Effect of Nonmyeloablative Hematopoietic Stem Cell Transplantation vs Continued Disease-Modifying Therapy on Disease Progression in Patients With Relapsing-Remitting Multiple Sclerosis

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.
