"The patent award further bolsters LIXTE’s existing intellectual property portfolio and underscores the Company’s commitment to pioneering research and delivering innovative solutions to patients battling cancer," said Bas van der Baan, LIXTE’s Chief Executive Officer.
LIXTE is developing its first-in-class lead clinical PP2A inhibitor, LB-100, as a potentiator of cancer immunotherapy. The Company is testing LB-100 in combination with immunotherapies in clinical trials at the Netherlands Cancer Institute (NKI) in Amsterdam and at The University of Texas MD Anderson Cancer Center in Houston.
At NKI, LIXTE is providing LB-100, and F. Hoffmann-La Roche Ltd. ("Roche") is providing atezolizumab (Tecentriq, a PD-L1 inhibitor) through the imCORE Network as part of a new clinical trial in immune therapy for unresponsive (MSI Low) metastatic colon cancer. The imCORE Network is an academic-industry collaboration that aims to accelerate cancer immunotherapy research through institution-sponsored studies
A second trial underway at MD Anderson is testing the combination of LB-100 and GSK’s dostarlimab-gxly for the treatment of ovarian clear cell carcinoma (OCCC).
The new patent award follows the signing of an exclusive patent license agreement earlier this year between LIXTE and the National Institute of Neurological Disorders and Stroke (NINDS) and National Cancer Institute (NCI), each a component of the National Institute of Health (NIH). The agreement provides LIXTE with an opportunity to explore and develop novel combination therapies that can potentially transform the landscape of cancer treatment.
