Segmentation by types of therapy further refines the market taxonomy into pharmacologic agents, biologic therapies, device‑based solutions, and transplant procedures. Within pharmacologic agents, subtypes such as ursodeoxycholic acid, antibiotics, and immunosuppressants address cholestasis, bacterial overgrowth, and immune modulation respectively, together representing roughly 40 % of treatment spend. Biologic therapies—subdivided into anti‑TNF agents and anti‑IL‑12/23 monoclonal antibodies—target inflammatory pathways and currently occupy an emerging 15 % share, reflecting ongoing clinical trials and limited approvals. Device‑based solutions, including biliary stents and dilatation balloons, fall under endoscopic intervention and contribute about 10 % of the market, primarily through procedural reimbursement. Liver transplantation, the definitive surgical subtype, commands the remaining 35 % of expenditure, driven by high procedural costs and post‑operative care. This type‑based breakdown clarifies how each therapeutic modality underpins the overall market valuation.
