EAST SETAUKET, NY, June 25, 2019 (GLOBE NEWSWIRE) -- Lixte Biotechnology Holdings, Inc. (OTCQB: LIXT) noted that a group of neuroscientists in China and Japan reported that Lixte’s lead clinical compound, LB-100, improved muscle strength, movement coordination and learning in a mouse model of Angelman syndrome (AS), a rare disease affecting 1/12,000 to 1/20,000 persons in the US (Wang et al., Proceedings of the National Academy of Science, June 3, 2019). This research reportedly involved Lixte’s proprietary compound, but Lixte and its principals are not associated with this research.
Dr. John S. Kovach, CEO of Lixte, said “AS patients have a constellation of signs and symptoms that may include intellectual and speech limitation, difficulty moving or balancing, frequent smiling and laughter, seizures, rigid movements, hyperactivity and sleep disorders. Generally, there is no family history and most AS patients have a normal life span. Mice genetically modified to have reduced function of the UBE3A gene have features of human AS including movement disorder, seizure phenomena, and cognitive impairment as well as abnormalities in structural features of brain cells. In their publication, Wang and colleagues report that they found that brain tissue of AS mice has increased concentrations of protein phosphatase 2A (PP2A), a molecular target of Lixte’s investigational compound, LB-100. They report showing that systemic administration of LB-100 to young AS mice improved their movement disorder and the structure and function of their abnormal brain cells. This is a completely unanticipated finding. Whether LB-100 could possibly be of therapeutic benefit in AS is a question Lixte is discussing with experts in the field.”
Dr. Kovach continued “apart from the intriguing insight into a possible therapeutic approach to the symptoms of Angelman’s syndrome, Lixte is encouraged by the study of Wang and colleagues because as reported it indicates that (some) LB-100 penetrates the brain, at least in mice with AS. In preclinical studies, LB-100 potentiates the effectiveness of standard treatments for several types of central nervous system cancers including glioblastoma multiforme, the most aggressive brain tumor of adults. However, it is not known whether LB-100 penetrates the human brain.
While the Wang publication is suggestive, as Lixte recently reported, the National Cancer Institute (NCI) is conducting a pharmacologic study to definitively determine if LB-100 enters the brain and tumor tissue in patients having surgical removal of recurrent glioblastomas (clinical trials registry: NCT03027388). If so, there will be a sound rationale for investigating whether the addition of LB-100 improves the efficacy of standard treatment for glioblastoma and potentially other brain cancers.” For patients interested in enrolling in the NCI clinical study, please contact NCI’s toll-free number 1-800-4-Cancer (1-800-422-6237) (TTY: 1-800-332-8615) and/or the website: https://trials.cancer.gov.
