Clinical Trial Summary

Ticagrelor-based De-escalation of Dual Antiplatelet Therapy After Coronary Artery Bypass Grafting trial (TOP-CABG trial) is a multicenter, randomized, double-blind, non-inferiority, parallel controlled trial. The aim of TOP-CABG is to investigate whether de-escalated dual antiplatelet therapy (De-DAPT) is non-inferior to dual antiplatelet therapy (DAPT) in efficacy on inhibiting great saphenous vein (SVG) graft occlusion and is superior in reducing bleeding events in patients accepting coronary artery bypassing grafting.


Clinical Trial Description

After informed consent, at least 10 centers and 2,300 eligible admissions will be recruited. Eligible patients would be randomized (1:1) in double-blind manner (patients and treating physicians) to dual antiplatelet therapy (DAPT) group (ticagrelor 90mg bid and aspirin 100 mg qd for 12 month) and de-escalated DAPT (De-DAPT) group (90mg bid and aspirin 100 mg qd for first 3 months, and then aspirin 100 mg qd and placebo for 9 months). ;
