Lixte Biotechnology Announces the Initial Trading of Its Common Stock Under the Symbol: LIXT

EAST SETAUKET, N.Y., Sept. 24 /PRNewswire-FirstCall/ -- Lixte Biotechnology Holdings, Inc. today announced the trading of its common shares on the Over-The-Counter Bulletin Board under the Symbol LIXT.

Commenting on this important milestone, President and CEO John S. Kovach, M.D. stated, “We believe that being a publicly traded company will enable us to pursue funding opportunities that were not available to us as a private company. Having access to the capital markets is important at this stage of Lixte’s development. Over the coming months our strategy is to continue with our research under a Cooperative Research and Development Agreement (CRADA) with the National Institute of Neurological Disorders and Stroke, National Institutes of Health (NIH), while at the same time exploring other cancer research opportunities that Lixte is developing independently.”

About Lixte Biotechnology Holdings, Inc.:

Lixte Biotechnology Holdings, Inc. (Lixte) is a cancer therapeutics and diagnostics company. Founded as a biomarker-diagnostics company in 2005, the company develops new chemotherapy drugs targeting molecular abnormalities of common human cancers. Over the past year, based on the discovery of a new biomarker for brain cancers by collaborators at NIH, the company is developing new drugs for the treatment of glioblastoma multiforme (GBM), the most common and most aggressive type of primary brain cancer in adults and, to a much lesser extent, in children.

GBM occurs annually in 20,000 to 25,000 adults in the United States and in a comparable number of individuals in Europe. At present, there is no curative treatment known for this disease. Standard treatment involves surgery, radiation and the use of one or more chemotherapeutic agents at the time of initial treatment. At relapse, which occurs in essentially all patients, the present standard treatment is a drug, Temozolomide, that is associated with a modest increase in life span measured in months. Thus, there is an urgent need for more effective treatments for this disease.

Over the next year, as part of its collaboration with NIH, the company will complete the determination of the effectiveness of lead compounds from each of two different classes of drugs developed by Lixte that are active against GBM in the test tube. Initial studies showed that two different compounds have anti-tumor activity in a mouse model. The next steps will be detailed characterization of the anti-tumor activity of these drugs in animal models of human GBM and description of their pharmacologic behavior and metabolism. Subsequently, the toxicity profiles of active drugs will be determined in pre-clinical toxicology studies. Should the results of the foregoing tests and studies prove successful, we hope to satisfy all requirements of the FDA for approval of, at least, one lead compound for evaluation in Phase I trials in late 2008 or early 2009. Lixte will also evaluate the anti-cancer activity of its new compounds against two life- threatening cancers of children, neuroblastoma and medulloblastoma, and against several common cancers of adults in addition to GBM.
