TriPath Imaging Receives FDA 510(k) Clearance for Ki-67 Application for Ventana Image Analysis System

BURLINGTON, N.C., and TUCSON, Ariz., April 17 (HSMN NewsFeed) -- TriPath Imaging Inc. (Nasdaq: TPTH ) and Ventana Medical Systems, Inc. (Nasdaq: VMSI ), announced today that TriPath Imaging has received 510(k) clearance from the U.S. Food and Drug Administration for the Ventana Image Analysis System (VIAS(TM)) when used with tissues stained for Ki-67. In 2005, the Companies announced 510(k) clearances for VIAS when used with the Ventana Estrogen Receptor (ER), Progesterone Receptor (PR) and HER-2/neu assays.

Ki-67 is a cell proliferation biomarker which is employed by pathologists as an adjunct to histopathology and is used to assist with diagnosis and the prognostic assessment of cancer. Precise quantitative measurement of Ki-67 expression in breast biopsy samples may be used to calculate the rate of cell proliferation by measuring the percentage of tumor cells that are actively dividing and, therefore, producing more cancer cells. Research studies have shown a significant correlation between high proliferation rates and shorter disease free and overall survival. VIAS is ideally suited to provide this level of biomarker quantification.

"FDA clearance for the analysis of Ki-67 clearly increases the clinical utility of VIAS as an aid to the anatomical pathologist. This is the first time the Ki-67 marker has been cleared by the FDA for use with an image analysis system," said Paul R. Sohmer, M.D., Chairman, President, and CEO of TriPath Imaging. "We expect to continue to further expand the application menu supported by VIAS with additional 510(k) applications."

"We are pleased that TriPath Imaging has obtained this clearance," stated Christopher Gleeson, President and Chief Executive Officer of Ventana Medical Systems. "This expands our VIAS menu and, together with the previous clearances for ER, PR and HER-2/neu, enables us to provide further value to pathologists."
