They are randomised studies as well in which case its usually blinded to all involved in the study and a Placebo is used. Several hundred subjects are tested and the company is concerned here with safety and efficacy of the drug. Lasts for about several months to a few years. Phase III Trials: Several hundred to several thousand subjects are needed for ph. 3 trials. Usually safety and efficacy again are involved to check more closely though, on severity of the adverse events. These studies can last years. Looks at study benefits, risks, etc. Phase IV Trials: Phase IV involves marketing the drug. Once the study is ended in Phase III, the study needs to be marketed.
