Safety Study of Human Neural Stem Cells Injections for Secondary Progressive Multiple Sclerosis Patients

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.
