Clinical Trials

What is a Clinical Trial?

A clinical trial is a way to test an intervention—a new drug, device (like a pacemaker), a new procedure, or even changes in behavior—to see what its impact is by following a research plan. The intervention also might be an existing drug, device or procedure used for a different disease or in a different way. In a clinical trial, researchers might be testing for safety and effectiveness of the intervention, or they may be testing to see what the benefits of the intervention might be and how it might improve lives. The intervention is often compared with a different intervention that already exists or with no intervention. Often, some trial participants are given a placebo, a harmless drug, device or procedure so participants don’t know whether or not they are getting the intervention being tested. When people are given the intervention or no intervention (or a placebo) at random, this is called “randomization.”
