Global market valuation was derived through revenue mapping, treatment volume analysis, and epidemiology-based patient forecasting. The methodology included:
Identification of 35+ key biopharmaceutical manufacturers and diagnostic companies across North America, Europe, Asia-Pacific, and Latin America
Product mapping across monoclonal antibodies (eculizumab, inebilizumab, satralizumab), immunosuppressants (mycophenolate, azathioprine), corticosteroids, and symptom management therapies
Analysis of reported and modeled annual revenues specific to NMOSD therapeutic portfolios
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (prevalent patient population × treatment penetration × ASP by country) and top-down (manufacturer revenue validation) approaches to derive segment-specific valuations
Integration of epidemiological data from rare disease registries and national health statistics to validate addressable patient populations
