Overview

The primary purpose of this research study is to evaluate the safety and possible harms of injecting one's own Schwann cells along with nerve auto-graft after a severe injury to a major nerve has occurred.

Interventions

  • Biological Autologous Human Schwann Cell
    A one-time dose of 1000 μl\* or 80 to 100 million ahSC prepared from segments of the sural nerve from the leg recovered from the participant.

Primary outcome measures

  • Incidence of Treatment-related Adverse Events (AEs) [Time frame: Up to 2 years]
Secondary outcome measures (3)
  • Motor Recovery as assessed using the MRC Grading Scale [Time frame: Up to 2 years]
  • Sensory recovery as assessed by Pin-Prick Evaluation [Time frame: Up to 2 years]
  • Sensory recovery as assessed by the 2-Point Discrimination Evaluation [Time frame: Up to 2 years]

Eligibility criteria

Inclusion criteria

  • Persons with severe sciatic nerve injury, brachial plexus injury, and/or major nerve injury at the upper or lower extremity within previous year;
  • Between the ages of 18 and 65 at last birthday

Exclusion criteria

  • Persons unable to safely undergo an MRI;
  • Persons with pre-existing conditions that would preclude satisfactory sural nerve harvest;
  • Persons with severe peripheral nerve injury gap length > 10 cm;
  • Persons with history of radiation or local cancer in area of nerve injury, including primary tumors of the nerve;
  • Pregnant women or a positive pregnancy test in those women with reproductive potential prior to enrollment;
  • Presence of disease that might interfere with participant safety, compliance, or evaluation of the condition under study;
  • History of active substance abuse;
  • Persons allergic to gentamicin;
  • Persons who test positive for HIV or Hepatitis B or C virus.
  • Persons unable to provide consent independently due to cognitive impairment
