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.

    Clinical Trial Results:
    A multi-centre, open-label, phase 1 study, Part A single ascending dose and Part B multiple dose, to evaluate the safety, tolerability and pharmacokinetics, and to explore early signs of effectiveness of induction of antigen-specific immune tolerance with TPM203 in pemphigus vulgaris patients

    General information about the trial
    Main objective of the trial
    To evaluate the safety and tolerability of the intravenous infusion of TPM203 in pemphigus vulgaris (PV) patients.
    Protection of trial subjects
    The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) for review and approval before study initiation. All revisions to the consent/assent forms after initial IEC approval were submitted by the investigator to the IEC for review and approval before implementation in accordance with regulatory requirements. This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    03 Oct 2019
    Amendment 1 incorporated the changes requested by the German Health Authorities and the Leading EC in Marburg, respectively, and were implemented before screening of any patient was initiated.
    29 Oct 2019
    Amendment 2 incorporated the changes requested by the German Health Authorities and the Leading EC in Marburg, respectively, and were implemented before screening of any patient was initiated.
    28 Feb 2020
    Amendment 3 incorporated corrections and clarifications based on the experience gathered screening and treating the first patient, including the following: - the interval mandating a Screening Confirmation Visit was prolonged from 8 to 12 weeks, - the upper limit of the body mass index was set to ≤32, instead of ≤30 - the usage of steroids other than prednisolone was clarified.
    16 Jun 2020
    Amendment 4 incorporated a SARS-CoV-2 infection / COVID-19 risk assessment, the implementation of adequate measures to minimize the SARS-CoV-2 infection risk and rules to prevent an IMP administration to a SARS-CoV-2 infected patient.
    11 Oct 2020
    Because of recruitment difficulties, the study was extended to include additional German sites as well as additional international clinical sites with Amendment 5
    02 Nov 2021
    Amendment 6 incorporated the use of additional methods for detection of anti-Dsg3 serum IgG and the inclusion of patients carrying HLA-DRB1*04:02 and/or HLA-DQB1*05:03. The permitted use of systemic corticosteroids was adjusted to body weight. The collection of patients’ sera for analysis of anti-Dsg3 IgG antibodies was extended for 3 month and SARS-CoV-2 specific rules were adjusted to current pandemic status.
