Brief Summary
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.

Official Title
A Phase 2, Single-blind, Randomized, Controlled, Multi-center Study to Evaluate the Efficacy and Safety of SRM003 (Vascugel®) in the Treatment of Subjects With Vascular Injury Resulting From Arteriovenous Graft Surgery for Hemodialysis Access
Primary Outcomes
Outcome Description
Unassisted primary patency (intervention--free access survival) was defined as the duration of time in days from the date of randomization (arteriovenous graft \[AVG\] placement) until the first date of (a) any intervention designed to establish, maintain, or restore patency, (b) occlusion (commonly due to thrombosis), or (c) access abandonment. Assessment of AVG patency was evaluated during physical examination of the subject's AVG at each visit and through ongoing AVG monitoring and surveillance according to each participating site's standard practice. It was recommended to follow the National Kidney Foundation Kidney guidelines (National Kidney Foundation 2006) on appropriate management and treatment of AVG complications to improve the function and longevity of the vascular access.
Outcome Measure
Percentage of Participants With Loss of Unassisted Primary Patency
Outcome Time Frame
Up to 78 weeks after surgery
Secondary Outcomes
Outcome Description
Assisted primary patency (thrombosis--free access survival) was defined as the duration of time in days from the date of randomization (AVG placement) until the first date of (a) occlusion (commonly due to thrombosis) or (b) access abandonment. Assessment of AVG patency was evaluated during physical examination of the subject's AVG at each visit and through ongoing AVG monitoring and surveillance according to each participating site's standard practice. It was recommended to follow the National Kidney Foundation Kidney guidelines (National Kidney Foundation 2006) on appropriate management and treatment of AVG complications to improve the function and longevity of the vascular access.
Outcome Time Frame

Outcome Description
Secondary patency (access survival until abandonment) was defined as the duration of time in days from the date of randomization (AVG placement) until the date of access abandonment. Assessment of AVG patency was evaluated during physical examination of the subject's AVG at each visit and through ongoing AVG monitoring and surveillance according to each participating site's standard practice. It was recommended to follow the National Kidney Foundation Kidney guidelines (National Kidney Foundation 2006) on appropriate management and treatment of AVG complications to improve the function and longevity of the vascular access.
