Condition chronic kidney disease
Treatments prt-201, placebo
Phase phase 3
Sponsor Proteon Therapeutics
Start date July 2014
End date December 2016
Trial size 300 participants
Trial identifier NCT02110901, PRT-201-310


This research study is designed to assess the safety and effectiveness of an experimental drug called PRT-201 in patients both receiving or expecting to receive dialysis who have chronic kidney disease and who are undergoing surgery to create a new access point to their bloodstream for hemodialysis. PRT-201 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 PRT-201 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.

Study Design

Allocation randomized
Intervention model parallel assignment
Primary purpose treatment
Masking participant, care provider, investigator, outcomes assessor
(Active Comparator)
PRT-201 administered at the time of radiocephalic fistula creation
(Placebo Comparator)
Placebo administered at the time of radiocephalic fistula creation. The placebo is identical in appearance and composition to PRT-201 but lacks the active ingredient.

Primary Outcomes

AVF primary unassisted patency
time frame: 12 months after AVF creation

Secondary Outcomes

Secondary AVF patency
time frame: 12 months after AVF creation

Eligibility Criteria

All participants from 18 years up to 100 years old.

Inclusion Criteria: 1. Age of at least 18 years. 2. Life expectancy of at least 6 months. 3. Diagnosis of Chronic Kidney Disease (CKD). 4. Planned creation of a new radiocephalic arteriovenous fistula (AVF)-revision of an existing AVF is not eligible. 5. Ability to understand and comply with the requirements of the entire study and to communicate with the study team. 6. Written informed consent using a document that has been approved by the Institutional Review Board (IRB). 7. If female and of childbearing potential (premenopausal and not surgically sterile) must have a negative serum pregnancy test at the screening visit (Visit 1) and be willing to use contraception from the time of the screening visit to 2 weeks following study drug administration. 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 PRT 201. 4. Treatment with any investigational drug within the previous 30 days or investigational antibody therapy within the previous 90 days prior to signing informed consent.
