A Study of Modified Stem Cells in Traumatic Brain Injury (TBI)
A Double-Blind, Controlled Phase 2 Study of the Safety and Efficacy of Modified Stem Cells (SB623) in Patients With Chronic Motor Deficit From Traumatic Brain Injury (TBI)
The primary purpose of the clinical study is to evaluate the clinical efficacy of intracranial administration of SB623 cells on patients with chronic motor deficit from Traumatic Brain Injury. A secondary purpose of the study is 1) to evaluate the effect of intracranial administration of SB623 cells on disability parameters and 2) to evaluate the safety and tolerability of intracranial administration of SB623 cells. Patients with stable, chronic motor deficits secondary to focal traumatic brain injury must be 12 months post TBI.
SB623 cells are adult bone-marrow-derived cells that are transiently transfected with a plasmid construct encoding the intracellular domain of human Notch-1. These cells produce trophic factors that protect neurons in models of ischemic insult. In a rat contusion model of TBI, implantation of SB623 around the area of the injury resulted in significant improvement of motor function. Further, safety evaluation of animal models implanted with SB623 cells have shown no adverse effects and no SB623-related clinical, laboratory, or histological abnormalities were found. A 2-year Phase 1/2A dose escalation study (NCT01287936) of SB623 stereotactically implanted into the brains of patients with chronic motor deficits due to ischemic stroke has completed.The study has shown statistically-significant improvements in motor function in each of three scales: the European Stroke Scale (ESS), the National Institute of Health Stroke Scale (NIHSS) and the Fugl-Meyer scale. The study showed no serious adverse events likely attributed to SB623, and only minor adverse events mostly grade 1 or 2 (with one grade 3) that were unrelated, unlikely related, or possibly related to SB623. No dose-limiting toxicities were observed.

  • Clincially significant finding on MRI of brain not related to TBI
  • Known presence of any malignancy except squamous or basal cell carcinoma of the skin
  • History of CNS malignancy
  • Positive findings on tests for occult malignancy, unless a non-malignant etiology is confirmed

  • Uncontrolled major psychiatric illness, including depression symptoms (CESD-R Scale of ≥16)
  • Unexplained abnormal preoperative test values (blood tests, electrocardiogram [ECG], chest X-ray); x-ray evidence of infection; uncontrolled atrial fibrillation or uncontrolled congestive heart failure
  • Presence of craniectomy (without bone flap replacement) or other contraindication to stereotactic surgery
  • Participation in any other investigational trial within 4 weeks of initial screening or within 7 weeks of study entry
  • Botulinum toxin injection, phenol injection, intrathecal baclofen, or any other interventional treatments for spasticity (except bracing and splinting) 16 weeks priot to the Baseline visit.
