SAFE (Sarpogrelate Anplone in Femoro-popliteal Artery Intervention Efficacy) Study


After endovascular treatment (EVT) for peripheral artery disease (PAD), dual antiplatelet therapy (DAAT) of aspirin (ASA) and clopidogrel are currently drug of choice to prevent occlusion. Anplone SR®, controlled-released Sarpogrelate hydrochloride, has been introduced as an anti-platelet agent for the drug of PAD. The aim of this study was to compare the efficacy and safety of Anplone + aspirin and clopidogrel + aspirin in patients who underwent EVT for femoro-popliteal occlusive disease.
