Shire

Status and phase: Terminated; Phase 2

Conditions: Arteriovenous Graft

Treatments: Other: Participating Site's standard practice; Biological: SRM003

Study type: Interventional

Funder types: Industry

Identifiers

NCT01806584

AVG01-SRM003

Details and patient eligibility

About

A study to evaluate the efficacy of SRM003 treatment versus participating sites' standard practice treatment in extending the duration of primary patency after arteriovenous graft surgery in subjects with end-stage renal disease.

It is hypothesized that when placed outside the blood vessel, the seeded SRM003 gelatin matrix containing endothelial cells can provide a continuous supply of multiple growth regulatory compounds to the underlying cells within the blood vessel, while being protected from the effects of blood flow in the vessel(s) or complications resulting from being in direct contact with the point of injury.

Enrollment: 32 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

2. Subject who is of child bearing potential must agree to use adequate contraception for 6 months after randomization.
3. Subject must be currently undergoing hemodialysis or anticipating the start of hemodialysis and must require a new permanent prosthetic expanded polytetrafluoroethylene AVG placed in the upper extremity.
4. Subject must have a life expectancy of at least 78 weeks after randomization.
5. Subject must be able to understand and be willing to complete all study requirements.

Exclusion criteria

1. Subject is currently on an active organ transplant list from a deceased donor or is undergoing assessment and expects to be placed on the active organ or bone marrow transplant list within the next 78 weeks from surgery, or expects to receive a living donor organ or bone marrow within the next 78 weeks and is unwilling to change transplant list status to "hold" for 3 months after randomization.
2. Subject has had more than 3 access placement surgeries (defined as a new access, not a revision) in the target limb.
3. Subject has medical conditions and diseases that may cause non-compliance with the protocol
