ABSTRACT:
Clinical trials are the set of procedures in medical research and drug development that are conducted to allow safety and efficacy data to be collected for place only interventions. These trials can take place only after satisfactory information has been gathered on the quality of the country where the trial is taking place.
Depending on the type of product and the stage of its development, investigators enrol healthy volunteers and patients into small pilot studies, followed by larger scale studies in patients that often compare the new product with the currently prescribed treatment. As positive safety and efficacy data are gathered, the number of patients is typically increased. Clinical trials can vary in size from a single centre in one country to multicenter trials in multiple countries.
