入选标准
- •-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.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 22
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 22
排除标准

- •-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

- •-History or presence of malignant disease (other than surgically removed basal cell carcinoma)

- •-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
- •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
