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   44339   clinical trials with a EudraCT protocol, of which   7369   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    The purpose of the trial is to evaluate the effectiveness of BioFOAM maggots in achieving rapid debridement of chronic venous leg ulcers. Removal of slough and necrotic tissue from these wounds is essential if the wound is to heal effectively.
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the clinical effectiveness of BioFOAM maggots in the debridement of sloughy venous leg ulcers
    E.2.2Secondary objectives of the trial
    To assess whether the use of maggots expedites healing when compared to standard treatment (compression bandaging).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1) Patient is at least 18 years of age.
    2) Ankle Brachial Pressure Index >/= 0.85 N.B. calculations to be made using Doppler ultrasound measurements from both dorsalis pedis and posterior tibial arteries to minimise error (standard procedure).
    3) Patient has a venous leg ulcer, located between the knee and ankle (at the level of, and including, the lateral and medial malleoli). The ulcer must be confirmed as of venous origin by venous duplex ultrasound.
    4) Patient’s ulcer is a minimum of 4 cm2 and a maximum of 100 cm2 on initial screening.
    5) Patient’s ulcer is covered by a minimum of 20% slough calculated using the manual and computer-aided planimetry method).
    6) Patient understands and is willing to participate in the clinical study and can comply with the follow-up regime.
    7) Patient has read the patient information leaflet and signed the Local Research Ethics Committee approved informed consent form before screening and commencement of trial treatment.
    E.4Principal exclusion criteria
    1) Patient’s ulcer should not show exposed blood vessels, tendon, muscle or bone.
    2) Patients with a history of a bleeding disorder that, in the opinion of the researcher, would make compliance with the trial protocol medically unsafe.
    3) Patients who are unable to understand the aims and objectives of the trial.
    4) Patient has any condition(s), which seriously compromises the patient’s ability to complete this study, or has a known history of poor compliance with medical treatment.
    5) Patient has an aversion to maggots, despite careful and informative discussion between researcher and patient and explanation of the benefits of maggots
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome is the time to debridement of the study ulcer. Successful debridement is defined as minimal slough that does not, in the clinical opinion of the researcher, require the application of a further treatment specifically for debridement.

    All participants will be followed up by the research team for up to 12 weeks or until the study ulcer has healed if this is sooner.
