Clinical Study of Anti-CD56-CAR-T in the Treatment of Relapsed/Refractory NK/T Cell Lymphoma /NK Cell Leukemia Phase 2 20
Single-center, Open, One-arm Clinical Study of the Safety and Efficacy of Anti-CD56-CAR T Therapy in Relapsed Refractory NK/T Cell Lymphoma /NK Cell Leukemia

ExperimentalCAR-T Cell Infusion Pretreatment was initiated at -5 days prior to CAR T cell reinfusion, and CAR T cell therapy was performed 2 days after completion of chemotherapy. All patients were pretreated with FC regimen, fludarabine: 30mg/m2×3 days, cyclophosphamide: 750mg/m2×1 day. Anti CD56-CAR T cells were transfused back 2 days after chemotherapy. The freeze-thawed cell product solution is injected back into the body as soon as the patient...Show More | Anti-CD56 CAR T CAR T cells were pretreated at -5 days before retransfusion (FC regimen: fludarabine: 30mg/m2×3 days, cyclophosphamide: 750mg/m2×1 day). Anti CD56-CAR T cells were transfused back to the patient 2 days after the end of chemotherapy. 30 to 60 minutes before CAR T cell infusion, patients were given 325 to 650 mg of acetaminophen orally to prevent infusion-related reactions; If fever occurred on the day of CAR T cell in...Show More |
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Overall response rate (ORR) | CR+PR.1.Leukemia:Complete Response (CR):Bone marrow blast cells \<5%; primitive cells without Auer bodies; without extramedullary leukemia;Absolute blood neutrophil count was\> 1.0\*10\^9 / L (1000 / μ L);Platelet count\> 100\*10\^9 / L (100 000 / μ L);Not dependent on RBC infusion.Partial Response (PR):Only for Phase I and II clinical trials;Bone marrow cells were reduced to 5 - 25% and at least 50% compared with before treatment;Hematological parameters met the same criteria for CR. 2.Lymphoma:CR:All the evidence of the lesions disappeared.PR:The lymph nodes shrank with no new lesions. | From 1 month to 1 year. |
progression-free survival (PFS) | The time between treatment and observation of disease progression or death from any cause. | From 1 month to 1 year. |
overall survival (OS) | The time from the start of treatment to death from any cause. | From 1 month to 1 year. |
event-free survival (EFS) | The time between the start of treatment and the occurrence of any event, including disease recurrence, death, and so on. | From 1 month to 1 year. |
Safety evaluation index | 1\. Detection of CRS-related factors: such as IFN, IL-6, TNF, IL-10, IL-4, CRP, etc;2. Testing of various laboratory items: blood routine, coagulation function, blood film observation, liver function, renal work, electrolytes, blood glucose, cardiac enzymes, blood cells, T cell subsets, immunoglobulins, etc;3.Adverse events and serious adverse events were observed. | From 1 month to 1 year. |
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
CAR T cell index of correlation | The presence of peripheral blood and bone marrow CAR-T cells were measured regularly by using flow cytometry, quantitative PCR techniques. | From 1 month to 1 year. |
- Patients or their legal guardians voluntarily participate and sign the informed consent;
- Male or female patients aged 18-70 years (including 18 and 70 years);
- The patient was diagnosed as NK/T cell lymphoma /NK cell leukemia by pathology or flow cytometry, and currently has no effective treatment options, such as relapse after chemotherapy or hematopoietic stem cell transplantation; Alternatively, patients voluntarily choose to administer anti-CD56-CAR T cells as salvage therapy.
- The following two categories are included:(1)NK/T cell lymphoma;(2) NK cell leukemia.
- Subject:
(1)There was no remission or residual lesions after treatment, and HSCT (auto/allo-HSCT) was not suitable; (2)Relapse occurred after CR, and HSCT (auto/allo-HSCT) was not suitable; (3)Patients with high risk factors; (4)Relapse or no remission after hematopoietic stem cell transplantation or cellular immunotherapy.
6. Measurable or evaluable lesions;
7. The patient's main tissues and organs function well:
- Liver function: ALT/AST < 3 times the upper limit of normal (ULN) and total bilirubin ≤34.2μmol/L;
- Renal function: creatinine < 220 μmol/L;
- Lung function: indoor oxygen saturation ≥95%;
- Cardiac function: left ventricular ejection fraction (LVEF) ≥40%.
8. The patients had not received any anti-cancer treatment such as chemotherapy, radiotherapy, immunotherapy (such as immunosuppressive drugs) within the first 4 weeks of enrollment, and their previous treatment-related toxic reactions had recovered to ≤ grade 1 at the time of enrollment (except low toxicity such as hair loss);
9. The patient's peripheral shallow venous blood flow is smooth, which can meet the needs of intravenous infusion;
10. Patients with ECOG score ≤2 and expected survival time ≥3 months.
