Rutherrin(R) Demonstrates Complete Response in Lung Cancer Preclinically
Theralase Technologies announced that its lead drug formulation, Rutherrin®, demonstrated a complete response in preclinical studies for Non-Small Cell Lung Cancer (NSCLC). Using a well-established Lewis Lung Cancer (LLC1) model, mice treated with x-ray activated Rutherrin® showed a significant reduction in tumor progression and increased overall survival compared to the control group treated with radiation only. Notably, one mouse achieved a complete response, becoming cancer-free. The company aims to optimize this therapy for higher success rates and expand its cancer treatment targets, which now include bladder, brain, lung, and various blood-based cancers. Pending further research and sufficient funding, Theralase plans to commence clinical studies for these cancers.
- Rutherrin® demonstrated a complete response in a preclinical NSCLC model.
- Mice treated with x-ray activated Rutherrin® showed up to a 4-fold reduction in tumor progression.
- Overall survival in treated mice increased from 26 to 35 days.
- Theralase plans to expand its cancer treatment targets to brain, lung, and blood-based cancers.
- Pending sufficient funding, clinical studies for brain, lung, and blood-based cancers will commence.
- The complete response was observed in only one mouse, indicating variability in treatment effectiveness.
- Further optimization and research are needed to achieve consistent results.
- Theralase requires sufficient capitalization and completion of GLP toxicology analysis to proceed with clinical studies.
TORONTO, ON / ACCESSWIRE / June 19, 2024 / Theralase® Technologies Inc. ("Theralase®" or the "Company") (TSXV:TLT)(OTCQB:TLTFF), a clinical stage pharmaceutical company dedicated to the research and development of light and/or radiation activated small molecules and their formulations, intended for the safe and effective destruction of various cancers, bacteria and viruses, is pleased to announce that it's lead drug formulation, Rutherrin®, has demonstrated an ability to provide a complete response in a Non-Small Cell Lung Cancer ("NSCLC") animal model.
Theralase® recently press released its latest research, using a well-established Lewis Lung Cancer ("LLC1") orthotopic model, representing NSCLC. In this model, mouse lungs are implanted with lung cancer cells, inducing these mice to develop very aggressive, fast growing and metastatic lung tumors.
The mice were treated with x-ray radiation only as a control and x-ray activated Rutherrin® as the active arm. The mice treated with x-ray activated Rutherrin® demonstrated up to a 4-fold reduced tumor progression, based on Computerized Tomography ("CT") scan assessment of tumor volumes.
As shown in Figure 1, there was a significant delay in tumor progression in mice treated with x-ray activated Rutherrin® versus radiation (x-ray) alone (p> 0.001). In fact, in mice treated with x-ray activated Rutherrin®, the tumour is notably regressing / being destroyed over time.
As an update to this research, as shown in Figure 2, the Kaplan-Meier curve representing animal survival demonstrates a significant increase in overall survival of mice treated with x-ray activated Rutherrin® versus radiation only.
These results demonstrate that animals treated with a combination of Rutherrin® and radiation therapy showed an increase in median survival from 26 to 35 days, versus radiation only. In scientific publications, mouse survival of 9 days has been equated to the equivalent of 1 year survival in humans, but more importantly, is that one animal treated with the x-ray activated Rutherrin® (which had a positive lung tumor verified by CT scan) demonstrated a complete response and is now considered cancer free.
Dr. Arkady Mandel, M.D., Ph.D., D.Sc., Chief Scientific Officer of Theralase® stated, "The latest preclinical research demonstrates the ability of x-ray activated Rutherrin® to eradicate lung cancer in an animal model. This is initial research and through optimization, Theralase® hopes to achieve a complete response in a much greater percentage of animals, but this initial data is extremely encouraging. As a result of this latest success, Theralase® has committed to bringing this technology to market through the systematic research and development of this cutting-edge clinical therapy to safely and effectively destroy various cancers in patients. As a direct result, our list of cancer targets has increased from bladder cancer, which in the late stage of clinical development, to encompass brain cancer, lung cancer and various blood-based cancers, such as: leukemia, lymphoma and multiple myeloma."
Roger DuMoulin-White, B.E.Sc., P.Eng., Pro.Dir., President and Chief Executive Officer of Theralase® stated, "This latest research symbolizes the significant progress Theralase® has made over the last few years in the research and development of world-class systemic and targeted therapies for the treatment of various hard-to- treat cancers, such as: bladder cancer, brain and lung cancer. Pending sufficient capitalization and completion of a Good Laboratory Practice ("GLP") toxicology analysis for Rutherrin®, Theralase® plans to commence clinical studies for brain cancer, lung cancer and various blood-based cancers. If proven safe and effective in humans, Theralase® hopes to change the paradigm of how patients diagnosed with cancer are treated in the future."
About Lung Cancer:
Lung cancer is the leading cause of cancer death worldwide. Most patients die of progressive metastatic disease despite aggressive local and systemic therapies. The survival rate for lung cancer depends on the type, stage and age of the patient, with the overall 5-year survival rate for all types of lung cancer about
