Biosimilar Interleukins Market Outlook 2025-2034: Market Share, and Growth Analysis By Type (IL-17, IL-23, IL-1, IL-5, IL-6), By Application (Psoriasis, Psoriatic Arthritis, Rheumatoid Arthritis, Asthma, Inflammatory Bowel Disease (IBD), Other Application

The Biosimilar Interleukins Market is valued at USD 9.3 billion in 2025 and is projected to grow at a CAGR of 34.7% to reach USD 135.9 billion by 2034.The Biosimilar Interleukins Market is emerging as a significant segment within the broader biosimilars landscape, driven by the growing demand for cost-effective alternatives to reference biologics. Biosimilar interleukins are used to treat a variety of conditions, including autoimmune diseases, inflammatory disorders, and certain types of cancer. As patents on original interleukin biologics expire, biosimilars provide an opportunity to lower healthcare costs and increase patient access to life-saving treatments. With rising healthcare expenditure and pressure to reduce treatment costs, biosimilar interleukins have gained attention from healthcare providers, payers, and regulatory authorities. Governments and private insurers are increasingly including biosimilars in their formularies and reimbursement plans, further boosting market adoption. In addition, ongoing advances in manufacturing processes and clinical development have improved the safety, efficacy, and accessibility of these products. However, challenges such as regulatory complexity, lengthy approval timelines, and resistance from physicians and patients familiar with the reference products can hinder market growth. Despite these obstacles, growing awareness of biosimilars’ clinical equivalence and cost benefits is expected to drive acceptance and expansion of the Biosimilar Interleukins Market over the coming years.
