You may qualify if…

• 1. The laboratory test results at screening must meet the following criteria:
• a)Absolute neutrophil count ≥ 1.0 × 10\^9/L (no growth factor is given for supportive care within 7 days prior to testing);
• b)Absolute lymphocyte count ≥0.5×10\^9/L;
• c)Hemoglobin ≥ 80 g/L (no red blood cell transfusion is given within 7 days prior to testing);

• e)Serum IgG ≥ 500 mg/dL;
• f)Activated partial thromboplastin time ≤ 1.5 × upper limit of normal (ULN), prothrombin time (PT) ≤ 1.5 × ULN;
• g)Adequate renal, hepatic, cardiopulmonary function : i.Serum alanine aminotransferase and aspartate aminotransferase ≤ 3 × ULN; ii.Total bilirubin < 2 × ULN (direct bilirubin ≤ 1.5 × ULN for subjects with Gilbert's syndrome); iii.Trial participants with left ventricular ejection fraction ≥ 45% (performed within 8 weeks prior to apheresis) as diagnosed by echocardiography (ECHO) or multi-gated acquisition scan and no evidence of pericardial effusion as determined by ECHO and no clinically significant electrocardiographic findings; iv.Oxygen saturation > 92% under indoor air conditions; v.Estimated glomerular filtration rate ≥ 60 mL/min/1.73 m\^2.(CKD-EPI 2021 Formula).
• 2.Confirmed diagnosis of MS based on the 2024 McDonald diagnostic criteria and diagnosis of relapsing or progressive MS based on the 2013 Lublin phenotype criteria for multiple sclerosis;
• Relapsing-remitting multiple sclerosis (RRMS):
• patients with RRMS who have failed ≥ 1 highly effective disease modifying therapy (DMT) (fingolimod, siponimod, ozanimod, and anti-leukocyte cluster of differentiation [CD] 20 monoclonal antibody therapy, etc.) (defined as at least 12 months of continuous use).
• At least 2 clinical relapses in the past 2 years, or 1 clinical relapse in the past 2 years with ≥ 1 new Gd-enhancing lesion on MRI, or ≥ 1 new Gd-enhancing lesion on MRI within the past 6 months; c) ≥ 2 Gd-enhancing lesions on T1-weighted brain MRI at screening.
• Primary progressive multiple sclerosis (PPMS):
• patients with primary progressive MS who have failed highly effective DMT and whose disease activity has worsened recently (i.e., within 1 year) (EDSS disease progression score ≥ 0.5);
• no Gd-enhancing lesions on brain MRI at screening.
• Secondary progressive multiple sclerosis (SPMS):
• patients with secondary progressive MS who have failed highly effective DMT and whose disease activity has worsened recently (i.e., within 1 year) (EDSS disease progression score ≥ 0.5);
• no Gd-enhancing lesions on brain MRI at screening.
• 3.EDSS score ≥ 2.0 and ≤ 6.5;
• 4.Documented history or confirmation at screening of the presence of oligoclonal bands or an elevated IgG index or the KFLC index in CSF.

You may not qualify if…

• 1.Fungal, bacterial, viral, or other infection not controlled and/or requiring hospitalization or intravenous antimicrobial therapy within 4 weeks prior to screening. Uncomplicated urinary tract infection and uncomplicated bacterial pharyngitis are permitted if responding to current therapy;
• 2.Active tuberculosis or latent tuberculosis that has not been treated appropriately prior to screening;
• 3.History of severe hypersensitivity or allergy;
• 4.Primary immunodeficiency;
• 5.Impaired cardiac function or clinically significant cardiac disease;
• 6.History of serious respiratory diseases or current serious respiratory diseases, including moderate or severe or above asthma or chronic obstructive pulmonary disease, interstitial lung disease, or pulmonary fibrosis;
• 7.Current or history of cirrhosis;
• 8.History of Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus within the past 2 years, and the need for continuous use of systemic immunosuppressants/systemic disease-modifying drugs;
• 9.Any active malignancy or history of malignancy within 5 years prior to screening. The following are exceptions: early-stage tumors that have undergone radical treatment (carcinoma in situ or stage I tumors, non-ulcerative primary melanoma with a depth < 1 mm and no lymph node involvement), basal cell carcinoma of the skin, squamous cell carcinoma of the skin, thyroid carcinoma in situ or early-stage thyroid cancer that has undergone radical treatment, cervical carcinoma in situ, or breast cancer in situ that has undergone potentially radical treatment;
• 10.Those who have clinically significant bleeding symptoms or definite haemorrhagic diathesis within 6 months prior to screening;
• 11.Arterial or venous thrombotic events such as cerebrovascular disorders (including cerebral hemorrhage, cerebral infarction, etc), deep venous thrombosis, and/or pulmonary embolism within 6 months prior to screening;
• 12.Hematologic disorders: History of cytopenia consistent with myelodysplastic syndrome; history of sickle-cell anemia or other hemoglobinopathies;
• 13.Severe underlying medical conditions, such as:
• Significant clinical evidence of dementia or mental status changes;
• History of any other central nervous system (CNS) disorders or neurodegenerative diseases, such as epilepsy, seizure, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, and psychosis;
• Mental disorders or psychosocial conditions that place patients at unacceptable risk.
• 14.Positive results in any of the following tests:
• Positive for human immunodeficiency virus (HIV) antibody;
• Positive for hepatitis B surface antigen (HBsAg); or positive for hepatitis B core antibody (HBcAb) with hepatitis B virus deoxyribonucleic acid (DNA) above the lower limit of detection of the assay;
• Positive for hepatitis C virus (HCV) antibody with HCV ribonucleic acid (RNA) above the lower limit of detection of the assay;
• Positive for antibodies against human T-cell lymphotropic virus types I and II;
• Positive for syphilis antibody. As the immunosuppression included in this study may pose an unacceptable risk, those with active HIV infection, hepatitis B (positive for HBsAg), or HCV infection (positive for anti-HCV antibodies) are excluded. Subjects are allowed to have a previous history of hepatitis B or C, provided that viral load is shown to be below the limit of detection by quantitative polymerase chain reaction and/or nucleic acid testing. Hepatitis B surface antibodies produced following hepatitis B vaccination are not considered evidence of prior infection.
• 15.Administration of a live attenuated vaccine within 4 weeks prior to apheresis;
• 16.Receipt of a different investigational drug in a clinical trial within 4 weeks prior to apheresis, or the time interval from the last dose of the investigational drug in the previous drug clinical trial to the informed consent form (ICF) signing date is still within 5 half-lives of that drug (whichever is longer);
• 17.Splenectomy within 12 months prior to the signing of ICF;
