A Safety and Tolerability Study of Neural Stem Cells (NR1) in Subjects With Chronic Ischemic Subcortical Stroke (ISS)
February 20, 2024 updated by: Gary Steinberg, MD, PhD
A Phase 1/Phase 2a Safety and Tolerability Study of Intracerebral Transplantation of Neural Stem Cells (NR1) in Subjects With Chronic Ischemic Subcortical Stroke (ISS) and Early Evaluation of Potentially Useful Efficacy Parameters
Evaluation of the safety and tolerability of escalating doses of NR1 administered intracerebrally at a single time-point post-injury to subjects with chronic ISS with or without cortical stroke.
Study Overview
Detailed Description
Evaluation of the safety and tolerability of escalating doses of NR1 administered intracerebrally at a single time-point post-injury to subjects with chronic ISS with or without cortical stroke.
The study will be a dose escalation using up to 4 cohorts each at a single dose level, of intracerebral administration of NR1 cells.
Secondary objectives are to evaluate clinical and radiologic responses as well as utility of efficacy measurement tools.
