Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Surgically/direct sterile application of 10 Million Mesenchymal Precursor Cells and Mastergraft Matrix made of medical grade combination of purified collagen and biphasic calcium phosphate ceramic. The collagen is highly purified (>95%) Type I bioresorbable lyophilized collagen. The biphasic ceramic portion of MasterGraft(TM) Matrix is provided in a 15% hydroxyapatite and 85% b-tricalcium phosphate formulation. The cells and matrix will be prepared/combined and implanted at each involved cervical level for a total dose of 20 or 30 million cells or mastergraft granules only per involved cervical level. The duration of an anterior cervical discectomy and fusion procedure is 2-3 hours.

Outcomes
Primary outcome [1] 237989 0

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation envelopes prepared by a biostatistitian with assigned/allocaed randomisation numbers. Once the patient is found to be eligible and surgery date confirmed, an unblided study delegate will select an envelope and assign the randomisation number and treatment to the patient.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible subjects will be randomized to receive one of two treatments at each fusion level: NeoFuse TradeMark (TM) 10 million allogeneic MPCs per involved interbody space combined with MasterGraft (TM) Granules or MasterGraft(TM) Granules alone (control). The treatment will be administered as a direct sterile application to the involved level(s), for a total dose per study subject of either 20 or 30 million MPCs if study subject randomised to 10 million MPCs. Randomisation numbers will be assigned as per the randomisation envelopes preprapared by the biostatitician. The biostatistitian will use a simple randomisation table to create the code placed in the envelopes. This table will be generated using computer software (i.e., computerised sequence generation). The envelopes will be supplied to the cell storage facility and the unblinded persnnel will select the next envelope in sequence that will indicate the randomisation number and dose for that patient.
