NCT02440074

Brief Summary

This trial pretends to validate for clinical use a bioengineered product composed of mesenchymal stem cells produced by the Instituto de Biologia y Genetica Molecular (IBGM), Valladolid (MSV, which have already been approved by the Spanish Regulatory Agency for three previous clinical trials) and a cross-linked matrix of autologous plasma patented by The Blood and Tissue Bank of Asturias (WO2008/ 119855) for bone maxillary cysts refilling. These two groups collaborate in the present project with the team of Maxillofacial Surgery of the Hospital Universitario del Río Hortega, who leads the clinical trial and deals with the medical aspects. The proposed trial is based on positive results obtained in previous animal studies performed by the present multidisciplinary team. A phase I / II clinical trial with 10 patients suffering from bone cysts in the maxillofacial region is proposed. Autologous mesenchymal stem cells isolated from a bone marrow sample will be seeded in the autologous plasma matrix and cultivated for 3 weeks. At this time, the cyst will be removed by surgery and the cavity filled with the protein matrix containing the mesenchymal cells. Follow up tests will be conducted at 3 weeks, 3 and 6 months following the evolution of the cavity by panoramic radiography and computerized tomography scan.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Degenerative disease of one or two lumbar discs with predominant back pain after conservative treatment (physical and medical) for over 6 months.
  • Fibrous ring capable of holding the cell implantation, demonstrated by Magnetic Resonance Imaging (MRI; stages 2, 3 and 4 of Adams).
  • Decrease of disc height of more than 20% (radiographic measurement in side image).
  • Absence of spinal infection.
  • Haematological and biochemical analysis wit no significant alterations that contraindicates intervention.
  • The patient is able to understand the nature of the study.
  • Informed written consent of the patient.

You may not qualify if:

  • 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.
  • Spinal segmental instability, spinal canal stenosis, isthmus pathology and other conditions that may compromise the study
  • Modic III changes on MRI images (31).
  • Overweight with body mass index (mass in Kg/size in m2) greater than 35 (obesity grade II).
  • Pregnancy or breast-feeding
  • Neoplasia
  • Immunosuppression
  • Other conditions that may, according to medical criteria, discourage participation in the study.
