4. Respiratory or systemic infections requiring anti-infective therapy within 1 month prior to randomization;
5. Acute exacerbation of IPF within 4 months prior to randomization;
6. Use of any medication known to cause or worsen pulmonary fibrosis, as assessed by the investigator, within 3 months prior to screening;
7. History of smoking within 3 months prior to screening, or unwillingness to quit smoking throughout the study period;
8. Presence of clinically significant cardiovascular, cerebrovascular, hematological, neurological, psychiatric, or metabolic disease at screening, or plans for major surgery during the study period;
