Seno Medical Launches CONFIDENCE Registry Study for Imagio® Breast Imaging System

Prospective, controlled multi-center observational registry will include ~12 sites and 600 patients to collect data on opto-acoustic/ultrasound (OA/US) system.

[SAN ANTONIO, TX – October 21, 2021] Texas-based Seno Medical Instruments, Inc. (Seno) has launched its CONFIDENCE registry to evaluate the efficacy of imaging with opto-acoustic/ultrasound (OA/US) to diagnose breast abnormalities including cancer using its groundbreaking Imagio® Breast Imaging System.

Approximately twelve sites will participate in the international registry, with a target of over 600 total patients participating through the study’s timeframe, ending in 2024.

Several international sites in the Netherlands are currently recruiting for the study. The study’s intent is to obtain real-life, post-market data on the use of the Imagio® System and to provide evidence on the general use and performance of the system in a real-world setting.

“We believe, much like other hybrid imaging modalities such as PET/CT, the sum of opto-acoustics and ultrasound together provide greater sensitivity and specificity than either of the imaging modalities individually,” says Shaan Schaeffer, VP of Clinical Operations at Seno.

CONFIDENCE registry endpoints to be analyzed include:

Breast biopsy procedures caused by false-positive diagnostic assessments in the United States cost the healthcare system more than $2 billion per year.[i] Seno’s Imagio® technology could mitigate that with its non-invasive OA/US technology to help physicians better differentiate between benign and malignant breast lesions in real time, helping providers characterize and differentiate masses that may—or may not—require more invasive diagnostic evaluation.

Seno’s Chief Executive Officer, Tom Umbel, commented, “This registry study will help us substantiate the efficacy of the Imagio® System in a real-world setting and the ability for OA/US to benefit physicians and patients around the world.”

The company’s OA/US technology combines laser optics and grayscale ultrasound to provide fused functional and anatomical breast imaging. The opto-acoustic images provide a unique blood map in and around breast masses, while the ultrasound provides a traditional anatomical image. Through the appearance or absence of two hallmark indicators of cancer – angiogenesis and deoxygenation – Seno Medical has shown that the Imagio® OA/US Breast Imaging System will be a more effective tool to help radiologists confirm or rule out malignancy compared to traditional diagnostic imaging modalities – without exposing patients to potentially harmful ionizing radiation (x-rays) or contrast agents. In addition to the novel imaging provided by the Imagio® System, Seno includes an artificial intelligence (AI) decision-support tool (the SenoGram®) to aid physicians in interpreting the new images that, along with training and certification, helps radiologists make the transition from ultrasound alone to OA/US imaging.

The system is indicated for use by trained and qualified healthcare providers to evaluate palpable and non-palpable breast abnormalities in adult patients who are referred for diagnostic imaging breast work-up following clinical presentation or other imaging examinations such as screening mammography.

Seno Medical Instruments, Inc. is a San Antonio, Texas-based medical imaging company committed to the development and commercialization of a new modality in cancer diagnosis: opto-acoustic imaging. Approved by the US FDA in January 2021, Seno Medical’s Imagio® Breast Imaging System fuses opto-acoustic technology with ultrasound (OA/US) to generate real-time functional and anatomical images of the breast.
