What is a clinical trial?

Clinical trials

A clinical trial is a biomedical/health-related research study into the effects on humans of a new medical treatment (medicine/drug, medical device, vaccine or new therapy), sometimes called an investigational medicinal product (IMP). Before a new drug is authorised and can be marketed, it must pass through several phases of development including trial phases in which its safety, efficacy, risks, optimal use and/or benefits are tested on human beings. Existing drugs must also undergo clinical testing before they can be used to treat other conditions than that for which they were originally intended.
