What is a clinical research study?

A clinical research study is a study involving people that seeks to answer a specific scientific or health question. The study may involve the testing of an unproven drug, an investigational medical device, a diagnostic tool, a food or drink, or an existing therapy used in a new but untested way to see if the product is helpful in preventing, diagnosing, or treating a disease or condition. The study may involve an existing product used in a way that was previously found to be safe and effective in order to learn more about the product’s safety. Or the study may involve only the collection of health information in order to study a health issue in the general population.
