• Publishing of Findings in Recent Pre-Clinical Study for LIXTE’s Proprietary Compound, LB-100, in New Field of Cancer Biology, “Activation Lethality”
• Presentation at MedInvest Biotech and Pharma Investor Conference
• Co-Sponsorship/Presentation of Workshop at Harvard University’s Dana Farber Cancer Institute

PASADENA, CA, May 20, 2024 (GLOBE NEWSWIRE) -- 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, including notable pre-clinical developments.

“LIXTE continues to make progress with its proprietary compound, LB-100, in ongoing clinical trials for lung, ovarian and sarcoma cancers,” said Bas van der Baan, LIXTE’s President and Chief Executive Officer. “We also are pleased with the findings of recent pre-clinical data with LB-100 in an entirely new field of cancer biology -- activation lethality -- that we believe has outstanding potential in advancing new treatment options.”

Recent Company highlights include:

• Pre-clinical studies in a new field of cancer biology -- activation lethality -- have shown that LB-100 can force cancer cells to give up their cancer-causing properties. The findings open a potentially new treatment strategy in addition to LIXTE’s current three ongoing clinical trials. René Bernards, Ph.D., a leader in the field of molecular carcinogenesis and Senior Staff Scientist at the Netherlands Cancer Institute, presented the new pre-clinical data at the Joint Conference of European and American Associations for Cancer Research in Dublin, Ireland. The paper, “Paradoxical Activation of Oncogenic Signaling as a Cancer Treatment Strategy,” was posted in the online medical journal Cancer Discovery on April 30, 2024. Dr. Bernards is a member of LIXTE’s Board of Directors.
• Bas van der Baan, LIXTE’s President and Chief Executive Officer, presented at the MedInvest Biotech and Pharma Investor Conference on April 3, 2024 in New York City. The two-day event featured presentations from more than 40 companies, developing and commercializing technologies across a broad spectrum of indications, including oncology. The conference also featured talks from key industry opinion leaders, investor panel discussions, and conversations with the National Cancer Institute on patenting, facilitating collaborations, licensing and technology analysis and marketing. 
• LIXTE co-sponsored an international scientific workshop on “Therapeutic Over-Activation in Cancer” at Harvard University’s Dana Farber Cancer Institute in Boston, Massachusetts on May 9 and 10, 2024. The workshop brought together leading experts from the pharmaceutical industry and academia who discussed a radically different approach to cancer therapy that is being spearheaded by LIXTE’s outsourced research team at the Netherlands Cancer Institute.

LIXTE has clinical trials underway at the University of Texas MD Anderson Cancer (ovarian clear cell carcinoma); City of Hope Cancer Center and the Sarah Cannon Research Institute (small cell lung cancer); and the Spanish Sarcoma Group (advanced soft tissue sarcoma). In February 2024, LIXTE signed an exclusive patent license agreement with the National Institute of Neurological Disorders and Stroke (NINDS) and the National Cancer Institute (NCI), each an institute or center of the National Institute of Health (NIH).
