LIXTE Biotechnology (Nasdaq: LIXT) has announced a new pre-clinical study in collaboration with Netherlands Cancer Institute (NKI) to test if their compound LB-100 can eliminate pre-cancerous 'initiated' cells that carry mutations found in cancer cells.
The study builds upon LIXTE's ongoing clinical trials in ovarian and colorectal cancer. Recent data from their NKI collaboration shows LB-100 activates oncogenic signaling, which is detrimental to cancer cells. The new animal model study will specifically investigate if cells harboring mutant RAS oncogene can be eliminated with LB-100.
If successful, LB-100 could potentially reduce cancer risk in aging populations by eliminating initiated cells. The research will be led by Dr. René Bernards, Senior Staff Scientist at NKI and LIXTE board member. Phase 1 trials have already demonstrated LB-100's patient tolerance with minimal toxicity.
LIXTE Biotechnology (LIXT) has announced significant progress in its cancer treatment development programs. The company has initiated two new clinical trials for its lead compound LB-100: a Phase 1b/2 trial combining LB-100 with GSK's dostarlimab-gxly for ovarian clear cell carcinoma, and a trial with the Netherlands Cancer Institute and Roche for unresponsive metastatic colorectal cancer.
Key developments include successful patient dosing in both trials, receipt of a USPTO Notice of Allowance for combining LB-100 with cancer immunotherapies, and completion of a $1,050,000 registered direct offering. Two breakthrough studies were published: one in Cancer Discovery showing LB-100's ability to force cancer cells to relinquish malignant properties, and another in EMBO demonstrating how LB-100 makes cancer cells more vulnerable to immunotherapy.
LIXTE Biotechnology Holdings (Nasdaq: LIXT) announced new pre-clinical data published in BioXriv and International Journal of Pharmaceutics regarding their lead clinical compound LB-100. The research reveals how LB-100 converts into its active form, endothall, a protein phosphatase inhibitor effective in cancer treatment with immunotherapy.
Scientists at the Netherlands Cancer Institute discovered an enzyme that mediates LB-100's conversion into endothall, potentially serving as a biomarker to identify patients most likely to respond to treatment. Additionally, research by BioPharmaWorks showed that while LB-100 can spontaneously convert to endothall through hydrolysis under physiological conditions, this process is slow, with the newly discovered enzymatic conversion accelerating the activation inside cells.
The company is currently conducting clinical trials of LB-100 for ovarian cancer and colorectal cancer treatment. These findings will help optimize patient selection for future clinical trials.
LIXTE Biotechnology Holdings, Inc. (Nasdaq: LIXT) has expanded its clinical trial for ovarian clear cell cancer by adding the Robert H. Lurie Comprehensive Cancer Center of Northwestern University as a second site. The trial combines LIXTE's proprietary compound LB-100 with GSK's immunotherapy Dostarlimab.
Dr. Emily M. Hinchcliff will lead the trial at Lurie Cancer Center, where patient recruitment is underway and the first patient has already been dosed. This expansion follows the trial's initial launch in January 2024 at The University of Texas MD Anderson Cancer Center under lead investigator Dr. Amir Jazaeri.
The clinical trial aims to determine if adding LB-100 to Dostarlimab enhances immunotherapy effectiveness in treating ovarian clear cell carcinoma, which represents a disease with high unmet medical needs.
