What is the trial “phase?”
Cancer clinical trials are usually conducted in a series of steps, called “phases.” Each phase is designed to answer a separate research question. Phase I trials evaluate safety. Phase II trials measure effectiveness. Phase III trials test the new drug against the best existing treatment (often referred to as the standard of care). Phase IV trials are conducted to further evaluate new uses or long-term effects of the treatment.
