phase III clinical trial (medicine)


phase III clinical trial
<pharmacology> An advanced stage clinical trial that should conclusively show how well a drug works as compared to other treatments.

Phase III trials are large, frequently multi-institution tests. They generally compare the relative value of the new drug compared with the current standard treatment and measure whether a new drug extends survival or otherwise improves the health of patients on treatment (clinical improvement) rather than just provide surrogate marker data. These studies generally last longer and are larger than phase II trials.
