Clinical Utility Survey Demonstrates the Potential of RosettaGX Reveal(TM) to Significantly Reduce Unnecessary Thyroid Surgeries

-Demonstrates 95% Negative Predictive Value (NPV) in a Population with High Malignancy Rate; Confirms High NPV Shown in Earlier Reveal Validation Study

-Results Highlighted in Oral Presentation at the 3rd World Congress on Thyroid Cancer

PHILADELPHIA, PA and REHOVOT, ISRAEL / ACCESSWIRE / July 31, 2017 / Rosetta Genomics Ltd. (ROSG), a genomic diagnostics company that improves treatment decisions by providing timely and accurate diagnostic information to physicians, announces that data highlighting the integration of the RosettaGX Reveal™ (Reveal) into clinical practice was presented in an Oral Presentation at the 3rd World Congress on Thyroid Cancer on July 30, 2017. The Reveal microRNA classifier is a first-of-its-kind assay offering testing from a routinely prepared cytology slide that analyzes the exact cells used to make the original indeterminate diagnosis.

The oral presentation titled, "Incorporating the RosettaGX Reveal™ assay into clinical practice can significantly reduce the number of unnecessary surgeries associated with Indeterminate Thyroid Nodules (ITNs,)" was delivered by Nicole Massoll, M.D., Lab and Medical Director of Rosetta Genomics.

The presentation reviewed data on more than 1800 of the first patients tested with Reveal and demonstrated a high benign classification rate, which is important because the vast majority of ITNs are benign. Reveal was developed to identify these benign cases and help avoid unnecessary surgeries.

In addition, the presentation covered the results of a new survey of the use of Reveal in the clinical setting. The survey included responses from 40 physicians from 34 medical centers who utilize the Reveal assay in their clinical practices and reviewed their experience from 371 patients as it related to impact on patient management, decision to send patients to surgery or the extent of surgery, ease-of-use and overall feedback.

The survey results suggested that Reveal prevents unnecessary surgeries. In the pre-molecular era, the rate of surgery for ITNs was 74% [1] and the rate of surgery in this survey was 30.5%. In addition, 91% of the physicians who participated in the survey stated that Reveal changed the way they managed their patients with ITNs; 73% predicted that Reveal will decrease the number of patients sent to surgery; and 85% of patients with Reveal Benign results were able to avoid surgery.

Importantly, Reveal's performance in those cases from the survey in which there was surgical outcome demonstrated a negative predictive value (NPV) of 95% in a setting with a relatively high prevalence of malignancy (35%). In addition, respondents gave a high rating on the assay's ease-of-use, particularly as Reveal is performed from a routinely prepared cytology smear or ThinPrep slide. Unlike other molecular tests, Reveal analyzes the exact cells used to make the indeterminate cytology diagnosis, without the need for additional passes, repeat FNA procedures, refrigeration or special shipping.

"We are delighted to have presented these compelling data suggesting that Reveal can prevent unnecessary surgeries for patients with an ITN before an audience of expert physicians that are dedicated to improving the diagnosis and treatment of thyroid cancer," stated Dr. Massoll. "These survey responses provide real world clinical experience in support of incorporating Reveal into clinical practice where it has shown to be a useful tool for further classification of ITNs with high sensitivity and high NPV even in settings where there is a high prevalence of thyroid cancer. Reveal's high NPV can give physicians the confidence to rely on a benign test result, thus allowing them to observe their patients in lieu of taking them to surgery. These results are similar to the results from Reveal's clinical validation study, further confirming the assay's high NPV."

"The positive results from this survey of physicians utilizing Reveal in real-world clinical practice are very encouraging and further support our strategy to increase our focus and investment in expanding the commercial, promotional and reimbursement efforts for Reveal to accelerate this differentiated product's growth. Data such as these provide a solid building block for our team in developing a compelling value proposition for the integration of Reveal in clinical practice as well as for gaining increased coverage by payers," said Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. "Reveal's high NPV and ability to analyze the exact cells that were used to make the original ITN diagnosis are significant competitive advantages over other molecular ITN assays, which we expect will drive Reveal's adoption in ITN classification. We continue to believe that Reveal offers a significant opportunity for both short- and long-term revenue growth and these positive data support that thesis."
