What is a clinical study?

A clinical study, also called a clinical trial, is a research test to see if an investigational medicine is safe and effective in human volunteers. It compares the investigational medicine to a placebo (a treatment with no active ingredients). These medicines have not been fully approved by the FDA (Food and Drug Administration) or other health organizations. However, they can still be given to people as part of the study. Participants play a vital role in advancing medicine for current and future generations.
