Avinger Announces First Patients Enrolled in Post-Market Study Comparing Pantheris OCT Imaging to Intravascular Ultrasound

Avinger, Inc. (AVGR), a leading developer of innovative treatments for peripheral artery disease (PAD), today announced the initiation of the SCAN study, a post-market study comparing optical coherence tomography (OCT) with intravascular ultrasound (IVUS) as a diagnostic imaging tool in the peripheral arteries. OCT is a light-based, high definition imaging modality, which generates no X-ray radiation. Avinger’s proprietary Lumivascular technology utilizes OCT to provide real-time intravascular imaging during the treatment of peripheral artery disease. The Company’s Pantheris image-guided atherectomy and Ocelot image-guided chronic total occlusion (CTO) crossing catheters are the only catheters available worldwide that incorporate the additional benefits of real-time intravascular imaging during PAD treatment.

While the FDA has already cleared OCT diagnostic claims for Avinger’s Pantheris and Ocelot catheters, and reimbursement codes applicable to therapeutic peripheral interventions with the Company’s Lumivascular catheters already exist, the results of the SCAN study are intended to support an initiative to gain incremental reimbursement for OCT diagnostic imaging in the peripheral arteries similar to the reimbursement currently provided for the use of IVUS in this setting. The study will enroll up to 20 subjects diagnosed with peripheral artery disease at two centers in the United States, with the goal to acquire at least 115 matched images generated by OCT and IVUS imaging for analysis. More specifically, OCT and IVUS images will be captured at identical positions within vessel segments so that a comparison can be made between the two imaging modalities. Dr. Edward Pavillard, a vascular surgeon at PA Vascular Institute, and Dr. Luke Sewall, an interventional radiologist and president of Vascular and Interventional Professionals, will serve as physician investigators in this study. Dr. Suhail Dohad, an interventional cardiologist in Los Angeles, will also serve as an advisor to the study.

Dr. Edward Pavillard, who enrolled the first cases in the SCAN study, noted, “As a regular user of diagnostic IVUS to plan treatment and assess results after the delivery of therapy, I have found that having an intravascular view of arterial structures and disease distribution leads to better results for my patients versus if I relied solely on fluoroscopy. Given the correlation between the use of intravascular imaging and clinical outcomes, I am excited to participate in a study that will help expand the incorporation of OCT into the treatment paradigm for peripheral interventions.”

Dr. Luke Sewall commented, “OCT and IVUS have been well accepted imaging modalities for the diagnosis and treatment of atherosclerotic disease. Published data have shown that intravascular imaging may allow a clinician to more accurately assess vessel size, plaque characteristics, anatomical features, and the adequacy of interventional results. OCT and IVUS imaging also have the potential to limit the amount of radiation to which physicians and cath lab staff are exposed, and also reduce the volume of contrast agent used in the intervention, which can be particularly important in successfully treating patients suffering from impaired kidney function.”

“This trial represents an important component of our growth strategy. If successful, the results from this study should help support our application for incremental diagnostic reimbursement in procedures incorporating our Lumivascular technology,” said Jeff Soinski, Avinger’s president and CEO. “With diagnostic reimbursement already in place for IVUS imaging in the peripheral arteries, we believe that the reimbursement structure should also support the use of OCT for these types of interventions, especially given the high quality of intravascular imaging provided by OCT.”
