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. |
