About this trial

This is an interventional treatment trial for End Stage Renal Disease

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Subjects older than 18 years with end-stage renal disease (ESRD) who are not, or who are no longer, candidates for creation of an autogenous AV fistula, and therefore require placement of an AV graft in the upper extremity to start or maintain hemodialysis therapy
  • Suitable anatomy for the implantation of an aXess graft
  • The patient has been informed about the nature of the study, agrees to its provisions, and has provided written informed consent
  • The patient has been informed and agrees to pre- and post- procedure follow up
  • Life expectancy of at least 12 months

Exclusion Criteria:

  • History or evidence of severe cardiac disease (NHYA Functional Class IV and/or EF <30%), myocardial infarction within six months of study entry, ventricular tachyarrhythmias requiring continuing treatment, or unstable angina
  • Stroke within six months before study entry
  • Active clinically significant autoimmune / inflammatory disease, immunodeficiency (including AIDS / HIV), use of immunosuppressive therapy or medication that likely interferes with restorative therapies
  • Abnormal blood values (e.g. leurkopenia with white blood cell (WBC) count < 4,000/mm3 and/or anemia with hemoglobin <8g/dL and/or thrombocytopenia < 100,000/mm3) that could influence patient recovery and/or graft hemostasis
  • Any active local or systemic infection (WBC > 15,000/mm3)
  • Uncontrolled or poorly controlled diabetes (hemoglovin A1c > 8% despite standard care) or hospitalization for poor glucose control within the previous 6 months
  • Reduced liver function, defined as: >2x the upper limit of normal for serum bilirubin, aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase; International Normalized Ratio (INR) > 1.5 or prothrombin time (PT) > 18 seconds
  • Known heparin-induced thrombocytopenia
  • Active bleeding disorder and/or any coagulopathy or thrombo embolic disease
  • History or evidence of severe peripheral vascular disease in the upper limbs
  • Known or suspected central vein obstruction on the side of planned graft implantation
  • Previous dialysis access graft in the operative limb unless the aXess graft can be placed more proximally than the previous failed graft
  • More than 1 failed dialysis access graft in the operative limb
  • Anticipated renal transplant within 6 months
  • Subjects receiving a forearm graft which crosses the elbow
  • Allergies to study device (Nitinol) or agents/medication, such as contrast agents, aspirin, or clopidogrel, that cant be controlled medically
  • Pregnant or breastfeeding woman or woman in fertile period not taking adequate contraceptives
  • Subject is participating in another study
  • Previous enrollment in this study
  • Any other condition which, in the judgement of the investigator would preclude adequate evaluation for the safety and efficacy of the study conduit

5. Study Description

Brief Summary
A feasibility study is to assess the preliminary safety and performance of the Xeltis hemodialysis access (aXess) graft.
Detailed Description
A prospective, single arm, non-randomized FIH feasibility study to evaluate the preliminary safety and performance of the Xeltis hemodialysis access graft in subjects older than 18 years with end-stage renal disease, who plan to undergo hemodialysis for at least the first 6 months after study access creation, and are deemed not suitable for fistula creation by the operating surgeon.
