The global Interleukin (IL) market is anticipated to grow at a significant CAGR during the forecast period (2021-2027). Interleukin (IL) is a group of naturally occurring proteins. They mediate communication between cells and regulate cell growth, differentiation, and motility. The major factor driving the demand for interleukin (IL) inhibitors is the increasing prevalence of cancer across the globe. 

According to the National Cancer Institute (NCI), it was estimated that 1,806,590 new cases of cancer will be diagnosed in the US with a mortality rate of 606,520 people in 2020. Furthermore, there were 18.1 million new cases and 9.5 million cancer-related mortalities globally in 2018 which is anticipated to rise to 29.5 million and the number of cancer-related mortalities to 16.4 million by 2040. Hence, the increasing prevalence of cancer is driving the demand for interleukin (IL) as it supports immune system cells to grow and divide more quickly, which in turn, is driving the growth of the market.

Some major players in the market include Johnson & Johnson Services, Inc., GlaxoSmithKline, and Novartis International AG, among others. The market players are contributing significantly to the growth of the market by the adoption of various strategies including mergers & acquisitions, geographical expansion, partnerships and collaborations, and new product launches, to stay competitive in the market. For instance, in July 2020, Janssen announced the approval of TREMFYA (guselkumab) from the US Food and Drug Administration (FDA). It is used for the treatment of adult patients with active psoriatic arthritis (PsA) which selectively inhibits interleukin (IL)-23.
