• Platelets ≥ 50 × 109/L;d. Hemoglobin ≥ 80g/L
• Liver function:
• Alanine Aminotransferase (ALT) ≤ 3 × ULN;
• Asparagus cochinchinensis transase (AST) ≤ 3 × ULN;
• Total Bilirubin (TBIL) in serum ≤ 1.5 × ULN (excluding Gilbert syndrome, total bilirubin ≤ 3.0 × ULN); Renal function: Creatinine Clearance Rate (CrCl) ≥ 60 ml/minute (Cockcroft/Fault formula) ;

• Willing to participate in this clinical study, sign an ICF, and complete follow-ups, with good compliance.

You may not qualify if…

• Have a serious history of Drug allergy or allergic constitution;
• Fungi, bacteria, viruses, or other infections that are uncontrollable or require intravenous medication treatment exist or are suspected;
• Active central nervous system disease caused by SLE or not (including epilepsy, psychosis, organic encephalopathy syndrome, cerebrovascular accident, encephalitis, central nervous system Vasculitis);

• Corticosteroid (defined as prednisone or equivalent>20 mg/day) of therapeutic dose were used before enrollment or within 72 hours before BRL-301 infusion.
• Use any other clinical study drugs for SLE within 4 weeks prior to enrollment. However, if the research treatment period is ineffective or the disease progresses, and at least 3 half-lives have passed before enrollment, enrollment is allowed.
• Had received anti CD20 monoclonal antibody (such as Rituximab) within 4 weeks before screening, tetaximab within 6 weeks, or belizumab within 12 weeks.
• Previous CAR-T cell or other genetically modified T Cell therapy.
• Subjects with positive hepatitis B B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and HBV DNA titer in peripheral blood higher than the upper limit of detection; Patients with positive hepatitis C virus (HCV) antibodies and positive peripheral blood HCV RNA; People who are positive for human immunodeficiency virus (HIV) antibodies; Those who have tested positive for syphilis;
• Having mental illness and severe cognitive impairment;
• Those who have participated in other clinical trials within the first 3 months of enrollment;
