The FDA's Office of Counterterrorism and Emerging Threats, Medical Countermeasures Initiative, invited Pluristem to present at this symposium. William R. Prather RPh, MD, Pluristem's Senior Vice President Corporate Development, will present Pluristem's patented PLX (PLacental eXpanded) cell technology and its potential use in the treatment of the complications arising from the acute radiation syndrome (ARS). The data presented by Dr. Prather include preliminary preclinical information on the radio-mitigating activity of intramuscularly administered PLX-RAD cells generated in collaboration with Professor Raphael Gorodetsky and his team at the Biotechnology and Radiobiology Laboratory at the Sharett Institute of Oncology at Hadassah Medical Center, Hadassit,Hadassah Medical Organization (HMO), Jerusalem, the National Institute of Allergy and Infectious Diseases (NIAID), Bethesda, MD, and the Berlin Bradenburg Center for Regenerative Therapies (BCRT), Charite University, Berlin.  

Zami Aberman, Pluristem's Chairman and CEO, stated, "We are proud to be invited to present data on the use of our PLX cells to mitigate the harmful effects sustained from acute radiation injury. This presentation is a supplement to the work currently being performed by the National Institute of Allergy and Infectious Diseases (NIAID), a part of the U.S. National Institutes of Health (NIH), to evaluate our PLX cells in animal models of ARS."

 About Acute Radiation Syndrome (ARS)

ARS represents a constellation of signs and symptoms that occur between several minutes and several weeks after exposure to high doses of ionizing radiation and affecting multiple organs such as the hematological and gastrointestinal systems. The hematological syndrome follows radiation damage to the bone marrow and is characterized by severe decreases in red blood cells, white blood cells and platelets that predispose afflicted individuals to infection, bleeding and potential death.

The gastrointestinal syndrome follows radiation damage to the gastrointestinal tract that can result in diarrhea, dehydration, electrolyte imbalance and infection that can lead to death.
