Mesenchymal Stromal Cells for Ischemic Stroke (SAMCIS)

April 16, 2018 updated by: Sean Savitz

SAfety of Mesenchymal Stromal Cells for Ischemic Stroke

The purpose of this study is to determine if mesenchymal stem cells given by IV is feasible and safe in patients with recent ischemic stroke and to decide the maximum tolerated dose when given between 3-10 days after an ischemic stroke.

Detailed Description

This is a randomized, double-blind, placebo controlled study. . Approximately 48 subjects will be enrolled in the trial, undergo a real or SHAM MSC IV infusion and will be follow out to 1 year. There will potentially be 4 Cohorts with the dose escalation at a 3:1 randomization schedule

Objectives:

  • The primary hypothesis' are that intravenous administration of allogeneic bone marrow derived mesenchymal stem cells is feasible and safe in patients with recent ischemic stroke and to determine the maximum tolerated dose (MTD) of IV MSCs when administered sub-acutely between 3-10 days following ischemic stroke.
  • The secondary hypothesis is that allogeneic MSC transplantation will improve functional outcome after recent ischemic stroke.

Safety and clinical efficacy points to be evaluated at Day 7 clinic visit, Day 30, Day 60, Day 90, and Day 180. Primary outcome or Primary endpoint of the study is to define the safety or harm of the MSCs
