Intra-operative exclusion criteria:

Terms in these criteria, in plain language(6)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Study arms

  • Experimental
    XPAD

    Device: XPAD conduit

Interventions

  • DeviceXPAD conduit

    The XPAD bypass conduit is a sterile, restorative biodegradable polymer-based vascular conduit, consisting of a tubular structure with a 33cm length and 6mm inner diameter. It is comprised of a highly porous polymer matrix and an embedded electropolished nitinol reinforcement layer (Strain Relief System). The XPAD conduit is in a straight configuration and may be implanted in the lower limb for elective bypass surgery.

What researchers measure

Primary outcomes

  1. Primary patency rate

    Primary patency defined as the interval between conduit implantation and the first intervention to maintain or restore patency

    Time frame: 12 months post-implant

  2. Freedom from device-related SAE

    Time frame: Day 1, 30 days, 6 months, and 12 months post-implant

Secondary outcomes

  1. Implantation success rate

    Implantation success defined as a technically successful XPAD conduit implantation in the planned configuration, free from kinking and tension in the anastomoses, and a patent XPAD conduit at the moment of discharge.

    Time frame: Day 1

  2. Freedom from Major Bleeding events

    Major Bleeding defined as type 3, 4 or 5 bleeding according to the Bleeding Academic Research Consortium (BARC) classifications

    Time frame: Day 1, 30 days and 6 months post-implant

  3. Patency (primary, primary assisted, and secondary) rates

    Primary patency defined as the interval between conduit implantation and the first intervention to maintain or restore patency. Assisted primary patency defined as the interval between conduit implantation and the first occlusion (thrombosis), including interventions (operative or endovascular) aimed to maintain the functionality the conduit. Secondary patency defined as the interval between conduit implantation and abandonment with or without interventions (operative or endovascular) aimed to maintain the functionality the conduit, including occurrence of a censored event (death, change of modality, loss of follow-up).

    Time frame: 6, 12, 24, 36, 48 and 60 months post-implant

  4. Freedom from device-related SAE

    Time frame: 24, 36, 48 and 60 months post-implant

  5. Rate of wound/conduit infections

    Time frame: 30 days, 6, 12, 24, 36, 48 and 60 months post-implant

  6. Freedom from Major Amputations

    Major Amputation defined as any amputation that results in limb shortening

    Time frame: 30 days, 6, 12, 24, 36, 48, and 60 months post-implant

  7. Freedom from all-cause mortality

    Time frame: 30 days, 6, 12, 24, 36, 48, and 60 months post-implant

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Dec 2026; primary completion for Dec 2028, 24 months later.

Of 125 industry-sponsored interventional studies with no phase under Peripheral Arterial Disease, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 45. This study's planned 24 months is below that.

Counting every sponsor, half of 385 studies reached it within 31 months; a quarter within 17 and three quarters within 55.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
