LIXTE Biotechnology Holdings has announced an expansion of its collaboration with The University of Texas MD Anderson Cancer Center and pharmaceutical manufacturer GSK on an ongoing clinical trial evaluating its proprietary compound LB-100 in combination with GSK's Dostarlimab for the treatment of ovarian clear cell cancer. The trial, initiated in January 2024 and led by Amir Jazaeri, MD, at MD Anderson, has added a second site at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University under the direction of Emily M. Hinchcliff, MD, MPH, and is expected to double enrollment to 42 patients following completion of its initial 21-patient target.
The company expects data from the initial cohort to be presented in the first half of 2026. This expansion represents a significant step in evaluating a novel treatment approach for ovarian clear cell cancer, a subtype that often shows resistance to conventional therapies. The trial's growth to include Northwestern University's cancer center enhances geographic accessibility for patients and brings additional expertise to the research effort.
LIXTE's lead compound, LB-100, represents a pioneering effort in an entirely new field of cancer biology called activation lethality, which is advancing a new treatment paradigm. The company has demonstrated that this first-in-class 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 implications of this trial expansion are substantial for both the oncology field and patients facing ovarian clear cell cancer. By doubling the patient enrollment, researchers will gather more robust data on the safety and efficacy of this combination therapy. The collaboration between an academic research institution like MD Anderson, a pharmaceutical manufacturer like GSK, and a biotechnology company like LIXTE represents a model of partnership that could accelerate drug development.

For the oncology community, this expansion signals growing interest in novel approaches to treating resistant cancers. Ovarian clear cell carcinoma represents a significant clinical challenge, and successful results from this trial could establish a new treatment paradigm for this and potentially other cancer types. The combination of LB-100 with Dostarlimab represents an innovative approach that targets both the tumor microenvironment and immune response, potentially overcoming resistance mechanisms that limit current therapies.
The broader impact extends to cancer drug development as a whole, as successful validation of the activation lethality approach could open new avenues for treating various malignancies. As clinical trials progress, the medical community will be watching closely for data that could transform treatment options for patients with limited alternatives. The expansion to Northwestern University also demonstrates how academic medical centers collaborate to advance clinical research and potentially bring new therapies to patients more efficiently.
