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.
Electronic Clinical Outcome Assessment (eCOA)
eCOA (Electronic Clinical Outcome Assessment) is a digital version of a COA (Clinical Outcome Assessment), which measures and records how a patient is feeling or functioning. It is used as part of a clinical trial to measure the efficacy of a health intervention.
