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   43839   clinical trials with a EudraCT protocol, of which   7280   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
    The aim of the trial is to investigate whether treatment with Low dose Naltrexone (LDN) has a superior effect compared with placebo on pain in female patients with fibromyalgia, evaluated after 12 weeks of treatment.
    E.2.2Secondary objectives of the trial
    Our key secondary efficacy objectives will be to compare the effect of drug LDN, relative to placebo, on (i) global assessment and on (ii) changes in pain, (iii) tenderness, (iv) fatigue, (v) sleep disturbance, (vi) depression, (vii) anxiety, (viii) cognition, (ix) stiffness, (x) physical function, (xi) quality of life and (xii) pain distribution from baseline to week 4, 8 and 12, in female patients with fibromyalgia. Furthermore, responder indices will be compared between the treatment groups.

    Among the exploratory secondary objectives are changes in muscle exhaustion, physical fitness, pain sensitivity, inhibition of pain, augmentation of pain, and pro- or anti-inflammatory cytokines.

    E.5 End points
    E.5.1Primary end point(s)
    Average pain during the last 7 days. Change from baseline when assessed after 12 weeks of treatment with LDN or LDN-placebo.
    Assessed by asking the participants about the level of average pain during the last 7 days on a 11 point rating scale, ranging from 0-10 (0 = "no pain" and 10 = "unbearable pain") using the first item from the symptom part of the Fibromyalgia Impact Questionnaire Revised.
    E.5.1.1Timepoint(s) of evaluation of this end point
    After 12 weeks of treatment
    E.5.2Secondary end point(s)
    The secondary outcomes include 21 supportive measures that will be collected, analyzed and reported in the primary manuscript.

    For the following secondary outcomes, the between-group change at baseline compared to 4, 8 and 12 weeks of treatment is assessed:
    1. Global assessment. Assessed by Patient Global Impression of Change on a 1-7 Verbal Rating Scale.
    2. Impact of fibromyalgia. Assessed by the FIQR total score (22).
    3. Pain distribution. Assessed by the Widespread Pain Index (WPI) from the 2016 diagnostic criteria for fibromyalgia (23).
    4. Level of pain (assessment of pain intensity trajectory). Assessed by the FIQR "level of pain" question.
    5. Level of tenderness. Assessed subjectively by the FIQR "level of tenderness to touch" question and assessed objectively by measurement of pressure pain threshold, using a handheld algometer.
    6. Level of fatigue. Assessed by the FIQR "level of energy" question.
    7. Level of sleep disturbance. Assessed by the FIQR "quality of sleep" question.
    8. Level of depression. Assessed by the FIQR "level of depression" question.
    9. Level of anxiety. Assessed by the FIQR "level of anxiety" question.
    10. Level of cognition. Assessed by the FIQR "level of memory problems" question.
    11. Level of stiffness. Assessed by the FIQR "level of stiffness" question.
    12. Level of physical function. Assessed by the physical function domain of FIQR.
    13. Health-related quality of life – mobility. Assessed by the European Quality of Life 5 Dimensions (EQ-5D) mobility domain.
    14. Health-related quality of life - self-care. Assessed by the EQ-5D self-care domain.
    15. Health-related quality of life - usual activities. Assessed by the EQ-5D usual activities domain.
    16. Health-related quality of life - pain/discomfort. Assessed by the EQ-5D pain/discomfort domain.
    17. Health-related quality of life - anxiety/depression. Assessed by the EQ-5D anxiety/depression domain.
    18. Health-related quality of life – global. Assessed by European Quality of Life Visual Analogue Scale (EQ-VAS).

    Responder indices:
    19. Number of responders with a more than 15% improvement of the primary outcome.
    20. Number of responders with a more than 30% improvement of the primary outcome.
    21. Number of responders with a more than 50% improvement of the primary outcome.
