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.

    Objectives:The DNA, serum, and plasma specimens collected in the current trial will be used to
    study various causes for how subjects may respond to a drug. The DNA, serum, and
    plasma specimens will be stored to provide a resource for future studies conducted by
    Merck focused on the study of biomarkers responsible for how a drug enters and is
    removed by the body, how a drug works, other pathways a drug may interact with, or

    Obiettivi:I campioni di DNA, siero e plasma raccolti nello studio in corso saranno utilizzati per
    studiare le varie cause di come i soggetti possono rispondere al farmaco. I campioni di DNA, siero e plasma saranno conservati per fornire una risorsa per futuri studi condotti da Merck, la quale è interessata allo studio dei biomarcatori responsabili di come un farmaco entra e si elimina dal corpo, di come un farmaco funziona, percorsi con cui un farmaco può interagire, o altri aspetti della malattia.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoints, primary analysis population, and statistical methods that will be employed for the efficacy analyses are presented in Table 2-5 Protocol page 33. The primary efficacy hypotheses will be evaluated by comparing sitagliptin vs. placebo on change from baseline in A1C at Week 16. No multiplicity adjustment is planned as there is a single comparison of 2 treatments using 1 endpoint in the primary hypothesis.
    Gli endpoints primari, la popolazione dell’analisi primaria e i metodi statistici che saranno adottati per le analisi di efficacia sono presentati nella Tabella 2-5 di pag 23 della Sinossi. Le ipotesi primarie di efficacia saranno valutate confrontando l’effetto di sitagliptin vs. placebo sulle variazoni dell’A1C rispetto al basale alla Settimana 16. Non è programmato alcun aggiustamento di molteplicità dato che si tratta di un unico confronto fra 2 trattamenti usando 1’endpoint nell’ipotesi primaria.

    16 settimane
    E.5.2Secondary end point(s)
    Other efficacy analyses will be considered supportive and/or explanatory. The placebo group in all analyses that involve between-group comparisons will pool both placebo treatment groups (i.e., placebo followed by sitagliptin and placebo followed by metformin).
    Le altre analisi di efficacia saranno considerate di supporto e/o esplicative. Il gruppo placebo in tutte le analisi che coinvolgono confronti fra i gruppi, raggrupperà entrambi i gruppi in trattamento con placebo (ossia, placebo seguito da sitagliptin e placebo seguito da metformina).
