14 mai 2019 mis à jour par: Jesús Vaquero Crespo, M.D., Puerta de Hierro University Hospital

Subarachnoid Administrations of Adults Autologous Mesenchymal Stromal Cells in Patients Suffering Incomplete Spinal Cord Injury (SCI)

The study goes on 24 months, with recruiting, treatment and follow period for all patients. The first day for each patient will be the first cellular administration. 3 doses will be administrated every 3 months from first dose.

When the clinical trial finishes, it will be done a completed check of all obtained parameters.

Description détaillée

It is a clinical trial phase I, single center, non-randomized, uncontrolled, open prospective follow-up of a cohort of patients with chronic spinal cord injury (SCI) .10 patients will be included with this injury.

Primary objective: Analyze the possible clinical efficacy of administration of main adult mesenchymal autologous cells expanded "in vitro" in patients with incomplete and chronically established SCI.

Secondary objectives: Confirm the safety of treatment, and study possible changes in the cerebrospinal fluid (CSF) levels (Brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), ciliary neurotrophic factor (CNTF), Nerve Growth Factor 3 and 4(NT3 and NT4) after subarachnoid administration of BMMC.

Délai
Efficacy-Sensivity Improvement Using the ASIA Score
Délai: measure before treatment (baseline visit), 3, 6, 9 and 12 months after surgery
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.

Efficacy-Urodynamic Studies Bladder Compliance
Délai: measure before treatment (baseline visit), 6 and 12 months after surgery

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.
