• \. Women of childbearing age must be negative for blood Human Chorionic Gonadotropin (HCG) pregnancy test (by immunofluorescence method) at screening and baseline periods, and agree to use effective contraception for at least 1 year after infusion; and male subjects whose partners are women of childbearing age must agree to use effective barrier contraception methods and avoid sperm donation for at least 1 year after infusion.

You may not qualify if:

• \. The subject is currently suffered from or have suffered from other incurable malignant tumors within previous 5 years, except in skin basal cell cancer、carcinoma in situ or breast cancer have received curative treatment with no recurrence within the past 3 years)
• \. History of organ transplantation
• \. A history of mental disorders, which may affect compliance with this protocol or lead to failure in signing the Informed Consent Forms(ICF)
