TEL AVIV, Jan 18 Israeli stem cell therapy
company Pluristem Therapeutics (PSTI.O) has won U.S. and
European approval to conduct an advanced trial for its treatment
of peripheral artery disease, a degenerative disorder.
The Israeli biotech company has completed early Phase I
trials and said on Tuesday it will be able to conduct an
advanced Phase II/III trial in both Europe and the United States
to treat the end stage of peripheral artery disease (PAD), known
as critical limb ischemia.
PAD is an obstruction of blood vessels, usually in the leg,
causing pain, difficulty in walking and leading eventually to
Chief Executive Zami Aberman said Pluristem will also
conduct a Phase II trial to test its treatment on an earlier
stage of the disease, placing it on track for a preventative
treatment in addition to treating amputation-destined cases.
The treatment for both stages of the disease targets a 20
million patient market.
"We believe that 2014 will be the time for approval and
marketing in Europe and the United States for critical limb
ischemia," Aberman told Reuters.
"It's a very unique situation that we can discuss with both
the FDA (U.S. Food and Drug Administration) and EMA (European
Medicines Agencies) the same clinical study protocol."
The Phase II trial will involve up to 150 patients in
Germany and the United States while the Phase II/III trial will
be conducted throughout Europe and the United States and enroll
up to 500 patients.
"It's great news for us," Aberman said, adding the company
will need to raise money to fund the trials.
Pluristem's shares were halted for trading in Tel Aviv
pending the announcement.
In December the company filed for a shelf offering of up to
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.
Pluristem said in September early clinical trials in the
United States and Europe show its placenta-derived cell therapy
is safe and improves quality of life in patients with PAD.
Aberman has said Pluristem is in talks with large
pharmaceutical companies in the United States, Europe and Japan
to market the treatment though he would not disclose names.
"We have a lot of interest," he said.
