|Proteon Therapeutics to Present at Upcoming ERA-EDTA Annual Congress|
A functioning AVF, which is a surgically created connection between an artery and a vein, is a hemodialysis patient's lifeline, enabling the patient to undergo life-sustaining hemodialysis. AVFs are susceptible to patency loss, which occurs when an AVF has insufficient blood flow for hemodialysis, most often due to a blockage in the blood vessels of the AVF. Patency loss can result in additional surgical or other corrective procedures, such as balloon angioplasty, and reduced AVF survival.
Proteon is currently enrolling patients in a Phase 3 multicenter, randomized, double-blind, placebo-controlled clinical study of vonapanitase in chronic kidney disease (CKD) patients undergoing surgical creation of a radiocephalic AVF for hemodialysis. The Company expects to complete enrollment by the end of 2015 and is anticipating initiating enrollment in a second Phase 3 clinical study in the second quarter of 2015. Proteon is also conducting an ongoing Phase 1 clinical study of vonapanitase in patients with symptomatic peripheral artery disease (PAD).
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 require hemodialysis and need a high-flow vascular access to repeatedly connect the patient's bloodstream to a hemodialysis machine for this life-saving, chronic treatment. Three times per week for three to four hours each session, blood is pumped from the body and passed through a dialysis machine that removes waste and excess water normally excreted by the kidneys. The preferred form of vascular access, used by two-thirds of hemodialysis patients in
Vonapanitase (formerly PRT-201) is an investigational drug designed to improve arteriovenous fistula (AVF) patency, the period of time during which an AVF remains open with adequate blood flow to enable hemodialysis. Vonapanitase is applied in a single administration and is currently being studied in a Phase 3 clinical trial in patients with chronic kidney disease (CKD) undergoing surgical creation of a radiocephalic AVF for hemodialysis. Vonapanitase has received fast track and orphan drug designations from the

These statements, including those regarding the potential surgical and endovascular applications for vonapanitase, the potential use of vonapanitase for patients with renal and vascular diseases, the effect of vonapanitase in patients with CKD, timing to complete enrollment for the Phase 3 trial, timing for initiation of enrollment for the second Phase 3 trial, and those relating to future events or our future financial performance or condition, involve substantial known and unknown risks, uncertainties and other important factors that may cause our actual results, levels of activity, performance or achievements to differ materially from those expressed or implied by these forward-looking statements. These risks, uncertainties and other factors, including whether our cash resources will be sufficient to fund our operating expenses and capital expenditure requirements for the period anticipated; whether data from early clinical trials will be indicative of the data that will be obtained from future clinical trials; whether vonapanitase will advance through the clinical trial process on the anticipated timeline and warrant submission for regulatory approval; whether such a submission would receive approval from the
