    What it is

    Clinical research studies (also called clinical trials) test how well different types of medical care work and if they’re safe, like how well a cancer drug works. Clinical research studies may involve diagnostic tests, surgical treatments, medicine, or new types of patient care. They may:

    • Study how well new treatments and tests benefit patients
    • Compare different treatments for the same condition to see which treatment is better
    • Study new ways to use existing treatments
