Used in the treatment of inflammatory and autoimmune diseases by targeting and neutralizing granulocyte-macrophage colony-stimulating factor (GM-CSF), which plays a key role in the activation and proliferation of immune cells involved in inflammation. It has been investigated for conditions such as rheumatoid arthritis, multiple sclerosis, and pulmonary alveolar proteinosis. Additionally, it is explored in severe respiratory conditions, including acute lung injury and cytokine storms associated with infections like COVID-19, due to its ability to modulate excessive immune responses in the lungs.
