Response Biomedical Announces First Commercial Sales Of RAMP NT-proBNP Test For Diagnosis Of Congestive Heart Failure

VANCOUVER, Jan. 23 /PRNewswire-FirstCall/ - Response Biomedical Corporation announced today the European commercial launch of the NT-proBNP Test for the diagnosis of congestive heart failure (CHF). More than 25 RAMP Systems, as well as NT-proBNP and Troponin I Tests, have been sold to hospitals, clinics and medical labs in France, through ALL DIAG S.A, the Company’s distributor in France. The European CE Declaration to market the NT-proBNP Test in Europe was completed in late December 2006. Response Biomedical has thirteen local distributors in Europe, marketing the RAMP cardiovascular products.

“We are very pleased to see such a strong start in our first month of sales of the NT-proBNP Test in Europe,” said Bill Radvak, President and CEO. “We have built a strong menu of tests in the cardiovascular space and we believe NT-proBNP is a critical component of our expanding portfolio. We saw compelling results from our clinical trial conducted in 2006 and customers in France have subsequently shown great interest in becoming the first to use this test for CHF. The RAMP Platform has the accuracy one expects from a central lab, combined with the speed and convenience of point-of-care testing. We also filed the US FDA 510(k) market clearance in December 2006. We look forward to introducing this test to an even larger market in the months to come.”

About Congestive Heart Failure

Congestive heart failure (CHF) is a condition in which the heart’s ability to pump blood at a rate sufficient to support the body’s vital needs is impaired. CHF affects nearly 17 million people worldwide, and is the single most frequent cause of hospitalization in people over 65 years. The initial diagnosis of CHF is problematic as symptoms can be associated with other pathologies such as respiratory disease and the secondary effects of obesity. According to the American Heart Association, approximately 5 million Americans are currently afflicted with CHF and 550,000 new cases are diagnosed each year. The prevalence of CHF is expected to continue increasing due to the aging population and improved survival rates of patients with other cardiovascular diseases.

About NT-proBNP

NT-proBNP is widely recognized as a definitive marker for the diagnosis of CHF. NT-proBNP is cleaved from the precursor peptide proBNP in quantities directly proportional to its biologically active counterpart BNP and in close correlation with the severity of heart failure. BNP is secreted primarily from the left ventricle in response to pressure overload and regulates blood pressure, electrolyte balance and fluid volume. BNP acts to reduce the pressure overload. Elevated levels of NT-proBNP indicate the presence of heart failure, and provide physicians with an important diagnostic tool in the early detection and management of CHF. Independent published studies show that NT-proBNP is also valuable for; risk stratification of patients with stable coronary heart disease, as a prognostic marker across the entire spectrum of cardiovascular diseases, potentially detecting early stages of CHF in the absence of clinically obvious symptoms, and for the assessment of prognosis for patients with CHF and for patients who have previously had a myocardial infarction (references available upon request). The RAMP NT-proBNP Test was developed under license from Roche Diagnostics GMbH.

About Response Biomedical

Response Biomedical develops, manufactures and markets rapid on-site diagnostic tests for use with its portable RAMP Platform for clinical and environmental applications. RAMP represents a new paradigm in diagnostics that provides high sensitivity and reliable information in minutes. It is ideally suited to both point-of-care testing and for laboratory use. The RAMP System consists of a portable fluorescent Reader and single-use, disposable Test Cartridges, and has the potential to be adapted to more than 250 medical and non-medical tests currently performed in laboratories. RAMP clinical tests are commercially available for the early detection of heart attack and congestive heart failure. The Company recently filed a submission with the US FDA for market clearance for its NT-pro BNP test, expected to be on the US market in 2007. The Company also recently announced a strategic alliance with 3M Company to commercialize rapid infectious disease tests. Clinical trials for Staphylococcus aureus and Flu A/B are expected to get underway shortly, with commercialization expected in 2007. In the non-clinical market RAMP tests are currently provided for the environmental detection of West Nile virus, and biodefense applications including the rapid on-site detection of anthrax, smallpox, ricin and botulinum toxin. Several other product applications are under development. The Company has achieved CE Marking and its Quality Management System is registered to ISO 13485: 2003 and ISO 9001: 2000.
