Used in the treatment of autoimmune and inflammatory diseases by targeting and neutralizing granulocyte-macrophage colony-stimulating factor (GM-CSF), this antibody helps reduce the activation and recruitment of immune cells such as macrophages and neutrophils. It is being investigated for conditions like rheumatoid arthritis, multiple sclerosis, and severe lung inflammation, including in cases of hyperinflammatory responses such as those seen in advanced respiratory infections. By inhibiting GM-CSF signaling, it modulates the immune response, helping to prevent tissue damage and control excessive inflammation.
