TORONTO, ON / ACCESSWIRE / August 28, 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, radiation and or drug-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 significant enhancement of Cisplatin efficacy in chemotherapy resistant Non-Small Cell Lung Cancer ("NSCLC") in a preclinical animal model.

Theralase? recently press released its latest research, using the 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.

In further experimentation, mice were treated with Cisplatin (currently one of the most prescribed chemotherapy drugs for lung cancer) in a control group versus Cisplatin combined with Rutherrin? in an active group.

The mice treated with Cisplatin and Rutherrin? demonstrated a significantly higher (p<0.001) enhancement of cisplatin efficacy and a significantly higher (p < 0.001) increase in overall mouse survival. This survival is analogous to a 1 year overall survival in humans and is significant due to the aggressiveness of the LLCI orthotopic model.

As shown in Figure 1, the Kaplan-Meier Curve represents animal survival versus time in days. As can be seen, the combination of Cisplatin with Rutherrin? produced a highly significant increase in overall survival of mice treated versus those who were untreated or treated with Cisplatin only.

Theralase? believes that this preclinical data could be even further improved with the addition of radiation or Metformin to activate Rutherrin?, while resident in NSCLC cells.

Dr. Arkady Mandel, M.D., Ph.D., D.Sc., Chief Scientific Officer of Theralase? stated, "Cisplatin-based therapy is one of the most important and highly prescribed chemotherapy treatments for cancer; however, it's efficacy is severely limited by chemotherapy drug resistance, as over time its efficacy decreases. Therefore, it is of significant clinical importance to develop effective synergistic agents to aid in Cisplatin's efficacy. In the latest preclinical study, we have demonstrated the value of using Rutherrin?, as a synergistic agent. The combination of Rutherrin? and Cisplatin exhibited a significant synergistic anti-cancer efficacy and demonstrated significantly longer animal survival (p<0.001). Upon clinical development and commercialization, this preclinical data is very important to the clinical community in the treatment of their lung cancer patients, as it demonstrates how their patients, who do develop chemotherapy resistance, can be treated more effectively with a combination drug therapy, such as Cisplatin and Rutherrin?. These results also suggest an exciting new direction for Theralase? in future drug development to help overcome chemoresistance, which is one of the major clinical challenges in cancer therapy".

Roger DuMoulin-White, B.E.Sc., P.Eng., Pro.Dir., President and Chief Executive Officer of Theralase? stated, "This latest research is extremely important to the clinical community, as pending regulatory approval, it provides an opportunity on how to treat their patient base, who have developed chemotherapeutic resistance to Cisplatin. 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 in 2025. 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 Cisplatin:

Many chemotherapeutic drugs have been explored and developed for clinical studies. Cisplatin is one of the most potent anti-cancer agents ever developed. It provides clinical effectiveness against a wide spectrum of solid cancers and has been in clinical use for many years; however, many kinds of cancer cells are immune to it or quickly become chemoresistant to it.

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 to be about 26.6%. Lung cancer is histologically classified into two main types: Small Cell Lung Cancer ("SCLC"), which accounts for approximately 15% of the patients diagnosed with lung cancer and Non-Small Cell Lung Cancer ("NSCLC"), which accounts for approximately 85%.
