Primary Outcome Measures:
  • Incidence of serious adverse events (SAEs), results of physical and neurological examination, laboratory tests and vital signs. [ Time Frame: 4 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Preliminary efficacy using Bayley-III and Callier-Azusa Scale. [ Time Frame: 4 years ] [ Designated as safety issue: No ]
    Changes compared to baseline

  • Changes in brain magnetic resonance imaging (MRI), electroencephalogram (EEG), seizure frequency and somato-sensory evoked potentials (SSEP). [ Time Frame: 4 years ] [ Designated as safety issue: No ]
    Changes compared to baseline

Groups/Cohorts Assigned Interventions
HuCNS-SC transplanted subjects in the lead-in phase
Subjects who had HuCNS-SC transplant in the lead-in phase study CL-N01-PMD
Biological: HuCNS-SC transplant in the lead-in phase
Long-term safety follow-up study

Detailed Description:

Only subjects who underwent HuCNS-SC transplantation under Protocol CL-N01-PMD will be enrolled in this long term follow-up study.

Subjects will return to the site six months and one year after completion of the Phase I study and then annually for a total study duration of four years. Phone calls will also be made by the Investigator to the subject's parent/legal guardian bi-annually to conduct a phone visit through the four-year duration of the study.
