Study Details

Study Description

Brief Summary

This will be a phase I, open, multicenter, international study performed by 3 participating centres across two countries (Italy and Switzerland). Fifteen to 24 patients affected by SPMS will be enrolled, according to a "standard" phase I design over 18 months. All patients will enter a 3 months run in phase. Thereafter they will receive one of four different doses of allogenic hNSCs (dose A=5 millions hNSCs; dose B=10 millions hNSCs; dose C=16 millions hNSCs; dose D=24 millions hNSCs). Following hNSCs injection, all SPMS patients will receive immunosuppression with tacrolimus for 6 months. Patients will be clinically followed monthly for 1 year and then every 6 months for the 5 years following the study completion (possibly all life long).

MRI assessments will be performed monthly for the first 6 months and then every 3 months for 5 years following the study completion.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Human Neural Stem Cells Suspension Intraventricular injections of Allogenic human Neural Stem Cells (hNSCs) in four different dosages (5, 10,16 or 24 millions)	Biological: Human Neural Stem Cells; Allogenic human Neural Stem Cells (hNSCs) in four different dosages (5, 10, 16 or 24 millions). hNSCs are produced by the Laboratorio Cellule Staminali of Terni according to GMP guidelines and are obtained from brain specimens of several fetal human donors from spontaneous miscarriages occurred after the 8th week after conception.

Outcome Measures

Primary Outcome Measures

1. Incidence of Treatment Emergent AE [1 year]

   To Evaluate the Feasibility, Safety and Tolerability of intracerebroventricular injection of allogenic hNSCs

2. Percentage of Mortality in treated patients [1 year]

   Percentage of subjects (%) with death due to procedure (mortality correlated to treatment)

Secondary Outcome Measures

1. Change in Functional disability [Up to 1 year]

   this will be measured by the change of the Expanded Disability Scale (EDSS-disability score about pyramidal, cereberral, brainstem, sensory, bowel and bladder, visual, cerebral Functional Systems) during the study period.

2. Change in Functional disability [Up to 1 year]

   this will be measured by the change of the the Multiple Sclerosis Functional Composite (MSFC-scores about upper extremity function, ambulation and cognitive function) during the study period.

3. Activity of Cognitive function [Up to 1 year]

   This will be measured as the mean change of the score of the RAO Brief Repeatable Battery of Neuropsychological Test, during the study period.

4. Relapses Rate [Up to 1 year]

   Relapses will be measured by the change in EDSS scale

5. Relapses Rate [Up to 1 year]

   Relapses will be measured by the Imaging evaluations

6. MS Biomarkers [Up to 1 year]

   Investigation of potential candidate biomarkers able to monitor disease activity and predict clinical course in MS (Neurofilaments)

7. Alteration in Neurophysiological parameters [Up to 1 year]

   Assessed by Evoked Potentials.
