HAIFA, Israel, Nov. 7, 2012 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PLTR), a leading developer of placenta-based cell therapies, announced today the Company has successfully completed the integration and testing of its new scaled-up formulation and manufacturing process to produce high-yield quantities of its Placental eXpanded (PLX) cells for clinical trials and potential commercial use. The increased automation and larger scale process allows the company to produce billions of live cells simultaneously.

As part of its manufacturing process, Pluristem has optimized growth conditions to maximize yields with lower costs. The company has minimized open manipulation steps in order to improve the aseptic quality and safety of the product. Critical steps have been automated including the process of harvesting and purification; the integration of closed system washing and concentration steps, and the product's final packaging has been changed to an aseptically automated vial system. In the past 15 months, Pluristem has invested resources and efforts to develop technologies resulting in an efficient, cutting edge production line. All of the integrated changes have been tested and will be integrated into Pluristem's new production site in Israel.

Pluristem recently announced it is in the final steps of building out its new manufacturing facility, which will have the capacity to produce commercial grade PLX cells. Once completed, and following regulators' approval, the new facility would have the capacity to produce PLX cells for the treatment of over 150,000 patients annually estimated by Pluristem at $1 billion in production value.

"This new large scale manufacturing process allows us to run numerous clinical trials simultaneously around the globe, and also prepares us for potential commercial availability," stated Zami Aberman, Chairman and CEO of Pluristem. "Our progress with both our manufacturing process and facility are well on track."

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 are a drug delivery platform that releases a cocktail of therapeutic proteins in response to a host of local and systemic inflammatory and ischemic 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 prior to administration. Pluristem is focusing on the development of PLX cells administered locally to potentially treat systemic diseases and potentially obviating the need to use the intravenous route.

Data from two phase I studies indicate that Pluristem's first PLX product candidate, PLX-PAD, is safe and potentially effective for the treatment of end stage peripheral artery disease when given locally. Additionally, Pluristem is developing PLX-PAD for cardiac ischemia; PLX-BMP for Acute Radiation Exposure, Bone Marrow Transplant Failure and Chemotherapy induced Bone Marrow Aplasia, PLX-ORTHO for orthopedic indications and PLX-PAH for Pulmonary Hypertension in collaboration with United Therapeutics. Pluristem's pre-clinical animal models have demonstrated PLX cells are also potentially effective in other inflammatory/ischemic indications, including diastolic heart failure, inflammatory bowel disease, neuropathic pain and pulmonary fibrosis.

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

Safe Harbor Statement

This press release contains forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 and federal securities laws. For example, when we discuss how the increased automation and larger scale process allows us to produce billions of live cells simultaneously, when we discuss the integration of changes into our new production site, when we discuss our new manufacturing facility, its planned capacity for production of PLX cells and estimated production value assuming the PLX cells product candidates are successfully developed and approved by the regulators, when we discuss that the new manufacturing process allows us to run numerous clinical trials simultaneously around the globe, and also prepares us for potential commercial availability, when we discuss that PLX cells are safe and can potentially treat PAD or that PLX cells are also potentially effective in other inflammatory/ischemic indications, we are using forward-looking statements. These forward-looking statements are based on the current expectations of the management of Pluristem only, and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements.
