Natural History Study

A natural history study is a preplanned intended to track the course of the disease. Its purpose is to identify demographic, genetic, environmental, and other variables (e.g., treatment modalities, concomitant medications) that correlate with the disease’s development and outcomes. Natural history studies are likely to include patients receiving the current standard of care and/or emergent care, which may alter some manifestations of the disease.

It is an online software tool used in clinical trials to manage patient randomization, drug supply, and trial site communication. The system allows study personnel to log into a secure website and manage trial-related activities in real-time. IWRS is a type of IRT that specifically uses web-based technology.
