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   44313   clinical trials with a EudraCT protocol, of which   7357   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.5 End points
    E.5.1Primary end point(s)
    The primary endpoint for intervention 1 (with or without doxycycline PEP) is the first episode of chlamydia or syphilis after the enrolment visit (J0DV) (chlamydia and syphilis diagnosed at the enrolment visit will not be included in the primary endpoint).
    The primary endpoint for intervention 2 (with or without Bexsero® vaccine) is the first episode of gonorrhea reported one month after the second vaccine injection, so starting at the month 3 visit (gonorrhea episodes diagnosed at the enrolment visit and before the month 3 visit will not be included in the primary endpoint).
    In these analyses, subject follow-up will be right-censored at the time of the first STI.
    Le critère principal de jugement de l'intervention 1, doxycycline en PEP ou pas de PEP, est le premier épisode de syphilis ou de chlamydia déclaré après la visite d’inclusion J0DV (les infections par syphilis et chlamydia diagnostiquées à J0DV ne seront pas prises en compte pour le critère principal de jugement).
    Le critère principal de jugement de l'intervention 2, vaccin Bexsero® ou absence de vaccin, est le premier épisode de gonorrhée déclaré un mois après la deuxième injection, c’est-à-dire à partir de la visite M3DV (les infections à gonocoques diagnostiquées entre J0DV et la visite M3DV ne seront pas prises en compte pour le critère principal de jugement).
    Dans ces analyses, le suivi du sujet sera censuré au moment de la première IST.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Intervention 1 : the date of the first episode of syphilis or chlamydia after the enrolment visit (J0DV)
    Intervention 2 : the date of the first episode of gonorrhea reported one month after the second vaccine injection
    Intervention 1 : date du premier épisode de syphilis ou chlamydia après la visite d’inclusion (J0DV)
    Intervention 2 : date du premier épisode de gonorrhée reporté un mois après la seconde vaccination
    E.5.2Secondary end point(s)
    The following secondary criteria will be compared between the treatment arms:
    1- Occurrence of a first episode of each of the bacterial STIs as well as cumulative incidence of each bacterial STIs (syphilis, chlamydia; gonorrhoea and Mycoplasma genitalium) during the trial. In that case, the entire follow-up will be considered.
    2- Occurrence of a new episode of anal or urinary gonorrhoea.
    3- Occurrence of a first symptomatic episode of chlamydia infection or gonorrhea at urinary or anal sites.
    4- Impact of doxycycline PEP on the human microbiota: detection from throat swab of carriage of Methicillin-Resistant Staphylococcus aureus (MRSA) and/or doxycycline resistant Staphylococcus aureus, fecal carriage of Extended Spectrum Beta-Lactamase (ESBL)-producing Enterobacteriaceae, and composition of the intestinal microbiota).
    5- Safety and adherence to PEP.
    6- Antibiotic susceptibilities of all strains of NG, CT, MG to doxycycline, macrolides, fluoroquinolones and third generation cephalosporin for gonorrhea or TP PCR-positive samples with and without PEP.
    7- Rate of cured STIs after treatment with or without PEP.
    8- Composition of the resistome and clonality of Neisseria gonorrhoeae strains with or without doxycycline.
    9- Serum bactericidal activity against meningococcal and gonococcal antigens over time in participants of Bexsero®’s arm.
    10- Safety of Bexsero® vaccine.
    11- Prevalence and incidence of meningococcal carriage in pharyngeal, anal and urine swabs.
    12- Impact of PEP or Bexsero® vaccine on sexual behaviour (rates of condom use for receptive anal intercourse, number of sexual partners and number of sex acts over time).
    13- Incidence of HIV infection with both prophylaxis strategies.
    Les critères secondaires suivants seront comparés entre les bras de traitement :
    1- La survenue d'un premier épisode de chacune des IST bactériennes ainsi que l'incidence cumulée de chaque IST bactérienne (syphilis, chlamydia, gonorrhée et Mycoplasma genitalium) au cours de l'étude. Dans ce cas, la totalité du suivi sera prise en compte.
    2- La survenue d'un nouvel épisode de gonorrhée anale ou urinaire.
    3- La survenue d’un premier épisode symptomatique de gonorrhée ou d’infection à chlamydiae anale ou urinaire.
    4- L’évaluation de l'impact de la doxycycline administrée en PEP sur le microbiote humain : détection à partir du prélèvement de gorge de Staphylococcus aureus résistant à la méthicilline (SARM) et/ou de Staphylococcus aureus résistants à la doxycycline et sur le portage fécal d'entérobactéries productrices de bêta-lactamase à spectre étendu (BLSE) et l’étude de la composition du microbiote intestinal (étude ancillaire « microbiote intestinal » 30 participants dans le centre de l'Hôpital Saint-Louis).
    5- La tolérance et l’observance de la PEP avec doxycycline.
    6- La sensibilité aux antibiotiques de toutes les souches de Neisseria gonorrhoeae (NG), de Chlamydia trachomatis (CT), et l’absence ou la présence de mutations associées à la résistance à la doxycycline dans les échantillons Mycoplasma genitalium (MG) ou Treponema pallidum (TP)-PCR positifs avec ou sans doxycycline en PEP.
