Outcome Measures

Primary Outcomes (3)

  • Incidence and severity of adverse events (AEs)

    Information will be collected on all adverse events through Year 5 and on late-occurring adverse events (Years 6-15) related to any changes in neurological condition, a fever of unknown etiology, and the development of neoplasias and/or neurological disorders.

    Up to 15 years after AST-OPC1 injection

  • Changes from baseline greater than 1.5x or 2x in chemistry and hematology panel results over 5 years after injection of AST-OPC1

    Summary statistics will be tabulated for chemistry and hematology laboratory parameter results and change from baseline to Year 5, as applicable, by cohort and overall. A table counting abnormal flags based on the respective lab's reference ranges by time point will be generated for each cohort and overall. At each visit, for each parameter, the number of subjects with low, normal, high, and clinically significant assessments will be tabulated.

    Up to 5 years after AST-OPC1 injection

  • Changes at the injection site as monitored by MRI

    MRI scans will monitor the brain and cervical spine for any possible long-term changes that could be related to AST-OPC1

    Up to 5 years after AST-OPC1 injection

Secondary Outcomes (1)

  • Changes in neurologic function as assessed by the ISNCSCI

    Up to 5 years after AST-OPC1 injection

Study Arms (1)

Subjects treated with AST-OPC1 in the initial dosing study AST-OPC1-01

Subjects treated with AST-OPC1 in the initial dosing study AST-OPC1-01 will be followed for 15-year long-term safety monitoring

Diagnostic Test: Magnetic Resonance Imaging (MRI)

Interventions

Observational study; annual MRI for first 5 years only to monitor changes in the injection site

Subjects treated with AST-OPC1 in the initial dosing study AST-OPC1-01
