Study Arms:
- CD19-STAR-T cells (Type: EXPERIMENTAL): CD19-STAR-T cells are prepared via lentiviral infection. 5 days prior to infusion of STAR-T cells, subjects receive fludarabine at dose 30mg/m2/day and cyclophosphamide treatment at dose 250mg/m2 for 3 days and take a rest for 2 days before infusion.

Based on this trial design, predict the completion outcome and termination type (if applicable).
