Description:
A study that
          tests how well a new treatment works for a certain type of
          cancer or other disease and compares the new treatment with
          a standard treatment. Phase II/III clinical trials may also
          provide more information about the safety and side effects
          of the new treatment. Combining phases II and III may allow
          research questions to be answered more quickly or with
          fewer patients. Also called phase 2/phase 3 clinical trial.
