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   43851   clinical trials with a EudraCT protocol, of which   7283   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
    The following applies to Part A and Part B (unless otherwise specified):
    1. To evaluate the efficacy of the combination regimens of MK-5172 and MK-3682 (300 mg or 450 mg) with either MK-8742 (Part A only) or MK-8408 (Parts A and B) as assessed by the proportion of subjects in each arm achieving SVR 12 (Sustained Virologic Response 12 weeks after the end of all study therapy), defined as HCV RNA <LLOQ (either TD[u] or TND) 12 weeks after the end of all study therapy.
    2. To evaluate the safety and tolerability of the combination regimens of MK-5172 and MK-3682 (300 mg or 450 mg) with either MK-8742 (Part A only) or MK-8408 (Parts A and B) to subjects in each arm.
    Quanto segue è applicabile alla Parte A e alla Parte B (se non diversamente specificato):
    1. valutare l'efficacia dei regimi di MK-5172 e MK-3682 (300 mg o 450 mg) in combinazione con MK-8742 (solo Parte A) o con MK-8408 (Parte A e B) valutata in base alla proporzione di soggetti che raggiunge l’SVR12 (risposta virologica sostenuta, 12 settimane dopo la conclusione di tutte le terapie dello studio), definita come HCV-RNA< limite minore di rilevamento (LLOQ lower limit of quantitation) (TDu Target Detected but unquantifiable o TND Target Not Detected) 12 settimane dopo la conclusione di tutte le terapie in studio.
    2. valutare la sicurezza e la tollerabilità dei regimi di MK-5172 e MK-3682 (300 mg o 450 mg) combinati o con MK-8742 (solo Parte A) o con MK-8408 (Parte A e B) nei soggetti in ogni braccio.
    E.2.2Secondary objectives of the trial
    1. To evaluate the efficacy of the combination regimens of MK-5172 and MK-3682 (300 mg or 450 mg) with either MK-8742 (Part A only) or MK-8408 (Parts A and B) as assessed by the proportion of subjects in each arm achieving SVR 4 (Sustained Virologic Response 4 weeks after the end of all study therapy), defined as HCV RNA <LLOQ (either TD(u) or TND) 4 weeks after the end of all study therapy.
    In Part B, the secondary objectives above will be evaluated within each subject population (HIV/HCV co-infected vs. mono-infected, and cirrhotic vs. non-cirrhotic) separately. In addition, the following objectives will also be evaluated for the HIV co-infected population:
    2. to evaluate the proportion of subjects who develop HIV-1 virologic failure (HIV-1 RNA 200 copies/mL, confirmed on two consecutive tests at least 2 weeks apart, in subjects compliant with their HIV antiretroviral therapy [ART]).
    3. to evaluate the effect of the study regimens on CD4+ T-cell counts.
    1. valutare l'efficacia dei regimi delle combinazioni di MK-5172 e MK-3682 (300 mg o 450 mg), o con MK-8742 (solo Parte A) o con MK-8408 (Parte A e B), in base alla proporzione di soggetti in ciascun braccio che raggiunge l’SVR4 (risposta virologica sostenuta, 4 settimane dopo la conclusione di tutte le terapie in studio), definita come HCV-RNA< limite minore di rilevamento (LLOQ lower limit of quantitation) (TDu Target Detected but unquantifiable o TND Target Not Detected) 4 settimane dopo la conclusione di tutte le terapie in studio.
    Nella Parte B saranno valutati anche i seguenti obiettivi per la popolazione con co-infezione da HIV:
    2. Valutare la proporzione di soggetti nei quali si verifica fallimento virologico per HIV-1 (HIV-1 RNA di 200 copie/ml, confermato con due esami consecutivi effettuati a distanza di almeno 2 settimane, in soggetti che si attengono alla loro terapia antiretrovirale per HIV [ART]).
    3. Valutare l'effetto dei regimi in studio sulla conta di T-cellule CD4
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    1)FBR:Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.2) Intensive Viral Kinetic Sub-study, a subgroup of the study population will be included in an intensive viral kinetic sub-study. The purpose of this sub-study is to determine whether early viral kinetics can aid in developing a PK/PD model that can predict combinations which may be efficacious with shorter treatment durations.These subjects will have HCV RNA samples collected during Week 1 as described in the Study Flow Chart (Section 6.0) and in Table 15(Intensive Viral Kinetic Week 1 Sampling Timepoints). In addition, PKsamples will be collected as described in Table 13 (PharmacokineticSampling Timepoints). These samples will be used to evaluate thePK/PD relationships of MK-5172, MK-3682 (and metabolites), MK-8742,and MK-8408, as appropriate.
    1.Merck condurrà una Ric Biom Fut su campioni di DNA(estratti dal sangue)raccolti nel corso di questo studio clinico.Tale ricerca ha lo scopo di esamin vari biomarc per risp a domande che stanno emergendo e che non sono descritte in altre parti del prot(nell’ambito dello studio principale),e verrà condotta solo su campioni di sogg che abbiano rilasciato apposito consenso.L'obiett della raccolta dei camp per la Ric Biom Fut è quello di esplorare e identificare biomarc che contribuiscano scientific alla comprensione delle malattie e/o della relative terapie.L'obiett ultimo è quello di utilizzare tali info per sviluppare farmaci più sicuri e più efficaci, e/o per garantire che i sogg ricevano la dose giusta del giusto farmaco al momento giusto.2.Un sottogruppo della popol in studio sarà incluso in un intens sotto-studio di cinetica virale.Lo scopo di questo sotto-studio è quello di determinare se le cinetiche virali iniziali possono essere d'aiuto nello sviluppo di un modello PK/PD capace di predire combinaz che potrebbero essere efficaci in trattamenti di più breve durata.I campioni di HCV RNA saranno raccolti da questi sogg durante la sett1 come descritto nel diagr di flusso dello studio e nella Tab15(Intensive Viral Kinetic Week 1 Sampling Timepoints).Inoltre, saranno raccolti campioni per PK come descritto in Tab13(Pharmacokinetic Sampling Timepoints). Questi camp saranno utilizzati per valutare i rapporti di di MK5172, MK3682(e metaboliti), MK8742 e MK8408,ove appropriato
