What else should I know before I take part in a clinical trial?

You should know as much about the clinical trial as possible. Plan ahead and write down the questions you want to ask. You might want to ask a friend or relative to come with you for support and to hear the responses to your questions.

Here is a list of sample questions:

  • What is the purpose of the study?
  • Why do researchers think that the treatment being tested may be effective? Has it been tested before? For how long?
  • Who is sponsoring or paying for the study?
  • Where is the study site? (Trials can take place in a variety of locations such as hospitals, universities, doctors’ offices or community clinics.)
  • How will the tests in the study compare to tests I would normally have if I were not in the study?
  • How often will I have to go to the study site?
  • Who will be in charge of my care?
  • What treatment(s) are involved? Will I know what treatment(s) I will be receiving?
  • Will I be able to take my regular medications during the study?
  • What medications, procedures or treatments must I avoid while participating in the study?
  • What are my responsibilities during the study?
  • Will I have to be in the hospital during the study?
  • Can anyone find out that I am participating in a study?
  • How do the possible risks and benefits of the study compare with approved treatments for me?
  • How will my safety be monitored?
  • Will the results of the study be provided to me? If so, when?
