- Expected survival is greater than 6 months; 14. The subjects have sufficient levels of functional organs during screening;
- Female participants of childbearing age must undergo a serum pregnancy test during screening and before receiving pre-treatment chemotherapy, and the result must be negative. They are willing to use highly effective and reliable methods of contraception within one year after using the study treatment;
- Male participants who engage in active sexual activity with women with reproductive potential must be willing to use highly effective and reliable methods of contraception within one year after using the study treatment. Moreover, all males are strictly prohibited from donating sperm within one year after receiving research treatment infusion during the study period.
You may not qualify if…
