What are the phases of clinical trials?

Physicians describe the series of steps (called phases) of clinical trials. Each phase is designed to answer important questions that lead to the next phase. The purpose of Phase 1 is to test a new drug or treatment in a small group of people for the first time in order to evaluate safety, safe dose range, and side effects. In Phase 2, the drug or treatment is tested in a larger group of people to see if it is effective and to further evaluate safety. The purpose of Phase 3 is to compare the new drug or treatment to current treatments (called standard of care), and collect information that will allow it to be used safely. This phase can include thousands of patients and many years of study. Based on the results of Phase 3, a medicine can receive FDA approval for use in the wider population. Phase 4 studies are done after the drug or treatment has been FDA approved, to gather information on long-term effect in various populations and any side effects associated with long-term use. If a patient is thinking about a clinical trial, it’s important to understand which phase the trial is in and what the unique research plan or “protocol” is for the study, and the eligibility criteria.
