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 Autoimmune Hemolytic Anemia
This is an open label, single-site, dose-escalation study in up to 18 participants with relapsed or refractory Autoimmune hemolytic anemia. 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 Autoimmune hemolytic anemia.
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.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing UCAR T-cell group in people with Relapsed / Refractory Autoimmune Hemolytic Anemia, run by Zhejiang University.
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 11 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 9 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
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?
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?
The number and severity of dose-limiting toxicity (DLT) events (time frame: Within 28 Days After UCAR T-cell Infusion). The study lists 3 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 9 Apr 2025.
