Lixte Biotechnology and City of Hope Enroll First Patient in Phase 1b Trial of Lead Compound LB-100 for Treatment of Small Cell Lung Cancer
On June 2, 2021, Lixte Biotechnology Holdings announced the enrollment of the first patient in a Phase 1b clinical trial for LB-100, a PP2A inhibitor, in combination with chemotherapy for extensive stage small cell lung cancer (ED-SCLC). The trial, conducted at City of Hope, aims to assess the therapeutic benefit of LB-100 alongside carboplatin, etoposide, and atezolizumab. Preclinical data suggests that LB-100 enhances chemotherapy effectiveness in animal models. Approximately 30,000 new cases of small cell lung cancer are diagnosed annually in the U.S., highlighting the urgent need for effective treatments.
- Enrollment of the first patient in Phase 1b clinical trial for LB-100, indicating progress in research.
- Preclinical data shows LB-100 enhances chemotherapy effectiveness, suggesting potential for improved patient outcomes.
- The trial focuses on a type of cancer with a median survival of only nine months, indicating the urgency but also the challenges in achieving meaningful results.
- Extensive preclinical data shows LB-100 increases the effectiveness of chemotherapy in animal models
- Due to the aggressive progression of small cell lung cancer, it is possible that therapeutic benefit in patients may be seen in this early-stage clinical trial
EAST SETAUKET, NY, June 02, 2021 (GLOBE NEWSWIRE) -- Lixte Biotechnology Holdings, Inc. (Nasdaq: LIXT), a clinical-stage drug discovery company developing pharmacologically active drugs for use in cancer treatment, today announced the enrollment of the first patient in a Phase 1b clinical trial with City of Hope, a world-renowned independent cancer research and treatment center. The trial will assess the combination of Lixte’s first-in-class protein phosphatase 2A (PP2A) inhibitor LB-100 with a standard regimen for previously untreated, extensive stage-disease small cell lung cancer (ED-SCLC) (NCT04560972).
John S. Kovach, M.D., Lixte founder and chief executive officer, said, “In collaboration with City of Hope, we are eager to pursue our well-grounded rationale for adding LB-100 to a standard ED-SCLC regimen of carboplatin and etoposide chemotherapy plus atezolizumab to enhance effectiveness. In preclinical studies, the malignant cells of this uniformly fatal cancer are genetically sensitive to PP2A inhibition by a process termed synthetic lethality and the effectiveness of the standard regimen is enhanced by LB-100.
“Small cell lung cancer comprises approximately
Ravi Salgia, M.D., Ph.D., City of Hope’s Arthur & Rosalie Kaplan Chair in Medical Oncology, said, “We are hopeful that this trial testing a potentially more effective therapeutic combination could provide another treatment option for small cell lung cancer patients. It is a disease that is currently difficult to treat, particularly after a patient has relapsed, so more therapeutic options are needed.”
About the Study
In the Phase 1b trial of LB-100 for the treatment of ED-SCLC, Lixte’s lead compound will be given in combination with carboplatin, etoposide and atezolizumab, an FDA approved but marginally effective regimen, in previously untreated ED-SCLC. The dose of LB-100 will be escalated with fixed doses of the 3-drug regimen to reach a recommended Phase 2 dose (RP2D). Patient entry will then be expanded so that a total of 12 patients will be evaluable at the RP2D to confirm its safety and to look for objective evidence of potential therapeutic activity as assessed by objective response rate, duration of overall response, progression-free-survival and overall survival. The study is open at City of Hope in Duarte, California.

About Lixte Biotechnology Holdings, Inc.
Lixte Biotechnology Holdings, Inc. (Nasdaq: LIXT), is a clinical-stage pharmaceutical company dedicated to discovering drugs for more effective treatments for many forms of cancer and other serious common diseases. A major driver of cancer is defects in the switches that turn the biochemical pathways in cells on and off. Most cancer research over the past 30 years has focused on the “on” switches because the “off” switches, especially the master “off” switch protein phosphatase (PP2A), were believed to cause intolerable toxicity in patients. Lixte has achieved a breakthrough with its novel, first-in-class lead compound, PP2A inhibitor LB-100, by demonstrating that it is readily tolerated in cancer patients at doses associated with anti-cancer activity. This innovative approach encourages cancer cells, damaged by chemo or other cancer therapies, to continue to replicate before repairing the damage, leading to the more efficient death and elimination of those cells from the body. Lixte has partnered with top medical institutions and leading academic research centers to advance the clinical development of its compounds. The LB-100 compound, of which there are no competitors known to Lixte, is being tested in three clinical cancer treatment studies with others in planning. www.lixte.com
