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   43602   clinical trials with a EudraCT protocol, of which   7206   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
    The project aims to improve the fertility potential for patients operated
    in early infancy for bilateral cryptorchidism but still having a high risk of
    infertility due to an underlying endocrinopathy. Furthermore, the aim of
    the study is to show that this selected group of bilateral cryptorchid boys
    with high risk of infertility, despite early surgery for undescended testes,
    will benefit from adjuvant postoperative hormone therapy and in case of
    treatment failure to rescue germ cells by cryopreservation, while germ
    cells are still present in the undescended testes.
    Projektet sigter mod at forbedre fertilitetspotentialet hos patienter, der
    opereres i den tidlige spædbarn for bilateral kryptorchidisme, men som
    stadig har en høj risiko for infertilitet på grund af en underliggende
    endokrinopati. Endvidere er formålet med undersøgelsen at vise, at
    denne udvalgte gruppe af bilaterale cryptorchid-drenge med stor risiko
    for infertilitet, på trods af tidlig kirurgi for ubesværede testikler, vil
    drage fordel af adjuvans postoperativ hormonbehandling og i tilfælde af
    behandlingssvigt med at redde kimceller ved kryopræservering , mens
    kimceller stadig er til stede i de uanfægtede testikler.

    E.3Principal inclusion criteria
    Bilateral cryptorchidism in 52 boys from 6 to 36 months of age at time of surgery. The germ cell number per tubular transverse section in testicular biopsies should be mean 0.2 to 0.5 and PLAP (placental alkaline phosphatase) positive germ cells should be present. The estimation of germ cell count is performed according to a method from our laboratory previously published . Serum levels of FSH and LH must not be increased above normal range .
    Bilateral kryptorchidisme hos 52 drenge fra 6 til 36 måneders alder på
    operationstidspunktet. Kimcelleantallet pr. Rørformet tværsnit i
    testikulære biopsier skal være middel 0,2 til 0,5, og PLAP (placental
    alkalisk phosphatase) positive kimceller skal være til stede. Skøn over
    antallet af kimceller udføres efter en metode fra vores tidligere
    publicerede laboratorium . Serumniveauer af FSH og LH må ikke øges
    over det normale område .
    E.4Principal exclusion criteria
    Another significant abnormality or earlier inguinal operation.
    Anden betydelig abnormalitet eller tidligere operation i lysken
    E.5 End points
    E.5.1Primary end point(s)
    Evaluation: The effect of gonadotropin therapy is estimated by
    evaluation of the testis histopathology, estimation of the number of
    germ cells per tubular transverse section, presence of adult dark
    spermatogonia and hormone profile by 9 - 12 months of follow-up.
    Success criteria include the normalization of the germ cell number with
    significant increase in the kryptocur® group compared to the placebo
    group, presence of adult dark spermatogonia and normal serum inhibin-
    9 - 12 måneder efter primær-operationen tilbydes både
    hormonbehandlede og placebogruppen, ny hormonprofil, ny vævsprøve
    og nedfrysning af testikelvæv med henblik på eventuel senere
    fertilitetsbehandling (behandling af forplantningsevnen hvis
    hormonbehandlingen har været utilstrækkelig). Der foretages blindet
    evaluering af kønscelle status og hormonstatus. Herefter brydes koden
    og patienter der har fået placebo tilbydes aktiv behandling.
    Evaluering: Resultatet af hormon-behandlingen bedømmes ud fra
    evaluering af vævsundersøgelsen af testiklerne (stenene) og
    hormonprofilen ved 9-12 måneders efterundersøgelse. Success kriterier
    indbefatter normalisering af vævsprøverne og hormonprofilen.
