ATLANTA, Georgia — New data from a pooled analysis of the EINSTEIN-DVT and EINSTEIN-PE in the treatment of deep venous thrombosis (DVT) or pulmonary embolism suggests that rivaroxaban (Xarelto, Bayer/ Janssen) is similarly effective in preventing recurrence of venous thromboembolism (VTE) as enoxaparin followed by a vitamin-K antagonist and may be associated with less bleeding. In addition, subgroup analysis showed reassuring results in specific high-risk populations such as elderly, fragile patients, those with cancer, and those with large clots. The data was presented at the American Society of Hematology (ASH) 2012 Annual Meeting by Dr Harry Buller (Academic Medical Center, Amsterdam, the Netherlands). He noted that the EINSTEIN-DVT and EINSTEIN-PE trials had identical noninferiority designs comparing oral rivaroxaban (15 mg twice daily for three weeks then 20 mg once daily thereafter for up to 12 months) with enoxaparin for five to 10 days followed by an oral v
