Calypte's Aware(TM) HIV-1/2 BSP Test Receives Zimbabwe Approval
Regulatory Trials Of Aware(TM) BSP Generate 100% Accuracy
LAKE OSWEGO, Ore., Sept. 15 /PRNewswire-FirstCall/ -- Calypte Biomedical Corporation (Amex: HIV) today announced that the Medical Laboratory & Clinical Scientists Council of Zimbabwe has issued notification that the Calypte Aware(TM) HIV-1/2 BSP rapid (blood) test has been successfully evaluated and cleared for commercial sale in Zimbabwe.
The Calypte Aware HIV-1/2 BSP rapid test was evaluated under the direction of the Medical Laboratory & Clinical Scientists Council of Zimbabwe on over 1,000 samples. Roughly half of the samples were archived samples from the national reference panel and the other half were collected prospectively from clinical patients, blood donors, and attendees at VCT (Voluntary testing and Counseling) sites. The clinical trial of the Aware HIV-1/2 BSP rapid test included 1,005 subjects; 224 of whom were infected and 781 of whom were uninfected. The table below summarizes the performance of the rapid tests.

Archived Samples (500) 100.0% 100.0% 100.0%
Prospective Samples (505) 100.0% 100.0% 100.0%
Sensitivity is a measure of the number of infected subjects correctly identified as positive. Specificity is a measure of the number of uninfected subjects correctly identified as negative. Accuracy is a composite measure of how many of the test subjects were correctly classified as infected or uninfected.
Calypte and its distributor, National Diagnostics, are now working with authorities on a process by which Aware HIV-1/2 OMT (oral fluid) and HIV-1/2 U (urine) rapid assays can be evaluated. Zimbabwe has not had the opportunity to field test non-blood HIV screening tests before, and its standard approach to evaluate HIV antibody tests is not appropriate for samples such as urine and oral fluid. The authorities are examining various proposals for such an evaluation.
Dr. Richard George, President and CEO of Calypte said, "We are delighted that the BSP test has passed yet another regulatory hurdle, and we now look forward to working with National Diagnostics, our distributor in Zimbabwe, to get the product commercially launched. In parallel we hope to complete the evaluation using the Company's technology in Urine and Oral fluid."
Tony Mariani, President of National Diagnostics, added, "We are extremely pleased with the exceptional results achieved by the Aware BSP HIV-1/2 kit in its evaluation phases. We look forward to our venture with Calypte in the marketing and distribution of this kit throughout Zimbabwe. Since our establishment in 1991, National Diagnostics has imported and distributed a wide range of diagnostic reagents, and this project promises to be one of the most important undertakings in our company's history".
Zimbabwe, with a population of just under 13 million, has an estimated 1.8 million HIV infections, according to the UNAIDS 2004 Report on the Global AIDS Epidemic, ranking as the 3rd largest prevalence in Africa today.
Aware(TM) BSP is a twenty-minute rapid test designed to detect HIV antibodies in whole blood, serum, or plasma. It is one test in a line of three such assays, the other two being designed to detect HIV antibodies in oral fluid and urine.
