According to our (Global Info Research) latest study, the global Mepolizumab market size was valued at US$ 2732 million in 2025 and is forecast to a readjusted size of US$ 7259 million by 2032 with a CAGR of 16.3% during review period.
Mepolizumab is a humanized anti‑interleukin‑5 (IL‑5) monoclonal antibody drug. It specifically targets and binds to the IL‑5 cytokine, blocks its combination with receptors on the surface of eosinophils, and inhibits the activation, proliferation and survival of eosinophils, thereby reducing eosinophilic inflammatory responses in the respiratory tract and the whole body. It is mainly applied in the treatment of inflammatory diseases such as eosinophilic asthma and chronic rhinosinusitis with nasal polyps. With stable clinical efficacy and favorable safety, it can effectively reduce the risk of severe exacerbations and provide a long‑acting targeted treatment option for eosinophil‑related respiratory diseases.In 2025, global Mepolizumab (Nucala) production reached approximately 1.71 million vials.
Mepolizumab, the world’s first approved anti‑IL‑5 monoclonal antibody, targets eosinophil‑related diseases mediated by interleukin‑5. It has built a diversified product portfolio centered on severe asthma, with gradually expanded indications including chronic rhinosinusitis with nasal polyps and eosinophilic granulomatosis with polyangiitis. Its market development is driven by the popularization of precision diagnosis and treatment as well as the general shift toward biological agents. Global regulatory authorities continue to expand its applicable populations and age ranges, meanwhile promoting its penetration from hospital settings to outpatient and home care scenarios. In terms of competition, GSK occupies a leading position, continuously optimizing its indication spectrum through clinical research and developing next‑generation long‑acting formulations to improve patient compliance and market competitiveness. Regional market growth benefits from improved medical infrastructure and rising awareness of rare and refractory inflammatory diseases, with emerging markets such as the Asia‑Pacific region showing great growth potential. Overall, key market drivers include improved diagnostic capabilities, greater accessibility of biological drugs, and optimized long‑term treatment costs. Major challenges involve difficulties in target patient screening, inconsistent reimbursement policies, and competition from similar therapeutic drugs. The overall industry development is characterized by indication expansion, regional market penetration and continuous product iteration.
