What is a clinical study?
Clinical research takes place in clinical studies (also called clinical trials). It is essential for advancing the management or treatment of medical conditions and diseases.One reason why clinical studies are required is to test the safety and effectiveness of an investigational treatment for medical conditions and diseases. However, in some clinical studies, researchers may want to collect information about the course of a disease or condition and its impact on participants’ lives. These types of studies do not include any investigational treatment. They are called noninterventional or observational studies.
The SPIRIT Study is an observational study which means it only collects information and does not involve any treatment or therapy.
