Response Biomedical Files for US FDA 510(k) Market Clearance of Rapid Influenza A+B Test

VANCOUVER, June 11 (HSMN NewsFeed) - Response Biomedical Corporation (TSX-V: RBM, OTCBB: RPBIF) announced today that it has filed a US Food and Drug Administration (FDA) 510(k) submission seeking clearance to market a rapid Influenza A+B test.

The test manufactured by Response will run on the RAMP® platform and will be marketed and sold exclusively by 3M Health Care as the 3M(TM) Rapid Detection Flu A+B Test. It is a qualitative immunochromatographic assay indicated for use as an in vitro diagnostic product used with the 3M(TM) Rapid Detection Reader (manufactured by Response) to identify the presence of Influenza A and Influenza B (Flu A and Flu B) nucleoprotein antigen in nasal wash, nasal swab, nasopharyngeal aspirate and nasopharyngeal swab specimens. Measurement of Influenza A and Influenza B aids in the rapid differential diagnosis of influenza viral infections through this point-of-care (POC) test.

POC or "near-patient" testing allows for diagnostic assays to be performed at the site of patient care delivery. POC testing provides for rapid clinical decision-making by reducing the time spent ordering tests, collecting and transporting samples, as well as retrieving data.

"Once again, RAMP has demonstrated exceptional performance," said Bill Radvak, President and CEO. "Attendance at several recent trade shows has seen lots of excitement about the RAMP Reader's ability to not only give a positive indication of Flu But also delineate between Flu A and B. This is seen by many as being superior to our competitors' manual strips." Both companies hope to make this important test commercially available before the next U.S. flu season.

About Flu

Flu is a contagious disease caused by the influenza virus. Influenza viruses are classified into types A, B and C. Type A is a reportable disease, and is the most common and usually causes the most serious epidemics. Type B outbreaks also can cause epidemics, but the disease it produces is generally milder than that caused by type A. Type C viruses have never been connected with a large epidemic. Flu A is most prevalent and causes 87 percent of infections with the remaining 13 percent of reported cases being Flu B.

Every year, 5 percent to 20 percent of the U.S. population suffers from flu. Approximately 36,000 people infected with the flu die each year, and over 200,000 are admitted to hospital. During an average flu season, flu and flu related complications are the sixth leading cause of death in the United States.

Although most people who get the flu recover within a week, some of the medical complications caused by flu infection include bacterial pneumonia, dehydration and worsening of chronic medical conditions, such as congestive heart failure, asthma or diabetes. Children may develop sinus problems and ear infections as complications from flu infections. It is these complications, rather than the symptoms of flu themselves that lead to serious concerns with rapid diagnosis of infected individuals. The Centers for Disease Control (CDC) recommend that any person at high risk for serious complications of influenza and who is within the first two days of illness onset should be treated with antiviral medications.
