Clinical studies, also called clinical trials, are conducted to collect data that evaluates the safety and benefit (efficacy) of a new drug in development. All clinical studies must follow a strict set of rules that are outlined in the protocol of the clinical study.
These rules inform the criteria for which types of patients can be included in the clinical study, procedures that must be followed, and the number of required clinical study visits. It is vital for patients who are selected to participate in a study to follow instructions from the research personnel who are conducting the trial.
All approved drugs have come to the market as a result of volunteers who have chosen to participate for one reason or another. Because participation in a clinical study is always voluntary, only you can decide if you would like to participate.
