About this study
Official title: Multicenter Trial of Phase I/II Studies on CD276 (B7-H3) Positive Solid Tumors Treated With 4SCAR-276
Patients with refractory and/or recurrent solid tumor have poor prognosis despite complex multimodel therapy and therefore, novel approaches are urgently needed. This study attempts to treat these diseases using T cells genetically modified with a 4th generation lentiviral chimeric antigen receptor (4SCAR fused with an inducible apoptotic caspase 9 domain) targeting CD276 (B7-H3). The 4SCAR-CD276-modified T cells (4SCAR-276) can recognize and kill tumor cells through the recognition of CD276, a surface protein expressed at high levels on many types of tumors but at low levels on normal tissues. This study will evaluate the side effects and effective doses of 4SCAR-276 in treating refractory and/or recurrent tumors.

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.
Background: Patients with refractory and/or recurrent solid tumors have poor prognosis despite complex multimodal therapy; therefore, novel curative approaches are needed. The investigators are attempting to use T cells obtained directly from the patient, which can be genetically modified to express a 4th generation CD276-specific chimeric antigen receptor (4SCAR-276). The CAR molecules enable the T cells to recognize and kill tumor cells through the recognition of the surface CD276, which is expressed at high levels on tumor cells including brain tumors, Ewing's sarcoma (PNET) and many other tumors but not at significant levels on normal tissues. This study will evaluate the side effects and the best dose of a novel 4th generation anti-CD276 CAR T cells to target refractory and/or recurrent solid tumors.
Design:
- Participants will be screened through physical exam and medical history. Blood and tumor tissue samples will be collected. Imaging studies will be performed.
- Peripheral blood mononuclear cells (PBMC) will be obtained by apheresis, and T cells will be activated and modified to express the 4SCAR-276 gene.
- On Day -5 to -7, PBMC will be activated and enriched for T cells, which will be followed by 4SCAR-276 lentiviral transduction. The total culture time is approximately 5-7 days.
- Participants will receive a preparative conditioning regimen comprising cyclophosphamide/fludarabine to prepare their immune system to accept the modified CAR T cells. The preparative regimen will be based on patient immune condition and consistent with standard chemotherapy conditioning regimen.
- The patients will receive ~10^6 CART cells/kg body weight per infusion, and may receive additional booster CART infusions if positive outcome is recorded.

A Phase 1/2 study testing 4SCAR-276 in people with Solid Tumor, 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 14 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 2 Nov 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, Ph.D (+86-13671121909, 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 years). 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 2 Nov 2026.
