard therapy (hazard ratio [HR]=0.67).
The mortality rate was 16.4% (58/354) among patients randomized to rivaroxaban and 17.6% (53/301) among those randomized to standard therapy (HR=0.93).
Major bleeding occurred in 2.3% (8/353) of patients who received rivaroxaban and 5% (15/298) who received standard therapy (HR=0.42). And clinically relevant bleeding occurred in 13.6% (48/353) and 16.4% (49/298), respectively (HR=0.80).
Given these results, Dr Prins and his colleagues concluded that rivaroxaban can be considered an alternative to standard therapy in patients with cancer-associated VTE.
The team also said there is a need for a head-to-head comparison of rivaroxaban and long-term low-molecular-weight heparin in this patient population.
