Brief summary (from the registry)

This study will evaluate UT-15C sustained release tablets in subjects experiencing ischemic lower limb rest pain related to advanced peripheral arterial disease. Rest pain is one of the primary management issues of severe arterial occlusive disease and may lead to amputation when the pain becomes intolerable and unresponsive to narcotic analgesia. Rest pain also impacts the quality of sleep and mobility with frequent interruptions in sleep and decreased mobility. Treprostinil sodium (Remodulin®) has been studies in several small open-label studies and has been shown to be safe as well as an effective agent for ischemic rest pain when given by subcutaneous or intravenous delivery. However, these forms of administration have patient convenience limitations, including the need for an infusion device and associated pain at the site of infusion with subcutaneous delivery. UT-15C may allow patients suffering from CLI to benefit from the simplicity of an oral dosage form
