Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   38177   clinical trials with a EudraCT protocol, of which   6271   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).

    General information about the trial
    Main objective of the trial
    To evaluate the safety and efficacy of eculizumab in transfusion-dependent patients with haemolytic paroxysmal haemoglobinuria (PNH).
    Protection of trial subjects
    Patients must have been vaccinated for Neisseria meningitidis 14 days prior to randomisation.
    Background therapy
    No background therapy used.
    Evidence for comparator
    This was a randomised, double-blind, placebo-controlled, multicenter study. The use of a placebo-controlled group was deemed appropriate for this trial because the standard of care applicable at the time of study initiation for PNH (eg, transfusions or other symptomatic treatment measures) was permitted to be used in conjunction with proposed study therapy. Thus, patients were not placed at undue risk and patients may have benefited by increased monitoring of physical signs and symptoms during the study.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: A total of 114 patients were screened, 109 patients were enrolled in the observation period, and 87 entered treatment phase (treatment period). The baseline period was considered to be at time of entry into the actual treatment period.

The scoring guideline for the FACIT-Fatigue scale version 4 instrument was used to calculate the QoL score; per the corresponding scoring guideline, scores can range from 0 to 52, with higher scores indicating improvement in fatigue. A minimally important difference was defined as a change of 4 or more points at 26 weeks (Visit 18).

    Information regarding AEs was collected from the time the patient signed the informed consent form up to 30 days after the last dose of investigational product was administered.
    Adverse event reporting additional description
    At every visits, patients were asked a standard non-leading question to elicit any changes in their medical well-being including inquiry about any hospitalization, accidents and new/changed concomitant medication regimens. AEs were documented from any data collected (e.g. laboratory values, physical examination findings, ECG changes, etc.)
