What are clinical trials?

Clinical trials are studies of new kinds of cancer treatments. Doctors use clinical trials to learn how well new treatments work and what their side effects are. Promising treatments are ones that work better or have fewer side effects than the current treatments. People who participate in these studies have access to these treatments before the U.S. Food and Drug Administration (FDA) approves them. People who join trials also help researchers learn more about cancer and help future cancer patients.
