Immune-mediated inflammatory diseases (IMIDs) are systemic inflammatory disorders driven by dysregulated immune responses that can affect multiple organs, including the lungs. Examples include Behçet disease, IgG4-related disease, and systemic sclerosis (SSc). IMID-related lung involvement may cause progressive lung damage, impaired lung function, disability, and increased mortality, but effective targeted treatment options remain limited. This clinical trial will study nebulized human umbilical cord mesenchymal stromal cell-derived extracellular vesicles, also called UC-EVs, in adults with recurrent or refractory IMIDs with lung involvement.
