Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study design is a prospective, multicenter, single-arm 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.
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. Approximately 72 subjects at 8 sites in Japan will be enrolled. Subjects will be followed through discharge, 30 days, 6, 12 and 24 months.

- Model description
- The Coronary IVL System is a proprietary balloon catheter system designed to enhance stent outcomes by enabling delivering 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 2 integrated emitters, a Lithotripsy Generator, and a Connector Cable.

Key inclusion criteria (23 listed)
- Subject is ≥18 years of age
- Subjects with native coronary artery disease (including stable or unstable angina and silent ischemia) suitable for PCI
- 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)
- 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.
- 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)
Key exclusion criteria (34 listed)
- Any comorbidity or condition which may reduce compliance with this protocol, including follow-up visits
- Subject is a member of a vulnerable population including individuals with mental disability, persons in nursing homes, children, impoverished persons, persons in emergency situations, homeless persons, nomads, refugees, and those incapable of giving informed consent.
- Subject is participating in another research study involving an investigational agent (pharmaceutical, biologic, or medical device) that has not reached the primary endpoint
- Subject is pregnant or nursing (a negative pregnancy test is required for women of child-bearing potential within 7 days prior to enrollment)
- Unable to tolerate dual antiplatelet therapy (i.e., aspirin, and either clopidogrel, prasugrel, or ticagrelor) for at least 6 months
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Primary outcome
Percentage of Participants Who Experienced Freedom From MACE Within 30 Days Post-procedure
Time frame: Within 30 days of index procedure
The primary safety endpoint was freedom from major adverse cardiac events (MACE) at 30 days - a composite of cardiac death, myocardial infarction (MI) and target vessel revascularization (TVR). The primary endpoints were analyzed using the Intent To Treat (ITT) population.
Percentage of Subjects With Procedural Success
Time frame: 12-24 hours post procedure or at discharge, whichever is earlier, but at least 6 hours post procedure
The primary effectiveness endpoint was Procedural Success defined as stent delivery with a residual in-stent stenosis <50% (core laboratory assessed) and without in-hospital MACE

What does the primary outcome measure?
Percentage of Participants Who Experienced Freedom From MACE Within 30 Days Post-procedure (time frame: Within 30 days of index procedure). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04151628, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
