Brief Summary

To evaluate the safety of UTAA09 injection in the treatment of relapsed/refractory (R/R) autoimmune disease (AID).

To evaluate the pharmacokinetic (PK) profile of UTAA09 injection in patients with R/R AID.

To evaluate the pharmacodynamic (PD) characteristics of UTAA09 injection in patients with R/R AID.

To evaluate the initial efficacy of UTAA09 injection in the treatment of R/R AID subjects.

To evaluate the immunogenicity of UTAA09 injection in R/R AID subjects.

Detailed Description

This clinical trial was designed as a single-arm, open-label, single-center, investigator-initiated early-stage clinical study to evaluate the safety of UTAA09 injection in patients with relapsed/refractory AID. After signing the informed consent letter, qualified subjects were screened for infusion of UTAA09 injection, and their blood was collected before and after infusion for pharmacokinetics, pharmacodynamics, immunogenicity, safety and other evaluation. In addition to the baseline period, therapeutic efficacy was evaluated at a frequency of 28d, 2m, 3m, 4m, 5m, 6m, 8m, 10m, 12m after cell transfusion, and tumors were evaluated until disease progression (PD), new anti-disease therapy, death, intolerable toxicity, investigator decision, or subject's voluntary withdrawal, whichever occurred first.

All adverse events were recorded from the beginning of the subject's elutriation pre-treatment (if it occurred) until 3 months after the subject received cell transfusion or disease progression/recurrence or initiation of a new anti-disease therapy or the end of the study, whichever occurred first, and 3 months after cell transfusion or disease progression/recurrence or initiation of a new anti-disease therapy (whichever occurred first) until the end of the study. Only adverse events associated with the study product were collected

Group Type: OTHER

T cell injection targeting CD19 chimeric antigen receptor

Intervention Type: BIOLOGICAL

Intravenous administration, 1 bag each time (depending on individual differences), dose: 1×108-1×109 CD19-CAR-gdT (UTAA09 injection), the investigator can decide whether to reduce or increase the dose and whether multiple infusions are required according to the condition of the subject.

Eligibility Criteria

Inclusion Criteria

(2) Expected survival time ≥3 months; (3) Subjects with recurrent/refractory autoimmune disease who have failed standard treatment or lack effective treatment, including but not limited to systemic lupus erythematosus, idiopathic inflammatory myopathy, systemic sclerosis, Sjogren's syndrome, rheumatoid arthritis, connective tissue disease-associated interstitial lung disease, immune thrombocytopenia, primary biliary cholangitis, etc.

(4) Liver and kidney function, cardiopulmonary function meet the following requirements:

• Creatinine ≤1.5×ULN; (2) Electrocardiogram showed no clinically significant abnormal bands;

• Blood oxygen saturation >91% in non-oxygen state;

• Total bilirubin ≤2×ULN; ALT and AST≤2.5 x ULN; ALT and AST abnormalities due to disease, such as liver infiltration or bile duct obstruction, were determined to be less than 5×ULN.
