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   43841   clinical trials with a EudraCT protocol, of which   7281   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    The proposed study is designed to evaluate whether the combination of a progestin, norethisterone
    enantate (NET-EN), and an androgen, testosterone undecanoate (TU), represents a safe and effective
    method of male fertility regulation.

    E.1.2Version 9.1
    E.1.2Level LLT
    E.1.2Classification code 10065589
    E.1.2Term Male contraception
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The study is designed to address the following primary objectives:
    1. The rate of suppression of spermatogenesis induced by a regimen of NET-EN and TU
    administered every 8 weeks for up to 4 injection visits; and
    2. The level of contraceptive protection provided by the continued administration of NET-EN and
    TU every 8 weeks for an efficacy period of up to 56 weeks.
    E.2.2Secondary objectives of the trial
    Secondary objectives to be evaluated are as follows:
    1. Maintenance of suppression of spermatogenesis below the threshold criterion for contraception by
    the combined regimen, throughout the Efficacy Phase;
    2. Reversibility of the regimen as determined by the return of semen concentrations to ≥ 15
    million/ml or of total sperm numbers to ≥ 39 x 10^6, the lower reference limits (5th centile of the
    reference distribution) of a fertile population, as defined by current WHO recommendations
    3. Alterations in circulating concentrations of steroid and peptide hormones as a result of
    administration of this regimen;
    4. Safety, as monitored by reports of symptoms, examination findings, urine, and blood tests; and
    5. Hormonal regimen (method) acceptability.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    Men with persistently low sperm concentrations at month 12 of the recovery phase will continue to be followed and provided support and treatment on a case by case basis at the study’s expense until it is determined that they no longer need to be followed or until they decline further follow up. At these visits, only semen collections will be made. Analysis of recovery data will include only the first 12 months after entry into the Recovery Phase for all men.
