New graft could make dialysis easier for kidney patients
NCT ID NCT07555717
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new type of artificial blood vessel (STARgraft) for people with end-stage kidney disease who need dialysis. The graft is placed in the arm to help connect the patient to the dialysis machine. The goal is to see if it works better than standard grafts at keeping blood flow steady and avoiding problems. About 20 adults will take part, and the study will follow them for up to 36 months.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Adult patients, 18 years or older. 2. Patient has given informed consent to participate in the trial. 3. Stated willingness to comply with all trial procedures and availability for the duration of the trial. 4. Able to effectively communicate with trial personnel. 5. Indicated patient population (end stage renal disease). 6. Candidate for a new AV graft placed in the upper arm and judged to need dialysis within 2 months. Patient may have a failed access at a different anatomical location. 7. Life expectancy judged to be at least 2 years with consideration of patient frailty. 8. Axillary vein approximately 7 mm in diameter or greater. 9. Brachial artery approximately 4 mm in diameter or greater. 10. Acceptable cardiac risk level (cardiac output ≥ 3.5 l/min, pulmonary artery pressure ≤ 50 mmHg, and ejection fraction ≥ 40%). 11. Systolic blood pressure equal to or greater than 120 mmHg. 12. Absence of central venous stenosis downstream from implant site confirmed with ultrasound and/or venogram. Exclusion Criteria: 1. Unable or unlikely to comply with trial protocol and/or follow-up. 2. Pregnancy. 3. Previous history of Peritoneal Dialysis treatment within the last 2 months 4. Central venous catheter located on same side as intended implant location. 5. Clinical morbid obesity (BMI \> 40). 6. Anatomical limitations, including issues discovered intraoperatively during vessel exposure. 7. Immunodeficiency syndrome. 8. History of hypercoagulation or bleeding disorders. 9. Elevated platelet count \> 1 million per microliter of blood. 10. History of heparin-induced thrombocytopenia syndrome 11. Medically confirmed stenosis or compromised valves in the veins downstream of the implant site. 12. Inadequate arterial flow or pressure proximal to the implant site. 13. Currently participating in another investigational drug or device trial which may clinically interfere with any endpoints of this trial. 14. Fever greater than 38°C. 15. Known allergic reaction to silicone, or untreatable allergy to imaging contrast materials. 16. Confirmed or suspected bacterial, viral or parasitic infection within 8 weeks prior to graft implant, or ongoing symptoms. 17. Uncontrolled or poorly controlled diabetes. 18. History or evidence of severe cardiac disease. 19. Any other condition which, in the judgment of the Investigator, would preclude adequate evaluation or impact patient safety or trial conduct.
