About this study

The CVT-ISR Trial is a prospective, multi-center, open, single arm study enrolling subjects with visually estimated nominal vessel diameter ≥2.0 mm and ≤3.5mm and lesion length ≤24 mm receiving up to two (2) CVT Everolimus CVT EVE-PTCA Catheters.

An angiographic follow up, in combination with either Intravascular Ultrasound (IVUS) or Optical Coherence Tomography (OCT), follow-up, will be carried out in a subset of 25 patients at 180 days following the index procedure.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subject must be at least 18 years of age.
  • Subject or his/her legally authorized representative provides written informed consent prior to any clinical investigation related procedure, as approved by the appropriate Ethics Committee of the respective clinical site.
  • Subject must agree to undergo all clinical investigation plan-required follow-up visits, angiograms, IVUS/OCT and examinations.

Angiographic Inclusion Criteria

  • Target lesion must be located within a stent (bare metal or drug eluting) placed in a native epicardial coronary vessel with visually estimated nominal vessel diameter of ≥2.0mm and ≤3.5mm.
  • Target lesion must measure ≤24 mm in length by visual estimation.
  • The target lesion must be with a visually estimated stenosis of ≥50% and < 100% with a TIMI flow of ≥1.
  • Non-clinical investigation, percutaneous intervention for lesions in a non-target vessel is allowed if done ≥90 days prior to or planned to be done 6 months after the index procedure.
  • Non-clinical investigation, percutaneous intervention for lesions in the target vessel is allowed if planned to be done 6 months after the index procedure.

Exclusion criteria

  • Subject with known diagnosis of acute myocardial infarction (AMI) within 30 days preceding the index procedure and CK-MB or troponin have not returned within normal limits at the time of procedure.
  • The subject is currently experiencing clinical symptoms consistent with AMI.
  • Subject has current unstable arrhythmia.
  • Subject has a known left ventricular ejection fraction (LVEF) <25%.
  • Subject has a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, both clopidogrel and ticlopidine and structurally related compounds, everolimus, or contrast sensitivity that cannot be adequately pre-medicated.
  • Subject has known renal insufficiency (e.g., serum creatinine > 2.5 mg/dL, (i.e. 221 µmol/L) within 7 days prior to index procedure or creatinine clearance <30mL/min or subject is on dialysis.
  • Subject has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions.
  • Subject has had a cerebrovascular accident (CVA) or transient ischemic neurological attack (TIA) within the past six months.
  • Subject has other medical illness (e.g., cancer or congestive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the clinical investigation plan, confound the data interpretation or is associated with a limited life expectancy (i.e., less than one year).
  • Subject is already participating in another clinical investigation that has not yet reached its primary endpoint.
  • Subject is not, in the opinion of the investigator, an acceptable candidate to participate in the study.
  • In-stent lesions for stent are located within an arterial or saphenous vein graft or stent used to treat a previous ISR.
  • The target vessel contains visible thrombus.
  • Pregnant or lactating females.

Primary outcomes

  1. The Primary Safety Endpoint for the CVT-ISR Study: Freedom From Target Lesion Failure (TLF) Rate

    Time frame: 6 months post-index procedure

    Composite rate of cardiovascular death, target vessel myocardial infarction and clinically-driven target lesion revascularization (TLR).

  2. The Primary Effectiveness Endpoint for the CVT-ISR Study: In-stent Late Lumen Loss (LLL)

    Time frame: 180 days post-procedure

    In-Stent Late Lumen Loss (LLL) measures the reduction in the luminal diameter of a stented artery over a specified period after stent implantation, typically assessed using angiographic imaging. The unit of measurement for this outcome is expressed in millimeters (mm) or percentage (%), depending on the reporting method. The LLL is calculated by comparing the luminal diameter at a follow-up time point to the post-procedure luminal diameter.

Secondary outcomes

  1. Composite Rate of Target Lesion Failure (TLF)

    Time frame: 30 days post-procedure, 12 months, 24 months and 36 months

    TLF is defined as composite rate of cardiovascular death, target vessel myocardial infarction and clinically-driven target lesion revascularization (TLR).

  2. Composite Rate of Target Vessel Failure (TVF)

    Time frame: 30 days post-procedure, 180 days, 12 months, 24 months and 36 months

    Target vessel failure (TVF) is defined as composite rate of cardiovascular death, target vessel myocardial infarction, and target vessel revascularization (TVR).

  3. Clinically Driven Target Lesion Revascularization (TLR)

    Time frame: 12 months, 24 months and 36 months

    TLR is defined as any repeat PCI of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion.

  4. Clinically-driven Target Vessel Revascularization (TVR)

    Time frame: 180 days, 12 months, 24 months and 36 months

    TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel including the target lesion.

  5. Rate of Vascular Access Site Complications

    Time frame: 12 months

    The rate of vascular access site complications is defined as the combined rate of hematoma, AV fistula or a pseudoaneurysm that required intervention, such as surgical repair, transfusion or a prolonged hospital stay or requiring a new hospital admittance.

  6. Lesion Success:

    Time frame: 12 months

    Lesion success, defined as achievement of a final in-lesion residual diameter stenosis of <30% (by QCA), using any device after wire passage through the lesion.

  7. Technical Success

    Time frame: 12 months

    Technical success, defined as achievement of a final in-lesion residual diameter stenosis of <30% (by QCA), using the CVT Everolimus coated PTCA Catheter without a device malfunction after wire passage through the lesion.

  8. Clinical Success (Per Subject)

    Time frame: 12 months

    Clinical success (per subject) defined as technical success without the occurrence of major adverse cardiac events during the procedure.

  9. Procedural Success

    Time frame: 12 months

    Procedural success (per subject) defined as lesion success without the occurrence of major adverse cardiac events during the procedure.
