Clinical Trial Summary

Assessing the outcomes of using Rivaroxaban plus Aspirin in patients with Lower Extremity Peripheral Arterial Disease after Endovascular Revascularization

Clinical Trial Description

Globally more than 200 million people suffer from peripheral artery disease (PAD), and the incidence is rising due to advancing age, high rates of smoking in certain regions of the world, and the rising incidence of type 2 diabetes. PAD patients have wide-spread atherosclerosis and suffer a high risk of major cardiovascular (CV) events, with atherothrombosis as the underlying pathophysiologicmechanism. Symptomatic peripheral artery disease (PAD) is associated with a reduction in exercise capacity and quality of life and risk for tissue loss that is often treated with lower extremity revascularization (LER) to relieve symptoms and to prevent limb loss in a large portion of the population. PAD is also associated with a heightened risk for major adverse cardiovascular and limb events. LER is associated with a substantial increased risk of ischemic cardiovascular and limb events, including a 4-fold increased risk for acute limb ischemia (ALI), an ≈30% increased risk of myocardial infarction (MI), and an increased risk of rehospitalization after LER. Observations from a large administrative database showed that patients with PAD after LER had an early heightened risk for ischemic limb events and a later increased risk for cardiovascular events. Despite the common use of dual antiplatelet therapy after endovascular LER, this strategy is not supported by any Class 1A PAD guideline recommendations. Guidelines do give Class IIB recommendation for dual antiplatelet therapy for endovascular and surgical procedures (American and European) and Class IIA recommendation with Level of Evidence C for endovascular procedures (European),whereas use of dual antiplatelet therapy is discouraged by the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. Recently Antiplatelet therapy with low-dose factor Xa inhibition with rivaroxaban 2.5 mg twice daily used in combination with aspirin have been shown to reduce ischemic cardiovascular and limb events in patients with stable PAD. In patients with PAD undergoing LER, the VOYAGER PAD trial (Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease) demonstrated superiority of the combination of rivaroxaban 2.5 mg twice daily plus aspirin 100 mg daily versus placebo plus aspirin on the composite outcome of ALI, major amputation of a vascular pathogenesis, cardiovascular death, ischemic stroke, or MI, but with a numeric increase in major TIMI (Thrombolysis in Myocardial Infarction) bleeding. So, Investigators decided to assess the outcomes of using Rivaroxaban 2.5 mg twice daily plus Aspirin 100 mg in patients with lower extremity PAD after endovascular revascularization ;
