| phase I clinical trial | <pharmacology> The earliest stage clinical trial for studying an experimental drug in humans. Phase I trials are generally comparatively small and are used to determine toxicity and maximum dose. They provide an initial evaluation of a drug's safety and pharmacokinetics-how the drug is absorbed, what tissues it reaches and how long it takes to leave the body. Such studies also usually test various doses of the drug (dose-ranging) to obtain an indication of the appropriate dose to use in later studies. The patients in these trials usually have advanced disease and have already received best available chemotherapy, therefore, seeing a repose is significant partially because this means there is a lack of cross-resistance between two anti-cancer drugs.

| phase II clinical trial | <pharmacology> Usually focus on the activity of the new product as a single agent in a noncomparative, open study. (31 Dec 1997) |
| 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. (31 Dec 1997) |
