Immune-Mediated Disease Biologics Market Size and Forecast

The global immune-mediated disease biologics market was valued at USD 94.6 billion in 2025 and is projected to reach USD 176.8 billion by 2032, growing at a CAGR of 9.4%. Market growth is supported by expanding biologic use across earlier treatment lines and additional disease indications. Long-term maintenance therapy significantly increases per-patient treatment duration. Strong uptake in rheumatoid arthritis, psoriasis, and inflammatory bowel disease continues to anchor revenues. Biosimilar competition moderates pricing in some regions but expands patient access. Overall growth remains robust due to chronic disease prevalence and sustained innovation.

Market Overview

The immune-mediated disease biologics market includes biologic drugs designed to selectively modulate immune system activity in autoimmune and inflammatory conditions. These therapies target cytokines, immune cell receptors, and signaling pathways responsible for chronic inflammation and tissue damage. Biologics have transformed disease management by offering superior efficacy and disease control compared to conventional therapies. Clinical adoption is highest in moderate-to-severe disease stages but is moving earlier in treatment algorithms. Long-term safety monitoring and immunogenicity management are integral to therapy success. The market serves hospitals, specialty clinics, and long-term care settings globally.
