Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical trial is to learn if allogeneic, umbilical cord blood-derived chimeric antigen receptor T-cell (UCAR-T) targeting CD19 and BCMA works to treat refractory SLE in adults. It will also learn about the safety and efficacy of the UCAR-T cell product.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* The main questions it aims to answer are: What CAR-T-related adverse events (AEs) occur within 3 months after the UCAR-T cell infusion? Which dose level is the optimal biological dose (OBD)? What are the changes of disease activity status, proportion of patients achieving DORIS remission, percentage of participants achieving maintenance of drug-free DORIS remission, proportion of patients achieving SRI-4 remission, percentage of participants achieving maintenance of LLDAS?
* Participants will may receive lymphodepletion chemotherapy (fludarabine plus cyclophosphamide) if clinically needed. If lymphodepletion chemotherapy is administered, rest for 2 days on Day -2 and Day -1. Receive UCAR-T cells infusion on Day 0. Then be hospitalized for at least 7 days post-infusion for close safety monitoring and remain within 2 hours of the treatment facility for at least 28 days. Visit the clinic at Day 14, Day 28, month 3, month 6, month 9, month 12, month 18 and month 24 after UCAR-T cells infusion.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Aged 18 to 75 years (inclusive), regardless of gender.
* Definitive diagnosis of systemic lupus erythematosus (SLE) meeting the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for SLE
* Treatment refractory: failed ≥ 2 conventional SLE treatments for at least 3 months.
* Disease activity assessed by SELENA-SLEDAI score ≥ 6 with at least one British Isles Lupus Assessment Group (BILAG)-2004 Class A (severe manifestation) or two Class B (moderate manifestation) organ scores (or both); OR SELENA-SLEDAI score ≥ 8.
* Adequate function of major organs as follows:

Bone marrow function: a. Neutrophil count ≥ 1 × 10⁹/L (no colony-stimulating factor therapy within 2 weeks prior to testing, excluding neutropenia caused by SLE); b. Hemoglobin ≥ 60 g/L.

Liver function: Alanine aminotransferase (ALT) ≤ 3 × upper limit of normal (ULN) (excluding ALT elevation caused by SLE); Aspartate aminotransferase (AST) ≤ 3 × ULN (excluding AST elevation caused by SLE); Total bilirubin (TBIL) ≤ 1.5 × ULN (excluding TBIL elevation caused by SLE).

Renal function: Creatinine clearance rate (CrCl) ≥ 30 mL/minute (calculated by Cockcroft/Gault formula, excluding CrCl reduction caused by SLE).

Coagulation function: International normalized ratio (INR) ≤ 1.5 × ULN; Prothrombin time (PT) ≤ 1.5 × ULN.

Cardiac function: Hemodynamically stable.

* Female subjects of childbearing potential and male subjects whose partners are of childbearing potential must use medically approved contraceptive methods or abstain from sexual intercourse during the study treatment period and for at least 6 months after the end of study treatment. Female subjects of childbearing potential must have a negative serum human chorionic gonadotropin (HCG) test within 7 days prior to study enrollment and must not be breastfeeding.
* Voluntarily agrees to participate in the clinical study, signs the informed consent form (ICF), and demonstrates good compliance with study procedures and follow-up.

Exclusion Criteria

* History of severe drug allergies or atopic diathesis.
* Presence or suspicion of uncontrolled or treatment-requiring fungal, bacterial, viral, or other infections.
* Cardiac function insufficient to tolerate the study treatment.
* Congenital immunoglobulin deficiency.
* History of malignant tumors within the past 5 years.
* End-stage renal failure.
* Positive for hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (HBcAb) with peripheral blood HBV DNA titer above the lower limit of detection; positive for hepatitis C virus (HCV) antibody with positive peripheral blood HCV RNA; positive for human immunodeficiency virus (HIV) antibody; positive syphilis test.
* History of mental illness or severe cognitive impairment.
* Use of disease-modifying immunosuppressive agents within 5 half-lives or biological agents within 4 weeks prior to enrollment.
* Pregnant females or females planning to become pregnant.
* Other conditions deemed by the investigator to preclude study participation.
