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   44306   clinical trials with a EudraCT protocol, of which   7355   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.2 Objective of the trial
    E.2.1Main objective of the trial
    To assess the superiority of rituximab compared to cyclophosphamide used in combination therapy with dapsone, to achieve CR or partial remission (PR) (corresponding in clinical practice to “almost Complete Remission”) of disease activity at Month 12, in patients with severe forms of MMP
    L’objectif principal de cette étude est de mettre en évidence la supériorité du rituximab par rapport au cyclophosphamide associé à la dapsone afin d’obtenir une RC ou une réponse partielle (RP) (ce qui correspond en pratique clinique à "une réponse presque complète") de la maladie à M12, chez des patients atteints de formes sévères de pemphigoïde des muqueuses.
    E.2.2Secondary objectives of the trial
    1-To compare the efficacy of rituximab and cyclophosphamide during the study (M6, M12, M18, M24) on:
    - Disease activity,
    - post inflammatory fibrosis and scarring from resolving lesions using a specific scoring system published by a panel of international experts: the Mucous Membrane Pemphigoid Disease Area Index (MMPDAI)
    - Rate of patients with major MMP complications such as: stenosis of the oesophagus, larynx or trachea or major eye impairment.
    -Rate of relapse/flare of MMP from the end of immunosuppressive therapy (Month 12) to the end of the study (Month 24).
    -Rate of patients with scarring sequelae necessitating an interventional procedure
    - Quality of life using the ABQOL and TAQOL
    2- To compare the tolerance of rituximab and cyclophosphamide (side effects)
    3- Biological assessment
    Les objectifs secondaires sont :
    1- Comparer l'efficacité du rituximab et du cyclophosphamide pendant la durée de l'essai (M6, M12, M18, M24) sur :
    - i) L’activité de la maladie,
    ii) La fibrose post-inflammatoire et cicatrices induites par la maladie à l’aide d’un score spécifique publié par un panel d’experts international : the Mucous Membrane Pemphigoid Disease Area Index (MMPDAI)
    - Le taux de patients avec des complications majeures liées à la pemphigoïde : sténose œsophagienne, atteintes laryngées, trachéales ou oculaires
    - Le taux de rechute/récidive de la maladie à l'issu du traitement immunosuppresseur (M12) et jusqu'à la fin de l'essai (M24)
    - Le taux de patients nécessitant une intervention pour des lésions cicatricielles séquellaires

    E.5 End points
    E.5.1Primary end point(s)
    Proportion of patients achieving complete remission (CR) or Partial Remission (PR) at Month12, defined as
    “CR: absence of any inflammatory lesion, blister or erosion, and, absence of new fibrosing lesions, and/or absence of worsening of established fibrosing lesions
    PR: presence of transient new inflammattory lesions, blisters or erosions that heal within one week without treatment and, absence of new fibrosing lesions, and/or absence of worsening of established fibrosing lesions

    (from slightly modified MMP International Consensus Statement definition).
    Le critère de jugement principal est le taux de patients étant en RC ou en RP à M12.
    la RC se définissant comme étant "l'absence de toute lésion inflammatoire, bulleuse ou érosive, et l'absence de nouvelles lésions fibrosantes, et/ou l'absence d'aggravation des lésions fibrosantes déjà existantes".
    La RP correspond à la présence de nouvelles lésions inflammatoires transitoires, de lésions bulleuses ou érosives qui régressent spontanément en moins d'une semaine, et l'absence de nouvelles lésions fibrosantes, et/ou l'absence d'aggravation des lésions fibrosantes déjà présentes.
    (d'après la définition légèrement modifiée du MMP International Consensus Statement)
    E.5.1.1Timepoint(s) of evaluation of this end point
    M12
    M12
    E.5.2Secondary end point(s)
    • Efficacy on disease activity:
    - Mean evolution of MMP DAI activity score from Week 0 to Week 104
    - Time to achieve CR or PR
    - Cumulative duration of periods of CR or PR during the study
    - Number of flares / relapses during the study.
    - Time to disease flare/relapse
    - Quality of life measured at baseline, M3, M6, M12, M18 and M24 by the AB QOL and TAB QOL scores, which are quality of life questionnaires specifically developed for patients with autoimmune blistering diseases.

    • Efficacy on prevention of post inflammatory fibrosis and scarring from resolving lesions:
    - Mean evolution of the MMP DAI damage score from Week 0 to Week 104 including:
    - Ocular involvement assessed by ophthalmologists using the MMPDAI eye subsection score.
    - Rate of patients developing new laryngeal, tracheal or oesophageal stenosis.
    - Proportion of patients with new scarring sequelae necessitating an invasive procedure from Week 0 to Week 104.

    • -Tolerance:
    - Number of Serious Adverse Event, (SAEs) including fatal, Non-Serious Adverse Event, SAEs leading to drug discontinuation/withdrawal of the patient from the study (using Common Terminology Criteria for Adverse Events (CTCAE and MeDRA terminology),
    - Number and causes of death during the study

    • -Biological assessment
    -Decrease of serum antibodies directed against the different target antigens of BMZ involved in MMP (BP180, laminin 332, type 7 collagen) by ELISA assays
    - Affinity of corresponding auto-antibodies;
    - Evolution of the number of BPAG2- specific peripheral blood B lymphocytes measured by ELISPOT assay, in both treatment groups.
    Les critères de jugement secondaires sont :
    Efficacité sur l'activité de la maladie :
     Evolution moyenne du score d'activité MMPDAI de la semaine 0 à la semaine 104
     Délai d'obtention de la RC ou de la RP
     Durée cumulée des périodes de RC ou de RP pendant l'essai
     Nombre de poussées/rechutes pendant l'essai
     Durée des poussées/rechutes
     Qualité de vie évaluée à M0, M3, M6, M12, M18 et M24 par les scores AB QOL et TAB QOL, qui sont des questionnaires de qualité de vie adaptés spécifiquement aux patients atteints de dermatoses bulleuses auto-immunes et validés en Français

    Efficacité sur la prévention de la fibrose post-inflammatoire et sur les lésions cicatricielles:
     Evolution moyenne du score lésionnel MMP DAI de la semaine 0 à la semaine 104 incluant :
    o l’atteinte oculaire évaluée par les ophtalmologues en utilisant le score oculaire du MMP DAI
    o - le taux de patients développant de nouvelles sténoses laryngées, trachéales ou oesophagiennes
     Taux de patients nécessitant un geste invasif pour de nouvelles lésions cicatricielles séquellaires entre les semaines 0 et 104

    Tolérance:
     Nombre d'effets indésirables sévères (grade 3 ou 4 de la Common Terminology Criteria for Adverse Events (CTCAE), incluant le décès
     Nombre et étiologies des décès au cours de l'étude

    Evaluation biologique :
     Décroissance du taux d'anticorps sériques dirigés contre les différentes cibles antigéniques de la jonction dermo-épidermique mises en jeu dans la Pemphigoide des muqueuses (BP180, laminine332 : collagène de type 7), par méthode ELISA
     Affinité des anticorps correspondants
     Evolution du nombre de lymphocytes B périphériques spécifiques de BPAG2 mesuré par ELISPOT dans les deux groupes.
