Pluristem Therapeutics to Expand Testing of PLX Cells for the Treatment of Radiation Exposure


HAIFA, Israel, April 6, 2011 (GLOBE NEWSWIRE) -- Pluristem Therapeutics, Inc. (Nasdaq:PSTI) (TASE:PLTR) announced today that it has signed a collaborative agreement with the Hadassah University Medical Center to continue previously conducted animal study that indicates PLX cells are potentially effective in the treatment of radiation sickness.

Pluristem's preliminary study indicated that the administration of PLX cells following radiation exposure resulted in a significant improvement in the repopulation of cells of the haematopoietic system within the animal's bone marrow.

"We are excited to form a collaboration with Hadassah University Medical Center to further test the ability of our PLX cells to effectively treat radiation sickness," said Zami Aberman, Chairman, President and CEO of Pluristem. "The data collected from our initial study holds great promise for both our company and the medical industry and we look forward to validating our research and moving ahead with the next stage of testing for this important indication."

The initial study conducted by Pluristem exposed NOD/SCID mice to a sub-lethal dose of radiation (350) and then injected them with PLX cells. Approximately five weeks after the injection of the cells, a significant recovery of the animal's hematopoietic stem cells (HSCs), which give rise to all the blood cell types, including the cells of the immune system, was noted.

Additionally, Pluristem has found its PLX cells to be cytoprotective, which the company believes play a role in protecting bone marrow cells from the adverse effects of radiation exposure. "Exposure to high doses of ionizing radiation may be fatal, with no adequate efficient treatment, except for bone marrow transplantation in severe cases, which is a hazardous treatment by itself and in most cases is not easily available. Therefore, the convincing initial data from Pluristem's trial, using PLX cells to alleviate radiation damages, convinced us to move ahead with additional testing," said Prof. Raphael Gorodetsky, the Head of Laboratory of Biotechnology and Radiobiology at Hadassah University Medical Center. "We are excited to use our experience in both radiobiology and stem cells research to partner with Pluristem on this important study and we look forward to taking the steps with them towards commercializing this treatment."

About Pluristem Therapeutics

Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PLTR) is a leading developer of placenta-based cell therapies. The company's patented PLX (PLacental eXpanded) cells drug delivery platform releases a cocktail of therapeutic proteins in response to a variety of local and systemic inflammatory diseases. PLX cells are grown using the company's proprietary 3D micro-environmental technology and are an off-the-shelf product that requires no tissue matching or immune-suppression treatment prior to administration. The PLX-PAD comprehensive clinical development plan has been recognized by both the EMA and FDA, targeting a sub-population of 20 million patients in the Peripheral Artery Disease (PAD) market.

Data from two Phase I clinical trials indicate that Pluristem's first PLX product, PLX-PAD, is safe and potentially effective for the treatment of end stage PAD. Pluristem's pre-clinical animal models have demonstrated PLX cells are also potentially effective in nerve pain and muscle damage when administered locally and in inflammatory bowel disease, MS and stroke when administered systemically.

Pluristem has a strong patent portfolio, company-owned GMP certified manufacturing and research facilities and strategic relationships with major research institutions.
