Brief Summary

This is an open-label, Phase I, investigator-initiated trial (IIT) aimed at evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD06-04 in patients with autoimmune diseases mediated by autoantibodies. The study population includes patients with Systemic Lupus Erythematosus (SLE), Systemic Sclerosis (SSc), ANCA-Associated Vasculitis (AAV), Idiopathic Inflammatory Myopathy (IIM), Sjögren's Syndrome (SS), Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorder (NMOSD), and Myasthenia Gravis (MG).

Eligibility Criteria

• Age: 18 Years - 70 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• The subjects voluntarily participated in the study and signed the informed consent form.
• Age ≥18 years old and ≤70 years old, both sexes.
• Organ function and laboratory tests:
• 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.
• Blood routine: neutrophil count ≥1×109/L, hemoglobin ≥60g/L, platelet count ≥20×109/L, lymphocyte count \>0.3×109/L.
• Coagulation: international normalized ratio (INR) ≤ 1.5×ULN, or prothrombin time (PT) ≤ 1.5×ULN.
• Oxygen saturation (SpO2) ≥92% at rest in room air.
• Left ventricular ejection fraction (LVEF) ≥50% on echocardiography.
• Negative serum or urine pregnancy test results in female subjects of childbearing potential at screening.
• Women of childbearing potential must agree to use a highly effective method of contraception for at least 28 days before initiation of elution and up to 12 months after RD06-04 reinfusion. Men of childbearing potential had to agree to the use of an effective barrier method of contraception from the initiation of lymphoidectomy until 12 months after reinfusion of RD06-04 and had to refrain from donating semen or sperm throughout the trial.
• A definitive diagnosis of SLE according to the 2019 European League Against Rheumatism (EULAR) / American College of Rheumatology (ACR) classification criteria or the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria.
• Positive antinuclear antibodies (ANA) at screening, and/or positive anti-double-stranded DNA (anti-dsDNA) antibodies, and/or positive anti-Smith antibodies.
• A SLEDAI-2K score \>6 at screening, and a 'clinical' SLEDAI-2K score ≥4.
• Diagnosed with SSc according to the 2013 ACR/EULAR classification criteria.

You may not qualify if:

• 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.
• MG Patients: Presence of uncontrolled myasthenia gravis crisis within 2 weeks prior to 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.
• Positive for hepatitis B surface antigen (HBsAg), or positive for hepatitis B core antibody (HBcAb) with detectable hepatitis B virus (HBV) DNA in peripheral blood; positive for hepatitis C virus (HCV) antibody with detectable HCV RNA in peripheral blood; positive for human immunodeficiency virus (HIV) antibody; positive for syphilis antibody.
• Pregnant or breastfeeding women.
• Any condition that, in the investigator's opinion, may affect study participation, pose a safety risk to the patient, or potentially confound the interpretation of study results.
