Intervention Details:
  • Biological: Autologous Human Schwann Cells
    Schwann cells harvested from the sural nerve and debrided, injured sciatic nerve of the participant will be autologously transplanted along sural nerve autografts wrapped in a collagen matrix

Layout table for eligibility information
Ages Eligible for Study:   16 Years to 16 Years   (Child)
Sexes Eligible for Study:   Female

Inclusion Criteria:

  • Persons with severe sciatic nerve injury, brachial plexus injury, and/or major injury at the upper or lower extremity with nerve loss within previous year;
  • Peripheral nerve injury with large gap (5 - 10 cm) between healthy nerve endings;

Exclusion Criteria:

  • Persons unable to safely undergo an MRI (may include persons with an implanted device or metallic fragments which may interfere with MRI safety);
  • Persons with pre-existing conditions that would preclude satisfactory sural nerve harvest (may include amputation or major injury to lower limb, or disease affecting the sural nerve);
  • Persons with severe peripheral nerve injury gap length > 10 cm in length;
  • 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 transplantation;
  • Presence of disease that might interfere with participant
