First Patient Dosed with LIXTE’s LB-100 in New Clinical Trial to Treat Colorectal Cancer, Collaborating with NKI, Supported by Major Pharma Company

PASADENA, Calif., Aug. 26, 2024 (GLOBE NEWSWIRE) — LIXTE Biotechnology Holdings, Inc. (Nasdaq: LIXT and LIXTW) (“LIXTE” or the “Company”), today announced the dosing of the first patient in a new clinical trial in collaboration with the Netherlands Cancer Institute (NKI) and supported by F. Hoffmann-La Roche Ltd. (“Roche”) for treatment of unresponsive (MSI Low) metastatic colorectal cancer.

As part of the clinical trial (NCT06012734, clinicaltrials.gov), LIXTE is providing its lead compound, LB-100, and Roche is providing atezolizumab (Tecentriq ^®, a PDL1 inhibitor) through the imCORE Network, a global academic-industry partnership that aims to accelerate cancer immunotherapy research through institution-sponsored studies.

“Our objective with this trial is to bring immunotherapy as an effective treatment option to approximately 85 percent of all colorectal cancer patients, who thus far have not been responsive to traditional protocols,” said Neeltje Steeghs, M.D., Ph.D., medical oncologist at NKI.

Bas van der Baan, LIXTE’s Chief Executive Officer, said, “We are pleased to begin this important trial, which is being funded by Roche. This is the second recent clinical trial combining LB-100 with immunotherapy that is funded by a major pharmaceutical company, following the start of a clinical trial earlier this year with GSK for treatment of clear cell ovarian cancer.”
