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   38002   clinical trials with a EudraCT protocol, of which   6235   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The objective of the study is to gain an indication of efficacy for five distinct combinations of bexarotene and betamethasone dipropionate in different concentrations, and one combination of tazarotene and betamethasone dipropionate compared to bland ointment (Vaseline®) and Daivobet® -ointment in the treatment of Plaque-Type Psoriasis.
    This is accomplished by comparison of the treatment areas over time as assessed by the area under the curve of the width of the echo-lucent band located at the dermo-epidermal junction, as measured by ultrasound at visits 1, 4, 8 and 11, as the primary endpoint.
    E.2.2Secondary objectives of the trial
    Secondary efficacy endpoints comprise: the percentage change of a score for scaling, for erythema and for induration in the treated area, as well as a total score (sum of the scores of these three distinct signs) and the development of the scores over time; the absolute and the percentage change from baseline over time of the width of the echo-lucent band. Safety and tolerability will be assessed by the physicians‟ assessment of tolerability for each formulation, and in addition by evaluation of adverse events and serious adverse events.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    -Male or female patients between 18 and 75 years of age with a diagnosis of stable plaque-type psoriasis (psoriasis vulgaris) for at least 12 months Psoriatic plaques that are suitable to be defined as target area lesions by the following criteria:
    o Psoriatic plaques must be located on the trunk and/or extremities. Plaques that are located on the head (incl. scalp), palms, sole of the feet, intertriginous or genitoanal areas are not suitable as target areas
    o Comparable psoriatic plaques with at least “2” in each score (range 0-4) for the three distinct signs: scaling, erythema and induration
    o No more than 3 points difference in total score (= sum of scores for scaling, erythema and induration Range 0-12) of the chosen comparable psoriatic plaques
    o Enough surface area to the psoriatic plaque to define eight clearly distinguishable (minimum distance between test areas: 1cm) test areas of at least 1 cm² size
    -Patient is willing and able to comply with the requirements of the clinical study protocol. In particular, patient must agree not to use prohibited concomitant therapy in the test areas and to avoid intense UV exposure of the test areas during the study -Written informed consent to participate in the study, prior to any study related procedures, indicating an understanding of the purpose of the study
    -A patient of childbearing potential agrees to use one of the following highly effective contraceptive methods for the duration of the study and for the 4 weeks after study drug discontinuation:
    o Combined oral, implanted or injectable contraceptives on a stable dose for at least 3 months prior to study entrance, OR
    o Partner who has been sterilized by vasectomy for at least 3 months prior to study entry, OR
    o Intrauterine devices (IUD) inserted for at least 4 weeks prior to study entrance, AND
    o Barrier methods (e.g. condom, cervical caps, diaphragm)
    Note: The investigator must inform all female patients of childbearing potential that bexarotene can potentially induce metabolic enzymes and thereby theoretically reduce the efficacy of oestroprogestative contraceptives.
    -Male patients with sexual partners who are pregnant, possibly pregnant, or who could become pregnant must use condoms during sexual intercourse for the duration of the study and for at least 4 weeks after the last dose of drug.
    E.4Principal exclusion criteria
    -Too small a body surface area covered with psoriatic plaques that meet the specified inclusion criteria
    -Any condition that may interfere with the study assessments or ultrasound measurements of the skin and/or may have an influence on the skin immune response (incl. open wounds)
    -Known adverse reactions of any severity or hypersensitivity to any ingredient of the test products or other retinoid
    -Not willing to avoid induction of heavy sweating, e.g. due to sauna visits, excessive sports activities during the study course
    -Not willing to avoid swimming, bathing or wetting of the designated test areas between visits
    -Pregnant or breast-feeding women
    -A medical condition that may put the patient at a general risk and therefore would prevent participation in the clinical study (including but not limited to: serious infectious diseases, major surgery within the last 4 weeks, or significant coronary artery disease, renal impairment, hepatic impairment, uncontrolled metabolic diseases, disorders of calcium metabolism, or autoimmune diseases)
    -History or presence of malignant disease (other than surgically removed basal cell carcinoma)
    - Current diagnosis of guttate, erythrodermic or pustular psoriasis
    -Patients who did not respect the following wash-out periods prior to study entry or do not restrain from using one of the following treatments during the study:

    Treatment Wash out period
    Topical treatment in the test area:
    Any topical anti-psoriatic drug: 2 weeks
    Products containing DEET (N,N-diethyl-m-polyamide), a common component of insect repellent products: 1 week
    Systemic treatment
    Biologics: 6 months
    Any other systemic antipsoriatic treatment (corticosteroids, ciclosporin, methotrexate, fumaric acid esters, acitretin etc): 3 months
    Procedures
    Phototherapy or artificial ultraviolet light via sunbeds: 4 weeks

    -Significant skin diseases other than plaque-type psoriasis (psoriasis vulgaris), including but not limited to: skin disease due to tuberculosis or syphilis, rosacea, perioral dermatitis, acne vulgaris, skin atrophy, striae distensae, increased fragility of skin blood vessels, ichthyosis, ulcers, wounds and reaction after vaccination
    -Significant skin infections (including but not limited to: herpes, varicella, mycotic skin infections (except for tinea pedis), bacterial skin infections or parasitic skin infections) -Excessive sunlight exposure within 28 days prior to study entry and during the conduct of the study

    -Participation in any other clinical study within 30 days prior or during this study -Patient is an adult under guardianship, hospitalized, deprived of freedom or unable to communicate or cooperate with the investigator due to language or mental problems
