Comparative Phase IV Study: Efficacy And Safety of TiTAN2 Versus COBALT-CHROME Stents- EVIDENCEII
- Conditions
- Silent Myocardial InfarctionStable AnginaAcute Coronary Syndrome
- Registration Number
- NCT01918150
- Lead Sponsor
- Hexacath, France
- Brief Summary
The purpose of this study is to compare the effectiveness and safety, at 24 months, of the TITAN2 stent to any bare-metal stent (BMS) in Cobalt-Chromium in a population presenting an indication for these stents among 40% of which present an acute coronary syndrome (ACS).
- Detailed Description
The EVIDENCE II trial is a post-registration study for TITAN2 stent initiated on the request of the French Health Authorities' (HAS) in June 2009 for the next renewal of registration on the list of reimbursable products and services in France.
The study is so designed to compare the effectiveness and safety at 24 months of the TiTAN2 versus Cobalt-Chromium BMS randomly assigned. As a part of the secondary objectives, a cost-effectiveness study is also planned.
The comparators are cobalt chromium stents CE marketed and free of any coating (nude BMS).
All will be used in their authorized indications.
A total of 1350 patients will be included over a period of a year or more and followed for 24 months for the primary endpoint (MACE rate at 24 months in the overall population : cumulative incidence of cardiac deaths, MI and target lesion revascularization (TLR)).
Patients will also be clinically followed at 6 and 12 months . Medico economic datas are to collect at a similar time point.
An independent Clinical Event Committee, unaware of the treatment allocation, will be in charge of the adjudication of all the cardiac events including MACE (main objective)collected.
The calculation of the number of subjects specifies that 1350 patients are needed to meet the primary endpoint of the study.
Enrolled patient will be randomly assigned in a 2:1 fashion as follows :
* 900 patients in TITAN2 arm including 360 with ACS (Arm A)
* 450 patients in Cobalt-chromium arm including 180 with ACS (Arm B) In case of more than one stent needed, the protocol mandated using the same stent than the one assigned in all the lesions treated.

Study & Design

- PARALLEL
- Primary Outcome Measures
Name Time Method MACE 24 months The primary endpoint (MACE) is the composite of cardiac death, (Myocardial Infarction) MI and target lesion revascularization (TLR).
These events will be collected post-procedure during the patient's hospitalization and at 6 , 12 and 24 month follow-up.
- Secondary Outcome Measures
Name Time Method Medico economic evaluation 24 months Data collection of acts and diagnosis specific codes related to any adverse event with hospitalization in relation with the endoprothesis allocated.
It will be then analyzed by an dedicated expert who will be able to appreciate a cost/efficiency rate for each treatment arm.Target Lesion Revascularization (TLR ) rate 24 months Any study stent restenosis leading to a procedure or a surgery to treat it.
Stent thrombosis rate 24 months Stent thrombosis will be evaluated as per the ARC classification (ie degree of evidence and time to event)
Success of the procedure 24 months Defined as an efficient reintroduction of the blood flow in the target vessel post angioplasty.
It's a "YES/NO" question.
