NCT ID NCT06329310

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial is testing a new type of vascular graft called aXess-E for people with end-stage renal disease who need hemodialysis. The graft is made from a biodegradable polymer that is designed to be replaced by the body's own tissue over time. The study will check whether the graft is safe and works well for dialysis access in about 20 adults.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
aXess-E conduit, a biodegradable polymer-based vascular graft with nitinol reinforcement for hemodialysis access
What this could lead to
If successful, this could provide a new, regenerative option for hemodialysis access that may reduce complications compared to traditional grafts.
What could go wrong
This is an early feasibility study with only 20 participants, so results may not generalize. Risks include device-related serious adverse events such as infection, thrombosis, or graft failure.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2024

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Subjects with end-stage renal disease (ESRD) who require placement of an Arteriovenous Graft (AVG) in the upper extremity to start or maintain hemodialysis therapy 2. At least 18 years of age at screening 3. Suitable anatomy (e.g. a target vein with a minimum diameter of 5mm) for the implantation of an aXess-E conduit 4. The patient has been informed about the nature of the study, understands and agrees to its provisions, and has personally provided written informed consent 5. The patient has been informed and agrees to pre- and post- procedure follow-up 6. Life expectancy of at least 12 months Exclusion Criteria: 1. History or evidence of severe cardiac disease (New York Heart Association (NYHA) Functional Class IV and/or Ejection Fraction (EF) \<25%), myocardial infarction within six months of study enrolment, ventricular tachyarrhythmias requiring continuing treatment, or unstable angina 2. Uncontrolled or poorly controlled diabetes 3. Abnormal blood values that could influence patient recovery and or/ conduit hemostasis 4. Reduced liver function, defined as: \>2x the upper limit of normal for serum bilirubin, International Normalized Ratio (INR) \>1.5 or prothrombin time (PT) \>18 seconds 5. Any active local or systemic infection 6. Known heparin-induced thrombocytopenia 7. Known active bleeding disorder and/or any coagulopathy or thromboembolic disease 8. Allergies to study device (nitinol) or agents/medication, such as contrast agents or aspirin, that can't be controlled medically 9. Anticipated renal transplant within 6 months 10. Known or suspected central vein obstruction on the side of planned conduit implantation 11. Previous dialysis access conduit in the operative limb unless the aXess-E conduit can be placed more proximally than the previous failed conduit 12. Previous enrolment in this study 13. Subject is participating in another study 14. Pregnant or breastfeeding woman or woman in fertile period not taking adequate contraceptives 15. Any other condition which, in the judgement of the investigator would preclude adequate evaluation for the safety and performance of the study conduit Intra-operative exclusion criteria: 1\. Unsuitable anatomy to implant the aXess-E conduit (e.g. target vein and/or artery diameter smaller than anticipated; severe calcification)
