Lixte Biotechnology Holdings Announces Filing of a New Patent Application for Cancer Therapy Based on Targeting a Biomarker by Novel Investigational Agents

EAST SETAUKET, N.Y., Aug. 19 /PRNewswire-FirstCall/ -- Lixte Biotechnology Holdings, Inc. (OTC Bulletin Board: LIXT) announced today that the National Institute of Neurological Disorders and Stroke (NINDS), National Institutes of Health (NIH) and Lixte filed a joint patent application identifying a biomarker, present in many common cancers, that is a target of drugs being evaluated by Lixte and NINDS for the treatment of brain tumors.

Dr. John S. Kovach, President and CEO of Lixte, said, "Studies with the research team at the Molecular Pathogenesis Unit, Surgical Neurology Branch, NINDS, identified a biomarker that appears to be preferentially targeted by novel anti-cancer drugs currently being evaluated by NINDS and Lixte as new treatments for human brain tumors. Molecular studies revealed that these drugs alter the state of this biomarker in a way that leads to the death of cancer cells. Since the biomarker appears to be important to the survival of several human cancers in addition to brain cancers, studies will be done to determine the effectiveness of targeting the biomarker in other tumor types and as a guide to drug discovery of new anti-cancer compounds."
