Optical Coherence Tomography to Evaluate Ticagrelor and Clopidogrel

Thrombosis Clinical Trial

Official title:
A Randomised, Open-label, Parallel Group, Multi-center Study Using OCT to Comparing the Efficacy and Safety of Ticagrelor With Clopidogrel in the Prevention of Subclinical Thrombus in Patients After Drug-eluting Stent Implantation

Clinical Trial Summary

A number of 352 patients scheduled for elective percutaneous coronary intervention (PCI) with a native coronary stenosis suitable for DES implantation and OCT imaging are openly randomized 1:1 to either BRILINTA™ (ticagrelor) or Plavix® (clopidogrel bisulfate).

Clinical Trial Description

The study is prospectively conducted at 4 high-volume PCI center in China with OCT expertise. Angiographic follow-up and OCT imaging with motorized pull-back at 20-36 mm/s are planned in all patients 12 months after implantation of the study stents. OCT endpoints are: (1) Subclinical intra-stent thrombus, defined as a mass protruding to the lumen with significant attenuation, and respectively (2) endothelial coverage, expressed as % of struts without coverage and % of stent length containing non-covered struts. The study is powered for OCT endpoints, which are likely to reach significance at the level P < 0.05 even at a follow-up drop-out rate up to 10%. ;
