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   43871   clinical trials with a EudraCT protocol, of which   7290   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 is to assess the efficacy of Bromelain tablets hysan® by the Total Rhinosinusitis Rescue Medication Score (TRSSRMS) taking in account the Rhinosinusitis Symptom Score (RSSS) of the four rhinosinusitis symptoms (nasal obstruction, nasal discharge, facial pain or facial pressure and reduction or loss of smell) and the Rescue Medication Score (RMS).
    Protection of trial subjects
    Three blood samples were taken, two of them in order to monitor clinical safety laboratory parameters. Beyond this no invasive interventions were undertaken. Patients were allowed to take the analgesic paracetamol in case of pain sensation and to use a decongesting nasal spray if necessary. Vital signs, physical findings and other observations related to safety were evaluated in the beginning and at the end of the trial.
    Background therapy
    Intake of paracetamol tablets and use of decongesting nasal spray (xylometazoline) were offered as rescue medication.

    Statistical analysis description
    The null hypothesis was that there is no difference in efficacy between the two treatment groups, i.e. placebo and Bromelain tablets hysan. The alternative hypothesis was that there is a verifiable therapeutic efficacy in the group treated with Bromelain tablets hysan with at least one difference to the placebo group. Differences between treatment groups were considered to be statistically significant at the 5 % level of significance using two sided tests.
