(6)During screening, leukocyte count above the upper limit of normal (ULN), or neutrophils >80%, or presence of purulent sputum suggesting bacterial infection requiring systemic antibiotic therapy. (7)Alanine aminotransferase or aspartate aminotransferase =1.5 × ULN, or serum creatinine > ULN at screening. (8)Presence of severe or uncontrolled underlying diseases, including but not limited to: respiratory diseases (e.g., chronic obstructive pulmonary disease, bronchial asthma), hepatic insufficiency, renal insufficiency, cardiovascular diseases (e.g., congenital heart disease, chronic congestive heart failure, myocarditis; excluding hypertension and coronary artery disease without relevant symptoms), hematologic diseases, neurologic or neuromuscular diseases, metabolic or endocrine disorders, or psychiatric disorders.
