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   43889   clinical trials with a EudraCT protocol, of which   7298   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.3Principal inclusion criteria
    1.End-stage renal disease (ESRD) subjects who have been on HD for at least 3 months and are currently on HD at least 3 times per week. Subjects with or without associated pruritus may enroll.
    2.Males or females 12 to 17 years of age, at the time of consent.
    3.Has a prescription dry body weight =20 kg and =100 kg

    2. Soggetti di sesso maschile o femminile di età compresa fra 12 e 17 anni al momento del consenso.
    3. Soggetti con un peso corporeo secco prescritto =20 kg e =100 kg.
    E.4Principal exclusion criteria
    1.Known to be non compliant with HD treatments and deemed unlikely to complete the study by the Investigator (i.e., has a history of missed HD sessions due to non adherence in the past 2 months).
    2.Planned or anticipated to receive a kidney transplant during the study. Note: Being on a kidney transplant list is not an exclusion criterion.
    3.Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) greater than 2.5 × the reference upper limit of normal (ULN), or bilirubin greater than 4 × the ULN at screening.
    4.Subject has known hypersensitivity to the study drug or any components of the difelikefalin formulation.
    5.Known history of allergic reaction to opiates such as hives. Note: Side effects related to the use of opioids such as constipation or nausea would not exclude the subjects from the study.
    6.Previous participation in this study.
    7.Known or suspected history of alcohol, narcotic, or other drug abuse or substance dependence within 12 months prior to screening.
    8.Acute or unstable medical condition(s) which in the opinion of the Investigator would pose undue risk to the subject or would impede complete collection of evaluable data.
    1. Nota mancata compliance ai trattamenti di HD e improbabilità che lo studio sia completato secondo il giudizio dello Sperimentatore (ovvero, anamnesi di sessioni di HD saltate per mancata aderenza negli ultimi 2 mesi).
    2. Trapianto di rene pianificato o previsto durante lo studio. Nota: Essere in lista per un trapianto di rene non costituisce criterio di esclusione.
    3. Alanina aminotransferasi (ALT), aspartato aminotransferasi (AST) nel siero superiori a 2,5 volte il limite superiore della norma (ULN) o bilirubina superiore a 4 x ULN allo screening.
    4. Soggetto con ipersensibilità nota al farmaco in studio o a qualsiasi componente della formulazione di difelikefalin.
    5. Anamnesi nota di reazione allergica agli oppiacei, ad esempio orticaria. Nota: Gli effetti collaterali associati all'uso di oppioidi come la costipazione o la nausea non escluderebbero i soggetti dallo studio.
    6. Precedente partecipazione a questo studio
    7. Anamnesi nota o sospetta di abuso di alcol, narcotici o altre droghe o dipendenza da sostanze nei 12 mesi precedenti lo screening.
    8. Condizioni mediche acute o instabili che, secondo il giudizio dello Sperimentatore, comporterebbero un rischio eccessivo per il soggetto o impedirebbero la raccolta completa di dati valutabili
