About this study
Official title: "Ex Vivo" Expanded Autologous Bone Marrow Mesenchymal Stem Cells Fixed in Allogenic Human Bone Tissue for Spinal Fusion in Spine Degenerative Disease
The present prospective, randomized study, compares the spinal fusion obtained after instrumentation and the use of a biologic product (patient's mesenchymal cells obtained from his/her own bone marrow which will be fixed in human bone tissue form a donor), with the current procedure that consists in instrumented spinal fusion and the use of each patient's bone obtained from his/her iliac crest.
The working hypothesis proposes that the tissue engineering is a valid and useful technique to achieve bone regeneration, avoiding the need for obtaining patient's iliac crest and its associated morbidity.
Read the detailed description
Prospective, open-label, randomized, parallel, single-dose phase I-II clinical trial in which 62 patients affected with L4-L5 degenerative spondylolisthesis grade I-II according to Meyerding and/or with L4-L5 degenerative discopathy needing spinal fusion will enter the trial with the primary objective of assessing the feasibility and safety of "ex-vivo" expanded autologous mesenchymal stem cells fixed in allogenic bone tissue in spinal fusion. Secondary objectives are to assess the efficacy of the implantation by imaging (computerized helicoidal tomography and X-ray) and clinical questionnaires (pain by visual analogue scale, quality of life by SF-36 and Oswestry Disability Index).
Patients will be randomized to one of the two treatment arms (instrumented spinal fusion and the tissue engineering product composed by "ex-vivo" expanded autologous mesenchymal stem cells fixed in allogenic bone tissue in spinal fusion or the standard treatment of instrumented spinal fusion and patient's bone iliac crest). Thereafter, patients will be followed for 12 months.
Imaging assessment will be done by an independent blinded radiologist.

Efficacy spinal fusion by imaging procedures (X-Ray).
Spinal fusion will be assessed by spinal X-Ray
Measured: 3, 6 and 12 months
Efficacy spinal fusion by imaging procedures (computerized helicoidal tomography)

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing XCEL-MT-OSTEO-ALPHA and Standard treatment in people with Lumbar Spondylolisthesis Involving L4-L5, and/or and Degenerative Discopathy Involving L4-L5, run by Banc de Sang i Teixits at 5 sites in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
safety of XCEL-MT-OSTEO-ALPHA (tissue engineering product composed by "ex-vivo" expanded autologous mesenchymal stem cells fixed in allogenic bone tissue in spinal fusion) (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01552707, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jan 2020; AzTrials last refreshed its copy on 7 Nov 2026.
