Rosetta Genomics Expands Management Team, Laboratory Capacities and Commercial Operations

Prepares for Anticipated Growth for Award-Winning, Next-Generation microRNA Diagnostics

Rosetta Genomics Ltd. (ROSG), a leading developer and provider of microRNA-based molecular diagnostics, today announced the completion of three executive hires and an expansion of its commercial  operations in preparation for expected sales growth of its microRNA diagnostic assays, specifically its flagship product miRview® mets2.  The Company recently announced a co-marketing agreement with Precision Therapeutics, Inc. for miRview® mets2, as well as a recent decision by Medicare to reimburse the miRview® mets2 assay.

"In addition to the terrific management hires we are announcing today, we have begun the process of adding sales representatives to our oncology-focused sales team and have already doubled the capacity of our laboratory operations in anticipation of an increase in demand as our miRview® mets2 assay gains further market acceptance," stated Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics.  "In addition, we have begun the process of adding to our national accounts management team to work with private payers to increase the number of covered lives for our miRview® mets2 assay.

"With 200,000 patients in the U.S. diagnosed with Cancers of Unknown or Uncertain Primary ("CUP") each year, there is a significant market opportunity for miRview® mets2.  Our goal is to articulate our value with this lead product and then leverage that success to advance the commercialization of other products in our portfolio," added Mr. Berlin.
