Safety and Preliminary Efficacy Study of NeoFuse in Subjects Requiring Lumbar Interbody Fusion
Study Details
Study Description
Brief Summary
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.

Phase 2 |
Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- To determine the overall safety of NeoFuse plus carrier using physical examinations, vital signs, treatment emergent adverse events (TEAEs), and the results of clinical lab tests (hematology, serum chemistry, inflammation, and immunology). [3 years]
Secondary Outcome Measures
- To evaluate the overall fusion success with NeoFuse plus carrier compared to autograft using CT scans and x-ray of the involved lumbar spine levels and assess the change in outcomes (ODI, SF-36, and WPAI) and pain (VAS)at the 12-month follow-up visit. [3 years]
Eligibility Criteria
Criteria
Inclusion Criteria:

-
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.
-
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.
-
Have a documented medical history or radiographic evidence of a metabolic bone disease or other condition which would negatively impact the bone healing process.
-
Have a positive screen for human immunodeficiency virus (HIV) antibodies.
-
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.
-
Have been a recipient of prior stem cell/progenitor cell therapy for spinal fusion surgery.
-
Have a body mass index (BMI) > 35.
-
