1. According to the revised 2024 McDonald diagnostic criteria, they are clinically diagnosed with progressive MS (including primary progressive PPMS or secondary progressive SPMS) or relapsing-remitting MS (RRMS), and their disability status at the time of screening meets an EDSS score of 2-7 (inclusive).
2. For RRMS patients, they need to meet any of the following conditions: a) They have failed treatment with ≥1 effective DMT (fenogomide, cinemodide, ozamod, and anti-CD20 monoclonal antibody therapy, etc.); b) They have had at least 2 clinical relapses in the past 2 years, or they have had 1 clinical relapse in the past 2 years and MRI shows ≥1 new Gd-enhanced lesion, or they have had ≥1 new Gd-enhanced lesion on MRI within the past 6 months; c) There are ≥2 active Gd-enhanced lesions on T1-weighted brain MRI at the time of screening.
3\. The functions of important organs should meet the following requirements:
1. Bone marrow function should satisfy: a. Neutrophil count ≥ 1×109/L (no colony-stimulating factor treatment within 2 weeks before the examination, and neutrophil reduction caused by the disease is excluded); b. Hemoglobin ≥ 60g/L;
2. Liver function: ALT ≤ 3×ULN (ALT elevation caused by the disease can be excluded); AST ≤ 3×ULN (AST elevation caused by the disease can be excluded); TBIL ≤ 1.5×ULN (TBIL elevation caused by the disease can be excluded);
3. Kidney function: Creatinine clearance rate (CrCl) ≥ 30 ml/minute (Cockcroft/Gault formula, acute CrCl decline caused by the disease is excluded);
4. Coagulation function: International normalized ratio (INR) ≤ 1.5×ULN, prothrombin time (PT) ≤ 1.5×ULN;
5. Cardiac function: Good hemodynamic stability;
4\. For female subjects with reproductive capacity and their male partners, as well as male subjects whose female partners are of childbearing age, they are required to adopt medically approved contraceptive measures or abstain from sexual activity during the study treatment period and for at least 12 months after the end of the study treatment; female subjects of childbearing age must have a negative serum HCG test result within 7 days before study enrollment and must not be in the lactation period.
5\. Voluntarily participated in this clinical study, signed the informed consent form, had good compliance, and cooperated with the follow-up.
