R/R Aggressive B-cell NHL - Dose Level 1 (1×10⁶ Cells/kg)
Participants with relapsed/refractory aggressive B-cell non-Hodgkin lymphoma (NHL) received lymphodepleting chemotherapy (fludarabine 30 mg/m²/day and cyclophosphamide 500 mg/m²/day for 3 days) followed by infusion of autologous CD22 CAR T cells at Dose Level 1 (1×10⁶ cells/kg ± 20%).
R/R Aggressive B-cell NHL - Dose Level 2 (3×10⁶ Cells/kg)
Participants with relapsed/refractory aggressive B-cell non-Hodgkin lymphoma (NHL) received lymphodepleting chemotherapy (fludarabine 30 mg/m²/day and cyclophosphamide 500 mg/m²/day for 3 days) followed by infusion of autologous CD22 CAR T cells at Dose Level 2 (3×10⁶ cells/kg ± 20%).
R/R ALL - Dose Level 1 (1×10⁶ Cells/kg)
Participants with relapsed/refractory acute lymphoblastic leukemia (ALL) received autologous CD22 CAR T cells following lymphodepleting chemotherapy (fludarabine 30 mg/m²/day and cyclophosphamide 500 mg/m²/day for 3 days).

SECONDARY outcome

Timeframe: 28 days after infusion

Clinical response was assessed at Day 28 per modified International Working Group (IWG) criteria for acute lymphoblastic leukemia. Complete Response (CR) was defined as \<5% bone marrow blasts with hematologic recovery. CR with minimal residual disease (MRD-) required no detectable MRD by protocol-specified assay, whereas CR with MRD+ indicated detectable MRD. Progressive Disease (PD) was defined as increased bone marrow blasts or clinical progression.

Timeframe: 3 months after infusion

Population: 1 patient died in Complete Response but is excluded from 3 month analysis.

Clinical response was assessed at Month 3 per Lugano 2014 criteria for non-Hodgkin lymphoma. Complete Response (CR) was defined as disappearance of all evidence of disease. Partial Response (PR) was defined as ≥50% reduction in measurable disease. Stable Disease (SD) was defined as neither sufficient shrinkage for PR nor sufficient increase for PD. Progressive Disease (PD) was defined as appearance of new lesions or ≥50% increase in disease burden.
