A Not for Profit Phase II Study to Evaluate Safety, Efficacy and Biomarkers secondary endpoints of Human Neural Stem cell intracerebroventricular transplantation in amyotrophic lateral sclerosis patients: a randomized, placebo controlled, triple blind study.
This is an approximate 24-months study (PHASE B) consisting, per patient, of a 30-day screening period, 12-month enrollment and follow up period. A preliminary 3+3 dose-escalation open-label phase (PHASE A) will be performed in order to test the toxicity of the two proposed cell doses. The study will be stopped when all the subjects included in the treatment period complete the study visits. The study uses an ATMP, for that reason all the patients follow up will be prosecuted long life.
