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   43881   clinical trials with a EudraCT protocol, of which   7295   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 determine the ratio of parent drug to metabolites in the circulation. Profiling of [14C]-etripamil metabolites in blood, urine and feces. To determine the mass balance of drug-related materials following intranasal administration. To determine the primary route of excretion of drug-related materials. To determine the total radioactivity versus time profile in plasma and whole blood.
    Protection of trial subjects
    To safeguard the study subjects and the site staff, testing for COVID-19 was performed. A SARS-CoV-2 PCR was performed on nasal and/or throat swabs. The testing was performed one day prior to the scheduled study admittance day of the treatment period (Day -2). An extra residence day and night in the clinic was added for the treatment period where subjects came in one day prior to the scheduled study admittance day.
