Lixte Biotechnology Announces Issuance of U.S. Patent for Lead Anti-Cancer Compound

EAST SETAUKET, N.Y., Sept. 22, 2011 /PRNewswire/ -- John S. Kovach, M.D., Chair, Board of Directors and CEO of Lixte Biotechnology Holdings, Inc. (LIXT.PK), announces that the United States Patent and Trademark Office awarded a patent on its lead compound, LB-100, as well as a number of structurally related compounds, which has shown promising anti-cancer activity. Patent applications on these compounds are pending world wide. Lixte is presently completing pre-clinical studies of LB-100 in preparation for submitting an application to the Food and Drug Administration to conduct Phase I trials.

John Kovach, MD, founder and president of Lixte said, "We are extremely pleased that that LB-100 and several structurally related compounds have been recognized as novel potential anti-cancer compounds. LB-100 is an anti-cancer compound, which appears to prevent cancer cells from defending themselves against standard types of cancer treatments. In pre-clinical animal model systems, LB-100 enhances the killing of cancer cells by several widely used anti-cancer drugs as well as radiation treatments. If the improved anti-cancer activity of LB-100 combined with conventional anti-cancer treatments seen in animals is borne out against human cancers without undue toxicity, we hope that LB-100 may be associated with meaningful benefit to patients with several types of cancer."

About Lixte Biotechnology Holdings, Inc.

Lixte is a biotechnology company engaged in development of improved treatments for cancer and methods for detecting cancer. Lixte was created to capitalize on opportunities to develop low cost, specific and sensitive tests for the early detection of cancers. Over the past six years, however, the Company has evolved into what is now primarily a cancer drug discovery company, using biomarker technology to develop new potentially more effective anti-cancer drugs.

The Company is developing new treatments for several cancers for which better treatments are urgently needed. The primary focus is on the most common and most aggressive type of brain cancer of adults, glioblastoma multiforme ("GBM"). The research on brain tumors is being conducted with the National Institute of Neurological Disorders and Stroke ("NINDS") of the National Institutes of Health ("NIH") under a Cooperative Research and Development Agreement ("CRADA").

The Company expanded the scope of its program to other cancers of neural tissue (nerve and brain), including medulloblastoma, the most common brain tumor of children, and neuroblastoma, the most common cancer of children, and to other cancers of adults including sarcomas, melanomas, and breast cancer
