–  Prospective clinical study presented at the San Antonio Breast Cancer Symposium suggests Imagio findings may help clinicians tailor patient treatment regimens –

–  Functional Imaging provides important information about the growth and location of blood vessels around breast masses as compared to anatomical imaging-

SAN ANTONIO, December 8, 2017 – Seno Medical Instruments, Inc. (Seno Medical), the leader in new technology for breast cancer diagnosis using opto-acoustic (OA/US) imaging to differentiate benign from malignant masses, reported clinical data from their clinical study demonstrating that its Imagio^™ breast imaging system achieved significant differentiation among prognostic subtypes of breast cancer (PSBC). These prognostic subtypes provide important information about the genes that each patient’s cancer expresses. The data are being presented today at 5:00 p.m. during a poster presentation [#P5-02-04] at the San Antonio Breast Cancer Symposium taking place December 5 – 9.

“Confirming a diagnosis of breast cancer is just the first step in understanding the pathology of a patient’s tumor,” said study presenter Stephen Grobmyer, M.D., Director, Breast Surgical Oncology, Cleveland Clinic. “Determining a patient’s prognostic subtype of breast cancer is essential for understanding how tumors will respond to specific therapies and selecting a treatment regimen that offers the patient the best chance of a positive outcome. The findings that OA/US may differentiate among several breast cancer subtypes suggest that this novel imaging methodology could potentially provide a non-invasive alternative to biopsy without sacrificing information about the molecular pathology of the tumor. This could be an important advance for women with breast cancer.”

The prospective, multi-center study was conducted at 16 centers in the United States. A total of 1,808 breast masses in 1,739 subjects assessed as BI-RADS (Breast Imaging and Reporting Data System, or BR) category 3, 4 or 5 were imaged with OA/US, resulting in the identification of 678 malignant lesions. Eight blinded readers scored these 678 lesions based on three internal features of the tumor and two external features of the tumor boundary and surrounding tissue. An experienced central breast pathologist who was blinded to the OA/US assessment confirmed the pathologic diagnoses. Biopsy specimens were obtained and assessed for the expression of four genes that comprise the PSBC: estrogen receptor (ER), progesterone receptor (PR), HER2-neu (HER2) and Ki-67. The PSBCs are defined as follows:

• Luminal A (LUM-A): ER/PR (+) and Ki-67 and HER2 (-). These tumors are often low grade, with slow tumor growth and are associated with the most positive prognosis.
• Luminal B (LUM-B): ER (+), PR (+/-), Ki-67 (+) and HER2 (+/-). These tumors are also low grade but grow more quickly than LUM-A.
• Triple-negative breast cancer (TNBC): ER/PR (-), Ki-67 (+/-) and HER2 (-). These tumors are aggressive and typically associated with poor prognosis.
• HER2-enriched (HER2): ER/PR (-), Ki-67 (+/-) and HER2 (+). These tumors tend to grow quickly but are responsive to anti-HER2 targeted therapies.

Tumors not meeting the definition of any of these categories were deemed unclassified.

Key findings from the study include:

• There was a significant difference in the sum of the three internal OA/US features between LUM-A and TNBC subtypes (p = 0.0256) and borderline significance between LUM-A and LUM-B (p = 0.0831) and LUM-A and HER2 (p = 0.0707).
• There was a significant difference in the sum of the two external OA/US features between LUM-A and TNBC subtypes (p = 0.0001) and LUM-B and TNBC subtypes (p = 0.0020) and borderline significance between LUM-A and HER2 (p = 0.0617).
• TNBC tumors showed mainly internal findings consisting of polymorphic intensely deoxygenated vessels.
• LUM-A tumors showed a paucity of internal findings and abundant external findings consisting of short perpendicularly oriented tumor vessels in the boundary zone (BZ whiskers), partial BZ deoxygenated blush, and peripheral radiating deoxygenated vessels.

“The results of this study underscore the clinical benefits that can be achieved with Imagio’s functional imaging technology,” said Tom Umbel, CEO of Seno Medical Instruments. “Unlike anatomical imaging techniques, such as mammography or conventional ultrasound, functional imaging provides important information about the growth and location of blood vessels in and around breast masses. These findings show that not only does this functional imaging data allow for more accurate diagnosis of breast cancer, it also correlates with existing prognostic breast cancer subtypes. This data may suggest that OA/US has the potential to provide physicians with a powerful tool for gaining insight into the molecular pathology of each patient’s tumor without the need for invasive biopsy procedures. Seno Medical is committed to improving the care and outcomes of women with breast cancer through improved non-invasive diagnostic approaches.”

The Imagio™ OA/US breast imaging system was designed and is being studied to identify two functional hallmarks of cancer: the presence of abnormal blood vessels (tumor angiogenesis) and the relative reduction in oxygen content of blood that occurs in cancer compared to benign masses and normal tissues.   The technology is the subject of a U.S. PMA filing with the FDA and does have European CE Mark.

CHICAGO, November 28, 2017 – Seno Medical Instruments, Inc. (Seno Medical), the leader in new technology for breast cancer diagnosis using optoacoustic (OA/US) imaging to differentiate benign from malignant masses, today announced clinical data demonstrating that its Imagio^™ breast imaging system effectively downgraded the risk classification of benign breast masses and upgraded the risk classification of malignant masses compared with ultrasound (US) alone. The data are being presented today at 3:20 p.m. CDT during an oral presentation by a principal study investigator at the Radiology Society of North America 103^rd Annual Meeting, taking place November 26 – December 1 in Chicago.

The prospective, controlled, multi-center study was conducted at five centers in the Netherlands between March 2015 and February 2016 and enrolled 217 patients at least 18 years of age with at least one breast mass totaling 223 breast masses classified as BI-RADS (Breast Imaging and Reporting Data System) category 4A or 4B and with a corresponding probability of malignancy (POM) ranging from >2% to 50% based on prior US assessment. The likelihood that a breast mass is malignant increases with increasing BI-RADS category number. All subjects underwent an OA/US evaluation after conventional US and prior to biopsy. The OA/US data were used to estimate the POM on a scale from 0% to 100% and, when appropriate, the BI-RADS classification determined by conventional US was adjusted. Biopsies were performed within 30 days of enrollment and after the OA/US procedure had been performed and interpreted. The OA/US results were compared with biopsy results as the reference standard. Patients were asked to complete a satisfaction survey after undergoing OA/US evaluation

“The negative consequences of biopsies of benign breast masses include pain, anxiety, fear, direct expenses and indirect expenses related to work missed and managing complications,” said study investigator Gisela L.G. Menezes, M.D., Ph.D. and postdoc at the University Medical Center Utrecht, the Netherlands. “Using OA/US, benign masses originally classified as suspicious may be downgraded to probably benign or benign, potentially decreasing the number of biopsies of benign lesions.”

Key findings from the study include:

• In the intent to diagnose (ITD) population of 209 patients with 215 masses, 68% were benign, 31.1% were malignant and 0.9% were considered high-risk lesions based on histopathology of biopsy specimens.
• Based on US of 146 benign lesions, 81.5% and 18.5% were classified as BI-RADS 4A and 4B, respectively. Sixty benign masses were correctly downgraded from BI-RADS 4A or 4B to BI-RADS 3 or 2 with OA/US (p<0.0001).
  • Of benign masses classified as BI-RADS 4A, 47.9% were downgraded to BI-RADS 3 or 2 and 12.3% were upgraded to 4B.
  • Of 27 benign masses classified as 4B, 11.1% were downgraded to BI-RADS 3, 6.1% were upgraded to 4C and 0.6% were upgraded to 5.
• Overall, 41.1% of benign breast masses originally classified as BI-RADS 4A or 4B on US could be downgraded to probably benign or benign masses (BI-RADS 3 or 2) with OA/US, and 49.2% of malignant breast masses could be upgraded to a higher BI-RADS category.
• The OA/US true positive rate was 95.5%.
• There were no safety issues related to OA/US.
• The patient satisfaction survey showed that approximately 95% of the patients agreed that OA/US had an acceptable level of comfort and 84% agreed that OA/US scan time was acceptable.

“The results from this study indicate that a substantial percentage of breast masses classified as BI-RADS 4A or greater, based on conventional US, can be downgraded with OA/US. This suggests that the functional and morphologic information gained with OA/US has the potential to benefit women undergoing breast mass evaluation,” said Tom Umbel, CEO of Seno Medical Instruments. “Detection of a breast mass can make a woman very anxious, and it is incumbent on everyone involved in assessing breast masses to minimize patients’ stress and anxiety while providing the most accurate diagnosis possible. We believe that the Imagio system has an important role to play in improving breast cancer diagnosis and ensuring optimal patient care and outcomes.”

The Imagio™ breast imaging system was designed and is being studied to identify two functional hallmarks of cancer: the presence of abnormal blood vessels (tumor angiogenesis) and the relative reduction in oxygen content of blood that occurs in cancer compared to benign masses and normal tissues.   The technology has its CE mark in Europe and is the subject of a U.S. PMA filing with the FDA.

Results Presented in a High Impact Clinical Trial Session at the Radiology Society of North America (RSNA) Annual Meeting

CHICAGO, November 27, 2017 – Seno Medical Instruments, Inc. (Seno Medical), the leader in new technology for breast cancer diagnosis using opto-acoustic ultrasound (OA/US) imaging to differentiate benign from malignant masses, today announced positive data from PIONEER, a Phase III pivotal trial of its Imagio^™ breast imaging system. The study found that OA/US was more specific than device gray-scale ultrasound alone (US) in differentiating malignant from benign breast lesions and was non-inferior to US with respect to sensitivity. This means that OA/US detected a similar number of malignant lesions as US but had a lower rate of false positive malignant diagnoses. These data were highlighted during an oral presentation by a principal investigator involved with the study at the Radiology Society of North America 103^rd Annual Meeting, taking place November 26 – December 1 in Chicago.

PIONEER was a U.S., prospective, multi-institutional study that enrolled 2,105 women over the age of 18 years. All participants had a breast mass assessed by initial conventional site ultrasound as BI-RADS (Breast Imaging and Reporting Data System, or BR) category 3, 4, or 5. The likelihood that a breast mass is malignant increases with increasing BR category number. Radiologists at each clinical site also assigned each mass a probability of malignancy (POM) ranging from 3% to 99% based on mammographic and US features. Patients with masses categorized as > BR4A had OA/US prior to undergoing core needle biopsy within 45 days of their initial visit and subsequent biopsy or excision surgery within 45 of the initial biopsy. Patients with BR3 masses had OA/US upon enrollment and underwent biopsy or conventional site US and OA/US 12 months after enrollment. Patients who underwent biopsy due to new clinical or imaging findings within the 12-month period had additional OA/US imaging within 45 days prior to the biopsy. Independent breast imagers who were blinded to the biopsy and other clinical information read the OA/US and device US images; an independent central pathologist who was blinded to the imaging data reviewed all of the biopsy reports.

Key findings from the study include:

• Seven independent readers blinded to clinical and biopsy information conducted 12,283 mass reads.
• In the intent to diagnose (ITD) population 1808 masses were evaluated in 1,739 subjects (678 malignant, 889 benign, 190 benign with 12-month follow-up).
• In the ITD population of 1,739 subjects and 1,808 masses, diagnostic specificity for benign masses was 43% for OA/US and 28.1% for US, corresponding to a 14.9% absolute specificity advantage for OA/US over US (p<0.0001).
• Subgroup analyses showed no significant differences in specificity for either OA/US or US based on breast density, mass size, palpability, distance from nipple and depth.
• Specificity of OA/US was 8.4% higher in patients <50 years of age than in patients aged 60 to <70 years; there was no difference in sensitivity by age group.
• For masses that were benign, OA/US resulted in downgrading 34.5% of US reads (from BR4A to <BR3 or BR3 to BR2). OA/US also resulted in upgrading 6.0% of US mass reads, for a net downgrade rate of 28.5% (p<0.0001).
• For masses that were malignant, OA/US resulted in upgrading 47.0% of mass reads classified as BR3 by US and downgrading to BR2 27.3% of mass reads classified as BR3 by US.
• Positive predictive value for masses assessed as BR4A or higher was 51.5% for OA/US compared with 46.3% for US; negative predictive value for masses assessed as BR3 or lower is 94.4% for OA/US compared with 97.0% for US.
• Ten patients reported 11 adverse events potentially related to the OA/US procedure, all of which were considered mild and resolved within a few days (7 paresthesias, 1 erythema, 1 warmth, 1 tenderness and 1 case of possible dermatitis of indeterminate origin).

“These data demonstrate that OA/US improved diagnostic specificity compared with US, resulting in reclassification of both benign and malignant lesions,” said Erin Neuschler, M.D., Assistant Professor of Radiology at the Northwestern University Feinberg School of Medicine and the co-principal investigator of the PIONEER study. “The ability to downgrade the BI-RADS assessment of some benign masses may lead to fewer false positive examinations, short-term interval follow-up studies, and benign biopsies, potentially improving the accuracy of the diagnostic work-up and reducing some of the limitations and perceived harms of breast imaging.” 

“This pivotal trial supports the Imagio system as an important advancement in evaluating breast masses and more accurately differentiating malignant and benign lesions,” said Tom Umbel, CEO of Seno Medical Instruments. “OA/US offers patients and clinicians an alternative diagnostic method that may increase specificity without significantly impacting sensitivity. False positive examinations and negative biopsies increase women’s anxiety, pain and radiation exposure, and are a contributing factor in non-compliance with current breast cancer screening recommendations. The Imagio OA/US system shows the potential to positively affect these concerns and reduce healthcare costs in the process.”

The Imagio™ breast imaging system was designed and is being studied to identify two functional hallmarks of cancer: the presence of abnormal blood vessels (tumor angiogenesis) and the relative reduction in oxygen content of blood that occurs in cancer compared to benign masses and normal tissues.   The technology is CE marked in Europe and the subject of a U.S. PMA filing with the FDA.

Results Presented at the American Roentgen Ray Society (ARRS) Annual Meeting

San Antonio, May 10, 2017 – Seno Medical Instruments, Inc. (Seno Medical), the leader in new technology for breast cancer diagnosis, is using opto-acoustic (OA/US) imaging to differentiate benign from malignant masses. Seno Medical announced that its Imagio^™ breast imaging system results correlate with the histopathological findings of benign and malignant breast masses. These data were highlighted during an oral presentation at the American Roentgen Ray Society (ARRS) Annual Meeting, which took place from May 1-5 in New Orleans.

The basis for this presentation is the institutional review board (IRB)-approved Phase III pilot study, which was designed to determine the histopathologic basis of OA/US breast imaging and investigate its ability to differentiate benign and malignant masses. A total of 92 patients with 94 solid or complex cystic and solid breast masses assessed as BI-RADS 3, 4 or 5 on conventional diagnostic ultrasound (CDU) were imaged with OA/US. For each mass, five pre-determined OA features – three internal features and two external features – were evaluated. The three internal features (internal vessels, blush and hemoglobin) and two external features (boundary zone vessels and peripheral zone vessels) were scored and correlated with benign and malignant histopathology.

Mean OA scores were higher for malignant masses compared to benign masses for all individual internal and external features, as well as for combined internal and external OA features. Statistical analysis showed that these differences were highly statistically significant. External features were more predictive of malignancy than internal features, with greater differences in their means and 99% confidence intervals between benign and malignant masses.

“These data reinforce previous findings suggesting that opto-acoustic diagnostic imaging may improve our ability to differentiate between benign and malignant breast masses. This could help us decrease the number of unnecessary breast biopsies performed for benign findings, reducing patient anxiety, discomfort and health care cost,” said Reni Butler, MD, principal study investigator and Assistant Professor of Radiology and Biomedical Imaging at Yale University School of Medicine. “Unlike previously investigated functional modalities, opto-acoustic imaging provides real-time anatomic and functional information without ionizing radiation or the need for IV contrast injection, making it a potentially safer and more convenient option for patients.”

“We are encouraged by these promising study results, further underscoring the clinical utility of the Imagio OA/US breast imaging system as an effective tool to aid in the assessment of breast masses,” said Tom Umbel, CEO of Seno Medical Instruments. “We are confident that OA/US imaging has the potential to address significant unmet needs in the characterization and diagnosis of breast lesions and look forward to announcing the results of PIONEER, our pivotal U.S. study of more than 2,000 patients, later this year.”

The Imagio™ OA/US breast imaging system was designed and is being studied to identify two functional hallmarks of cancer: the presence of abnormal blood vessels (tumor angiogenesis) and the relative reduction in oxygen content of blood that occurs in cancer compared to benign masses and normal tissues.   The technology is the subject of a U.S. PMA filing with the FDA.
