LIXTE has demonstrated that LB-100, its lead compound and first-in-class lead clinical PP2A inhibitor, is well-tolerated in cancer patients at doses associated with anti-cancer activity. Based on published preclinical data, LB-100 has the potential to significantly enhance chemotherapies and immunotherapies and improve outcomes for patients with cancer. It is part of a pioneering effort in an entirely new field of cancer biology – activation lethality – that is advancing a new treatment paradigm. LIXTE&#39;s novel approach is covered by a comprehensive patent portfolio, with proof-of-concept clinical trials currently in progress for Ovarian Clear Cell Carcinoma, Metastatic Colon Cancer and Advanced Soft Tissue Sarcoma.
