Primary Outcome Measures :
  1. Occurrence of study related adverse events [ Time Frame: 12 Months ]
    Incidence and severity of Treatment emergent adverse events


Secondary Outcome Measures :
  1. Maximum concentration (Cmax) of EXP039 in the peripheral blood [ Time Frame: up to 12 months ]
    Detect CAR-T copies number by qPCR

  2. Time to maximum concentration (Tmax) of EXP039 in the peripheral blood [ Time Frame: up to 12 months ]
    Detect CAR-T copies number by qPCR

  3. Tlast of EXP039 in the peripheral blood after infusion [ Time Frame: up to 12 months ]
    Detect CAR-T copies number by qPCR

  4. AUC0h-28d of EXP039 in the peripheral blood [ Time Frame: 4 weeks ]
    Detect CAR-T copies number by qPCR

  5. Objective response rate (ORR) [ Time Frame: 4 weeks, 12 weeks, 6 months, 9 months, 12 months ]
    Complete response (CR) rate plus partial response (PR) rate by Lugano 2014 criteria

  6. Duration of response (DOR) [ Time Frame: up to 12 months ]
    The time from the date of first response (PR or better) until the date of disease progression after EXP039 infusion

  7. Progression-free survival (PFS) [ Time Frame: 4 weeks, 12 weeks, 6 months, 9 months, 12 months ]
    The time from EXP039 infusion to the date of progression as assessed by Lugano 2014 criteria or death

  8. Overall survival rate (OSR) [ Time Frame: 12 weeks, 6 months, 12 months ]
    The time from EXP039 infusion to the date of death
