Rosetta Genomics to Increase the Number of U.S. Sales Territories

PHILADELPHIA and REHOVOT, Israel, June 4, 2013

"Our Rosetta Cancer Origin Test™ (formerly miRview^® mets²) has been trending positively for the past three months in terms of samples processed and samples billed. We continue to make progress in executing agreements with Preferred Provider Organizations (PPOs), such as our recently announced credentialing agreement with Prime Health, which now allow for this test to be adjudicated as 'in network' for more than 6.5 million patients in the U.S.  Our strong presence at ASCO 2013 significantly enhanced the knowledge of and interest in our microRNA-based cancer testing services.  Consequently, we believe the time is right for a strategic expansion of our sales force in order to achieve greater reach to physicians, and ultimately to ensure that our Cancer Origin Test^™ is available to more patients," said Kenneth A. Berlin, Rosetta Genomics' President and Chief Executive Officer.

Rosetta Genomics unveiled its new corporate and product branding at ASCO 2013 through various mediums including an interactive tradeshow booth that featured a high-definition promotional video and various other promotional materials. The new branding includes an updated corporate logo with the tagline, "expanding personalized medicine," and new names and logos for Rosetta's Cancer Testing Services (formally the miRview^® family of testing services), all of which were extremely well received by healthcare professionals who visited the booth.

In addition, Rosetta's Cancer Testing Services were highlighted in an "Industry Expert Theater Presentation" (IETP), during which Mr. Berlin and E. Robert Wassman, MD, FAAP, FACMG, Rosetta Genomics' Chief Medical Officer, delivered a presentation entitled, "Application of microRNAs in Oncology Diagnostics." Dr. Wassman delivered a presentation on the Cancer Origin Test^™.  During his presentation, Dr. Wassman discussed real-world case studies of patients with Cancer of Unknown or Uncertain Primary (CUP) impacted by the test results, and reviewed data from extensive validation studies that demonstrated a high level of concordance with the predictions made by leading CUP centers. 

"We are delighted with the positive reception to our IETP, and with the caliber of questions asked. We believe that through educational programs like this and our other physician outreach efforts, physicians are beginning to acknowledge the clinical value of microRNA profiling in CUP patients, and recognize that it is not a matter of whether to use such diagnostics but when to use them.  In many cases a diagnosis of Cancer of Unknown Primary is no longer acceptable now that we have more precise diagnostic assays to identify the tumor of origin and, therefore, are able to make better clinical treatment decisions," said Dr. Wassman.

Mr. Berlin added, "We received very favorable feedback on our new corporate and product branding.  We believe our modern new look and fresh promotional materials, as well as our highly successful IETP, made a significant contribution to the steady flow of visitors to our booth, and the subsequent sales leads recorded. The positive responses confirmed that our new corporate branding conveys who we are and what we do extremely well. In addition, visitors to our booth gave highly positive feedback relating to the new names and logos for our Cancer Testing Services, citing that they like the clear connection between our corporate brand and what the tests actually do."

About Rosetta Cancer Testing Services (formerly the miRview^® product line)  
Rosetta Cancer Tests are a series of microRNA-based diagnostic testing services offered by Rosetta Genomics. The Rosetta Cancer Origin Test^™ can accurately identify the primary tumor type in primary and metastatic cancer including cancer of unknown or uncertain primary (CUP). Rosetta Mesothelioma Test^™ diagnoses mesothelioma, a cancer connected to asbestos exposure.  The Rosetta Lung Cancer Test^™ accurately identifies the four main subtypes of lung cancer using small amounts of tumor cells. The Rosetta Kidney Cancer Test^™ accurately classifies the four most common kidney tumors: clear cell renal cell carcinoma (RCC), papillary RCC, chromophobe RCC and oncocytoma.  Rosetta's assays 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 200,000 patients a year may benefit from the Rosetta Cancer Origin Test^™, 60,000 from the Rosetta Mesothelioma Test^™, 65,000 from the Rosetta Kidney Cancer Test^™ and 226,000 patients from the Rosetta Lung Cancer Test^™. The Company's assays are offered directly by Rosetta Genomics in the U.S., and through distributors around the world. For more information, please visit www.rosettagenomics.com.
