Randomized placebo-controlled phase II trial of autologous mesenchymal stem cells in multiple sclerosis.

ABSTRACT:

Objective

Uncontrolled studies of mesenchymal stem cells (MSCs) in multiple sclerosis suggested some beneficial effect. In this randomized, double-blind, placebo-controlled, crossover phase II study we investigated their safety and efficacy in relapsing-remitting multiple sclerosis patients. Efficacy was evaluated in terms of cumulative number of gadolinium-enhancing lesions (GEL) on magnetic resonance imaging (MRI) at 6 months and at the end of the study.

Methods

Patients unresponsive to conventional therapy, defined by at least 1 relapse and/or GEL on MRI scan in past 12 months, disease duration 2 to 10 years and Expanded Disability Status Scale (EDSS) 3.0-6.5 were randomized to receive IV 1-2×10(6) bone-marrow-derived-MSCs/Kg or placebo. After 6 months, the treatment was
