FDA Approves XARELTO® (rivaroxaban tablets) to Help Prevent Deep Vein Thrombosis in Patients Undergoing Knee or Hip Replacement Surgery
XARELTO® is the only new oral anticoagulant with FDA approval in this indication
Raritan, NJ (July 1, 2011) /PRNewswire/ - Janssen Pharmaceuticals, Inc. announced today that the U.S. Food and Drug Administration (FDA) has approved XARELTO® (rivaroxaban tablets), a novel, once-daily, oral anticoagulant for the prevention (prophylaxis) of deep vein thrombosis (DVT) which may lead to a pulmonary embolism (PE) in people undergoing knee or hip replacement surgery.

"The approval of once-daily XARELTO® tablets will provide a new option to help protect patients from developing venous blood clots following knee or hip replacement surgery," said Louis M. Kwong, M.D., Professor of Orthopedic Surgery at Harbor-UCLA Medical Center, who was involved with the rivaroxaban clinical trials program in this indication. "XARELTO® has a proven clinical benefit over one of today's most widely used options in preventing these potentially life-threatening blood clots, and the use of a once-daily pill may play an essential role in helping to simplify clinical practice."

According to the American Academy of Orthopedic Surgeons, more than 800,000 Americans undergo knee or hip replacement surgery each year. These procedures are associated with an increased risk for DVT, a blood clot that forms in a deep vein, usually in the leg. If all or part of a DVT breaks off, it can travel to the lungs and become a PE, where it may impact the flow of oxygenated blood and lead to potentially life-threatening consequences.

The American College of Chest Physicians recommends the use of blood thinners (anticoagulants) immediately following major orthopedic replacement surgery and extended use post-discharge (at least 10 days for knee replacement, and up to 35 days for hip replacement) to help reduce such risks; however, full compliance with these guidelines using previously available options has not been widely observed. DVT and PE are the leading causes of re-hospitalization following joint replacement surgery.

"The use of blood thinners has been shown to safely and effectively help keep people from developing preventable blood clots," said Alan Brownstein, Chief Executive Officer of the National Blood Clot Alliance. "The FDA approval of a new blood thinner, XARELTO®, offers a new option for patients seeking knee or hip replacement surgery, and we encourage people to discuss with their physicians the risk of blood clots and which blood thinner offers optimal protection as part of their pre-surgical consultation."

Pivotal data from the XARELTO® Phase 3 clinical development program reflected in the approved label showed significantly greater efficacy of rivaroxaban, both in head-to-head comparison with enoxaparin and when comparing extended-duration (5 weeks) rivaroxaban with short-duration (2 weeks) enoxaparin, followed by placebo. In these trials, rivaroxaban and enoxaparin demonstrated similar safety profiles including low rates of major bleeding.

XARELTO® is approved for use at a 10 mg dose, once-daily for 35 days following hip replacement and for 12 days following knee replacement surgery. To date, XARELTO® is approved in more than 110 countries worldwide and has been successfully launched in more than 80 countries by Bayer HealthCare. Janssen Pharmaceuticals, Inc. holds marketing rights for XARELTO® in the U.S. The U.S. Bayer HealthCare sales force will support the Janssen Pharmaceuticals, Inc. sales force by detailing XARELTO® in designated hospital accounts.

"Shorter hospital stays following hip and knee replacement surgeries have made the prevention of venous blood clots an outpatient issue, and XARELTO® provides a safe and effective oral treatment option that can be easily transitioned from use in hospital to home," said Paul Chang, M.D., Vice President, Medical Affairs, Internal Medicine, Janssen Pharmaceuticals, Inc. "We're pleased to make XARELTO® tablets available to physicians to help them better protect their patients from these highly preventable surgical complications."

About XARELTO® (rivaroxaban tablets)

XARELTO® is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in people undergoing knee or hip replacement surgery. XARELTO® belongs to a group of medicines called anticoagulants. It works by blocking the blood clotting Factor Xa and thereby reduces the tendency of the blood to form clots.

XARELTO® is the third New Drug Application the U.S. FDA has approved from the Janssen Pharmaceutical Companies this year.

Additionally, XARELTO® is being evaluated for the prevention and treatment of a broad range of disorders in which blood clotting plays a major role. The extensive program of clinical trials evaluating rivaroxaban makes the compound the most studied oral, Factor Xa inhibitor in the world today. By the time of its completion, more than 65,000 patients will have participated in the rivaroxaban clinical development program. Rivaroxaban is being developed jointly by Johnson & Johnson Pharmaceutical Research & Development, L.L.C. and Bayer HealthCare.
