Clinical
Trials are medical research studies involving people. They aim to find
out:
 |
if
a new treatment or medical procedure is safe |
|
if it has side
effects |
|
whether it works
better than the treatments already in use |
| Clinical
trials are carried out in 3 phases: |
| Phase
1 |
trials
are carried out with small numbers of patients to see if the new treatment
or drug is safe or has any harmful effects |
| Phase
2 |
trials
test the new treatment to see if it is likely to work for a particular
cancer. Only treatments that get through phase 1 and 2 trials enter
phase 3 |
| Phase
3 |
trials
test the new treatment to see if it works better than the standard
treatments available |
