Early Clinical Study of UTAA09 Injection in the Treatment of Relapsed/Refractory
Main purpose: To evaluate the safety of UTAA09 injection in the treatment of relapsed/refractory (R/R) autoimmune disease (AID). Secondary purpose: 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.
∙ (3) Histological evidence of non-suppurative destructive cholangitis and small bile duct destruction.
∙ (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. If Gilbert syndrome is diagnosed, the total bilirubin index can be relaxed to ≤3.0×ULN and the direct bilirubin ≤1.5×ULN.
‣ (5) no serious mental disorders; (6) Can understand this test and have signed the informed consent.
