Peripheral Artery Disease (PAD) is a manifestation of systemic atherosclerosis, and patients with PAD commonly manifest symptoms of intermittent claudication (IC) such as cramping, aching, or fatigue in the calf muscles provoked by activity. In PAD, arterial occlusions lead to decreased leg blood flow during exercise or walking and the pain associated with this ischemia is IC. The diffusion of oxygen from blood to muscle could be a component of the overall decreased delivery or deficit of oxygen (hypoxia) to skeletal muscle resulting in symptoms in PAD patients. The overall goal of the development of TSC as a treatment for PAD is to allow for enhanced diffusion of oxygen through the plasma to alleviate the symptoms caused by the hypoxia in the tissues.
