About this study

Official title: EXO-SPINE: A Prospective, Multi-center, Double-blind, Randomized, Placebo Controlled Pivotal Study of Ultrasound as Adjunctive Therapy for Increasing Posterolateral Fusion Success Following Single Level Posterior Instrumented Lumbar Surgery

Adjunct therapy for increasing posterolateral fusion success following single level posterior instrumented lumbar surgery.

Read the detailed description

The purpose of this study is to determine whether using active low intensity pulsed ultrasound as adjunct therapy following single level posterior instrumented lumbar surgery increases the posterolateral success rate when compared to inactive (placebo) therapy.

Being tested
Exospine sham, Exospine, Exogen 4000+, Exogen 4000+ sham
Keywords

What is being measured

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

  1. Number of Participants With Posterolateral Fusion Success at the Treated Level

    Fusion success at the treated level was defined as at least 2 of 3 independent blinded radiologists agree all 3 of the following criteria were met.

    1. Confirmation of bridging bone based on computed tomography (CT) evidence of a continuous bony connection between the transverse processes on both posterolateral sides, assessed using a numeric grading scale.
    2. No evidence of motion defined as <5° angulation based on flexion and extension radiographs.
    3. No evidence of translational movement defined as <3 mm difference based on flexion and extension radiographs.

    Measured: 12 months post treatment start

Questions about this trial

What is this clinical trial studying?

A study testing Exospine and Exogen 4000+ in people with Lumbar Degenerative Disc Disease, run by Bioventus LLC.

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 4 inclusion and 2 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: stopped early, as of the sponsor's last update on 2 Apr 2021. 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. Some participants in this study may receive a placebo. 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 2 Apr 2021). 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?

Number of Participants With Posterolateral Fusion Success at the Treated Level (time frame: 12 months post treatment start). 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 2 Apr 2021.
