12:50 EDTPSTIPluristem says NIH study of PLX-R18 statistically significant
Pluristem Therapeutics announced the results of a recently completed trial conducted by the U.S. National Institutes of Health to evaluate PLX-R18 cells to treat bone marrow damaged by exposure to high levels of radiation, such as can occur after a nuclear disaster. Injection of PLX-R18 cells into muscle, as compared to a placebo, resulted in a statistically significant improvement in the recovery of white blood cell, red blood cell, and platelet levels in animals exposed to high levels of radiation, the company said. It added, "The data also suggested that the treatment may potentially be able to shorten time to recovery."

05:17 EDTPSTIPluristem Therapeutics reports 'significant' findings in NIH trial of PLX-R18
Pluristem Therapeutics announced the positive results of a recently completed trial conducted by the U.S. National Institutes of Health, or NIH, to evaluate PLX-R18 cells to treat bone marrow damaged by exposure to high levels of radiation, such as can occur after a nuclear disaster. Injection of PLX-R18 cells into muscle, as compared to a placebo, resulted in a statistically significant improvement in the recovery of white blood cell, red blood cell, and platelet levels in animals exposed to high levels of radiation. The data also suggested that the treatment may potentially be able to shorten time to recovery. High levels of radiation can destroy the body's ability to produce these three blood lineages, and rapidly regaining that capacity is a key factor in surviving the hematologic component of acute radiation syndrome, or ARS, a condition caused by high-dose irradiation that can involve severe, sometimes lethal damage to the bone marrow as well as other physiologic systems and organs. The objective of this latest trial was to investigate the mechanism of action behind the significant improvement in survival in irradiated mice treated with PLX-R18 that was demonstrated in the NIH's first efficacy study. The results of the current study indicate that intramuscular administration exerts a systemic healing effect on bone marrow, lending further support to the concept that Pluristem's cells work systemically via secretion of therapeutic proteins, although the cells themselves remain in the muscle into which they were initially injected. While additional animal trials are needed prior to FDA approval of PLX-R18 for use in ARS, no human trials would be required because product development is conducted under the FDA's Animal Rule.
