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.
