  • Test Identifies Patients at Reduced Risk for Prostate Cancer Clinical Recurrence After Surgery

CHATSWORTH, Calif., May 21, 2012 (GLOBE NEWSWIRE) -- IRIS International, Inc. (Nasdaq:IRIS), a leading manufacturer of automated in-vitro diagnostics systems and consumables, today announced that the Iris Personalized Medicine group is unveiling its novel prostate cancer system, NADiA® ProsVue™ at the American Urological Association (AUA) Annual Meeting in Atlanta. NADiA ProsVue, a prognostic prostate cancer test, will be showcased at the Iris Personalized Medicine booth #2530 where urologists and healthcare professionals can learn more about the test's innovative Immuno-PCR technology and clinical benefit.

The commercial domestic launch of NADiA ProsVue is underway after having received 510(k) clearance from the FDA and CE Mark approval in the fall of 2011. The company continues to work on a number of peer-reviewed publications and recently had a paper published in Clinical Chemistry, including data on NADiA ProsVue assay sensitivity, precision and reproducibility. Additional data will be presented at the upcoming 5th International Symposium on Focal Therapy and Imaging in Prostate & Kidney Cancer June 6-8, 2012 in Durham, that demonstrates NADiA ProsVue's superior ability to identify men at reduced risk for clinical recurrence compared to surgical margin data.

"We are pleased that NADiA ProsVue is being showcased to a broad audience of urologists from around the world," said César M. García, Chairman, President and Chief Executive Officer of IRIS International. "In addition, we recently initiated our Field Experience Trial (FET) which is designed to show how NADiA ProsVue impacts clinical decision-making and potentially optimizes healthcare costs while reducing patient morbidity from unnecessary adjuvant treatment post-radical prostatectomy. The FET is gaining significant interest with enrollment from both leading academic institutions as well as private urology practices."

"NADiA ProsVue could mark a significant change in the way we care for and manage prostate cancer patients," stated Judd Moul, MD, Professor and Director of the Duke Prostate Center at Duke University Medical Center. "Many men who may not be at a high risk for clinical recurrences currently receive adjuvant therapy after surgery, which often leads to complications such as impotence and incontinence. NADiA ProsVue results provide clinicians with an important new tool to help determine those patients that may not benefit from additional therapy and can avoid the effects of unnecessary treatment."

NADiA ProsVue is an in-vitro diagnostic assay for determining rate of change of serum total prostate specific antigen (tPSA) over a period of time. A retrospective clinical study of 304 patients evaluated the slope of three successive ProsVue tests over a period of at least ten months after a prostatectomy to identify prostate cancer patients with no evidence of disease or clinical progression. Recurrence of disease was determined by positive imaging, biopsy results or prostate cancer related death.

The study resulted in a negative predictive value (NPV), or the proportion of patients correctly identified as stable, of 92.7% and a positive predictive value (PPV), or proportion of patients correctly identified as recurring, of 78.0%.  Consequently, a ProsVue slope of equal to or less than 2.0 pg/mL per month in the first year following radical post-prostatectomy was highly associated with no evidence of disease over the long-term follow up.

NADiA ProsVue is available through Iris Personalized Medicine's high complexity CLIA-certified laboratory. For more information on NADiA ProsVue, please visit

About the NADiA Technology Platform          

NADiA technology, Nucleic Acid Detection Immunoassay, is a molecular diagnostics platform targeting the early detection of proteins associated with cancer and infectious diseases utilizing a novel ultra-sensitive and precise method. NADiA combines immunoassay and real-time Polymerase Chain Reaction (PCR) methodologies, or Immuno-PCR, with the potential to detect proteins with femtogram/milliliter sensitivity (10-15 gram/milliliter). As NADiA has the ability to effectively measure extremely low concentrations of proteins, which may be under the detection threshold of current immunoassay methods, it has the potential to provide better therapeutic outcomes for patients.
