Efficacy and Safety of CD19 CAR-γδ T Cells in the Treatment of Relapsed/Refractory Autoimmune Nephropathy
China15 participantsStarted 2026-05-01
Plain-language summary
This study is a single-arm, single-center, open-label, dose-escalation exploratory clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of CD19 CAR-γδ T cells. The subjects enrolled in this study are patients with relapsed/refractory autoimmune nephropathy, including lupus nephritis, IgA nephropathy, and membranous nephropathy. This study adopts a standard "3+3" design to assess the recommended dose (RD) and identify dose-limiting toxicities (DLTs). The treatment process is as follows: subjects who meet the inclusion criteria will receive lymphodepletion conditioning, followed by a single intravenous infusion of CD19 CAR-γδ T cells. The primary objective of this study is to evaluate the safety profile of this cellular therapy, including the incidence of DLTs, maximum tolerated dose (MTD) or RD, as well as the incidence and severity of treatment-related adverse events and clinically significant abnormal laboratory test results after CAR-γδ T cell infusion (including the incidence of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS)). The planned follow-up duration of this study is 1 years.

Inclusion criteria
. Age ≥18 years and ≤65 years;
. Agree to participate in this study and sign the informed consent form;
. Major organ function must meet the following criteria (exceptions are allowed for abnormalities associated with active autoimmune diseases):
. Liver function: ALT, AST or ALP level ≤3 × ULN (upper limit of normal), bilirubin ≤2 × ULN;
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Subjects with life-threatening conditions (e.g., catastrophic antiphospholipid syndrome, acute severe renal failure) assessed by the investigator as unsuitable for enrollment in this study;
. History of alcohol or drug abuse within 24 weeks prior to screening;
. History of malignant tumors other than B-cell lymphoma, except for the following: malignancies confirmed to be cured or in remission for ≥5 years, radically resected basal cell carcinoma or squamous cell carcinoma of the skin, and carcinoma in situ at any site;
. Major surgery (including joint surgery) within 24 weeks prior to screening, or planned surgery within 24 weeks after enrollment;
. Complicated with overlapping mixed connective tissue disease, or other diseases that affect the assessment of disease activity;
. Active hepatitis B or hepatitis C virus infection, defined as: subjects positive for hepatitis B surface antigen (HBsAg) and/or hepatitis B core antibody (HBcAb) with peripheral blood high-sensitivity HBV DNA quantification above the lower limit of detection; subjects with peripheral blood high-sensitivity HBV DNA quantification below the lower limit of detection may be enrolled only if the investigator provides appropriate prophylactic antiviral therapy; individuals positive for hepatitis C virus (HCV) antibody with positive peripheral blood high-sensitivity HCV RNA quantification;
. Coinfection with human immunodeficiency virus (HIV), human T-cell leukemia virus (HTLV), Treponema pallidum, cytomegalovirus (CMV), or complicated with selective IgA deficiency;
. Uncontrolled active infection (e.g., active pulmonary tuberculosis, etc., excluding simple urinary tract infection and bacterial pharyngitis); prophylactic administration of antibiotics, antiviral or antifungal agents is permitted;
