Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if PRT-201 when applied to a limited segment of your blood vessel (about 2 inches) immediately after surgery to create an arteriovenous fistula is safe and improves the patency of your fistula. PRT-201 is a protein that has been shown to help keep vessels open ("patent") when applied to the outside surface of the blood vessels (arteries and veins) in AVF patients in a previous study.
