About Champions Biotechnology, Inc.

       Champions Biotechnology is a twenty two year old publicly traded company that beginning in January 2007, changed its business direction to focus on biotechnology. The Company is engaged in the acquisition and early stage development of a portfolio of new therapeutic drug candidates, in the acquisition and development of novel technologies and in providing administrative services in the field of oncology that the Company hopes will improve methods of and approaches to disease treatment.

       Champions Biotechnology plans to develop a portfolio of new therapeutic drug candidates through pre-clinical trials and possibly early phase ("first in man") clinical trials. If therapeutic drug candidates reach this early stage of development, Champions Biotechnology intends to sell, partner with, or license them to pharmaceutical and/or biotechnology companies, as appropriate. Management believes this strategy will enable Champions Biotechnology to leverage the competencies of these partners or licensees to maximize Champions Biotechnology’s return on investment in a relatively short time frame. Champions Biotechnology believes that this model is unlike that of typical new biotechnology companies that look to bring the process of drug development through all phases of discovery, development, regulatory approvals, and marketing, which requires a very large financial commitment and a long time, typically more than a decade, to realize.

       In February 2007, Champions Biotechnology acquired the patent rights to two Benzoylphenylurea (BPU) sulfur analog compounds that have shown promising potent activity against prostate and pancreatic cancer cell lines.

       In May 2007, Champions Biotechnology acquired Biomerk Inc. a company focused on generating a novel preclinical platform of human cancer tumor immune-deficient mice xenografts (Biomerk Tumorgrafts™). Biomerk Tumorgrafts™, unlike standard cell line derived xenografts, are implanted directly from primary human cancer tumors and never passaged in cell tissue culture. Champions Biotechnology believes that these xenografts more closely reflect human cancer biology and are more predictive of clinical outcome. Champions Biotechnology believes that it as well as biotechnology and pharmaceutical companies, as part of their drug discovery and post marketing efforts, may benefit from utilizing services that are more predictive and that might provide for a faster and less expensive path for drug approval. These services will utilize Biomerk Tumorgrafts™ to evaluate tumor sensitivity/resistance to various single and combination standard and novel chemotherapy agents.

Champions Biotechnology generally uses words such as "believe," "may," "could," "will," "intend," "expect," "anticipate," "plan," and similar expressions to identify forward-looking statements.

Although Champions Biotechnology believes the expectations reflected in the forward-looking statements are reasonable, they relate only to events as of the date on which the statements are made, and Champions Biotechnology’s future results, levels of activity, performance or achievements may not meet these expectations. Champions Biotechnology does not intend to update any of the forward-looking statements after the date of this press release to conform these statements to actual results or to changes in Champions Biotechnology’s expectations, except as required by law.
