Proteon Therapeutics Announces Two Presentations at the American Society of Diagnostic and Interventional Nephrology Meeting
Review results of PATENCY-1, the Phase 3 trial of investigational vonapanitase
Data on impact of fistula outcomes on
The presentation of Phase 3 results titled, “PATENCY-1: Phase 3 Outcomes of Vonapanitase on Radiocephalic AVF Outcomes,” will be given by
Proteon previously announced results from the PATENCY-1 clinical trial with investigational vonapanitase. Vonapanitase-treated patients had a 17% reduction in the risk of primary unassisted patency loss over one year compared to placebo, although the difference was not statistically significant (p=0.254), and a 34% reduction in the risk of secondary patency loss (fistula abandonment) compared to placebo (p=0.048). Unassisted use of the fistula for hemodialysis, a tertiary endpoint in PATENCY-1, was higher in vonapanitase-treated patients compared to placebo (p=0.035). PATENCY-1 evaluated a single administration of investigational vonapanitase in patients with chronic kidney disease receiving or expecting to receive hemodialysis who underwent surgical creation of a radiocephalic arteriovenous fistula.
Additionally at ASDIN, new data on the impact of fistula outcomes on
This presentation will include an analysis of
“Vascular access failures lead to increased morbidity and mortality, and this ground-breaking analysis of fistula-related costs clearly demonstrates the burden that access failures place on the healthcare system,” stated
About Chronic Kidney Disease, Hemodialysis and Vascular Access
In the most severe stage of chronic kidney disease (CKD), also known as kidney failure, the kidneys can no longer function to sustain life. The majority of patients with kidney failure undergo chronic hemodialysis, which requires a high-flow vascular access to repeatedly connect the patient’s bloodstream to a hemodialysis machine for this life-saving treatment. The preferred form of vascular access for hemodialysis is a radiocephalic arteriovenous fistula, created when a surgeon connects a vein to an artery in the forearm, resulting in a substantial increase in blood flow and vein dilation.
Vonapanitase is an investigational drug intended to improve hemodialysis vascular access outcomes. Vonapanitase is applied in a single administration and is currently being studied in a Phase 3 trial in patients with CKD undergoing surgical creation of a radiocephalic arteriovenous fistula for hemodialysis. Vonapanitase has received fast track and orphan drug designations from the
Proteon Therapeutics is committed to improving the health of patients with kidney and vascular diseases through the development of novel, first-in-class therapeutics. Proteon's lead product candidate, vonapanitase, is an investigational drug intended to improve hemodialysis vascular access outcomes. Proteon is currently enrolling patients in a Phase 3 clinical trial, PATENCY-2. Proteon is also evaluating vonapanitase in Phase 1 clinical trials in patients with peripheral artery disease (PAD).
