About this study
Official title: Multi-center Phase I/II Clinical Trial of 4SCAR-T Therapy Targeting GD2, PSMA and CD276 for Treating Neuroblastoma
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.

Important Regulatory Notice:
This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.
ClinicalTrials.gov registration alone does not represent legal approval by Chinese health and drug regulatory authorities.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing GD2, PSMA and CD276 CAR-T cells in people with Neuroblastoma, run by Shenzhen Geno-Immune Medical Institute at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lung-Ji Chang, PhD (+86 0755-86573763, c@mkgimi.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with adverse events (time frame: 3 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2026.
