Neuroblastoma (NB) is a malignant tumor of the sympathetic nervous system.Chemotherapy and autologous hematopoietic stem cell transplantation are the main treatments for neuroblastoma, and the prognosis of patients with high-risk recurrence and refractory treatment is very poor. There is a large unmet medical need in patients with relapsed refractory neuroblastoma, and further research into new therapeutic approaches is needed for these patients.GD2 is a dissialic ganglioside expressed by neuroectodermal tumors. The proportion of GD2 expression in neuroblastoma is up to 100%, so GD2 is a specific target for neuroblastoma immunotherapy and an ideal target for CAR-T treatment of neuroblastoma.
All cases were diagnosed as neuroblastoma with positive expression of GD2 antigen in tumor cells. Informed consent of patient or guardian.
Diagnosis of recurrent/refractory neuroblastoma.
At least 2 weeks or 5 half-lives (whichever is shorter) from the beginning of preconditioning chemotherapy after prior systemic treatment.
Toxic reactions caused by previous antitumor therapy must be stabilized and restored to ≤ grade 1.
The subject has had other malignancies, non-melanoma skin tumors, carcinoma in situ (e.g. Cervix, bladder, breast), unless disease-free survival of at least 3 years.
There is an uncontrollable infection, including fungal, bacterial, viral or other.
Known human immunodeficiency virus (HIV) infection.
Known history of hepatitis B (HBsAg positive) or hepatitis C (HCV antibody positive). Subjects with latent or prehepatitis B infection (defined as HBcAb positive and HBsAg negative) can be enrolled only if PCR tests for HBV DNA are negative. In addition, these subjects were required to undergo a monthly PCR test for HBV DNA. Participants who are serologically positive for HCV antibodies can also be enrolled if their PCR test results for HCV RNA are negative.
