When a drug is ready for a clinical trial, it has already been through many tests in laboratories and we know enough about the drug in order to safely give it to humans.
What we need to find out more about in clinical trials is how much of a new drug is the best dose for a person, what the side effects are and whether the new drug works better than the old ones that are being used.
Clinical trials have very strict regulations to make sure that people taking part are not at any risk during the trial. People in clinical trials are always checked and watched carefully by doctors and nurses to make sure that they are OK and to see how the treatment is working.
If you want to find out more we have linked to Maggie’s CancerLinks where you will be signposted to high quality information about clinical trials.
