What Are Clinical Trials?

Clinical trials are scientific studies conducted to discover more effective and efficient ways to prevent, screen for, diagnose and treat disease. Clinical trials assist in obtaining information about what type of medical approach has the most efficacy with certain illnesses or groups of people. Clinical trials produce high-quality data used for healthcare decision making and each individual clinical trial has a protocol or action plan that is followed while conducting the specific trial. The plan describes what will be done in the study, the manner in which it will be conducted and why each part of the study is necessary. Each clinical trial is overseen by a Principal Investigator. Physicians are the only individuals who are qualified to be Principal Investigators to ensure the safety and well-being of all study participants.
