A clinical trial is a scientific experiment in patients (or occasionally healthy volunteers) to determine if a medical intervention (drug, device or procedure) will work in the way it is intended (i.e. that it is effective, or works for treating the disease being studied) and to determine if there are safety or tolerability issues. Most frequently, this is done by comparing one treatment to another, where one treatment could be the new drug and the other could be an older drug or a placebo. Frequently, patients are randomly given one treatment or the other and in a double blind study, neither the doctor nor the patient knows which treatment each patient has received until the end of the study.
When the trial is completed, the scientific report written to describe the methods and results of the trial for submission to regulatory authorities is called the Clinical Study Report or CSR. This is written in a standardised format that is agreed upon by the major regulatory authorities in the US, EU and Japan.
