In order to gather both qualitative and quantitative insights, supply-side and demand-side stakeholders were interviewed during the primary research process. CEOs, VPs of clinical development, heads of regulatory affairs, and commercial directors from biopharmaceutical companies, experts in rare diseases, and suppliers of diagnostic technologies were examples of supply-side sources. Board-certified neurologists, neuroimmunologists, multiple sclerosis specialists, medical directors of infusion centers, hospital pharmacy directors, and procurement leads from academic medical centers, specialty neurology clinics, and hospitals with specialized neuroimmunology departments were among the demand-side sources. In addition to gathering information on treatment acceptance trends, diagnostic algorithm preferences, pricing and reimbursement dynamics, and unmet medical requirements in NMOSD management, primary research verified market segmentation and product pipeline timelines.
Primary Respondent Breakdown:
By Designation: C-level Primaries (32%), Director Level (31%), Others (37%)
By Region: North America (38%), Europe (25%), Asia-Pacific (28%), Rest of World (9%)
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
