Patients considering participating in a clinical trial should talk about it with their physicians and medical caregivers. They should also understand the credentials and experience of the staff and facility involved in conducting the study. Questions to ask a physician or medical caregiver:

How long will the trial last?
Where is the trial being conducted?
What treatments will be used and how?
What is the main purpose of the trial?
How will patient safety be monitored?
Are there any risks involved?
What are the possible benefits?
What are the alternative treatments besides the one being tested?
Who is sponsoring the trial?
Do I have to pay for any part of the trial?
What happens if I am harmed by the trial?
Can I opt to remain on this treatment, even after the trial?

In some studies, participants receive a physical examination and their medical histories are reviewed by either the study physician or a research staff member. The participant’s health will continue to be monitored during and after the trial. A detailed description of what is expected of volunteers will be outlined in consent forms along with specific clinical trial information.
