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   44334   clinical trials with a EudraCT protocol, of which   7366   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.5 End points
    E.5.1Primary end point(s)
    Primary estimands supporting the primary objective are defined as:
    Population: separate assessment for participants with CHB on stable nucleos(t)ide therapy and participants with CHB not currently on nucleos(t)ide therapy.
    Variable: Sustained virologic response for 24 weeks after the end of GSK3228836 treatment in the absence of rescue medication.
    Treatments: arms 1, 2, & 3. Estimation of the within-arm response rate.
    Intercurrent events: use of rescue medication and discontinuation of/interruption of/adherence to IP. The use of rescue medication has been incorporated into the definition of variable (composite strategy). Discontinuation of, interruption of, and adherence to IP will be ignored (treatment policy). Wide disruptive events preventing assessment of primary outcome will be handled assuming they had not happened (hypothetical strategy)
    Population summary: proportion of participants who achieve SVR for each treatment arm.
    The primary estimands for each sub-population is the proportion of participants in each treatment arm 1, 2, & 3 who achieve SVR for 24 weeks after the end of GSK3228836 treatment in the absence of rescue medication regardless of completing IP, interruptions in IP or adherence to IP had they not been affected by wide disruptive events.
    I valori stimati primari a supporto dell’obiettivo primario sono definiti come:
    - Popolazione: valutazione separata per quanto segue:
    • partecipanti con CHB in terapia nucleotidica/nucleosidica stabile
    • partecipanti con CHB attualmente non in terapia nucleotidica/nucleosidica.
    - Variabile: risposta virologica sostenuta (SVR, descritta nella sezione 9.4.2.) per 24 settimane dopo la conclusione del trattamento con GSK3228836 in assenza di farmaci di salvataggio.
    - Trattamenti: bracci 1, 2 e 3. Stima del tasso di risposta all’interno del braccio.
    - Eventi intercorrenti: uso di farmaci di salvataggio e sospensione/interruzione di/aderenza all’IP. L’uso di farmaci di salvataggio è stato incorporato nella definizione di variabile (strategia composita). La sospensione, l’interruzione e l’aderenza all’IP saranno ignorate (politica di trattamento). Eventi eccezionali di grande portata (quali la pandemia di COVID-19) che impediscano la valutazione dell’outcome primario saranno gestiti supponendo che non si siano verificati (strategia ipotetica)
    - Riepilogo della popolazione: percentuale di partecipanti che raggiungono la SVR per ciascun braccio di trattamento.
    Il valore stimato primario per ciascuna sottopopolazione è la percentuale di partecipanti in ciascun braccio di trattamento 1, 2 e 3 che raggiungono la SVR per 24 settimane dopo la conclusione del trattamento con GSK3228836 in assenza di farmaci di salvataggio, indipendentemente dal completamento dell’IP, dalle interruzioni dell’IP o dall’aderenza all’IP se non fossero stati influenzati da eventi eccezionali di grande portata.

    Weekly during the treatment period (Day 1 to Day 162; with additional visits for loading dose on Day 4 and Day 11) and then decrease in frequency during the off-treatment period (8 visits over 24 weeks; Off-treatment weeks: Off treatment week 1, week 2, week 4, week 8, week 12, week 20, and week 24)
    Settimanalmente durante il periodo di trattamento (da Giorno 1 a Giorno 162; con visite addizionali per le dosi di carico al Giorno 4 e al Giorno 11) e poi una riduzione della frequenza durante il periodo di post trattamento (8 visite nell'arco di 24 settimane; Settimane fuori trattamento: fuori trattamento settimana 1, settimana 2, settimana 4, settimana 8, settimana 12, settimana 20, e settimana 24)
    E.5.2Secondary end point(s)
    1) Categorical Variables:
    -Achieving HBsAg <LLOQ and HBV DNA <LLOQ at the end of treatment.
    -Categorical changes from baseline in HBsAg (e.g., <0.5, =0.5, =1, =1.5, =3 log10 IU/mL) and in HBV DNA (e.g., <1, =1, =2, =3 log IU/mL)
    -ALT normalization over time in absence of rescue medication
    - Population summary: proportion of participants in each category for each treatment arm.
    2) Continuous Variables: Actual values and change from baseline over time of HBsAg and HBV DNA and actual values and change from baseline of HBeAg levels; HBs antibody (anti-HBsAg) and HBe antibody (anti-HBeAg) levels; Time to ALT normalization
    - Population summary: mean values and mean changes from baseline for each variable in each treatment arm
    1) Variabili categoriali:
    - Ottenimento di HBsAg <LLOQ e DNA dell’HBV <LLOQ alla conclusione del trattamento.
    - Variazioni categoriali rispetto al basale di HBsAg (ad es. <0,5, =0,5, =1, =1,5, =3 log10 UI/mL) e del DNA dell’HBV (ad es. <1, =1, =2, =3 log UI/mL)
    - Normalizzazione dell’ALT (ALT=ULN) nel tempo in assenza di farmaci di salvataggio nei partecipanti con ALT>ULN al basale
    - Riepilogo della popolazione: percentuale di partecipanti in ciascuna categoria per ciascun braccio di trattamento.
    2) Variabili continue: valori effettivi e variazione nel tempo rispetto al basale di HBsAg e del DNA dell’HBV, e valori effettivi e variazione rispetto al basale dei livelli di HBeAg; livelli di anticorpi HBs (anti-HBsAg) e HBe (anti-HBeAg)
    - Riepilogo della popolazione: valori medi e variazioni medie rispetto al basale per ogni variabile in ciascun braccio di trattamento.
