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   43974   clinical trials with a EudraCT protocol, of which   7312   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 ).

    General information about the trial
    Main objective of the trial
    The evaluation of the efficacy of the sunscreen RV 3131 A HC 3221 on the prevention of Polymorphic Light Eruption (PMLE) among subjects having PMLE history and for whom the diagnosis will be confirmed by a photobiologic exploration.
    Protection of trial subjects
    The study was conducted in accordance with Good Clinical Practice (GCP) based on guidelines of the European Economic Community and French law (20 December 1988, art. L209-7) and on the principles of the Declaration of Helsinki.
    Background therapy
    No other topical treatments including cosmetics were allowed on the test areas. However, in the event of a severe skin reaction with rash and/or burning sensation with marked discomfort for the patient, a topical corticosteroid could be prescribed at Day 7.
    Evidence for comparator
    This experimental design enabled the effects of any of the 3 strengths (1.0, 1.5 or 2.0 mg/cm²) of test compound to be compared with those of the vehicle alone (2.0 mg) versus untreated control (0 mg) areas in a group of patients with a history of PMLE, each patient being used as his/her own control. The within-individual design had the advantage of minimizing the unknown effect of patient-dependent confounding factors such as skin phototype, disease history, large individual variations in the UV-A1 threshold inducing PMLE reactions.

    Recruitment
    Recruitment details
    82 patients with a phototype II-V skin and a history of Polymorphous light eruption (PMLE) and negative antinuclear antibodies in 10 study centres were randomized.

    Pre-assignment
    Screening details
    A total of 90 patients from the usual patient population of the investigationnal sites were screened, however 8 patients were not randomized as they did not comply with inclusion/exlusion criteria. Screening of volunteers was performed prior to the first study drug application.

    Blinding implementation details
    The test compound and the vehicle were readily distinguishable and applied out of the sight of the investigator. However, the study personnel in charge of the application of the study products had access to the randomization list. A patient card was provided to the patients, with the name of a contact person authorized to give information about the product and the study.

    Primary: Lack of photodermatosis

    End point title
    Lack of photodermatosis [1]
    End point description
    The preventive activity of topic RV 3131 A HC 3221 was evaluated from the lack of photodermatosis development at endpoint on treated areas, with a positive control phototest. A phototest was considered positive if vesicles or papules appeared, and not only erythema, which might be due to irradiation. This criterion corresponds to a clear-cut diagnosis of PMLE flare (grade 1 or 2 on the global severity scale of PMLE flare). The preventive activity of the study treatment on the ITT population led to gradually increasing success rates (no photodermatosis) in 26 patients (76.5 %) treated with 1 mg/cm², 29 patients (85.3 %) with 1.5 mg/cm² and 32 patients (94.1 %) with 2 mg/cm².
    End point type
    Primary
    End point timeframe
    Lack of photodermatosis was measured between the first intake of study drug (Day 0) and Day 7 (clinical evaluation period) in the ITT population (patients with positive phototest on both control areas during the investigational phase N=34)
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: No statistical analyses have been specified because of the lack of a comparison arm (within-individual study desing)
