A clinical trial is done to find out if a medicine or treatment
is safe and works well for treating a certain condition or
medicine or treatment must go through three phases before it is
approved for use by the U.S. Food and Drug Administration (FDA). A fourth phase happens after the medicine or treatment has been approved.
New combinations of approved medicines can
be studied in phase II, phase III, or phase IV trials.
