Mesoblast, Ltd. Identifier:
First received: April 16, 2010
Last updated: December 15, 2016
Last verified: December 2016
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) at 2 or more adjacent cervical vertebral levels between C3-C4 to C7-T1. All subjects in this study will undergo 2 or 3 level anterior cervical discectomy and fusion with Anterior Cervical Plate Fixation.

Primary Outcome Measures:
  • Safety of NeoFuse [ Time Frame: 2 years ]
    To determine the safety of NeoFuse using physical examinations, vital signs, treatment emergent adverse events (TEAEs), and the results of clinical lab tests (hematology, serum chemistry, inflammation, and and immunology).

Secondary Outcome Measures:
  • Fusion success with NeoFuse [ Time Frame: 1 year ]
    To evaluate the fusion success with NeoFuse compared to an active control using CT scans and x-ray of the involved cervical spine levels and assess the change in outcomes (NDI, SF-36, Zung Depression Questionnaire, and WPAI.

Enrollment: 12
Study Start Date: June 2010
Study Completion Date: March 2013
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: NeoFuse
Anterior Cervical Discectomy and Fusion with NeoFuse
Procedure: NeoFuse
Single Dose NeoFuse Surgical Implantation
Other Names:
  • Anterior Cervical Discectomy and Fusion with NeoFuse
  • Cervical Spinal Fusion
  • Adult Stem Cells
Active Comparator: MasterGraft Granules
Anterior Cervical Discectomy and Fusion with MasterGraft Granules
Procedure: MasterGraft Granules
Single Dose MaterGraft Granules Surgical Implantation
Other Names:
  • Anterior Cervical Discectomy and Fusion with Granules
  • Cervical Spinal Fusion
  • Active Control

Detailed Description:

This is a prospective, multicenter, randomized, single-blinded, controlled study evaluating safety and preliminary efficacy of immunoselected, culture-expanded, nucleated, allogeneic MPCs (NeoFuse) combined with MasterGraft Matrix in a commercially available PEEK cervical Spacer compared to an active control in subjects undergoing 2 or 3 level anterior cervical discectomy and fusion with anterior cervical plate fixation.

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, 12, and 24 months after surgery.

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

Accepts Healthy Volunteers:   No

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.

  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:

  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.
