What is a clinical trial?
- Phase I and II trials are used to investigate a new treatment and determine the effective dosage. These usually involve a small number of patients.
- Phase III trials aim to confirm the benefits of this new treatment over the standard treatment. These trials involve a larger number of patients.
All medical research studies have to be approved before they can go ahead, which means the safety and ethical aspects have been considered by a panel of experts.
If you wish your child to take part in a clinical trial, you (or your child depending on their age), will need to give informed consent. This means that the trial has been explained to you, someone has told you what will be involved and you have agreed that your child will take part. You should be given at least 24 hours to think about your decision, if you need to do so.
If you like, ask if you can talk to a member of the research team so you can learn more about the study. It will be a matter of understanding the potential risks and benefits.
You don’t have to say yes, and your medical team will still give your child the best possible care if you decide not to go ahead. You can also choose to withdraw from a clinical trial at any time.
