About this study

The primary objective of this study is to compare the early clinical outcomes following non-surgical treatment with Triojection® to surgical discectomy. Early is defined as less than or equal to 6 months.

Read the detailed description

The objective of this study is to compare clinical, economic and safety outcomes between Triojection and surgical discectomy. The study will include two follow-up phases: 1) an initial follow-up period during the first 6 months after treatment and (2) a long-term follow-up lasting an additional 18 months (2 years total).

The hypothesis is that over the first six months after treatment, Triojection® will be non-inferior to discectomy with respect to the improvement in leg pain. This will be demonstrated using a non-inferiority margin of 19.4 points on the difference between baseline leg pain score and the average leg pain score recorded at 1 week, 1, 3 and 6 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TriojectionDevice

    Triojection is system intended to deliver a specific amount of ozone to a herniated disc.

  • Surgical discectomyProcedure or surgery

    Patients will receive surgery to remove the herniated disc material.

Study groups in NCT02525120
Study groupRoleWhat they receive
Triojection System for ozone injectionExperimentalTriojection is a system including a single-use sterile syringe cartridge and an accessory console. The console is interfaced to a supply of medical oxygen and uses this supply to fill the syringe with oxygen. Ozone is produced by applying a high voltage to electrodes physically located within the syringe. When a concentration of 35µg/ml is reached, the cartridge is removed from the console. The sterile syringe, containing the gas, is extracted from the protective housing and the gas is administered directly to the center of the herniated disc through a spinal needle.
Receives: Device: Triojection
Surgical discectomyActive comparatorThe surgical group will be receive a standard surgical discectomy to remove the herniated disc material.
Receives: Procedure: Surgical discectomy

What is being measured

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

  1. Leg pain NRS

    The primary outcome measure will be the amount of improvement in leg pain after treatment. This will be determined by taking the difference between the baseline score and the average of the post-treatment scores at 1 week, 1, 3 and 6 months.

    Measured: Baseline, 1 week, 1, 3 and 6 months.

Secondary outcomes (7)
  1. Leg pain NRS

    Leg pain Numerical Rating Scale (NRS) at each visit.

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  2. Back pain NRS

    Back pain Numerical Rating Scale (NRS) at each visit

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  3. Functional Score measured by RMDI.

    Roland Morris Disability Index. A 24 question survey asking the subject if they have difficulty with various activities of daily living.

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  4. Quality of Life measured by EQ-5D

    EQ-5D is a validated survey asking the subject 5 multiple choice questions and to indicate their general health status on a scale of 0-100.

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  5. Patient Satisfaction via a survey

    Brief questionnaire asking patients to rate their level of satisfaction.

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  6. Cost Diary

    Survey asking patients to detail their medical expenses, work status, time off work etc.

    Measured: Baseline and 1 week, 1, 3, 6, 12, 18 and 24 months after treatment.

  7. Review of MRI images

    Blinded, independent MRI review to determine reduction in disc herniation following treatment and evaluate index and adjacent levels for evidence of degeneration.

    Measured: Baseline and 6 and 24 months after treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Triojection and Surgical discectomy in people with Lumbar Disc Herniation, run by Minimus Spine, Inc at 3 sites in 3 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 10 inclusion and 19 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: status not confirmed, as of the sponsor's last update on 6 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Greece, Italy, 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Leg pain NRS (time frame: Baseline, 1 week, 1, 3 and 6 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 6 Jun 2018; AzTrials last refreshed its copy on 6 Nov 2026.
