The Alirocumab for Stopping Atherosclerosis Progression in Saphenous Vein Grafts (ASAP-SVG) Pilot Trial

Summary

This is a phase IV, multi-center, double-blind, randomized, placebo- controlled study evaluating the effect of alirocumab on SVG atherosclerotic disease burden, as assessed by IVUS at baseline and following 78 weeks of treatment in subjects with at least one intermediate SVG lesion receiving optimal statin therapy. Subjects will be randomized 1:1 into 2 treatment groups: alirocumab 150 mg subcutaneously every 2 weeks or placebo subcutaneously every 2 weeks.
