Description
Inclusion Criteria:
Histologically confirmed CD22 + and/or CD19 + aggressive B-cell non-Hodgkin lymphoma (NHL), including the following types as defined by World Health Organization (WHO) 2016:
Diffuse large B-cell lymphoma (DLBCL); High grade B-cell lymphoma (HGBL); Primary mediastinal large B-cell lymphoma(PMBCL); T cell/histiocyte-rich large B-cell lymphoma (THRBCL); High grade follicular cell lymphoma Grade 3b (3bFL); Mantle cell lymphoma (MCL) except indolent; Other aggressive B-cell lymphomas.
- Disease refractory to first-line therapy or early relapse within 12 months of last treatment.
- Relapse or progressive disease (PD) ≥ 3 months after targeted CD19 therapy including CD19 CAR T cells or anti-CD19/anti-CD3.
- Successful leukapheresis assessment and T-cell preculture.
- Life expectancy > 3 months.
Appropriate organ function:
Creatinine < 1.6 mg/dL (140 µmol/L) or creatinine clearance ≥ 60ml/min; Alanine aminotransferase (ALT)/aspartate aminotransferase (AST) < 3 × upper limit of normal; Bilirubin < 2.0 mg/dL unless subject has Gilbert 's syndrome (< 3.0 mg/dL); Pulmonary reserve ≤ Grade 1 dyspnea and SPO2 > 91%; Cardiac ejection fraction ≥ 50% in the absence of oxygen, no evidence of pericardial effusion as determined by echocardiogram (ECHO), and no clinically significant electrocardiogram (ECG) findings.
Adequate bone marrow reserve was defined as:
Absolute neutrophil count (ANC) > 1000/mm3; Absolute lymphocyte count (ALC) ≥ 300/mm3; Platelet count ≥ 50,000/mm3. Hemoglobin > 7.0 mg/dL.
- Measurable or evaluable lesions according to "IWG response criteria for malignant lymphoma" (Cheson 2014).
- Patients have the ability to understand and are willing to provide written informed consent.
Exclusion Criteria:
- severe liver and kidney dysfunction (alanine aminotransferase, bilirubin, creatinine > 3 times the upper limit of normal);
- the presence of structural heart disease, and lead to clinical symptoms or abnormal heart function (NYHA ≥ 2);
- uncontrolled active infection;
- the presence of other tumors requiring treatment or intervention;
- the current or expected need for systemic corticosteroid therapy;
- pregnant or lactating women.
- Other psychological conditions that prevent patients from participating in the study or signing informed consent;
- According to the investigator 's judgment, the subject is unlikely to complete all protocol-required study visits or procedures, including follow-up visits, or fail to meet the requirements for participation in the study.
