ATLANTA--(BUSINESS WIRE)--Phase III clinical trial results released today underscore that rivaroxaban, the oral, once-daily, investigational anticoagulant, was significantly more effective than enoxaparin, the standard of care, in preventing venous thromboembolism (VTE) in patients undergoing total hip or knee replacement surgery. Rivaroxaban-treated patients consistently experienced lower rates of VTE events compared to enoxaparin-treated patients across three large studies as well as demonstrating a similar rate of major bleeding events. Rivaroxaban is being jointly developed by Johnson & Johnson Pharmaceutical Research & Development, L.L.C. and Bayer HealthCare AG.
