  11. Patients with severe respiratory diseases at the time of enrollment (before apheresis), such as interstitial lung disease, active tuberculosis, etc., investigator considered unsuitable for enrollment.
  12. According to the judgment of the investigator, patients with any serious or uncontrollable systemic disease, systemic complications, other serious concurrent diseases (such as hematophilic syndrome, etc.), special tumor conditions may unsuitable for entering this study or affect Protocol compliance, or significant interference with the correct evaluation of the safety, toxicity, and effectiveness of the study drug.
