NCT02302157

Brief Summary

The purpose of this study is to evaluate the safety of cross sequential escalating doses of AST-OPC1 administered among 5 cohorts at a single time-point between 21 and 42 days post injury, inclusively, to subjects with subacute cervical spinal cord injuries (SCI).

Eligibility Criteria

Age18 Years - 69 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Sensorimotor complete, traumatic SCI (ASIA Impairment Scale A) for cohorts 1,2,3
  • Sensorimotor incomplete, traumatic SCI (ASIA Impairment Scale B) for cohorts 4,5
  • Last fully preserved single neurological level (SNL) from C-4 to C-7
  • From 18 through 69 years of age at time of injury
  • Single spinal cord lesion on a post-stabilization magnetic resonance imaging (MRI) scan, with sufficient visualization of the spinal cord injury epicenter and lesion margins to enable post-injection safety monitoring
  • Informed consent for this protocol and the companion long term follow-up protocol must be provided and documented (i.e., signed informed consent forms) no later than 37 days following injury
  • Able to participate in an elective surgical procedure to inject AST-OPC1 21-42 days following SCI

You may not qualify if:

  • SCI due to penetrating trauma
  • Traumatic anatomical transection or laceration of the spinal cord based on prior surgery or MRI
  • Any concomitant injury that interferes with the performance, interpretation or validity of neurological examinations
  • Inability to communicate effectively with neurological examiner such that the validity of patient data could be compromised
  • Significant organ damage or systemic disease that would create an unacceptable risk for surgery or immunosuppression
  • History of any malignancy (except non-melanoma skin cancers)
  • Pregnant or nursing women
  • Body mass index (BMI) \> 35 or weight \> 300 lbs.
  • Active participation in another experimental procedure/intervention
