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.2.1Main objective of the trial
    Demonstrate the efficacy of AXA1665 compared to placebo on neurocognitive function as assessed by the PHES over 24 weeks in cirrhotic subjects with a prior history of OHE.
    Dimostrare l’efficacia di AXA1665 rispetto al placebo sulla funzione neurocognitiva, valutata mediante il punteggio psicometrico dell’encefalopatia epatica (Psychometric Hepatic Encephalopathy Score, PHES) nell’arco di 24 settimane nei soggetti con cirrosi e una precedente anamnesi di encefalopatia epatica conclamata (Overt Hepatic Encephalopathy, OHE).
    E.2.2Secondary objectives of the trial
    • Safety and tolerability of AXA1665;
    • Changes in other cognitive function measures (Stroop Off+On time via the Stroop EncephalApp);
    • Impact on OHE recurrence as assessed by the total number of OHE breakthrough events, time to first OHE breakthrough event, and hospitalizations for OHE-related events;
    • Impact on all-cause hospitalizations;
    • Impact on physical function as assessed by the LFI and HR-QoL measures (Patient-Reported Outcomes Measurement Information System [PROMIS] Physical Function Short Form 8b); and
    • Changes in other general HR-QoL measures (PROMIS-29), caregiver burden (Zarit Burden Interview), and falls.
    • Sicurezza e tollerabilità di AXA1665;
    • Variazioni in altre misure della funzione cognitiva (tempo di attivazione e disattivazione tramite Stroop EncephalApp);
    • Impatto sulla recidiva dell’OHE, valutato in base al numero totale di eventi di comparsa dell’OHE, al tempo al primo evento di comparsa e ai ricoveri correlati all’OHE;
    • Impatto sui ricoveri per qualsiasi causa;
    • Impatto sulla funzione fisica valutato mediante l’indice di debolezza del fegato (LFI) e le misure della qualità della vita correlata alla salute (HR-QoL) (Modulo breve 8b del Sistema informativo per la misurazione degli esiti riferiti dal paziente [PROMIS] sulla funzione fisica); e
    • Variazioni in altre misure generali della HR-QoL (PROMIS-29), nel carico per l’accompagnatore (Zarit Burden Interview) e nelle cadute.

    4. Absence of OHE at both Screening and prior to randomization, as assessed by a standardized questionnaire administered by the Investigator to assess alertness, orientation, and OHE medication use;
    Note: If OHE is present at or after Screening and prior to randomization, the subject will be withdrawn; however, they may be rescreened after their active OHE episode has resolved and may be allowed to participate in the study provided they satisfy the eligibility criteria.

    8. Support of a primary caregiver for the entire duration of the study and the identified primary caregiver is able and willing to give written informed consent. The identified primary caregiver must be willing to assist with assessing the subject's level of alertness, orientation, filling out diaries, and attending scheduled and unscheduled study visits; to observe any changes in the subject's health; and to remind the subject to take the study drug;
    9. Willing to comply with specified procedures as stated in the protocol;
    10. Agrees to abstain from alcohol consumption for the duration of the study, from Screening through the final study visit;
    11. Negative urine ethyl glucuronide at Screening;
    Note: If the subject's urine ethyl glucuronide is positive during the course of the study, it would lead to the subject's withdrawal from the study.
    12. Negative urine screen for drugs of abuse or legal substance abuse, including recreational marijuana, at Screening;
    13. If a subject is female, 1 of the following criteria must be met;
    • Surgically sterile;

    2.Anamnesi di cirrosi e almeno 1 precedente episodio documentato di OHE nelle 24 settimane precedenti lo screening;
    Nota: la documentazione relativa all’OHE deve essere resa disponibile e contenere informazioni sufficienti, affinché lo sperimentatore possa confermare in modo indipendente una diagnosi clinica di OHE (ad es. le cartelle cliniche o il riepilogo delle dimissioni) e i trattamenti somministrati per quell’episodio di OHE (ad es. lattulosio/lattitolo somministrato con o senza rifaximina).
