Study Description

Brief Summary:

A double-blind, randomized, cross-over phase I/II study to evaluate the safety and the efficacy of the intravenous administration of autologous Mesenchymal Stem Cells (MSC) to patients with active multiple sclerosis (MS) resistant to currently available therapies.

Condition or disease	Intervention/treatment	Phase
Multiple Sclerosis	Biological: Autologous Mesenchymal Stem Cells	Phase 1; Phase 2

Detailed Description:

The mechanism of action of MSC relies on their ability to modulate pathogenic immune responses and provide neuroprotection through the release of anti-apoptotic, anti-oxidant and trophic factors as demonstrated by in vitro and in vivo preclinical studies.

Patients will be randomized to receive immediate vs. delayed treatment with either a dose equal to 1-2 millions/kg of body weight of autologous MSC, or equivalent volume of suspension media at baseline. At 6 months treatments will be reversed.

The primary outcome of this study is to evaluate

• treatment's safety within one year from MSC administration by measuring the the number, time-frame and severity of adverse event and
• treatment's activity in terms of reduction in the total number of contrast-gadolinium enhancing lesions (GEL) by magnetic resonance imaging (MRI) scans.

Secondary outcomes are to gain preliminary information on the efficacy of the experimental treatment in terms of combined MRI activity and clinical efficacy (incidence of relapses and disability progression).

Study Design

• Study Type: Interventional (Clinical Trial)

Arms and Interventions

Arm	Intervention/treatment
Experimental: Autologous Mesenchymal Stem Cells; At week 0 a single infusion of either ex-vivo expanded autologous MSC or suspension media will be administered intravenously at a dose of 1-2 x 1000000 MSC/Kg body weight. At week 24, another infusion will be performed for cross-over re-treatment: at week 24 treatments will be reversed compared to week 0	Biological: Autologous Mesenchymal Stem Cells; Single dose of 1-2 x 1000000 cells/Kg body weight
Placebo Comparator: Suspension media; At week 0 a single infusion of either ex-vivo expanded autologous MSC or suspension media will be administered intravenously at a dose of 1-2 x 1000000 MSC/Kg body weight. At week 24, another infusion will be performed for cross-over re-treatment: at week 24 treatments will be reversed compared to week 0

Secondary Outcome Measures :

1. Efficacy [ Time Frame: 48 weeks from the first infusion ]
   Number of GEL counted over week 28, 36 and 48 compared with the number of GEL counted over 4, 12 and 24 weeks.
2. Efficacy [ Time Frame: 24 weeks form the first infusion ]

3. Efficacy [ Time Frame: 48 weeks from the first infusion ]
   Combined unique MRI activity, volume of GEL and volume of BH over week 28, 36 and 48 compared with the same outcomes over 4, 12 and 24 weeks.
4. Efficacy [ Time Frame: 48 weeks from the first infusion ]
   Number of relapses in MSC treatment group vs. placebo group in the first 24 weeks and after cross-over re-treatment in the two groups.
5. Efficacy [ Time Frame: 48 weeks from the first infusion ]
   Time to sustained progression of disability and proportion of progression-free patients compared between treatment groups during the first 24 weeks and after cross-over
