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   43801   clinical trials with a EudraCT protocol, of which   7259   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.

    17. The female subject is pregnant, plans to become pregnant during the course of the study, or is breastfeeding
    18. Female subjects of childbearing potential, beginning at menarche, who do not agree to use 1 highly reliable (ie, can achieve a failure rate of <1% per year) method of contraception from 7 d before the first dose of the study medication until 28 d after the last dose of study medication. Examples of highly reliable contraception methods include stable oral, implanted, transdermal, or injected contraceptive hormones associated with the inhibition of ovulation or an intrauterine device (IUD) in place for at least 3 m. One additional barrier method must also be used during vaginal sexual activity, such as a diaphragm, diaphragm with spermicide (preferred), or male partner’s use of male condom or male condom with spermicide (preferred), from Day 1/Randomization until 28 d after the last dose of study medication. Female subjects of childbearing potential are defined as those who are fertile after menarche, unless permanently sterile; permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. All female subjects of childbearing potential must have a negative serum pregnancy test result at screening (Visit 1) and a negative urine pregnancy test result, with positive results confirmed by serum, at every study visit from Day 1 (Visit 2) and after.
    Note: Before menarche, pregnancy testing and contraceptive use are not required. However, subjects and their parents/legal guardians must be advised that, immediately upon menarche, subjects will be required to begin pregnancy testing and initiate contraceptive use. This requirement cannot be waived.
    19. The subject has participated in a study of another study medication within 28 d before screening or plans to participate in such a study during the course of this study.
    20. The subject has had prior exposure to sparsentan.

    Subjects with a medical condition not listed above that may interfere with the evaluation of efficacy or safety-related outcomes for the study will be reviewed with the Sponsor’s Medical Monitor before consideration of the subject for enrollment.
