Frequently Asked Questions
A clinical trial is a type of research study. The most commonly performed clinical trials evaluate new drug, medical device, biologics, or other interventions on patients in strictly scientifically controlled settings, and are required for regulatory authority (in the USA, the Food and Drug Administration) approval of new therapies. Trials may be designed to assess the safety and efficacy of an experimental therapy, to assess whether the new intervention is better than standard therapy, or to compare the efficacy of two standard or marketed interventions.
