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   43841   clinical trials with a EudraCT protocol, of which   7281   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 ).

    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.
    Describir la FC de ENG y evaluar las concentraciones de estrona (E1) y estradiol (E2) en las usuarias del anillo vaginal de ENG-E2 para respaldar futuros análisis exploratorios de FC poblacional.

    Merck llevará a cabo investigaciones biomédicas futuras con las muestras obtenidas específicamente con estos fines durante este ensayo clínico. Estas investigaciones tendrán por objeto el análisis de biomarcadores para abordar aspectos nuevos que no se describen en otras partes del protocolo (como parte del ensayo principal) y solo se llevarán a cabo en muestras de los sujetos que hayan otorgado el consentimiento correspondiente. El objetivo de la obtención de muestras para investigaciones biomédicas futuras consiste en estudiar e
    identificar biomarcadores que proporcionen información a los científicos sobre las enfermedades y sus tratamientos. El objetivo último es utilizar tal información para desarrollar fármacos más seguros y eficaces y/o para garantizar que los pacientes reciban la dosis correcta del fármaco adecuado en el momento preciso.

    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
    El criterio de valoración principal de la eficacia para este ensayo es la determinación de la eficacia anticonceptiva (la evitación del embarazo durante el tratamiento) utilizando el IP, que se define como:
    IP= n/E,
    Donde n=número de embarazos durante el tratamiento, E= exposición en 100 años-mujer.
    El cálculo del intervalo de confianza del 95 % exacto para el IP se basará en la distribución de Poisson con las fórmulas [20]:
    -Límite inferior del IC del 95 % = (1/2E) x ji-cuadrado (0,025, 2n) y
    -Límite superior del IC del 95 % = (1/2E) x ji-cuadrado (0,975, 2n+2)
    (Ji-cuadrado = punto porcentual de la distribución de la ji al cuadrado).
    Si no se producen embarazos se utilizará un grado de confianza superior del 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.
    El IP se define como el numero de embarazos cada 100 mujeres-año que usan métodos anticonceptivos
    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).
    Los criterios de valoración principales de hemorragia vaginal para el ACC de las hemorragias vaginales son:
    -Incidencia de HMIM (es decir, cualquier episodio de hemorragia/manchado que se haya producido durante el intervalo de uso del anillo/toma de comprimidos, que no sea una HP prematura o continuada);
    -Incidencia de AHP (es decir, ningún episodio de hemorragia/manchado que haya comenzado o continuado durante el intervalo sin anillo o sin comprimidos).
    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 > or = to 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
    -Análisis secundario del PI - Estimación puntual junto con el IC del 95 % (18-35 años)
    -Análisis secundario del PI - Estimación puntual junto con el IC del 95 % (pacientes > o = a 18 años)
    -Incidencia de HMIM - Estimación puntual junto con un IC del 95 % (por ciclo de tratamiento)
    -Incidencia de AHP - Estimación puntual junto con un IC del 95 % (por ciclo de tratamiento)
