Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    This study is designed to provide evidence to potentially inform future treatment of sciatica secondary to prolapsed disc. Transforaminal epidural steroid injection is recognised as a treatment alternative to surgical microdiscectomy, but it is not known how effective and cost effective this treatment is in comparison. This trial will compare the epidural steroid injection and microdiscectomy, and examine the impact of the different treatments on several outcomes such as Oswestry Disability Questionnaire scores, other back and leg pain questionnaires, and health economic analyses.

    The primary outcome will be the Oswestry Disability Questionnaire (ODQ; a condition specific outcome measure with over 30 years of scientific validation) at 18 weeks follow up (approx. 3 months after treatment).
    E.2.2Secondary objectives of the trial
    Secondary outcomes include Oswestry Disability Questionnaire (ODQ) at 30, 42 and 54 weeks (6, 9 and 12 months after randomisation), numerical rating scores for leg and back pain, Likert scale to measure patient satisfaction with treatment at 54 weeks (12 months after intervention), Modified Roland-Morris outcome scale for sciatica, Core Outcome Measures Index (COMI), work status, quality of life and health economic outcomes. These questionnaires focus on the leg and back pain of the patient, and how the symptoms impact on various aspects of their lives.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients with the following characteristics will be eligible for inclusion in the trial:

    a. Diagnosed lower extremity radiculopathy (sciatica)
    b. Sciatica secondary to prolapsed intervertebral disc (PID) (proven by MRI)
    c. Duration of symptoms between 6 weeks and 12 months
    d. Leg pain non-responsive to conservative, non-invasive management
    e. Age 16 – 65 years
    f. Patient has attempted at least one form of conservative (non-operative) treatment* but this has not provided adequate relief of patient’s pain/symptoms
    g. Patient has provided written, informed consent
    E.4Principal exclusion criteria
    Patients with the following characteristics will be excluded from the trial:

    a. Serious neurological deficit (e.g. foot-drop/possible cauda-equina compression)
    b. Previous spinal surgery at the same intervertebral disc (level)
    c. Sciatica presentation for longer than 12 months
    d. Age < 16
    e. Age > 65
    f. Patient has not attempted any form of conservative treatment
    g. Any patient who has a contraindication for surgery and/or injection
    h. Patient known to be pregnant
    E.5 End points
    E.5.1Primary end point(s)
    Oswestry Disability Questionnaire at 3 months post-intervention.

    The primary outcome measure of Oswestry Disability Questionnaire (ODQ) has over thirty years of validation and is supported by OMERACT for low back pain research. Studies have recommended the use of ODQ as part of the core outcome measures for low back research. This outcome measure is supported by OMERACT in low back research. The scale ranges from 100 (extreme disability) to zero (extreme ability). A change of 10 points has been widely regarded in the literature as the minimal clinical significance. One study specifically addressing this issue has suggested a range 0f 10.5 to 15 as clinically important. ODQ has over 30 years of validated, published data pertaining to low-back pathology and radicular symptoms. It has formed the basis for previous HTA trials exploring sciatica and will allow useful comparisons to be made to previous data.
    E.5.1.1Timepoint(s) of evaluation of this end point
    ODQ at 18 weeks post-randomisation, assumed to be approximately 3 months post-intervention.

    ODQ score change at 18 weeks versus baseline will be evaluated.
    E.5.2Secondary end point(s)
    a. ODQ at 18, 30, 42 and 54 weeks
    b. Visual analogue pain scores for leg pain at baseline, and at 18, 30, 42 and 54 weeks
    c. Visual analogue score for back pain at baseline, and at 18, 30, 42 and 54 weeks
    d. Likert Scale to assess patient treatment satisfaction at 54 weeks
    e. Modified Roland-Morris outcome scale for sciatica at baseline, and at 18, 30, 42 and 54 weeks
    f. Core Outcome Measures Index (COMI) at baseline, and at 18, 30, 42 and 54 weeks
    g. Work status (return to work)
    h. Cost-effectiveness, expressed as the incremental cost per quality-adjusted life-year (QALY) based on the EQ-5D-5L
    E.5.2.1Timepoint(s) of evaluation of this end point
    Significant timepoints of the trial are:
    - baseline
    - treatment (approx. 6 weeks)
    - 18 weeks
    - 30 weeks
    - 42 weeks
    - 54 weeks
    The secondary endpoints will be evaluated from information obtained at each of these timepoints

    The end of the trial is the date of database lock as defined in the Data Management Plan. At the time of database lock, data entry privileges are withdrawn from the trial database. However, the trial may be closed prematurely by the Trial Steering Committee, or on the recommendation of the Independent Data Safety and Monitoring Committee (IDSMC).
    The end of trial is not defined as last visit of the last patient because there will still be data queries following this point.
