LIXTE Biotechnology's PP2A Inhibitor LB-100 Aims to Overcome Cancer Treatment Resistance

LIXTE Biotechnology Holdings is advancing a first-in-class approach designed to increase the effectiveness of chemotherapy and immunotherapy across multiple cancer indications. The company's strategy centers on protein phosphatase 2A, an enzyme that plays a critical role in regulating cell growth, DNA repair, and survival signaling. In many cancers, PP2A activity enables tumor cells to recover from the damage caused by treatment, contributing to resistance and disease progression.

LIXTE's proprietary compound, LB-100, is a small-molecule PP2A inhibitor designed to temporarily disrupt these repair mechanisms at the moment when cancer cells are exposed to therapy. Preclinical research shows that this disruption can make tumor cells more vulnerable to chemotherapy and immunotherapy, increasing treatment effectiveness without introducing a new cytotoxic agent. The company has demonstrated that its first-in-class lead clinical PP2A inhibitor is well-tolerated in cancer patients at doses associated with anti-cancer activity.

Based on extensive published preclinical data available at https://www.lixte.com, LB-100 has the potential to significantly enhance chemotherapies and immunotherapies and improve outcomes for patients with cancer. The lead compound is part of a pioneering effort in an entirely new field of cancer biology called activation lethality that is advancing a new treatment paradigm. This innovative approach is covered by a comprehensive patent portfolio, providing intellectual property protection for the company's discoveries.

Proof-of-concept clinical trials are currently in progress for ovarian clear cell carcinoma and metastatic colon cancer, representing important steps toward validating the therapeutic potential of this approach. The company's focus on enhancing established cancer therapies by targeting a fundamental biological pathway involved in tumor survival and resistance represents a strategic shift from developing standalone treatments to improving existing therapeutic modalities.

This development matters because overcoming treatment resistance remains one of the most significant challenges in oncology, with many patients experiencing disease progression despite initial response to therapy. By targeting PP2A, LIXTE addresses a mechanism that enables cancer cells to survive therapeutic assault, potentially extending the effectiveness of current treatments across multiple cancer types. The implications extend beyond individual compounds to potentially establishing new combination therapy approaches that could transform standard cancer treatment protocols.

Forward-looking statements in investment communications are subject to various factors beyond management's control, including risks detailed in the company's SEC filings available at http://IBN.fm/Disclaimer. The company's progress in clinical trials will provide critical data on whether this novel approach can translate from promising preclinical results to meaningful clinical benefits for cancer patients facing treatment-resistant disease.
