Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Neural Stem cells injected intracerebrally

Arm Description

Subject cohorts will be treated with increasing doses of Neural Stem Cells injected intracerebrally using a traditional 3+3 trial design

Outcomes

Primary Outcome Measures

Incidence of Treatment-Emergent Adverse Events
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Fugl Meyer (FM) motor score
Change in neurologic functional outcome to evaluate efficacy post-injection as defined by change in Fugl Meyer motor score in comparison to baseline

5. Study Description

Brief Summary
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.
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.
