Ness Ziona, Israel | July 21, 2021 09:00 AM Eastern Daylight Time

Cell therapy company KadimastemLtd (TASE:KDST) has received its patent approval from the Japanese Patent Office for IsletRx, the company's innovative treatment for diabetes.

IsletRx comprises an expanded population of clinical grade pancreatic islet-like cluster (ILCs) cells, derived from human stem cells, that have the ability to secrete insulin when blood sugar is low and glucagon, a hormone secreted to prevent hypoglycemia, when blood sugar levels drop in response to varying sugar levels (glucose) in the blood. This particular function of IsletRX is similar to a "healthy" pancreas and functions to treat insulin-dependent diabetes, such as Type 1 diabetes also known as juvenile diabetes.

The patent announced today protects Kadimastem's cell selection and enrichment technology, that enables it to identify and fortify the best cells in the expanded population. The patent also covers the use of the company's special production process, where it can remove cells that are not necessary or may impair the efficiency of the transplanted cells. These capabilities are important in achieving the maximum therapeutic effect for potential future insulin-dependent diabetic patients.

In addition, this method of production and cell selection enables the ILCs to be transplanted using a variety of platforms, including very small devices that are more suitable and more convenient for patients.

Kadimastem CEO Asaf Shilonisaid, "Receiving the patent in Japan further strengthens our intellectual property position. The market, in Southeast Asia in general, and the Japanese market, are large and important for the company's future products. Registering the patent in Japan gives Kadimastem a much-welcomed priority status in this territory. We look forward to further developing business collaborations with key players in the pharmaceutical industry in Japan, both for our diabetes and ALS products."

The Japanese market is one of the most significant markets for stem cell-derived cell therapies. In Japan, 7.9% of the population is diabetic and there are more than 2.7 million insulin-dependent diabetic patients. Treatment of these patients is currently estimated at $ 29 billion.

Japan has strategic importance in the field of stem cell therapy, as it is one of the world's most prominent countries in promoting innovation and products in the field of cell therapy. In November 2014, the Japanese Parliament approved a special lawto facilitate clinical trials in the field of cellular medicine, with the aim of expediting approvals of intracellular therapies and quickly bringing them to market.
