What Is Covered Under Biosimilar Interleukins Market?

Biosimilar interleukins are defined as biosimilars produced by the body's leukocytes (white blood cells). Immune reactions are controlled by interleukins. Laboratory-produced interleukins are used as biological response modifiers to strengthen the immune system in cancer treatment. The different types of biosimilar interleukins are IL-17, IL-23, IL-1, IL-5, IL-6, and others. Interleukin 17 is a pro-inflammatory cystine knot cytokine family. In response to IL-23 stimulation, they are produced by a subset of T helper cells known as T helper 17 cells. The different applications include psoriasis, psoriatic arthritis, rheumatoid arthritis, asthma, inflammatory bowel disease (IBD), and others, and are distributed through various channels such as hospital pharmacies, online pharmacies, retail pharmacies, clinics, and research institutes.

What Is The Biosimilar Interleukins Market Growth Forecast?

The biosimilar interleukins market size is expected to see exponential growth in the next few years. It will grow to $41.22 billion in 2030 at a compound annual growth rate (CAGR) of 40.6%. The growth in the forecast period can be attributed to patent expirations of branded interleukins, expansion of biosimilar clinical pipelines, increasing physician acceptance of biosimilars, supportive government policies for biosimilar use, rising demand for affordable biologic cancer and immunology treatments. Major trends in the forecast period include rising adoption of biosimilar interleukins in autoimmune disease treatment, increasing demand for cost-effective alternatives to originator biologics, expansion of biosimilar approvals across multiple indications, growing use of interleukins in chronic inflammatory disorders, strengthening regulatory frameworks supporting biosimilar adoption.

What Is The Driver Of The Biosimilar Interleukins Market?

The increasing prevalence of autoimmune diseases such as psoriasis and rheumatoid arthritis is expected to boost the growth of the interleukin biosimilars market in the forecast period. Autoimmune disorders are conditions in which the immune cells cannot distinguish healthy cells from potentially dangerous antibodies. Biologic drugs such as anti-interleukin antibodies have shown significant clinical benefits in regulating the cells, and in directing proliferation, activation, and migration of the cells. For instance, in February 2024, according to reports published by the National Institutes of Health (NIH), a US-based biomedical research agency, the estimated annual increases in the global incidence and prevalence of autoimmune diseases are 19.1% and 12.5%, respectively. Therefore, the increasing prevalence of autoimmune diseases is increasing the demand for the biosimilar interleukins industry and is expected to drive the growth of the market.
