• Clinical trials, also called clinical studies, are carefully controlled research studies that test new ways to treat diseases, such as cancer. Clinical trials are conducted in a series of steps, called phases. Each phase aims to answer specific medical questions. Once a new treatment has been shown to be safe and effective in clinical trials, it may become the standard of care. You can get answers to commonly asked questions about clinical trials and search for clinical trials for the type of cancer you have.
