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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main focus is to evaluate the impact of early interventional management of persistent AF.

    The primary goal is to evaluate if early pulmonary vein isolation performed with the Arctic Front cryoballoon as first-line therapy is superior to antiarrhythmic drugs (AAD) in preventing atrial arrhythmia recurrences.

    We hypothesized that first-line PVI using the cryoballon, at an early stage of the AF disease, will result in a 25 % reduction in any atrial tachyarrhythmia recurrence at 12 months compared to the AAD group
    Huvudfokus är att utvärdera effekten av tidig interventionshantering av ihållande förmaksflimmer (AF).

    Det primära målet är att utvärdera om tidig lungvensisolering (LVI) utförd med Arctic Front-kryoballongen som förstahandsbehandling är överlägsen antiarytmiska läkemedel (AAD) för att förhindra återfall av förmaksarytmi.

    Vår hypotes är att första handsbehandling med lungvensisolering med användning av kryoballon, i ett tidigt skede av AF-sjukdomen, kommer att resultera i en 25 % minskning av eventuella förmakstakyarytmier efter 12 månader jämfört med läkemedels-gruppen
    E.2.2Secondary objectives of the trial
    The secondary goal is to evaluate the impact of early invasive intervention on health related quality of life (HRQOL) and symptoms, and on safety in comparison to primary AAD therapy, using generic and disease-specific HRQOL questionnaires and also assess Quality Adjusted Life Years (QALYs) score and EHRA classification of symptoms.

    The third goal is to assess the impact of an early intervention on cardiovascular health care use (hospitalisations and other health care utilization) and its relation to AF burden and to assess treatment burden and cost-effectiveness compared to AAD.
    Det sekundära målet är att utvärdera effekten av tidig invasiv intervention på hälsorelaterad livskvalitet (HRQOL) och symtom, och på säkerheten i jämförelse med primär läkemedels-terapi, genom att använda generiska och sjukdomsspecifika HRQOL-enkäter och även bedöma kvalitetsjusterade levnadsår ( QALYs) poäng och EHRA-klassificering av symtom.

    Det tredje målet är att bedöma effekten av ett tidigt ablations ingripande på användningen av hjärt- och kärlvård (sjukhus och annan sjukvårdsanvändning) och dess relation till AF-bördan och att bedöma behandlingsbörda och kostnadseffektivitet jämfört med läkemedel.

    E.2.3Trial contains a sub-study Yes

    1. Total förmaksarytmibörda (% tid i AF/AT)
    2. AF-progression och -återgång mätt som en kombination av minskat antal AF-progressioner eller ökat antal AF-återvändningar efter 3 månaders blankning. Progression eller övergång till svårare AF-former såsom långvarig ihållande eller permanent AF och AF-regression som går i motsatt riktning från ihållande till paroxysmal till sinusrytm vid 12, 24 och 36 månader.
    3. Sjukvårdsanvändning av kardiovaskulära skäl (antal kardioversioner, ablationer, läkemedels-initieringar, kardiovaskulära sjukhusvistelser, akutmottagningsbesök och oplanerade polikliniska besök efter 3 månaders blankning) och dess relation till AF-börda. .
