About this study

Official title: "Elaspine™ Implant System Post Marketing Clinical Study: A Prospective, Multicentre Study to Evaluate the Safety and Performance of the Elaspine™ System in the Surgical Treatment of Degenerative Lumbar Spine"

The safety and performance of the Elaspine™ Implant System in the treatment of lower back pain will be evaluated with a prospective and nonrandomized, multicenter post-marketing clinical study (PMCS). The study will be enrolled within Germany and Switzerland in 3-5 clinical centres, including in average 10 patients per centre. The study is conducted in accordance with the Standard ISO 14155, where applicable on clinical investigation of medical devices for human subjects and other legal requirements.

What is being measured

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

  1. Safety

    Incidence (including severity) of operative and post-operative complications throughout the first 3 months postoperatively by category (general, operative, post-operative, possibly device related etc.)

    Measured: 24 months

  2. Performance

    Defined as the incidence of device complications and device malfunctions (including severity), as assessed by radiographic evaluation throughout the first 12 months post-operatively. Device malfunctions include, but are not limited to loosening or breakage of the pedicle screws, disassembly of the locking clip, breakage of the rod, pathological motion or stiffness of the segments and disc collapse. Reading of the imaging studies will be centralized at an independent facility.

    Measured: 24 months

Secondary outcomes (3)
  1. Changes in function status (ODI), back pain (VAS) and health status (SF-12) at two-years post-operatively will be measured and compared to the preoperative baseline

    Measured: 24 months

  2. Changes in neurologic function at two-years post-operatively as compared to the preoperative baseline by motor, sensory, reflexes and straight leg raise

    Measured: 24 months

  3. Changes in angular range of motion from maximum flexion to extension between preoperative baseline and the two-year postoperative outcome assessed by radiographic imaging (dynamic xrays)

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A study testing Elaspine™ in people with Lower Back Pain, run by Spinelab AG at 5 sites in 2 countries.

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 17 inclusion and 25 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 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Germany, Switzerland. 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?

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?

Safety (time frame: 24 months). The study lists 2 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 17 Nov 2015.
