  • 12)Poorly controlled diabetes mellitus. 13)Active systemic infection requiring treatment. Systemic corticosteroid therapy (except for temporary use, e.g., for examination or prophylaxis of allergic reactions) or immunosuppressants within 28 days before enrollment.
  • 15)Patients who have received antineoplastic drugs (e.g., chemotherapy agents, molecular targeted therapy agents, or immunotherapy agents) within 28 days before randomization.
  • 16)Surgical pleurodesis or pericardium within 28 days prior to enrollment. 17)Major surgery within 4 weeks or minor surgery within 7 days before the first dose, without full recovery. Patients scheduled for major surgery during the study period are excluded (video-assisted thoracoscopic surgery or diagnostic procedures are not considered exclusions if recovery is adequate).

  • 19)Active tuberculosis. 20)Positive serology for human immunodeficiency virus (HIV-1/2 antibody), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody. Patients who are HBsAg-positive may be enrolled if hepatitis B virus DNA is below the lower limit of detection.
  • 21)Any other severe medical or psychiatric condition, or abnormal laboratory findings, that in the investigator's judgment would increase the risk of study participation, compromise protocol compliance, or interfere with the interpretation of study results.
  • 22)Participation in another clinical trial and receipt of an investigational product within 4 weeks prior to the first dose.
  • 23)Pregnancy, lactation, or intention to become pregnant during the study period.
  • 24)Positive urine pregnancy test within 72 hours before treatment initiation (if urine test is positive or indeterminate, a confirmatory serum pregnancy test is required).
