Peripheral Arterial Disease

The purpose of study is to test whether rivaroxaban added to standard of care treatment, when compared to placebo, has the potential to reduce the incidence of the clinical events related to the clots and complications of the heart and brain (CV death, MI, or stroke) or the legs (acute limb ischemia or major amputation) in patients who had undergone recent procedure(s) to improve the blood flow of their legs. 

A randomized, double-blind placebo controlled study to determine the safety and efficacy of Angiogenic Cell Precursors (ACPs) in relieving symptoms of Critical Limb Ischemia in patients treated with standard of care and with no surgical revascularization option. It is assumed that the ACP-treated group will have a lower amputation and death rate as compared to the placebo group. Other hemodynamic, imaging and clinical parameters will also be compared between the two groups. Quality of life assessments will also be performed.
