MS stem cell transplant study: tracking immune reboot after treatment
NCT ID NCT07635693
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 20 adults with multiple sclerosis who are already scheduled for a stem cell transplant. Researchers will measure levels of an immune-suppressing drug called ATLG and track how the immune system rebuilds itself afterward. The goal is to learn more about immune recovery and viral infections, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ATLG (anti-T-lymphocyte globulin)
- What this could lead to
- If successful, this study could help doctors better understand how the immune system recovers after stem cell transplant in MS, potentially improving future treatment protocols.
- What could go wrong
- This is a small observational study, not a treatment trial. It will not directly test whether ATLG or the transplant works for MS, so results may not change current care.

Who can take part

Who is studied
The study will involve 20 MS patients, treated with autologous HSCT as standard-of-care according to guidelines and consensus recommendations. Autologous HSCT is considered a standard-of-care intervention in the following selected MS patients: RRMS who have failed to respond to one or more high-efficacy DMTs or progressive MS with superimposed inflammatory activity, or aggressive forms of MS where rapid neurological decline occurs early in the disease course. Patients will receive standard conditioning regimen (BEAM or cyclophosphamide) and ATLG (total dose 30 mg/kg over 3 days: 10 mg/kg on days -3, -2 and -1).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participant is willing and able to give informed consent for participation in the study. * Adult patients (age \>/= 18y) * Diagnosis of MS * Confirmed program of autologous HSCT according to standard EBMT indications (any conditioning regimen considered standard, BEAM or Cyclophosphamide) * ATLG (total dose 30 mg/kg over 3 days: 10 mg/kg on days -3, -2 and -1) in the conditioning regimen. Exclusion Criteria: * Subjects that did not accept to sign the informed consent. * Use of ATG. * Contraindications to HSCT procedures (including pregnancy and breast feeding, uncontrolled active infections)
