Exclusion Criteria: * Current or past asthma, or other clinically significant respiratory disease that may confound assessment. * Clinically significant uncontrolled comorbidities that increase risk or interfere with participation/outcomes. * Immunodeficiency/immune dysregulation, active autoimmune disease requiring systemic immunosuppression, or significant opportunistic infection history. * Active clinically significant infection or recent infection requiring systemic therapy; recent protocol-defined COPD exacerbation. * Current/recent malignancy (except low-risk, adequately treated cancers per protocol) or clinically significant abnormal screening labs. * Prohibited recent vaccines or therapies, prior relevant biologic/targeted therapy exposure, severe hypersensitivity to biologics/IMP, pregnancy/breastfeeding, or inability to comply (including substance abuse), per investigator judgment.
