Clinical Validation Study for RosettaGX Reveal Published in the Journal of Clinical Pathology

Second peer-reviewed publication represents a major milestone that is expected to support continued RosettaGX Reveal momentum

PHILADELPHIA & REHOVOT, Israel--()--Rosetta Genomics Ltd. (NASDAQ:ROSG), a leading developer and provider of microRNA-based and other molecular diagnostics, announces that a clinical validation study in support of RosettaGX Reveal™ (Reveal), the Company’s first-of-its-kind microRNA classifier for indeterminate thyroid nodules, has been published in the Journal of Clinical Pathology. The article, entitled “Multicenter Validation of a MicroRNA-based Assay for Diagnosing Indeterminate Thyroid Nodules Utilizing Fine Needle Aspirate Smears,” is available online here.

Thyroid nodules are very common and most are benign, with only a 5% risk of being malignant. In order to make a diagnosis, a thyroid fine needle aspiration (FNA) biopsy is performed. In most cases, the cytopathologist is able to determine if the nodule is benign or malignant. Unfortunately, approximately 10-40% of the Fine Needle Aspirates (FNA) are categorized as indeterminate.1 This leads to many unnecessary surgeries. The RosettaGX Reveal miRNA Classifier can help to significantly reduce the number of unnecessary surgeries. The publication of data for the Reveal assay in the Journal of Clinical Pathology supports its use as a tool in the diagnosis of indeterminate thyroid nodules and highlights its ability to analyze the same thyroid cells on which the indeterminate diagnosis was based. With a market-leading 99% negative predictive value, this unique assay will help reduce the number of unnecessary surgeries.

“In addition to this clinical validation study, data from an analytical validation study published in the May 2016 edition of Cancer Cytopathology and highlighted on the cover of the journal this month, demonstrate the robustness of our Reveal assay under various laboratory conditions. Together, these two publications support our efforts to grow demand for Reveal as well as to secure additional reimbursement. In addition, this publication well positions us competitively as one of two companies to have a peer-reviewed publication of a blinded, clinical validation study for their currently marketed molecular classifier,” stated Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics.

“Following the publication in Cancer Cytopathology, we saw a significant increase in demand for Reveal that has continued to result in strong gross billings. Commercial demand for Reveal increased more than 50% from July to August, and more than 60% from August to September. We believe that publication of this data demonstrating Reveal’s ability to classify indeterminate thyroid nodules with its market leading 99% negative predictive value will support and enhance our stated goal to process more than 200 Reveal samples per month by the end of this year,” added Mr. Berlin.
