Brief Summary

Despite the use of monoclonal antibodies, checkpoint inhibitors, and bispecific T cell adapters (BiTE) Immunotherapies such as chimeric antigen receptor (CAR) T cells have completely changed the treatment methods of various cancers. However, only limited responses were observed in T cell diseases, In CD30 positive PTCL and CTCL patients. The use of BV in and pembroluzimab (Programmed cell death receptor 1) in the treatment of ENKTL. Although some promising results have been observed for (PD-1) inhibitors, these positive results are limited to specific subtypes of T cell diseases. CAR T Cell therapy in recurrent/refractory B-cell malignant tumors is very successful, the Food and Drug Administration (FDA) has approved two CAR T Cell therapy for the treatment of this type of disease. However, using this technology to treat T-cell malignancies has always been difficult, mainly due to the lack of tumor specific surface antigens in cancerous T cells. Therefore, our center plans to conduct a phase I clinical study of CAR-T to explore the possibility of bringing more treatment options and benefits to PTCL patients.

• Relapse or refractory peripheral T-cell lymphoma, which requires at least 2 systematic Sex therapy, is invalid or relapses.
• Histologically confirmed as CD7 positive.
• According to Lugano2014 standard, enhanced CT before enrollment should indicate at least one evaluable tumor lesion (with the longest diameter of the intranodal lesion\>1.5cm and the longest diameter of the extranodal lesion\>1.0cm), and PET/CT should show metabolic activity.
• Blood routine neutrophil count ≥ 1.0 during screening × 109/L; For individuals without bone marrow invasion, platelet count ≥ 75 × 109/L, Hb ≥ 80g/L; For individuals with bone marrow invasion, platelet count ≥ 50 × 109/L, Hb ≥ 60g/L (if the patient does not meet the screening requirements but meets the screening period requirements for re examination, they can be selected).

• Creatinine clearance rate\>60ml/min (Cockcroft and Gault formula); For patients without liver invasion, serum total bilirubin ≤ 1.5 times the upper limit of normal value, and serum ALT and AST ≤ 3 times the upper limit of normal value range; For patients with liver invasion, serum total bilirubin ≤ 3 times the upper limit of normal value, and serum ALT and AST ≤ 5 times the upper limit of normal value range.
• Echocardiography showed that left ventricular Ejection fraction (LVEF) ≥ 50%.
• Estimated survival time of over 3 months.
• ECOG: 0-1.
• Subjects or their Legal guardian voluntarily participate in the trial and sign the informed consent form.
• For patients undergoing reinfusion, in addition to meeting the relevant conditions for reinfusion in the Design of experiments, it is required that there is no DLT event or dose reduction after the first infusion.
• The first 6 subjects included at any dose level should be able to collect sufficient amounts of autologous hematopoietic stem cells for cryopreservation in advance; Subsequent subjects will be determined by the researcher whether to collect autologous hematopoietic stem cells for cryopreservation.

You may not qualify if:

• Primary cutaneous T-cell lymphoma, including mycosis fungoides (MF) and Sezary syndrome (SS); Enteropathy associated T-cell lymphoma (EATL), monotypic epitheliophagocytic intestinal T-cell lymphoma (MEITL), hepatosplenic T-cell lymphoma (HSTCL), extranodal NK/T-cell lymphoma, nasal type (EENKTCL) and primary central nervous system lymphoma and other types of T-cell leukemia/lymphoma.
• Active central nervous system (CNS) invasion.
• If anti-tumor treatment has been received before infusion, it should be excluded if any of the following conditions are met:
• received small molecule Targeted therapy within 72 hours
• Received systemic chemotherapy within 2 weeks (excluding pre-treatment)
• Received radiation therapy within 4 weeks
• When the time between the last monoclonal antibody infusion and those who have received monoclonal antibody treatment is less than 5 half-lives four weeks long or less (whichever is shorter)
• Individuals with a history of allergies to any component in cellular products.
• According to the New York Heart Association (NYHA) cardiac function grading standards, subjects with cardiac dysfunction classified as Class III or IV.
