Official title

Multicenter, Double Blind, Placebo Controlled Study of Vonapanitase (PRT- 201) Administered Immediately After Radiocephalic Arteriovenous Fistula Creation in Patients With Chronic Kidney Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This research study is designed to assess the safety and effectiveness of an experimental drug called vonapanitase (PRT-201) in patients both receiving or expecting to receive hemodialysis who have chronic kidney disease and who are undergoing surgery to create a new access point to their bloodstream for hemodialysis. Vonapanitase is a protein that has been shown in previous research studies to help keep vessels patent when applied to the outside surface of the blood vessels (arteries and veins) in patients who undergo surgery to create an arteriovenous fistula (AVF). The purpose of this study is to determine whether vonapanitase when applied to a limited segment of your blood vessel (about 2 inches) immediately after surgery is safe and improves the patency of your AVF.
