phase II/III clinical trial
(fayz … KLIH-nih-kul TRY-ul)
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.
