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   43857   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.

Sexually active females of child bearing potential must agree to comply with any applicable contraceptive requirements of the protocol. If male, must agree to use an acceptable method of birth control, as defined in the protocol, during the study treatment administration period and for 90 days afterward if treated with maribavir, ganciclovir, valganciclovir, or cidofovir and for 180 days afterward if treated with foscarnet.
    10.Be able to swallow tablets
    11.Be willing and have an understanding and ability to fully comply with study procedures and restrictions defined in the protocol
    12.Be willing to provide necessary samples (eg, biopsy) for the diagnosis of tissue invasive CMV disease at baseline as determined by the investigator
    13.Life expectancy of ≥8 weeks
    1. Ser capaces de otorgar su consentimiento informado por escrito, firmado personalmente y fechado, para participar en el estudio antes de realizar ninguno de los procedimientos relacionados con el estudio. Si procede, uno o ambos progenitores o el representante legal del sujeto deberán otorgar su consentimiento informado firmado, además de quedar constancia del asentimiento del sujeto, antes de realizar ninguno de los procedimientos relacionados con el estudio.
    2. Ser receptores de un trasplante de células pluripotenciales hematopoyéticas o de órgano sólido.
    3.

    E.4Principal exclusion criteria
    1.Have a current CMV infection that is considered refractory or resistant due to inadequate adherence to prior anti-CMV treatment, to the best knowledge of the investigator
    2.Requires ganciclovir, valganciclovir, foscarnet, or cidofovir administration for conditions other than CMV when study treatment is initiated (example: herpes simplex virus (HSV) coinfection requiring use of any of these agents after the randomization) or would need a coadministration with maribavir for CMV infection
    (example: intraocular administration of ganciclovir for CMV retinitis). NOTE: A subject who is not continuing with the same anti-viral drug(s)(ganciclovir, valganciclovir, or foscarnet) for the study must discontinue their use before the first dose of study drug. If subject is currently being treated with cidofovir and is assigned another anti-CMV agent by the investigator, the subject must discontinue its use at least 14 days prior to randomization at Visit 2/Day 0 and the first dose of study treatment.
    3.Be receiving leflunomide, or artesunate when study treatment is initiated. NOTE: Subjects who may be receiving leflunomide must discontinue the use at least 14 days prior to randomization at Visit 2/Day 0 and the first dose of study treatment. Subjects receiving artesunate must discontinue the use prior to the first dose of
    study treatment.
    4.Have severe vomiting, diarrhea, or other severe gastrointestinal illness within 24 hours prior to the first dose of study treatment that would preclude administration of oral/enteral medication
    5.Have known hypersensitivity to the active substance or to an excipient for a study treatment
    6.Have tissue invasive CMV disease with central nervous system involvement
    7.Serum aspartate aminotransferase (AST) >5 times upper limit of normal (ULN) at screening, or serum alanine aminotransferase (ALT) >5 times ULN at screening, or total bilirubin ≥3.0 x ULN at screening (except for documented Gilbert’s syndrome), by local or central lab. NOTE: Subjects with biopsy confirmed CMV hepatitis will not be excluded from study participation despite AST or ALT >5 times ULN at screening.
    8.Have positive results for human immunodeficiency virus (HIV). Subjects must have a confirmed negative result within 3 months of study entry or be willing to be tested at screening. Local laboratory results are acceptable.
    9.Require mechanical ventilation or vasopressors for hemodynamic support at the time of enrollment
    10.Be female and pregnant or breast feeding
    11.Have previously received maribavir
    12.Have received any investigational agent with known anti-CMV activity within 30 days before initiation of study treatment or investigational anti-CMV vaccine at any time
    13.Have active malignancy with the exception of nonmelanoma skin cancer. Subjects who have had a HSCT and who experience relapse or progression of the malignancy, as per investigator’s opinion are not to be enrolled.
    14.Undergoing treatment for acute or chronic hepatitis C
    15.Have any clinically significant medical or surgical condition that, in the investigator’s opinion, could interfere with the interpretation of study results, contraindicate the administration of the assigned study treatment, or compromise the safety or well-being of the subject
    1. Tener una infección por CMV que se considere refractaria o resistente debido a un cumplimiento deficiente del tratamiento previo contra el CMV, hasta donde sepa el investigador.
    2. Requerir la administración de ganciclovir, valganciclovir, foscarnet o cidofovir por enfermedades distintas del CMV cuando se inicie el tratamiento del estudio (por ejemplo, coinfección por el virus del herpes simple (VHS) que requiera el uso de cualquiera de estos fármacos después de la aleatorización) o con necesidad de administración conjunta con maribavir por la infección por CMV (por ejemplo, administración intraocular de ganciclovir por una retinitis por CMV). NOTA: Los sujetos que no vayan a continuar con el mismo antiviral (ganciclovir, valganciclovir o foscarnet) durante el estudio deberán suspender su uso antes de la primera dosis del fármaco del estudio. Si un sujeto está recibiendo tratamiento con cidofovir en ese momento y el investigador le asigna un fármaco contra el CMV diferente, deberá suspender su uso al menos 14 días antes de la aleatorización en la visita 2/día 0 y la primera dosis del tratamiento del estudio.
    3. Estar recibiendo leflunomida o artesunato cuando se inicie el tratamiento del estudio. NOTA: NOTA: Los sujetos que estén recibiendo leflunomida deberán suspender su uso al menos 14 días antes de la aleatorización en la visita 2/día 0 y la primera dosis del tratamiento del estudio. Los sujetos que estén recibiendo artesunato deberán suspender su uso antes de la primera dosis del tratamiento del estudio.
    4. Tener vómitos o diarrea intensos o algún otro trastorno gastrointestinal grave en las 24 horas previas a la primera dosis del tratamiento del estudio que impidan la administración de medicación oral/enteral.
    5. Tener hipersensibilidad conocida al principio activo o a un excipiente del tratamiento del estudio.
    6. Presentar enfermedad por CMV con invasión tisular con afectación del sistema nervioso central.
    7. Tener una concentración sérica de aspartato aminotransferasa (AST) > 5 veces el límite superior de la normalidad (LSN) en la selección, de alanina aminotransferasa (ALT) > 5 veces el LSN en la selección o de bilirrubina total ≥ 3,0 veces el LSN en la selección (salvo síndrome de Gilbert documentado), según el laboratorio local o central. NOTA: no se excluirá de la participación en el estudio a los sujetos con hepatitis por CMV confirmada mediante biopsia, a pesar de que presenten valores de AST o ALT > 5 veces el LSN en la selección.
    8. Estar infectados por el virus de la inmunodeficiencia humana (VIH). Los sujetos deberán tener un resultado negativo confirmado en los 3 meses previos a la incorporación al estudio y estar dispuestos a someterse a análisis en la selección. Serán aceptables los resultados de un laboratorio local.
    9. Necesitar ventilación mecánica o vasopresores para apoyo hemodinámico en el momento de inclusión.
    10. Estar embarazadas ni en período de lactancia.
    11. Haber recibido maribavir con anterioridad.
    12. Haber recibido cualquier fármaco en investigación con actividad conocida contra el CMV en los 30 días previos al comienzo del tratamiento del estudio o una vacuna en investigación contra el CMV en cualquier momento.
    13. Tener una neoplasia maligna activa, a excepción de un cáncer de piel distinto del melanoma. No se podrá incluid a los sujetos que hayan recibido un TCPH y experimenten recidiva o progresión de la neoplasia maligna, según el criterio del investigador.
    14. Estar en tratamiento por una hepatitis C aguda o crónica.
    15.
