Clinical Trials

Before medications are approved by the U.S. Food and Drug Administration (FDA) or before certain therapy methods are widely accepted as effective, they are tested on people who volunteer to participate in a clinical trial.

ResearchMatch brings together two groups of people who can benefit each another: those trying to find research studies and researchers looking for participants in their studies. Research is a way to discover knowledge that can have a positive impact on the health of society. Most research studies need a certain number of people to participate, but many end too early because too few volunteers join them. Even when enough people join research studies, it may be difficult to find the right match for them. ResearchMatch helps solve this problem by matching you with researchers who need volunteers like you. It is a free and secure registry, and you can be involved in its mission of helping make a real difference in people’s health in the future. Anyone can join, and ResearchMatch can help match you with any type of research study, ranging from surveys to clinical trials, always giving you the choice to decide what studies may interest you.
