Study summary

The goal of this clinical trial is to learn if the Auryon Atherectomy System with balloon angioplasty safe and effective in treating lower limb blockages. The main question it aims to answer is: Is treatment with Auryon Atherectomy System more effective than angioplasty alone in preventing death, amputation, revascularization and improving patency? Researchers will compare the Auryon Atherectomy System with balloon angioplasty to balloon angioplasty alone.

Angiographic Inclusion Criteria

  • Target lesion that is located in a native, de novo infra-popliteal artery (extending from P3 of the popliteal artery to the margin of the ankle mortise).

  • Subject is participating in another research study involving an agent (pharmaceutical, biologic, or medical device) that has not reached the primary endpoint.
  • Subject has other medical, social or psychological problems that, in the opinion of the investigator, preclude them from receiving this treatment, and the study requirements and evaluations pre- and post-treatment.

Angiographic Exclusion Criteria

  • Subject is already enrolled in other investigational (interventional) studies that would interfere with study endpoints.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
