Phase III trials

The third stage in a series of trials to determine the safety and efficacy of a drug before it reaches the public. At this stage, trials can involve thousands of patients, and seek to gather additional information on a drug after preliminary evidence suggesting its effectiveness has been obtained. The benefit to risk relationship of the drug is also established and comparison studies are often made with existing treatments
