Clinical Trial Summary

Pediatric severe traumatic brain injury (TBI) is the leading cause of death and disability in children ages 1-14 years old. There are no effective therapies to treat secondary brain injury and the post-injury response of CNS apoptosis and neuroinflammation. This study is a follow-up trial from a previously performed Phase I trial that demonstrated the safety and potential CNS structural preservation effect of intravenous autologous bone marrow mononuclear cells (BMMNC) after severe TBI in children. (Cox, 2011) The study is designed as a prospective, randomized, placebo controlled, blinded Phase 2 safety/biological activity study. The investigators hope to determine the effect of intravenous infusion of autologous BMMNCs on brain structure and neurocognitive/functional outcomes after severe TBI in children.


Clinical Trial Description

Study Design: Multicenter, randomized, blinded, placebo controlled, Bayesian adaptive dose escalation design. Study Intervention: Single dose administered within 48 hours from time of injury. Controls will undergo a sham harvest and receive similarly labeled/external appearance and volume of 0.9% NaCl. BMMNC's will be harvested and undergo processing under cGMP conditions to obtain 6x10^6 cells/kg or 10x10^6 cells/kg weight. The cellular product/placebo will be infused within 48 hours of injury. Safety Monitoring & Follow-Up: Subjects will be monitored for infusion related toxicity post-infusion through hospital discharge and follow-up return study visits. Laboratory and imaging studies will be repeated at the 1, 6, and 12-month follow-up visits. A medical safety monitor (MSM) will review blinded SAE reports following post-infusion Day 14 for each subject in real time to ensure good clinical practice and to quickly identify safety concerns. The MSM will remain blinded to the treatment assignment, unless the NINDS appointed DSMB approves unblinding. ;
