A Study of IMS001 in Patients With Multiple Sclerosis
A Clinical Study of IMS001 Injection (Human Embryonic Stem Cell-Derived Mesenchymal-Like Stem Cells) for the Treatment of Multiple Sclerosis
This study will evaluate the safety and tolerability of IMS001 and explore its possible effects in adults with multiple sclerosis. IMS001 is an investigational cell therapy consisting of mesenchymal-like stem cells derived from human embryonic stem cells.
The study plans to enroll 4 adults aged 18 to 65 years with relapsing-remitting or secondary progressive multiple sclerosis in China. Each participant will receive a single infusion of IMS001 into a vein. All participants will receive IMS001, and both participants and the study team will know which treatment is given.
Participants will undergo screening for up to 4 weeks before treatment. After the infusion, they will be assessed over 12 months for side effects and changes in multiple sclerosis, including relapses, disability, brain magnetic resonance imaging (MRI) findings, vision, movement, and thinking abilities.
Participants will then enter an additional 24-month follow-up period to monitor long-term safety, including serious side effects and possible tumor development. Total participation may last up to 37 months, including screening.

-
Has relapsing-remitting multiple sclerosis (RRMS) or secondary progressive multiple sclerosis (SPMS), diagnosed according to the 2017 McDonald criteria.
-
Has an Expanded Disability Status Scale (EDSS) score of 3.0 to 7.5, inclusive.
-
Has experienced at least one of the following despite disease-modifying therapy (DMT):
- One relapse within the year before screening, or at least two relapses within the two years before screening.
- Confirmed disability progression, as assessed by the investigator.
- Gadolinium-enhancing T1 lesions and/or new or enlarging T2 lesions on magnetic resonance imaging (MRI).
-
Has had no clinical relapse within one month before screening.
-
Has had multiple sclerosis for more than one year.
-
Women of childbearing potential must agree to use effective contraception during the study and for six months after the last dose of study treatment, and must have negative pregnancy tests at screening and baseline.
-
Male participants with partners of childbearing potential must agree to use effective contraception for three months after the last dose of study treatment and must not donate sperm during this period.
-
Is able and willing to undergo gadolinium administration and repeated MRI examinations.
Exclusion Criteria:
- Known or suspected allergy to human serum albumin, diphenhydramine, acetaminophen, methylprednisolone, or any component of IMS001.
- Use of teriflunomide within 12 months before screening, unless an 11-day elimination procedure using cholestyramine or another appropriate elimination agent has been completed.
- Use of alemtuzumab within 12 months before screening, or cladribine, rituximab, ocrelizumab, or another anti-CD20 monoclonal antibody within six months before screening.
- Use of ofatumumab, natalizumab, or ozanimod, or treatment with plasma exchange, within three months before screening.
- Use of mitoxantrone, cyclophosphamide, azathioprine, methotrexate, cyclosporine, mycophenolate mofetil, fingolimod, siponimod, ponesimod, or systemic corticosteroids within one month before screening.
- Use of interferon beta-1a/1b, glatiramer acetate, dimethyl fumarate, diroximel fumarate, or monomethyl fumarate within two weeks before screening. Generic equivalents of glatiramer acetate and dimethyl fumarate are included.
- Previous treatment with any allogeneic cell therapy or tissue transplantation.
- History of a neoplastic disease, except basal cell carcinoma; nonmetastatic cutaneous squamous cell carcinoma excised with clear margins; adequately treated cervical carcinoma in situ; or low-risk differentiated papillary thyroid carcinoma or noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) that has been definitively treated, without recurrence, and meets the required disease-free survival criteria.
- Clinically significant electrocardiogram abnormalities during screening.
- Known or documented HIV or syphilis infection, or active hepatitis B or hepatitis C infection.
- Abnormal liver function, including total bilirubin greater than 2 times the upper limit of normal (ULN), except isolated Gilbert syndrome, or AST or ALT greater than 3 times ULN.

- Estimated glomerular filtration rate below 30 mL/min/1.73 m² during screening, calculated using the 2021 CKD-EPI equation; acute kidney injury; need for renal replacement therapy; or another clinically significant active or unstable kidney disease, as judged by the investigator.
- History of another autoimmune disease, myelodysplasia, or a hematological disease.
- Pregnancy, breastfeeding, or plans to become pregnant during the study.
- Inability to receive study treatment during the trial, likely noncompliance with the protocol, or any other circumstance considered unsuitable by the investigator.
