  Purpose
PRT-201 is a recombinant human type-I pancreatic elastase intended for local, long-lasting dilation of the AVG venous anastomosis and outflow vein. The goal of the treatment is to improve primary patency and long-term survival of AVGs and thereby provide patients with chronic kidney disease (CKD) a reliable and durable vascular access site for hemodialysis. Recent data indicate that up to three quarters of patients have loss of graft patency at one year, indicating a substantial need for new therapies. This clinical trial will explore the safety and dilatory effect of topically administered PRT-201 on the outflow vein of a newly placed upper extremity AVG.
