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   44334   clinical trials with a EudraCT protocol, of which   7366   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. be > or = to 18 years of age on day of signing informed consent.

    2. have a body weight > or = to 50 kg (111 lbs) and < or = to 125 kg (275 lbs).

    3. have chronic, compensated HCV GT 1a or GT 1b infection:
    -Positive serology for HCV with HCV RNA levels > or = to 10,000 IU/mL in peripheral blood at screening, and
    -Absence (no medical history or physical findings) of ascites, bleeding esophageal varices, hepatic encephalopathy, or other signs or symptoms of advanced liver disease, or cirrhosis.

    4. have had a liver biopsy without evidence of advanced fibrosis, cirrhosis and/or hepatocellular carcinoma. A liver biopsy done prior to screening is acceptable if it is performed:
    -Within 2 years of screening and the result was METAVIR (or equivalent) Stage 0 (F0) to 2 (F2).

    If the prior liver biopsy was obtained outside the acceptable windows, a repeat biopsy may be performed, and the results must show no evidence of advanced fibrosis, cirrhosis and/or hepatocellular carcinoma in order for the subject to be randomized in the study.

    For countries where liver biopsy is not performed prior to treatment and where noninvasive tests (for e.g. FibroScan and/or FibroTest) are used for staging of liver disease, these results may be used to assess eligibility. Subjects with a documented FibroScan score of < o = a 9.5 kPa, or FibroTest score of < o = a 0.58, are allowed to be enrolled in the study. These non-invasive tests done prior to screening are acceptable if they were performed within 1 year of screening and meet the indicated cut-offs. If the prior non-invasive tests were not performed within 1 year of screening, results from one of these non-invasive tests are required before study drug dosing. If a subject has both liver biopsy and one of these non-invasive tests, whichever test demonstrates the presence of advanced fibrosis or cirrhosis would be used to determine eligibility. In other words, if the liver biopsy shows advanced fibrosis or cirrhosis, the subject is excluded, regardless of results of the non-invasive assay. If the liver biopsy does not show advanced fibrosis or cirrhosis, but the non-invasive assay does, then the subject is excluded as well.

    5. agree to use two acceptable methods of birth control from at least 2 weeks prior to Day 1 and continue until at least 6 months after last dose of study drug, or longer if dictated by local regulations (for female subject who is of childbearing potential or male subject with female sexual partner who is of childbearing potential).

    If acceptable by local regulatory agencies, methods of birth control allowed in the study are: intrauterine device (IUD), diaphragm with spermicide, contraceptive sponge, female condom, male condom with spermicide, vasectomy, and true abstinence: Abstinence is in line with the preferred and usual lifestyle of the subject. [Periodic abstinence (e.g., abstinence only on certain calendar days, abstinence only during ovulation period, use of symptothermal method, use of post-ovulation methods) and withdrawl are not acceptable methods of contraception]. Hormonal contraceptives (e.g., birth control pills, transdermal patch, or injectables) are unacceptable methods of birth control for use in this study because it is not known whether these methods are affected by co-administration of MK-5172 and/or MK-8742.

    For the purposes of this protocol, a woman of non-childbearing potential is defined as one who has either 1) reached natural menopause (defined as 6 months of spontaneous amenorrhea with serum FSH levels in the postmenopausal range as determined by the laboratory, or 12 months of spontaneous amenorrhea), 2) 6 weeks post surgical bilateral oopherectomy with or without hysterectomy, or 3) bilateral tubal ligation.

    For the purposes of this protocol, a male subject who is not of reproductive potential is eligible without requiring the use of contraception. A male subject who is not of reproductive potential is defined as: one who has undergone a successful vasectomy. A successful vasectomy is defined as: (1) microscopic documentation of azoospermia, or (2) a vasectomy more than 2 years ago with no resultant pregnancy despite sexual activity post vasectomy.

    6. understand the study procedures, alternative treatments available, risks involved with the study, and voluntarily agrees to participate by giving written informed consent.

    7. Provide written informed consent/assent for the trial. The subject may also provide consent/assent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research.
    1.Edad mínima de 18 años el día de la firma del consentimiento informado.
    2.Peso corporal > o = a 50 y < o = a 125 kg.
    3.Presentar una infección crónica y compensada por el VHC de GT1a o GT1b:
    -Serología positiva para el VHC con una concentración de ARN del VHC > o = a 10.000 UI/ml en sangre periférica en el momento de selección y
    -Ausencia (sin antecedentes médicos ni hallazgos físicos) de ascitis, varices esofágicas hemorrágicas, encefalopatía hepática u otros signos o síntomas de hepatopatía avanzada o cirrosis.
    4.Haberse sometido a una biopsia hepática que no muestre signos de fibrosis avanzada, cirrosis ni carcinoma hepatocelular. Se aceptarán las biopsias hepáticas practicadas antes de la selección siempre que:
    -Se hicieran en los 2 años previos a la selección y el resultado fuera de estadio METAVIR (o equivalente) 0 (F0) a 2 (F2).
    Si la biopsia hepática previa se obtuvo fuera de los plazos aceptables, podrá repetirse y los resultados no podrán mostrar signos de fibrosis avanzada, cirrosis ni carcinoma hepatocelular para que el sujeto pueda ser aleatorizado en el estudio.
    En los países en que no se practique biopsia hepática antes del tratamiento y en los que se empleen pruebas no invasivas (por ejemplo, FibroScan o FibroTest) para estadificar la hepatopatía podrán utilizarse estos resultados para determinar la elegibilidad. Podrán participar en el estudio sujetos con una puntuación en el FibroScan documentada < o = a 9,5 kPa o una puntuación en el FibroTest < o 0 a 0,58. Estas pruebas no invasivas realizadas antes de la selección serán aceptables siempre que se efectuaran en el año anterior a la selección y que cumplan los límites indicados. Cuando las pruebas no invasivas precedentes no se hayan realizado en el año previo a la selección, se exigirán los resultados de una de estas pruebas no invasivas antes de la administración del fármaco del estudio. Si un sujeto cuenta con una biopsia hepática y una de estas pruebas no invasivas, el método que demuestre la presencia de fibrosis avanzada o cirrosis se utilizará para determinar la elegibilidad. En otras palabras, si la biopsia hepática revela fibrosis avanzada o cirrosis, se excluirá al sujeto, con independencia de los resultados de la prueba no invasiva. Si la biopsia hepática no revela fibrosis avanzada ni cirrosis, pero sí lo hace la prueba no invasiva, también se excluirá al sujeto.
    5.Comprometerse a utilizar dos métodos anticonceptivos aceptables desde al menos 2 semanas antes del día 1 y seguir utilizándolos hasta al menos 6 meses después de la última dosis del fármaco del estudio o durante más tiempo si así lo dictan las normativas locales (para las mujeres en edad fértil y los varones con parejas en edad fértil).
    Siempre que sean aceptables por las autoridades sanitarias locales, los métodos anticonceptivos permitidos en este estudio serán: dispositivo intrauterino (DIU), diafragma con espermicida, esponja anticonceptiva, preservativo femenino, preservativo masculino con espermicida, vasectomía y abstinencia real, cuando esté en consonancia con el modo de vida preferido y habitual del sujeto. [La abstinencia periódica (por ejemplo, abstinencia solo en determinados días, abstinencia solo durante el período de ovulación, uso del método sintotérmico o uso de métodos postovulación) y el coito interrumpido no serán métodos anticonceptivos aceptables]. Los anticonceptivos hormonales (por ejemplo, anticonceptivos orales, parches transdérmicos o inyectables) no serán aceptables en este estudio porque se ignora si resultan afectados por la administración concomitante de MK 5172 o MK 8742.
    En este protocolo, se considera que una mujer no tiene capacidad reproductiva si 1) ha alcanzado la menopausia natural (definida como 6 meses de amenorrea espontánea con concentraciones de FSH sérica en el intervalo posmenopáusico según lo determinado por el laboratorio o 12 meses de amenorrea espontánea); 2) se ha sometido a una ovariectomía bilateral con o sin histerectomía 6 semanas antes; o 3) se ha sometido a una ligadura de trompas bilateral.
    En este protocolo podrán participar varones sin capacidad reproductiva sin necesidad de utilizar métodos anticonceptivos. Los varones sin capacidad reproductiva son aquellos que se han sometido a una vasectomía eficaz. Una vasectomía eficaz se define como: 1) documentación microscópica de azoospermia o 2) vasectomía practicada más de 2 años antes sin embarazo resultante pese a mantener relaciones sexuales tras la vasectomía.
    6.Comprender los procedimientos del estudio, los tratamientos alternativos disponibles y los riesgos asociados y aceptar voluntariamente participar otorgando el consentimiento informado por escrito.
    7.Otorgar su consentimiento informado/asentimiento para el estudio. El sujeto también podrá otorgar su consentimiento/asentimiento para la investigación biomédica futura. No obstante, podrá participar en el ensayo principal sin necesidad de participar en la investigación biomédica futura.
