How to Find a Clinical Trial

Are you trying to find a clinical trial to enter?

Each year, researchers recruit many volunteers into such trials to evaluate new medical treatments, drugs, or devices. Ultimately, clinical trials seek better ways to treat different diseases and conditions. Not only might the trial participants benefit, so could patients in the future.

But you (or your doctor) have to know how to find those trials.

How to Find a Clinical Trial

A good starting place is www.clinicaltrials.gov. This web site, sponsored by the National Institutes of Health, offers information on more than 125,000 clinical trials in 180 countries. Some of those are recruiting patients; other trials are completed or terminated.

To start your search:

  • Go to www.clinicaltrials.gov.
  • Click on the link, "Search for Clinical Trials," on the home page.
  • Enter your search terms -- for example, a disease or intervention and a location: "heart attack" AND "aspirin" AND "California." Separate your multiple search terms with a capitalized "AND."

Need more help? Click on the "Background Information" link on the homepage. Then go to "Online Training," which features animated tutorials on how to perform searches: You'll learn how to tell open trials that are recruiting new participants (marked in green) from those that are closed to new volunteers (marked in red). You can also hide studies that are not recruiting new volunteers.

If you want to see all studies listed for your condition, see "Study Topics" on the right side of the home page. You'll find four links that allow you to list all studies by condition, drug intervention, location, or sponsor.

Studies that are recruiting will name a sponsor (for example, "University of Michigan" or "National Heart, Lung, and Blood Institute"). Further down the page, you'll also find a contact person, whom you can reach by phone or email to ask about participating.

What Questions Should You Ask?

If you find a clinical trial that interests you, feel free to ask many questions so that you understand as much as possible. Here are 13 useful questions, noted by ClinicalTrials.gov, to discuss with members of the health care team involved with the clinical trial:

  1. What is the purpose of the study?
  2. Who is going to be in the study?
  3. Why do researchers believe the experimental treatment being tested may be effective? Has it been tested before?
  4. What kinds of tests and experimental treatments are involved?
  5. How do the possible risks, side effects, and benefits in the study compare with my current treatment?
  6. How might this trial affect my daily life?
  7. How long will the trial last?
  8. Will hospitalization be required?
  9. Who will pay for the experimental treatment?
  10. Will I be reimbursed for other expenses?
  11. What type of long-term follow-up care is part of this study?
  12. How will I know that the experimental treatment is working? Will results of the trials be provided to me?
  13. Who will be in charge of my care?
