Trial Outcomes & Findings for Subarachnoid Administrations of Adults Autologous Mesenchymal Stromal Cells in SCI (NCT NCT02165904)

NCT ID: NCT02165904

Last Updated: 2019-07-19

Results Overview

Sensitivity improvement was measured using the ASIA (American Spinal Injury Association) scale to measure the Surface sensitivity (LTS), pain sensitivity (PPS), and the degree of motor function in key muscles (MS). The sum of MS, LTS, and PPS configure total ASIA score. A minimum possible score is 0 points. A maximum possible score is 224 points for a patient with normal sensation. ASIA score was obtained before surgery, and 3, 6, 9 and 12 months after surgery. Mean and standard deviation for the 10 patients were obtained at all the time points and statistically analyzed.

Urodynamic studies in terms of Bladder compliance. Bladder compliance is the result of a mathematical calculation of volume responsible for 1 cm H2O pressure rise measured during a cystometric filling . It gives an indication on how the different mechanisms in the bladder wall react on stretching. It is obvious that compliance figures can vary widely in groups which makes it difficult to define limits of normality.

Changes in expression of neurotrophins in CSF (CerebroSpinal Fluid) samples obtained previously to first administration of cell therapy, and previously to the last administration, at month 10, in order to study the variability in the expression of neurotrophins along time. The mean+SD (standard deviation) at each time point was obtained. The tested neurotrophins were: BDNF.
