Interim Data from IMAGE-BTK Clinical Trial Presented at AMP 2022

REDWOOD CITY, CA / ACCESSWIRE / September 1, 2022 / Avinger, Inc. (NASDAQ:AVGR), a commercial-stage medical device company developing and marketing the first and only intravascular image-guided, catheter-based systems for diagnosis and treatment of vascular disease, today announced the presentation of interim data from the IMAGE-BTK clinical study for Pantheris SV at the annual AMP (Amputation Prevention Symposium) conference in August.

AMP focuses on education and technologies for treating critical limb ischemia (CLI), an advanced stage of peripheral artery disease (PAD), in patients facing a life-altering amputation. The conference features lectures by internationally recognized faculty, live case symposia, hands-on workshops, and exhibits supporting the mission of amputation prevention.

Dr. Thomas Davis, a faculty member at AMP and interventional cardiologist at Eastlake Cardiology in Michigan, highlighted the extremely promising interim results from the IMAGE-BTK clinical trial featuring Avinger technology in his presentation "IMAGE-BTK: Assessment of the Utility of the Pantheris SV System to Address Lesions Below-the-Knee." IMAGE-BTK is a post-market study designed to evaluate the safety and efficacy of Pantheris SV in treating below-the-knee lesions. In his presentation, Dr. Davis noted that below-the-knee (BTK) lesions are a major contributor to CLI, that 73% to 95% of patients with CLI will have a major amputation if not treated within one year of diagnosis, and that 24% of patients have an increased risk of mortality at one year. Furthermore, minor complications in BTK procedures can result in serious consequences, with most existing treatments exhibiting high rates of recurrence.

Dr. Davis highlighted that through the first 24 patients enrolled in IMAGE-BTK, zero complications or adverse events have occurred within 30 days of the index procedure. Importantly, even in a patient population with advanced PAD, 100% of enrollees with subsequent follow-up had freedom from target vessel restenosis (TVR) at 6 months and 93% had freedom from TVR at 12 months. Interim results have also shown patency amongst these patients at 96% after 6 months and 93% after 12 months. Patency with duplex ultrasound assessment is often considered a gold standard for effective outcomes in these types of procedures.

"This level of durability and safety for patients with advanced peripheral disease represents a significant advancement for the difficult-to-treat patient population suffering from BTK disease," commented Dr. Davis. "The unique combination of onboard image-guidance with a targeted plaque removal mechanism in Pantheris SV allows me to create unparalleled luminal gain during the intervention, without causing damage to healthy vessel structures or creating other complications. With the initial enrollees in IMAGE-BTK, we have seen a 90% reduction in percent stenosis of lesions treated without any major adverse events. Should these outcomes continue, Pantheris SV could become a new standard of care for patients with BTK disease and CLI."

Jeff Soinski, Avinger's President and CEO, noted, "These interim findings from IMAGE-BTK validate the clinical results we have monitored in the field since we launched Pantheris SV. We look forward to completing enrollment of this study and publishing the outcomes in a peer-reviewed publication, as we believe Pantheris SV can benefit a wide population of patients suffering from PAD. The AMP conference, as one of the preeminent platforms for advancing the treatment of clinical limb ischemia and amputation prevention, represents an impactful stage to share these powerful early outcomes."

Atherectomy is a minimally invasive treatment for PAD in which a catheter-based device is used to remove plaque from a blood vessel. Avinger's Lumivascular technology incorporates an onboard image-guidance system to allow physicians, for the first time ever, to see inside the artery during an atherectomy or CTO-crossing procedure by using an imaging modality called optical coherence tomography, or OCT. During the procedure, high-resolution intravascular OCT images are displayed on Avinger's Lightbox console in real-time to guide therapy. Physicians performing therapeutic procedures with other devices must rely solely on X-ray images and tactile feedback to guide their interventions while treating complicated arterial disease. With the Lumivascular approach, physicians can more accurately navigate their devices and treat PAD lesions to deliver safe and effective outcomes, without exposing healthcare workers and patients to the negative effects of ionizing radiation.

About Avinger, Inc.
Avinger is a commercial-stage medical device company that designs and develops the first and only image-guided, catheter-based system for the diagnosis and treatment of patients with Peripheral Artery Disease (PAD). PAD is estimated to affect over 12 million people in the U.S. and over 200 million worldwide. Avinger is dedicated to radically changing the way vascular disease is treated through its Lumivascular platform, which currently consists of the Lightbox series of imaging consoles, the Ocelot and Tigereye™ family of chronic total occlusion (CTO) catheters, and the Pantheris® family of atherectomy devices. Avinger is based in Redwood City, California. For more information, please visit www.avinger.com.
