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   43851   clinical trials with a EudraCT protocol, of which   7283   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 primary objective of the study is to evaluate the dose-response of ACT-541468 on the change of Wake After Sleep Onset (WASO) assessed by polysomnography (PSG) on the first two days of each treatment period.
    Protection of trial subjects
    The study was conducted 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. Prior to the start of the study, each study site consulted an Independent Ethics Committee (IEC) or Institutional Review Board (IRB), i.e., a review panel that was responsible for ensuring the protection of the rights, safety and well-being of human subjects involved. The protocol and any material provided to the subject (such as a subject information sheet or description of the study used to obtain informed consent) were reviewed and approved by the appropriate IEC or IRB before the study was started. Prior to any study procedure, written informed consent was obtained from each participating subject. It was made clear to each subject that he or she was completely free to withdraw from it at any time for any reason.

    End point title
    		 Change in wake after sleep onset (WASO)
    End point description
    WASO is the time (min) spent awake after onset of persistent sleep until lights on, as determined by PSG. The change from baseline to Days 1&2 in WASO (min) was analyzed using the generalized MCP-Mod approach, which combines a Multiple Comparison Procedure (MCP) to assess the efficacy of ACT-541468 versus placebo followed by a modeling (Mod) step to characterize the dose-response relationship (see attachment). Modified full analysis set.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    10 Aug 2016
    One global amendment was issued to the original AC-078A202 protocol (dated 15 June 2016 ); this amendment (Global Amendment 1) was issued before enrolment of the first subject. Hence, all subjects were enrolled and treated under Global Protocol Version 2. Some changes: • The list of forbidden concomitant medications was modified (e.g. CYP3A4 substrates, inhibitors and inducers were added) • The list of inclusion/exclusion criteria was modified (e.g. subjects with severe renal impairment were not to be included) • The study-specific criteria for premature discontinuation of double-blind study treatment were defined • The sleep diary questionnaire was amended by two additional questions

    Interruptions (globally)
