Rebooting the immune system: can a stem cell transplant stop aggressive MS?
NCT ID NCT06228781
First seen Oct 16, 2026 · Last updated Oct 16, 2026
Summary
Researchers are testing a personalized stem cell transplant for people with multiple sclerosis that has not responded to standard treatments. The procedure collects a patient's own blood-forming stem cells, uses strong chemotherapy to reset the immune system, and then returns the cells to rebuild it. The goal is to achieve long-term remission without needing ongoing MS drugs. The trial enrolls 20 adults with active, disabling MS and tracks whether they stay free of relapses and new brain lesions for three years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- autologous hematopoietic stem cell transplantation
- What this could lead to
- If it works, this approach could give people with hard-to-treat multiple sclerosis years of symptom-free life without needing daily medication.
- What could go wrong
- The chemotherapy used to wipe out the immune system is intense and carries serious risks, including infection and organ damage. The trial is small, and some patients may still see their MS return years later.

Inclusion Criteria: 1. Age 18-60 years; 2. Diagnosed multiple sclerosis with relapses or progression and sustained accumulated impairment by a neurologist expert in the field; 3. EDSS score of 3-6 (including 3 and 6); 4. EDSS cerebellar functional score ≥ 3 or EDSS pyramidal functional score ≥3; 5. Evidence of current disease activity; 6. If a patient has previously received a cytotoxic agent (mitoxantrone, cyclophosphamide etc.) they must have normal bone marrow morphology and cytogenetics before being considered eligible for this study ; 7.

Patients having received a cytotoxic agent within one month of enrolling in this study; 3. Patient with any active or chronic infection (herpes simplex virus, varicella-zoster virus, cytomegalovirus, EB virus, human immunodeficiency virus, hepatitis virus, syphilis, etc.); 4. Patients having received a cytotoxic agent within one month of enrolling in this study; 5. Patients with a malignant tumor currently or within the last 5 years; 6. Patients with cardiac, renal, pulmonary, hepatic or other organ impairment; 7. Patients whose life expectancy is severely limited by another conditions; 8. Pregnancy or risk of pregnancy; 9. Patients unable to give written informed consent in accordance with research ethics board guidelines.
