Key information

About this study

This is a prospective, global, multi-center, single-blinded, 1:1 randomized clinical trial evaluating the IN.PACT™ AV Access Drug Coated Balloon (DCB) compared to percutaneous transluminal angioplasty (PTA) for treatment of subjects presenting with de novo or non-stented restenotic obstructive lesion of native arteriovenous dialysis fistulae (AVF) in the upper extremity. The trial will be conducted in up to 30 sites in the United States, Japan, and New Zealand.
