What are Phase III clinical trials and why are they important in drug development?

Phase III clinical trials are large studies which confirm drug safety and efficacy. They contain a greater number of participants than Phase II trials so that safety and efficacy can be validated in a larger population. The trials almost always randomly assign participants to one of two groups, the control group or the treatment group. Phase III trials usually include participants of different race, ethnicity and gender, in order to see how a drug acts on a diverse group of people.
