Details and patient eligibility

About

A feasibility study is to assess the preliminary safety and performance of the Xeltis hemodialysis access (aXess) graft.

Full 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.

Enrollment

20 patients

Sex

All

Ages

18+ years old

Volunteers

No 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
