Hematopoietic Stem Cell Transplantation for Treatment of Multiple Sclerosis in Sweden

CompletedN/A

Sponsor: Uppsala University

Conditions: Multiple Sclerosis, Multiple Sclerosis, Relapsing-Remitting

Interventions: Autologous hematopoietic stem cell transplantation

Countries: Sweden

This is an observational cohort study with retrospective analysis of prospectively collected data. The study cohort is constituted of all patients with relapsing-remitting multiple sclerosis (RRMS) treated with autologous stem cell transplantation (AHSCT) in Sweden from 2004 when the first AHSCT was performed until 31 December 2019. The study aims to describe the effectiveness, safety and patient reported outcomes of AHSCT for MS through real world data. Treatment related mortality will be analyzed from start of mobilization until the end of the study. For other adverse events the data collection will end 3 months post-transplantation. A statistical subgroup comparison of efficacy and safety between the conditioning regimens BEAM-ATG and Cy-ATG will be included within the study.
