Prothrombin time (PT) ≤1.5×ULN; Cardiac function: Hemodynamic stability with left ventricular ejection fraction (LVEF) ≥55%.

7. Agrees to use double barrier methods, condoms, oral or injectable contraceptives, or intrauterine devices during the study period and for one year after taking the study medication. Females of childbearing potential must have a negative serum HCG test within 7 days prior to enrollment and must not be lactating.

8. Voluntarily participate in the study, provide written informed consent, and demonstrate good compliance with follow-up.

Exclusion Criteria

4. Active or suspected uncontrolled infections requiring treatment (including fungal, bacterial, viral, or other pathogens).

5. Central nervous system disorders caused by autoimmune diseases (ADs) or non-ADs.

6. Severe cardiac diseases.

7. Congenital immunoglobulin deficiency.

8. History of malignancy (except non-melanoma skin cancer, in situ cervical/bladder/breast/thyroid carcinoma with disease-free survival >5 years).

9. End-stage renal failure.
