Key Points
Question Is nonmyeloablative autologous hematopoietic stem cell transplantation (HSCT) more effective than disease-modifying therapy for patients with highly active relapsing-remitting multiple sclerosis (MS)?
Findings In this randomized clinical trial that included 110 patients with relapsing-remitting MS, treatment with nonmyeloablative HSCT compared with disease-modifying therapy resulted in a significantly prolonged time to disease progression (hazard ratio, 0.07).
Meaning In this preliminary study, nonmyeloablative HSCT was more effective than disease-modifying therapy for patients with relapsing-remitting MS.
