Pluristem Reports Status of Orphan Drug Application for Aplastic Anemia

Pluristem Reports Status of Orphan Drug Application for Aplastic Anemia

FDA Acknowledges Aplastic Anemia as Rare Disease and Requests Further Data
From the Company in Connection With Application

HAIFA, Israel, Nov. 21, 2012 (GLOBE NEWSWIRE) -- Pluristem Therapeutics, Inc.
(Nasdaq:PSTI) (TASE:PLTR), a leading developer of placenta-based cell
therapies, today announced that the U.S. Food and Drug Administration (FDA)
has updated the Company on its application to designate Pluristem's PLacental
eXpanded (PLX) cells orphan drug status in the treatment of aplastic anemia.
The FDA acknowledged that aplastic anemia is a rare disease with prevalence in
the United States of less than 200,000. This serves as confirmation that
aplastic anemia is an indication for which candidate treatments are eligible
for orphan drug status. The FDA has also requested that Pluristem provide
additional information and data for further analysis before the FDA can
determine if the PLX cells can qualify for orphan drug designation for
aplastic anemia.

"We look forward to providing the additional information that the FDA needs in
connection with our orphan drug status application for Aplastic Anemia. We
appreciate the very productive working relationship we have with the FDA, as
we present PLX cells as candidates for the treatment of a range of therapeutic
indications," stated Zami Aberman, Chairman and CEO of Pluristem.

About Orphan Drug Status

Orphan drug designation qualifies a company for several benefits under the
Orphan Drug Act of 1983 (ODA), as amended. These benefits include a 7-year
period of orphan drug exclusivity upon product approval, a tax credit for
certain clinical testing expenses for the orphan drug, written guidance on the
non-clinical and clinical studies needed to obtain marketing approval of an
orphan drug, and orphan drug grants.
