The submission to the MHLW is based on the results of the global ROCKET AF study and the Phase III J-ROCKET AF study, which was run entirely in Japan. Both studies investigated rivaroxaban versus dose-adjusted warfarin in patients with non-valvular atrial fibrillation at risk of stroke. The J-ROCKET AF trial was conducted with a 15 mg dose of rivaroxaban once daily, in recognition of the Japanese guideline environment. Results of the J-ROCKET AF study are planned to be presented at an upcoming major scientific meeting.
As communicated in January 2011, rivaroxaban 20 mg once daily has previously been submitted for marketing authorization in stroke prevention in patients with atrial fibrillation in the EU and the US. These submissions were supported by data from the pivotal, global Phase III ROCKET AF trial that was presented at the American Heart Association (AHA) Congress in November 2010. About Rivaroxaban
Rivaroxaban is an oral anticoagulant that was invented in Bayer HealthCare's Wuppertal laboratories in Germany, and is being jointly developed by Bayer HealthCare and Johnson & Johnson Pharmaceutical Research & Development, L.L.C. It has a rapid onset of action with a predictable dose response and high bioavailability, no requirement for coagulation monitoring, as well as a limited potential for food and drug interactions.
Rivaroxaban is marketed under the brand name Xarelto® for the prevention of venous thromboembolism (VTE) in adult patients following elective hip or knee replacement surgery. Xarelto® is approved in more than 100 countries worldwide and has been successfully launched in more than 80 countries by Bayer HealthCare.
The extensive clinical trial program supporting rivaroxaban makes it the most studied oral, direct Factor Xa inhibitor in the world today. In total, more than 65,000 patients are expected to participate in the rivaroxaban clinical development program evaluating the product in the prevention and treatment of a broad range of venous and arterial thromboembolic diseases, including VTE treatment and secondary prevention of acute coronary syndrome (ACS).
