Primary refractory disease despite at least 2 cycles of an intensive chemotherapy regimen designed to induce remission B. Refractory disease despite salvage therapy C. 2nd or greater relapse D. Any relapse after allogeneic hematopoietic stem cell transplantation
2. Informed consent explained to and signed by patient/parents or legal guardian.
3. The Karnofsky (age ≥10 years)/Lansky (age \<10 years) performance status score over 50 points.
4. Expected to survive for more than 3 months.

10. Meets eligibility criteria to undergo autologous apheresis.
Exclusion Criteria:
1. Isolated extra-medullary disease relapse.
2. Active CNS involvement of ALL (CNS Grade 3 per National Comprehensive Cancer Network guidelines).
3. Severe, uncontrolled bacterial, fungal or viral infections (Active hepatitis B or C, history of HIV infection)
4. Pre-existing significant neurological disorder.
5. Active significant acute graft versus host disease (GVHD) or moderate/severe chronic GVHD requiring systemic steroids or other immunosuppressants within 4 weeks of enrolment.
6. Pregnant or lactating female.
7. The patient did not agree to use effective contraception during the treatment period and for the following 1 year.
8. A history of other malignant tumors.
9. Receiving systemic steroids therapy exceeding the equivalent of 0.5 mg/ kg/day of methylprednisolone, in the 7 days prior to CAR T-cell infusion
