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   43974   clinical trials with a EudraCT protocol, of which   7312   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.

    9. Patient’s living donor gave written consent for trial participation
    10. Ability to understand the nature and scope of the clinical trial
    11. Written informed consent given prior to any trial-related procedures
    12. Female patients of childbearing potential must:
    a. have a negative pregnancy test (blood) at Screening.
    b. either commit to true abstinence from heterosexual contact or agree to use, and be able to comply with, 2 highly effective measures of contraception control (failure rate less than 1% per year when used consistently and correctly) without interruption, during the trial participation. Patients who discontinue mycophenolic acid derivate during the trial participation can switch to 1 highly effective contraceptive method 6 weeks after the end of mycophenolic acid derivative treatment. Reliable methods for this trial are: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, sexual abstinence or vasectomized sexual partner. Abstinence from heterosexual contact is only accepted as true abstinence: when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods and withdrawal] is not an acceptable method of contraception.) Postmenopausal (no menses for at least 1 year without alternative medical cause) or surgically sterile female patients (tubal ligation, hysterectomy or bilateral oophorectomy) may be enrolled.
    c. agree to abstain from breast feeding during the trial participation.
    13. Male patients must practice true abstinence or agree to use a condom during sexual contact with a pregnant woman or a woman of childbearing potential during the trial participation and for at least 90 days after the end of trial participationmycophenolic acid derivative treatment, even if he has undergone a successful vasectomy.
