Janssen Research & Development, LLC has introduced EXPLORER, a comprehensive, global research programme for XARELTO (rivaroxaban), an oral anticoagulant. The programme includes studies that will evaluate XARELTO for investigational use in patients with chronic heart failure and in those with coronary artery disease (CAD) or peripheral artery disease (PAD).

XARELTO does not require routine blood monitoring, and with approvals for six distinct uses, it has the broadest indication profile of any of the newer oral anticoagulants in the market today. XARELTO is approved in the US for reducing the risk of strokes in patients with non-valvular atrial fibrillation; as a treatment for deep vein thrombosis and pulmonary embolism and to prevent recurrence of these events; and for reducing the risk of blood clots in the legs and lungs of people who have had hip or knee replacement surgery.

The extensive programme of clinical trials evaluating XARELTO makes the compound the most studied oral, Factor Xa inhibitor in the world today. By the time of its completion, more than 100,000 patients will have participated in the XARELTO clinical development programme.

“Janssen is dedicated to improving patient outcomes in the cardiovascular space and the EXPLORER programme is one important way we are expressing our commitment to patients with unmet medical needs,” said Troy Sarich, vice president and compound development Team Leader at Janssen Research & Development. “The EXPLORER programme seeks to build upon the broad set of approved indications, and further assess potential benefits of XARELTO in additional patient populations who may benefit from oral anticoagulation treatment.

As part of the EXPLORER programme, Janssen and its development partner, Bayer HealthCare, will enroll patients into five global clinical trials:

Firstly, COMMANDER-HF will evaluate XARELTO in patients with chronic heart failure and significant coronary artery disease who are receiving standard care. The study will include 5,000 patients in 12 countries.

Secondly, COMPASS will evaluate XARELTO in patients with coronary artery disease or peripheral artery disease. This study includes 20,000 patients across 25 countries and will be conducted in collaboration with the Population Health Research Institute (PHRI) at McMaster University in Hamilton, Canada.

Thirdly, PIONEER AF-PCI will evaluate XARELTO in 2,100 patients who have non-valvular atrial fibrillation and are undergoing percutaneous coronary intervention (PCI) with stent placement. The trial will assess XARELTO in combination with dual antiplatelet therapy and when aspirin is not used.

X-VeRT will evaluate patients with atrial fibrillation scheduled for cardioversion – a medical procedure to convert abnormally fast heart rate to a normal rhythm, using electricity or antiarrhythmic medications. The study includes 1,500 patients across 17 countries and will compare XARELTO to dose-adjusted vitamin K antagonist.

VENTURE-AF will evaluate the use of XARELTO in patients with non-valvular atrial fibrillation undergoing catheter ablation, a procedure that uses energy delivered through catheters to eliminate the abnormal tissue that is causing the arrhythmia. The study will include up to 250 patients in four countries.

In addition, as part of our ongoing commitment to expanding therapeutic choices for health care professionals, Janssen recently announced a clinical collaboration agreement with Portola Pharmaceuticals, Inc. and Bayer HealthCare to evaluate an investigationalstage antidote for Factor Xa inhibitors. This proof-of-concept study is scheduled to complete in the second half of 2013.

On March 4, 2012, Janssen announced the US Food and Drug Administration (FDA) issued a second complete response letter regarding a supplemental New Drug Application for XARELTO for the reduction of the risk of cardiovascular events in patients with acute coronary syndrome. Janssen is evaluating the letter and will respond to the agency’s questions.

XARELTO works by blocking the blood clotting Factor Xa. It is approved for six distinct uses: to reduce the risk of blood clots in the legs and lungs of people who have just had knee replacement surgery; to reduce the risk of blood clots in the legs and lungs of people who have just had hip replacement surgery; to reduce the risk of both hemorrhagic and thrombotic strokes as well as other blood clots in people with atrial fibrillation not caused by a heart valve problem. There is limited information on how XARELTO compares to a medicine called warfarin in reducing the risk of stroke when the effects of warfarin are well controlled; to treat people with pulmonary embolism (PE); to treat people with deep vein thrombosis (DVT); to reduce the risk of recurrence of DVT or PE following an initial six months of treatment for acute venous thromboembolism.

Janssen Research & Development, LLC, and Bayer HealthCare together are developing rivaroxaban. Janssen Pharmaceuticals, Inc. holds U.S. marketing rights for XARELTO and is supported by the Bayer HealthCare U.S. sales force.

Janssen is dedicated to addressing and solving some of the most important unmet medical needs of our time in oncology, immunology, neuroscience, infectious diseases and vaccines, and cardiovascular and metabolic diseases.
