Dose Escalation Study of AST-OPC1 in Spinal Cord Injury

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

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).

Arm Intervention/treatment
Experimental: AST-OPC1
Open label, dose escalation, cross-sequential cohort of subjects who receive an injection or two injections of AST-OPC1 at a single time-point
Biological: AST-OPC1
One injection of 2 million or 10 million AST-OPC1 cells, or 2 injections of 10 million AST-OPC1 cells for a total of 20 million cells; cohort dependent

Primary Outcome Measures :
  1. Number of Adverse Events Within 1 Year (365 Days) That Are Related to AST-OPC1 Injection [ Time Frame: One Year ]
    Numbers of adverse events within 1 year (365 days) that are related to AST-OPC1 injection

Secondary Outcome Measures :
  1. Neurological Function as Measured by Upper Extremity Motor Scores and Motor Level on International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) Examinations as Secondary End Point - 365 Days After Injection of AST-OPC1 [ Time Frame: One Year ]

    The scale is based on the ISNCSCI (International Standards for Neurological Classification of Spinal Cord Injury) that measures the severity of Spinal cord injury. The data was collected per time point during the first year (30,60,90,180,270,365). The 365-days time point was pre-specified as Secondary Outcome Measure. High score means better outcome. Units are "Scores on a scale".

    The score is divided to motor scale (0-100) and sensor scale (0-224).

    Motor scale is divided to subscale of upper extremity (0-50) and lower extremity (0-50).

    Upper and lower extremity are divided to subscale of Right (0-25) + Left (0-25).

    Each upper & lower extremity is divided to subscale of 5 motor nerve function (0-5).

    Sensor scale is divided to subscale of light touch (0-112) and pin prick (0-112).

    light touch and pin prick are divided to subscales of Right (0-56) + Left (0-56).

    Each right and left light touch and pin prick are divided to subscales of 28 sensor nerve function (0-2)

Accepts Healthy Volunteers:   No

Major Inclusion Criteria:

  • Sensorimotor complete, traumatic SCI (ASIA Impairment Scale A) for cohorts 1,2,3
