Clinical Trial Summary

The aim of this study is to evaluate the efficacy and safety of intrathecal administration of autologous mesenchymal stem cells in participants with subacute spinal cord injury.

Clinical Trial Description

Spinal cord injury (SCI) constitutes a social and economic problem with the aggravating factor of being able to limit individual capacity, leading to a condition of unproductiveness and incapacity. At present, there is no effective treatment for recovering an injured spinal cord. Our research group was one of the pioneers in the study of mesenchymal stem cell therapies in the treatment of SCI, having carried out preclinical studies, as well as clinical studies with participants with complete spinal cord injuries, which demonstrated that stem cell transplantation mesenchymal (MSC) from autologous bone marrow was a safe and effective therapy in these studies. This project proposes the investigation of this therapy in participants with complete spinal cord injuries in the thoracolumbar region, in the subacute phase (defined between 3 to 6 months after the event), aiming to evaluate the safety and efficacy of the injection of mesenchymal stem cells. For this, we propose a double-blind, randomized clinical study to demonstrate the efficacy and safety of bone marrow MSC transplantation in participants with complete paraplegia, classified by ASIA Impairment Scale (AIS) grade A, by TRM, with subacute lesion. Forty participants will be referred by reference institutions and then recruited to be subsequently subjected to randomization, if eligible, with a group of 20 participants treated by intrathecal infusion of autologous MSCs, and another of 20 participants allocated to the control group, using a glucophysiological solution as a subcutaneous placebo. Each participant, after recruitment, will be monitored for a period of approximately 01 (one) year. The preparation of the CTMs will be done in accordance with the standards of good manufacturing practices. Both groups participating in the study will be submitted to pre- and post-treatment evaluations. The effectiveness of the therapy will be evaluated using the scale established by ASIA (American Spinal Injury Association) and the International Classification of Functioning, Disability and Health (ICF). ;
