Patent to Destroy Cancer Cells with X-Ray Activated Photo Dy
Member Login Image Theralase Granted United States Patent to Destroy Cancer Cells with X-Ray Activated Photo Dynamic Compounds Toronto, Ontario March 4, 2019 Theralase Technologies Inc. (Theralase or the Company) (TSXV: TLT) (OTCQB: TLTFF), a clinical stage pharmaceutical company dedicated to the research and development of light activated Photo Dynamic Compounds (PDCs) and their associated drug formulations intended to safely and effectively destroy various cancers, announced today that it has been granted allowance for a United States patent to issue later this year for destroying cancer cells with X-ray activated PDCs. The new patent to issue later this year is entitled, Photodynamic Compounds and Methods for Activating Them Using Ionizing Radiation and/or Other Electromagnetic Radiation for Therapy and/or Diagnostics Arkady Mandel, M.D., Ph.D., D.Sc., Chief Scientific Officer of Theralase and the lead inventor of the technology stated that, In 2019, the Company plans to commence a Phase II Non-Muscle Invasive Bladder Cancer (NMIBC) clinical study, which if successful may lead to commercialization of this technology in Canada, the United States and the European Union. On top of this clinical study, this patent opens up new possibilities with far reaching oncological treatment implications, including: targeting cancers that are difficult, if not impossible to reach with surgery or conventional laser light sources, such as Glio Blastoma Multiforme (GBM), a deadly form of brain cancer, Non-Small Cell Lung Cancer (NSCLC) or other deep tissue related cancers, such as soft tissue sarcomas. The Company is investigating evaluating Rutherrin (TLD-1433 PDC combined with transferrin) in combination with X-ray in a Phase Ib clinical study for GBM. This patent, when issued, will validate the proprietary position of the Companys Anti-Cancer Technology (ACT) for the US oncology market, demonstrating Theralases strong commitment to the development of a comprehensive intellectual property portfolio, attractive to a pharmaceutical partner. About Rutherrin On the surface of all cells, there are carrier proteins known as Transferrin Receptors (TfRs). These TfRs main role is to link with the glycoprotein Transferrin (Tf) to enable the cell to absorb iron, an essential element required for energy production and metabolism. Due to the high proliferation rate of cancer cells (which makes them so deadly to the human body), they possess a greater quantity of TfRs and hence they absorb a greater quantity of iron than normal cells. TLD-1433 is a Theralase patented ruthenium metal-based molecule. Ruthenium is a transitional VIII metal element (as is Iron and Osmium), in the periodic table, that possesses similar properties to iron. Theralase has demonstrated that TLD-1433 bonds with transferrin to produce Rutherrin and in so doing, TLD-1433 is able to be selectively transported, preferentially, and in much higher quantities to cancer cells versus normal cells through the TfR. Once inside the cancer cell, TLD-1433, when light activated, produces a violent form of oxygen, known as Reactive Oxygen Species (ROS), that is able to effectively destroy the cancer cell from the inside out. According to the Canadian patents claims, that will issue later this year, Rutherrin possesses one or all of the following characteristics:a) increased uptake by cancer cells; b) increased efficacy at wavelengths less than, equal to or longer than 600 nm; c) increased production of ROS; d) increased Photo Dynamic Therapy (PDT) effect under hypoxic or non-hypoxic conditions; e) increased Maximum Tolerated Dose (MTD); f) increased photostability; and / or g) increased shelf-life Rutherrin technology is patent pending in the United States, the European Union, Brazil, Russia, India and China. These countries account for approximately 65% of the worlds Gross Domestic Product (GDP) (2015 statistics). If patents are allowed to issue in these countries, the Rutherrin technology will be able to be fully commercialized and protected in these major medical markets. About NMIBC In 2016, an estimated 79,030 adults (60,490 men and 18,540 women) were diagnosed with bladder cancer in the United States. Among men, bladder cancer is the fourth most common cancer. It is estimated that 16,870 deaths (12,240 men and 4,630 women) from this disease will occur in 2016. Among men, bladder cancer is eighth most common cause of cancer death. About GBM There are an estimated 24,000 new cases of malignant gliomas diagnosed in the US annually, with more than 14,000 deaths. In the majority of cases, they recur following initial treatment, especially for GBM, the most common and lethal form of brain cancer. Most patients do not survive beyond 2 years, post diagnosis. About NSCLC Lung cancer is by far the leading cause of cancer death among both men and women. Out of all types of lung cancer, NSCLC accounts for 80 to 85% of cases. The American Cancer Societys estimates for lung cancer in the United States for 2018 are: About 234,030 new cases of lung cancer (121,680 in men and 112,350 in women) About 154,050 deaths from lung cancer (83,550 in men and 70,500 in women) About Theralase Technologies Inc.
