About this study
Official title: Evaluation of the Safety and Potential Effectiveness of Autologous Mesenchymal Stem Cells Transplantation in Subjects With Cervical Chronic and Complete Spinal Cord Injury
The purpose of this study is to analyze the safety and efficacy of autologous bone marrow mesenchymal stem cell transplantation in patients with cervical chronic and complete spinal cord injury.
Read the detailed description
This is a pilot, phase I study, in a prospective cohort. The study population will consist of 10 patients who had spinal cord injury for at least 12 months, with cervical chronic and complete spinal cord injury, ASIA grade A.
A practitioner, a surgeon and a nurse will review the medical records of the patients to determine the presence / absence of inclusion / exclusion criteria. If the patient is a potential candidate for the study, an interview will be scheduled to review and confirm his/her eligibility.
Patients will undergo a series of clinical and neurological assessments and will also be submitted to the following procedures:
- Cell blood count;
- Biochemical analysis (measurement of electrolytes - sodium, potassium, magnesium);
- Renal function tests (urea and creatinine);
- Liver function tests;
- Coagulation profile;
- Metabolic profile (glucose, total cholesterol and fractions);
- Urine summary and culture;
- Serology required for blood transfusion and marrow transplant in Brazil;
- Electrocardiogram;
- Chest X-Ray;
- Bone densitometry;
- Urodynamic studies;
- Somatosensory evoked potential;
- Computed tomography of thoracic and lumbar spine;
- Magnetic resonance imaging of the thoracic and lumbar spine.
Also as part of the preoperative evaluation, the patients will respond to questions from the SF (Short Form) -36 questionnaire (for assessment of quality of life) and the questionnaires for the assessment of neuropathic pain.
Clinical follow-up will be kept for patients who suspend their participation in the study for any adverse event and / or laboratory abnormality, or for the patient's own desire, following insurance protocols. In addition to the clinical and surgical follow-up, specific medical care will be offered to patients who experience adverse events, until stabilization of the patient, even if the target date for completion of the study has been exceeded.
The candidates included in the study will be asked to voluntarily participate and give their informed written consent.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Autologous mesenchymal cells transplantation in people with Spinal Cord Injury, run by Hospital Sao Rafael at 1 site in Brazil.
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 3 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 28 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ricardo Ribeiro-dos-Santos, PhD (557132816489, ricardoribeiro@cbtc-hsr.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with treatment-related adverse events as assessed by magnetic resonance imaging (time frame: 12 months). 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 NCT02574572, 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 28 Nov 2017.
