Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This single-arm, multicenter clinical study will treat the patient who have relapsed or refractory neuroblastoma with an infusion of the patient's own T cells that have been genetically modified to express a chimeric antigen receptor(CAR)that will bind to tumour cells modified to express the GD2 protein on the cell surface. The study will determine if these modified T cells help the body's immune system eliminate tumour cells .The trial will also study the safety of treatment for CAR-T, how long CAR-T cells stay in the patient's body and the impact on this treatment for survival.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-arm, multicenter clinical study to evaluate efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) in the treatment of relapsed or refractory neuroblastoma in children. The study will be conducted using a phaseⅠ/Ⅱdesign the study will have the following sequential phases: part A (screening, leukapheresis,cell product preparation and cytoreductive chemotherapy) and part B (treatment and follow-up). the follow-up period for each participant is approximately 35 months after the final CAR-T infusion. The total duration of the study are expected to be approximately 3 years. A total of 22 patients may be enrolled over a period of 3 years.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Up to diagnostic criteria for relapsed or refractory neuroblastoma or high-risk patients,including:

* Relapsed neuroblastoma : Children diagnosed with neuroblastoma who after standard treatment and remission, present lesions again and cannot reach complete remission with surgery.
* Refractory neuroblastoma : ① Untreated patients that do not have to reach completes remission after 4 courses of chemotherapy in accordance with standard regimens nor reach complete remission with surgery. ② High-risk patients : Who have cell genetic variation, such as MYCN amplification or bone marrow metastasis.
2. Relapsed or Refractory Neuroblastoma: Target, of which expression may be intervened , discovered with Immunohistochemistry can be selected (GD2 +) (more than 50% of tumor cells is at least 2+ , adopting anti-GD2-mAb14G2a ).
