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   43851   clinical trials with a EudraCT protocol, of which   7283   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
    To evaluate the efficacy of 48-week study intervention with JNJ-3989+JNJ-6379+NA regimen compared to NA alone.
    Evaluar la eficacia del estudio de 48 semanas. Intervención con el tratamiento de JNJ-3989 + JNJ-6379 + AN en comparación con un AN en monoterapia
    E.2.2Secondary objectives of the trial
    1. To evaluate the safety and tolerability of the study intervention throughout the study.
    2. To evaluate the efficacy of the study intervention at the end of treatment.
    3. To evaluate the efficacy as measured by blood markers (such as HBsAg, HBV DNA, and ALT) during study intervention and follow-up.
    4. To evaluate the frequency of virologic breakthrough during study intervention.
    5. To evaluate the proportion of participants requiring NA re-treatment during follow-up.
    6. To identify baseline and on-treatment markers associated with sustained off-treatment response.
    7. To evaluate the PK of JNJ 3989 (JNJ-3976 and JNJ-3924), JNJ-6379, and NA, as applicable.
    1. Evaluar la seguridad y tolerabilidad de la intervención del estudio a lo largo del estudio.
    2. Evaluar la eficacia de la intervención del estudio al final del tratamiento.
    3. Evaluar la eficacia medida por los marcadores sanguíneos (como el HBsAg, el ADN del VHB y la ALT) durante la intervención y el seguimiento del estudio.
    4. Evaluar la frecuencia de los avances virológicos durante la intervención del estudio.
    5. Evaluar la proporción de participantes que requieren reanudación de tratamiento de NA durante el seguimiento.
    6.Identificar marcadores asociados a la respuesta sostenida sin tratamiento en el momento de referencia y durante el tratamiento.

    E.3Principal inclusion criteria
    M01/A01. Male or female participants ≥18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place) to ≤65 years of age.
    M02. Participant must be medically stable based on physical examination, medical history, vital signs, and 12-lead ECG performed at screening. If there are abnormalities, they must be consistent with the underlying illness in the study population. This determination must be recorded in the participant’s source documents and initialed by the investigator.
    M03/A02. Participants must have HBV infection documented by serum HBsAg positivity at screening. In addition, chronicity must be documented by any of the following at least 6 months prior to screening: serum HBsAg positivity, HBeAg or HBV DNA positivity, ALT elevation above ULN without another cause than HBV infection, documented transmission event, liver biopsy with changes consistent with chronic HBV, or should be documented by absence of marker for acute infection such as positive immunoglobulin M (IgM) anti-hepatitis B surface (HBs) and anti-HBc antibodies, which can be tested at screening.
    The participants should be virologically suppressed. They should:
    o Be HBeAg-negative,
    o Be on stable HBV treatment, defined as currently receiving NA treatment (ETV, TDF, or TAF) for at least 24 months prior to screening and having been on the same NA treatment regimen (at the same dose) as used in this study (see Section 6.1) for at least 3 months at the time of screening, AND
    o Have serum HBV DNA <60 IU/mL on 2 sequential measurements at least 6 months apart (one of which is at screening), AND
    o Have documented ALT values <2.0x ULN on 2 sequential measurements at least 6 months apart (one of which is at screening).
    M04. Participants must have a body mass index (weight in kg divided by the square of height in meters) between 18.0 and 35.0 kg/m2, extremes included.
