Descriptive Information
Brief Title  ICMJE Disrupt CAD III With the Shockwave Coronary IVL System
Official Title  ICMJE Prospective, Multicenter, Single-Arm, Global IDE Study of the Shockwave Coronary Intravascular Lithotripsy (IVL) System With the Shockwave C2 Coronary IVL Catheter in Calcified Coronary Arteries
Brief Summary The study design is a prospective, multicenter, single-arm, global IDE study to evaluate the safety and effectiveness of the Shockwave Medical Coronary Intravascular Lithotripsy (IVL) System in de novo, calcified, stenotic coronary arteries prior to stenting. Disrupt CAD III is being conducted as a staged pivotal study.
Detailed Description Subject Population: Subjects ≥ 18 years of age with de novo, calcified coronary artery lesions presenting with stable, unstable or silent ischemia that are suitable for percutaneous coronary intervention (PCI). Approximately 392 subjects at 50 sites will be enrolled. A minimum of 50% of the total enrollment will come from the United States.Subjects will be followed through discharge, 30 days, 6, 12 and 24 months.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Intervention Model: Single Group Assignment
Intervention Model Description:
The Coronary IVL System is a proprietary balloon catheter system designed to enhance stent outcomes by enabling delivery of the calcium disrupting capability of lithotripsy prior to balloon dilatation at low pressures. The Coronary IVL System consists of an IVL Balloon Catheter with two integrated pairs of lithotripsy emitters, a Lithotripsy Generator, and Connector Cable.
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Coronary Artery Disease
  • Myocardial Infarction
Intervention  ICMJE Device: Lithotripsy
Deliver Lithotripsy to the target vessel prior to placing a coronary stent.
Study Arms  ICMJE Experimental: Coronary Lithotripsy System
All subjects will receive lithotripsy treatment from the Shockwave Medical Coronary IVL System
Intervention: Device: Lithotripsy

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Subject is ≥18 years of age
  2. Subjects with native coronary artery disease (including stable or unstable angina and silent ischemia) suitable for PCI
  3. For patients with unstable ischemic heart disease, biomarkers (troponin or CK-MB) must be less than or equal to the upper limit of lab normal within 12 hours prior to the procedure (note: if both labs are drawn, both must be normal).
  4. For patients with stable ischemic heart disease, biomarkers may be drawn prior to the procedure or at the time of the procedure from the side port of the sheath.

    1. If drawn prior to the procedure, biomarkers (troponin or CK-MB) must be less than or equal to the upper limit of lab normal within 12 hours of the procedure (note: if both labs are drawn, both must be normal).
    2. If biomarkers are drawn at the time of the procedure from the side port of the sheath prior to any intervention, biomarker results do not need to be analyzed prior to enrollment (note: CK-MB is required if drawn from the sheath).
  5. Left ventricular ejection fraction >25% within 6 months (note: in the case of multiple assessments of LVEF, the measurement closest to enrollment will be used for this criteria; may be assessed at time of index procedure)
  6. Subject or legally authorized representative, signs a written Informed Consent form to participate in the study, prior to any study-mandated procedures
  7. Lesions in non-target vessels requiring PCI may be treated either:

    1. >30 days prior to the study procedure if the procedure was unsuccessful or complicated; or
    2. >24 hours prior to the study procedure if the procedure was successful and uncomplicated (defined as a final lesion angiographic diameter stenosis <30% and TIMI 3 flow (visually assessed) for all non-target lesions and vessels without perforation, cardiac arrest or need for defibrillation or cardioversion or hypotension/heart failure requiring mechanical or intravenous hemodynamic support or intubation, and with no post-procedure biomarker elevation >normal; or
    3. >30 days after the study procedure

    Angiographic Inclusion Criteria

  8. The target lesion must be a de novo coronary lesion that has not been previously treated with any interventional procedure
  9. Single de novo target lesion stenosis of protected LMCA, or LAD, RCA or LCX (or of their branches) with:

  10. The target vessel reference diameter must be ≥2.5 mm and ≤4.0 mm
  11. The lesion length must not exceed 40 mm
  12. The target vessel must have TIMI flow 3 at baseline (visually assessed; may be assessed after pre- dilatation)
