简要总结
This is a long term follow-up study to investigate the safety and efficacy of CARTISTEM®, human umbilical cord blood-derived mesenchymal stem cells, in repair of cartilage injury or defects, compared with microfracture. Subjects who participated in and completed the Phase III trial (NCT01041001) will be tracked until the 60 month post-treatment timepoint.
详细描述
This long term follow-up study is performed to assess the long-term safety and efficacy of CARTISTEM®, human umbilical cord blood-derived mesenchymal stem cells, in repair of cartilage injury or defects, compared with microfracture. Subjects, who were either administered CARTISTEM or treated with conventional microfracture in the primary phase III study (NCT01041001), will be further observed using various subjective knee assessments and MRI T2 mapping until the 60 month post-treatment timepoint.
