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   43881   clinical trials with a EudraCT protocol, of which   7295   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 ).

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate efficacy and safety of an early switch to a two-drug regimen with DTG/3TC as single pill in participants who achieved and maintained a recent (less than 1 year) virological suppression with a three-drug INSTI-based ART, compared to continuing the INSTI-based three-drug first-line regimen. The primary analysis will be performed on the intention-to-treat (ITT) population as the proportion of participants with virologic rebound (one HIV-1 RNA ¿50 copies/mL) at Week 48 as defined by the US Food and Drug Administration (FDA) snapshot algorithm (non-inferiority margin 4%). An exploratory interim analysis will be performed after 50% of participants have completed 24 weeks of follow-up. After 48 weeks all the participants actively followed in the control group will switch to DTG/3TC as single pill (delayed switch), and the final evaluation will be performed after 96 weeks.
    Valutare l’efficacia e la sicurezza di uno switch precoce ad un regime a due farmaci con DTG/3TC associati in una singola compressa, in partecipanti che hanno raggiunto recentemente (< di 1 anno) una soppressione virologica stabile con una ART contenente INSTI a tre farmaci, rispetto alla prosecuzione del regime di prima linea a tre farmaci contenete INSTI. L’analisi primaria sarà condotta su tutta la popolazione dei pazienti trattati (analisi intention-to-treat (ITT)) nella quale l’efficacia sarà valutata come proporzione di partecipanti con rebound virologico (HIV-1 RNA>50 copie/mL) alla settimana 48 come definito dall’algoritmo US FDA Snapshot .Un’analisi ad interim esplorativa verrà eseguita dopo che il 50% dei partecipanti avrà completato 24 settimane di follow-up. Dopo 48 settimane tutti i partecipanti attivamente seguiti nel gruppo di controllo passeranno al regime sperimentale (DTG/3TC in singola compressa), e la valutazione finale sarà eseguita dopo 96 settimane.
    E.2.2Secondary objectives of the trial
    To evaluate safety and tolerability of the two strategies over time;
    • To evaluate immunologic response and dysfunction (CD4+ and CD8+ absolute counts and percentage; CD4+/CD8+ ratio) in both arms;

    • To detect resistance-associated mutations (in integrase and reverse transcriptase) in participants with PDVF by means of a next generation sequencing assay detecting minority species at >1% prevalence
    • To evaluate the effects of the two strategies on fasting lipids (TC, LDL, HDL non-HDL, TC/ HDL) over time
    • To evaluate adherence levels to ARVs in both arms
    • To evaluate neuropsychiatric symptoms in both arms
    • Valutare la sicurezza e la tollerabilità delle due strategie nel tempo;
    • Valutare la risposta immunologica (conta assoluta e percentuale di CD4+ e CD8+; CD4+/CD8+ ratio) in entrambi i bracci;

    • Rilevare mutazioni associate a resistenza (in integrasi e trascrittasi inversa) in partecipanti con PDVF mediante il test next generation sequencing assay che rileva le specie minoritarie con una prevalenza >1%;
    • Valutare nel tempo l’effetto delle due strategie sul profilo lipidico (TC, LDL, HDL non-HDL, TC/ HDL);
    • Valutare i livelli di aderenza alla ARV in entrambi i bracci;

    E.5 End points
    E.5.1Primary end point(s)
    Proportion of participants with virological rebound (viral load =50 copies/mL or premature discontinuations, irrespective of reason, with last viral load =50 copies/mL) at week 48. The novel primary end point will be evaluated according to the FDA snapshot algorithm primary efficacy endpoint in virologically suppressed participants. The primary end point will be estimated according to an ITT approach in which all randomized participants will be included. The sample size has been calculated on this end point according to a non-inferiority design, with a non-inferiority margin of 4%.
    • A preliminary interim analysis will be performed after 50% of the enrolled participants will have reached the 24th week of study.
    • At 48 weeks, a secondary analysis will be performed according to a per protocol (PP) approach. In this case only participants fulfilling protocol-defined timeline and continuing to take the randomized therapy will be considered.
    • After 48 weeks, all participants will receive DTG/3TC (delayed switch) and a final evaluation will be performed at week 96. The exploratory analyses at Week 96 will take place after the last subject has completed 100 weeks on therapy (in arm B), as needed, to allow for the collection of a confirmatory viral load measurement in subjects presenting with HIV-1 RNA =50 copies/mL at Week 96.
    • Proporzione di partecipanti con rebound virologico (carica virale =50 copie/mL o interruzioni anticipate, indipendentemente dalla ragione, con ultima carica virale =50 copie/mL) alla settimana 48. L’end point primario sarà valutato secondo l’end point di efficacia dell’algoritmo snapshot FDA nei partecipanti con soppressione virologica. L’end point primario sarà stimato secondo un approccio ITT nel quale saranno inclusi tutti i partecipanti randomizzati. La dimensione campionaria è stata calcolata su questo end point in accordo al disegno di non-inferiorità, con un margine di non inferiorità del 4%.
    • Una preliminare analisi ad interim sarà eseguita dopo che il 50% dei partecipanti arruolati avrà raggiunto la 24° settimana di studio.
    • A 48 settimane, sarà eseguita un’analisi secondaria secondo un approccio per protocollo (PP). In questo caso saranno considerati solo i pazienti partecipanti che soddisfano la timeline definita da protocollo e che continuano la terapia.
    • Dopo 48 settimane, tutti I partecipanti riceveranno DTG/3TC (delayed switch) e una valutazione finale sarà eseguita alla settimana 96. Le analisi esplorative alla settimana 96 si svolgeranno dopo che l’ultimo paziente ha completato 100 settimane di terapia (nel braccio B), per consentire la misurazione di conferma della carica virale in soggetti che presentano alla settimana 96 HIV-1 RNA =50 copie/mL.

    • Viral minority variants harboring resistance associated mutations (to any drug class) at the time of PDVF will be characterized in plasma or in proviral DNA (in case of low viremia levels, <200 copies/mL) by next generation sequencing. For the minority resistant variants detected (prevalence >1%), their resistance viral burden will be also evaluated.
    • Clinical and laboratory safety parameters; a descriptive analysis of all reported AEs and a quantitative analysis of AEs leading to treatment interruption/change will be used to evaluate long-term tolerability of the simplification treatment.
    • Changes in fasting lipids (TC, LDL, HDL, non-HDL, TC/HDL) from baseline to w48 and 96.
    • Absolute changes as well as proportion of participants above clinically relevant thresholds will be used to evaluate the change of metabolic parameters over time.

Per le varianti di resistenza minoritarie rilevate sarà valutato anche il loro impatto sulla resistenza virale.
    • Parametri di sicurezza clinica e di laboratorio; un’analisi descrittiva di tutti gli AEs segnalati e un’analisi quantitativa dei AEs che portano all’interruzione/modifica del trattamento saranno utilizzati per valutare la tollerabilità a lungo termine del trattamento di semplificazione.
