clinical trials

A type of research study that is used to evaluate the effects of new drugs, medical devices, or other treatments on participants in scientifically controlled settings. They are required for government approval of new drugs or devices. Trials can assess the safety and efficacy of an experimental therapy to determine whether the new intervention is better than standard therapy, or to compare the efficacy of two standard or marketed therapies.
