• Must have been treated with glucocorticoids in combination with immunosuppressants and/or biologics for at least 2 months prior to screening and have been dose stable for >2 weeks, with the disease remaining active (i.e., prior glucocorticoid + immunosuppressant or glucocorticoid + immunosuppressant + biologics, any of the above medications alone do not qualify). Oral corticosteroids must meet the following requirements: 1) Prednisone (or equivalent) ≥ 7.5 mg/day; 2) When used in combination with immunosuppressants and/or biologics, there is no minimum daily dose requirement for corticosteroids.
• positive anti-nuclear antibody (ANA), and/or positive anti-ds-DNA antibody, and/or positive anti-Smith antibody at screening.
• Screening Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score >6 and 'clinical' SLEDAI-2K score ≥4.
• Note: 'Clinical' SLEDAI-2K is a SLEDAI-2K score that excludes scores attributable to any urine or laboratory findings, including immunological indicators: 2)-Includes scores for the following clinical items: arthritis, myositis, rash, alopecia, mucosal ulcers, pleurisy, pericarditis, or vasculitis; 3)-excludes scores attributable to fever, SLE headache and organic brain syndromes.
• British Isles Lupus Assessment Group 2004 (BILAG2004) score of at least one of the following:
• ≥1 organ system BILAG2004 grade A disease
• ≥2 organ system BILAG2004 Grade B disorders 6.Physician's General Assessment (PGA) score of ≥1.0 (0-3 visual analogue scale VAS) at screening.

You may not qualify if…

• Combination of other autoimmune diseases requiring systemic therapy.
• SLE patients: the presence of still uncontrolled lupus crisis within 8 weeks prior to screening, including acute progressive lupus nephritis, severe neuropsychiatric lupus, severe haemolytic anaemia, severe immune thrombocytopenia, granulocyte deficiency, severe cardiac damage, severe lupus pneumonitis, severe lupus hepatitis, severe vasculitis, etc., which were assessed as unsuitable for participation in the study by the investigator.
• Pre-screening comorbidity with clinically significant central nervous system disease or pathological changes not due to lupus, including but not limited to: cerebral vascular accident, aneurysm, epilepsy, convulsions/convulsions, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, organic brain syndromes, or psychosis.
• History of allogeneic bone marrow or stem cell transplantation or solid organ transplantation (e.g., kidney, lung, heart, liver) or future plans for such transplantation.
• Presence of clinically significant cardiovascular dysfunction in the 12 months prior to screening, including, but not limited to: class III or IV heart failure as defined by the New York Heart Association (NYHA), myocardial infarction, unstable angina pectoris, uncontrolled or symptomatic atrial arrhythmia, any ventricular arrhythmia.
• Presence of significant pulmonary or cardiac manifestations such as pericarditis, pleural effusion at the time of screening, assessed by the investigator to be unsuitable for participation in this study.
• Patients with severe asthma or chronic obstructive pulmonary disease (COPD), mild or moderate asthma or COPD on stable therapy may be enrolled.
• History of malignancy within 5 years prior to signing the Informed Consent Form (ICF), except adequately treated or surgically resected, non-melanoma skin cancers or carcinoma in situ (e.g., cervical cancer, bladder cancer, breast cancer) without residual disease.
• Women who are pregnant or breastfeeding.
• History of recurrent infections requiring hospitalisation and intravenous antibiotics (e.g. 3 or more episodes of the same type of infection in the past 1 year).
• Active infection requiring systemic treatment, such as infectious pneumonia, tuberculosis, etc., within 2 weeks prior to clearance.
• Hepatitis B surface antigen (HBsAg) positive, or Hepatitis B core antibody (HBcAb) positive and peripheral blood Hepatitis B Virus (HBV) DNA test positive; Hepatitis C Virus (HCV) antibody positive and peripheral blood HCV RNA positive; human immunodeficiency virus (HIV) antibody positive; syphilis antibody positive.
• Have received a live attenuated vaccine within 4 weeks prior to clearance or plan to receive a live attenuated vaccine during the course of the study.
• Have received high-dose corticosteroids (prednisone ≥ 60 mg/day or equivalent) within 4 weeks prior to clearance, or are unable to taper prednisone to ≤ 10 mg/day 5 days prior to clearance.
• Inability to taper or elute background therapy prior to clearing chemotherapy as described in Table 3.
• Receiving renal replacement therapy within 3 months prior to screening or anticipating the need for renal replacement therapy during the study.
• History of drug or alcohol abuse within 1 year prior to screening.
• History or evidence of suicidal thoughts within 6 months prior to screening or any suicidal behaviour within the previous 12 months that the investigator considers to be a significant risk of suicide.
• Use of another study drug within 4 weeks or 5 half-lives (whichever is longer) prior to screening.
• History of hypersensitivity or life-threatening reaction to the study drug or any component or preparation of the study treatment (including clear chemotherapy). See the Investigator's Brochure (IB) for more information about the components of the study drug.
• Any condition that, in the opinion of the investigator, may affect participation in the study, pose a safety risk to patients, or may confound the interpretation of study results.
