Brief Summary:
The objective of the study is to determine if the cell therapy NC1 administered in the spinal cord is effective for the treatment of a post-traumatic syringomyelia. The post-traumatic syringomyelia is the development and progression of cyst filled with cerebrospinal fluid (CSF) within the spinal cord. The cell therapy NC1 consist on cells obtained from the bone marrow of the patient, that are cultured in vitro and administered in the spinal cord of the same patient.

Condition or disease Intervention/treatment Phase
Post-Traumatic Syringomyelia Biological: NC 1 cell therapy Phase 2

Detailed Description:
Phase II, Open, prospective, not controlled, not randomized clinical trial in patients affected by post-traumatic syringomyelia. The trial evaluates the efficacy of the cell therapy NC1 administered via intrathecal in the location of the injury. After the administration of the cell therapy, patients will undergo physiotherapy during the follow-up period (6 months). Patients will be evaluated at month 3 and month 6 after the NC1 administration.
