Pluristem to Initiate a Phase I/II Clinical Trial in Muscle Injury

Product Candidate Targets Orthopedic and Sports Injuries, Addresses a
Multi-Billion Dollar Annual Market

HAIFA, Israel, Nov. 14, 2012 (GLOBE NEWSWIRE) -- Pluristem Therapeutics, Inc.
(Nasdaq:PSTI) (TASE:PLTR), a leading developer of placenta-based cell
therapies, today announced it has initiated a Phase I/II clinical trial to
evaluate the safety and efficacy of its PLacental Expanded (PLX) cells in the
treatment of muscle injury. As previously reported, the Paul Ehrlich Institute
(PEI), the German competent authority in the European Union, has granted the
Company clearance to start the trial which will be conducted at the Klinik für
Orthopadie on the campus of the Charité Universitatsmedizin in Berlin,
Germany.

"Pluristem considers this clinical trial to be our entry into the orthopedic
and sports medicine markets. The response of the gluteal muscle to our PLX
cells will be an indication for us of how well our cells would help various
muscle injuries," stated Zami Aberman, Chairman and CEO of Pluristem.

Study Summary:

In this Phase I/II trial, the muscle injury studied will be the trauma
sustained to the gluteal buttock muscle that occurs during hip replacement.
The most common type of hip replacement surgery involves splitting the gluteal
muscle to obtain access to the hip joint. Previous muscle injury animal
studies have demonstrated a significant improvement in rehabilitation function
and time by using PLX cells over placebo. The endpoint of this study is to
observe if there is an improvement in the functional recovery of the gluteal
muscle as measured by maximal contraction force.

This randomized, double blinded, Phase I/II trial will evaluate the safety and
efficacy of two doses of PLX cells versus placebo administered via
intramuscular injections directly into the site of the lacerated gluteal
muscle before suturing. The study cohort is comprised of approximately 18
patients equally divided between a high and low dose PLX cell group and
placebo group.
