Clinical trials follow a typical series from early, small-scale, Phase 1 studies to late-stage, large scale, Phase 3 studies. What are the Clinical Trial Phases? Preclinical research is not done with people. There are several stages, or “phases,” of a clinical trial. During Phase 1 studies, researchers test a new drug in normal volunteers (healthy people). Phase 4 Clinical trials follow a particular timeline, from early, small-scale, phase 1 studies to late-stage, large-scale, phase 3 studies. In Phase II, the clinical study is expanded and vaccine is given to people who have characteristics (such as age and physical health) similar to those for whom the new vaccine is intended. Each phase tends to have a different purpose and helps answer different questions. Clinical Research, Clinical Study, Clinical Trial, and Clinical Protocol all concern the same topic. A study of clinical trials conducted in the United States from 2004 to 2012 found the average cost of Phase I trials to be between $1.4 million and $6.6 million, depending on The drug development process will normally proceed through all four phases over many years.
