Brief summary
This is a single arm, open-label, early phase Ⅰ study, to determine the safety and efficacy of CD19-TriCAR-T and CD19-TriCAR-SILK cell therapy in Non-Hodgkin lymphoma treatment.
Detailed description
CD19-TriCAR contains an anti-CD19 scFv, a PD-L1 blocker, and a cytokine complex, enabling the CD19-TriCAR-T/SILK to simultaneously targeting the CD19 positive Non-Hodgkin lymphoma，blocking the inhibitory PD-L1 signal and stimulating innate T/NK cell activation and expansion, thus make it a tri-functional CAR (Tri-CAR). CD19-TriCAR-T is an autologous tri-functional CAR-T cell therapy, CD19-TriCAR-SILK is an Allogeneic tri-functional CAR-NK cell therapy, patients ineligible for leukapheresis or CAR-T therapy will be recommended for CD19-TriCAR-SILK therapy.
Interventions
BIOLOGICALCD19-TriCAR-T/SILK
A conditioning chemotherapy regimen of fludarabine and cyclophosphamide may be administered, followed by a single infusion of CD19-TriCAR-T cells or 4 repeat infusions of CD19-TriCAR-SILK cells.

Inclusion criteria
1. All subjects must personally sign and date the consent form before initiating any study specific procedures or activities; 2. All subjects must be able to comply with all the scheduled procedures in the study; 3. Refractory or relapsed malignant Non-Hodgkin lymphoma, defined as one or more of the following: Relapsed in 6 months after most recent therapy; Progressive disease in standard chemotherapy; Disease progression or relapsed in ≤12 months of ASCT; 4. At least one measurable lesion per revised IWG Response Criteria; 5. Aged \<70 years; 6. Expected survival ≥12 weeks; Eastern cooperative oncology group (ECOG) performance status of≤2; 7. Systematic usage of immunosuppressive drug or corticosteroid must have been stopped for more than 4 weeks; 8. All other treatment induced adverse events must have been resolved to ≤grade 1; 9. Laboratory tests must fulfill the following criteria: ANC ≥ 1000/uL, HGB\>70g/L, Platelet count ≥ 50,000/uL, Creatinine clearance ≤1.5 ULN, Serum ALT/AST ≤2.5 ULN, Total bilirubin ≤1.5 ULN (except in subjects with Gilbert's syndrome);
Exclusion criteria
1. Presence of fungal, bacterial, viral, or other infection that is hardly to control（defined by investigator）; 2. Patients with symptomatic central nervous system metastasis, intracranial metastasis, and cancer cells found in cerebrospinal fluid are not recommended to participate in this study. Symptom free or post-treatment stable disease or disappearance of lesions should not be excluded. The specific selection is ultimately determined by the investigator; 3. Lactating women or women of childbearing age who plan to conceive during the time period; 4. Active infection with hepatitis B (HBsAG positive) or hepatitis C virus (anti-HCV positive); 5. Known history of infection with HIV; 6. Subjects need systematic usage of corticosteroid; 7. Subjects need systematic usage of immunosuppressive drug; 8. Planed operation, history of other related disease, or any other related laboratory tests restrict patients for the study; 9. Other reasons the investigator consider the patient may not be suitable for the study.
