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 (GMB), 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 a lead compound from each of two different classes of drugs developed by Lixte that are active against GBM in the test tube. The next step will be characterization of the anti-tumor activity of these drugs in an animal model of human GBM and description of their pharmacologic behavior and metabolism in animals. 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.
