Phase II clinical trial results published today in Circulation (2006;114:2374-2381) highlight the potential of a simple, once-daily dosing regimen of the novel, oral anticoagulant rivaroxaban (BAY 59-7939), a direct Factor Xa inhibitor. In this trial, rivaroxaban demonstrated that it may have similar safety and efficacy to subcutaneous enoxaparin (the current standard), for the prevention of venous thromboembolism (VTE) in patients undergoing elective total hip replacement surgery.
