About this study

The study will evaluate safety and efficacy of a 4th generation chimeric antigen receptor gene-modified T cells targeting CD19 (4SCAR19) for patients with B cell malignancies. Clinical response and development of a standardized lentiviral vector and cell production protocol will be investigated. This is a phase I/II trial enrolling patients from multiple clinical centers.

Read the detailed description

Background:

T cells modified with lentiviral chimeric antigen receptor (CAR) gene have been studied in different clinical settings. Recent successes suggest that increased costimulatory signaling in the CAR design is critical for long term efficacy. Activation of T cell response from large tumor burden may induce a severe response. To increase safety, a novel design using an inducible caspase 9 fusion gene has been incorporated in the CAR gene. A 4th generation CAR lentiviral vector (4SCAR) carrying T cell costimulatory signals for CD28/CD27 plus an inducible apoptotic caspase 9 gene has been established. The study aims to evaluate the activities of a new CAR gene-modified T cells targeting CD19-positive tumors based on a CD19-specific single chain gene constructed 4SCAR (4SCAR19).

Objective:

To evaluate safety and efficacy of administrating 4SCAR19 T cells to patients with CD19 positive B cell malignancies following a cyclophosphamide/fludarabine based conditioning regimen.

Eligibility:

Patients older than 6-month-old with CD19 positive B cells malignancies that have recurred after or refractory to standard therapy and is deemed incurable using standard treatment.

Design:

Participants will be screened based on cancer cell phenotype analyzed using flow cytometry or immunohistochemical staining methods.

Peripheral blood mononuclear cells (PBMC) will be obtained through apheresis, and T cells will be activated and modified to express the 4SCAR19 gene.

On Day -5 to -7, PBMC will be activated and enriched for T cells, which will be followed by 4SCAR19 lentiviral transduction. The total cell preparation time is approximately 5-7 days.

Participants will receive a preparative conditioning regimen comprising cyclophosphamide/fludarabine to prepare their immune system to accommodate the modified CAR T cells. The preparative regimen will be based on patient immune condition and consistent with standard chemotherapy conditioning regimen.

Participants will receive an infusion of the modified 4SCAR19 T cells and closely followed up for treatment-related responses.

Participants will be continuously monitored for CAR T cells and clinical responses at present timeline.

Questions about this trial

What is this clinical trial studying?

A study testing Therapeutic 4SCAR19 cells in people with B-cell Malignancies, 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 5 inclusion and 7 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: stopped early, 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.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of fourth generation anti CD19 CAR-T cells in patients with relapsed B cell malignancies using CTCAE 4 standard to evaluate the level of adverse events (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03050190, which also lists 1 linked publication.

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.
