About this study

Official title: A Prospective, Feasibility, Multi-Center Nonrandomized Clinical Trial Evaluating the Safety and Effectiveness of NuNec® Cervical Arthroplasty System

The objective of this study is to evaluate long-term safety and effectiveness of the NuNec® Cervical Arthroplasty System in a small patient population. The NuNec device is currently CE marked and commercially available in Europe.

Read the detailed description

The NuNec® feasibility study is a prospective, multi-centered, non-randomized clinical trial. Only patients who have been diagnosed with single level, C3 to C7, symptomatic cervical degenerative disc disease and have failed at least 6 weeks of conservative treatment or present signs of progression of spinal cord/nerve root compression with continued non-operative care will be enrolled.

Patients will be evaluated preoperatively and postoperatively at discharge, 6 weeks, 3, 6, 12 and 24 months.

What is being measured

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

  1. Neck Disability Index (NDI) Score Improvement of at Least 15 Points

    The Neck Disability Index is a patient reported outcome measure for self-rated disability due to neck pain. Each of the 10 items is scored from 0 - 5. The maximum score is therefore 50. The obtained score can be multiplied by 2 to produce a percentage score. A higher score would indicate that the patient did not improve.

    Measured: At 24 months

  2. Visual Analog Scale (VAS) Improvement of 2.0 cm for Neck Pain

    The pain Visual Analog Scale is a uni-dimensional measure of pain intensity, represented by a 100 mm line, anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 100 [100-mm scale]). A higher score would indicate that the patient had a worse outcome.

    Measured: At 24 months

  3. Serious Adverse Events Related to the Device

    The number of serious adverse events have been recorded

    Measured: Up to 24 months

  4. Device Failures or Removals, Revisions, Re-operations

    The failures or re-operations or supplemental fixation at the treated level

    Measured: Up to 24 months

Secondary outcomes (2)
  1. Patient Satisfaction

    As assessed on patient questionnaire.

    Measured: At 24 months

  2. Absence of Device Migration or Subsidence

    Absence of device migration > 3mm; Absence of device subsidence > 3mm

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A study testing NuNec Cervical Disc in people with Cervical Intervertebral Disc Degeneration, run by Pioneer Surgical Technology, Inc. at 1 site in United Kingdom.

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 6 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: stopped early, as of the sponsor's last update on 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 15 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Neck Disability Index (NDI) Score Improvement of at Least 15 Points (time frame: At 24 months). The study lists 4 primary outcomes in all. 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 15 Feb 2019.
