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   43857   clinical trials with a EudraCT protocol, of which   7284   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 ).

    General information about the trial
    Main objective of the trial
    The main objective of the trial was to assess the safety and efficacy of repeat applications of Qutenza TM (Capsaicin (8%) high-concentration patch) over 52 weeks in participants with Peripheral Neuropathic Pain (PNP).
    Protection of trial subjects
    This clinical study was written, conducted and reported in accordance with the protocol, ICH GCP Guidelines, and applicable local regulations, including the European Directive 2001/20/EC, on the protection of human rights, and with the ethical principles that have their origin in the Declaration of Helsinki.Astellas ensures that the use and disclosure of protected health information (PHI) obtained during a research study complies with the federal, national and/or regional legislation related to the privacy and protection of personal information. Approval for the study protocol, dated 30 Apr 2010, was obtained from the relevant competent authorities prior to study initiation.
    Background therapy
    Participants receiving first patch application could receive oral and transdermal opioid medication if it did not exceed a total oral daily dose of morphine of 80 mg or the equivalent, which was to be calculated using the Opioid Equivalence Guidance. Any changes, additions or discontinuations to medications were assessed and recorded at every study visit. A short acting opioid could be administered to relieve treatment-associated discomfort during and/or after treatment procedures, while the patient was in the clinic. Participants could receive concomitant systemic non-opioid pain medications for the treatment of Peripheral Neuropathic Pain(PNP).

    Neurological Assessment (SAF)
    End point description
    An abbreviated neurological examination was performed at the screening visit, at all patch application visits, at week 26 visit (if applicable), and at the planned or early termination visit. It included assessments of gait, muscle strength, and reflexes. The assessments were classified as normal, abnormal-not clinically significant and abnormal-clinically significant. Endpoint of interest was the number and percentage of participants with each neurological assessment score at the different study time points.

    Responses to BPI Question 5 (average pain) were recorded daily and weekly (± 2 days) from the 1st patch application until the planned or early termination visit. Weekly response was recorded on the day chosen by patient during the 1st patch application visit (± 2 days). Each BPI item uses a 0 to 10 rating scale anchored at zero for“no pain”and 10 for “pain as bad as you can imagine” for severity and “does not interfere” to “completely interferes” for interference.

    Tolerability of patch application (SAF)
    End point description
    Analyses of tolerability include summaries of the percent of intended patch application time overall and by patients’ individual neuropathic diagnosis. Duration of patch application was the difference between the stop and start times, and it was presented as a percentage of intended patch application duration. The proportion of patients completing at least 90% of the intended patch application were reported at each patch application. Additionally, a patient was deemed to have had an early patch removal if they had an AE with study drug action of temporary discontinuation, if the patch application duration was less than 100%, or if the patient went on to receive additional subsequent patch applications.

    Change from Baseline HADS (Hospital Anxiety and Depression Scale)(SAF)
    End point description
    The HADS is a self-report scale developed for the assessment of anxiety and depression in non-psychiatric populations. In this study it was used to screen for the presence of moderate to severe depressive symptomatology and to assess co-morbid depression during the course of the study. It contains 14 items rated on a 4-point Likert-type scale. There are 2 sub-scales, one assessing depression and the other anxiety. The 7-item depression and anxiety subscales yield scores of 0 to 21 that are interpreted with the following cut-off points: 0 to 7, normal; 8 to 10, mild mood disturbance; 11 to 14, moderate mood disturbance; and 15 to 21, severe mood disturbance. Full Analysis Set (FAS) was used for analysis and data presented represents change from baseline.

    Self-assessment of Treatment (SAT) (SAF)
    End point description
    Participants answered a SAT questionnaire at week 26 (if applicable) and the planned or early termination visit. The SAT assesses treatment satisfaction by using a 5-point Likert-type scale ranging from -2 (a strong negative response) to 2 (a strong positive response); zero indicates a neutral response. The questionnaire contains each of the following questions: 1. How do you assess your pain level after treatment in this study? 2. How do you assess your activity level after treatment in this study? 3. How has your quality of life changed after treatment in this study? 4. Would you undergo this treatment again? 5. How do you compare the treatment you received in this study to previous medication or therapies for your pain?. Data was represented by counts in combined categories [Worse: (-2) + (-1)] [Not Better or Worse: (-2) + (-1) + (0)] and [Better: (1) + (2).

    Adverse events information
    Timeframe for reporting adverse events
    Adverse Events (AEs) are summarized as counts over the entire study and by patch application. Within each of these time periods AEs are summarized overall and by individual neuropathic diagnosis. Only TEAEs were analyzed in this study.
    Adverse event reporting additional description
    Each AE was categorized based on which patch applications it occurred between (i.e.,between 1st and 2nd, between 2nd and 3rd, etc., or after last). Each AE was additionally categorized based on whether it occurred within 7 days after a patch application, and also based on whether it occurred more than 7 days after a patch application.
