Global market valuation was derived through revenue mapping, prescription volume analysis, and treatment course modeling. The methodology included:
Identification of 50+ key manufacturers across North America, Europe, Asia-Pacific, Latin America, and Middle East & Africa, including innovator companies, generic manufacturers, and emerging biosimilar developers
Product mapping across oral tablets (2.5mg, 5mg, 7.5mg, 10mg, 15mg), subcutaneous injections (auto-injectors, prefilled syringes), and intravenous formulations
Analysis of reported and modeled annual revenues specific to methotrexate portfolios, including both branded (Rheumatrex, Trexall, Otrexup, Rasuvo) and generic formulations
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (prescription volume × average treatment cost by country/region) and top-down (manufacturer revenue validation) approaches, adjusted for off-label usage patterns and compassionate access programs
Cross-validation against national health expenditure data and insurance claims databases to derive segment-specific valuations across cancer chemotherapy protocols, rheumatoid arthritis management, and psoriasis treatment pathways
