About this study

To observe early safety and performance of the Shockwave Medical Lithoplasty® System (specifically, Lithoplasty® Catheters: 2.5 x 60mm, 2.75 x 60mm, 3.0 x 60mm, 3.25 x 60mm, and 3.5 x 60mm) in subjects to demonstrate that the Shockwave device can safely and effectively deliver localized pulsatile mechanical energy for balloon dilation of calcified, stenotic, infrapopliteal arteries.

Read the detailed description

Shockwave Medical, Inc. intends to conduct a prospective, single-arm, multi-center, clinical study designed to evaluate the early safety and performance of the Shockwave Lithoplasty® System in subjects with moderate to heavily calcified peripheral arteries with 2.5mm to 3.5mm reference vessel diameter at the target site. The Shockwave Lithoplasty® System is indicated for lithotripsy-enhanced, low-pressure balloon dilation of calcified, stenotic peripheral arteries in patients who are candidates for percutaneous therapy. Up to twenty subjects will be enrolled and treated with Lithoplasty® System.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Shockwave Lithoplasty® SystemDevice

    The Shockwave Lithoplasty® System is a proprietary lithotripsy-enhanced balloon catheter that is designed to be delivered through the peripheral arterial system of the lower extremities to the site of calcified stenosis. Activating the lithotripsy within the device will generate pulsatile mechanical energy within the target treatment site, disrupt calcium within the lesion and allow subsequent dilation of a peripheral artery stenosis using low balloon pressure. The system consists of a balloon catheter with multiple integrated lithotripsy electrodes, and a generator.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Composite of new-onset Major Adverse Events (MAE)

    Death Myocardial infarction Need for emergency surgical revascularization of the target limb. Amputation of target limb.

    Measured: Procedure through 30 days post procedure

  2. Efficacy

    Acute reduction in percent (%) diameter stenosis of target lesion

    Measured: Peri-Procedural

Secondary outcomes (1)
  1. Procedural Success

    The ability of the Shockwave Lithoplasty® System to achieve a post-shockwave residual diameter stenosis of ≤50%

    Measured: Peri-Procedural

Questions about this trial

What is this clinical trial studying?

A study testing Shockwave Lithoplasty® System in people with Peripheral Arterial Disease, run by Shockwave Medical, Inc. at 4 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Austria, Germany, New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite of new-onset Major Adverse Events (MAE) (time frame: Procedure through 30 days post 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 NCT02911623, which also lists 1 linked publication.

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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Oct 2017; AzTrials last refreshed its copy on 8 Nov 2026.
