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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    The objective of this extension study was to assess the long-term safety and tolerability of 10, 25 and 50 mg ACT‒541468 (daridorexant).
    Protection of trial subjects
    Sponsor personnel and the investigators were required to conduct the study in full compliance with ICH-GCP guidelines, the principles of the “Declaration of Helsinki”, and with the laws and regulations of the countries in which the study was conducted. Both the sponsor and the investigator had the right to terminate the study at any time, and in such a case, were responsible for protecting the subjects’ interests. The investigator was responsible for maintaining the subjects’ identities in strictest confidence. Written informed consent was obtained from each individual participating in the study prior to any study procedure and after adequate explanation of the aims, methods, objectives, and potential hazards of the study. It was made clear to each subject that he or she was completely free to refuse to enter the study, or to withdraw from it at any time for any reason. An Independent Data Monitoring Committee (IDMC) had overall responsibility for safeguarding the interests of subjects by monitoring, in an unblinded manner, safety and efficacy data obtained in the study and making appropriate recommendations based on the reported data, thus ensuring that the study was conducted to the highest scientific and ethical standards.

    Recruitment
    Recruitment details
    		 Ninety-four sites in 14 countries (Belgium, Bulgaria, Canada, Denmark, Finland, France, Germany, Hungary, South Korea, Poland, Spain, Sweden, Switzerland, and the US) enrolled and randomized subjects. Note: Subjects’ demographic and baseline characteristics were collected in the respective confirmatory study (ID-078A301 or 302).

    Pre-assignment
    Screening details
    		 Subjects assigned to the daridorexant arms in Study ID-078A301 and 302 received the same dose in the ID-078A303 extension study. Subjects assigned to the placebo arm in Study ID-078A301 and 302 were re-randomized to receive either placebo or 25 mg daridorexant in a 1:1 ratio, with treatment allocation stratified by age into two categories.

    Amendment
    04 Jul 2018
    It was clarified that subjects randomized to the placebo arm in ID-078A301 or ID-078A302 would be re-randomized to either placebo or daridorexant 25 mg in the ID-078A303 study in a 1:1 ratio, with treatment allocation stratified by age into two categories (< 65 and ≥ 65 years, as per the age entered at the screening visit in the ID-078A301 or ID-078A302 study).
    17 Feb 2020
    - The sponsor added an interim analysis for safety and efficacy to support regulatory filings, and an optional second interim analysis of safety if needed to fulfill health authority requirements. - It was clarified that, to maintain the integrity of the study after the interim analysis/analyses, participating subjects as well as investigators would remain blinded for the entire duration of the study. The sponsor personnel involved in data collection and medical monitoring of the extension study would also remain blinded until the end of the study. The sponsor made the following clarifications to endpoints: - Endpoints added for ESS, PGI-C and PGA-S. - Endpoint for subjective sleep efficiency removed. - C-SSRS© to be additionally analyzed for the placebo run-out period. - Rebound insomnia to be assessed with sTST only (sWASO and sLSO removed). - VAS scores for daytime alertness and daily ability to function to be analyzed as exploratory efficacy -endpoints instead of safety. - Endpoint added assessing the number (%) of subjects with ≥ 6 point decrease in ISI© total score from baseline.
