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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    Other types of substudies
    Specify title, date and version of each substudy with relative objectives: To describe the PK of ENG and assess the concentrations of estrone (E1) and estradiol (E2) in users of the ENG-E2 vaginal ring to support future exploratory population PK analyses.
    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.

    Altre tipologie di sottostudi
    specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: Descrivere la farmacocinetica di ENG e valutare le concentrazioni di estrone (E1) ed estradiolo (E2) in chi usa l¿anello vaginale ENGE2 per supportare le future analisi della PK.
    Merck condurr¿ una Ricerca Biomedica Futura su campioni di DNA (estratti dal sangue) raccolti nel corso di questo studio clinico.
    Tale ricerca ha lo scopo di esaminare vari biomarcatori per rispondere a domande che stanno emergendo e che non sono descritte in altre parti del protocollo (nell¿ambito dello studio principale), e verr¿ condotta solo su campioni di soggetti che
    abbiano rilasciato apposito consenso. L'obiettivo della raccolta dei campioni per la Ricerca Biomedica Futura ¿ quello di esplorare e identificare biomarcatori che contribuiscano scientificamente alla comprensione delle malattie e/o della relative terapie. L'obiettivo ultimo ¿ quello di utilizzare tali informazioni per sviluppare farmaci pi¿ sicuri e pi¿ efficaci, e/o per garantire che i soggetti ricevano la dose giusta del giusto farmaco al momento giusto.

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint for this trial is the determination of contraceptive efficacy (the prevention of in-treatment pregnancy) using the PI, as defined as follows:
    PI=n/E, Where n=number of in treatment pregnancies, E= exposure in 100 woman years. The calculation of the exact 95% confidence interval for the PI will be based on the Poissson distribution using the formulas: Lower limit 95% CI=(1/2/E) X chi square (0.025,2n), and Upper limit 95%CI= (1.2E) X chi square (.975,2n+2) (Chi-square = percentage point of the chi-square distribution)
    If no pregnancies occur an upper confidence level of 2.5% will be used.
    L’endpoint primario di efficacia di questa sperimentazione consiste nel determinare l’efficacia
    contraccettiva ( la prevenzione di una gravidanza durante il trattamento ) utilizzando l’Indice di Pearl (PI), così definito:
    PI=n/E
    Dove n= numero di gravidanze durante il trattamento, E= numero dei cicli mestruali incontrati dalla donna nello studio, poi moltiplicato per 1300 (100 womanyears).
    Il calcolo dell’ intervallo di confidenza (CI) al 95% per l’indice di Pearl, sarà basato sulla distribuzione di Poisson utilizzando la formula:
    Limite inferiore CI95% = (1/22/E)x chi quadro (0.025, 2n), e Limite superiore CI95% = (1.2E) x chi quadro (0.975n+2) (chi quadro:= punto percentuale della distribuzione chi quadro).
    Se non si verificano gravidanze, verrà utilizzato un livello superiore di confidenza pari al 2.5%.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The PI is defined as the number of pregnancies per 100 woman-years of a contraceptive method’s use.
    L’Indice di Pearl è definito come il numero di gravidanze sul numero dei cicli mestruali incontrati dalla donna che usa un metodo contraccettivo nello studio, poi moltiplicato per 1300 (100 woman-years).
    E.5.2Secondary end point(s)
    Main vaginal bleeding endpoints for the vaginal bleeding CCA are:
    - Incidence of BTB-S (any bleeding/spotting episode that occurred during the ring use tablet interval that
    is neither an early nor a continued.
    - Incidence of AWB (i.e. no bleeding/spotting episodes that began during or continued into the
    ring free interval or the tablet-free interval).
    Gli endpoint di efficacia secondari che saranno analizzati in un CCA sono i parametri associati
    all¿andamento del sanguinamento vaginale:
    - Incidenza di BTB-S per ciclo [ovvero qualsiasi episodio di sanguinamento/perdite manifestato durante il periodo di impiego dell¿anello/della pillola che non sia un sanguinamento precoce o un¿emorragia da sospensione (withdrawal bleeding, WB) continua]
    - Incidenza di AWB per ciclo di trattamento (ovvero nessun episodio di sanguinamento/perdite iniziato o continuato durante il periodo senza anello/pillola).
    E.5.2.1Timepoint(s) of evaluation of this end point
    For the Secondary analysis of the PI Point estimate along with the 95%CI (18-35 years) use of the supportive approach was done.
    - Secondary analysis of the PI ¿ Point estimate along with the 95% CI (subject > 18 years of age)
    - Incidence of BTB-S- point estimate along with 95% CI (per treatment cycle).
    - Incidence of absence of WB- point estimate along with 95% CI per treatment cycle P =Primary approach; S= secondary approach; CI= confidence interval BTB= break through bleeding.
    Per l¿analisi secondaria della stima puntuale dell¿indice di Pearl associato ad un intervallo di confidenza al 95% (18-35 anni), ¿ stato utilizzato un approccio di supporto all¿analisi primaria.
    - Analisi secondaria dell¿indice di Pearl - stima puntuale associata ad un intervallo di confidenza al 95% (soggetti >18 anni).
    - Incidenza di BTBS - stima puntuale associata ad un intervallo di confidenza al 95% (per ciclo di trattamento).
    - Incidenza dell¿assenza di WB - stima puntuale associata ad un intervallo di confidenza al 95% per ciclo di trattamento.
