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.


First-in-class drugs

A first-in-class drug refers to a pharmaceutical that utilizes a "new and unique mechanism of action" to treat a specific medical condition. These drugs represent novel approaches to addressing diseases and often provide innovative treatment options. They may introduce a completely new therapeutic approach or target previously unexplored pathways.
