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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    • Diagnosis of osteoarthritis of the knee based on American College of Rheumatology criteria and functional capacity class of I-III.
    • Moderate to severe osteoarthritis at baseline.
    • Documented history indicating that subject has insufficient pain relief with optimal standard of care (SoC).
    • The investigator does not consider that any additional benefit can reasonably be expected from further adjustments to the patient's pain treatment.

    evaluated based on medical history and X-ray assessed by Central Readers, performed during Screening.
    • Other conditions that could confound discrimination of pain assessment in the index knee.
    • Clinically significant disease(s) or condition(s) that may affect efficacy or safety assessments, or any other reason which, in the investigator's opinion, may preclude the subject's participation in the full duration of the trial.
