Xenomics Executives Discuss Proprietary Breakthrough HIV Diagnostic Technology in Audio Interview with BiomedDiscoveries.com

Dr. David Tomei and Dr. Randy White Detail Research Results in Xenomics' Unique Trans-renal DNA Detection Platform


LOS ANGELES, April 29, 2005 (PRIMEZONE) -- BiomedDiscoveries.com, http://www.BiomedDiscoveries.com, the online source for exclusive investor information in the biotechnology sector, has announced the availability of an online interview with Xenomics Chairman and founder Dr. David Tomei, and Dr. Randy White, CEO of Xenomics (OTCBB:XNOM), a molecular diagnostics company.

In the audio interview, Dr. Tomei provides an overview of Xenomics' revolutionary HIV-DNA detection methodology using the Company's proprietary trans-renal DNA (Tr-DNA) technology. Scientists from Xenomics were the first to report that fragments of DNA from inside the body cross the kidney barrier and can be detected in urine. The Company is applying this discovery to the development of tests for prenatal genetic testing and to detect infectious disease and other conditions using simple, inexpensive and completely non-invasive urine sample testing.

Xenomics has recently reported on the ability of its proprietary Tr-DNA to detect HIV DNA in the urine of HIV-positive patients, potentially enabling additional diagnostic information for physicians treating AIDS patients with residual disease where traditional viral load testing is barely detectable, or in many cases undetectable. "The sensitivity of our development-stage test is capable of detecting as few as five viral particles, or genome equivalents, in the urine of treated AIDS patients. As we continue our development we expect that sensitivity to increase," said Dr. Tomei.

In collaboration with the Spallanzani Institute in Rome, a large AIDS treatment center in Italy with more than 4,000 AIDS patients, the Company is preparing to start clinical studies, the next phase in commercial development of their technologies. "These clinical studies are necessary to increase the number of patients involved so that we can obtain more information about how patients respond to therapy, and of course how the Tr-DNA testing can track the patients' response," said Dr. Tomei. "We're in the process now of what they call 'optimizing the method' -- increasing its efficiency and accuracy. We're looking forward to very high sensitivity that will approach 100%."

Dr. White discussed the size of the potential markets for this non-invasive method for early and highly sensitive detection of HIV-DNA, along with the unique capabilities of the Xenomics technology to monitor for residual HIV disease in patients that have a viral load too low to be detectable with current blood test methods.

About Xenomics, Inc.

Xenomics is a molecular diagnostic company that focuses on the development of DNA-based tests using Transrenal DNA (Tr-DNA). Xenomics' patented technology uses safe and simple urine collection and can be applied to a broad range of applications, including prenatal testing, tumor detection and monitoring, tissue transplantation, infectious disease detection, genetic testing for forensic identity determination, drug development, and research to counter bioterrorism. Scientists from Xenomics were the first to report that fragments of DNA from normal cell death cross the kidney barrier and can be detected in urine. The Company believes that its technology will open significant new markets in the molecular diagnostics field. Xenomics has three issued U.S. patents covering different applications of the technology for molecular diagnostics and genetic testing and a pending European patent for the same applications. The Company has organized a joint venture to conduct research on infectious disease detection with the National Institute for Infectious Diseases (Instituto Nazionale per le Malattie Infettive "Lazarus Spallanzani") in Rome, in the form of a new R&D company called SpaXen Italia, S.R.L.
