Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with multiple sclerosis planned for autologous HSCT using standard conditioning regimens including BEAM or Cyclophosphamide and ATLG at 30 mg/kg total over 3 days.
✕Probably not a fit
Patients who do not receive ATLG or who are not undergoing autologous HSCT would not be expected to benefit from this study.

What this trial studies
This prospective, multicenter, observational study will describe ATLG dynamics and immune reconstitution in people with MS receiving autologous HSCT. It will collect biological data to describe ATLG pharmacokinetics and related immune changes, providing baseline variability and trends to inform future research. No clinical decisions will be made within the study, and interim analyses will not influence study conduct or stopping rules. The study aims to generate descriptive findings rather than to determine treatment efficacy. Data will come from standard EBMT-indicated conditioning regimens including BEAM or Cyclophosphamide.
Why it matters
Potential benefit: If successful, the study could improve understanding of ATLG behavior and immune reconstitution after autologous HSCT in MS, informing future trials.
How similar studies have gone: Previous observational work in similar HSCT contexts has described pharmacokinetics and immune reconstitution, but this specific ATLG-focused MS HSCT study is exploratory and builds on related but limited prior data.
