Rosetta Genomics Ltd. and Precision Therapeutics, Inc. Enter into Co-Marketing Agreement for miRview&#0174 mets(2) Assay

PHILADELPHIA and REHOVOT, Israel, July 24, 2012 /PRNewswire/ -- Rosetta Genomics Ltd. (NASDAQ: ROSG), a leading developer and provider of microRNA-based molecular diagnostic assays, announced today that it has entered into a co-marketing agreement for its miRview^® mets² assay for the accurate identification of the tumor of origin in Cancers of Unknown or Uncertain Primary ("CUP") with Precision Therapeutics Inc., a life science company known for its expertise in the science of personalizing cancer therapy by advancing genomic testing and bioinformatics.

Under the terms of the agreement, Rosetta Genomics granted Precision Therapeutics the co-exclusive right, along with Rosetta Genomics, to co-market the miRview^® mets² assay in the U.S. through July 30, 2014, with certain pre-specified performance milestones. Rosetta Genomics will continue to record all revenues for miRview^® mets² and will remain responsible for sample collection, processing and billing. Precision Therapeutics, with one of the largest sales forces in oncology diagnostics and considerable experience in the personalized medicine sector, is expected to launch its miRview^® mets² co-marketing effort in August 2012.

"Precision Therapeutics is a strong partner to help maximize the potential of miRview^® mets² in a critically important market, where accurate identification of the primary cancer directly impacts treatment decisions. With approximately 200,000 CUP patients in the U.S., we believe this co-marketing agreement will significantly enhance our reach and access to the physicians who diagnose cancer and who treat these patients, including pathologists and oncologists," said Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. "This co-marketing agreement, as well as the recent Medicare decision to reimburse the miRview^® mets² assay, significantly strengthens our prospects for widespread market adoption and revenue growth."

"We are especially pleased to partner with Rosetta Genomics to enhance the commercial distribution of the miRview^® mets² assay, as it is a best-in-class CUP assay that utilizes cutting-edge microRNA expression as a platform, which we believe provides greater accuracy in identifying these difficult to diagnose tumors of unknown or uncertain origin. The data reported from external validation studies show a high level of concordance between the miRview^® mets² assay and expert diagnoses in true CUP patients demonstrating the clinical benefit of looking at microRNA," stated Sean McDonald, President and Chief Executive Officer of Precision Therapeutics.

"This collaboration with Rosetta Genomics underscores our commitment to offering high quality and high utility solutions to physicians along the entire continuum of care with the goal to improve outcomes for patients. Together with Rosetta Genomics' dedicated oncology team, we will reach out to an even larger group of healthcare providers in order to benefit patients who are diagnosed with CUP," added Mr. McDonald.

About Cancer of Unknown Primary Origin

According to the American Cancer Society, an estimated 2 to 5 percent of all cancer patients have metastatic (secondary) tumors for which routine testing cannot locate the primary site. This is called cancer of unknown primary origin (CUP). Patients may be diagnosed with cancer of unknown primary origin if the primary tumor is too small to be identified with routine imaging tests, it regresses (disappears) before a secondary tumor arises, or the secondary tumor has several possible primary sites.

Cancer of unknown primary origin can appear anywhere in the body, but is most commonly found in the lymph nodes, liver, lungs, bones, or skin.

About miRview^® Products

miRview^® are a series of microRNA-based diagnostic products offered by Rosetta Genomics. miRview^® mets² accurately identifies the primary tumor type in primary and metastatic cancer including Cancer of Unknown Primary (CUP). 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^® kidney accurately classifies the four most common kidney tumors: Clear Cell Renal Cell Carcinoma (RCC), Papillary RCC, Chromophobe RCC and Oncocytoma. 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 200,000 patients a year may benefit from the miRview^® mets² test, 60,000 from miRview^® meso, 54,000 from miRview^® kidney and 226,000 patients from miRview^® lung. 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.mirviewdx.com.
