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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Major Depressive Disorder is a chronic stress related disorder characterized by depressed mood and by vegetative and cognitive symptoms. Moreover, genetic, neuroendocrine and neurochemical biomarkers may predict impaired processing and regulation of emotions related to major depression as well as antidepressant treatment response in general. There is evidence, that the gut microbiome may influence stress, anxiety and depression-related behavior via effects on the host´s neuroendocrine system.
    Depression ist eine stressassoziierte Störung, charakterisiert durch gedrückte Stimmung, vegetative und kognitive Symptome. Außerdem könnten genetische, neuroendokrine, -chemische Biomarker Vorhersagen treffen über gestörte Verarbeitung/Regulation von Emotionen in Zusammenhang mit Depression sowie über das Ansprechen auf antidepressive Therapie. Es gibt Anhaltspunkte, dass das Dickdarm-Mikrobiom womöglich Einfluss hat auf Stress und Angst durch Effekte auf das neuroendokrine System des Wirtes.
    E.1.1.1Medical condition in easily understood language
    Disease characterized by depressed mood and by vegetative Symptoms (e.g. sleep disturbance, dimished appetite) and cognitive symptoms (e.g. reduced attention)
    Krankheitsbild charakterisiert durch gedrückte Stimmung, vegetative (z.B. Schlafstörungen, Appetitlosigkeit) und kognitive Symptome (z.B. Aufmerksamkeitsstörungen).
    E.1.1.2Therapeutic area Diseases [C] - Nervous System Diseases [C10]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Main issue:
    Are there different effects of Escitalopram, Mirtazapine and Agomelatine on the results of serially performed Dexamethasone/CRH tests, pharmaco-fMRI-scans and the microbiome composition in depressed patients within the framework of a week-long therapy? In this context, to what extent is there an interaction between the different systems?

    Hauptfragestellung:
    Gibt es unterschiedliche Effekte von Escitalopram, Mirtazapin und Agomelatin im Rahmen einer einwöchigen Therapie auf die Ergebnisse von seriell durchgeführten Dexamethason/CRH-Tests, Pharmako-fMRI-Scans und die Mikrobiomzusammensetzung bei depressiven Patienten? Inwieweit liegt hierbei eine Wechselwirkung zwischen den unterschiedlichen Systemen vor?

    E.2.2Secondary objectives of the trial
    Are possible effects of the investigational products on HPA axis activity in depressed patients related to the onset of antidepressant effectiveness or to the therapeutic response at the end of the treatment phase? Do depressive patients, who are showing an inhibition of cortisol levels in the Dex/CRH test after just one week, show an earlier response to the appropriate antidepressant?
    What changes in the pharmaco-fMRI-scan are associated with a therapeutic response in terms of a subsequent clinical improvement? Is it possible to predict the therapeutic response with the help of fMRI-scan and the specific changes in Week 1?
    What changes in the microbiome are associated with antidepressant effectiveness of the investigational products? Are these changes associated with a therapeutic response? What microbiome data can act as future biomarkers?
    As part of the planned experiment cells from the urine or the skin of healthy test subjects and patients with MDD are converted into neurons
    Stehen mögliche Effekte der Prüfpräparate auf die HHN-Achsenaktivität bei depressiven Patienten in Zusammenhang mit dem Beginn der antidepressiven Wirksamkeit oder dem therapeutischen Ansprechen am Ende der Behandlungsphase? Sprechen depressive Patienten die bereits nach einer Woche eine Inhibition der Cortisolwerte im Dex/CRH-Test zeigen früher auf das entsprechende Antidepressivum an?
    Welche Veränderungen im Pharmako-fMRI-Scan stehen im Zusammenhang mit einem therapeutischen Ansprechen im Sinne einer späteren klinischen Besserung? Kann man mittels fMRI-Scan und den spezifischen Veränderungen in Woche 1 das therapeutische Ansprechen vorhersagen?
    Welche Veränderungen im Mikrobiom stehen im Zusammenhang mit der antidepressiven Wirksamkeit der Prüfpräparate? Sind diese Veränderungen mit Therapieresponse assoziiert? Welche Informationen aus dem Mikrobiom können als zukünftige Biomarker fungieren
    Außerdem werden Zellen aus dem Urin/ Hautbiopsie gewonnen und zu Neuronen konvertiert

    E.5 End points
    E.5.1Primary end point(s)
    In this double-blind, placebo-controlled, parallel group study, 80 depressive patients will be randomly assigned to one of four tratment groups. This number seems necessary in order to attain a 60-Completer threshold, if we take into consideration the possible drop-out-rate. The 20 patients in each group receive either 10mg of Escitalopramn, 30mg of Mirtazapine, 25 mg of Agomelatine or a placebo-based treatment for at least seven days.
    The patients are administered the medicine as follows: Escitalopram at 08.00 hours, Mirtazapine or Agomelatine at 22.00 hours, in accordance with the usual clinical practice. For blinding purposes, the double-dummy-technique will be employed. In case of need, the patients in all treatment groups can be administered Lorazepam (up to 3mg/d), Zopiclon (up to 15mg/d) oder Zolpidem (up to 20mg/d).

    The following tables give an overview of the design of the study. The clinical trial period is planned to last two years.

    In diesem doppelblinden, Plazebo-kontrollierten, vierarmigen Studiendesign werden 80 depressive Patienten randomisiert einer von vier Behandlungsgruppen zugeteilt. Diese Anzahl scheint unter Berücksichtigung der möglichen Drop-out-Raten nötig, um mindestens 60 Completer zu erhalten. Die 20 Patienten jeder Gruppe enthalten entweder 10 mg Escitralopram, 30 mg Mirtazapin, 25 mg Agomelatin oder Plazebobehandlung für mind. sieben Tage. Die Patienten erhalten die Medikation wie folgt: Escitalopram 8 Uhr morgens, Mirtazapin oder Agomelatin um 10 Uhr abends, entsprechend der üblichen klinischen Vorgehensweise. Um die Verblindung zu gewährleisten wird die Double-Dummy-Technik verwendet. In allen Behandlungsarmen kann den Patienten bei Bedarf Lorazepam (bis zu 3mg/d), Zopiclon (bis zu 15mg/d) oder Zolpidem (bis zu 20mg/d) verabreicht werden. Einen Überblick über das Design der Studie geben die folgenden Auflistungen. Als Zeitrahmen für die klinische Prüfung sind zwei Jahre veranschlagt.

    E.5.1.1Timepoint(s) of evaluation of this end point
    On study day 11 (after seven days of treatment and the second fMRI scan) further treatment with antidepressants according to clinical requirements will follow.
    An Studientag 11 (nach 7 Behandlungstagen und dem zweiten fMRI-Scan) erfolgt eine weitere antidepressive Pharmakotherapie nach klinischem Ermessen.
    E.5.2Secondary end point(s)
    If no reduction of at least 20% in HAMD-21 scale is seen after 2 weeks of treatment, treatment according usual clinical requirements will be offered.
    Each patient will be advised independently of the study only according to clinical reasons. In case patients respond well to the treatment, it is considered to continue pharmacotherapy. In case of nonresponse other pharmacological and non-pharmacological interventions including augmentation strategies will be offered.
    Falls nach 2wöchiger Behandlung keine Reduktion von mind. 20% in der HAMD-21-Skala vorliegt, wird die Behandlung entsprechend den klinischen Erfordernissen umgestellt.
    Nachdem die Patienten die vorliegende Studie beendet haben, werden sie pharmakologisch nach Ermessen des behandelnden Arztes behandelt.
