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   43861   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.3Principal inclusion criteria
    -Be ≥18 years of age on day of signing informed consent.
    -Have documented chronic (at least 6 months) HCV GT1 infection (with no evidence of non typable or mixed genotypes) :
    •Positive for anti-HCV antibody, HCV RNA, or an HCV genotype
    •HCV RNA (≥ 10,000 IU/mL in peripheral blood)
    -Have no evidence of cirrhosis based on the following:
    •Liver biopsy performed within 24 months of Day 1 of this study showing absence of cirrhosis
    •Fibroscan performed within 12 months of Day 1 of this study with a result of ≤12.5 kPa[54]*
    *Fibroscan cut-off of 12.5 kPa has a positive predictive value of 90% and a sensitivity of 95% for ≥F3. Based on box and whisker plot of interquartile distribution >12.5 kPa will exclude the majority of subjects with metavir F3 fibrosis
    •A FibroSure® (Fibrotest®) score of ≤0.48 and Aspartate Aminotransferase to Platelet Ratio Index (APRI) of ≤1 during Screening
    In the absence of a definitive diagnosis of presence or absence of cirrhosis by the above critieria, a liver biopsy is required. Liver biopsy results supersede the results obtained by Fibroscan or FibroSure®.
    -Have an HCV treatment status that is one of the following:
    Treatment naïve: Naive to all anti-HCV treatment
    Prior Treatment Relapse: Subjects relapsed after completing a prior course of HCV therapy that included IFN or PEG-IFN + Ribavirin but that did not include any direct acting antivirals.
    RELAPSE: HCV RNA undetectable (‘target not detected’) at end of treatment with a Peg-IFN containing regimen, but HCV RNA quantifiable (≥LLOQ) during follow-up
    -Have Chronic Kidney Disease defined as:
    Subjects with GFR ≤29 who are non-dialysis dependent (NDD) or have been on hemodialysis (HD) for at least 3 months (including subjects awaiting kidney transplant and subjects with failed kidney transplants no longer on immunosuppressant therapy).
    -Agree (if subject is of reproductive potential) to remain truly abstinent or use (or have their partner use) 2 acceptable methods of birth control from at least 2 weeks prior to Day 1 and throughout treatment, or longer if dictated by local regulations.
    If acceptable by local regulatory agencies, methods of birth control allowed in the study are: intrauterine device (IUD), diaphragm with spermicide, hormonal contraceptives (e.g., birth control pills, transdermal patch, or injectables), contraceptive sponge, female condom, male condom with spermicide or vasectomy.
    Note: Periodic abstinence (e.g., abstinence only on certain calendar days, abstinence only during ovulation period, use of symptothermal methods, use of post-ovulation methods and withdrawal) are not acceptable methods of contraception.
    -A female subject who is not of reproductive potential is eligible without requiring the use of contraception. A female subjects who is not of reproductive potentials is defined as one who has either 1) reached natural menopause (defined as 12 months with no menses without an alternative medical cause), 2) 6 weeks post surgical bilateral oophorectomy with or without hysterectomy, or 3) bilateral tubal ligation.
    -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.

    -The subject may also provide consent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research

    -Tener una edad mínima de 18 años el día de firma del consentimiento informado.

    •Positividad para anticuerpos anti-VHC, ARN del VHC o un genotipo del VHC.
    •ARN del VHC (≥ 10.000 UI/ml en sangre periférica).
    -No presentar datos de cirrosis basándose en lo siguiente:
    •Biopsia hepática practicada en los 24 meses anteriores al día 1 de este estudio que demuestre ausencia de cirrosis.
    •Fibroscan realizado en los 12 meses anteriores al día 1 de este estudio con un resultado ≤ 12,5 kPa [54]*.
    *El valor de corte del Fibroscan de 12,5 kPatiene un valor predictivo positivo del 90% y una sensibilidad del 95% para detectar una puntuación ≥ F3. Basándose en un gráfico de cajas y bigotes de la distribución intercuartílica, un valor> 12,5 kPa excluirá a la mayoría de los sujetos con una puntuación F3 de fibrosis Metavir.
    •Puntuación FibroSure® (Fibrotest®)≤ 0,48 e índice de aspartatoaminotransferasa/plaquetas (APRI) ≤ 1 durante la selección.
    Cuando no se disponga de un diagnóstico definitivo de presencia o ausencia de cirrosis basado en estos criterios, se necesitará una biopsia hepática.Los resultados de la biopsia hepática prevalecerán sobre los obtenidos con Fibroscan o FibroSure®.
