CombiMatrix Announces the Acceptance of Its Multi-Institute Study On the Use of HemeScan for CLL by Journal, Expert Opinions in Molecular Diagnostics

Publication Represents First Peer-Reviewed Study of a Commercial Clinically Validated Diagnostic Array CGH-Based Test for Cancer


MUKILTEO, Wash., June 4, 2008 (PRIME NEWSWIRE) -- CombiMatrix Corporation (Nasdaq:CBMX) announced today that its subsidiary, Combimatrix Molecular Diagnostics (CMDX), has results from a multi-institute evaluation of its HemeScan(tm) test for CLL that were accepted for publication by the journal, Expert Opinions in Molecular Diagnostics (2008) 2(6): 1-10. The study, which was led by Dr. Shelly Gunn, Medical Director of CMDX, and which included collaborators from the prestigious M.D. Anderson Cancer Center, Texas, the Netherlands Cancer Institute, Amsterdam, and the University of Texas Health Science Center, San Antonio, evaluated over 170 patients with chronic lymphocytic leukemia (CLL) by the HemeScan test. The results of the study concluded that CMDX's HemeScan test is a powerful and cost-effective tool for genome-wide risk assessment in the clinical evaluation of CLL.

"This article is the first peer-reviewed publication of the clinical evaluation of an array CGH (Comparative Genomic Hybridization) diagnostics test addressing cancer. CombiMatrix is pleased to be the first to have launched a CGH array for cancer and now, is pleased to have completed this clinical study, which enables another first for the company," noted Dr. Mansoor Mohammed, President and CEO of CombiMatrix Molecular Diagnostics. "We are also pleased to have completed this study in collaboration with several leading cancer researchers and their institutes. This study is the first in what we anticipate to be a series of publications, which will clearly establish the clinical utility of CMDX's suite of oncology tests."

Dr. Shelly Gunn, Medical Director of CMDX, notes, "The publication of peer-reviewed studies is a hallmark of legitimizing new diagnostic tests and their concomitant platforms. Publications have set the standard for the use of new medical innovations." Dr. Gunn further adds, "I am proud to have contributed, together with Dr. Mohammed, pioneering publications documenting the use of array CGH in solving clinical diagnostic challenges, and I am equally proud to now author the first study documenting the use of this transformatory technology toward solving diagnostic challenges, in a commercial setting, for the oncology arena".

Mr. Ron Andrews, CEO of Clarient (Nasdaq:CLRT), commented, "As I have previously noted, we evaluated several leading platforms and tests before deciding upon CMDX's HemeScan test as a suitable addition to our world class portfolio of cancer diagnostics. This recent publication by CMDX validates our assessment of the HemeScan test for CLL and fits with our model of launching the most comprehensive and robust diagnostic test menu in the industry."
