Companies such as AbbVie, Johnson & Johnson, Novartis, and Roche (Genentech) maintain a dominant position due to their established blockbuster franchises in major autoimmune indications and their aggressive R&D pipelines focused on next-generation targets. Their control over global distribution and established relationships with payers and key opinion leaders (KOLs) creates significant barriers to entry for smaller firms.
