A drink containing liquid aspirin could extend the lives of thousands of brain cancer patients, according to breakthrough research.
British experts have found that the simple
drug can cross the ‘blood-brain barrier’ - a hurdle which has so far stopped
cancer drugs attacking brain tumours.
Scientists will today announce the results
of early tests which show liquid aspirin is ten times more effective than any
existing chemotherapy at killing brain cancer cells.
And the team is confident that even more
powerful combinations could be created if liquid aspirin is combined with
cancer drugs, enabling strong drugs to properly attack brain tumours for the
first time.

More than 16,000 people each year in Britain
are diagnosed with a brain tumour, yet campaigners have long warned that
patients are left behind by a system which allocates them just 1 per cent of
the national cancer research spending.
Less than 20 per cent of brain cancer
patients survive more than five years, compared to 87 per cent for breast
cancer and 98 per cent for testicular cancer.
The standard treatment involves surgery,
where possible, to remove the tumour, followed by radiotherapy and then
chemotherapy.
But chemotherapy is rarely effective because
the drug, which is delivered into the blood supply via a drip, cannot properly
reach the tumour.
This is because brain cells are separated
from the blood supply via the blood-brain barrier - a membrane which divides
blood cells from cerebral fluid.
Most drug molecules are too large to get
through this barrier, but the new research - to be presented today at the Brain
Tumours 2016 conference in Warsaw, Poland - reveals that specially-formulated
aspirin acts as a ‘Trojan horse’ to carry drugs through the barrier.
The breakthrough was made possible by a
small company, working out of a family kitchen in Manchester, which has managed
to make true liquid aspirin for the first time.
‘Soluble’ aspirins currently on the market
are not completely soluble - contain grains that are too big to get through the
membrane.
But Manchester-based Innovate Pharmaceuticals
- comprised of brothers Simon and Jan Cohen with local A&E consultant Dr
James Stuart - found that combining aspirin with a ‘solubiliser’ and a
‘stabiliser’ resulted in a truly liquid state.
The Portsmouth University team, whose
research was funded by the Brain Tumour Research charity, found in lab tests
that the solution showed huge promise.
They tested the liquid aspirin solution -
known for now as IP1867B - on cancer cells from adults and children with a
common and aggressive form of brain tumour called a glioblastoma.
And they found it was ten times more
effective than any combination of other currently used drugs.
This is because aspirin itself has an
ability to kill cancer cells. But if they add cancer drugs to the solution -
which they have already started testing - they expect power of the treatment to
substantially improve.
Sue Farrington Smith, chief executive of
Brain Tumour Research, said: ‘This is a potential game-changer for research
into brain tumours and clearly shows what sustainable research is able to
achieve.
‘It is science like this that will enable us
to eventually find a cure for this devastating disease which kills more
children and adults under the age of 40 than any other cancer.’
All three ingredients are already approved
for human use, meaning that trials should be quicker than otherwise for a new
drug.
Experts expect the first human trials to
start within two to three years.
Dr James Stuart, chief medical officer at
Innovate Pharmaceuticals, said: ‘IP1867B represents a major step forward in
therapeutics.
‘We are excited by the studies to date and
hope that our future studies will prove this to be the breakthrough that
patients have been waiting for.’
Chemotherapy is rarely

Aspirin has been used as a pain killer for
thousands of years, since the Ancient Egyptians found that an extract of willow
bark helped mothers cope with the pain of child birth.
But in recent years scientists have found
that the cheap drug has many more applications.
Because it thins the blood and reduces inflammation, scientists are increasingly finding that it can ward off the threat of many diseases, including stroke, heart disease and several forms of cancer.
