Withdrawing from a study
Participating in research is voluntary and you can stop (withdraw) at any time.
You may want to leave because you:
- no longer have the time or energy for it
- don’t feel it is helping
- have side effects or your health is worsening
- move away from the treatment centre
- change your mind.
If you do decide to withdraw from a clinical trial, you will receive the standard treatment that is currently the best option for you. You may be asked why you are withdrawing from the trial – you do not have to give a reason, but it can help the research team understand more about the needs of participants if you do. You may also be asked if the team can still collect some information about your health. This can help them learn more, but it is your choice.
