New York State Grants Final Approval for miRview® lung; Expands Access for Rosetta Genomics' microRNA Diagnostic for Identification of Four Major Subtypes of Lung Cancer

New, Targeted Therapies Make Accurate Classification of Lung Cancer Increasingly Important

 Rosetta Genomics (ROSG), a leading developer and provider of microRNA-based molecular diagnostic assays, announces that the New York State Department of Health has given the Company final approval for its miRview^® lung assay following conditional approval issued in June 2012.  With this final approval, Rosetta Genomics can continue to offer the miRview^® lung assay in all 50 U.S. states. New York is the only U.S. state that requires an independent regulatory review process for laboratory-developed tests.

miRview^® lung is the Company's proprietary microRNA-based assay that can accurately differentiate between the four main subtypes of lung cancer using small amounts of tumor cells. 

"We are pleased to have final New York State approval for our micro-RNA-based miRview lung assay.  This represents an important validation of our technology as many jurisdictions around the world recognize the rigor of review in the state of New York.  With the introduction of targeted lung cancer therapies, along with new targeted drugs entering the clinical arena, accurate classification of lung cancer is becoming increasingly important to better assess efficacy profiles and to enhance treatment strategies," noted Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. "We look forward to continuing to offer this important assay to the benefit of patients and physicians throughout the U.S. where, according to the National Cancer Institute, there are an estimated 226,000 new cases of lung cancer and an estimated 160,000 lung cancer related deaths expected in 2012."

About miRview^® lung
miRview lung accurately identifies the four main subtypes of lung cancer with a sensitivity of 95%, using very small pre-operative biopsies such as fine needle aspirate and cytological samples.  The assay differentiates neuroendocrine tumors from non-small cell lung tumors (NSCLC), and then further subtypes neuroendocrine tumors into small cell lung cancer and carcinoid; and subtypes NSCLC tumors into squamous and non-squamous.   

About miRview^® Products
miRview^® products are a series of microRNA-based molecular diagnostic products offered by Rosetta Genomics. The miRview^® mets² assay accurately identifies the primary tumor type in patients with primary or metastatic Cancer of Unknown or Uncertain primary (CUP). miRview^® meso diagnoses mesothelioma, a cancer connected to asbestos exposure.  miRview^® lung accurately identifies the four main subtypes of lung cancer. miRview^® kidney accurately classifies the four most common kidney tumors: clear cell renal cell carcinoma (RCC), papillary RCC, chromophobe RCC and oncocytoma.  miRview^® 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 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.
