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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    General information about the trial
    Main objective of the trial
    To assess the safety and tolerability of multiple ascending doses of Aurase Wound Gel when administered cutaneously (topically) to participants with Venous Leg Ulcers (VLU)
    Protection of trial subjects
    Study will be conducted in accordance with the requirements of International Council for Harmonisation Good Clinical Practice (ICH GCP), the Declaration of Helsinki (revised version of 2013), Good Manufacturing Practice (GMP), and the current national regulations and guidelines. The protocol will be approved by both the local ethics committee(s) (IEC) / institutional review board(s) (IRB) and regulatory authority(ices). Safety was evaluated based on adverse events (AEs), clinical laboratory tests, tolerability assessments, ECGs, concomitant medication review as well as a number of entry assessments (e.g. vital signs, medical history, physical examination) For each study cohort a sentinel patient was enrolled and safety data through at least day 8 was reviewed in a safety review meeting (sponsor and enrolling investigator attended). A safety review meeting was also conducted at the end of each cohort to determine whether it was safe to dose escalate in the next cohort.
