This is an open clinical pharmacological translational Research Study, aiming to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of CD19 or CD19-BCMA CAR-T in patients with active SLE, SSc, AAV, IIM and pSS.
The subjects voluntarily participated in the study and signed the informed consent form.
Age ≥18 years old and ≤70 years old, both sexes.
Liver function: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3× upper limit of normal (ULN), total bilirubin (TBIL) ≤2×ULN (except Gilbert's syndrome).
Renal function: creatinine ≤1.5×ULN or creatinine clearance ≥40 ml/min.
SLE Patients: Those with uncontrolled lupus crisis within the 8 weeks prior to screening, including rapidly progressive lupus nephritis, severe neuropsychiatric lupus, severe hemolytic anemia, severe immune thrombocytopenia, agranulocytosis, severe cardiac damage, severe lupus pneumonia, severe lupus hepatitis, and severe vasculitis, as assessed by the investigator as unsuitable to participate in this study.
IIM Patients: Presence of severe rhabdomyolysis or CK levels ≥120×ULN at screening.
Patients with severe asthma or Chronic Obstructive Pulmonary Disease (COPD) are eligible. Patients with mild or moderate asthma or COPD who are receiving stable treatment can also be enrolled.
There has been an active infection requiring systemic treatment within 2 weeks prior to the urethral irrigation, such as infectious pneumonia, tuberculosis, etc.
