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   40115   clinical trials with a EudraCT protocol, of which   6570   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To determine the safety and tolerability of subjects with FM and moderate to severe renal dysfunction during 13 weeks of renally-adjusted dosing of DS-5565 compared to placebo, followed by a short-term (4-week) safety follow-up.
    Protection of trial subjects
    This trial was conducted in accordance with the ethical principles of Good Clinical Practice, according to the International Council for Harmonisation (ICH) Harmonised Tripartite Guidelines. An independent DSMB was created to further protect the rights, safety, and well-being of subjects who were participating in this study by monitoring their progress and results. The independent DSMB was composed of qualified scientists, who were not investigators in the study and not otherwise directly associated with the sponsor. Additional protection was provided by special monitoring of liver enzyme elevations and liver dysfunction performed by a Hepatic Adjudication Committee (HAC), which was comprised of three qualified hepatologists who also were not investigators in the study and not otherwise directly associated with the sponsor. The HAC completed assessments on an ongoing basis. Adjudication of hepatic events was based on evaluation of electronic case report forms (eCRFs) and source documents, as available, including but not limited to hospital discharge summaries, diagnostic imaging, histopathology, consultation, and laboratory reports.

    Recruitment
    Recruitment details
    Randomized patients were recruited in four countries: Bulgaria (5), Romania (3), Spain (1), and the United States (47).

    Pre-assignment
    Screening details
    Of 231 patients enrolled, 175 discontinued before being randomized.

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: Some patients who did not complete treatment per protocol were included in the safety follow-up.

    Number of patients experiencing a Treatment Emergent Adverse Event (TEAE) [1]
    End point description
    A TEAE is any adverse event that emerges on or after the first dosing of double blind study medication and during study treatment up to 4 weeks after the last dose of double blind study medication (having been absent prior to treatment) or worsens relative to the pre-double blind treatment state. Relationship of TEAEs to study drug was assessed by the investigator. Clinically significant changes from baseline in clinical laboratory evaluations, neurological examinations, and electrocardiograms are reported as TEAEs.
