Rosetta Genomics Restructures to Reduce Operating Expenses and Focus on Commercial Opportunities

REHOVOT, Israel and PHILADELPHIA, Oct. 11, 2011 /PRNewswire/ -- Rosetta Genomics, Ltd. (NASDAQ: ROSG), a leading developer and provider of microRNA-based molecular diagnostics, today announced a corporate restructuring that is expected to result in a 50% reduction in the Company's monthly cash burn, thereby reducing annual operating expenses by approximately $4.2 million.  Under the restructuring, Rosetta Genomics has already provided notices eliminating 24 positions, and will eliminate 11 positions as soon as it can provide termination notices under Israeli employment regulations, primarily in research and development and general and administrative functions in Israel.  These measures will go into effect in early November 2011 and are being implemented to provide the Company with sufficient cash and equivalents to enable the Company to raise additional capital to fund operations.

"With the recent launch of our U.S. oncology sales force, our emphasis has shifted from research and development to product commercialization.  The elimination of these positions will allow us to concentrate our resources on growing sales of our miRview® mets2 and miRview® lung and other microRNA diagnostics in the U.S.  In tandem, we expect our partnership with PACE Claims Services, the market leader in asbestos claims administration, to begin gaining sales momentum with our miRview® meso diagnostic test that differentiates mesothelioma from carcinomas in the lung or pleura," stated Kenneth A. Berlin, President and CEO of Rosetta Genomics. "We have begun to see a significant increase in demand for our tests since the launch of our dedicated oncology sales team.  As expected, there is the usual lag between generating demand and getting paid for these tests by the applicable payors for these tests. We recently submitted our first claims to payors. Furthermore, we expect that our sales and marketing efforts will continue to show additional commercial progress in the coming quarters and, subject to obtaining adequate additional financing, we hope to be able to build on these efforts with expanding product introductions and additional sales representatives. Moving forward, our restructured research and development efforts will focus on advancing our blood-based microRNA diagnostics, specifically in heart failure, as well as on certain projects for potential partnerships that would provide the Company with additional cash infusions.

"On behalf of the Board and management, I would like to thank our employees for their dedication, passion and commitment to advancing Rosetta's microRNA technology for the benefit of patients worldwide.  While the decision to reduce headcount is a difficult one to make, we believe this restructuring is appropriate and necessary," concluded Mr. Berlin.

About miRview® Products

miRview® are a series of microRNA-based diagnostic products offered by Rosetta Genomics.  miRview® mets and miRview® mets2 accurately identify the primary tumor site in metastatic cancer and CUP.  miRview® squamous accurately identifies the squamous subtype of non-small cell lung cancer, which carries an increased risk of severe or fatal internal bleeding and poor response to treatment for certain therapies.  miRview® meso diagnoses mesothelioma, a cancer connected to asbestos exposure.  miRview® lung accurately identifies the four main subtypes of lung cancer using small amounts of tumor cells.  miRview® tests are designed to provide objective diagnostic data; it is the treating physician's responsibility to diagnose and administer the appropriate treatment.  In the U.S. alone, Rosetta Genomics estimates that approximately 200,000 patients a year may benefit from the miRview® mets and miRview® mets2 test, 60,000 from miRview® squamous, 60,000 from miRview® meso and more than 1 million patients worldwide from miRview lung.  The Company's tests are offered directly by Rosetta Genomics in the U.S., and through distributors around the globe.

About microRNAs

microRNAs (miRNAs) are recently discovered, small RNAs that act as master regulators of protein synthesis, and have been shown to be highly effective biomarkers.  The unique advantage of microRNAs as biomarkers lies in their high tissue specificity, and their exceptional stability in the most routine preservation methods for biopsies, including Formalin Fixed Paraffin Embedded (FFPE) block tissue and fine needle aspirate (FNA) cell blocks. It has been suggested that their small size (19 to 21 nucleotides) enables them to remain intact in FFPE blocks, as opposed to messenger RNA (mRNA), which tends to degrade rapidly. In addition, early preclinical data has shown that by controlling the levels of specific microRNAs, cancer cell growth may be reduced.  To learn more about microRNAs, please visit www.rosettagenomics.com .
