Types segmentation categorizes treatments by disease etiology and pathology. Key subtypes include neurodegenerative disorders (e.g., ALS, Parkinson’s), inherited metabolic diseases (e.g., Niemann-Pick), and autoimmune-related conditions (e.g., MS). Neurodegenerative disorders represent 50% of the market, driven by aging populations and high R&D funding. Inherited metabolic diseases, though rare, account for 30% due to orphan drug incentives and targeted therapies. Autoimmune conditions contribute 20%, with biosimilars reducing costs. This market taxonomy underscores how disease prevalence, regulatory support, and therapeutic innovation shape market dynamics, with each type offering unique revenue opportunities for pharmaceutical players.
