About

This is a single arm, open-label, single-center, phase 1/2 study, to determine the safety and efficacy of TriCAR-T-CD19, an autologous tri-functional anti-CD19 chimeric antigen receptor (CAR)-positive T cell therapy, in refractory/Relapsed Non-Hodgkin Lymphoma (NHL).

Full description

The tri-functional anti-CD19 chimeric antigen receptor contains an anti-CD19 scFv, a PD-L1 blocker, and a cytokine complex, enabling the TriCAR-T-CD19 to simultaneously targeting the CD19 positive NHL，blocking the inhibitory PD-L1 signal and stimulating T/NK cell activation and expansion.

Enrollment: 6 estimated patients

Sex: All

Ages: 18 to 68 years old

Volunteers: No Healthy Volunteers

4. Chemotherapy-refractory disease, defined as one or more of the following: Relapsed in 6 months after most recent therapy; Progressive disease in the standard R-CHOP or CHOP chemotherapy; Disease progression or relapsed in ≤12 months of ASCT (must have biopsy proven recurrence in relapsed subjects); If salvage therapy is given post-ASCT, the subject must have had no response to or relapsed after the last line of therapy.
5. No available standard therapy;
6. At least one measurable lesion per revised IWG Response Criteria;

11. All other treatment induced adverse events must have been resolved to ≤grade 1;
12. 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);
13. Female must be not pregnant during the study.

Exclusion criteria

1. History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast) or follicular lymphoma unless disease free for at least 3 years;
2. History of allogeneic stem cell transplantation;
3. Prior other CAR therapy or other genetically modified T cell therapy;
4. Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring IV antimicrobials for management. Simple UTI and uncomplicated bacterial pharyngitis are permitted if responding to active treatment;
5. Subjects with detectable cerebrospinal fluid malignant cells, or brain metastases, or with a history of CNS lymphoma, cerebrospinal fluid malignant cells or brain metastases;
6. Lactating women;
7. Active infection with hepatitis B (HBsAG positive) or hepatitis C virus (anti-HCV positive);

9. History of any gene therapy;
10. Subjects need systematic usage of immunosuppressive drug;
11. Known history of infection with HIV;
12. Planed operation, history of other related disease, or any other related laboratory tests restrict patients for the study;
