What is a “Placebo” in a clinical trial and is it always used?

Physicians explain what a “placebo” is in a clinical trial, and if is it always used. Placebos can have some real impacts on a clinical trial. Researchers know that there is an effect from the trial, but they need to isolate that effect to make sure it is really the medicine or device that is causing that effect. Sometimes patients get better anyway because they’re part of the clinical trial process, or for other reasons. A common clinical trial scenario is where researchers are building on a standard of care option by adding an experimental or new drug or tool to that standard option. In that case, the clinical trial design might call for half of the patients getting the standard approach plus the experimental medication, and the other half getting the standard approach plus a placebo. But none of the patients would get only a placebo. The placebo may look like medicine but it has no active ingredient in it. Patients are still getting the good care that they normally would get, they are just not part of the group that is getting the new experimental drug. This clinical trial context is typically “blinded”, meaning neither the doctors nor the patients know which group they are in. This ensures there are no doctor or patient biases that impact the outcomes of the clinical trial. At the end of the day, everyone wants to be able to rely on the conclusions drawn from the clinical trial because they can help millions of people in the future.
