LIXTE Biotechnology Holdings has expanded 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.
This expansion represents a significant step in addressing ovarian clear cell carcinoma, an aggressive subtype of ovarian cancer that often shows resistance to conventional chemotherapy. The company expects data from the initial cohort to be presented in the first half of 2026, providing crucial insights into the combination therapy's efficacy and safety profile. The trial's growth from one to two major cancer research institutions increases both patient access and the study's scientific rigor through broader geographic and demographic representation.
LIXTE's lead compound, LB-100, represents a pioneering effort in an entirely new field of cancer biology called activation lethality, which advances a new treatment paradigm. The compound is a first-in-class PP2A inhibitor that has demonstrated tolerability 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 importance of this trial expansion lies in its potential to address a significant unmet medical need in oncology. Ovarian clear cell cancer accounts for approximately 5-25% of ovarian cancers in Western countries and is associated with poorer prognosis compared to other epithelial ovarian cancers. The combination of LB-100 with GSK's Dostarlimab represents a novel approach that could overcome treatment resistance mechanisms common in this cancer subtype.

For the pharmaceutical industry, this collaboration demonstrates how smaller biotechnology companies can partner with major cancer centers and large pharmaceutical manufacturers to accelerate clinical development. The expansion to Northwestern University's cancer center creates additional validation points for the therapeutic approach while potentially speeding patient recruitment. The trial's progress may influence future research directions in combination therapies targeting both tumor cells and the immune system simultaneously.
Patients and healthcare providers should note that this expansion increases access to experimental treatment options for ovarian clear cell cancer patients who may have exhausted standard therapies. The doubled enrollment target improves statistical power for detecting meaningful clinical benefits while maintaining rigorous safety monitoring. As proof-of-concept clinical trials continue for both ovarian clear cell carcinoma and metastatic colon cancer, the medical community awaits data that could validate this new approach to cancer treatment.
