What is being measured
The primary outcome is the main question the study is designed to answer.
To evaluate the safety of CAR-T cells in relapsed/refractory neuroblastoma and desmoplastic small round cell tumor patients.
- To evaluate the safety of the infusion of CAR T cells at different escalating/deescalating doses and establish the dose limiting toxicity (DLT) of the cellular product. Toxicity will be evaluated according to the CTC AE scale, version 4.0. DLT will be defined as any of the following that is not pre-existing, due to infection or to underlying malignancy and that may be considered possibly, probably or definitely related to the study cellular products. (1) Non-hematologic DLT is any grade 3 or 4 non-hematologic toxicity; (2) Hematologic DLT is defined as any grade 4 hematologic toxicity related to infusion ; (3) Grade 4 reactions related to infusion; (4) Death related to CAR T cells infusions. The incidence of grade 3-5 toxicities, with a main attention to severe Cytokine Release Syndrome (CRS), will be evaluated.
- To determine the optimal dose of CAR transduced T cells resulting in the control of the disease without inducing unacceptable levels of toxicity (MTD) .
Measured: From enrollment to the end of treatment at 1 year
Secondary outcomes (1)
To evaluate the efficacy of CAR-T cells in relapsed/refractory neuroblastoma and desmoplastic small round cell tumor patients.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing CART therapy in people with Neuroblastoma (NB) and Desmoplastic Small Round Cell Tumor (DSRCT), run by Sun Yat-Sen University Cancer Center at 3 sites 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 14 inclusion and 17 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: looking for participants now, as of the sponsor's last update on 26 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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 Yizhuo Zhang, PhD (020-87342460, zhangyzh@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To evaluate the safety of CAR-T cells in relapsed/refractory neuroblastoma and desmoplastic small round cell tumor patients. (time frame: From enrollment to the end of treatment at 1 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 26 Feb 2025.
