Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the safety and preliminary efficacy of NeoFuse in subjects with a diagnosis of degenerative disc disease (DDD) in 1 or 2 adjacent vertebral levels between L1 and S1. All subjects in this study will undergo interbody fusion via Transforaminal Lumbar Interbody Fusion (TLIF) or Posterior Lumbar Interbody Fusion (PLIF) procedures with Food and Drug Administration (FDA) approved/cleared supplemental posterior instrumentation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, multicenter, randomized, open-label controlled Phase 2 study designed to evaluate the safety and preliminary efficacy of adult, allogeneic mesenchymal precursor cells (MPCs) combined with MasterGraft Matrix when compared to use of autologous iliac crest bone graft in the lumbar interbody fusion site in subjects requiring 1 or 2 level interbody fusion procedure with instrumentation. All subjects in this study will undergo a 1 or 2-level (2 or 3 vertebrae) interbody fusion with supplemental posterior instrumentation.

After the screening and surgical visits, each subject will be evaluated clinically and radiographically within 3 days and 30 days after surgery, and at 3, 6, 9, 12, 24, and 36 months after surgery.

Subjects will be evaluated at the same time points for safety.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male or females at least 18 years of age, but not older than 70.
2. Have the ability to understand the requirements of the study, to provide written informed consent, and to comply with the study protocol.
3. Have the ability to understand and provide written authorization for the use and disclosure of personal health information (PHI) \[per Health Insurance Portability and Accountability Act (HIPAA) privacy ruling in the US\].
4. Have a documented symptomatic diagnosis of DDD at L1-S1 with or without stenosis and with or without up to and including Grade II degenerative spondylolisthesis.
5. Have clinical symptoms of neurogenic claudication.
6. Have failed 6 months of non-operative low back pain management.
7. Are candidates for posterior lumbar interbody fusion in combination with posterior pedicle screw stabilization and require surgery at a 1 or 2 adjacent vertebral levels between L1 and S1.
8. Have 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.

* Male subjects with partners of childbearing potential must agree to use adequate contraception (barrier method or abstinence) from the time of surgery and for a period of at least 1 year after surgery.
2. Have 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. Have 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.
4. Have a documented medical history or radiographic evidence of a metabolic bone disease or other condition which would negatively impact the bone healing process.
5. Have a positive screen for human immunodeficiency virus (HIV) antibodies.
6. Have 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 3-year follow-up period.
7. Have been a recipient of prior stem cell/progenitor cell therapy for spinal fusion surgery.
8. Have a body mass index (BMI) \> 35.
9. Have 20% or greater anti-human leukocyte antigen (HLA) antibody titer and/or has antibody specificities to donor HLA antigens.
10. Are transient or has been treated in the last 6 months before enrollment for alcohol and/or drug abuse in an inpatient substance abuse program.
