Brief summary

The purpose of this study is to determine the long term safety and preliminary effect of HuCNS-SC cells transplanted in subjects with Connatal Pelizaeus-Merzbacher Disease (PMD).

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.
