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   43977   clinical trials with a EudraCT protocol, of which   7312   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
    To evaluate the efficacy of a single, oral dose of S-033188 (baloxavir marboxil), compared with placebo by measuring the time to improvement of influenza symptoms in patients with influenza. Eligible patients were randomized in a 1:1:1 ratio to receive baloxavir marboxil or oseltamivir or placebo.
    Protection of trial subjects
    The study was conducted in accordance with the protocol approved by the IRBs/IECs, all applicable regulatory requirements, the current Good Clinical Practice (GCP) guidelines, all applicable patient privacy requirements, and the ethical principles that are outlined in the Declaration of Helsinki (1996).

    Recruitment
    Recruitment details
    		 A multicentre study conducted at 551 sites: included in Europe, USA, Japan, Asia Pacific and South Africa. Number of patients Consented: 2592 and Randomized: 2184 (730 in the baloxavir marboxil, 725 in the oseltamivir and 729 in the placebo groups respectively).

    Pre-assignment
    Screening details
    		 The study population composed of Male and female patients ≥ 12 years old with influenza A and/or B infection at high risk of developing influenza complications within 48 hours of symptom onset. Definition of high risk patients was adapted from the Centers for Disease Control and Prevention (CDC) criteria.

    Notes
    [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The number of subjects reported to have 'started' the "pre-assignment" period is the number that signed the Informed Consent Form prior to randomization. The number reported to have 'completed' is the number of patients that were randomized and is therefore, lower. Thus, the world-wide number reported is equal to the number of randomised patients and not to the pre-assignment number.

    Adverse events information
    Timeframe for reporting adverse events
    All Adverse Events (AEs) were collected from the time of informed consent through Visit 7 (Day 22). If a patient withdrew early from the study, the Investigator or sub-investigator made effort to collect AEs for 21 days after the last dose of study drug.
    Adverse event reporting additional description
    Adverse events were classified by System Organ Class (SOC) and Preferred Term (PT) using Medical Dictionary for Regulatory Activities (MedDRA). Adverse events reported after the initial dose of study drug were used for safety analyses. All AEs, including those occurring prior to the initiation of the study treatment, were listed.
