Condition arteriovenous graft
Treatments srm003, participating site's standard practice
Phase phase 2
Sponsor Shire
Start date March 2013
End date October 2014
Trial size 200 participants
Trial identifier NCT01806584, AVG01-SRM003


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.

Study Design

Allocation randomized
Endpoint classification safety/efficacy study
Intervention model parallel assignment
Masking single blind (subject)
Primary purpose treatment
(Active Comparator)
srm003 Allogeneic human aortic endothelial cells cultured in a gelatin matrix (Gelfoam®).
One time implant (3 SRM003 pieces) on surgery day.

Primary Outcomes

Compare the duration of assisted primary and secondary patency for arteriovenous grafts treated with SRM003 with those treated with participating sites' standard practice.
time frame: Up to 78 weeks

Secondary Outcomes

Compare the incidence of AVG-related thrombosis and/or access site infection within the first 6 weeks after surgery for AVGs treated with SRM003 with that for AVGs randomized to participating sites' standard practice.
time frame: Up to 78 weeks

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: 1. Subject must be 18 years of age or older at the time of signing and dating informed consent (no upper age limit), can be male or female. 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 4. Subject has a known allergy to bovine/porcine products or collagen/gelatin products. 5. Subject has a history of intravenous drug use within 6 months prior to screening 6. Subject is morbidly obese, defined as having a body mass index >40. 7. Pregnant or nursing woman, or plans to become pregnant during the study.
