Safety and Efficacy Study of NeoFuse in Subjects Undergoing Multi-Level Anterior Cervical Discectomy and Fusion

Inclusion Criteria:

1. Male or females between 18 and 70 years of age, inclusive.
2. Has the ability to understand the requirements of the study, to provide written informed consent, and to comply with the study protocol.
3. Has the ability to understand and provide written authorization for the use and disclosure of personal health information (PHI).
4. Has a documented symptomatic diagnosis of DDD at C3-C4 to C7-T1.
5. Has symptomatic radiculopathy and/or myelopathy correlating to radiographic findings of duration of 6 weeks or greater that had failed to respond to non-operative management
6. Is a candidate for anterior cervical discectomy and fusion in two or three adjacent cervical interbody levels between C3-C4 to C7-T1
7. Has a stable screening electrocardiogram (ECG), as determined by the investigator that would not preclude surgery.

Exclusion Criteria:

1. Female subjects who are pregnant or nursing, or women planning to become pregnant during the first year (12 months) following surgery.
2. Has a current or prior history within the last 3 years of neoplasm (excluding basal cell carcinoma) and/or any active neoplasm within the last 24 months, prior to screening.
3. Has at the time of surgery a systemic or local infection at the site of proposed surgery.
4. Has or is undergoing revision of a prior fusion surgery at any involved level.
5. Requires ACDF at only one cervical interbody level or more than 3 adjacent cervical interbody levels.
6. Requires ACDF without the use of an anterior cervical plating system.
7. Has osteoporosis as defined by a DEXA T score of ≤ -3.0 or a history of fragility fractures or other significant bone disease contraindicating the use of spinal instrumentation.
8. Has a documented medical history or radiographic evidence of a metabolic bone disease or other condition which would negatively impact the bone healing process.
9. Has a positive screen for human immunodeficiency virus (HIV) antibodies.
10. Has had treatment with any investigational therapy or device within 6 months of study surgery and/or plans to participate in any other allogeneic stem cell/progenitor cell therapy trial during the 2-year follow-up period.
11. Has been a recipient of prior stem cell/progenitor cell therapy for spinal fusion surgery.
12. Has 20% or greater anti-human leukocyte antigen (HLA) antibody titer and/or has antibody specificities to donor HLA antigens.
13. Is transient or has been treated in the last 6 months before enrollment for alcohol and/or drug abuse in an inpatient substance abuse program.
