Brief Summary

Evaluation of Endothelial ProGenitor Cell Capture Sirolimus-Eluting Stent by Optical Coherence Tomography: the COMBO Stent angiographic extension Study (EGO-COMBO angiographic extension Study)

Conditions

Coronary Disease

Keywords

Optical Coherence Tomography; Geneous Stent; Combo Stent

Outcome Measures

Primary Outcomes (1)

• Co-primary end-points of OCT findings on coverage (degree of endothelialization) and OCT findings on late loss (late tissue growth, plaque volume, lumen cross sectional area), binary restenosis and late angiographic late loss by QCA at two years restudy.

  At the two year restudy date

Secondary Outcomes (1)

• Any major adverse cardiac events at two years restudy.

Study Arms (1)

The Combo Stent

EXPERIMENTAL

The COMBO Stent is developed basing on the GENOUS stent platform, and in addition, it also delivers a drug called sirolimus to the treated coronary blood vessel. The stent's original CD34 antibody coating is designed to promote healing of the coronary artery by catching circulating endothelial progenitor cells as they pass through the stent. These cells are naturally flowing in the circulation and are responsible for endothelial healing. This is intended to help the blood vessel wall heal over the stent more quickly and restore normal tissue function in the stented area. The combination of these two technologies in this new COMBO stent is expected to produce even better clinical results, which have been investigated in the previous REMEDEE Study.
