Blind to be cured with stem cells
Sarah-Kate Templeton, Health Editor
BRITISH scientists have developed the world's first stem cell therapy to
cure the most common cause of blindness. Surgeons predict it will become a
routine, one-hour procedure that will be generally available in six or
seven years' time.
The treatment involves replacing a layer of degenerated cells with new
ones created from embryonic stem cells. It was pioneered by scientists and
surgeons from the Institute of Ophthalmology at University College London
and Moorfields eye hospital.
This week Pfizer, the world's largest pharmaceutical research company,
will announce its financial backing to bring the therapy to patients.
The treatment will tackle age-related macular degeneration (AMD), the
most common cause of blindness. It affects more than 500,000 Britons and the
number is forecast to increase significantly as people live longer. The
disease involves the loss of eye cells.
Under the new treatment, embryonic stem cells are transformed into
replicas of the missing cells. They are then placed on an artificial membrane
which is inserted in the back of the retina.
Tom Bremridge, chief executive of the Macular Disease Society, said:
"This is a huge step forward for patients. We are extremely pleased that the
big guns have become involved, because, once this treatment is validated, it
will be made available to a huge volume of patients."
Embryonic stem cells have the ability to develop into all types of body
tissue. Their use is controversial, however, because it involves the
destruction of human embryos.
Laboratory trials completed by the British team have demonstrated that
stem cells can prevent blindness in rats with a similar disease to AMD. They
have also successfully tested elements of the technology in pigs.
The team is led by Professor Pete Coffey, director of the London Project
to Cure Blindness, working alongside Lyndon da Cruz, a surgeon at
Moorfields.
Coffey said the treatment would take "less than an hour, so it really
could be considered as an outpatient procedure. We are trying to get it out as
a common therapy".
He welcomed Pfizer's agreement to manufacture the membranes, saying:
"This is a major development because of the size of the partner. We need a big
pharmaceutical company to scale it up.
"We have nearly 14m people within Europe with AMD. This will ensure that
the therapy gets through to clinical trials in a safe and effective
manner."
Professor Peng Khaw, director of the Biomedical Research Centre at
Moorfields and the UCL Institute of Ophthalmology, added: "This shows that stem
cell therapy is coming of age. It offers great hope for many sufferers
around the world who cannot be treated with conventional treatment." He added:
"All my patients say to me is, 'When will this stem cell treatment be ready?
I want it now'."
Pfizer's role would be crucial in bringing production of the membranes to
an industrial level.
The team is applying for regulatory approval for trials from the
Medicines and Healthcare products Regulatory Agency, the Human Tissue Authority and
the gene therapy advisory committee.
The clinical trial, due within two years, is expected to be the second in
the world to use embryonic stem cells on humans. The first, on patients
with spinal cord injuries, will start this year in America.

White House, who has not responded at all.
