A clinical trial is a research study that tests how medical treatments work. Clinical trials help to show if medical products, tests, and other treatments are safe and effective.

Clinical trials are done with people not animals. Some clinical trials use healthy people to test new treatments. Other trials use people who have a specific health problem that the research is studying. Whether you are a healthy or patient volunteer, you may not get any direct benefit from being in the clinical trial. The treatments may not work for you.


Read this page to help you talk to your healthcare provider about whether a clinical trial is right for you.

Why should women participate?

Medical products can affect men and women differently. Sometimes women have different side effects. It is important that women participate to show if products are safe and work well in both men and women.

More women are included in clinical trials than in the past. However, women still need to participate. Your participation may benefit other women by helping doctor’s learn more about women’s health.

What is FDA’s role?

FDA does not run clinical trials. FDA, other government agencies, and review boards set rules to protect people who participate in clinical trials. FDA also inspects some clinical trials for products regulated by FDA.

How does FDA use clinical trials data?

FDA uses the information from clinical trials and other sources to decide if a product is safe and effective. FDA reviews the information for certain kinds of new products before they are approved to be sold to the public. Not all products are tested in clinical trials.
