Cell Therapy by Autologous BMC for Large Bone Defect Repair

BMC2012, Cell Based Therapy by Implanted Bone Marrow-derived Mononuclear Cells (BMC) for Bone Augmentation of Plate-stabilized Proximal Humeral Fractures - a Randomized, Open, Multicentric Study - Phase IIa

In the present phase-II clinical trial the researchers investigate efficacy and proof of concept of the augmentation with preoperatively isolated autologous BMC cells seeded onto ß-TCP in combination with an angle stable fixation (Philos plate®) for the therapy of proximal humeral fractures.

Inclusion Criteria:

• patients aged between 50. and 90. years with proximal humerus fractures
• indication for open reposition and internal stabilisation with a proximal fixed- angle plate for humerus (PHILOS, Synthes, Oberdorf, Swiss):
• 2-, 3- or 4-fragment fracture according to Neer
• dislocation of >10 mm between fragments and/or
• angle of > 45° between fragments and/or
• dislocation of tuberculum majus > 5 mm
• negative pregnancy test of premenopausal women
• signed informed consent for surgery and participation in the clinical trial

Exclusion Criteria:

• contraindications against administration of Investigational medicinal product (IMP) is pregnancy and nursing
• dislocation fracture
• known psychic disorder that leads to incompliance (e.g. dementia, schizophrenia, major depression)
• pathologic fractures caused by other underlying diseases
• fracture-induced nerve damage
• tumor disease with recent adjuvant therapy or treatment during the last 3 months (e.g. chemotherapy, radiotherapy), untreated tumor diseases
• known hypersensibility against components of the transplant
• participation in a clinical trial during the last 3 months prior to this study
