Vall d’Hebron Hospital is right now the world leader
of investigation of a new medicine against cancer. A new medicine has been discovered
and essayed with some patients. But this new medicine is still experimental.
Doctors say that this new medicine behaves in a different way from the others.
The good results of this investigation give the
possibility of developing new drugs which could be used to treat different
kinds of cancer and it this happens this treatment could be a revolutionary
one
.
The new drug operates from the inside of the tumoral
cell disabling the activity of the gens that give support to cancer.
This is about molecules called ARNi that would be
equal to genetic antibiotics. So, if antibiotics can treat illnesses caused by
bacterium, the ARNi, will let treat illnesses causes by dangerous genetic
cells.
The gens are made of ADN and from this point of they
produce little molecules called ARN messenger (ARNm) and from these ones
proteins start developing. If these proteins are good, the cells can work well,
so it’s then when the ARNi comes out to avoid making bad proteins. The ARNi inactivates
the ARNm and it stops producing bad cells.
To carry out this idea to to real world it’s a great
challenge. The ARNi can be utilized to destroy bad gents, but the problem is
that they get degraded in the blood. And the question is: How can web ring them
up to the cells that have to be treated?
Alnylam, an American pharmaceutical company thought
that if the ARNi was put in fat capsules, they would be the “taxi” thought the
blood and these capsules would bring the ARN up to the bad cells and heal them.
Some animals have been tested in this way and it’s has
been discovered that it’s possible to do it. After this, Alnylam got in touch
with Vall d’Hebron and this same test was tested with humans, with cancer. The
result was spectacular. The aim of this experiment was to know if the ARNi
could be useful with humans, and if it was, to carry on with the investigation.
This test was so successful that even patients with
metastasi, got excellent results.
“We only had one opportunity". If the test failed the
investigation would be paralyzed” said Tabernero, who directs the High School
of Oncology in Val d’Hebron.
Two more Spanish hospitals and six American hospitals,
were adhered in this research. Like Clinico de Valencia, Virgen del Rocio and Dana-Ferber in Boston.
In this clinical research, only participated people
who had very advanced cancer, people who didn’t have any possibility therapy
and people who had several metastasis, were accepted.
Te results were given to the Discovery Cancer magazine
and they demonstrate that the ARNi, goes to the tumoral cells of the liver and
to other body organs and don’t have very important secondary effects.
The cancer has stopped progressing in four patients.
One girl with uterous cancer with metastasis, the tumor mass had disappeared
after two years of treatment.
“This is only the start" said Taberneto. The next step
is to define the type of tumour that this therapy can help and to discover
which gens have to be disabled in each tumour. Inn theory, this treatment of
ARNi could be good in any kind of Cancer, as the develop in the same way, but
Tabernero says that It’s very important to go “step by step”. If everything
works all right, and we don’t have any complications, one treatment against
cancer supported with ARNi, it could be applied in five years.
