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   43858   clinical trials with a EudraCT protocol, of which   7284   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 Objective of the trial
    E.2.1Main objective of the trial
    In pediatric patients (ages 10-17 years) with T2DM with inadequate glycemic control on
    metformin monotherapy:
    1. Objective: After 20 weeks, to assess the effect of the addition of sitagliptin compared
    with the addition of placebo on A1C.
    Hypothesis: The addition of sitagliptin reduces A1C more than the addition of
    placebo after 20 weeks of treatment.
    2. Objective: To assess the safety and tolerability of the addition of sitagliptin.
    In pazienti pediatrici (10-17 anni di età) con T2DM e inadeguato controllo glicemico in
    monoterapia con metformina:
    1. Obiettivo: Dopo 20 settimane per valutare l’effetto sulla A1C dell’aggiunta di sitagliptin
    rispetto all’aggiunta di placebo.
    Ipotesi: L’aggiunta di sitagliptin riduce la A1C più dell’aggiunta del placebo dopo 20
    settimane di trattamento.
    2. Obiettivo: Valutare la sicurezza e la tollerabilità dell’aggiunta di sitagliptin.
    E.2.2Secondary objectives of the trial
    In pediatric patients (ages 10-17 years) with T2DM with inadequate glycemic control on
    metformin monotherapy, after 20 weeks:
    1. Objective: To assess the effect of the addition of sitagliptin compared with the
    addition of placebo on fasting plasma glucose (FPG).
    2. Objective: To assess the effect of the addition of sitagliptin compared with the
    addition of placebo on the proportion of patients requiring glycemic rescue therapy.
    In pazienti pediatrici (10-17 anni di età) con T2DM e inadeguato controllo glicemico in
    monoterapia con metformina dopo 20 settimane:
    1. Obiettivo: Valutare l’effetto dell’aggiunta di sitagliptin rispetto all’aggiunta di placebo
    sulla glicemia a digiuno (fasting plasma glucose) (FPG).
    2. Obiettivo: Valutare l’effetto dell’aggiunta di sitagliptin rispetto all’aggiunta di placebo
    sulla percentuale di pazienti che richiedono la terapia di salvataggio glicemico.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Title (Titolo, in inglese): Future Biomedical Research
    Objectives (Obiettivi, in inglese): 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 other aspects of disease.
    Titolo: Ricerca Biomedica Futura
    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 efficacy hypothesis will be evaluated by comparing the addition of
    sitagliptin vs. placebo on change from baseline in A1C at Week 20 using an analysis of
    covariance (ANCOVA) model. The ANCOVA model will include terms for treatment
    and stratum, and covariates for baseline BMI SD score and baseline A1C.
    L’ipotesi primaria di efficacia sarà valutata confrontando l’effetto dell’aggiunta di sitagliptin
    vs. placebo sulle variazioni dell’A1C rispetto al basale alla Settimana 20, usando un modello
    di analisi di covarianza (ANCOVA). Il modello ANCOVA includerà i termini per il
    trattamento e lo strato, e le covariate per il punteggio BMI SD al basale e l’A1C al basale.
