Comparison of Strut Coverage With OPTIMAX Versus SYNERGY Stents — OPTIMAX-OCT  

Acute Coronary Syndrome Clinical Trial

Official title: A Randomized Prospective Multicenter Trial to Examine Vascular Healing at 1 and 6 Month(s) After Deployment of TItanium-nitride-oxide-coated OPTIMAX™ Bio-active-stent (BAS) Stent and SYNERGY™ Everolimus-Eluting Stent (EES) in Patients With Acute Coronary Syndromes by Means of Optical Coherence Tomography

Clinical Trial Summary

The purpose of this study is to compare vascular healing of the stented segment after deployment of titanium-nitride-oxide coated cobalt-chromium OPTIMAX™ bio-active stent (BAS) and SYNERGY™ everolimus-eluting stent (EES) in patients with acute coronary syndromes requiring percutaneous coronary intervention.

Patients treated with BAS will be treated with DAPT for at least 4 weeks after the procedure followed by aspirin alone, while patients in the EES group will be treated with DAPT, at least for 6 months post procedure. In addition, this study will collect initial information about the safety and effectiveness of the BAS in comparison with EES group at 30 days, 6 months, and 12 months.

Clinical Trial Description

OPTIMAX-OCT is a prospective, randomized (1:1), study that will be conducted at 2-3 sites (Finland, Belgium) to evaluate OPTIMAX-BAS vascular healing patterns and thrombus formation with OCT at one (Study A) and six (Study B) month after stent implantation in comparison with SYNERGY-EES. Patients receiving BAS will receive dual antiplatelet treatment (DAPT) for at least four weeks followed by aspirin, while patients implanted with EES, will receive DAPT for at least 6 months followed by aspirin.

Patients will be randomized to study A and B as follow:

Study A: OPTIMAX-BAS (n=25) versus SYNERGY-EES (n=25). First 50 patients will be randomized to study A. OCT at 1 month follow up.

Study B: OPTIMAX-BAS (n=30) versus SYNERGY-EES (n=30) Following 60 patients will be randomized to study B. OCT at 6 months follow up.

Randomization is used at the time of recruitment with sealed envelopes. Patients will be randomized in 1:1 fashion. First 50 patients are randomized in study A and following 60 patients in study B. Patients in study A will have OCT follow up at 1 month after index procedure and patients in study B will have OCT at 6 months.

OCT analyses will be performed blinded to patient's characteristics as well as the type of the stent used.
