Fibrodysplasia Ossificans Progressiva (FOP) is a rare, severely disabling disease characterized by painful, recurrent episodes of soft tissue swelling (flare-ups) that result in abnormal bone formation in muscles, tendons, and ligaments. Flare-ups begin early in life and may occur spontaneously or after soft tissue trauma, vaccinations, or influenza infections. Recurrent flare-ups progressively restrict movement by locking joints leading to cumulative loss of function and disability. This 3-year, non-interventional, two-part, natural history study is designed to gain insight into total body HO, FOP disease progression, the impact of FOP on subjects' physical functioning, and clinical features and biomarkers that may be useful in the diagnosis and monitoring of disease progression. This natural history study will also provide important information to inform the design of subsequent interventional trials.
