They are willing to use very effective and reliable methods of contraception within 1 year after receiving study treatment. It is absolutely prohibited to donate eggs within 1 year after receiving study treatment infusion during the study period; Male participants who had active sex with women with reproductive potential were willing to use very effective and reliable methods of contraception within 1 year after receiving study treatment. All male participants were absolutely forbidden to donate sperm within 1 year after receiving study treatment infusion during the study period.

Exclusion Criteria:
