Rosetta Genomics Receives Key U.S. Patent Allowance for its Novel Kidney Cancer Test

by | Mar 27, 2015 | Kidney Cancer News

PRINCETON, N.J. & REHOVOT, Israel–(BUSINESS WIRE)–Rosetta Genomics Ltd. (NASDAQ:ROSG), a leading developer and provider of microRNA-based molecular diagnostics, announces receipt of a Notice of Allowance for U.S. Patent Application No. 13/412,020, entitled, “Gene Expression Signature for Classification of Kidney Tumors.” The patent is owned jointly with Tel Hashomer Medical Research Ltd., the technology transfer company of the Chaim Sheba Medical Center in Israel.

“Gene Expression Signature for Classification of Kidney Tumors.”

The allowed patent claims a method for distinguishing four different types of kidney cancer: oncocytoma, clear cell renal cell carcinoma (RCC), papillary (chromaphil) RCC and chromophobe RCC in a human subject with renal cancer, through the expression profile of a unique set of 24 microRNAs and a classifier algorithm.
The impact of the limitation of diagnostic capability in renal oncocytoma was highlighted by a recent health economics outcome review of the management of kidney masses1. This study clearly demonstrated the adverse economic and health outcomes impact of poor pre-operative diagnosis, and confirmed the reported very low rates of pre-nephrectomy biopsy. In their analysis of the IMS LifeLink database, covering more than 60 million commercially insured patients in the U.S., the authors found that approximately 1 in 6 who underwent a nephrectomy for suspected renal cell cancer were subsequently identified as having benign disease, with an economic impact of approximately $26,500 per patient. This is in contrast to total expenditures of approximately $1,300 pre-operatively today, most commonly for one or more CT examinations. They projected that this represents more than 10,000 unnecessary surgeries annually in the U.S. alone.
“This U.S. patent allowance will provide core protection for the Rosetta Kidney Cancer Test which accurately distinguishes between the four main subtypes of kidney cancer. We believe that the different long-term prognosis for these four subtypes makes the correct pathological diagnosis of a renal cancer critically important for the clinician, especially for oncocytomas so as to avoid unnecessary surgeries, ” said Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. “In addition to reducing the number of unnecessary surgeries in the case of oncocytomas, new molecularly-targeted therapeutics for kidney cancer are making accurate sub-classification of tumor type important for optimizing treatment choices and improving outcomes.”
“With 42 issued patents, four allowed patents and 46 patents pending worldwide, our growing intellectual property position continues to provide protection for and solidify our global leadership position in microRNA biomarker technology and in creating differentiated and proprietary content in the area of personalized medicine,” concluded Mr. Berlin.
Kidney cancer is among the ten most common cancers in both men and women. Kidney cancers account for more than 3% of adult malignancies and cause more than 14,000 deaths per year in the U.S. alone.
About Rosetta Cancer Testing Services
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). The Rosetta Lung Cancer Test accurately identifies the four main subtypes of lung cancer using small amounts of tumor cells. The Rosetta Kidney Cancer Testaccurately 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, 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. In addition to its proprietary products, the Company markets the Rosetta Genomics PGxOne test and the EGFR and KRAS sequencing services for Admera Health, as well as Precipio’s oncology tests, which include bone marrow and peripheral blood testing for hematological malignancies, such as leukemias and lymphomas.
