| What are the different phases of a clinical trial? Phase I: What is the safe dose? How does the treatment
affect the human body? How should the treatment be given?
Phase II: Does the treatment treat the disease or cure the
condition?
Phase III: Is the treatment better than, the same as, or worse
than the standard (or most widely accepted) treatment? If there is no
standard treatment available, is it better than, the same as, or worse than a
placebo?
