CONNECT-AV Trial for Endovascular AV Fistula Treatment Begins Patient Enrollment

By News Release

Patient enrollment has begun and the first patients have been treated in the post-market surveillance study, CONNECT-AV, of Becton, Dickinson and Company’s (BD) WavelinQ EndoAVF System. CONNECT-AV is a prospective, single-arm, open-label study that will follow patients treated with the system for 24 months.

The study's dual primary effectiveness endpoints are the percentage of subjects dialyzing using successful 2-needle cannulation for at least 75% of the dialysis sessions over a continuous 28-day period at 6 months, and the subjects maintaining primary patency at 6 months.

The primary safety endpoint is freedom from device and procedure-related serious adverse events through 30 days. The trial is expected to enroll 280 participants in the United States.

"For more than 50 years, medicine has looked for a next generation hemodialysis access procedure for patients with ESKD that can truly change the treatment paradigm," said Brandon Repko, MD, Medical Director of Nuclear Imaging and Therapeutic Services at Butler Memorial Hospital in Butler, Pennsylvania, who treated the first patient in the CONNECT-AV trial in March 2021. "The CONNECT-AV trial is the next step in proving WavelinQ EndoAVF System's role in 21st century AV fistula creation. My colleagues and I are thrilled to be a part of that patient care evolution."

CONNECT-AV is one of two post-market studies of the WavelinQ EndoAVF System. The second study, WAVE-Global is a prospective, single-arm, open-label study that will follow patients treated with the WavelinQ EndoAVF System for 24 months.

The WAVE-Global primary endpoints are the number of interventions needed post creation to facilitate and/or maintain AV fistula use at 6 months, and the proportion of participants with freedom from Clinical Events Committee adjudicated device- or procedure-related serious adverse events at 30 days. The trial is expected to enroll 150 participants globally (outside of the US).

"Physicians already have real-world experience using the WavelinQ EndoAVF System to create AV fistulas that make life-preserving hemodialysis possible," said Panagiotis M. Kitrou MD, MSc, PhD, EBIR, FCIRSE, Asst. Professor in Interventional Radiology, Patras University Hospital, Greece and a principal investigator in the WAVE-Global study. "Both of these studies will provide important long-term data on the safety and effectiveness of WavelinQ EndoAVF System to help make informed decisions about patient care."

The first patient in the WAVE-Global trial was treated by Dr. Kitrou in December 2020 at Patras University Hospital.

Globally, there are approximately 3 million patients on hemodialysis with the majority depending on an AV fistula as their lifeline for hemodialysis therapy1. The WavelinQ EndoAVF System is designed to give healthcare providers a versatile endovascular AV fistula creation alternative to open surgery. It uses two thin, flexible, magnetic catheters and a burst of RF energy to create an endovascular AV fistula.

Using the WavelinQ EndoAVF System gives physicians a minimally invasive option for creating an AV fistula for patients who need hemodialysis to survive. The system's 4F, low profile increases anatomical fistula location options and enables additional venous wrist access points (ulnar vein or radial vein), providing increased procedural flexibility for physicians, while helping to reduce risk of scarring or arm disfigurement for patients compared to open surgical AV fistula creation.

"WavelinQ EndoAVF System represents a major advancement in AV fistula creation and offers physicians and their patients an innovative and minimally invasive alternative to surgical AV fistula creation, which can be associated with scarring and vessel trauma," said J.D. Meler, MD, Vice President of Medical and Clinical Affairs for BD's Peripheral Intervention business. "As innovators in this space, the CONNECT-AV and WAVE-Global Studies are part of our ongoing effort to add data to help inform physicians, payors and regulators about the value and utility of the WavelinQ EndoAVF System and how it may benefit patients who require hemodialysis."
