What Is a Clinical Trial?

Clinical Trials for Pain Management

The purpose of a clinical trial is to advance knowledge and improve quality of life. Clinical trials aim to make patient care better.

 A clinical trial is a research study that follows a very specific guideline. The clinical trial guideline—the study plan or protocol—outlines the study’s purpose, defines who can participate and who cannot (called inclusion and exclusion criteria), risks and possible benefits, and other important information. 
 
Many current clinical trials study prevention, diagnosis, and treatment of different types of chronic pain.
