Brief Summary:
The purpose of this clinical trial is to assess the feasibility, safety and efficacy of multiple 4SCAR-T cell therapy which targets GD2, PSMA and CD276 surface antigens in patients with relapsed and refractory neuroblastoma (NB). Another goal of the study is to understand the function of the multi-CAR-T cells and their persistency in the patients.

Condition or disease Intervention/treatment Phase
Neuroblastoma Biological: GD2, PSMA and CD276 CAR-T cells Phase 1 Phase 2

Detailed Description:

Neuroblastoma is one of the most aggressive childhood tumors arising from neural crest cells. Nearly 50% of patients with high risk disease have poor long-term survival even after multimodal treatments. Novel immunotherapy targeting tumor-specific antigens has been developed to meet the desperate need.

Disialoganglioside (GD2) is a well-studied tumor associated antigen which is expressed uniformly in NB but restrictedly in normal tissue. Over the past few years, CAR-T therapy against GD2 in NB has achieved encouraging but modest outcomes. Only a fraction of patients achieved measurable responses. Like for many other solid tumors, CAR-T therapy for NB is not as effective as for hematologic malignancies.

In this study, the investigators use "multiple targeting" approach as the strategy to overcome the challenge in treating NB. Prostate-specific membrane antigen (PSMA) is expressed in normal prostate but is upregulated in prostate tumor. However, PSMA expression is not restricted to prostate cancer. By immunohistochemistry (IHC) staining, the investigators confirmed that PSMA is expressed in a variety of solid tumors, including brain tumor, neuroblastoma and some lymphoma tumor tissues. Therefore, PSMA could potentially serve as a promising target for antigen-specific immunotherapy in patients with NB. In addition, CD276 (B7-H3) is an immune checkpoint molecule highly expressed on many solid tumors including NB. CD276 has been characterized to be involved in tumor evasion and thus its expression is correlated with poor prognosis. These characteristics make CD276 an attractive candidate for immunotherapy. Given the significant variation of tumor antigen expression among patients, the investigators aim to examine GD2, PSMA and CD276 expression in each patient's tumor sections by IHC staining, and combine two or three highly-expressed targets for the 4SCAR-T therapy. This individualized and multi-antigen-targeted approach is a new strategy to overcome the limited clinical outcome in the 4SCAR-T therapy against NB.

The purpose of this clinical study is to assess the feasibility, safety and efficacy of the combinational GD2, PSMA and CD276 4SCAR-T cell therapy against NB. Another goal of the study is to learn more about the function of the multi-4SCAR-T cells and their persistency in the patients.
