The I-SPY 2 Trial is an investigational drug trial for newly diagnosed patients with locally advanced breast cancer. An investigational drug has been approved for testing in people by the U.S. Food and Drug Administration (FDA) but has not yet been approved for widespread use. A clinical trial tests how well investigational drugs work and whether they are safe to use.
