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   44020   clinical trials with a EudraCT protocol, of which   7318   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.

    E.5 End points
    E.5.1Primary end point(s)
    The below primary endpoint will be investigated at a 'per patient' level:
    Incidence of complete eschar removal: Demonstrate superiority of NexoBrid over Gel Vehicle for eschar removal as measured by incidence of complete eschar removal assessed by a blinded assessor at the end of the topical agent soaking period (6 hours after start of the 1st topical application). Or, in case where 2 applications are performed, complete ER is assessed 6 hours after start of 2nd treatment.
    E.5.1.1Timepoint(s) of evaluation of this end point
    At the end of the topical agent soaking period
    E.5.2Secondary end point(s)
    The following secondary endpoints will be evaluated in this study and compared between NexoBrid and SOC.
    1. Reduction in surgical need- Demonstrate superiority of NexoBrid over SOC in reduction of surgical need for excisional eschar removal as measured by an analysis of incidence of surgical eschar removal (tangential/ minor/ avulsion/ Versajet and/or dermabrasion excision).
    2. Earlier eschar removal- Demonstrate superiority of NexoBrid over SOC in reduction of the time to achieve complete eschar removal.
    3. Blood loss- Demonstrate superiority of NexoBrid over SOC with regard to the blood loss incurred during the eschar removal procedures

    The following group of safety endpoints will be evaluated in this study and compared between NexoBrid and SOC. These endpoints are used to confirm that NexoBrid does have an inferior deleterious effect.
    1. Time to reach complete wound closure assessed in days, starting from Randomization.
    2. Cosmesis and Function - will be measured using MVSS, to demonstrate that treatment with NexoBrid does not have any clinically meaningful deleterious effect on burns scars quality as compared to the quality of burns scars treated with SOC, measured at 12 months from wound closure date, by a blinded assessor.
    3. Cosmesis and Function - will be measured using MVSS, to demonstrate that treatment with NexoBrid does not have any clinically meaningful deleterious effect on burns scars quality as compared to the quality of burns scars treated with SOC, measured at 24 months from wound closure date, by a blinded assessor.

    -time when complete eschar removal has been achieved.
    - time when complete wound closure has been achieved
