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   43844   clinical trials with a EudraCT protocol, of which   7282   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.

    General information about the trial
    Main objective of the trial
    To compare the efficacy of EMA401 vs. placebo in 24-hour average pain intensity score at Week 12, using an 11-point Numeric Rating Scale (NRS) by testing the superiority of EMA401 100 mg b.i.d. vs. placebo
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.

    Notes
    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: All subjects who completed the double-blind treatment period did not enter the treatment withdrawal period

    The BPI-SF is a validated, self-administered (at clinic) questionnaire that assesses pain severity and its mpact on daily functions. Patients were asked to complete the 7-item pain interference scale that assessed the degree to which pain interfered with walking and other physical activity, work, mood, relations with others and sleep using a zero to ten numeric rating scale (NRS) with zero being "does not interfere" and ten being "completely interferes".

    		 Mean change in Insomnia Severity Index (ISI) from Baseline to Week 12
    End point description
    Patients were asked to complete the ISI using five-point Likert-style scale as a measure of perceived sleep difficulties. Scores ranged from zero to 28, with a cut-off score of eight suggesting the presence of sub-threshold insomnia. The questionnaire assessed the severity of insomnia, satisfaction with current sleep pattern, sleep interference, "noticeability" of sleeping problem to others and concern about sleeping problems.

    		 Plasma Pharmacokinetics (PK) Concentrations at Week 8 and 12 [3]
    End point description
    Due to the premature termination of the study, the number of patients and observations providing PK data was much smaller than planned, and no PK model was developed. As a consequence, no PK parameters (Cmax, Tmax, AUC) were derived for this study. Only, summary statistics of the plasma concentrations were calculated

    [3] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
