Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Male or female patients with cervical spondylosis, degenerative disc disease (DDD), or herniated nucleus pulposus (HNP) who are to receive cervical spine surgery with anterior column support at two or three contiguous levels (C2-C7)

Who may be able to join

  • Candidates who satisfy ALL of the following inclusion criteria and consent to participate in the study may be considered eligible for enrollment:
  • Diagnosed by the investigator with at least one (1) of the following:
  • Symptomatic cervical spondylosis;
  • Degenerative disc disease (DDD), defined as discogenic pain with degeneration of the disc confirmed by history and imaging studies;
  • Herniated nucleus pulposus (HNP)
  • Subjects who are candidates and have already elected to undergo contiguous two or three-level ACDF surgery between C2-C7 of the cervical spine
  • Skeletally mature adults between 21 and 75 years of age
  • Subjects, who, in the opinion of the Investigator, are able to understand the purpose of the study and are willing to return for all the required post-operative standard of care follow-up visits and have their data collected.

Who cannot join

  • Candidates who meet ANY of the following exclusion criteria are not considered eligible for study participation:
  • Posterior instrumentation necessary at same levels being treated
  • Instability associated with major reconstructive surgery for primary tumors or metastatic malignant tumors of the cervical spine
  • Instability associated with cervical spine trauma
  • Acute or chronic systemic or localized spinal infections
  • Previous deep anterior cervical surgeries such as thyroid, carotid, or high thoracic surgery (T5 and above)
Show all 21Show fewer
  • History of previous cervical fusion surgery at greater than one level
  • Previous pseudoarthrosis at any level of the cervical spine
  • Nursing mothers or women who are pregnant or plan to become pregnant during the time of the study
  • Severe osteoporosis (per the Investigator's diagnosis or per a T-score greater than or equal to 2.5 SD below the mean for a young, healthy adult) that may prevent adequate fixation of screws and thus preclude the use of a cervical plate system
  • Subjects who have a known or suspected allergy to any of the following antibiotics and/or reagents: Gentamicin Sulfate, Meropenem, Vancomycin, Dimethyl Sulfoxide (DMSO), and Human Serum Albumin (HSA)
  • Immune compromised subjects
  • Pre-existing neurological abnormalities other than deficits produced by the spinal fusion (e.g. MS, Parkinson's, CVA, diabetic neuropathy, peripheral neuropathy)
  • Conditions that could preclude the possibility of fusion in the Investigator's opinion (e.g. cancer, kidney dialysis, smoking, uncontrolled diabetes, osteopenia)
  • History of pre-operative dysphagia
  • Symptomatic shoulder pathologies under active treatment
  • Known sensitivity to device materials
  • Subjects who, in the opinion of the Investigator, have any other existing condition that would compromise their participation and follow-up in this clinical study
  • Intraoperative exclusion criteria:
  • Intraoperative decision by the surgeon to use implants not compatible or cleared for use with ViviGen
  • Intraoperative decision by the surgeon to use other bone grafts substitutes such as DBM or rhBMP

About this study

Official title: A Multi-Center, Prospective, Single-Arm Study of Patients Undergoing a Two or Three Level ACDF Using ViviGen Cellular Bone Matrix in Conjunction With Cervical Allograft Spacers and DePuy Synthes Spine Anterior Cervical Plate Systems

The purpose of this post-market study is to collect data on ViviGen and how its use affects fusion rates in the cervical spine when used as additional grafting material to fill the cervical spacer. The patient population of interest is patients who have already elected to undergo a 2-3 level ACDF surgical procedure using ViviGen, per standard of care.

  • ViviGenOther

    Also called ViviGen Cellular Bone Matrix

    ViviGen Cellular Bone Matrix is a formulation of cryopreserved viable cortical cancellous bone matrix and demineralized bone. ViviGen is a Human Cells, Tissues, and Cellular and Tissue-based Product (HCT/P) as defined by the U.S. Food and Drug Administration in 21 CFR 127 1.3(d).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fusion

    An independent radiologist will review films to determine fusion

    Measured: 12 Months

Secondary outcomes (8)
  1. VAS (Visual Analog Scale)

    Patient neck and arm pain reported on a VAS

    Measured: 12 Months

  2. NDI (Neck Disability Index)

    Functional success based on results from the NDI

    Measured: 12 Months

  3. SF-12

    Quality of life using SF-12 questionnaire

    Measured: 12 Months

  4. OR (Operating Room) Time

    Length of time to complete the two or three level ACDF (Anterior Cervical Discectomy and Fusion) using ViviGen

    Measured: 0 Days

  5. Length of Hospital Stay

    Length of time the patient remains in the hospital before being discharged after their two or three level ACDF using ViviGen

    Measured: 12 Months

  6. Return to Work

    How many patients return to work after having their two or three level ACDF using ViviGen

    Measured: 12 Months

  7. Adverse Events

    Rate of adverse events (AEs)

    Measured: 12 Months

  8. Time to Fusion

    Time to fusion as assessed by plain films

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

An observational study of Cervical Spondylosis and Degenerative Intervertebral Discs, run by DePuy Spine.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fusion (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2026.
