IL-4 (Interleukin 4) is a cytokine secreted by various cells like the mast cells, Th2 cells, Eosinophils and Basophils. The effect of IL-4 is mediated via the IL-4 receptor alpha chain, which, upon activation by its ligand, dimerizes to produce either a Type-1 signaling complex or a Type-2 signaling complex. Type-2 expressed on the non-hemopoietic cells, like endothelial cells, responds to IL-4. Therefore, IL-4 functions as a potent regulator of immunity. IL-4 has been associated with the pathophysiology of allergy, hypersensitivity, and other immunological diseases. It is also related to the pathology of neurological disorders such as Alzheimer’s disease, Multiple Sclerosis, and Glioblastoma Multiforme, thus, it has a profound role in maintaining the brain’s immunity- memory and learning. Studies also say that IL-4 rescues B-cells from apoptosis and is responsible for Ig subtype switching to IgG1 and IgE. IL-4 along with IL-13, has been associated with the pathophysiology of many diseases Asthma, Atopic Dermatitis (AT), and others. Extensive research is being conducted globally to discover new and novel molecules to be used, like dupilumab which is used for the treatment of many indications like Atopic Dermatitis. The development and launch of new products will thus increase the market’s revenue in the forecasted years. For instance, according to a research article, the prevalence of Prurigo Nodularis (PN) in 2020 in the USA was estimated to be 72 per 100,000 adult people. Companies are trying to develop new molecules to target these indications, and many of them are being evaluated in clinical trials. For instance, Dupixent (dupilumab) is approved in the USA and Europe for treating Atopic Dermatitis e(AD).

A number of these inhibitors are in the market, while many are in ongoing clinical trials. Various companies have various products in their pipelines, with 6 products in various stages of clinical trials – 1 in Phase 4, 3 in Phase 3, 17 in Phase 2, and 7 in Phase 1 of the clinical trials.
