Pluristem Expands its Reach in the Treatment of Impaired Hematopoietic Systems with a European Patent Covering PLX-R18 in Chemotherapy, ARS, Genetic Disorders and Autoimmune Diseases

Pluristem Therapeutics Inc. (PSTI) (PSTI), a leading developer of placenta-based cell therapy products, announced today that the European Patent Office has issued the company a patent titled, “Methods for Treating Radiation or Chemical Injury” for its PLX-R18 cell therapy.

Pluristem currently holds several patents worldwide to cover placental 3D-expanded cells in the treatment of impaired hematopoietic systems when a bone marrow, cord blood, or peripheral blood transplant takes place. This important patent expands Pluristem’s IP assets to include a new set of indications related to the bone marrow’s inability to produce blood cells, such as acute radiation syndrome (ARS), autoimmune diseases such as aplastic anemia, genetic disorders, chemotherapy, radiation therapy, and side effects from other treatments. Pluristem currently holds over 115 issued patents and 100 pending patent applications worldwide.

“PLX-R18 is covered by several patents in key markets for the treatment of bone marrow failure following a transplant of hematopoietic stem cells, or for the support of such a transplant. What makes this a key patent for our IP assets is that it addresses the treatment of a much broader range of medical conditions in which bone marrow is damaged and the patient has not received a transplant,” stated Yaky Yanay, Co-CEO and President of Pluristem. “PLX-R18 cells have shown the ability to trigger regeneration of the hematopoietic system, thereby supporting the recovery and production of white blood cells, red blood cells and platelets.  With its capabilities, we believe that PLX-R18 has the potential to treat a broad range of hematologic indications, which together constitute a substantial global market.”

About PLX-R18

PLX-R18 is Pluristem’s second cell therapy product in development. It is designed to treat bone marrow that is unable to produce enough blood cells due to a variety of causes, including acute radiation syndrome (ARS), certain cancers or cancer treatments, or immune-mediated bone marrow failure. PLX-R18’s first animal studies to prove their activity in ARS, as reflected in the new patent, were performed in collaboration with Prof. Gorodetsky at Hadassah Medical Center. Further preclinical data from trials conducted by the U.S. National Institutes of Health, Hadassah, the Charite in Berlin and other prominent research institutions have shown that PLX-R18 cells secrete a range of specific proteins that trigger the regeneration of bone marrow hematopoietic cells, thereby supporting the recovery of blood cell production. Pluristem is currently enrolling patients in a U.S. Phase I trial of PLX-R18 in incomplete bone marrow recovery following hematopoietic cell transplantation (HCT) and is preparing for a pivotal trial in ARS.
