However, due to the absence of a curative treatment, patients typically need to remain on medication indefinitely. In recent years, biological agents such as belimumab and rituximab have been introduced for the treatment of SLE, but these treatments cannot completely eliminate autoimmune B cells in the bone marrow, leading to unsatisfactory overall outcomes. Furthermore, discontinuing these drugs can lead to disease relapse, and there is still no cure for SLE, leaving patients facing the challenges of lifelong medication and an incurable disease.\n\nCAR-T therapy is an adoptive cell therapy that uses genetic modification technology to reprogram T cells and eliminate target cells expressing disease-related antigens through antigen-specific recognition. Since 2019, CAR-T cell therapy has been successfully applied to autoimmune diseases. Clinical studies have demonstrated that CD19-targeted CAR-T cells hold significant therapeutic potential for SLE. Compared with traditional CAR-T cells, ultra-fast CAR-T, relying on an innovative CAR-T manufacturing system, can produce CAR-T cells in an extremely short period of time (with a preparation time of only 10 minutes).\n\nThe purpose of this study is to assess the safety and efficacy of the ultra-fast autologous CD19-targeted CAR-T cells in the treatment of refractory SLE.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age ≥ 18 years old;\n* Diagnosed with SLE according to the 2019 EULAR/ACR SLE classification criteria, and still in moderate to severe disease activity despite ≥3M of high dose glucocorticoids(prednisone≥1mg/kg/d or other equivalent amount of other steriod), and/or hydroxychloroquine, and at least 2 DMARDs(include cyclophosphamide, mycophenolate mofetil, azathioprine, methotrexate, cyclosporin, tacrolimus, sirolimus, leflunomide, telitacicept, beliumab, and rituximab) or intolerant to standard treatments;\n* SLEDAI-2K score ≥ 8 points;\n* Meet the standards of leukapheresis or intravenous blood collection, and no contraindication for leukapheresis;\n* Negative pregnancy test for female subjects of childbearing age, and agree to take effective contraceptive measures until one year after CAR-T infusion;\n* Participant or his/her guardians agree to participate in the clinical trial and sign the informed consent form which indicating that he/she understands the purpose and procedure of the clinical trial and is willing to participate in the study.\n\nExclusion Criteria:\n\n* Central nervous system (CNS) disease: CNS neurolupus requires intervention within 30 days;\n* Have a history of congenital heart disease or acute myocardial infarction within 6 months prior to screening or severe arrhythmias (including multisource frequent supraventricular tachycardia, ventricular tachycardia, etc.);
