• Current or past confirmed diagnosis of asthma;
• History of other clinically significant pulmonary diseases apart from COPD: such as lung cancer, bronchiectasis, sarcoidosis, pulmonary fibrosis, interstitial lung diseases, cystic fibrosis, constrictive bronchiolitis, tuberculosis, or other active pulmonary diseases;
• Evidence of cor pulmonale with right heart failure；
• Diagnosed with α-1-antitrypsin deficiency;
• History of long-term oxygen therapy with >4 L/min;
• When using respiratory assistive oxygen, the subject's oxygen saturation should be ≥89%;
• Undergone lung volume reduction surgery or procedures within the 12 months prior to screening;
• Subjects participating or planning to participate in an intensive COPD rehabilitation program (subjects in the maintenance phase of a rehabilitation program are eligible for this study);
• History of lung transplantation;
• Any infection requiring hospitalization for ≥24 hours and/or treatment with oral, IV, or IM antibiotics within 4 weeks prior to screening or during the screening period;
• Upper or lower respiratory tract infections requiring antibiotic or antiviral medication within 4 weeks prior to screening or during the screening period;
• Moderate to severe COPD exacerbations within 4 weeks prior to screening or during the screening period.
• Received treatment with oral, IV, or intramuscular (IM) corticosteroids (>10 mg/day prednisone or equivalent dose) within 4 weeks prior to starting study medication;
• Received treatment with clinical trial medication, approved biologics (e.g., omalizumab, dupilumab, and/or anti-Interleukin 5 (IL-5) therapies) within 3 months prior to screening or within 5 half-lives of the drug (whichever is longer), or started or changed non-biologic immunomodulatory or immunosuppressive therapies;
• Receiving palliative care due to chronic respiratory disease, cardiovascular disease, endocrine and other systemic diseases, or cancer (e.g., for subjects with a life expectancy <12 months);
• Undergone major surgery within 8 weeks prior to screening or planning to undergo surgery that requires general anesthesia or hospitalization >1 day during the study period;
• Received or planning to receive live attenuated vaccine within 4 weeks prior to screening, during the screening period, or during the study period;
• Known immune deficiency, including but not limited to HIV infection;
• Elevated Aspartate Aminotransferase (AST), Alanine transaminase (ALT), or total bilirubin ≥2.0× the upper limit of normal (ULN) during the screening period;
• At screening, presence of any of the following: positive for hepatitis B surface antigen (HBsAg), positive for both hepatitis C virus antibody (HCV Ab) and hepatitis C virus RNA (HCV-RNA), positive for both specific and non-specific antibodies for syphilis (TP Ab);
