About this study
Official title: A Clinical Study Evaluating the Safety and Preliminary Efficacy of Universal Allogeneic CAR T-cell Therapy Targeting CD19 and BCMA in Patients With Relapsed / Refractory Myasthenia Gravis
This is an open label, single-site, dose-escalation study in up to 18 participants with relapsed or refractory Myasthenia gravis. This study aims to evaluate the safety and efficacy of the treatment with universal CD19/BCMA CAR T-cells.
Read the detailed description
This is an investigator-initiated trial to evaluate the safety and efficacy of universal CD19/BCMA CAR T-cells in Relapsed or Refractory Myasthenia gravis.
Study intervention consists of a single infusion of universal CAR T-cells administered intravenously after a lymphodepleting therapy regimen consisting of fludarabine and cyclophosphamide.
Interim analysis will be performed when participants finish the visit 90 days after CAR T-cell infusion.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UCAR T-cell groupBiological
A single injection of UCAR T-cells, referred to as universal allogeneic anti-CD19/BCMA CAR T-cells
| Study group | Role | What they receive |
|---|---|---|
| anti-CD19/BCMA CAR T-cells | Experimental | Universal allogeneic CD19/BCMA CAR T-cells Receives: Biological: UCAR T-cell group |
What is being measured
The primary outcome is the main question the study is designed to answer.
The number and severity of dose-limiting toxicity (DLT) events
DLT will be graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0, and the ASTCT Consensus Grading for Cytokine Release Syndrome and Neurologic Toxicity Associated with Immune Effector Cells.
Measured: Within 28 Days After UCAR T-cell Infusion
The total number, incidence, and severity of AEs
Measured: Up to 90 days After UCAR T-cell Infusion
Changes of Myasthenia Gravis Activities if Daily Living (MG-ADL) Score
MG-ADL scale assesses the impact of gMG on daily functions by measuring 8 signs or symptoms that are commonly affected in MG. Each item is measured on a 4-point scale, where a score of 0 represents normal function and a score of 3 represents the loss of ability to perform that function. Total scores range from 0 to 24 points, with a higher score showing more severe MG.
Measured: Up to 24 Months After UCAR T-cell Infusion
Quantitative Myasthenia Gravis Score (QMG)
The QMG score is a 13-item scale used to quantify disease severity in myasthenia gravis. The scale measures ocular, bulbar, respiratory, and limb function, grading each finding, and ranges from 0 (no myasthenic findings) to 39 (maximal myasthenic deficits).
Measured: Up to 24 Months After UCAR T-cell Infusion

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing UCAR T-cell group in people with Myasthenia Gravis, run by Zhejiang University 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 10 inclusion and 13 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 18 Apr 2025. 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 phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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 He Huang (86-13605714822, hehuangyu@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number and severity of dose-limiting toxicity (DLT) events (time frame: Within 28 Days After UCAR T-cell Infusion). The study lists 4 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 18 Apr 2025.
