Lixte Biotechnology Holdings, Inc.<\/strong> (NASDAQ: LIXT) shares jumped about 70% after the biotech company announced that the in principle studies its lead clinical compound, LB-100, a protein phosphatase (PP2A) inhibitor, was found to increase the responsiveness of diverse cancers to immunotherapy.<\/p>\n\n\n\n

\u201cRecent advances in therapy with immune checkpoint inhibitors have been a true breakthrough in the development of more effective and less toxic treatment for many cancers. Unfortunately, most cancer patients do not respond to immunotherapy. There are widespread efforts to find pharmacologic and\/or immunologic ways to turn unresponsive (\u2018cold\u2019) tumors into responsive (\u2018hot\u2019) tumors. Cancers with a molecular abnormality termed microsatellite-instability (MSI) stemming from a defect in a DNA repair enzyme are generally \u2018hot\u2019 tumors, that is, tumors responsive to immunotherapy. Yen and colleagues now report that pharmacologic inhibition of PP2A by LB-100 modifies two distinct molecular pathways resulting in conversion of microsatellite stable (MSS) tumors into MSI tumors sensitive immune checkpoint blockade therapy.\u201d<\/p>Lixte\u2019s founder and CEO, John S. Kovach M.D<\/cite><\/blockquote>\n\n\n\n

In Nature Communications<\/a> (15 Dec 2021), lead author Yu-Ting Yen and colleagues at the China Medical University and Hospital, Taichung, Taiwan reported that treatment with LB-100 is associated with new antigen production, tumor infiltration of cytotoxic T cells, and enhanced responsiveness to immune checkpoint blockade in mouse models of colorectal, triple-negative breast, and pancreatic cancer.Dr. Kovach concluded: \u201cThe results of Yen et al. raise the possibility that the addition of LB-100 to immunotherapy may be a simple way to convert \u2018cold\u2019 into \u2018hot\u2019 tumors, thereby increasing the percentage of patients responsive to immunotherapy. Lixte recently initiated a clinical trial in patients with previously untreated extensive stage small cell lung cancer in which LB-100 is first added to chemotherapy and an immune checkpoint blocker and then administered with the immune blocker alone in the maintenance phase of treatment (NCT04560972<\/a>). Lixte is interested in collaborative studies designed to determine whether LB-100 broadly enhances the benefit of immunotherapy. Immune checkpoint blockers are now approved for treatment of at least 20 cancer types.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Lixte Biotechnology Holdings, Inc.
