Results Complement Ongoing Phase 1 Clinical Study
WALTHAM, Mass., Jan. 8, 2015 (GLOBE NEWSWIRE) -- Proteon Therapeutics Inc. (Nasdaq:PRTO), a company developing novel, first-in-class pharmaceuticals to address the medical needs of patients with kidney and vascular diseases, today announced publication of nonclinical data on PRT-201 (vonapanitase) in peripheral artery disease (PAD). This ex vivo study evaluated the effect of a single treatment of PRT-201, an investigational drug, on atherosclerotic human arteries. The positive results, published in the December issue of the Journal of Cardiovascular Pharmacology, support Proteon's clinical development program in PAD. Proteon's Senior Vice President and Chief Medical Officer, Steven Burke, M.D., is the senior author of the published manuscript. Click here to access the entire article.
'These data published in the Journal of Cardiovascular Pharmacology support our belief that PRT-201 may have multiple surgical and endovascular applications in addition to our lead application in hemodialysis vascular access,' said Timothy Noyes, President and Chief Executive Officer of Proteon. 'We now look forward to the results of our Phase 1 study evaluating endovascular treatment with PRT-201 for patients suffering from PAD, which we expect in the second half of 2015.'
PRT-201 has the potential to treat patients suffering from a number of renal or vascular diseases for which there currently are limited therapeutic options, including PAD. The results published in the Journal of Cardiovascular Pharmacology support Proteon's ongoing Phase 1 clinical study of PRT-201, which enrolled patients with symptomatic PAD of the superficial femoral or popliteal artery. Immediately following angioplasty, patients received PRT-201 delivered to the arterial wall via a catheter-based approach using the Mercator MedSystems Bullfrog® Micro-Infusion Device.
Proteon's lead clinical program is evaluating whether PRT-201 can prolong the patency and reduce the failure of hemodialysis vascular access in patients with chronic kidney disease (CKD). Proteon is currently conducting a Phase 3 multicenter, randomized, double-blind, placebo-controlled 300-patient clinical study of PRT-201 in CKD patients undergoing surgical placement of an arteriovenous fistula (AVF) for hemodialysis vascular access. The Phase 3 study follows the completion of a Phase 2 multicenter, randomized, double-blind, placebo-controlled clinical study in which 151 patients were treated.
About Peripheral Arterial Disease
Peripheral artery disease (PAD) is characterized by atherosclerosis in the arteries of the legs, which leads to poor blood flow. Patients with PAD may experience muscle pain during walking, suffer from ulcers that are slow to heal or, in the most severe cases, require amputation. PAD affects eight million Americans and is a significant cause of both morbidity and mortality (source: American Heart Association).
About PRT-201
PRT-201 (vonapanitase) is an investigational recombinant human elastase that is being studied for its ability to improve outcomes in patients suffering from vascular disease. Elastase has been shown in preclinical settings to reduce neointimal hyperplasia formation, which may result in improved blood flow and prolonged vessel patency. PRT-201 has received fast track and orphan drug designations from the U.S. Food and Drug Administration (FDA) and orphan medicinal product designation from the European Commission for hemodialysis vascular access indications.
