|Condition or disease||Intervention/treatment||Phase|
|Degenerative Disc Disease||Drug: Suspension of human autologous MSC 3P in 1.5 ml||Phase 1 Phase 2|
Following informed consent collection at the screening visit and verification of all inclusion and exclusion criteria, eligible patients will undergo the procedure of bone marrow cell aspiration from iliac crest for the purpose of receiving autologous multipotent mesenchymal stem cells. The cells will be cultivated for 3 passages (for 3 - 4 weeks) in order to expand them to sufficient quantity. Suspension of the cultured AMSC will then be sterilely packed and transported to the surgery site. During the posterolateral spine fusion operation, 1.5 ml of cell suspension will be mixed with 5 cc of beta-tricalcium phosphate foam (Vitoss™, Orthovita) and 3.5 ml of patient's blood, and inserted between the transverse processes of the lumbar spine.
All subjects will be hospitalized and followed up as per standard medical care rules used in the investigational site hospital for this type of intervention.

Experimental: Human AMSC (passage 3) 3P in 1.5 mL
Patient receiving the investigational medicinal product - suspension of human autologous MSC 3P in 1.5 mL
Drug: Suspension of human autologous MSC 3P in 1.5 ml
During the posterolateral spine fusion operation, 1.5 ml of cell suspension was mixed with 5cc of beta-tricalcium phosphate foam and 3.5 ml of patient's blood, and inserted between the right transverse processes of the lumbar spine.
Other Name: hAMSC
- Safety: To demonstrate absence of complications at the site of spinal fusion [ Time Frame: 1 year ]
Complications at the site of spinal fusion and other treatment-related adverse events will be recorded in ten patients at Visits I through VII. All adverse events (AEs) will be classified by seriousness, severity and relationship to hAMSC application.
All AEs will be collected as symptoms spontaneously reported by the patient, clinically relevant changes and abnormalities observed by the Investigator (clinically significant laboratory measurements confirmed by repeated measurement, results of physical examinations) Intensity
The following 3-point rating scale will be used for rating of the intensity of each AE:
Mild: Awareness of signs or symptoms, but no disruption of usual activity Moderate: Event sufficient to affect usual activities (disturbing) Severe: Inability to work or perform usual activities (unacceptable)
- Efficacy: To assess the quality of life determined by Oswestry Questionnaire. [ Time Frame: 1 year ]The quality of life determined by Oswestry Questionnaire will be recorded in ten patients at Visits II, and IV through VII. The test has 10 sections and maximum score is 50 points; change from the baseline valie will be recorded. The points are then transferred into percentage and interpreted in a standard way when 0-20% means minimal disability while 81-100% means bed-bound condition. Minimum detectable change (90 % confidence) is 10 % (5 points).
- Efficacy: To assess the quality of spinal fusion by X-ray imaging [ Time Frame: 1 year ]
The quality of spinal fusion will be measured by X-ray imaging at Visits V and VII. Dynamic X-ray of the lumbar spine will be performed at 3 and 12 months following the surgery and hAMSC application to measure the angle of the spine movement in the fusion area. The angle will be recorded in degrees. The movements above 10 degrees will beregarded as "unstable".
The bone fusion morphology will be evaluated based on the following scale:
- Cyst or pseudo-cyst formation
- Fusion not visible
- Pseudo-joint (or false joint) development
- Low degree of bone fusion
- High degree of bone fusion
- Efficacy: To assess the quality of spinal fusion measured by computed tomography (CT). [ Time Frame: 1 year ]
The quality of spinal fusion will be measured by CT in ten patients at Visits V and VII.
The density will of the fusion will be expressed as % on a linear scale between two standardized measuring points: soft tissue= 0%, vertebral arch= 100%.
