TEL AVIV, Sept 14 Pluristem Therapeutics
(PSTI.O) said early clinical trials show its placenta-derived
cell therapy is safe and improves quality of life in patients
with degenerative disorder peripheral artery disease (PAD).

The company is targeting 2013 to bring the product to market
and is in talks with large drug firms for a licensing deal.

PAD is an obstruction of blood vessels, usually in the leg,
causing pain, difficulty in walking and leading eventually to

The Phase I trials, conducted at three university hospitals
in the United States and one in Berlin, show the cells are
effective in treating the end stage of PAD, called critical limb
ischemia, the Israel-based biotech company said on Tuesday.

Pluristem plans advanced trials in the first half of 2011.

Unlike many other companies that use embryonic stem cells,
Pluristem harvests cells from the placenta after a woman gives
birth, so there is no ethical issue on using embryos.

“We have proved we can use the placenta as a source for a
product that doesn’t require a match between the donor and
patient,” Chief Executive Zami Aberman told Reuters.

While an estimated 20 million people in the United States
suffer from PAD, Pluristem is targeting the 2.5 million who are
in the end stage. Insurance companies pay about $10 billion a
year to treat those patients.

“We assume … we can get 30 to 50 percent of this $10
billion market,” Aberman said.

Pluristem estimates it can slash reimbursement costs of
insurance companies by about 50 percent, as the cost of treating
PAD using its therapy, called PLX-PAD, is significantly cheaper
than current methods, which run to around $40,000 per year.

Pluristem is in talks with large pharmaceutical companies in
the United States, Europe and Japan to market the treatment
though Aberman would not disclose names.

He said Pluristem was seeking a licensing deal similar to
those signed by Pfizer Inc (PFE.N) with stem cell firm Athersys
(ATHX.O) and Genzyme GENZ.O with Osiris Therapeutics OSIR.O.

Present treatment for PAD include a bypass to improve
circulation, drugs to improve bloodstream and oxygen chambers.

“These can stop progress of the disease for a while but do
not change the situation,” Aberman said.

Pluristem’s clinical trials showed patients experienced
improvement in bloodstream, pain and quality of life for six
months following a 20-minute session of injections.

“The most important thing is to reduce the amputation rate,”
Aberman said. “What we envision is a treatment once in six

Pluristem plans to launch trials for other applications over
the next few quarters and expects to begin bringing these
applications to market within the next few years. Applications
being looked at are neuropathic pain, orthopaedic injuries and
several auto-immune disorders.
