LIXTW Lixte Biotechnology Holdings Inc

LIXTE Biotechnology Holdings, Inc. (“LIXTE” or the “Company”) (Nasdaq: LIXT and LIXTW), a clinical-stage pharmaceutical company developing a new class of cancer therapy to enhance chemotherapy and immunotherapy, today provided an update on the Company’s recent activities.

“We are encouraged by the growing interest shown by major pharmaceutical companies in our proprietary compound, LB-100, as demonstrated by their support in clinical trial collaborations,” said Bas van der Baan, LIXTE’s President and Chief Executive Officer.

“Highlighting the Company’s recent progress is our new agreement with The Netherlands Cancer Institute, supported by F. Hoffmann- La Roche Ltd. (“Roche”), which is funding the clinical trial in metastatic colorectal cancer and providing atezolizumab (Tecentriq®, a PD-L1 inhibitor) through the imCORE network, an academic industry collaboration that aims at accelerating cancer immunotherapy research through institution sponsored studies. Already underway is a proof-of-concept trial, funded by GSK, of LB-100 plus GSK’s dostarlimab-gxly in ovarian clear cell cancer.

“We are seeing encouraging results in the first phase of our clinical trial to determine appropriate dosing and toxicity for treating advanced soft tissue sarcomas with a combination of LB-100 and standard-of-care chemotherapy and expect to see the data from this first phase early in 2025. We are exploring alternative sites, including international locations, for our small cell lung cancer trial, following termination of that clinical trial at City of Hope due to limited patient accrual,” Mr. van der Baan added.

Recent Company Highlights:

• Collaboration with the Netherlands Cancer Institute, supported by Roche, to conduct a new clinical trial (NCT06012734 in clinicaltrials.gov) in immune therapy for unresponsive (MSI Low) metastatic colorectal cancer. LIXTE is providing its lead compound, LB-100, and Roche will provide atezolizumab (Tecentriq®,a PD-L1 inhibitor). The clinical trial will test recent findings that indicate that LB-100 increases recognition of colorectal cancer cells by the immune system.
• Jan Schellens, M.D., Ph.D., joined LIXTE as Chief Medical Officer effective August 1, 2024. Dr. Schellens brings to the Company more than 25 years of clinical experience as a medical oncologist, pharmacologist and clinical pharmacologist, including more than two decades developing and bringing new drugs to market. Co-author of more 900 publications in peer-reviewed scientific journals, Dr. Schellens has held leadership positions at the Netherlands Cancer Institute in Amsterdam and the Dr. Daniel den Hoed Clinic-Erasmus University in Rotterdam. He was professor of clinical pharmacology at Utrecht University in the Netherlands, where he earned his M.D. degree, and he served as a board member and Chief Medical Officer of Byondis B.V. in Nijmegen, Netherlands. Dr. Schellens also earned a Ph.D. degree in Pharmaceutical Sciences from Leiden University in Leiden, Netherlands.
• New pre-clinical data in the journal EMBO Reports shows that LIXTE’s lead compound, LB-100, can turn immunologically “cold” tumors “hot,” potentially enhancing the benefit of immunotherapy. In a paper titled, “The Phosphatase Inhibitor LB-100 Creates Neoantigens in Colon Cancer Cells through Perturbation of mRNA Splicing,” the article reported that LIXTE’s collaborators from the Netherlands Cancer Institute have demonstrated that treatment of cancer cells with LB-100 disrupts the normal processing of the mRNA that encodes proteins, thereby generating neo-antigens that are presented to the host immune system. This new mechanism adds to several previous discoveries showing that LB-100 sensitizes cancer cells to immune checkpoint blockade.
• LIXTE will present at two upcoming investor conferences: the 2004 Summit Summer 2024 Virtual Conference, August 20, 2024, and the H.C. Wainwright 26th Annual Global Investor Conference, September 9-11, 2024. Both conferences will be virtual presentations.
