Who can join

Age: 3 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Aged ≥3 and ≤70 years, gender and race unrestricted.
• Bone marrow examination confirms the diagnosis of acute B-cell lymphoblastic leukemia (B-ALL) and meets one of the following conditions:
• Relapsed B-ALL: ① Relapse within 12 months after the first remission; or ② Relapse after salvage chemotherapy in first-line/multi-line treatment; or ③ Relapse after autologous or allogeneic hematopoietic stem cell transplantation; Refractory B-ALL: ① Failure to achieve complete remission after 2 cycles of standardized induction chemotherapy; or ② Failure to achieve complete remission after salvage chemotherapy in first-line/multi-line treatment;
• Ph+ALL subjects are eligible if they meet one of the following criteria: ① Relapse or refractory after receiving at least 2 tyrosine kinase inhibitors (TKIs) treatments; if accompanied by TKI-resistant mutations such as T315I/A, V299L, F317L/V/I/C, G250E, Y253H, E255K/V, F359V/C/I, subjects are not required to receive at least two TKI treatments; or ② Unable to tolerate TKI treatment; or ③ Contraindications to TKI treatment.
• The proportion of bone marrow blasts during the screening period is ≥5% (morphological).Expression of CD19 on bone marrow or peripheral blood tumor cells is detected during the screening period.
• Organ function and laboratory tests meet the following criteria:
• Serum total bilirubin <2× upper limit of normal (ULN), serum ALT and AST both <3× ULN, serum creatinine <1.5× ULN; Coagulation function: International normalized ratio (INR) ≤1.5× ULN, or prothrombin time (PT) ≤1.5× ULN; Transthoracic echocardiogram shows left ventricular ejection fraction (LVEF) ≥50%; Resting oxygen saturation (SpO2) ≥92% in ambient air; Estimated survival period of more than 3 months;
• ECOG score 0-2;
• Fertile women must agree to use highly effective contraception from at least 28 days before leukapheresis to 6 months after CAR-T cell infusion. Their partners, fertile men, must agree to use effective barrier contraception from the start of leukapheresis to 6 months after CAR-T cell infusion, and should not donate semen or sperm during the entire trial period.

You may not qualify if…

• Suffering from genetic syndromes such as Fanconi anemia, Kostmann syndrome, Shwachman syndrome, or any other known bone marrow failure syndromes;
• History of allergy to any component of the cellular product;
• Presence of active central nervous system leukemia (CNSL) at screening;
• Patients with purely extramedullary relapse;
• Received allogeneic hematopoietic stem cell transplantation (HSCT) within 3 months before screening or experienced grade II to IV active graft-versus-host disease (GVHD) within 4 weeks before infusion;
• Significant cardiovascular dysfunction within 12 months before screening, including but not limited to: New York Heart Association (NYHA) class III or IV heart failure, myocardial infarction, unstable angina, uncontrolled or symptomatic atrial arrhythmias, any ventricular arrhythmias.
• Presence or suspicion of uncontrollable active infection requiring intravenous therapy (excluding simple urinary tract infections, bacterial pharyngitis);
• Subjects with a history of other primary cancers, excluding the following:
• Non-melanoma skin cancers such as basal cell carcinoma that have been cured by resection; Cervical carcinoma in situ, localized prostate cancer, ductal carcinoma in situ with disease-free survival ≥2 years after adequate treatment;
• Subjects with autoimmune diseases requiring treatment, immunodeficiency, or requiring immunosuppressive therapy;
• Received live attenuated vaccines within 4 weeks before screening, or planned to receive live attenuated vaccines during the study.
