| Research into new medicines takes
place in four phases: |
| |
| Phase 1 Study of healthy
volunteers |
In Phase I clinical trials researchers
are often testing a treatment which may
be in the earliest stages of its
development in a small group of healthy
people (ie. usually 10 to 30
volunteers). The information gathered
from such trials will provide the
manufacturers with important data on how
the medicine is tolerated and
metabolised in healthy people and
whether any side effects have been
experienced by those taking part in the
trial.
These trials are an important step in
finding new treatments for the future
and it is for these studies that VEEDA
is looking for healthy volunteers. |

| Phase 2 Study of small groups
of patients |
In this phase we evaluate the
effectiveness of the substance in
treating patients with the disease for
which the medicine is being developed.
Again the safety of the substance is
carefully assessed with regular checks
on blood pressure, heart function and
blood and urine tests. |
| |
| Phases 3 and 4 Treatment of
groups |
In phase 3 much larger numbers of
patients are treated with the new
medicine and the drug is compared with
the best treatment already on the
market.
In phase 4 studies are carried out on
drugs that are already on the market in
order to discover more about them or to
look for new diseases that they may
treat. |
