CHATSWORTH, Calif., Oct 26, 2009 (GlobeNewswire via COMTEX) -- IRIS | Quote | Chart | News | PowerRating -- IRIS International, Inc. (Nasdaq:IRIS) announced today that it has received Institutional Review Board (IRB) approvals from Duke University Medical Center, Memorial Sloan Kettering Cancer Institute, Eastern Virginia Medical School and the University of Washington Medical Center to immediately begin a multi-center 300 patient retrospective randomized clinical study utilizing its NADiA(TM) ProsVue(TM) ultra sensitive prostate-specific antigen diagnostic assay.

The NADiA(TM) ProsVue(TM) assay will be independently used in this study to assist the Company in furthering the hypothesis that NADiA(TM) ProsVue(TM) can be used to prognosticate post radical prostatectomy patients with low risk of prostate cancer recurrence. As a first priority, IRIS plans to collect its NADiA ProsVue data using real time polymerase chain reaction (RT-PCR) instrumentation that is already cleared for diagnostics use, as required by the FDA. The testing and analysis of 300 patients with serially collected blood samples, retained over an eight year period, is expected to be completed in approximately two months with the results to be incorporated into a FDA 510(k) application, which IRIS expects to submit late in the fourth quarter 2009. Following clearance of this first submission, IRIS plans to re-validate and submit NADiA(TM) ProsVue(TM) for sub-sequent FDA clearances using other RT-PCR systems upon the attainment of FDA clearance by the manufacturers of those devices.

"We are pleased with the initiation of this larger clinical study which follows an earlier 30 patient study, on which we base the prognostic hypothesis for our NADiA(TM) ProsVue(TM) in vitro ultra sensitive diagnostic assay," stated Cesar Garcia, Chairman, President and CEO of IRIS International. "We have already begun to receive the necessary retained patient samples for this larger clinical study. Upon successful conclusion of the experimental analysis, IRIS is planning to submit a 510(k) application with the FDA seeking clearance of a prognostic claim for its NADiA(TM) ProsVue(TM) as an in-vitro diagnostic assay intended to be used in conjunction with clinical evaluation as an aid in predicting risk for prostate cancer recurrence after radical prostatectomy. It is our objective to make our NADiA platform available in as many RT-PCR instruments as possible," he said.

"The results of two prior smaller clinical studies have shown that NADiA(TM) ProsVue(TM) enables the stratification of post-prostatectomy patients, thus supporting a prognostic use that is an enhancement of the intended use proposed in our initial 510(k) submission. We expect the results of this larger study to be consistent with our earlier findings," stated Dr. Thomas Adams, Corporate Vice President and Chief Technology Officer of IRIS. "We believe the ability to identify post-prostatectomy patients with low risk of prostate cancer recurrence would have substantial clinical and economic benefits that should be entitled to significant reimbursement," he added.

In a previously announced retrospective study of stored leftover serum of 85 post-prostatectomy patients, NADiA(TM) ProsVue(TM) detected levels of PSA after radical prostatectomy that were undetectable using conventional ultra sensitive assays. In this study, the NADiA(TM) ProsVue(TM) assay detected a rise of PSA concentration on an average 2-1/2 years before tPSA values reached 100 pg/mL (0.1ng/mL), the sensitivity level of conventional PSA assays.

According to the American Cancer Society there were an estimated 186,320 new cases of prostate cancer in the U.S. in 2008, with 28,660 deaths occurring from prostate cancer in the U.S. alone, making it the second leading cause of cancer death in men. There are currently approximately two million men in the U.S. who have undergone radical prostatectomy with another 155,000 new procedures performed each year.
