Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Phase I, open-label, single-site, safety study of HSSC transplantation for the treatment of chronic spinal cord injury (SCI). Group A enrolled 4 subjects with a cord injury at T2-T12; Group B will enroll 4 subjects with a C5-C7 cord injury. Study period will be 6 months post-operative. Post-study, subjects will be followed for an additional 54 months.

3. Women must have a negative serum pregnancy test and practice an acceptable method of contraception or be of non-childbearing potential (post-menopausal for at least 2 years or who have undergone hysterectomy or oophorectomy or surgical sterilization)
4. At least 1 year but no more than 2 years from time of injury at the time of surgery
5. SCI injury classified as AIS-A complete as confirmed by the PI and a Physical Medicine and Rehabilitation doctor or other SCI Medicine board certified physician based on a complete ISNC SCI examination

5. History of Malignancy (except for non-melanoma skin cancer)
6. Primary or secondary immune deficiency

10. Any condition that the Investigator or primary physician feels may interfere with participation in the study
11. Any condition that the surgeon feels may pose complications for the surgery
12. Known hypersensitivity to basiliximab, tacrolimus or mycophenolate mofetil
13. Inability to provide informed consent as determined by screening protocol.
