Before each new drug/ device/ treatment makes it to the established treatment shelf, it has to pass through a lengthy research and approval process which takes around 12 to 16 years. The whole process from the lab to an established form of treatment is called as clinical research and this is where several of professionals are required. The discoveries & innovations in the field medicine have come about with Biomedical Research-of which Clinical Research is one important division. Clinical Research deals with finding the causes of diseases; & thereby find effective remedies & preventive measures against them. If a clinical research study involves testing or studying a drug or medical device to see if it is a safe and effective treatment for people, it is called a “trial.” For example, a clinical trial may test the effectiveness of a new drug for treating Parkinson’s disease. Many new medicines and drugs are found to work in the researcher’s lab, and to be safe and effective in animal tests. But drugs and devices must be proven to be safe and effective for people before the Food and Drug Administration (FDA) can approve them and doctors can prescribe them. The FDA has strict rules that govern how clinical trials are conducted. These rules are designed to ensure the safety of those who participate. The most important application of Clinical Research is the study of new drugs and their effects on human subjects with the aim to determine is safety & efficacy which is conducted through an organized Clinical Trial.
