Overview
Brief Summary
In this study we want to evaluate the clinical use of allogenic mesenchymal stem cells (MSC), obtained from bone marrow of healthy donors, for treatment of Degenerative Disc Disease (DDD). The trial is based in previous results with autologous MSC (Orozco et al., Transplantation 92: 822-828; 2011). Here we propose a phase I-II trial, prospective, randomized, blinded, and controlled for the treatment DDD using MSV, a Good Manufacturing Practice (GMP)-compliant expanded bone marrow MSC (MSV, Investigational medicinal product Num. 10-134). The assay consists of two arms with 12 patients each one. Patients in the experimental arm will be given a single intra-discal transplantation of MSV (25 millions in 2 ml). Control patients will be infiltrated in the paravertebral muscles close to the lesion with 2 ml of 1% mepivacain. We shall follow the evolution of pain, disability and quality of life as well as disc fluid content by Magnetic Resonance Imaging (T2-calibrated).

- •Informed written consent of the patient.
Exclusion Criteria
- •Age over 75 or under 18 or legally dependent
- •Allergy to gentamicin, or to bovine, cattle or horse serum.
- •Congenital or acquired diseases leading to spine deformations that may upset cell application.

Intervention: Mepivacaine
Outcomes
Primary Outcomes
Pain and Disability Evaluation
Time Frame: Change since the baseline (before intervention) up to the end of the follow-up period, 12 months after the intervention
Change in the composite variable, which includes pain and disability 1 year after intervention, was plotted as a function of the initial pain score or disability index. Results for the relief of lumbar pain and Oswestry disability index were all included for both, control and cell-treated patients. The scores obtained from this analysis (slope of the plot) range from 0 to 1, with higher scores meaning a better outcome.
Secondary Outcomes
- Oswestry Disability Index at 3 Months(At 3 months after the intervention)
- Oswestry Disability Index at 12 Months(At 12 months after the intervention)
- SF-12 Physical Component at 6 Months(6 months after the intervention)
- Evaluation of Affected Disc(s) by Quantitative MRI Ratio 12/6months(At 12 months from 6 months after the intervention)
- Visual Analogue Scale at 12 Months(At 12 months after the intervention)
