6-Month Data From the Surmodics Avess™ AV Fistula DCB First-in-Human Study Presented at VIVA 2020

Study finds 100 percent target lesion patency at 30 days; 90.9 percent of patients free from revascularization at 6 months

Surmodics, Inc. (NASDAQ:SRDX), a leading provider of medical device and in vitro diagnostic technologies to the health care industry, today announced that 6-month data from the AVESS first-in-human (FIH) study of the company’s Avess™ AV Fistula drug-coated balloon (DCB) was shared during a morning session at the Vascular Interventional Advances (VIVA) 2020 virtual conference.

The AVESS study is a prospective, multi-center, single-arm study to assess the safety and performance of the Avess DCB when used in the treatment of subjects with obstructive lesions of arteriovenous fistulae (AVF) for hemodialysis.

Six-month data from the study show that target lesion patency at 30 days and 6 months was 100 percent and 90.9 percent, respectively. A single re-intervention was required within 6 months, with no AVFs thrombosed. The study’s primary safety endpoints reported no mortality and no device or procedure related adverse events at 30 days, and all patients maintained functional AVFs for hemodialysis.

"This first-in-human study demonstrates that the Avess DCB is a safe and promising treatment for AV fistula stenosis, which can lead to vascular access dysfunction, thrombosis and loss," said Ramon L. Varcoe, MD, MBBS, MS, FRFRACS, PhD, associate professor of vascular surgery at Prince of Wales Hospital (Sydney, New South Wales, Australia) and co-lead investigator for the AVESS FIH clinical study.

"Previous AV fistula studies have demonstrated that DCBs effectively reduce rates of restenosis after percutaneous angioplasty," added Andrew Holden, MD, MBChB, FRANZCR, EBIR, ONZM, Associate Professor, Director of Interventional Radiology at Auckland City Hospital (Auckland, New Zealand) and co-lead investigator for the AVESS FIH clinical trial. "The Avess DCB is a next-generation DCB that may provide further clinical benefits while minimizing systemic paclitaxel exposure."

Data presented include 6-month results from 12 patients treated with an Avess DCB between December 2018 and August 2019. The majority of AVFs were radiocephalic (10/12, 83.3 percent) with the stenosis located in the juxta-anastomosis (7/12, 58.3 percent), cannulation zone (2/12, 16.7 percent) and outflow (3/12, 25 percent). All patients completed follow-up at or beyond 6 months.

"Our goal with all of our DCB platforms has been to advance the technology to improve drug transfer and distribution effect on the arterial wall offering the opportunity to use a lower drug dose," said Gary Maharaj, president and CEO of Surmodics. "We are quite pleased with the AVESS first-in-human study results, which provide vital safety data on the Avess DCB and directional data on its effectiveness. This FIH data strengthens our believe that the Avess DCB could be a safe and promising treatment that improves patient outcomes while reducing the number of interventions needed to maintain patency."

About the Avess DCB

The design of the Avess DCB reflects Surmodics’ long-standing industry leadership in the development of surface technology for vascular medical devices. The device includes a proprietary drug-excipient formulation for the balloon coating and is manufactured using a proprietary process to improve coating uniformity. Pre-clinical data have shown a three to five times higher target tissue drug concentration, a more evenly distributed and durable drug effect, and lower incidence of downstream drug concentrations compared to control DCBs.1 The Avess DCB is an investigational device, limited by United States law to investigational use.
