Chinese State FDA Completes Technical Review Of Calypte Biomedical's Oral HIV Test Application

Calypte Biomedical Corporation (OTCBB: CBMC), a developer, manufacturer and marketer of HIV diagnostic tests, announced that the Chinese State Food and Drug Administration ("SFDA") has notified Calypte's Chinese manufacturing subsidiary, Beijing Marr Bio-pharmaceutical Co., Ltd., ("Beijing Marr") that the technical review of its Aware™ HIV-1/2 OMT rapid oral test product application has been completed. Pending the SFDA's review of conformity to product standard documents and labeling to applicable regulations, the application will progress to the concluding administrative approval.

Roger I. Gale, Calypte's President and Chief Executive Officer, stated, "This is a major milestone in a long and difficult approval process. We are extremely pleased that the SFDA has determined that our scientific data has met their criteria, and that we are now moving into the final phase of the registration process. We believe that in meeting the technical standards established by the SFDA, we have demonstrated to them the high quality of our product."

Dr. Ronald W. Mink, Calypte's Chief Science Officer, commented, "The technical review is considered the most challenging and lengthy portion of the SFDA review process, and is the penultimate milestone in the approval process. We are absolutely delighted that we have overcome what is arguably the highest hurdle in the approval process, and are ready to move into the final administrative stage."

David K. Harris, Beijing Marr's Chief Executive Officer stated that, "The notice from the SFDA is of paramount importance and indicates that the substantive content of the application and the technology itself have met with the acceptance of the SFDA and are acceptable for the Chinese market. Nearing the end of an arduous approval process, we are very proud to see this recognition of years of hard work in developing the AwareTM HIV-1/2 OMT product."

Calypte operates in China through Beijing Marr, a joint venture between Calypte and the Marr Group established to manufacture Calypte's Aware™ line of rapid HIV tests, including the Aware™ HIV-1/2 OMT product for both the Chinese and international markets. The Aware™ HIV-1/2 OMT product is a rapid test using oral fluid to diagnose HIV-1 or HIV-2 infection in as little as 20 minutes with an accuracy comparable to that of U.S. FDA approved blood based laboratory HIV EIA tests.
