Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35495   clinical trials with a EudraCT protocol, of which   5837   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).

    General information about the trial
    Main objective of the trial
    To demonstrate the efficacy of a 4-week treatment by the emollient V0034CR in reducing the disease severity assessed by a specified symptom sum score (SRRC: Scales Roughness Redness Cracks fissures score) on both legs.
    Protection of trial subjects
    The study was conducted in accordance with the principles of the Declaration of Helsinki and subsequent amendments thereto, the Good Clinical Practices (CPMP/ICH/135/95) and local legal régulations. Patient underwent a health assessment at the start of the study and remaines under regular Medical control during the whole study

    Recruitment
    Recruitment details
    A total of 265 patients were included in the study and randomized in the two treatment groups. The study was performed in 12 countries and involved 21 centres. Among randomized patients, a total of 9 patients (3.4%) did not complete the study 3 (2.3%) in Vehicle group and 6 (4.5%) in V0034CR group. The main reason was lost to follow-up

    Pre-assignment
    Screening details
    Patients under 18 years suffering from a non-bullous form of ichthyosis with SRRC global score >=4 and scaling SRRC >=2 on both external faces of the legs. A double-blind period (V0034CR or vehicle) during 4 weeks followed by an open label period with all patients treated by V0034 CR for 8 weeks.

    End point description
    The primary efficacy criterion was the response to treatment defined by a decrease of at least 50% of the SRRC score on the external face of legs (mean of the 2 legs) between baseline and Day 28. The main analysis of the primary efficacy criterion was performed on the FAS population (All countries) using the Cochran Mantel Haenszel test stratified by centre.

    [1] - The CMH test was performed on the FAS including all countries to assess whether the response (i.e. decrease in the SRRC score by at least 50% on Day 28) was independent of treatment (explanatory variable) when adjusting for group of countries.
    [2] - The difference between the two treatment groups was statistically significant (p=0.008) adjusted for pooled centres.
