What are clinical trials?

Clinical trials are research studies that test new and potentially better ways of improving peoples’ health. They are an important process to assess whether promising approaches to prevention, diagnosis and treatment are possible, safe, and effective in humans. Some trials also look at ways of enhancing a person’s quality of life.

Clinical trials are the final stages of a long and careful process that often starts many years earlier. Trials are the link between scientific discoveries made in the laboratory and making new treatments available for people with lung disease.
