4. Confirmed diagnosis of primary AIHA or secondary autoimmune disease (except rheumatoid arthritis and systemic lupus erythematosus) with underlying disease in a stable state;

5. Poor response to at least previous glucocorticoid therapy, including ineffective (defined as failure to achieve stabilization of Hb levels at 100 g/L or erythrocyte hematocrit <30% despite at least 4 weeks of treatment with previously recommended doses), or glucocorticoid-dependent (defined as maintenance of equal doses of prednisone exceeding 15 mg/d), or relapsed (defined as treatment that is effective and then again has an Hb of <100 g/L or an erythrocyte hematocrit of <30%), or otherwise contraindicated. 30%), or otherwise contraindicated or intolerant to glucocorticoid therapy;

6. Hemoglobin (Hb) <100 g/L before drug administration;

7. Positive direct anti-human globulin test (DAT) (IgA, IgM or IgG+, with or without C3+).

8. Combination of one anti-AIHA therapy [glucocorticoids only (≤15 mg prednisone equivalent), immunosuppressants (azathioprine, cyclosporine, and merti-macrolide only)] is permitted in this study, provided that the dose has been stable for at least 28 days prior to enrollment;

9. Laboratory tests meet the following criteria (no treatment for the abnormality of the index within 2 weeks prior to blood collection, or no long-acting G-CSF treatment within 2 weeks)

1. Neutrophil count >1.5×109/L and platelet >30×109/L;

2. ALT and AST ≤ 2 × ULN;

3. Serum creatinine concentration ≤ 2 × ULN and creatinine clearance ≥ 50mL/min;

10. No active infection; no pregnancy or lactation;

11. cAIHA patients presenting with skin cyanosis and thrombosis;

12. Written evidence of Neisseria meningitidis and Streptococcus pneumoniae vaccinations within 2 years or, if none, antibiotic prophylaxis until 2 weeks after completion of vaccination.

2. Hb <100 g/L due to non-AIHA factors; and

3. Infections requiring systemic therapy;

4. Those with a past history of malignancy (except cured basal cell carcinoma of the skin or cervical carcinoma in situ);

5. With history of vital organ transplantation or hematopoietic stem cell/bone marrow transplantation;

6. Those who have undergone splenectomy within 24 weeks prior to enrollment;

7. Those who have had major surgery within four weeks prior to enrollment or who require major elective surgery during the study period;

8. History of severe cardiovascular disease [e.g., class III/IV congestive heart failure, arrhythmia or angina requiring medication, unstable angina, coronary stenting, angioplasty or coronary artery bypass grafting, or corrected Q-T interval (QTcF) ≥ 90 mmHg]

9. Patients with medically uncontrolled hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg); or comorbid portal hypertension;

10. Patients with severe gastrointestinal disorders such as dysphagia, active gastric ulcers, etc., who are unable to take drugs orally or have impaired absorption of oral drugs;

11. Human immunodeficiency virus (HIV) infection

12. Uncontrolled or active HBV infection [Hepatitis B surface antigen (HBsAg) or Hepatitis B core antibody (HBcAb) positive patients, need to confirm Hepatitis B Virus Deoxyribonucleic Acid (HBV DNA) positive]; or Hepatitis C [patients with Hepatitis C Virus Ribonucleic Acid (HCV RNA) positive patients]; or cirrhosis of the liver;

13. Those who had received herbal treatment within one week prior to enrollment that interfered with the assessment of efficacy;

14. Patients with severe psychological or psychiatric abnormalities;

15. Alcohol or drug abusers;

16. Female patients who are pregnant or breastfeeding;

17. Patients who, in the opinion of the investigator, are not suitable for participation in this study.
