SAN ANTONIO, TX \u2013 September 23, 2014 \u2013 Seno Medical Instruments, Inc.<\/strong>, the company pioneering the development of opto-acoustic technology as a new tool to improve the process of diagnosing breast cancer, announced today it has completed active enrollment of subjects in its U.S.-based PIONEER Pivotal Study of Imagio\u2122. The study was designed to determine if this technology will provide information to the physician to determine if a woman may avoid negative biopsies. This information will serve as the basis for the company\u2019s Premarket Approval Application (PMA) with the U.S. Food and Drug Administration (FDA). \u201cThere is a significant unmet medical need for more accurate diagnostic imaging technologies to help physicians confirm and rule out breast cancer before the patient has to undergo an invasive procedure. More information at the imaging stage could help us make more informed decisions regarding whether we should send the patient for a surgical or needle biopsy,\u201d said Reni Butler, MD, Assistant Professor of Diagnostic Radiology at the Yale School of Medicine in New Haven, Conn. and the co-principal investigator for the study.<\/p>\n

Imagio\u2122 was designed to identify two functional hallmarks of a potential malignancy: the presence of abnormal blood vessels (angiogenesis) and the relative reduction in oxygen content of hemoglobin. The technology is non-invasive and does not require contrast agents or radio-isotopes, which are required for other modalities such as magnetic resonance imaging (MRI) or positron emission tomography (PET), nor does it use ionizing radiation (x-ray).<\/p>\n

\u201cEarlier data from a feasibility study of Imagio\u2122 led to encouraging results and we look forward to seeing the outcomes from this pivotal study. If the results are consistent with the earlier, smaller studies, we believe this could be an important new technology to help improve the diagnosis of breast cancer and allow many women with benign lesions to have short-interval Imagio\u2122 follow-up and avoid a biopsy,\u201d said co-principal investigator Erin Neuschler, MD, Northwestern Medicine\u00ae Radiologist and Assistant Professor of Radiology at Northwestern University Feinberg School of Medicine in Chicago.<\/p>\n

The Imagio\u2122 study was conducted in 16 leading institutions throughout the U.S. with more than 2,100 subjects enrolled. The study was designed to measure the sensitivity and specificity of Imagio\u2122 compared to Imagio\u2122 grayscale ultrasound imaging in breast lesions using the probability of malignancy (POM). Subjects who enrolled in the study underwent a traditional ultrasound and an Imagio\u2122 scan. Physicians only used traditional ultrasound findings to determine if the subject should advance to the biopsy phase. The Imagio\u2122 results were later interpreted by an independent reader panel. Subjects who had a negative diagnostic ultrasound will be re-evaluated 12 months after their initial examination to confirm the negative results as a true negative.<\/p>\n

\u201cCompleting active enrollment is a significant milestone in Seno\u2019s efforts to commercialize Imagio\u2122. We developed Imagio\u2122 with the goal of reducing the number of imaging tests and invasive procedures women currently have to undergo to learn if a suspicious breast mass is cancerous or not. We would like to thank our investigators and their dedicated teams for participating in this important study. We hope Imagio\u2122 will have a significant impact on the diagnosis of breast cancer in the future,\u201d said Janet Campbell, CEO of Seno Medical Instruments.<\/p>\n

According to the American Cancer Society\u2019s estimates, 232,340 new cases of invasive breast cancer and an additional 64,640 cases of in situ breast cancer were diagnosed and approximately 39,620 women in the U.S. died from the disease during 2013. Only lung cancer accounts for more cancer deaths in women.<\/p>\n

Seno\u2019s Imagi\u2122o fuses opto-acoustics, a technology based on \u201clight-in and sound-out,\u201d with diagnostic ultrasound. The opto-acoustic images provide a unique blood map in and around suspicious breast masses. Cancerous tumors grow relatively quickly and require significant amounts of blood and oxygen, so a network of blood vessels grows around cancerous masses. Imagio\u2122 provides images of these networks and a map of relative oxygen-rich or oxygen-deprived blood. Unlike other functional fusion technologies, Imagio\u2122 uses no x-rays (ionizing radiation) or injectable contrast agents to obtain its information, thereby reducing the patient\u2019s exposure to any potentially harmful aspects of imaging.<\/p>\n

About Seno Medical Instruments, Inc.<\/strong><\/p>\n

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. Seno\u2019s Imagio\u2122 breast imaging system fuses opto-acoustic technology with ultrasound to generate functional and anatomical images of the breast. The opto-acoustic images provide a unique blood map around suspicious breast masses while the ultrasound provides a traditional anatomic image. Through the appearance or absence of the two hallmark indicators of cancer \u2013 angiogenesis and deoxygenation \u2013 Seno believes that Imagio\u2122 images will be a more effective tool to help radiologists confirm or rule out malignancy than current diagnostic imaging modalities \u2013 without exposing patients to potentially harmful ionizing radiation (x-rays) or contrast agents. Seno\u2019s platform technology may also address other disease applications in organs other than the breast, as well as assessing other breast problems, such as early response to chemotherapy or hormonal treatments of breast cancer.
