The clinical trial is sponsored by The University of Texas &#8211; MD Anderson Cancer Center and will be conducted at MD Anderson and will also be open at Northwestern University\u2019s Robert H. Lurie Comprehensive Cancer Center. LIXTE will provide LB-100; GSK will provide dostarlimab and financial support for the clinical trial.<\/p>\n<p align=\"justify\">The clinical trial is based on the observation of longer survival of patients with OCCC treated with immunotherapy whose cancer cells have an acquired gene mutation resulting in a reduction in PP2A. This finding was reported by the lead clinical investigators of this new trial<sup>1<\/sup>: Amir Jazaeri MD, Professor of Gynecologic Oncology at MD Anderson, and Emily Hinchcliff, MD, MPH, Assistant Professor of Obstetrics and Gynecology at Northwestern University Feinberg School of Medicine. The observation by Drs. Jazaeri and Hinchcliff, that a genetically acquired reduction in PP2A enhances sensitivity to immunotherapy, raises the possibility that reducing PP2A pharmacologically with LB-100 will enhance the anti-tumor effect of the PD-1 blocking monoclonal antibody dostarlimab in patients with OCCC lacking the genetic reduction in PP2A.<\/p>\n<p align=\"justify\">John S. Kovach, M.D., LIXTE\u2019s founder and Chief Executive Officer, said, \u201cPreclinical data supports the idea that LB-100 enhances the efficacy of PD-1 therapy.<sup>1<\/sup> Clinical data also supports this idea, in that patients with ovarian clear cell carcinoma with dysfunctional PP2A due to somatic mutations in PPP2R1A have shown dramatically longer survival after treatment with immune checkpoint blockers.\u201d<\/p>\n<p align=\"justify\">Dr. Hinchcliff, said, \u201cOCCC is a comparatively chemotherapy resistant disease and therefore has very limited options for treatment. This clinical trial is an exciting alternative approach that leverages the potential synergy between these two agents and is aiming to improve the impact immunotherapy may have for these patients.\u201d<\/p>\n<p>\n        <strong>About LIXTE Biotechnology Holdings<\/strong><br \/>\n        <strong>, Inc.<\/strong>\n      <\/p>\n<p align=\"justify\">\n        <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=JS4nBo-l28BDz1Zfd2KKUpj0koe8jAhR1se4kIVsuTApXmQ2PfLcDvi1eQogP5n7OXN0J2vDcVNRN6s3TJGAzRxh7ItULxJw7DLLg0aCPYt-onIyEaYKSb0TBT5nEGFfQYec8XYpwQNqH8XofXKZVeokqxbiXPbNU3FPIoC-P_PSoHnUpmKGH2h-paeaSnTxKjUhtCimb9xGOw6epwxxT-wgF_rEskWYVdFbwGgBNSDj-pK-JjU1zm5aFDHOrFNzhjKrOAMY7Gp74A38DgVnLRFtQUolDp0YMRq-LsEbXyfBb9fbzoVTWawCpEOOt9WK\" rel=\"nofollow noopener\" target=\"_blank\">LIXTE Biotechnology Holdings, Inc.<\/a>\u00a0is a clinical-stage pharmaceutical company focused on new targets for cancer drug development and developing and commercializing cancer therapies.
