A Study of Vonapanitase (PRT-201) Administered Immediately After Radiocephalic Arteriovenous Fistula(AVF) Creation in Patients With Chronic Kidney Disease (CKD) (PATENCY-2)

Phase 3
Completed
Conditions
Chronic Kidney Disease
Interventions
Drug: Placebo
Registration Number
NCT02414841
Lead Sponsor
Proteon Therapeutics
Brief Summary

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.

Acceptable methods of birth control include abstinence, barrier methods, hormones, or intra-uterine device.
Exclusion Criteria
  1. Malignancy or treatment for malignancy within the previous 12 months with the exception of the following cancers if they have been resected: localized basal cell or squamous cell skin cancer, or any cancer in situ.
  2. Presence of any significant medical condition that might significantly confound the collection of safety and efficacy data in this study.
  3. Previous treatment with vonapanitase (PRT-201).

Number of Participants With AVF Use for HemodialysisAssessed at up to 12 Months

AVF use for hemodialysis is defined as the ability of the study AVF to be successfully cannulated and used for hemodialysis for a minimum of 90 days or at least 30 days prior to a patient's last visit, if hemodialysis has not been initiated at least 90 days prior to the patient's last visit. If AVF use is not defined as above, non-use of the AVF for hemodialysis is defined as an abandoned fistula prior to use; or if hemodialysis is recorded on 2 consecutive visits and there is no cannulation date or duration of use is less than 90 days. The patients who are not categorized as having use or non-use of the AVF have insufficient data to determine AVF use for hemodialysis and will be categorized as having indeterminate use.
