Evaluation of Sirolimus-Eluting, Heparin-Coated CoCr Stent in the Treatment of de Novo Coronary Artery Lesions in Small Vessels(EVOLUTION)

June 26, 2007 updated by: Cordis Corporation

Sirolimus-Eluting, Heparin-Coated Cobalt Chromium Balloon-Expandable Stent in the Treatment of Patients With de Novo Coronary Artery Lesions in Small Vessels (EVOLUTION)

The objective of this study is to assess the performance and safety of a sirolimus-eluting, heparin-coated, cobalt chromium balloon-expandable stent (Small Vessel Stent) in patients with de novo native coronary artery lesions in small vessels as compared to historical data from small vessel patients in the RAVEL trial receiving the Sirolimus-eluting Bx VELOCITY™ stent.

Description

Inclusion Criteria:

  1. The patient must be minimum 18 years of age;
  2. Diagnosis of angina pectoris as defined by Canadian Cardiovascular Society Classification (CCS I, II, III, IV) OR unstable angina pectoris (Braunwald Classification B&C, I-II-III) OR patients with documented silent ischemia;

3 Treatment of one lesion in a native coronary artery. The treated lesion will be the one with the highest % diameter stenosis by visual estimate. Additional study stents may be used for procedural complications such as dissections. Multivessel treatment is permissible in non-target vessels; however, additional lesions may only be treated with commercial stents. If other non-target vessels are treated with commercial stents during the index procedure, they must be successfully treated prior to the study lesion;

4. The target lesion is >/=2.0 mm and </=2.5mm in diameter (visual estimate);

5. The target lesion can be covered with a single 18mm stent;

6. Target lesion stenosis is >50% and <100% (TIMI I) (visual estimate);

Exclusion Criteria:

  1. Patient has experienced a Q-wave or non-Q-wave myocardial infarction with documented total CK>2 times normal within the preceding 24 hours and the CK and CK-MB enzymes remain above normal at the time of treatment;
  2. Target lesion is due to in-stent restenosis;
  3. Ejection fraction 30%;
  4. Totally occluded vessel (TIMI 0 level);
  5. Impaired renal function (creatinine > 3.0 mg/dL);

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
The primary endpoint is in-stent late loss as measured by quantitative coronary angiography (QCA) at 6 months post-procedure.
Time Frame: 6 months post-procedure
6 months post-procedure

Secondary Outcome Measures

Outcome Measure
Time Frame
In-lesion late loss as measured by QCA at 6 months post-procedure.
Time Frame: 6 months post-procedure
6 months post-procedure
In-stent and in-lesion minimum lumen diameter (MLD) and percent diameter stenosis (%DS) by QCA post-procedure and at 6 months.
Time Frame: Post-procedure and at 6 months
Post-procedure and at 6 months
Device success defined as achievement of a final residual diameter stenosis of <50% (by QCA), using the assigned device only. If QCA is not available, the visual estimate of diameter stenosis is used.
Target Lesion Revascularization (TLR) at six and 12 months.
Time Frame: 6 and 12 months
6 and 12 months
Target Vessel Revascularization (TVR) at six and 12 months.
Time Frame: 6 and 12 months
6 and 12 months
Composite of Major Adverse Cardiac Events (MACE) defined as death, myocardial infarction (Q wave and non-Q wave), emergent bypass surgery, or repeat target lesion revascularization at 30 days, 6 months and 12 months post-procedure.
Time Frame: 30 days, 6 months and 12 months post-procedure
30 days, 6 months and 12 months post-procedure
Stent Lumen and Stent Obstruction Volume by Intravascular Ultrasound (IVUS) at post procedure and six months follow-up.
Time Frame: post procedure and six months
post procedure and six months
