About this study
Official title: An Investigator-initiated Trial to Evaluate the Efficacy and Safety of Anti-CD19 Universal CAR-T Cells in the Treatment of Relapsed/Refractory(r/r) CD19+ B-cell Acute Lymphoblastic Leukemia(B-ALL)
This is a single-arm, single-center, open-labeled clinical study to evaluate the safety and efficacy of UCAR-T Cells injection for patients with relapsed/refractory(r/r) B-cell Acute Lymphoblastic Leukemia(B-ALL).
Read the detailed description
Although the anti-CD19 CAR-T cell therapies have gained significant clinical outcome in patients with r/r B-ALL，autologous CAR-T is not feasible for some patients. To make further improvement, the investigators are going to conduct a clinical trial using universal CAR-T(UCAR-T) cells targeting CD19 for r/r B-ALL patients.
After enrollment, patients will get a 3-5 days lymphodepletion therapy, then the UCAR-T Cells will be infused by vein. Subjects will be followed for safety and efficacy up to 12 weeks. For those with a durable remission 12 weeks after infusion, the follow-up will last for at least 12 months for disease control.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UCAR-T CellsBiological
UCAR-T Cellswill be administered by vein. The trial includes two portions. The first portion is a"3+3"dose escalation study, in which three dose groups are set:Dose level one:1×10^6 cells/kg;Dose level two:2×10^6 cells/kg;Dose level three:5×10^6 cells/kg. Each dose group requires at least three subjects. The trial will start from dose level one. The second portion includes a dosage extended cohort and will start after the finish of the"3+3"dose escalation study. Twelve subjects will get infusion of UCAR-T Cells at the best dose verified in the first portion.
| Study group | Role | What they receive |
|---|---|---|
| Assigned Interventions | Experimental | Subjects who meet the enrollment conditions will receive intravenous infusion of UCAR-T Cells after lymphodepletion. Receives: Biological: UCAR-T Cells |

Measured: Up to 24 weeks after infusion
Objective response rate (ORR)
Patients who achieve CR(complete response) or CRi after infusion

Progression-free survival (PFS)
Progression-free survival (PFS) is the time between the time a patient with tumor disease receives treatment and the time between the observation of disease progression or death from any cause.
Measured: Up to 24 weeks after infusion
Overall survival (OS)
Overall survival (OS) is the time from randomization to death from any cause.
Measured: Up to 24 weeks after infusion
Duration of remission (DOR)
Duration of remission (DOR) is the time from the first detection of CR or PR to the discovery of PD.
Measured: Up to 24 weeks after infusion

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing UCAR-T Cells in people with B-cell Acute Lymphoblastic Leukemia and B-ALL, run by 920th Hospital of Joint Logistics Support Force of People's Liberation Army of China 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 9 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 8 Dec 2022. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Wang Sanbin, Doctor (13187424131 ext. +86, Sanbin1011@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-limiting toxicity (DLT) (time frame: Up to 28 days after infusion). The study lists 2 primary outcomes in all. 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 8 Dec 2022; AzTrials last refreshed its copy on 8 Nov 2026.
